Hi there. My iPhone 14 Plus keeps rebooting every few minutes. Error code is 0x500000.
Can anyone shed some light on what this issue is and what I need to do to get it resolved

Hi Liza,
You were on the right track with error code . Here's the smoking gun from your panic log.
S.sensor array 0 - 4 is 0x0, 0x500000, 0x0, 0x0, 0x0
Alisha, who asked you about it previously, is the author of the best information we have on iPhone panic log errors. Here's what their wiki page has to say about yours.
iPhone SMC Panic Assertion Failed - iFixit
Sensor Array: 0x500000
Likely Issue: Battery **
**Replacing the battery will result in a warning message that the battery installed is not an OEM Apple battery, unless you use an Apple battery supplied by Apple's Self Service Repair program and run System Configuration.
The short story is your phone is having an issue talking to the battery. It scans its sensors every three minutes, so three minutes after booting it goes to check. In your case for some reason it can't talk to the chip on the battery so it reboots the phone in an attempt to recover. Of course this is a hardware failure, so once it comes back up an checks the sensors again, it sees that it can't talk to the battery so it reboots the phone... and just keeps doing it because despite how smart a computer can look, it's really stupid and will never ever realize that rebooting again won't help.
So the fix here is to replace your battery. If you buy a genuine Apple battery and have iOS 18 then you should be able to get rid of the "genuine parts" warning using the Repair Assistant; otherwise you'll either have to pay Apple to fix it or live with the warning.
Here's the iFixit guide showing you how to do that repair if you decide you want to tackle it yourself.

actually secondhand batteries would work as well. It's going to show as "used" in the parts and service history, but it won't have any compatibility issues.

Can you post the full panic, just so I now I've got it right? A screenshot. Or other. If you can?
