Re: Xperia S battery drops to 0 while on a call

Switch off your mobile

1st - both keys 5 seconds

it will turn on, again switch it off and then

2nd - both keys 10 seconds

3rd mobile already on

both keys 5  seconds

4th mobile on both keys 10 seconds

although 1st and 2nd are enough but 3 and 4 to do it for sure

Re: Xperia S battery drops to 0 while on a call

I have an Xperia P and probably the same problem. I was redirected here from that subforum.
Do I understand it correctly that you must:

1. Switch off phone

2. Press these buttons for 5 seconds

3. Press these buttons for 10 seconds

4. Switch on phone

5. Press these buttons for 5 seconds

6. Press these buttons for 10 seconds

How important is it do it in this order?

Since my problem is that in step 2 and 3 the phone switches on after pressing about 4 seconds. And in step 5 and 6 the phone resets itself after pressing about 4 seconds.

Thank you for your help

PS. Oh wait a minute, now that I post I see that there is a second page with this thread and I might see the anser now.

Re: Xperia S battery drops to 0 while on a call

Hi Nabeel,


I was having two probs: -


1) The phone shut down automatically. It just refused to switch on and stabilize. It switched on and shut down in a loop.

2) The phone was showing false battery %.


For the second prob, I tried your method and it worked. After that, for first prob, I repaired my phone using Sony Bridge for Mac and it actually reset my phone to initial stage rather repairing it.  After the repair, I faced the issue of shutting down once (just after the repair was complete). I haven't faced it again after that (the shut down just after the repair might be due to some process running in background for repair). BUT I am again facing the false battery % prob. I have repeated your method 2-3 times in past 12 hours but not able to overcome it. Please suggest what to do.


Thanks in anticipation.

Re: Xperia S battery drops to 0 while on a call

Hey there, I'm having the same problem.
My Xperia Acro S suddenly drops its battery to 1% from 59%.
Then it shuts down automatically.
After that, I turned it on again, and after 20-30seconds, then phone would shut down again.
My phone also became super hot!
