Battery SAMSUNG or OEM BMW

BMWs are super good on batteries. They seem to last 9 years or more even in the midwest with extreme cold.

I got a full ten years on mine. 2012 F30 320d that i've had from new, now got 85k miles.

Bmw e91 318d del 2009, cambiata la batteria originale quest' anno.

low miles 10 yr old vehicle means its possible it has the original BMW factory installed battery. Some of those can last 10 years, I had a 2013 bmw 3 series and in 2022, I finally changed the original battery.

The OEM battery is AGM. If it was an OEM battery it wouldn't be lead acid, at least here in the US. Not sure what you're talking about. I installed mine three years ago and have had no issues despite winters that range from below 0 to summers that reach 100. Fahrenheit obviously.

OEM batteries are made from fairy dust. I still have my original one in my E92, made in 2007. Def recommend getting an OEM 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.

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.

Galaxy tab s9 has a very bad battery, confirming here

I just bought a Tab A8 to replace my 6 year old Tab A6 and I am sad that the battery life is worse than the A6.

I used the tablet at night in bed for about 90 minutes to read news and I get 5 or 6 days use before needing a charge. The A8 lasts 2 days.
