Battery SAMSUNG or OEM Mercedes

For my Mercedes sprinter I had the same battery in it for 10 years. I went and bought it at the dealership. Since the last one lasted 10 years. I shouldn’t have a problem with it.

Maybe they’ve finally fixed the Doze mode they promised? Because, from what I can tell, my battery never improved after they released One UI 7. I’ve had this phone for two years, and the battery always dropped quickly - even when it was just sitting idle. But today, for the first time since I got the device, I unplugged it in the morning and still had 50% remaining by midnight.

I get the exact same as you with my s9fe and s9, 16h and 11h, equal screen off, 100% usage.

The s9fe's get great screen on battery time much better than s9's in my usage.

I could get about 10 hours of youtube at around 20% brightness with average volume at 60hz locked Not as good as previous tablets imo.

Happened to me too, the first day of usage. Weirdly, when i restarted, it dropped from 100 to 92. Then another time from 80 something to 60 something. It was probably some battery reading issue, cuz the overall runtime of 10hrs of screentime was not affected.

I recently got one, somehow it feels less. Idk if it’s because of the software but it seems to be draining even while being idle. Which is weird. People are quoting 7-9 hrs of sot and i feel like am not getting anywhere near that.

Just bought a new G63, same issue!

I've had the Tab S9 since launch and the battery has always been naff. It's a great tablet let down by lousy battery life.

Galaxy tab s9 has a very bad battery, confirming here
