I hated the lollipop OS so I went back to KitKat 4.4.4. Now just in the past week it's been nearly impossible to get this tablet to full charge. It takes HOURS just to charge even 20%. Now I've noticed in this past week that google play services is taking up a whopping 36% of my battery. And it has never done this before. Not only that but on the battery graph it shows that my tablet has been awake and has never went to sleep. Even after sitting, doing nothing for an hour and half while I was in my physics class. Even for hours overnight it stayed awake not once did it sleep. So I'm starting to wonder. Does anyone know what's going on here?
