Daniel P Anderson: I ended up not having to use this battery yet. I did ship fast and looks to be quality.

Rick Plavnicky: This kit is complete and contains everything you'll need to replace your S-8 battery. The instructions are accurate but a little short on detail so you'd be well-advised to look at a few YouTube videos before you begin. Look at more than one because different folks put emphasis on different areas of the work - you may encounter difficulty where one creator had it easy. As an example, I found removing the fragile back cover easy because a swollen battery had separated two thirds of it from the phone's frame. The included screwdrivers are of mediocre quality. Be very careful if you encounter a tight fastener - if you bugger up the head of a Philips screw it will be a difficult repair. When you get your kit, if you remove the included battery for inspection be sure to handle its ribbon cable with care to preserve its orientation. There's a tiny half-loop in the cable that serves to align the connector with its place in the phone. If the ribbon cable becomes bent it could cause difficulty with connector alignment. Take the time to carefully clean all old adhesive from both the phone and the backplate. The flat of the plastic spudger works well for this. The adhesive will solve with...

CottonwoodFarms: I just installed this yesterday so I can't comment on the batter longevity. The instructions about how to disassemble the phone were complete and legible. But then they just kind of ran out. Specifically, it would have been nice to have had some information on how one is supposed to reconnect the finger print sensor. I eventually just unglued the sensor from the back of the phone, left all of the original glue in place around the sensor, and slapped the back on. It worked but it's probably not the best solution. New glue for that sensor would have been nice. All in all it's a good kit with a lot of tools.

Farley: So recently my S8 battery began bloating out. Busting the seams of the case. I wasn't ready for top of the line phone, and really liked the s8 so I bought a refurb for pretty cheap. Then I came across this product, and thought why not give it a go. If it doesn't work or I mess up my old S8, not a major loss. If I could get it to work, then I have 2 phones for whatever reason. Directions were easy enough to understand. More than enough proper tools are included in the kit. Including a new battery and an adhesive template film that was super easy to use to reseal the case. The whole simple process took me about 45 minutes as I took my time to do things right. Only other things you may need are a good work space, maybe a microfiber cloth to work on, another to maybe clean any previous glue away, a blowdryer or heatgun to help loosen up the glue, and maybe tweezers or a magnet to help grab these 14 tiny screws. All said and done and the phone is back together and working fine. It may not be as water resistant as the seal isn't quite as good as new, but not a big deal. The big question is how is the battery life. This battery is just some no name knockoff, so I didn't have high...

Amazon Customer: After researching for a replacement battery for my galaxy S8 I decided to go for the HDCKU. The kit is complete with tools that I didn't even need to perform the task. The old battery was holding the charge for only a couple of hours. This new battery lasts approximately 11 hours. I would not call this an easy task though. You have to use a heat gun or hair dryer to loosen the glue and it takes time to do it. Some videos in go for the bottom of the phone and this is where the glue is the hardest. After spending some time on it without success I went for one of the sides of the phone where the glue is the softest and it worked great. I was able to detach the back glass to about 95% before I shatter it by applying to much pressure with the metal tool. This happened at the top of the phone where the glue is as hard to get out as it is on the bottom. During this whole process I was applying heat with the hair dryer to the point that I could not tough the phone. My recommendation is to also buy the back glass as well and make sure that it comes with the adhesive kit. I cycled the battery 5 times from full charge to no charge at all and it certainly improved the efficiency of the...
