that is truly incredible... what do u do with the phone, leave the screen on some and that's it? lol what apps are being used, etc. calls made? that's only roughly an hour/day of real use, which, given this phone's battery capabilities on doze, I guess makes sense
I just turn on the screen when I need to use it, to text, look something up, lunch hour browsing, take some pictures, the odd phone call, etc. and then I turn it off. I'm not one of those people who sets the phone down and leaves the screen on for 1 min until it times out (I see so many people do that). I use it to stream to my Chromecast too but that doesn't use device battery really. I don't play games. I don't have Facebook, Instagram, or Facebook Messenger installed (I have decided I hate all things Facebook). I have about 40 apps installed, mostly google apps, news apps, WhatsApp for my group chats, Netflix, NHL, Chive, etc. Honestly I have no idea how people get to 3h of screen on time in a single day unless you are playing games, or have a LOT of time to kill staring at your phone (maybe a flight or long transit commute or something which is much more reasonable). I'm in 5 group chats, do some light lunch time browsing, and rely on my phone pretty heavily and it takes me 2-3 days to hit 3-4 hours of screen time.
Location set to "battery saving" (only reason you need high accuracy is when you use Navigation), and I turned off the "follow my device" location feature. I don't think I'm doing anything too out of the ordinary, but if I pushed it I could get a full 3 days of battery life. Google photos set to upload & sync only when charging.
The screen is the battery killer, and I don't have a ton of screen on time, so Doze is definitely to credit for the huge battery life (it lost 1% last night, from 30% to 29% over 8 hours of sleep). That 29% was what I was left with to start this third day since the last charge, and I decided to plug it in at 12% in the afternoon. I do keep my brightness pretty high at 75% though for better whites. I'm glad I'm not staring at my phone for 3 hours a day to be honest haha, and in return I get amazing battery life.
It's fun to see how long it will last, but really, the thing charges in an hour, which is equally as impressive so even if I was charging it every day, it would be a complete non-issue.
