The last few days my iPhone 7 (on iOS 14.3) has been repeatedly crashing and rebooting itself. I worked with a chat rep at Apple Support to force a reload of the update - didn't fix it. I removed and replaced the SIM card - didn't fix it. I checked analytics and removed an app that had multiple entries - didn't fix it. Analytics has LOTS of logs, but I don't know how to read them.
Anyone have any suggestions? Thanks!

In Settings>Battery>Battery Health, what's listed for Maximum Capacity?
If it's under 80%, you likely need a new battery.

If you're seeing that message about cellular, it's possible your phone has a hardware failure.
Your phone might fall under this: https://support.apple.com/iphone-7-no-service

Drat. Does anything in particular happen before the crash?
One thing I've done is to make sure I have a current backup, then set the phone up as new - not even signing in to my Apple ID - and seeing if that helps at all. If it's still crashing, then there's a hardware issue.

Hi, Lyssa - No, it's at 92%. I actually replaced the battery a year or so ago. <sigh>
Is there a message about battery condition? Sometimes batteries have failure modes other than loss of capacity. And did Apple replace the battery, so you know it was a good quality battery?
Definitely worth asking about. If it doesn't qualify for replacement through the program, you probably do need to plan to replace the phone in the near future.

No, I've had no message about the battery - yes I had Apple do the installation. When it reboots itself the message I was getting is that a cellular update failed - but there is no cellular update to install. When I manually reboot it finds the carrier - it's a little slow about it but it finds it. Now most of the time it just reboots without that message, but it has shown up a couple of times. Just saw your earlier message about setting up the phone as new. Guess I'll try that. I've tried about everything else. Thank you for taking so much time on my problem!

It's the only phone I have - fortunately, my husband also has a phone so we're not totally without. I'm going to try Lyssa's suggestion of setting it up as a new phone without my Apple ID and see what happens. I'm starting to think it's hardware and I need a new one.
You did it, Lyssa! It's a model A1660, which falls under the problem in the article. It's a hand-me-down from my daughter, so I don't know if it's more than 4 years old or not, but certainly worth checking into!
Thank you!!

iPhone 7 repeatedly crashing and rebooting - heavy battery usage
