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 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.
my dishwasher has around 200 mile motorway range on a 64kWh net battery, which'll get me from Oxford to Darlington on a single charge, I could get to Newcastle if I camp behind a truck for most of it. My car is also stupidly inefficient for an EV, better EVs like a ID.3 or Megane could go further with smaller batteries.
My 3 years old XC60 battery has been diagnosed as bad 55% last 2 weeks ago, I said to them keep it as I feel they are still good and road worthy. Gonna do a snapshot again at another 6 months to evaluate.
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.
The battery is almost certainly dead.
Something else wrong with your car likely killed the battery and if that's the case buying a new battery will just result in the same problem pretty soon.
That battery is absolutely cooked, sounds like the cells have sulfated to hell or there's internal damage from deep cycling
The fact that it's only taking 72-94Wh when it should be 600Wh is screaming dead cells, and that voltage drop from 12.8 to 4v in 2 hours is not normal even with parasitic draw
The battery is trash - if it was at 4v, the cells are either internally buckled/shorted - or the AGM is damaged and thus will not hold any charge (no capacity).
Looks like I'm getting a battery replacement. Very disappointed in Samsung this year.
