iPhone 13 shuts down unexpectedly with high battery percentage

Title: iPhone 13 Keeps Shutting Down Even When Battery Is Above 90%




Hello Apple Community,




I am using an iPhone 13, and its Battery Health is currently at 70%.




The issue I am facing is that the iPhone randomly shuts down even when the battery level is above 90%. Sometimes it switches off without any warning, despite showing a high battery percentage.




I would like to know whether this issue is related to the degraded battery health, or if it could be caused by another hardware or software problem.




Could someone please guide me on whether I should get the battery replaced directly or have an Apple diagnostic test performed first?




Any advice or suggestions would be greatly appreciated.


Thank you.

Apple recommends that you replace the battery when the Battery Health dips under 80%. So, the battery should have been replaced 6-8 months ago or more.


You can find a list of authorized Apple service shops in your area to replace the battery by using the link just below:

Yes, you can ask the tech to run a diagnostic test if you want, but you already know what the results will be.


About $90-100 (U.S.)

In addition to the advice you're already been given, do NOT delay having the battery replaced. It is way past time to have the battery replaced and with every charge, you run the risk the battery could swell, destroying the phone without any possibility of being repaired. Not to mention it can become a fire hazard. Spend the money or trade it in towards a new iPhone. But do it as soon as you can.
