I have installed iOS 14 Beta 7 last week on my iPhone 8 Plus, and after 3 days, at some point before I went to bed my phone had 1% battery and plugged it in to charge. I've had iOS 14 Beta installed since it was launched and I've been testing Betas since iOS 6 as a member of the Developer Program. The next morning, the phone didn't start. I attempted to do a hardware reset but without any luck. After multiple attempts I left it for service at a partner service. Today, they kind to provided feedback on my issue: It seems that the phone is in a restart loop as it tries to boot. They tried to make it work with a different battery but with no success. The issue seems to be with the HDI integrated current checker - it returns: Device will not turn on. The software seems to be ok. Is anyone Apple willing to help me with this? Thanks, Ciprian
