How to Downgrade iOS 17.0.3 without Data Loss
iPhone 15 users, specifically iPhone 15 Pro Max users, have been suffering from iPhone overheating issues since they got the device in September. From Reddit, you can see many people were complaining about it. As a fix, Apple rushed out iOS 17.0.3 to fix the overheating issue caused by fast charging.
Tested by ZDNET, it is said the overheating issue while using fast charging is resolved, as the screenshot below shows. It’s much cooler than before.
However, the bad news is that some users have reported that after installing the iOS 17.0.3 update when their phone's battery level is at 68%, many warnings say it has stopped charging due to excessive temperature. What’s worse, some users find that iPhone 15 will automatically turn off for hours for no reason, and users have to get it out of sleep manually, and some iPhone 15 reboot after hours of turning off.
When facing the overheating issue for iPhone 15 Pro and iPhone 15 Pro Max, there are two solutions: one is downgrading to iOS 17.0.2 if the overheating occurs after you upgrade to iOS 17.0.3. Another is waiting for the imminent iOS 17.1.
