Kerbear: Would buy again

BT: Actually received a 5000mAh battery. As stated in other reviews, THE challenge is getting the back off of the S8.
I used a hair dryer and was patient. Pay attention to the small cable connectors--you need to here a "snap" to know that you've got them connected correctly. So far it's not like having a new phone, but it is like have a new S8.

Marc B. Stanis: The hardest part, by far, is removing without damaging the phone's read cover. The cover is pretty flimsy and made of plastic and glass. The glass coating gives the phone it's aesthetic appeal but also makes the cover extremely fragile. It will easily crack if too much force is applied. You will need to be patient, slowly and carefully removing the back; which can be a cumbersome process. The directions and tools provided are more than sufficient to succeed in replacing the battery and not damaging the phone or it's rear cover.

Things to keep in mind.

1. Don't count on your phone being completely waterproof after this procedure unless you reapplied more sealant. Doing so may cause issues should you need to replace the battery in the future.

2. It is easy to damage the rear cover during the removal process. If you do, new covers are readily available.

3. You should probably watch a video on how to remove the rear cover to understand what you are getting into. If this is not something you are confident you can do, or want to do, you might consider buying a new cover. It is much easier to remove if you are not trying to avoid damaging it.

4. $15 for...

NathanNathan: I want to preface this by saying the install is just as easy or difficult as any other repair to this phone. I used high quality tools I previously bought. The tools that come with this product are cheap and simply not enough to do the repair.

As for the battery, the one they sent me was dated 2019 (2 years old at the time of review) meaning the battery was already old and degrading. What's worse, is that the measured capacity using AccuBattery is actually WORSE than the original samsung battery I had in my phone! (See the screenshot attached) (the original battery had degraded to 2400mAh)

Not only was this a waste of time and money, it also wasted a lot of expensive single-use adhesive which doesn't come with this product. The adhesive that does come with it is only for the battery itself and is significantly oversized making for a sloppy installation.

AHC: My V10 doesn't want to die, except for the batteries. This is my 5th battery for this phone because I didn't register the 18 month warranties I got on the last two 3000MAh batteries, and they started to lose charge. Packaging for this battery was one tiny battery-sized box loosely placed inside of a much bigger box, but thankfully was handled by the gentler Postal Service.

Battery was the right size and had no charge upon arrival, but once I charged it, I haven't seen anything wrong with the battery. Weighing this battery showed that it is onlt 2 grams heavier than the 3000MAh battery (3000MAh 49.32g vs "4300MAh" 51.34g). I used CPU-Z to check the MAh on there and it said 3000, maybe cause the phone will only say that, but really makes me question what this really is. I do; however, notice that this seems to discharge a bit slower (even in the more intensive apps) compared to my previous batteries when they were new.

I also noticed that this battery is Li-Po, but the last 4 were Li-ion. With that said, I just hope when summer comes around and my phone gets hot in my pocket, that the battery doesn't swell. Only time will tell. Will update in a few months if the phone...
