Forgive me if there is already a thread about this.. But I have a Huawei Premia 4g, rooted, but with stock ROM. I just recently decided to use the app CPU Tuner. I got the basics down.. Simple and Powerful Config,Govener set on Save Battery, but other than that I left as is with Usage at anywhere between 260-470 mA/h. I still only lose around 15-20% every 2-4 hours.. But I feel as if I could utilize this app to be able to give my battery more longevity.. But I am no where near experienced with this app, modifying CPU, or undervolt. Based on experience.. who can help me find the best possible (safe) setup? I am willing to let go of some performance for battery life so that is not much of an issue.. (as long as it isn't super slow that is!) Any help I could get I would be very thankful. I think this would be a good thread to have around considering the greatest weakness of the Premia is the fact the battery is just so taxing.
