Hey everyone! I've been having this issue with my iPhone 12 where it unexpectedly shuts down and restarts every morning at around 4 AM, especially when it's charging. Does anyone have any idea what might be causing this?

I totally relate! My iPad Pro has been doing this too — it restarts around the same time in the early morning. I spoke to Apple support a while back, but they couldn't find anything wrong in the diagnostics. It's annoying because apps like Audible need to be reopened, but I just got used to it. Just keep in mind, it’s not critical, just a bit irritating!
It sounds like it might be related to some background processes that kick in while your phone is charging overnight. iPhones often run maintenance tasks like checking crash logs or thermal tests at early hours. Here are a couple of things to try:
- Check your battery health in the settings. If it's dropping, it could lead to restarts under load.
- Switch out your charger and cable to rule out potential power issues.
- You might want to turn off "Optimized Battery Charging" for a bit and see if that helps.
- Lastly, make sure you’ve updated to the latest iOS version; sometimes, these bugs get fixed in updates.
It's usually not something serious, but if it keeps happening, doing a backup and then a restore could help clear up the glitch.
