GREEN FUSION Only for Mi 9T Replacement Battery, BP41 Battery for Redmi K20 and Xiaomi Mi 9T, 4000mAh, with Installation Instruction & Repair Toolkit

I was away visiting family when I noticed the back of my Samsung Galaxy S22 Ultra was separating from the rest of the phone, the dreaded battery bulge at play. It's a few years old, and I could have replaced it, but I wasn't ready to do that, as the phone does everything I want, it's set up just the way I want, I'm really happy with it, and it's due to get its last update next month, One UI 8.5. So given all that, I decided to buy this kit and replace the battery. The kit comes with everything you need, the battery itself, as well as all the tools you need to do the repair. It does take patience, as I read where a number of people cracked the rear cover and had to buy a new one. So with that, I took my wife's hair dryer and heated up the back of the phone, and then, started where it has already begun to separate and carefully worked my way around. I had to use the hair dryer a couple of more times to soften the adhesive and then, finally, I was able to pull it free. The instructions guide you for the rest of the disassembly process, and if they're unclear to you, there are several YouTube videos available which walk you through the disassembly. You just want to take your time, be careful, and make sure that you don't lose the screws that you have to remove. Getting the old battery out is another process, as they also use adhesive on the underside of it, but the kit has a nice tool to aid in removal. The new battery comes with adhesive, so you simply peel off the protective layer and put the battery in place. Then you essentially follow the directions in reverse to put all the cables and screws that you removed back in place. Before installing the back panel, I fired up the phone to make sure everything worked, and it did. The kit also contains new new adhesive for the back panel, and you just want to use care to position it in place. I was very careful at this stage because I wanted the phone to look perfect just as it came from the factory, and it did. All in all, because I was patient, didn't rush, and took care with the repair, it took an hour from start to finish. My advice is to fully charge the battery, plus leave it on charge for 2 additional hours before first use. This kit has everything you need to replace your phone's battery, and anyone with reasonable mechanical skills and patience should be able to do the repair. I highly recommend this kit because of the quality, instructions, and completeness. For about $20, rather than the $100 and a day or so at the repair center, you can do this yourself.

Beyer Beware Actually disappointed. It's not even 5 month and my battery goes from 100 to 60%, then just 2 hours of browsing the internet. It's a bigger battery it just doesn't hold up to the old battery that I replaced it with. Worked really first but then as the weeks go by I noticed it doesn't hold a charge as long not worth the trouble all the money unless I Got a lemon. Not happy

This battery replacement did exactly what I needed it to do. My S23 Ultra was dying fast and struggling to hold a charge, and after installing this, it feels like a brand new phone again. Installation was straightforward, especially with the included tools. Everything fit properly and nothing felt cheap or mismatched. Once installed, the battery life improvement was immediate and noticeable. It holds a charge all day without any issues. Great value compared to replacing the phone or paying for a repair. If your battery is going bad, this is absolutely worth it.

Bought this for my Samsung S23. It was my first time changing a screen. The kit made it super easy. It fit perfectly and looks great. Touch screen performs as it should. Replacement quality is top notch. Great value!

Bought and installed, better than the used 3 years original one. The capacity of mine is not as much as the design, so dose not work long before next charging.

Old phone battery ballooned up and pushed the glass back of the phone off so replacement was easy without most of the tools in this kit. The precut adhesive and the small pry bar are very much appreciated though. Battery fits fine and the phone works again. Battery life seems to be the same as the old factory one.

Installed this in my wife's phone and it brought it back to life. The battery doesn't really last very long though, so I am doubtful about the claimed capacity. The replacement back cover was great, and came with the adhesive tape already applied around the edges. Update 1/2025: battery dies within an hour. We have to keep the phone plugged into a power brick to be useable at all. Probably worse than the super old on this replaced.
