after upgrading my iPhone 11 with the new iOS 16 my phone has been heating up and battery running down very fast….any help please

After upgrading, the symptoms you describe may be normal until the entire OS, and all Applications have been updated. In my experience those symptoms may last for 24-48 hours.

If you still experience those problems after that time, it may also be beneficial to Restart your iPhone.

i’ve always restart my iphone but still the battery just keep draining so fast and the phone is just open from the box about 3 weeks ago and after the update it drain so fast.
