OK, I'll keep an eye on it and take the correct screenshots next time. I know it's best to charge the battery more frequently and keep it between 40 and 90 or so. But this is real life: I can't be managing my battery all day

And I was curious to see how long it would hold.
I rarely use the screen at full brightness, so that's not the cause. Bad reception: could be. But I spend most of my days inside close to the Wifi, so it's not from data. Also live in the city so pretty good reception overall for mobile connections.
And also: I didn't have this problem on other phones since like....the S6 or so

Not on recent iPhones, not on the S7, not on the S7 Edge...But now I feel like I'm living in 2013 again :/ (As in: battery anxiety every day
