I use Low Power Mode so often that I sometimes feel like something’s wrong when I don’t see the little yellow battery icon in my Status Bar. The point is, I like saving battery whenever I can – even when my handset isn’t low on juice. On the other hand, using Low Power Mode isn’t without its downsides.
For example, you can’t change the amount of time it takes before your handset falls asleep automatically from inactivity. But that’s where a newly released and free jailbreak tweak called LPMAutoLockTime by iOS developer smokin1337 comes into play.
