What's your battery health and cycle count?

[Gray Area]

Well the charge count (1) is correct but idk how it calculated my battery health at (75%) lol . This is what the stats say on my brand new s20 ultra

I think it needs few more charge cycles to get more accurate

Try the AccuBattery app. You need a charge cycle of at 21% or more for it to estimate battery health.
By avoiding full charge cycles it gives a fairly good idea of actual battery health and reduces wear just to gauge it.
Sort of couterproducetive to use full charge cycles.
It takes a couple 40% charge cycles but it's estimate was within .025 MAHs of the actual amount shown at a full 100% charge I did.

Pretty good. Still playing with it. It helps you to develop an almost none destructive base line charging strategy.
Very little damage is done going from 40-72% if you keep it cool. That's enough charge for me to go 4-6 hours before another 20 minute fast charge.
Pretty cool.

Normal LI lifespan is 300-500 full charge cycles... much more full charge cycles if you do partial charges to below 80% but charge before you reach the 30% threshold.
Going below 20% puts a lot more stress on the pack.
LIs love partial charges like this...

Yeah , that's a good battery health app

I'm having a similar problem with my s8.
The battery will stay at 100% for one or two hours then drop by 20% or so. It will then drop till it gets to 30% (or so) and then dies.
The other thing is, on occasion, I will charge the phone, take it off the charger and then right away or within a few minutes drops to 0 and auto shuts down.
I am thinking it needs a new battery too.

My s8 that I got over 3 years ago on pre order

905 discharge cycles

72%

Dell Inspiron 15 7590 2in1 (i7-8565U, 16GB RAM, Nvidia MX250 GPU, 500GB SSD with 32GB Optane cache, 4K touch screen that can fold all the way back like a tablet, active stylus). Great machine for my needs, both leisure and school, updates Windows far faster that most cheaper machines, etc... I upgraded from a kludgy custom Celeron based PC that required Windows 7 to be remotely usable.

I have the same exact laptop!! It seems nice so far but I haven't used it much yet. I got it to see if I would wean off my beloved W7 PC! So far I have not! It was a laptop upgrade from an high-end HP Pavilion with Vista sitting in a closet for 10 years!!! Never liked it. rarely used it.

My S8 battery is showing small signs of wear so I am thrilled to find this thread. I had no idea I was not supposed to let it get down below 30-40%. I also have burn-in from Google Maps. I can see pink-red navigation icons faintly on a white screen. I was told (lectured) by verizon reps at Best Buy that I should downgrade the screen brightness, turn off display while using maps (huh?), and use dark mode as much as possible - less wear and tear on pixels... no color better than any color.

Can't wait to check out those battery health apps. Will report back.

Hi Guys,

a bit late to the party. Still i am curious, how has your battery changed since you posted here?

Mine is also from Late 2018 Galaxy S8+

82% 944 Cycles

I rarly switch it off, always fast charged it, started charging most times at 15 %

Gonna upgrade to a S20 soon tho, gonna miss the S8+
