Battery AC DELCO or SAMSUNG

I get the exact same as you with my s9fe and s9, 16h and 11h, equal screen off, 100% usage.

The s9fe's get great screen on battery time much better than s9's in my usage.

I put in ACDelco and surprisingly it lasted till last week (Aug 2024).

The AcDelco I installed in 2021 December died this morning so I'd say it's good. It lasted almost 3 years and I only park outside + have a whole sound system + aftermarket horns.

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

I'd recommend AC Delco - had 2 batteries from Repco (made by century) for my VZ Commodore Wagon and returned them both for dropped cells within a month of fitting - had no issues with the AC Delco at all, even leaving the car sitting for over two weeks it still started first turn of the key

I noticed too, i mean, it's worse but it's not that bad, with the tab s6 I could do from 9 to 10 hours sot, sometimes even 12.

With the tab s7+ I can do 8-9 hours sot, so not that bad

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.

Replaced battery in my 2012 Chrysler 200 - after being in car 12 years - yes original battery - bought car off show room floor. Replaced with AC Delco 580 CCA - as per manufactures specs - exactly 2 months to the date - battery absolutely DEAD !!!!!!
