Which Android game is draining your battery

This is how you can tell which apps are draining your battery on an Android phone or tablet

If your Android phone's battery always feels a little low, then you can find out exactly where that power is going. The battery used since the last charge is displayed on the "Battery" screen of Android, from apps to system services to hardware devices.

How to access the battery screen

Open the Settings app in your app drawer, expand the “Device” section and then tap on the “Battery” option.

You can also open the Quick Settings section in the notification window and long-press the battery icon (or the battery saver on Oreo devices) to go directly to this screen.

The battery screen only shows the battery usage since the last full charge. If you've just charged your phone or tablet, this won't be very helpful. Ideally, you should check this screen when your device's battery is low to get an idea of ​​which apps, hardware components, and system services have actually drained the battery since your last charge.

On older versions of Android (Nougat and (earlier)) you get a table of battery discharge information. Just below you can see what is draining the battery. On Oreo and later, several battery settings are shown above the list so you have to scroll down to get to display them.

On Samsung devices, you must tap the "Battery Usage" button in the battery menu to view this list.

Assuming your device has been running for a long time, it will give you an accurate picture of how much battery power has been used and when it happened. You can tap an app or service to view more detailed information.

Android actually gathers a lot more battery usage information that is displayed on the Battery Settings screen. Previously, it was possible for an app like Better Battery Stats to request BATTERY_STATS permission and access this information. You can then view more detailed battery statistics. For example, you can view information about wakelocks or view battery usage for periods of time that are not shown on the Battery screen.

Unfortunately, Google removed this permission from Android and apps can no longer display it. If you've rooted your Android device, you can still install an app like Better Battery Stats to see more detailed information about battery usage. However, without rooting you will stick with the information on Android's built-in battery screen as these apps simply cannot see this data.

Nevertheless, there are a few more options for more informative battery statistics on Android. Our preferred app to get detailed information about your battery (without rooting) is AccuBattery. Not only does it tell you which apps are using the most battery, but it also gives you a detailed look at your battery health. This is one of those apps that just keeps getting better and more useful over time. The more you use them, the more you will love them.

What are all of these hardware and system services?

On Android Nougat and below, Hardware and Operating System information appears in this list along with any apps that have expired battery life. However, in Oreo, this additional information is separated by default. To find it, you need to tap the menu button in the top right corner and then select the option "Show full device usage". This way you can see that the hardware components and operating system services are consuming the battery. Note, however, that this is a separate list and doesn't include apps that use battery.

You can get more information about a hardware component or service by tapping it. Apps are self-explanatory - they use battery power when they are open and some may also use battery when they are running in the background. Below are all of the non-app items in the list:

  • screen: This is the amount of power consumed by the screen and its backlight. Your screen always uses a significant amount of power. You can reduce usage a bit by lowering the screen brightness and configuring Android to turn off the screen when you are not using it.
  • Wireless Internet access: This shows the power of the device's WiFi radio used by your computer. It always uses some power when you are connected to Wi-Fi and even when you are not connected as it looks for available connections. You can save some power by turning off WI-Fi when you are not using a Wi-Fi network.
  • Cell standby: Assuming you are using a device with a cellular connection, that cellular device is always powered. Having a weak cellular signal can result in higher power consumption.
  • Android OS: This way, all of the battery power is billed to the underlying Android operating system that manages your running processes, communicates with your hardware, and does all of those low-level things.
  • Android system: Despite the name, this is separate from the Android operating system itself. It represents battery power used by things like the Settings app, input devices, and various other system services. You can reduce battery consumption by turning on battery saver mode.

  • Google Play Services: This includes a variety of services including Google Play Services, the Google Account Manager, the Google Services Framework, and the Google Backup Transport. This is just another package of services used by your Android device. Battery saver mode can also reduce the power consumption of these background processes.
  • Phone idle or tablet idle: Your Android device consumes a certain amount of power just because it is turned on, even if it is completely inactive in sleep mode.
  • user: If you have set up multiple user accounts on your Android phone or tablet, a separate "User" item is displayed here for each user. This will help you understand how much other user accounts have contributed to your battery usage.

You probably already know that you can turn the screen brightness down and turn off Wi-Fi and Bluetooth when you're not using them. However, there is a lot more you can do beyond these simple tricks.

If the battery screen says an app is in use if you're using a lot of battery power, you may want to remove or replace it. Apps will definitely show up on your battery screen when you actually use them. However, some apps are more powerful than others. For example, a demanding 3D game uses more battery power than the average app. Some apps also run in the background and consume power even when you are not actively using them. There is no way to completely prevent apps from running in the background. However, you may be able to turn off background operations in an app's settings. If not, you can uninstall or disable the app and use an alternative. For example, instead of the power hungry Facebook app, you can use Facebook's battery-friendly mobile website.

If your phone is running Android Oreo, it's running, so find out if an app is running in the background and draining your battery. If you don't like this feature, you can easily turn it off. However, it is also very handy for keeping an eye on apps that are no longer working.

Other Android features can also help you save performance. Power saving mode puts your device in a more conservative state where less background work is allowed, and you can have the phone wake up for you automatically. Doze helps you conserve energy when you are not using or moving your phone. You can also make Doze even more powerful.

The battery screen shows you where your battery is located, it is up to you to do something with this information. This is a good starting point if you want to start saving energy. Unfortunately, Google only has limited access to more detailed information on battery usage. However, the included battery screen should be more than enough information for Android users who are not geeks. It's just nice to have long-term access to information, especially if you've recently charged your device. For example, the battery consumption data for the last 24 hours would be helpful.

Similar features are available on Microsoft Windows 10, Apple's iPhones and iPads, and Mac OS X. You can see exactly what is using battery power and make informed decisions to extend battery life.
