Battery Energizer or SAMSUNG

Having ran both Duracell procell, and Energizer lithiums in RMR's, the energizers last 3+ years. I've gotten 2-2.5 years out of Duracell.

Funny enough I also have an 18 Elantra and had my battery replaced recently from Costco. What I got was a:

- H6-AGM

- 760/120/70 cold crank amps/reserve capacity/amp hours respectively

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.

Recently i was able to acquire some Japanese Energizer 2300 and 800mAh AA and AAA batteries...from my experience with the Energizers so far they are much much better then any other NiMH battery I've ever used including the Chinese Panasonic NiMH batteries.

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 actually like this change. It's telling me the actual battery charge. What I don't like is at least on my S 8 Ultra is it hits 85%, then starts discharging the battery. The battery gets as low as 81% before charging again. Personally I think this charge / discharge cycle is going to be more harmful long term than just charging to 100% and holding there. So I ended up turning it back off.

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.

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.

I started using Energizer a few years ago after EVERY SINGLE DURACELL BATTERY in a 24-pack I bought corroded just as badly as the 1st battery on the left in your picture! This was regardless of whether the battery was in a device like a clock that was always running, in a device that is used when needed like my flashlight, or stored in my home office.
