I have been using my HTC Sensation for a year and a half already and recently it's starting to crank up.
It started last week when I was using my phone when suddenly it just switched off by itself and no matter how I attempted to switch it back on again it would boot up to the lock screen page and baam, it shuts off again. It doesn't restarts by itself or anything, it just simply switches off and no, I am unable to switch it on again. The only time I am able to do so again is when I plug it into a power source, that is when it would finally be able to start up.
At first I thought that it wasn't something big until recently it started occuring more frequently and I noticed that it only occurs whenever I have my 3G switched on. If I'm plugged in, my phone would still be working without switching off even though I have my 3G switched on. But when I unplug it from its power source, I'll be able to use it with 3G on for a good 20-30mins or even lesser at times and there it goes shutting off by itself again. What actually got me dumbfounded is how I can be having 80% of battery power when this happens.
I have tried the using a card/paper as a wedge for the battery so that it connects better but to no avail even though I have noticed that indeed, my battery seems to have some extra allowance for it to fidget about within the confinements of the spot which is allocated for the battery. I have tried the switching the phone's data usage to GSM only as well as switching it to WCDMA only but both still didn't work. I have also done a factory wipe which didn't work, super wiped it before flashing ARHD once again which didn't work as well.
To make things worse, my phone is not covered under warranty anymore and my only last hope is that the problem lies with my phone's battery rather than the PCB board which is why I'm putting all my hope on the Anker battery which stocks would only come in next Monday which I don't wanna spend on only to find out that it's not gonna be able to save my phone from its miserable plight...
This is my phone's setup:
Android Version 4.0.3
Sense Version 3.6
Software Number - Android Revolution HD 6.8.0 XE by mik1986
Kernel Version - 3.0.16-g31a4fc7 htc-kernel@u18000-build-144 #1 SMP PREEMPT
Baseband Version - 11.76A.3504.00P_11.24A.3504.31_M
I'm really desperate to find a solution to this so if there's anyone of you who has faced this issue/solved this issue please enlighten me as to what I can do, any/all help would be greatly appreciated.
