My husband and I both have HTC Desires. We are "old school" users, basically using the phones for calls and texts, and some occassional web surfing. Our batteries don't get us through the day. We talk on the phones quite a bit as they are our business lines. Please help!!! We don't want to sync anything. I have auto sync turned off. We don't want to receive our email unless we log in to the program to get it. (yahoo mail). We have brightness turned down and WiFi turned off. I have also installed Power Control to only turn on Sync/Wifi/Brightness when I need it. I have installed Juice Defender, but don't know what would be best for the settings. Since we don't want to sync email, I wondered if a custom setting will help? I just checked my battery usage and found: Android system 33% Cell Standby 22% Voice Calls 15% Phone idle 15% display 12% Dialer 3% Any help will be greatly appreciated.
