If your phone’s battery seems to be running out much faster than it normally does, an app could be using more power than expected. This can happen while you are actively using an app or when it continues to perform tasks in the background.
The good news is that you usually do not need a separate battery-monitoring app to find the cause. Android phones and iPhones have built-in settings that show how much battery different apps have consumed.
Here’s how you can check your phone and understand what the battery information means.

Check Battery Usage on Android
Android provides a battery section where you can see which apps have used the most power. The names and locations of some options can differ depending on your phone manufacturer and Android version.
To check battery usage:
- Open the Settings app.
- Tap Battery.
- Look for Battery usage, Battery usage by app, or a similar option.
- Review the list of apps shown on the screen.
The phone may display apps according to their battery consumption. Some devices also show the percentage of battery used by each application.
If you notice an app using a large amount of power, consider whether you have been using it frequently. An app that you use for several hours can naturally appear near the top of the list.
Look for Apps Using Battery in the Background
An app does not always need to be open on your screen to consume battery. Some apps perform tasks in the background, such as syncing information, checking for updates or sending notifications.
This is normal for many applications, but excessive background activity can contribute to faster battery drain.
If an app you rarely use is showing unusually high battery consumption, open its battery settings and check whether your phone provides options for controlling background activity.
The available controls depend on the device and Android version.
How to Check Battery Usage on iPhone
iPhone users can also see battery activity directly from the Settings app. There is no need to install another application for basic battery monitoring.
Follow these steps:
- Open Settings.
- Tap Battery.
- Scroll through the battery usage information.
- Check the apps listed in the battery activity section.
Depending on your iPhone and iOS version, you may be able to view battery activity over different periods. This can help you compare recent usage and identify apps that have been consuming more power.
Does High Battery Usage Mean an App Is Bad?
Not necessarily.
An app appearing at the top of your battery list does not automatically mean that something is wrong with it. The amount of battery an app uses often depends on what you are doing with it.
For example, watching videos for a long time can use a noticeable amount of battery because the screen remains active and the phone has to continuously process and stream content.
Navigation apps can also consume more power because they may use GPS, mobile data and the display while you are traveling.
Instead of focusing only on which app uses the most battery, look for unexpected usage.
If you normally use an app for only a few minutes but it repeatedly consumes a large amount of battery, it may be worth checking its settings.
Simple Ways to Reduce Battery Drain
Once you identify an app that is using more battery than expected, you can try a few simple solutions.
Limit Background Activity
Some Android phones allow you to control how much battery an app can use while running in the background.
Restricting background activity can reduce unnecessary power consumption, but it may also affect features such as notifications, syncing or other background functions.
For this reason, it is better to adjust these settings only for apps where background activity is not important to you.
Review Location Permissions
Apps that frequently use your location may consume additional battery.
Go through your phone’s app permissions and check which applications have access to your location. If an app does not need location access for its main function, consider changing its permission.
The exact permission options can vary between Android and iPhone.
Keep Your Apps Updated
Developers regularly release app updates that can include bug fixes, performance improvements and compatibility changes.
If an app suddenly starts using much more battery than usual, check the Google Play Store or App Store for an available update.
Keeping your phone’s operating system updated can also be helpful.
Remove Apps You No Longer Need
Unused apps do not need to remain installed forever. If you have applications that you no longer use, uninstalling them can reduce unnecessary background activity and free up some storage.
Before removing an app, make sure you do not need any locally stored information associated with it.
Do You Need a Battery-Saving App?
For basic battery monitoring, usually not.
Android and iPhone already include tools that show battery usage by app. These built-in features are generally the best place to start because they are part of the operating system and do not require installing another application.
Before downloading a third-party battery optimizer, check the battery settings already available on your phone.
When Should You Investigate Further?
Battery usage can change from one day to another. Gaming, video streaming, high screen brightness, GPS, mobile data and poor network conditions can all affect how quickly your battery level drops.
Because of this, one unusual day does not necessarily indicate a problem.
However, if your phone suddenly begins losing battery much faster than before and the same app repeatedly appears high on the battery-usage list despite limited use, it is worth investigating.
You can start by checking the app’s permissions, updating it and reviewing its background battery settings. If the problem continues, removing and reinstalling the app may also be worth considering, depending on the situation.

Final Thoughts
Checking battery usage is a simple way to understand where your phone’s power is going. Both Android and iPhone provide built-in tools that can show which applications are consuming battery.
Instead of immediately downloading a battery-optimization app, start with your phone’s own settings. A quick look at the battery usage list may reveal an app that is using more power than you expected.
Once you know what is causing the extra consumption, you can decide whether changing a setting, updating the app or removing it is the right solution.
