AOD vs Night Clock - Battery showdown

[spasell]

So with all of this "my phone might explode if I charge it overnight " I decided to try an experiment since I am not leaving it on a wall charger now (wireless charging is 100% fine btw. No heat at all).

First night in hotel I unplugged at 100% and used the AOD. In 6.5 hours the phone was at 88% the next AM. I was surprised by that.

Now I didn't gimp the phone but changing any settings. So it's BT on to my Gear 2, wifi on, etc.

Next night, same settings, same time. 100% and 6.5 hours later using just the night clock feature I was at 94%.

12% drop with AOD
6% drop with night clock.

Now it might not be that surprising. But to me I thought it was interesting since Samsung indicated it uses 1% or less per hour for the AOD.

Tonight I am going to test it with neither one on and see what happens.

Could you add powersave medium and MAX to your study too? That way we can get a full picture of power consumption in various stages.

To get a somewhat actual controlled test, you would need to gimp the phone so that the battery drain would be isolated to the applications you are testing. There are way to many processes running in the background at any given time to say that the AOD caused that much drain.

Just saw this but I wanted to chime in with what ive seen with my own note 7.
The always on display seems to brighten its self at times. then dim out again. back and forth constantly. doesn't seem like it should do that but I think its because of the tv getting brighter on certain scenes. I notice it out of the corner of my eye while watching tv when laying in bed at night.

My AOD dims and brightens of it's own accord as well. I heard there are two light sensors on the Note7, front and back. I assumed that was the cause of it. I wonder if turning auto brightness off has an effect on AOD.
