Iphone 12 battery level suddenly drops from 50% to 25% !!!!

Recently, my iphone 12 (128 GB) battery charge drops from 50% to about 25%. It seems this happened after iOS 17.1 update. Although, I updated it to the newest iOS (17.3.1), but it still remains.

It is really annoying and I can not find a way to fix it yet.

Please help me with this if u know.

thanks

iPhone 12, iOS 17

The battery looks to be in good order.

Try and Force Restart your iPhone EXACTLY as shown below and see whether that resolves the issue:

  • Press and quickly release Volume UP button
  • Press and quickly release Volume DOWN button
  • Press and Hold the SIDE button until an Apple logo appears and then release the Side button (Can take up to 20 seconds. (DO NOT release Side Button when invited to Slide Power OFF). 


After the above action has been successfully executed, then monitor your iPhone to see whether the issue persists.

Double check the battery health. You may have a poor battery condition which cannot provide sufficient power for peak performance. What is the Battery Health of your iPhone? Open Settings  Battery  Battery Health and let us know which percentage you see for Maximum Capacity. Also note what is written under Peak Performance. If your battery's Maximum Capacity shows a value of 80% or less, then it has gone through its lifecycle and therefore should be replaced, according to Apple.
