Battery OPTIMA or SAMSUNG
I bought a red top optimum for my 2019 forester sport. Have had it in for almost 2 years without issue thus far.
My replacement was a Blue Top 34M and it's 8 years old. No issues with Optima here.
I get the exact same as you with my s9fe and s9, 16h and 11h, equal screen off, 100% usage.
I've had great luck with the Optima Yellow Top DS46B24R for Gen2.
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.
The battery is an Optima Yellowtop 5.5 75h, I changed it in 2018. It has central poles and the negative pole near the windshield. Now given the very high prices of the Optimas and since their lifespan disappointed me, I wanted to get a cheaper battery.
Galaxy tab s9 has a very bad battery, confirming here
my Optima Red Top failed after 2 years & 7 months. this is the last time I'll buy one.
Optimas are not the brand they once were, I would never put one in my vette after the brand new $300 red top I put in my Durango basically exploded a week after I put it in.
