I have had my Fairphone 2 since March. It is running much better on the new Android software - before it was glitchy and kept rebooting. However, over the past few days the batter life has deteriorated significantly. With average use (mainly Whatsapp and Chrome - connected to wifi), the battery lasts a mere 5-6 hours. I am not a heavy duty user at all, and I am using it the same amount as before and didn’t have this problem. Can anyone help?!
