I have an iPhone 14, 10 months old have been having multiple issues since updating to iOS 17, the latest is overheating even when not doing anything on my phone, particularly with charging, only ever use Apple cables.
Anyway. Mine is still under warranty so had a lengthly call with AppleCare, who ran analytics on my phone which still has 99% battery health, software up to date. It’s not a phone issue. I know it is the software after reading everyone’s issues.
Befrie even considering looking into it. I was told I have to use a computer. My Mac book. To restore my phone, then manually download my phone without downloading off iCloud 🤦🏽♀️ but also got told to use my phone without downloading anything at all. To see if I had downloaded bugs when updating to the newest iOS 17.2.1
Slightly reluctant to wipe my entire phone 😅 as there is always risks of loosing data, as since the update my contacts etc don’t all save to iCloud with alls settings correct I’ve lost as lot of them. The lady on the phone couldn’t understand the issues.
Claimed I must have downloaded a bug. Not owning up to the fact iOS 17 has caused major issues for customers worked wide yet they are still using it and haven’t fixed it. They said by restoring off a computer it will wipe the software off and redownloaded again not just reset the old software as it would if you reset to factory setting off your phone
anyway hope this may help you. Straight from Apple cares mouth
