7 Steps to Fix Battery Draining so Fast Android

To stop the phone battery from draining fast, you can first try some recommended troubleshooting steps. And, if a user’s battery is still draining quickly, you can try to check if the software issues caused the battery problems.

Step 1. Check Battery Usage of Phone Apps

In most versions of Android phones, open your phone’s Settings > Battery > Go to Battery usage > Choose Show full device usage. Here you can view what app is killing your phone’s battery most, including active and background duration. So you can restrict apps with high battery use by checking battery usage. Normally, the apps consuming a lot of power are what you used more often. However, if there are apps that not in use, you can try to uninstall or limit their usage.

To Limit Background Usage:

First, you can enable deep sleeping apps, which will never run in the background, they will only work when you open them. 

Besides, you can turn off auto-run to stop apps from running automatically to set background usage limits and improve your device’s performance.

To Reduce Lock-out Time:

You can set a shorter screen timeout to fix the battery drain fast: Press the Menu button > Tap Settings > Touch Screen/Display > Tap Timeout/Screen Timeout > Then select a shorter time period.

To Uninstall the Apps that Draining Battery:

Uninstall the apps that eat up too much power and the app that you don’t use often.

  • Delete the app via Settings: Open the Settings > Tap on Apps/Application manager  > Find the app you want to delete > Select it and click the Uninstall button.
  • Delete the app via Google Play Store: Launch the Google Play Store > Click Settings > Tap on My apps & games and Installed > Select the app you want to delete and click the Uninstall button.

Step 2. Switch Off the Auto-Brightness Setting

Many smartphones come with a feature called Auto-Brightness, in which your Android phone will automatically set the brightness level by detecting the light condition. So you can try to turn off the Auto-Brightness and keep it slow.

Step 3. Turn Off Unimportant Notifications

It seems like every app will automatically demand to send notifications on your Android phone, but actually, there are some notifications that are useless. Just go to Settings > Apps and then uncheck “Show Notifications” in these apps.

Step 4. Disable Connections Manually on Android

If you enable the Wi-Fi, Bluetooth, and GPS service all the time, then they will eat up your battery very soon. You can open them when you need to use them and this will save much battery on your Android device.

Step 5. Shorten the Screen Timeout on Android

The screen timeout or sleep setting determines how long your display will stay awake after it’s been engaged with, so it’s totally wasting battery if your screen remains on while you’re not using it. Just set it to the shortest time. Besides, to save battery life and decrease the time the screen on, try not to watch videos for a long time, play graphics-heavy games, or use the camera too much.

Step 6. Check the Software Glitches

If you’ve tried to choose settings that use less battery but the battery draining problem still exists, you need to check if the problem was caused by software glitches. Try to reboot your Android phone first, and you can check the latest Android updates on your phone.

The best way to improve your smartphone battery is to charge as much as needed cause it’s really harmful to let the battery go from completely full to completely empty. So, it’s better to charge your phone fully overnight and don’t use it when charging.

And it’s best to charge your phone using the power adapter that came with your phone, so the battery can be more healthy.
