Do you want to save some power and make your device work longer? If yes, then Battery Doctor may be able to help.
Battery Doctor is a small application that says it will optimise the power consumption of your device, prolong the battery life and then reduce the need for recharging. In fact it (at least) attempts to do so – it scans your device, finds the apps and processes that consume power and then allows you to turn them off or keep them running. In addition it shows estimation as to how much more time you have gained. All this is done in a nice interface that quite honestly catches the eye.
We can’t really say if Battery Doctor works but you can try it and see if it does so. You can find this free program here on Google Play.
