Battery SAMSUNG or OEM Mercedes

I did the same replacements two weeks ago, it took about a week for the battery to recalibrate, definitely am seeing the improvements now.

Historically, OEM Mercedes batteries are really good and last many years.

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.

Everyone's suggesting things that might save you half a percent or so, but no one has pointed out that by driving at 80mph, you lose *around 30% more battery* than if you were doing 70mph over the same distance

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.

I don’t have an AMG, but a 2024 CLA 200d and having battery drain problem is annoying to say the least and haven’t even had the car for a month when it all started happening. It’s been at the dealer for the past 3 days and no voltage drop there. They gave me the signal blocking key case and they upgraded the software and still can’t find the problem. Third visit in the month and new battery installed too.

same issue with daily driver 2021 E63. In this case though, the car doesnt give me a warning as much as the Mercedes app on my phone - it alerts to low battery -even critically low, but when I get into the car it starts and there is no message.

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.
