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

The battery charge holds up really well. The fit of the battery was perfect. No problems at all. Recommend to anyone needing a new phone battery

update: played 5+ hours of youtube via safari without issues. battery % says there is around 43%, but i would take that with a grain of salt since the phone isn't showing the real %. not bad though.. just make sure you fully charge the phone for a few hours before using it if you need a full charge. -.-.-.-. update: using this iphone with the new battery, i can use the memo app to record 6+ hours so far. this is my intended use so that's great. I think the phone is just not showing the correct battery %... because sometimes it will sit at 100% for days.. I think it's really draining and not showing the actual %. because if I use it after not using it for a few days, the charge will drop FAST... but once I charge it.. it'll drain slow.. like it should normally. so i think ios is just not showing the correct battery %. makes sense since this is a 3rd party battery and apple doesn't ever play nice when it comes to repairability. --.--.-- the package includes everything you need which is great. watch a youtube video before or while you're working on it and it's super easy. be careful and go slowly. i did a full charge and then a full discharge. the battery lasts a very long time when the phone is idle and airplane mode turned on. I don't have a lot of applications so there aren't a lot of background tasks going on. but that's great for me bc i use this phone very rarely and it's nice to come back to it and it hasn't lost a lot of charge. the bad is that the battery, while the phone is being used, doesn't last very long. NOW I believe this is not really the battery's fault... but rather that it's just an old device... unsupported software that apple probably made the iphone work worse so that ppl buy a new phone. BUT, it is what it is and you cannot expect this phone to lasts HOURS of use. if I can get two hours of use, that's a win, imo. and if you need it to last longer... just connect it to a battery pack. I'm able to play youtube for a few hours on this phone with this battery replacement. that's pretty good imo. ofc I'm having to use safari bc no apps are supported anymore, but it works for now. the battery isn't really 19900mAH. the company should just tell the truth, tbh lol. ig they think it's a selling point.

great product. had all the tools needed. the only drawback there were no instructions. Simple enough i figured it out.

I bought this kit to replace my iPhone battery, and overall it did the job. The instructions that came with it were a bit vague, so I ended up using a YouTube video as a reference, which made the process a lot easier to follow. The only downside was the suction cup—it felt pretty weak and didn’t stick as well as I expected. That said, it could have been user error on my part, so I won’t knock it too hard for that. Aside from that, everything else worked as intended. I successfully replaced the battery, and now my phone’s battery health is showing at 100%, which is exactly what I was hoping for. Definitely worth it if you’re trying to save money and don’t mind doing a little DIY.

Works well very easy to replace and it fit right into the phone i was able to fix my boot loop pretty quick and easy I will say it’s only for temporary repairs I would use the Battery as a complete replacement since it’s not an official battery there were no issues with other components getting corrupted but it does overheat after a few hours of using the phone but that’s completely normal with the model

Excellent battery replacement for my N3DS XL (SNES Version). I loved the price vs. quality after use it for 2 weeks and I can say that I'm very satisfied with it. The installation is extremely simple to perform since you only need to remove the back cover (don't forget to remove the stylus and any games you have prior removing the cover). The size of the battery shown no issues and it was a perfect fit. The tool kit was perfect as I only needed 1 of the screwdrivers and keep the others for other projects. As recommended by the website, you must perform 3 to 5 complete charge and discharge cycles, and let me tell you that the discharge was a looong because even when the red light started bliking indicating that the battery was almost out, it took around 1hr to 1.5hrs to turn itself off (I got tired of playing before that happened, but left it in the gameplay loop). I used the battery by playing MK7 with full brightness, medium sound volume and the wifi on so it would drain the battery faster and still gave me a good 6-7 hours practically none stop (I didn't closed the console to avoid having it in standby). Overall, this battery's functionality delivers what is advertised on the detail page. Great price, great fit, and definitely a future next purchases.

This was one of the simpler phone battery replacements I've had to do, and this product makes it as easy as possible with the iphone se. After removing the old battery, the installation of the new one tool less than 10 minutes. Everything is included for the installation, including new adhesive for the battery. A phone that was lasting about 4 hours a day is now at 97% after 24 hours of the new battery. Big improvement!

I used the kit to replace the battery on my old iPhone 6 because the OEM battery somewhat exploded to the point the front of the phone buckled! For around $10 I could see how difficult it is to replace a battery in the phone. It turns out it is not very difficult at all! The instructions with this battery are pretty bad. I can't understand with today's technology of translation, and also willing people to translate, that these instructions are never very good and often misspelled. On to the actual kit, this worked out pretty well overall. Found a good video online that explains exactly what you need to do to take out the old battery and put in the new one. The only issue I had with this kit is there are about three parts that are unexplained on how you would use it and they are all in my second photo. Possibly the blue thing is used to wedge off something I'm not sure and the smaller blue cellophane thing I am sure is used to glue down the new battery, but I didn't need that since the old glue stayed in place. The larger cellophane I believe is used to put a seal around your phone to seal it back together. I didn't see a seal when I opened up the phone so I figured it has worked this far this way, why change it. Other than that, and the battery installed fine and is charging up perfectly. So my advice is if you have a phone that has a bad battery, take a chance and try this out.

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.

Battery was fine, although the installation process was difficult as I had never worked on an iPhone before this.

Working great for over 3 months so far. Works well

They should do a better job of showing you where to find instructions, but I changed my battery and am happy with the results. Also keep in mind this is not a genuine Apple product and will register as such

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)
