Battery Management Apps?

Can anyone recommend a battery management app that is not full of adds and actually works by extending battery life?

I have tried a number but they are ether full of adverts or if anything reduce battery life.

Any recommendations welcome…

Thank you.

Have been running without a battery management App and the phone seems to last longer then with any of the 5 Apps I tried so far.

All the battery saving apps I’ve tried, have not worked, or as you say, use more battery.
I’ve been using wakelockdetector, which tells you which apps are using most power in the background or when the phone is switched off or if you have any wakelocks . I’ve been using for over a year with no problems.


Looks interesting will give it a try… thanks.
