99% of all battery problems in Stinkapore is always signal. At home I forgot to switch on Wifi, 1 hour the battery drain was like 10%. Go office, 4G on also, 2-3% per hour lost?
Yah, i never tweak anything as well ... nothing much installed except the social media apps & messaging apps
Weak telco signal is definitely one of the battery drainers .... My battery drains faster when i'm in office (weak signal) compared to other places
let me introduce you to Llama. Location based control app.
1. Defined an area. It scans the cell towers at a defined area. For home I recommend set learn to 5 minutes and walk your entire apartment, house.
2. Event. When entering an area and exit an area what to do. For home, Enter - on wifi, exit - off wifi if not connected.
3. Profiles. Sound stuff, loud, normal or quiet.
So I when I am home, the wifi is on, sound is normal. When I leave home, wifi is off, sound is loud. When I am in the office, radio is set to 2G, sound quiet.
Have fun!
