Try this:charge the phone to 100%(let it charge for 1 hour),remove the battery and put it back in.Do not turn on the phone.

Download SUS and repair:

Does the phone even disconnects when you follow the process in Update Service beavuse the phone shall be turned off during the whole update procedure. 

If you can't update/repair the phone software using Update Service, I suggest that you have your phone examined by a service center. Please contact your local Xperia support team for more information:

I'm having the same issue too. my phone shut down when battery is 70%, I just downloaded the update file but I need more assitance; Do I need to backup all the information in my phone and then I can run the update file? Does the phone needs to be turn off? Do I have to turn it off, let it charge up to 100%, disconcect, remove the battery and the run the update? Someone can explain me how to do this without damaging my phone? 

Please help, I really need more assitance. 

Thanks!

Hi,

I have a very similar issue to this. The battery indicator shows normal usage, then suddenly the phone indicates battery remaining 1% and shuts down unless I can get it plugged in within a couple of seconds. If I plug it in, the battery level almost immediately goes back up to the level it was at before the nosedive (say battery was showing 60%, it goes to 1% then back to 60% immediately the charger is plugged in.

I have an almost new spare battery which behaves the same way, so it's not a battery issue.

I did a complete wipe & reinstall last night using SUS, hoping this might clear it. However, same issue this morning. I managed to get it onto the charger and take a screenshot of the battery usage monitor, see below :-

The ~30mins usage was me re-configuring phone settings after the reinstall, hence the high display usage. The graph clearly shows a normal battery decline before the sudden nosedive, and also shows it returning immediately to the previous level once plugged in. After a few minutes I unplugged the phone - the 98% charge shown on the graph above remained for 5mins or so then went back to 1% and shutdown.

If I restart the phone without plugging in, the phone boots and initially shows a normal battery level (as it was before the nosedive) for a few minutes, then goes back to 1% and shuts down.

Can anyone explain this? Is there a fix or am I looking for a new phone?

Thanks

Richard.
