If there’s one app that can really make a difference then its BatteryTime. All to often if your using a smartphone you can almost watch the power needle whizzing down to flat and your second coffee of the day is not even cold! Red by lunchtime, no it’s not possible. Whilst your mobile looked good in the shop, the reality of dual processors and a screen the size of a Mac truck are not quite what the sales assistant said they were? You've got all the power of snail at a red light. Well this should do the trick, BatteryTime has all the features you need in an application to maximize your battery’s productivity.
Saving your battery life isn’t rocket science, things like the back lite or having your wifi constantly switched on are the usual suspects, so lower the lite down or disable your Wifi. Bluetooth or Apps that sync up constantly can be found with a smoking gun. BatteryTime Lite is free or you can get the pro version for a $, install either and they'll soon point out which functions are draining your Lithiums.
