So I have updated to this version and I am facing massive battery drain. I have looked everywhere to find a solution for this and most of people say to do Factory Reset. I have done hard reset and standard one from "Backup and reset" but nothing has really changed. (I have cleared the cache too.) I have turned off almost everything. -Changed "Keep Wi-Fi on during sleep" to "Never (increases data usage)" -Changed "Network mode" to "GSM only" -Turned off "Sync" and "GPS" and also location requests on every application that has it in its settings (I do not even use Sync...) -Turned off "Touch Sounds and Vibration" And to be more ironic I have "Power Saving" on. I would also like to add that this is the second day of running this update and first day of having battery fully charged while on this update. Battery keeps draining without even touching the phone, although I have had WiFi on for couple of times just for Whatsapp... I have also read that it will require a couple of more charging for the battery to adjust, but can not blame me, I am kinda desperate and hoping to get some answers. I have also noticed that the WiFi response is kinda slower, on previous version WiFi was functioning normally but I am noticing that my internet is slower even though I am in the same room where my router is and read somewhere that this update has some errors with WiFi, could that be true? I really do not know what more to add, I really am desperate. LOL Thanks in advance. P.S. As I was writing this, probably took me 5 to 10 minutes, my battery dropped for 2% without touching the phone.
