iPhone 16 frequently exceeds 90% charge limit

Title: iPhone 16 Frequently Exceeds the 90% Charge Limit

Hi everyone,

I am using an iPhone 16 with the Charge Limit set to 90% under Settings > Battery > Charging. However, the battery frequently charges beyond the selected 90% limit, sometimes reaching 100%.

I understand that Apple has designed the iPhone to occasionally charge to 100% to maintain accurate battery charge-level estimates. However, this is happening much more frequently than I would expect.

I have already tried the troubleshooting steps and suggestions available in the Apple Community, but the issue persists.

My questions are:

  1. Is this behavior normal, or could it be related to an iOS software issue?
  2. Why does the iPhone frequently exceed the selected 90% charge limit instead of doing so only occasionally?
  3. Is there any recommended troubleshooting procedure to ensure that the charge limit works as expected?
  4. Has anyone with an iPhone 16 experienced the same issue and found a reliable solution?

I would appreciate suggestions from users who have experienced this issue, as well as any clarification from Apple Support.

Thank you.

It is normal and really doesn't affect battery longevity anyway.


Logically if you are worried about maximising capacity then limiting to 90% is counter productive.


I use optimised charging and charge to 100% every night.
