How to check for battery-draining apps on Android
Most phones have graphical data or lists that display every app that’s used your battery within a specific period. Below, we show some examples of how to find these graphs and data.
How to find your battery usage by app on Samsung
Navigating the battery settings fromBatteryshows a list of Android apps and their associated battery-use percentage (since the last full charge) within a period. In this example, we use a Samsung phone operating on One UI 6.1 (based on Android 14). The steps should be similar if you’re on another version.
You can view a battery usage graph since the last full charge or seven days. The graph displays the battery consumption data from 12 am to 12 pm each day (in a recorded seven-day period). The salmon pink shows when apps use the battery.

The graph bars show your battery usage by date and time. If you see an unusual spike outside your normal app usage, it might signal that a recent app’s update or installation might be behaving abnormally on your phone, but in most cases, it’s tied to activity.
The Battery usage graph does not record app usage while charging.

How to find your battery usage by app on Google Pixel
You can view the battery usage by app on a Google Pixel. You can also view details on the background time by tapping on an app. In this example, we use a Google Pixel onAndroid 15. If you’re using an older version, the steps should be similar.
How to find your battery usage by app on OnePlus
you’re able to view the battery usage details on a OnePlus phone by visiting the battery menu. It will break down the apps that use your battery in 24 hours. If you’re running OxygenOS 14, you can also optimize battery usage on theBattery usage detailspage; selecting it will allow you to close battery-draining apps to extend battery life. Our screenshots use a OnePlus device on OxygenOS 14 (based on Android 14).

How to check for battery-draining apps on iPhone
Apple also has a built-in function that allows users to view battery usage by app. We outline the steps for finding it. We used an iPhone running iOS 18; earlier versions since iOS 16 should have it, too.
It’s a common myth that apps running in the background are the reason your battery looks worse for wear. That’s not true. Most of the apps are not actually “running” in the background. They become suspended after closing (moving away from the app) or after completing tasks (such as syncing). It takes more energy from your iPhone to load up the app than to resume or unsuspend it.

How to save your battery on mobile
Slowing down battery consumption might be the key to getting through your day. So it’s time to take matters into your hands by activating power-saving mode andforce-stopping some appsfrom running rogue on your Android phone. Get started using the steps below.
How to force stop an app
Third-party apps running in the background (constantly) will deter your battery. Sometimes, those apps are not well-optimized for phones. If you’re continually force-closing an app to avoid battery drain, consider uninstalling those apps. Below, we show you how to force stop an app as a temporary measure to ensure your device remains in shape. The screenshots were taken from a Samsung phone on One UI 6.1 since there’s no easy shortcut to force stop an app on the battery usage page.
You can also force stop an app by tapping on the app name underBattery usage detailsandBattery usage since last full chargefor OnePlus and Google Pixel devices.

If nothing changes and force-stopping an app doesn’t prevent the app from reaching double-digit numbers (with respect to battery consumption) on your phone, do a fresh restart. When all else fails, it may be time to retire that app and report this issue to the developer.
Activating low power mode or power-saving mode
Running your device on power-saving mode should be a last resort when trying to save your battery. Turning on this mode reduces the power your device needs to run. This includes closing apps, turning off certain functions (like GPS and background syncing), and reducing your phone’s brightness. You’ll lose performance and activity, but in exchange, you can extend your battery’s life until you can charge it.
To turn on power-saving mode, openSettings>Battery,then toggle onPower saving.
Fixing a device’s battery health
Monitoring how apps affect your phone’s battery is only one step of the way. After discovering the battery-draining culprits, it’s time to take action. Most phones include options toprolong battery life. You can enable power-saving mode or customize your app usage and battery settings. Otherwise, if apps are not the issue, it could be the battery, which means it might be time toreplace your device’s battery.
