Xperia T keeps switching off and on since last update

[Aljasper]

Hi,

My Xperis T keeps switching off and on since the last scheduled update to Android 4.1.2.

I have tried overnight charging whilst phone is off but the situation keeps happening.

Any advice or assistance woud be helpful, especially from Sony Techs Support please.

Can I reverse the update?

Regards,

Alasdair

Yo buddy your text seems to make sense mate, please send me an email to Nickwi7979@Gmail.com as I would like it if you could elaborate on your resolve for the Sony lt30p problem of switching off....

I had the same problem. My only certain solution was exchange the battery. I think that software updates fried old battery.

Eventually (reluctantly) did the upgrade and my phone has switched itself off 6 times in the last 24 hours whether on charge on not. Am furious! Unreliable phone now so am forced to upgrade - I'll never have another Sony again

Sir, I'm literally having the same issue rn with the phone shutting down  below 50% soo it definitely has something to do with the manufacturer.
