Don't know how/why but been getting amazing battery life recently

[dragon192]

When I first had my phone 2 months ago I was getting 3 HOURS SOT max. Currently I'm sitting here and I'm at 5 hours SOT with 20% to go. Used Spotify and Bluetooth streaming for about 2 hours today plus a lot of browsing. Auto brightness and power saving mode enabled.

I think using WiFi makes a big difference. Downloaded 430MB today. I think if it was cellular data it would be a lot worse.

Is this typical? What's going on?

I get anywhere between 7 and 9 hours sot, but I ensure that almost the entire interface in the phone is black.

At the moment I've got nearly 4 hours sot with 68% to go
