Here's the screenshot of my SOT, it's reduced with lollipop, had almost 6 hours with kitkat, with autobrightness, I m using wanam Rom
It still has this wifi battery drain but no drain when u keep it on power saver mode which I dont use much.
Regarding the charger thing, I will explain in detail, cant promise tomorrow but day after tomorrow I will do it. You can whatsapp me if u cant wait.
