If you have been plagued by the faulty Samsung Captivate turning off even when you have a fully charged battery, fret no more. "Captivate Keep Alive" will allow you to use it as a phone rather than a paper weight. The app will prevent the CPU taking naps while the battery is above a threshold you set stopping the phones random shutdowns
* Try to keep the threshold as high as possible without shutdows, that will help your battery.
* Get a replacement phone from AT&T if you can.
