Battery SAMSUNG or Duralast

I usually get a Duralast Gold from pepboys. Not the cheapest model, but not the super premium one either. Most CCA.

On my A9+ I turned my display down to 60hz had it since February battery life is excellent.

I replaced mine in my 2018 GLE63s with an aftermarket one from Auto Zone (Duralast Platinum). I finally got my start/stop feature back which I had forgotten about and also forgotten how annoying it was to have it ????

I did just replace the battery in the Trans Am in the fall after 15 years (bought when I picked the car up - I really got my money's worth on that Duralast). It had never been on a tender and that car sees maybe 1500 miles in a big year. But of course it also has virtually zero parasitic drain. I didn't even realize how weak it was progressively getting until I had a no start moving it out of the garage for a wash. It started so much easier on the new batt, I was actually laughing.

I'm about to replace the battery on my 2013 acura tl 3.5L, looking for some advice on choosing between two batteries. The two batteries im looking at are the ACDelco Advantage 24FS or the Duralast ProPower Plus 24F-DL. They are similar in specs, same CCA though the duralast does have about 100 more cranking amps and 17 minutes more of reserve time. The acdelco comes with 18month warranty while the duralast has 2 years.

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.

I have the same tablet and I can confirm that the battery life is quite bad. I am flabergasted how any who has done a 'review' on it managed to get almost 10 hours of battery.

I did a few battery rundown test with lowest and maximum brightness and I could not get more than 3-4 hours at best watching YouTube videos.
