Battery Bosch or SAMSUNG

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.

Bosch batteries in my older bmw lasted around 5 years but I was told it’s recommended to change every 2 years.

On my A9+ I turned my display down to 60hz had it since February battery life is excellent.

Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.

looking at that reciept seeing Enhanced flooded its even worse, we are a main dealer of Bosch batteries and their EFB rated voltage is 12.6V when not in use not sure for the other big battery brands

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.

Yes, I have had this tablet for less than a year with moderate to medium use and I am already looking for a replacement. I am looking to do it myself and I am not that skilled but I will give it a go, but it isn't great that the battery is already needing a charge once a day even with "battery saver mode" applied.

I had 3 such tablets in a row. 3 times the worst battery. I'm very disappointed.

I've had a couple of issues with my BMW 5-series, I found Bosch batteries don't last as long as they should. I changed them twice in the span of 3 years or so, each time resetting the battery management system with the correct capacity. I changed it to a Deka Intimidator and I'm much happier with it.
