Review: 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.
Review: 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
*by A***R on January 2, 2026*

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.
