I have had no problem indicating a hardware problem on my 7+ but after installing 11.2.1 I have a freeze and restart loop whenever I have wifi activated. I'm mildly skeptical about this simply being a hardware problem.
I have similar issue since early iOS 11 and still have not been fixed until now. I’ve searched around and this is a common issue for 5S. It is supposedly a software issue, unless you have “panic” report on your analytics.
The only thing that you can do right now is turn on low-power mode, since it helps with reducing with the reboots. Not even a full restore can help this from my experiences and other’s experience. 😟
You have corrupt data in your backup. Restore using iTunes and set up as a new account.
I set it up as a new iphone. I didnt use backup..only contacts and photos from icloud.
Then your phone has a hardware problem.
It worked completly fine since the ios 11.2.1 update. After installed that piece of crap i instantly got a restart..
Iphone 5s keeps restarting after updating ios 11.2.1! What to do?
