You can get an Deka AUX18L from batterymart.com for $159 shipped to your door. Deka is the OE manufacturer of the BMW battery for the i3. My original battery lasted 7 years, it’s a no-brainer.

Pros: lasted 7 years
Vehicle: BMW
Part number: AUX18L

SAMSUNG Battery

I got the Note 9 the same day as my buddy did. I was very careful about slow charging from 50% to 60% (overkill, I know) and he was not careful. His phone crapped out after 2 years but I used mine for 4 years until I decided it was getting slow.

Pros: slow charging helped
Cons: overkill, I know

I only use deka on my service rig. Usa made quality. Though listed at 540 CCA, MY Midtronics tester shows they output 650 - 750 CCA.. I easily get 7 years use in the field with these.

Pros: USA made quality, high CCA output, long lifespan

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.

Pros: battery drains quickly
Cons: drains horribly

SAMSUNG Battery

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.

Pros: super fast, useful
Cons: battery worse than expected
