Re: Doze didn't work... ?
Click Settings > Battery > then the battery graph, and you'll see 6 bars beneath the graph starting with "Cellular Network Signal". That should be solid (unless you go into airplane mode or otherwise turn data off). It should be green (dark green is best, lighter green is okay). If it's Yellow, then that's a sign you don't have a strong signal and the battery is draining faster.
The fourth section down is "Awake". That should have a lot of gaps, especially when its dozing. If it's solid, that means the phone isn't going into doze.
Now I did plug in the phone since this morning so it erased the battery data from the night before. For today, the cell signal is dark green then red for a bit (I know I was in a dead zone) then light green then dark green. So, for today, it's normal I guess.
Awake has lots of gaps like you said - few solid green parts but very short.
If something is keeping the phone awake, the only real way to figure out what's causing the problem is by seeing if things updated currently and uninstalling apps until it finally does doze. However, some apps are notorious for keeping phones awake - especially anything by Facebook. I had an issue with an app a while back (for me, it was the Fi Spy app). It didn't show up in the list of apps (first battery screen) and I only found it by uninstalling apps.
I sure hope I don't have to start the app uninstall investigation process. I do have Facebook installed but it will be the first to go if this happens again.
I'm going to charge my phone to 100% tonight and leave it unplugged overnight. If it happens again, I'll look at my battery report closely to see if I can identify what's happening. And, BTW, I do have a strong WiFi signal in my bedroom.
I'll report back on this thread.
THANK YOU!!!!
