Works great and like a new controller after install
Super easy to replace the battery in my dualsense and the new ones work even better than when my controller was new from Sony. Full charge I get about 8 hrs playtime with vibration on. Should have done this a year ago instead of suffering and recharging every 2 hours. YouTube has lots of tutorials on how to pop off the case. Once that’s one it’s super easy to plug the new battery inside. I also like that I have a spare one for when my other controller needs a new battery too.

Works well; has been reliable
Spouse replaced this battery for me in my iPhone 7 Plus; I couldn't have done it. It is very painstaking work and involves tiny, tiny screws. It is, however, working just fine, so no complaints

Very Complete Kit
This is a very complete kit. This is the fourth phone battery I've replaced (first in this phone). This was the best kit I've purchased. Besides the battery, the kit contained all the helpful tools, properly sized screw drivers, battery adhesive, and a custom cut adhesive to reseal the phone. It is a very thorough, well done kit.

Great product coming from professional repair technician
great product I have run a repair shop for one year and I alway get this one but as professional repair technician highly recommend this product as always I don't recommend using the cheap tools that any part come with but they work but that's to expect but they work but that might just be cuz I use professional tools my customers come in and says my battery in a day never gets bellow 80% in one day 100% great product

Everything is great EXCEPT Battery Life
I bought this, fast delivery, excellent packaging, way more items provided with the package than I would need but I'm appreciative of that. However, when you buy a new battery you'd expect it to last at least a full day after full charge but this is not the case here. After replacing the battery, it went from 100% to 16% (at the time of writing this review) while I was using the phone mostly screen, no calls, GPS, Bluetooth or anything requiring more battery output in less than 5h 30m. Only screen time was used, not on the brightest settings. My old battery lasts almost the same time as this. Absolutely no significant difference between the 3 year old battery and this replacement one.

Definitely improved my battery life
Was it way harder than expected to replace this on my own? Absolutely. But following some youtube tutorials, I was able to do it with minimal issues (fyi, it's very easy to warp the back cover of the Galaxy S20 FE when scraping the glue off. The cover doesn't sit perfectly flush anymore in one corner, so you may want to order a new back cover as well instead of reattaching the old one. Note that this does not include the adhesive for the back cover, so you'd need to buy that separately regardless). My old battery would get down to about 30% by 1pm with heavy use. Now, at 3pm with heavy use it's at 55%.

Worked to help me keep my old phone alive as a spare, while I sent my new phone off for repairs
I used this to bring my old Pixel 3 back to life. The battery was bulging and I had given it up for dead several years ago. Luckily I kept it in a drawer. Anyway, my *new* phone's battery died and I had to mail it off to be repaired. So I ordered this battery kit, and installed the battery and sim card into my Pixel 3, and everything's good to go. I've only been using it for a week, so I am not sure if I'll eventually see the same loss of battery life that others have mentioned, but I did notice in the "instructions" (use youtube instead) it told me to completely drain the battery to ~8%, then charge to 100% on a SLOW charger (1amp). It said to do this EIGHT TIMES before using the phone normally. This theoretically conditions the battery and helps it live longer. Well, I didn't have time to do it 8 times, but I did my best to do it 3 times. Hopefully that's enough. I will say that the trickiest part is just taking the phone apart, but it isn't nearly as bad as I was afraid it was. The included screwdrivers were crap-- I happened to have a kit that included tiny screw drivers, so that was good. Aside from that, just watch youtube tutorials for swapping the battery and go nice and slow. I plan to keep my pixel 3 around for years to come as a "spare" for if my husband's phone or my phone need future repairs, and we need to just swap the sim card to the pixel 3. I know eventually the pixel 3 will be too old to do anything, but as long as it can get emails, texts, and place phone calls, I can still use it.
