PowerSaver is a new jailbreak tweak, which lends your iPhone the ability to execute specific actions based on the amount of battery power you have remaining.

For instance, when you reach 50% power, you can have the iPhone dim the brightness, skip to the next music track, or lock the screen.

Have a look inside, for a full video synopsis of PowerSaver…

In all, you can program up to 14 different actions using PowerSaver, so you can really get specific when it comes to executing actions at certain battery intervals.

I did notice that not all of the functions executed at the exact battery level that I indicated, and that some commands, like Safe Mode, were best left alone, due to the fact that it caused an infinite respring loop.

Fortunately, most of those issue have been ironed out with the 1.01 update, but I have to be honest and say that the tweak can still be quite finicky at times.

If you want to try out PowerSaver for yourself, head over to the BigBoss repo on Cydia, where you can purchase it for $1.50.

Do you think something like this would be helpful to your day-to-day iPhone routine, or more of an inconvenience? Let me know what you think in the comments below.

    Not my cup if tea. Just go easy one the games and turn your screens brightnes down and that should save you some battery power. Works for me…

    Hey Jeff, this question doesn’t have to do with this topic. I upgraded to ios 5 GM and since the official upgrade is tomorrow, is it a different version? If so, how can I upgrade? I am not jail broken yet.

    Just check for over the air upgrade in the Settings App > Genarel

      Word of mouth is, you can’t update OTA with jailbroken iOS 5. Can anyone confirm this?

    How about an app that changes brightness according to what you are doing? Example when I’m just at the homescreen the bar could be like 50%, when I fire up a game like infinity blade it goes to 60% and when I go watch a movie the brightness goes all the way to 80%.. But the percentages should be configurable on each specific action. It is bothersome to change the brightness bar even with SBsetting evrytime I do something else, if there is a cydia app like that, I am definitely sold..
