And they thought that this was enough for the eyes. However, a former Apple Store support employee, who knows much more about the operation of the iPhone than any of us, wrote an amazing article on his blog about the phone’s battery, which we present below without cuts.
I worked at the Genius Bar for almost two years and the most difficult problem I had to face was the short battery life. It was incredibly difficult to find the reason why the battery drains so quickly for many people.
I set myself the goal of finding specific reasons for rapid battery drain on iOS devices. This article is the result of my years of research and experience gained during my time as an iOS Genius and Specialist, as well as tests conducted on my and my friends' devices.
The recently released iOS 7.1 brought many changes, including design changes and performance improvements. However, some users complain about deteriorating battery life and many blogs present this as a fact.
This is not going to be another “Turn off all useful iOS features” article. My goal was to provide practical steps to solve your iOS battery problems.
Before we begin, I should note that 99.9% of battery problems have nothing to do with iOS at all. I guarantee that if you reset your phone to factory settings with no apps or email left on it, it will last forever on battery life. However, no one uses their devices this way, and in fact, no one should use them this way. Hopefully, with these steps, your iOS device's battery life will noticeably improve while you continue to use all the apps and features you love.
But first you need to check if you really have a problem.
How to Check Battery Life on iOS
Using the already built-in test - Usage and Waiting indicators, as well as very simple calculations, you can find out if you have a problem. Go to Settings > General > Statistics and check your results.
The time in the Usage column shows how long you have been actively using your device. Waiting, in turn, shows how long the device has been in sleep plus the Usage time. A better name for the Standby column would be “Total operating time since last charge.” The main thing is that you need to ensure that the Use time is much less than the Waiting time. An exception would be if you have used the device every second since you disconnected it from the charger. If this is not the case in your case and your Usage Time is equal to your Wait Time, you have a serious problem. The bottom line is that the usage time should be equal to the time the device was used from the moment it was removed from the charger.
So here's the test: record your Usage and Standby metrics, press the screen lock button to put your device to sleep, and put your phone aside for five minutes. When you return, look at the change in opening hours. If your device goes to sleep properly, the Standby time should have increased by five minutes and the Use time by less than a minute. If your usage time increases by more than a minute, you have battery life problems. Something is preventing your device from going to sleep, significantly reducing battery life.
If you don't have such a problem, great! You do not need the steps described in this article. But if anyone you know is constantly complaining about short battery life, keep reading or send them a link to this article.
Below are the top reasons I've found for fast battery drain on iOS and tips on how to fix them.
Step 1: Turn off Location Services and Content Updates for Facebook
(Settings -> General -> Content Update)
The first step may seem very specific, but that is only because it is very common and very effective. It has also been thoroughly tested and verified on many devices.
I received the iPhone 5s about two weeks ago and it seemed like the battery was draining very quickly. Being the geek that I am, I decided to run the Instruments app in Xcode, Apple's development environment, to find the problem. Instruments is an Activity Monitor for your iPhone, allowing developers to see every process currently running and how much memory and CPU power each app is using in real time.
During the test, Facebook was constantly in the list of active processes, even though I was not using it. So I tried turning off Location Services and Content Updates for Facebook and you'll never guess what happened: the percentage of charge remaining increased from 12% to 17%. Wow. I've never seen this on an iPhone. As far as I remember, the iPod Touch repeats this behavior, although it's been quite a while since I last checked. On iPhone, the percentage of charge remaining is usually consistent.
I was able to replicate this behavior on several iPhones with the same result: if you remove background Facebook features, the battery percentage increases.
Bad, Facebook, very bad.
Step 2: Remove Content Updates for Apps You Don't Care About
My recent post explains the benefits of the Content Update feature. This is a great feature added in iOS 7, but it's not absolutely necessary to leave it enabled for all apps that support it. Turn off Content Updates for Facebook or other apps that don't require constant updates.
If there are apps that you open regularly and you trust the quality of the app and the developer, go ahead and turn on Content Updates and enjoy how they are smartly updated and ready to use as soon as you open them. Content refresh is a great feature if you need it, but it's not needed for every app on your iOS device.
Step 3: Stop closing apps while multitasking
iOS 7 has made closing apps a very pleasant experience: All you have to do is double-tap the Home button and swipe up on an app to send it into a digital black hole.
Many people say that closing apps will increase your battery life because apps won't run in the background.
Wrong.
Yes, it closes the application, but you won't even know what you're doing worsen battery life if you do this constantly. Let me explain.
When you close an application, you remove it from RAM. This may seem like a useful activity, but it is not. When you open the same app again, your device loads it into memory again. This loading of an app in and out of memory puts more stress on your phone than if you left it alone. Plus, when you need more storage, iOS closes apps automatically so you can do the work your device already does for you. The device is intended for you to use, not to act as a cleaner.
In fact, all those apps you see in the multitasking menu aren't running in the background: iOS freezes them the moment you exit the app, so it's ready to go when you want to return. Unless you have enabled Content Refresh, the app is not allowed to run in the background. Exceptions are cases when the application plays music, uses Location Services, records sound, or, most secretly, checks for incoming VOIP calls, as, for example, Skype does. All of these exceptions, except the last one, display an icon next to the battery indicator, warning that the application is running in the background.
Step 4: Temporarily turn offPushfor email
If steps 1-3 don't solve your problem, try to see if turning off Push for email helps. Push allows your device to receive instant notifications every time you receive an email. A useful feature if you absolutely need to know when each message arrives, but it can have a negative impact on battery consumption if configured incorrectly.
I've seen many devices where Push is the main cause of battery drain, but I've also seen many devices with Push enabled that have excellent battery life. In fact, it all depends on the server settings and the specific email. Try changing the Sampling settings to every hour, thirty, or fifteen minutes and see if the rapid battery drain stops. If this doesn't help, turn Push back on. You can also try turning off Push for individual accounts if you have multiple accounts. Just check using the test described above if this helped solve your problem.
Incredibly often especially with by email Exchange, a situation occurs where the phone seems to go into a loop, constantly checking email. When this happens, the device will discharge in approximately six hours and the Standby and Usage readings in Settings > General > Statistics will be identical. These values are the same not because the firmware is damaged, but because the phone constantly checks for new mail and does not allow the phone to go into sleep normally.
Step 5: Turn offPushnotifications for apps that bug you
Are you familiar with the situation when the game your child has installed constantly sends notifications asking you to buy sheep for an online farm? If yes, then every time you receive such a notification, your phone wakes up for a few seconds to turn on the screen and waits for your potential actions.
Default notifications don't drain your battery too quickly, so don't rush to turn them all off. However, each message wakes up your device for 5-10 seconds and this can add up. If you receive 50 notifications a day and don't do anything about them, that adds 4 to 8 minutes to your Usage Time, which in turn reduces the amount of time you can use your device.
Turn off those annoying notifications for apps you don't want to receive them from. The difference may seem small, but it adds up over time.
Step 6: Turn off battery percentage display
You heard right.
Turn off the battery percentage display and stop worrying about your battery running low. You can find this in Settings > General > Statistics, right above battery life.
What I've noticed while working at the Genius Bar is that people who are concerned about the battery life of their iOS device are constantly checking how much percentage is left and how much has changed since the last check. And if you turn on your device twice as often just to check how much charge is left, you're essentially cutting your battery life in half.
Stop worrying about it and enjoy life. There are more important things to worry about than battery level. The desire to control may haunt you at first, but then you will get used to it.
Step 7: Head toApple Store
Update: After posting I was notified that the battery test fromAppleonly works oniPhone 5and higher
I know you hate making an appointment at the Genius Bar, it's loud and crazy, but there's... good reason why I added this item to the list.
As far as I know, Apple has added a “Battery Life Test” to all iOS specialists. This test allows you to view a detailed report on the battery usage of your device. It takes a few minutes, and from what I've heard, the results are comprehensive. I haven't seen this test myself, but my friends say it's good.
There is still a possibility that your battery has a defect, and specialists can replace it for free if the device is still under warranty, or very cheaply if the warranty has expired.
Step 8: Turn on Airplane Modein places with weak cellular signal
One of the main reasons why your device's battery may drain quickly is a weak cellular signal. When iPhone detects that the signal is weakening, it increases the antenna power to maintain the connection to be able to receive calls (basic) and maintain a data connection.
In case you are constantly in an area with only one stick or out of the area altogether, this can quickly destroy the battery power of your device. Unfortunately, this can happen in more places than one might initially imagine - any building with metal studs, aluminum buildings, buildings with dense concrete walls, densely populated cities, and city centers with many high-rise buildings.
It's often the case that you have a strong signal on higher floors, but simply moving to lower floors, such as a basement, will cause your iPhone to cling to that signal as if its entire existence depends on it, thus quickly draining the battery. It's worth noting that this rapid battery drain happens even if you have a good Wi-Fi signal because the phone requires a cellular connection for calls and SMS messages (green messages in the Messages app).
If you are in a weak signal area and need to receive calls, I have for you bad news- you can't help it. But if the signal is so weak that you can't receive calls anyway, I recommend turning on Airplane mode. You can turn it on by swiping up from the bottom edge of the screen to get to the Control Center and tapping on the Airplane Mode icon.
One thing you may not know is that in Airplane Mode you can turn on Wi-Fi. Just click on the Wi-Fi icon in Control Center (the icon to the right of the Airplane Mode icon). This is ideal for places like an airplane where you have no range at all but do have a strong Wi-Fi signal.
If you are connected to a Wi-Fi point, you can turn off data transmission, for example, EDGE, 3G, 4G or LTE. Many people do not know that the phone receives two signals at the same time: one for calls and SMS, the second for data transfer.
iPhone signal strength only shows the signal strength for a non-data connection, which means that theoretically your iPhone could show 2-3 sticks (or dots on iOS 7) for the first connection, but in reality you get 1 stick LTE/4G/3G connections, which forces the phone to search diligently for a connection. To turn off data only on your iPhone, head to Settings > Cellular and turn off data. Again, this will make it possible to receive calls (if you still have a signal) and use Wi-Fi to transfer data.
Conclusion
I guarantee that if you follow these tips you will get best time battery life on your iPhone, iPad or iPod Touch.
If your device still cannot survive the whole day and you are unable to go into the noise chamber from of stainless steel, which I lovingly call your local Apple Store, don't worry. There is hope.
The reason why your phone doesn't last all day could simply be because you're a very active user and your iOS device behaves completely normally in the conditions it encounters. The problem is not with the device or even with you. You are simply using the device beyond its capabilities. My advice for you is to buy a car charger, a second charger for work/travel, or a battery case to extend battery life.
I hope this article will help you stop worrying about the battery life of your device and you can enjoy the device that is in your hands. There are many important things in life that deserve our attention, so the less we are distracted by little things like battery life, the more time we can spend on the people and problems that really matter.

Website
We have repeatedly touched on the issue of how to extend autonomous iPhone work and they thought that this was enough for the eyes. However, a former Apple Store support employee, who knows much more about the operation of the iPhone than any of us, wrote an amazing article on his blog about the phone’s battery, which we present below without cuts. I worked at Genius Bar for almost two years and...Google annually adds many settings and functions to the Android operating system, many of which are hidden from the eyes of ordinary users. This was done on purpose, but with good intentions. The American corporation believes that if an inexperienced owner of an inexpensive Android smartphone accidentally activates certain important settings, then his device may start to work slower or discharge much faster, so right out of the box all smartphones based on Google's OS have only Basic activated functionality, but it is very easy to fix.
Although every year all smartphones work longer on a single battery charge, largely due to better software optimization for hardware, a hidden setting in all Android smartphones significantly increases battery life, and can now be activated absolutely anyone, since it is definitely available in any custom firmware and in all models of mobile devices.
All smartphones based on the Android operating system have an incredibly large reserve of power, which is simply excessive for solving simple everyday screens. It's like driving a car, sometimes pressing the gas to the floor, and then slowing down again. In the case of smartphones, it’s not the gas that drains faster, it’s the charge. battery. To increase battery life mobile device you need to launch “Settings”, and then go to the “Battery” section.
In the “Battery” section, three vertically located dots should be visible in the upper right corner, which you need to click on. In the menu that appears, you will need to select “Power Saving Mode” and then activate it. As a result, processor performance will be reduced, which will allow up to 50% increase in battery life on a single battery charge. This feature is available in all smartphones and tablets running Android 5.0 Lollipop and higher.
To achieve an even greater effect, the editors of the site recommend installing the “Doze-energy-saving” application, which significantly increases the battery life of all Android smartphones, since a lot of charging is “eaten up” by processes running in the background, which the user does not even see. After installing it, you need to select from the list only those programs and services that should continue to function normally.
It is worth choosing the most basic instant messengers, email clients and other basic programs that should receive notifications in real time, and not with a delay. This program works in such a way that all processes that are running in the background and consuming battery power are automatically frozen. This does not cause any harm to them or the data stored in them, and using this application can significantly increase battery life by up to 40% of the standard. This is especially noticeable at night, when without this program the smartphone’s battery will be discharged by 10-12%, and with it only by 5-6%.
We will find a way to increase the operating time of the device in normal mode, when calls are made, notifications are delivered, and applications fly.
Modern smartphones from model to model are becoming smarter, more capable, more productive - and more voracious. Most of the time, devices are in standby mode, but even so they rarely last more than one or two days without recharging. Let's try to increase the battery life of the gadget from the inside - using system settings and advanced applications.
The most energy consumed is the screen backlight, maintaining GSM, LTE and WiFi signals, as well as processor operation. We will not describe extreme methods of extending the life of a smartphone: switching to black and white, reducing brightness to the maximum, or turning off all sensors and transmitters. It’s more interesting to find a way to increase the operating time of the device in normal mode, when calls are made, notifications are delivered, and applications fly.
To do this, you need to force the smartphone to do only what is required at the moment, and “sleep” the rest of the time. Count how long your cell phone is in your pocket, on your desk, or next to your bed. Yes, most of the day!
We will fight for operating time using built-in Android tools, applications that do not require root rights, and advanced “geek” programs. To do this, we will have to delve a little deeper into the theory to understand where the potential we need is hidden.
Standard means
Android's built-in energy-saving capabilities are expanding from version to version. A radical breakthrough in this direction occurred when Marshmallow introduced a new sleep algorithm, Doze Mode. It is activated at the moment when the phone is not connected to charging and lies motionless. After half an hour to an hour of inactivity on the part of the user, Doze sends all applications into deep sleep (App Standby), giving them the opportunity to contact the outside world after 1, 2 and 4 hours.
It is possible to configure mode changes based on events: when the charge remains below a certain value, by time, and by the fact of connecting to charging.
The application is very clear; it shows the consumption graph, the most power-hungry programs, and the estimated operating time in different modes. In addition, the program promises to influence the charging progress of the phone in order to increase battery life.
Essentially, this is a kind of command center where you can monitor the device’s energy consumption by setting up general policies. Battery Saver cannot actively interfere with the operation of programs, but it copes well with managing OS settings.
In contrast, the Greenify application specializes in taming programs that often wake up the phone from rest - so-called Wakelocks. Let's remember the theory. When we press the power button or simply leave the mobile phone unattended, its screen goes blank, Android tries to put the device into a suspend state, in which the computing cores are disabled and only the RAM is supplied with voltage. Running applications, which can work in the background, prevent the device from going into this mode; a lock called Wakelock is used. If the gadget is already in suspend mode, the application can wake it up at the right time using the AlarmManager object. In practice, this manifests itself in the fact that your phone suddenly wakes up, accesses the Internet, rings about notifications, and then gets ready for bed again.
The more often a device is activated, the more energy it spends. This means we need to catch applications and services that abuse wakelocks and forcefully freeze them. In order to find out who is naughty, you will need a special utility, for example, Wakelock Detector. The application requires root rights or a tricky installation by connecting the phone to the PC in debug mode. But the result is detailed statistics, which process has disturbed the system how many times since the last time the device was charged.
If you are too lazy to tinker with the utility, just try to keep track of who is constantly at the top of the energy consumption statistics. This will allow you to decide on candidates for hard freezing.
But back to Greenify, it is designed to “greenify” selected applications immediately after turning off the screen. This program is very concise. When you launch it, in the list of available programs you need to select those to which you want to apply automatic hibernation. And that’s it, you don’t need to log into Greenify anymore, it won’t annoy you with any notifications or reports. And you will feel the result on the same day.
With root rights and the Xposed framework installed, the application can “greenify” system processes, track the reasons why applications exit hibernation, and “freeze” even the most tricky of them. Greenify can also control the operation of the processor. At a given frequency, it collects a queue of application requests to the processor and then “en masse” sends them to be executed. Due to this, the total time the CPU spends in active mode is noticeably reduced. Perhaps this is the most useful program for increasing the operating time of a mobile device.
ROOT to help
For those who have acquired superuser rights on their device and are not afraid to delve deep into the software, there are advanced applications. One of them, Amplify, is similar to Greenify in its feature set, but offers more fine-tuning. For example, you can set the period in seconds at which each process can wake up the system. In addition, Amplify suppresses the main system processes that consume energy: NlpWakelock, NlpCollectorWakeLock, ALARM_WAKEUP_LOCATOR and ALARM_WAKE_ACTIVITY_DETECTION. In general, a useful thing in capable hands.
Owners of smartphones with modern versions of Android that support Doze mode will definitely like the ForceDoze and Doze applications, which allow you to change the time before entering deep sleep mode and configure other conditions. These programs create a “white list” of applications that can wake up the phone even during the deepest sleep.
The applications listed above, when used correctly, will extend the operating time of your devices by at least several hours, but provided that you let them out of your hands at least for a short time.published
Modern mobile gadgets are becoming more and more intelligent and productive, but their gluttony is literally growing exponentially. Even with moderate use of the phone, when it is in standby mode most of the time, you have to recharge the device after a day or two. Let's look at how to increase your phone's battery life and prevent it from turning off at the most inopportune moment. You can increase the operating time of your gadget by using advanced applications and system settings.
Why is the phone so power hungry?
The most energy-intensive areas of a mobile device are:
- Supports LTE, Wi-Fi and GSM signals.
- Processor operation.
- Screen backlight.
Let's consider useful tips, how to increase the battery capacity of your phone, according to the principle “from simple to complex.”
additional battery
This advice is for owners of mobile devices where it is possible to purchase an extended battery. You just need to study the characteristics of the smartphone to understand whether something like this is possible or not.
Important! Along with the additional battery, you will have to buy an additional cover with greater depth. In this case, the phone will become one and a half times thicker.
How to extend your Android battery charge? Portable charger
This is a battery that is recharged from an outlet. Its capacity ranges between 1200 and 20000 mAh, which is 5-10 times the battery capacity of the phone. On a long trip, such a device turns out to be invaluable. Using a charger, you can stay connected for about 10 days without compromising the functionality of your mobile device. Read our separate review, where you will find all useful information about Power Bank.
Important! The only drawback of the additional battery is its relatively large mass, about 2 times more than the smartphone itself. So you'll have to sacrifice some mobility.
Device optimization
If you can’t solve the issue with a portable charger and (or) an additional battery, you can try to optimize the gadget. The idea is to manually disable unused functionality and thereby increase the phone's battery life.
Decrease display brightness
According to statistics, the display backlight takes the lion's share of energy. To reduce the brightness, use the “Display” item and set a lower brightness value. If desired, you can set automatic regulation.
“No” to live wallpapers
Live wallpapers place a significant load on your phone's GPU. Simply replace them with a beautiful image, and the problem will be solved. And so that you don’t feel like your screen has become boring, take advantage of our practical ideas for setting wallpaper on Android.
How to reduce the automatic screen shutdown time?
The essence of this event is as follows: after a call or SMS, the screen will go dark not after 5 minutes, but after a few seconds, which will save battery. To reduce the shutdown time, follow this algorithm:
- Go to Settings.
- Select Display.
- Set the desired time until the screen turns off.
Disabling unused features:
- If your gadget is equipped with a GPS module, turn it off when not in use. You will see the result immediately.
- Keep an eye on the Wi-Fi module. If there is no connection to a Wi-Fi point, the module constantly searches for the network and notifies you of a successful search. Naturally, the charge is used in this case. If there is no need for a Wi-Fi router at the moment, then why not turn it off?
Important! The same can be said about Bluetooth in the background.
Using additional software
Of course, if your Android battery is draining quickly, you can take such extreme measures as switching to black and white mode, reducing the brightness as much as possible, and turning off all sensors as much as possible. But this is, to put it mildly, uninteresting.
It is much more effective to find a solution to the problem when the gadget is functioning in normal mode: applications “fly”, SMS are received, and calls are made at once. The essence of the “economy” mode is that, if necessary, the device functions normally and “sleeps” for the rest of the time. Just for fun, count how long the phone is in your pocket, bag, or just lying on the table next to you. There is only one answer: most of the time!
Using Standard Features
The energy-saving capabilities built into the Android OS are becoming more advanced from version to version. An example is Doze Mode sleep mode. It is activated when mobile phone does not charge, lies motionless. About half an hour of such immobility, and the smart program sends the applications to sleep. At the same time, it gives them the opportunity to contact the outside world in 1, 2 and 4 hours.
This mode has been improved for Andriod 7.0 Nougat:
- “Sleep” starts in less than half an hour.
- The mode is independent of information received from motion indicators. Thus, the transition is possible if the phone is not lying on the table, but is in your bag or pocket.
- Economy mode always works and cannot be turned off accidentally.
Important! Thus, the newer the OS on a mobile gadget, the longer the period between two recharges. There is an opportunity to update the “OS” - do it and don’t think twice about it. But even for existing older systems, you can find applications that will reduce the power consumption of the device.
Possible improvements within the existing OS
There are many applications that extend the activity of the gadget between two battery charges. There is no point in installing everything on your smartphone. This will only reduce the effectiveness. Practice shows that the “sweet couple” of the Go Battery Saver and Greenify applications is suitable for most Android mobile devices.
GO Battery Saver
This is a “smart” control application for basic settings. Using the “Mode” tab, you can configure the algorithms for turning off Bluetooth, Wi-Fi and data transfer.
Important! The application can automatically change the processor frequency to maximize savings.
It is possible to configure mode changes based on events:
- By time.
- When connected to a power source.
- If the battery charge remains below the specified value.
In essence, this is a command post from which you can monitor the gadget’s energy consumption using simple settings. Battery Saver does not interfere with the operation of programs, but manages them skillfully.
Greenify
This is a fundamentally different application, a kind of software “tamer”. If the mobile device is at rest, its screen goes blank. operating system puts the gadget into suspend mode, in which the computing cores are turned off, the voltage is transferred only to the RAM. If necessary, the AlarmManager device “wake up” the phone. At the same time, keep track of which programs are TOP in terms of energy intensity. These are the candidates for freezing.
The Greenify application itself is designed to greenify these programs. Launch Greenify and check the list of programs for automated hibernation. You can feel the result immediately. Greenify can also work with the processor, so much so that the time the CPU spends in active mode is significantly reduced.
Important! Many users find this program the most useful for optimizing energy consumption. Similarly, you can increase the battery life of your laptop.
Video material
As you can see, there are many ways to reduce the energy consumption of a mobile device. Choose the one that suits you best and enjoy the stable operation of your favorite gadget.
Long-term battery life of a smartphone during a hike or tourist trip is ensured in several ways. Among them are the choice of a device with a powerful battery, the presence of a second battery, the use of external portable chargers and Powerbank. But even if you have an ordinary smartphone with an ordinary battery and no external batteries or chargers, it is quite possible to increase autonomy by optimizing the functions of the communicator itself.
10 Ways to Increase Battery Life
1. Lower the brightness level and turn on sleep mode.
This is perhaps the most suitable battery saving method, which is equally suitable for any device equipped with a screen. Set your screen brightness to 50% or less and your phone will drain slower. You can adjust the screen brightness by lowering the notification shade: this can be done by swiping two fingers across the screen (sometimes one is enough). The status bar will open and the option to change the brightness will open; you can do the same by going through the directory: “Settings” “Screen” “Brightness”. And while you're there, you need to turn off "Auto Brightness" (which is also called "Adaptive Brightness" in the latest version of Android 5.0 Lollipop).
Another important option in the display settings is that you can change the screen's "sleep" time. That is, the amount of time the screen will spend waiting for your commands before dimming and turning off a second later. Typically, the default interval is 30 seconds, but we recommend lowering it (to 15 seconds or less).
2. Identify the gluttony of some applications.
Suspended applications are those programs that are "minimized" but not completely closed, and they may continue to consume a lot of power without your knowledge. Luckily, Android has a built-in battery monitor. Go to “Settings” “Battery” and you can see which applications are the most power hungry. Now you know exactly which apps to avoid using if you're going to be outside the house all day. I would like to note that not all applications “burn out” the battery. For example, the application for recording calls and telephone conversations Arkyver, here is about it http://arkyver.com/ru/Android, is designed taking into account minimal energy consumption.
3. Enable energy saving mode.
Not all Android smartphones have a power saving function, but if you own phones from Samsung, Sony, Motorol and HTC, then they probably have the option to enable this mode, and you can turn it on when your battery charge is rapidly decreasing. On some Android phones, the power saver can be set to automatically start when the battery level drops below a certain percentage.
If your smartphone runs on Android 5.0 Lollipop. then there is a built-in energy-saving mode that can save you more than 90 additional minutes. You can get to it by going to “Settings” “Battery” “Battery Saving” (in the quick menu it’s the top right icon).
4. Disable NFC and Bluetooth.
Bluetooth is usually disabled by default, but NFC may work. We've tested many new Android smartphones and found that the only source of hidden power drain is background NFC. With the help of NFC, smartphones running Android communicate with objects with one touch, just like Bluetooth headsets and digital cameras. But just like Bluetooth, you need to enable this option only when it is needed. Some Android smartphones have a special NFC icon on the notification shade.
If your phone does not have it, you can turn NFC on or off by going to “Settings” “ Wireless network» "NFC Technologies".
5. Use dark “wallpapers” on your desktop.
There are two main types of displays for smartphones: LCD (LCD) and AMOLED. LCD displays use a backlight system that illuminates every pixel on the screen. However, AMOLED displays are created with pixels that emit light on their own. Each pixel, acquiring one color or another, glows and consumes energy accordingly. And the pixel that remains black does not light up and is not powered by battery power. If your phone has an AMOLED or SuperAMOLED screen (and, for example, most Samsung smartphones do), then you can set a dark or even black wallpaper on your desktop to make your device more energy efficient.
6. Turn off location detection (GPS).
Many apps, such as Google Maps, Swarm, and Yelp, use geolocation to provide accurate data about your location, but if you use apps with this feature rarely or sparingly, it's wise to leave GPS inactive. Some smartphones have a GPS deactivation icon - also called "location" in Lollipop - in the quick settings menu. Be that as it may, you can disable the transfer of geodata by going to “Settings” “Location”.
7. Disable unnecessary features.
There are some differences in the functionality of different gadgets on the Android system. And if your device is equipped with such stupid functions as “tracking the direction of your gaze” or “air control”, which, for example, the Galaxy S4 has, then go ahead! It's time to deactivate them.
Surely you will never use them, and they will take up battery power while in the background. Typically, options to turn them on and off are located in the settings of the applications themselves.
8. Disable vibration and optional sound alerts.
The haptic response, or vibration, that occurs when you interact with a smartphone's touch display is wonderful. I love the tactile sensation of touching a device that creates vibration feedback. But you have to pay for this pleasure with significantly increasing battery consumption.
Turn off energy-eating vibration by going to Settings Sound and notifications Other sounds. And there you can turn off “Vibration”, and, of course, “Key sound”, “Screen tap sound”, “Screen lock sound”, “Vibration response” - by turning off all this, you will be able to save the remaining battery charge in the event of, for example , emergency, when the smartphone is just about to run out.
9. Set the minimum number of widgets.
Widgets are a great way to grab all the important information with one quick glance at your home screen, or give you easy access to control keys for something like a music app. But for the sake of your battery life, turn off widgets that don't get your attention often. You can eliminate widgets by long-pressing and holding them, then dragging them to the “delete area” (sometimes it looks like a trash can symbol).
10. Cut off unnecessary animation effects.
Did you know that beautiful animation effects and graceful transitions consume power on your phone? Good news: you can disable them and add battery life if you enable the hidden settings: “For Developers”. Go to Settings > About Phone, then scroll down to Build Number and tap here 7 times.
Go back by clicking the back button and you will see the Developer section that was missing before. Once in, scroll down to “Window: Scale”, “Transition: Scale” and “Animation Speed”. Disable these three configurations and voila: your smartphone battery will start to hold a charge a little longer (and perhaps your phone will become faster). By the way, a reboot may be required for these changes to take effect.
