🚫 Your Device Might Face Performance Problems
The biggest issue with developer betas, and betas in general, is that your device might get hit pretty hard in a bad way.
Your device might experience performance issues for no apparent reason. Granted, this might be more likely in older devices, but since the beta isn’t perfect yet, new devices might suffer from it too.
A lot of people who have installed the iOS 16 developer beta haven’t experienced any issues with performance, but some of them have reported that their iPhones have overheated these last few days. That’s not something you want for your iPhone, especially if it’s fairly new.
