Given that the Hudl2 battery is not the greatest, I've been using Battery Doctor for a while now but I keep having to kill apps draining the battery every time I turn on the device which is a pain. I've given DU Battery Saver a go a while ago but found it a bit ad-intensive. You can set Battery Saver to auto-kill apps, but I wasn't convinced it was helping.
Can anyone suggest a good app to maximise battery life?
Presumably rooting helps (I believe you can then step the processor down a bit which would help and alleviate how hot it gets as well?), but I'd rather hang on to see if we get Lollipop before I start thinking about that. I recently upgraded my Moto G to Lollipop and found the battery lasts significantly longer, so fingers crossed it comes along at some point.
I've turned off GPS, bluetooth, wifi etc. Any other ideas?
