Hi, After the latest Android upgrade on my Samsung Galaxy Note 4, I've noticed that the battery consumption has become really high. I haven't done anything different after the upgrade. The screen brightness of the phone is always set to medium, I switch off WiFi, 3G, GPS, Bluetooth interfaces when not required, also all the apps are now optimised. I've even uninstalled most of the apps that I don't use and still my battery level drops really fast. Example when I started typing this message the battery level was 42% and now it's 40% in just a matter of 3 mins. Anyone able to help?
