Iv seen lots of diffrent tips and stuff so I decided with all the people worrying about battery life this might be a nice spot to get information. Use a 5v charger at 1 -2 Amps - The thunderbolts OEM charger is 5v at 1amp. Its inportian to use a charger thats 1 amp or even two. This can help the phone charge better and faster and will help the battery. Turn off Wifi, Bluetooth, and GPS when not using them. Even when not active they are still using power. GPS can be a big power drainer too. When at home use WiFi for data. Use auto brightness, the phone will adjust to the light in the room and this can help save power as the LCD Screen uses a large amount of your phones power. Bump Charging - This is when you charge your phone to 100%. After this you restart the phone and remove the power cord when it turns off. After it turns back on youll notice the battery life has dropped about 5-10%. You can charge the phone again now and get that power back. Its an issue with android reporting the power levels. If you do this lots eventually the battery will adjust and you probably wont need to do this anymore. Drain the battery before charging - If you can let the battery get as low as possible then charge your phone, this helps the battery break in. Wait - The battery is new and on many phones new battery's have to break in or condition. After a while you will start getting longer life. If I missed anything or you have some ideas just post below.
