    Just curious as to how everyone is doing with their battery. To check the health and cycle count, download "Phone Info Samsung" by vndnguyen from the Play Store, open the "personal" tab and tap several times on the "usage history" text until it shows the battery health (cycles are shown by default, and if you don't wanna have to do all the tapping every time you want to check, simply get version 3.8.0 from APKmirror).

    Here are my stats for the S8 I bought new in mid August last year, and it is pretty good given the fact that I don't religiously adhere to various draconian suggestions you might see on the forums like at-all-costs keeping between 40-80% and similar stuff. I just avoid discharging below 25-30% and I fully or near fully charge every time (sometimes I also do short "boost" charges, i.e. using a fast car charger to get a few extra percent while too/from the supermarket).

    Straight Talk was selling 'em last year and I didn't wanna drain my savings especially since I had decided to also purchase a fairly pricey laptop shortly after. So far so good aside from some somewhat annoying screen burn-in caused by my Whatsapp addiction. Still a great phone for just $300 (where else can you get a still very powerful 800 series Snapdragon for that little?).

    True, I had pinkish tint s8+ that was common.

    Lol, it says 40.6% , 200 discharge cycles.
    Battery is at 48%
    It may have run awhile. The battery is between 96-100% of it's rated capacity.

    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.

    Exactly my situation plus the imprints from the keyboard (including hexagons from my previous SwiftKey background) and Whatsapp UI. The navbar isn't pink at all as it is basically set up as a black/green battery indicator.

    Took this picture a few days ago carefully with my spare Galaxy A6+. The screen is quite burnt in and is supposed to be plain gray. There is no Samsung store anywhere near where I live in New Mexico, so I'm kinda stuck with this. The phone is still perfectly usable. The first burn-in that happened was actually the G logo from dark mode Gboard, so I switched to SwiftKey and ditched all dark mode but that also burnt in badly as you can see. I casually mentioned this burn in to someone at a phone repair/accessory/refurbisment shop back home, and the repairwoman in the back of shop overheard me and in a very judgemental voice said "that is because you keep your screen brightness fully turned up". Sorry, but I shouldn't have to decrease my brightness on a premium phone just to prevent degradation. This is clearly the fault of Samsung. Meanwhile my old OLED tablet never experienced any burn-in and was heavily used with HUD based vide games and various PC emulators. But yeah, the S8 is EPICLY notorious for burn-in but that wasn't much of a worry at such a low price point. This is actually why I refuse to pay $1k for a brand new model as I know the screen will degrade no matter whether I OCD-level protect it or not. The phone is there to serve me, and not the other way around lol.

    Oh yeah , best keep a darker background to see it less , I always had mine on auto brightness and adjust accordingly if needed but trained it where it works in most situations automatically now, i can't get that on my pixel just doesn't want adapt to my liking.

    I hate adaptive brightness. I like my screens at full brightness as it looks alot nicer (part of the reason I like AMOLED is the brightness/glow it gives off) and doesn't give me the weird feel that low brightness levels (and rapidly adapting levels) give me as AMOLED uses low frequency PWM (unlike the high frequency PWM on LCDs that doesn't bother me).

    I will be in literal HEAVEN when Samsung switches to MicroLED for phones as that, from what I hear, has basically the same benefits as OLED minus the downsides.

    Ouch! 78.70% battery health though I've had the phone from brand new since October 2018.

    Have you been super frequently bringing the battery to very low percentages (below 10%) or fully emptying? It is OK to do it on ocassion or when you cannot get to charge your phone, but doing it habitually will nuke your battery quickly. How many cycles do you have?

    More recently I've been getting to low, I kind of knew that but thought I'd be getting a new phone. However, the current price of flagship phones and those horrible cut outs on front I've decided to keep my s8 longer. I'll just need to manage looking after the battery better now.

    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...

    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.
