michal_vitalos, Jan 17, 2018 : Hello, Doze Mode is not working as efficiently as it should. Battery is still draining even throughout the night. At the time I was using the Nexus 5 and the Lollipop update came out, Doze Mode was a nice invention and when the Marshmallow update came out, it was great, there was maybe 3% drained during the night. On Nougat, Doze Mode should work even while walking with phone in a pocket but it isn't working when laying long hours on the shelf. Does anyone has this same problem?
