I downloaded os 4.5.0.77 Now that i have it i cant get one full day out of my battery. On old 4.3 i had no problem getting two or three days out of one charge...It goes down to two bars within two hours after being shut off and a full overnight charge..Any ideas?
First try pressing ALT and BACK button to bring up which applications you may have running in the background. That can cause some major memory leakage. If you see many open, shut them down properly by MENU > CLOSE.
Battery pulls often fix most issues, so try that after closing the apps.
DON'T power overnight!!! Once the battery is full, it needs to be unplugged and used until dead. People who charge their phones every night have little battery life. The battery becomes dependent upon that charge every night! So charge your battery to full, unplug and use until practically dead..over, and over. Use this technique and it will preserve your battery.
