Battery Drain on iOS 26 and iOS 26.0.1.

I have already put that information in other places in this mega thread. iPhone 13 mini, iPad A16. Both running iOS 26.2 I used to troubleshoot computers for a living. There is trouble somewhere in the iOS 26 upgrade.

Under the post you replied to it shows where that person directed their post. For example, you responded to Jeff Donald who was asking the question to muzckl1 and pertains to a completely different issue and that person is not experiencing the same Charge Limit issue you are having.

As suggested previously, you should try charging your devices all night to see if the behavior changes. No one else on this megathread is experiencing the problem with the Charge Limit. As stated already, it is supposed to charge to 100% on occasion to maintain accurate reporting, so do not manually remove it from the charger before that time and give it the necessary time to update the battery settings while it is at 100%.

If not resolved that way, then schedule a service appointment at Apple. If it was a problem with iOS 26, then we would all be seeing it and also there were be tons of posts about it on this support site. The only posts found are those that did not realize it still needed charging to 100% at times and once they realized that and left their device alone it returns to the normal Charge Limit.

You also have the option to make a new post since your issue is not related to the battery drain issue reported here and this thread pertains to iOS 26.0.1 which is now outdated and not even signed by Apple to be used for an update.

are tons of posts about the battery issue. I have had Apple devices for so long now - I understand the charging behavior. THINGS ON APPLE'S SIDE OF THE EQUATION HAVE CHANGED.

None of the posts here on this page have anything to do with the Charge Limit issue you are reporting. Even using the Search option on this Support Site does not show anyone else with that issue where it has not been resolved by letting it charge to 100% like it is supposed to and then it returns to the Charge Limit.

You can say things have changed on Apple's side that affected the charge limit, but it only appears to be the case on your devices, which would not be true if it was a bug in the OS. How you want to proceed is up to you and have been given many options.

Please be aware that we're not trying to dismiss your issue; rather most users, including the senior level posters here, simply do not experience this issue, myself included.

That means there is something unique to your combination of apps and the way they interact with iOS that is causing this, which is made even more likely by the fact you experience this on both your iPad and iPhone; it's very likely the same misbehaving app is present on both causing the battery draw.

The key is until we can figure out which app that is and its vendor can fix it, this problem is likely to continue without mitigation.

I am currently (again) allowing the phone to charge to 100%, although I took a look at the screen and saw the message "14 min to 80%" followed by "2 min to 80%" and now it's charging past 80% on its way to 100. Again. I do think there's a possibility this is related to other issues with the battery performance and how the iOS interacts with the battery. Time will tell.

Given the fact that so much time has passed and the root cause still has not been identified yet - please tell me what you think about this action plan:

1) Perform clean install of iOS while iPhone is connected with cable to macOS.

2) Once installation is completed give it a week or at least 3-4 days till indexation is completed.

3) Go to the Setting and customize phone according to your preference. Afterwards test if battery performance has not changed (in case if issue is related to any specific setting that was changed).

4)Use phone for another week without installing any app.

5) If issue is not reproduced start adding 1-2 apps form AppStore and test for few days if battery performance has not decreased. Start with the one which is suspected the most (Meta apps).

6) Repeat 5 till issue is reproduced.

What does the Battery pane say is using your power?

Yes I have too on my 14 pro. It happened after I updated the software that changed everything on the phone

How much signal do you have? If it's only a single bar that's pretty much normal as it takes a lot of power to keep in contact with the tower at those signal levels.

Do you record the FaceTime calls? Are you on WiFi or cellular?

No recording. On WiFi. The question is: why does the battery keep being used by FaceTime long after the call is over?

Please help me update my iOS

Several charges later, it appears that the setting is being ignored altogether for both the iPad and the iPhone. It charges to 100% every time (unless I remember to check it and remove it around 80%)

I did that two weeks ago. Everything is fine. This 80% battery charge limit is being ignored on both the phone and the iPad (the iPad is new). Something is amiss that is not specific to my devices.

I stand corrected: both devices finally stopped charging at 80% one time recently. The phone showed “x min to 80%” but charged past that many times prior. The phone battery drain issue continues.
