How To Fix iPhone Battery Drain Issue After iOS 13.5 Update

Time Needed : 10 minutes

Fortunately, it appears like the problem is not really that serious and is fixable at the user level. With that said, here are the things you need to do:

1. Disable the Background App Refresh

   Many users claimed that this method has helped in improving the battery life in an iPhone that runs the iOS 13.5. This will prevent apps from using your internet connection when idle. It means that only apps that you use will be able to refresh. 
   
   1. To do this, launch Settings from the Home screen. 
   2. Find and tap General. 
   3. Tap Background app refresh. 
   4. Tap Background app refresh at the top of the screen. 
   5. Choose Off to disable it.
   

2. Turn Off Location Services

   The next thing you will have to disable are the location services. There are a lot of apps and services on your iPhone that require you to have access to your location, and while it may be beneficial, these services often drain the battery faster. 
   
   1. Go back to the Settings page. 
   2. Scroll down a little bit, and then tap Privacy. 
   3. Tap Location Services. 
   4. Now tap the switch next to Location Services to disable it. 
   
   These two procedures are often enough to improve the battery life of your iPhone. However, if the battery continues to drain quicker than before, then try the next solution.
   

3. Reset All Settings

   iPhone users who didn’t have success improving the battery life of their device resorted to bringing the settings back to default configuration. This procedure is safe but has been proven effective against this problem. This is how it is done: 
   
   1. From the Home screen, tap Settings. 
   2. Find and tap General. 
   3. Scroll down to the bottom of the screen, and then touch Reset. 
   4. Touch Reset All Settings. 
   5. If prompted, enter your security lock. 
   6. Tap Reset All Settings at the bottom of the screen, and then tap Reset All Settings again to confirm. 
   
   Your iPhone will reboot after this, once it has finished rebooting, try to use the phone as you normally would to see if it still drains the battery quickly.
   

4. Factory Reset Your iPhone

   If the previous solutions fail to fix the problem and your iPhone still drains the battery quickly, then you have no other option but to reset your device.
