Xperia Ion switches off Immediately after it reaches 30% battery

[pratikrd]

Hi folks,

I recently updated the phone to ICS. After that I have been experiencing a weird behavior in my phone. The phone switches off immediately after it reaches 30% of battery life. And also the Power saver mode is not working.

Any help is appreciated.

Is there no other way of fixing this issue? and is there anybody else who faced the same issue?

it could be an app acting up, could be a taskiller, antivirus or battery app, but the best way to solve software issues is by repairing your phone

I uninstalled the Advance Task Killer and it looks like that was the issue. So there wasn't any need to repair the phone.

I've repaired this problem maybe! just do following instruction:

For those of you who had the Sony X10, you knew that there was a battery calibration method. I won't go into detail about how it worked, but this is very similar so X10 users should be familiar.

Here's how it works:

Step 1: Charge battery to 100%
Step 2: While phone is still plugged into charger, hard reset phone (volume up + power)
Step 3: When phone turns off, unplug charger
Step 4: Turn on phone (Note: If calibration is needed, battery percentage will be less than 100%!)
Step 5: Plug in charger and charge to 100%
Step 6: Repeat until battery percentage is 100 upon restart.

WARNING: THIS IS UNTESTED. I AM NOT RESPONSIBLE FOR ANY DAMAGE THAT OCCURS TO YOUR DEVICE.

Your battery percentage should increase incrementally with each restart. Example: if on first restart, your battery reads 94%, then it should read 95 or 96% on the next restart.

Please test and report back. After doing this twice my battery life seems much better (currently down to 57% on 8.5hrs of moderate use). Today is the first day, so I'm not sure if it's just an anomaly. Any feedback is appreciated!
