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

The motherboard is faulty so you need to get it replaced. Sony won't admit this is a problem with their phones even though it is.

Hi,

I have the same problem in the last 3 days,
The Phone switch off constantly if the battery charge is less that 50%.

I sent it to tecnical assistance, but the only think that they done was cleaning terminals and software reset (I have made that before, but ok)

But in my opinion this is: or a battery problem, or a battery management software problem.

PS: if the phone is connected to the charger, it dont switch off.

Hi

Your not alone, my phone was fine until the upgrade to 4.1.2 seems they never learn and rush upgrades out because other phone companys do upgrades. My Xperia T was fine since then, i did try and find out how many phones they have messed up and it seems about 5-10 customers of o2 have complained each day about this upgrade, they did say send the phone in, but that is not the solution its there upgrade.

Kind Regards

Hi,

My phone does the same thing, it was fine until you messed it up with your un-bug tested 4.1.2 was told i cant put my old version on there. I had a very good phone untill this upgrade, not very happy with this, plus the support has been very bad, all they say is send it in, but thats not they way to go. You have let down so many people with this problem o2 tell me about 5-10 people per day. So get your finger out Sony and either have a solution for backward software if there is problems with new upgrades, so it keeps the customer happy untill the new upgrade if there is problems like now, that you wont admit, by looking for ways out, and saying it must be other apps that you are using.

Waiting for a fix

I HAVE THE SOLUTION!!!!!!!!!!!!!

Video tutorial on take the battery out - http://www.youtube.com/watch?v=4BtXZiVLtWc

Buy the NEW battery on Amazon here - http://www.amazon.co.uk/Battery-Ericsson-Xperia-LT30p-1780mAh/dp/B00BOU86JC

EVERYONE LISTEN!!! Do not waste your time sending off your phone to your provider or manufacturer. I had this problem and it got to the point where my phone would even turn itself off whilst chargin. After looking at close to 100 different forums, websites etc on this problem and only seeing one comment of someone who said they bought a third party battery and it worked but nothing else said about it.
So, i found a battery for the Sony Xperia T LT30p (or more commonly know as the Sony Xperia T) on Amazon. I ordered it for about £16 and put it as 3-5 day delivery but go it next day so thats always good.
But then theres the problem of how to change the battery since you cant simply slide off the back of the phone. Well, i found a video showing how to take apart this exact phone , so i followed the video carefully where he shows how to remove the battery (you dont have to watch anything after this point) and removed the old bettery from my phone. then putting in the new battery i bought. The video does not show how to put the phone back together but it's common sense and very easy, simply reconnecting about 5 cable things (dont know what they're called) and putting the back of the phone back on.

After i did this, my touch screen did not work, but i soon found the fix for this, just hold down the unlock key and the volume up key at the same time until your phone vibrates, this is a reboot and after this, you phone should be back to normal.
As far as i know this is the only actual solution to this problem as it stands, sending it off to your provider or Sony usually comes back saying there was no fault (from what i have read)

The tools it shows in the video are not completely neccessary, i used a pen knife to undo the 1 screw that needs unscrewing to access the battery which is the screw for the whole phone case, then used the pen knife again to winch off the back casing, then to undo the cable things i used a pair of tweezers.

This is very simple and easy guys and i really hope this helps all of you!

I am really reluctant to pull my phone apart. Is SONY not going to do anything about this, eventually everyone who uses one of these phones will have this problem...even James Bond! Or is SONY just going to not care about existing customers until they buy an iPhone.

This obviously a software fault within the phone Sony so how about a fix... There is a lot of unhappy xperia t owners out here with this problem me included.. Mine only works now if it's constantly plugged in to the power socket... Please fix this problem...
