In the past week my 2.5 year old Sony Xperia 1 iv has started shutting down at 20% battery remaining.
It does this in a few different ways.
Sometimes it gets down to 20% battery and just beeps, but them immediately says 'shutting down'.
Other times it gets down to 20% then a few seconds later drops to 9% and then immediately shuts down.
A few times I have seen this happen when it manages to get down to as low as 14%. But still the same result of immediate shut down.
I have tried running in safe mode but it shuts down at 17% when I try that.
It's weird that it's such a sudden drop. And it hasn't happened gradually over time.
I've disabled various Android apps to see if any are causing this behaviour, but I've had no luck so far diagnosing the issue.
Are any other Xperia 1 iv users seeing this issue too?
Any advice to fix this would be great.
Thanks
