The Latest update: Battery Overheating

The latest updates of what? iOS 18 or iOS 26?

Which version is causing an issue?

Information like this is really important. It's like saying, "My car has a problem." People are naturally going to ask what's wrong with your car. Just, please, provide more relevant information in future so we don't have to ask.

If it's iOS 26 Developer beta, then you must know that the betas include various processes that that are not present in the public releases. These processes run in the background to log things, record system issues etc.

In short, the betas run more processes than the final version runs, and it is expected that your phone will run more processes, which in turn means it may run hotter and your battery life may be adversely affected.

If you feel it's unusual, then feel free to raise an issue in the usual way, by raising a feedback report at: https://feedbackassistant.apple.com/ and post the FB number here. Remember to provide relevant information.

As an aside, regarding the tags you added to your post, is "Developer Forums" really relevant to your post? Are you saying there's an issue with the forums? No, you aren't, so please don't use the wrong tags.
