I didn't do any connecting or disconecting. I don't know whay this was happening.
Anyways, I just can't get more than 5 hours SOT on my phone. Bluetooth and location are off. Wifi and Data are on. Brightness is on auto, but I'v noticed that auto allways sets it to 20% of brightness. I do no gaming on my phone, only about 30 minutes of phone calls, WhatsApp and Facebook with Syncing on. Is this normal? My battery life on 4.2.2 was definitly better.
