UPDATE: i just got my wifes car back from the dealership and it turns out it was the battery for hers. The voltage thats normal for her car is 14.8 volts not 13.4. He said there are 40+ computers and when the voltage is low it causes havoc in the car.
I personally use Samsung 50S and RS50. The RS50 or 50XG are the optimal choice in my opinion.
I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.
I drove a first gen Chevy Volt before I bought my 2022 MYP. I actually loved the Volt but it didn't have much range. The Chevy Volt had about 37 miles of range and my round trip to work and back was 34 miles. I drove that car on all electric 95% of the time.
I do exactly the same tasks and mine don't drain that horribly. For me the battery drains quickly while watching movies and gaming only.
I would say the battery use on my S9+ is between 12-15% per hour, depending on the use scenario. Quite close to you, it seems.
It is a bit worse than I expected (coming from a Galaxy Tab s5e, which had unreal battery for its age), but everything is super fast, so not bothered too much with it. And the battery is still better than on my laptop, so it is quite useful when talking about some note-taking, e-mails and browsing tasks outside of home.
I noticed that some activities and apps (e.g., note-taking on Samsung Notes) take more battery than I hoped, but it is what it is.
Edit: Forgot to add, settings are maxed out, 120hz, bluetooth on, S Pen used constantly and charged from tablet, etc.
Looks like I'm getting a battery replacement. Very disappointed in Samsung this year.
Never left me stranded besides a dead battery.
Chevy Bolt. Then it was recalled for the battery fire issue.
Chevy Bolt, almost caught fire they bought it off me
