iPhone 17 pro unexpectedly Over Heating and Battery Drain

Today on October 21,2026 Iphone 17 Pro was very hot and battery drain from 100% to 56% within a hour. I did nothing special with the phone today and right now I am updating my phone to ios beta 27.2 RC to see if this will fix my problem.

But the phone never ever had problems like this and out of the blue this morning this happens. What do you think this cause is?

Many times a Force Restart is all that is needed if you are experiencing a stuck process that is running on your phone. If you see it happening again, I would try this.

  • Press and quickly release Volume Up
  • Press and quickly release Volume Down
  • Press and HOLD the Side Button until the Apple logo appears. This may take up to 15 seconds while holding the side button before you see the Apple logo and you have to ignore anything else on the Screen including the prompt to Slide to Power Off. We have seen where users see that prompt and think that is performing the Force Restart, but it is not.


I would not recommend turning off Background App Refresh as a means to reduce battery draining. It really has very little effect and does not stop background processes like some believe. It is only for updating the UI of an app so that is not done when you launch the app, but all the background processes initiated by the app, that will cause battery drain, still proceed like they always have.

Usually a specific app is the culprit of the problem you are describing. If you go to settings<battery there should be a pop up that shows how much percentage each app uses. If for example TikTok is the culprit, you would go to Background app refresh in settings and turn off TikTok’s option. If you have further problems I would recommend calling apple or bring the phone in for them to look at.

You would have needed to look at your Battery Usage in Settings to see what was using the battery.


Updating to the beta RC is still a risk as they are not always the same build number as the Release Version when it finally ships. There is no support for the beta software, so if you are looking for help after installed, you would need to remove it first.

After doing the update, everything is running normal again.

There were no battery draining apps running in my background at all. Plus the phone while charging via cable had a struggle charging to at least 60% from 54% within 45m of charging.

I don't have a answer why unexpectedly this happened, but as I mentioned doing that Particular update seemed to have resolved the issue.
