Xperia T charging issue

[JuKo19]

Hi all,

As some other people I have a charging issue with my Xperia T. I have read through the other posts, but found that they don't exactly match my issue, so here's what my problem is:

Yesterday my phone suddenly crashed with 17% battery left. I tried to switch it on, only got the typical melody for low battery and the phone did not turn on, tried one or two times more, same issue. I then connected my phone via USB cable to a wall socket. The red light came on and it looked like it was charging, I left it for half an hour or so, tried to switch it on, it did eventually, but battery showed 1%. Phone then kept charging, but seemed to stop when it reached 9%. I then switched it off, switched it on again (while still connected to charger) and it then displayed 27% charged. It then kept on charging until it reached 44% where it seemed to stop again. I once again switched it off and on, it then showed 69%. I left it connected to the charger over night, in the morning it still showed 69%. I switched it off and on again and then it charged up to almost 100%. Then I used my phone during the day and when it reached 49%, I wanted to charge it again. Charger was connected, phone was on, the red light kept turning on and off and the kept displaying either "charging" and the regarding percentage or "connect charger". When I switched it off and then on again, it showed 22% (when it had still been at 49% before!). At some point it decided to accept the charging and I got my phone charged up to 100%. At a later stage when it was down to 82% again, I tried to charge again (just to see what it does), it did not respond at all apart from flashing the red light once in a while, apparently attempting to charge.

I have tried different USB cables, different chargers, different sockets, no difference. I cleaned the mini USB port on my phone, there was a bit of dust in there, but that apparently didn't make any difference either.

Would exchanging the battery (probably 2-3 yrs old) for a new one help or does the issue seem to be with something else?

Thanks in advance for your help,

Julia

You could try repairing th ephone with PCC, if that doesn't work then a battery "might" solve the issue, hard to tell until you get your phone inspected by your local Xperia Care

PC Companion (PCC)

Bridge (for Mac)

Thanks for your answer.

I can't connect my phone to the PC I.e. it just won't recognise a phone being connected, so that rules trying that solution out.

I found out I can get my phone to charge by pressing the power button, holding it and then plugging the charging cable in, and keeping the power button pressed for a moment longer.

However, the battery seems to discharge way quicker than before. Even if I hardly do anything with my phone, it'll be down to 20 or 30% in less than 10h.

Does that give any more insight into what's happening with my phone?

Thanks,
Julia
