Some issues that have been brought by alot of users across the world using android firmwares
- Battery tends to drain abnormally upon requesting HSDPA and 3G
- Improves GUI animation and performance.
- Facebook drains alot.
- Web browsing drains about 2% or so when using it.
Solutions:-
1. Utilize the entire battery usage till the mobilephone goes complete flat. This is what we called as battery recalibration.
2. Let it recharge.
*Solves my issues that the battery has a bad calibration (Due to my mobile phone was bought off the shelfs, sealed set, I may have suspected that the set was stored months away before it's officially mine).
3. Install Juice Defender (It usually turns off the HSDPA/3G network when not needed. E.g. when phone is on standby/sleep mode). Let the Juice Defender anaylze the phone, may take an hour or more.
4. Turn off "Background data" to prevent further requesting.
*Optional:- You may purchase a 1500mah battery from ebay. Have noticed that some country using the 1500mah versions instead of 1350mah (which is mine).
