21800mAh Super Capacity Battery Compatible with iPhone 11 Pro Max, 0 Cycle Li-Polymer Replacement Battery for iPhone 11 Pro Max, with Professional Repair Tool Kit

The battery is working great, good for the price. The installation method is easy if you know what you're doing. no hot battery, no drain, no leak.

I fully charged the battery and worked fine after that. The lcd screen I had purchase was also draining the battery because it was damage.

EXCELLENT battery! I was nervous at first doing the installation myself, but it was actually pretty easy and straightforward (with the help of YouTube). I let the initial charge (around 65%) go down to about 20%, then charged to full overnight and THREE DAYS LATER I am at 66%. Even after a few phone calls, text messages, data usage, and watching YouTube videos..66%! Definitely worth it.

Bought this battery replacement for my wife's iPhone Xs. Battery was fine it worked as intended and have no issues. Taking away 1 star because the adhesive that goes on the back of the battery was not the same style apple uses. And the there was no instructions on how to use the adhesive. But other than that it's fine and worked.

Perfect fit. I was concerned with short life at first until I read the instructions in the listing. Be SURE to fully Charge and discharge 3 - 5 cycles to get maximum capacity. I just left the flashlight feature on. After a few cycles, the light would last several hours at the brightest setting.

These things last forever, they seem to have issues charging and I don't know if that's just because of my controller but it takes very specific cables to charge my controller now (chromebook chargers, and other high power chargers). My girlfriend's controller does not have this issue so I do not know the cause, just wanted to note it.

As other reviews have mentioned the claimed 13000mAh capacity of the battery is false advertising, the actual mAh is less. It's probably the same as a standard battery for whatever model you getting a replacement for. I didn't see any reviews for a base Iphone 6, but my wife refuses to let hers go and the battery was completely bad and wouldn't hold a charge at all. The swap was very easy and installation was a breeze took me like 10 minutes to open the phone and remove the old battery/screen and then 5 minutes to put it all back together. The phone's battery now is basically back to good as new which is why I'm giving 5 stars despite the false mAh rating as I knew that going in.

Comes with everything you need, battery seems to work well but we will see how long it lasts. I only deducted one star because the instructions are atrocious and the adhesive does not come pre-installed and you will have to figure out this step yourself.

La batterie de ma switch était morte, je l’ai remplacé avec cette batterie et pour le moment tout fonctionne bien facile à installer

Buena calidad

Working great for over 3 months so far. Works well

It’s been months and all is ok. Have steady hands, no distractions. White background for repair. Do a YouTube and make sure it’s for your phone. Easy to do. Once you’ve done one, you’ll never use service again. Comes with all the tools (which I’ve used for other repairs requiring tiny tools)

This kit and replacement batter did the trick. Used it to replace the batter on my Nintendo Switch Lite. I'll admit that it was really tricky getting the original battery out, as it's completely glued to the console, but the kit itself couldn't have helped with that. Once I had the new battery in my Switch is back to running for multiple hours which I'm very happy about.
