This is insane now. When I first did the damn update the phone was better then before. The battery life lasted a long time and I had over 6 hours of OST for the first 2 days. After that everything went down hill... I noticed my battery dropping a whopping 30% twice now for no reason at all. I thought it might have something to do with two apps that I had downloaded. So I uninstalled them... Nothing happened. I also noticed my phone took several hours to charge on my Samsung charge pad. When usually it takes a hour and a half. So in the end I had to reset the phone.. This better work because I don't know what else to do now. If I'd known this would happen I was better off with not updating at all...
