[freebax]

Hello Friend
I met a real problem: (
I had no problem when I bought my smart phone and smart phone I've successfully updated
Unlike the Android 4.1.2 smartphone to Android 2.3 back chair back, but now I feel like my phone battery is too weak or too fast is empty: (
What strategy would you recommend for me?
And the only other way is to calibrate the battery?

Restart your phone (power & volume up at the same time for 5 seconds ) and if that doesn't work, re-install the update all over
