New but not recent
I got this to try and revitalize my Galaxy S8, that I got in 2017 and is still working but whose battery life has degraded to the point that it only lasts about a day on light to moderate use.
This product is a legit S8 battery, and it will work. BUT I was hoping for an S8-compatible battery manufactured in maybe 2021 that would perform comparably to a new OEM battery. What you'll get is an actual OEM battery made around 2017. That means it's an old battery that's degraded to the point that it's not much better performance-wise in 2022 than the one you're trying to replace.
It does indeed look new as in "not used before", but not new as in "recently manufactured". If you are trying to extend the life of your S8, don't get this, take a gamble instead on some of the other batteries listed that are compatible, more recently made, and possibly have even better capacity than the OEM. I should have read more of the reviews, as several of you out there did try to warn others about this situation.
If you are, however, trying to fix a broken phone and need a battery that will work for an S8 whose battery is not currently working, then this is OK and will work. Just be aware the performance is not going to match a truly newly made battery.
As the seller at least charged a low price, I'm not going to bother with a return, but I agree with the reviewer that said swapping out the battery is too much work if you're going to just get comparable performance.
