My Android G1 phone will not last w/o charger even when left overnight. There must be something that I am doing wrong... Maybe it is just too old now.
If you’re a recent convert to smartphones, you’re probably still discovering all the amazing things that your new BlackBerry, Android phone or iPhone can do. But one thing you most likely found out right away: the more you do, the shorter your phone’s battery lasts.
The tips in a nutshell:
* GSM is better than CDMA
* Dim the screen
* Turn off Wi-Fi and Bluetooth
* Get a newer smartphone
* Check mail manually
* Use "airplane mode"
* Disable animations
* Get an App to Aid You
* Replace the old battery
