Battery draining fast and random crashes.
It's taken me a couple of days to register something not quite right.
I first noticed the device 'crashing' during use. The Motorola splash screen appearing, and shortly after having to swipe to access to use the device again.
I'm now seeing rapid battery drainage (from full to 40% in less than 3 hours), and projected full drainage to be far less than half a day (6ish hours) even though I've not used the device.
When looking at battery usage I'm not seeing any app use of the battery except Screen, Mobile network.
I've restarted the device, it continues to rapid drain.
I removed the obvious candidate (AV software - Sophos Intercept - to verify it wasn't background scans etc) but this has made no difference either to drainage or random crashing.
I've tried 'recalibration' method, full charge/power off/leave 1hr extra etc.
I've restarted in safe mode, and the rapid drain did not occur in 2 hours of being in safe mode.
After rebooting from safe mode, the battery stayed 99-100% for almost an hour, then is suddenly draining rapidly again!
The device is running Android 13, the last security update was December.
This may have been happening for longer than the past couple of days but it's only in these last 2 days that I've noticed the random crashes during the day though I have recalled the need to swipe for access in the morning suggesting the device may have crashed during the night (I use the fingerprint unlock feature normally).
When the device random crashes I have to swipe for access (I don't need to unlock the SIM - so it appears almost like a soft reboot?)
Without accurate battery usage info I cannot tell which app (if any is draining the battery) or is the OS? I've had a couple of "System UI" freezes during trying to navigate the settings options also.
What do I try next? Other than removing apps one by one that've been updated in the previous week?
Note: I've removed apps I don't use often, and have quickly read recent reviews of the main apps I use that have been updated recently to see if anyone else has reported bad app battery usage/memory leaks etc.
I haven't installed any new apps in this period so I cannot easily point a finger to a culprit and say "this is what's changed this week!".
Any ideas please?
