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

rewriting my review because more testing showed me that this battery, in my short time with it, is working very well.first off, i don't think the iphone displays the correct %.. I've had the phone idle for days and it stays at 100%, but then once I use it... it'll drop 30%+ within ten minutes. so I believe because it isn't an official battery, ios cannot reflect the correct % which isn't a huge deal, but something to keep in mind. if you're going to be spending the day with it.. just make sure you charge it for a few hours even if it says it's at 100%.i was able to record, using the memo app, 9 hours of audio recording when starting at 43% charge. i'm also able to play a good 12+ hours of youtube video via safari. i think it's probably because safari will only play 360p video since the iphone is so out of date.keep in mind, this phone can't use any apps because it doesn't get updates anymore and apps don't support it. only safari works for me. without safari, this iphone would be almost completely worthless. i am however using it for audio recording via the memo app and that works fine.depending on how long this battery lasts, i may buy another for my iphone 6s and iphone 5s.

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

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

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

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.

After watching some YouTube videos (multiple times) I finally pulled the trigger on replacing my iPhone SE (1st gen) battery.It went amazing well! I had a few minor issues: pulling out the adhesive strips (yup, they broke) and the video addressed how to deal with that. With some blow dryer heat and some gentle prying, I was able to get the old battery out. Yay! The other issue was knowing which screwdriver-type tool to use with which screws. The screws are incredibly tiny. Repeat: incredibly TINY. 😕I’d say the reassemble process took more time than the disassemble time. Those teeny tiny screws were challenging (along with figuring out which tool to use).After the successful reassembly the new battery showed it was 65% charged (out of the box). I went ahead and plugged in the device to fully charge to 100%. GREAT news, the battery has only gone down by 2% after 4 hours. Woo-hoo! With the original battery it would go from 100% to 20% in a matter of 2 hours ☹️. And then from 20% to zero % within minutes.I am so pleased that I now have a reliable device that I use mainly for reading ebooks and for music, plus some random apps that I got for free way back when.And a side note, I’m a female in my late 60’s, and am quite proud of myself for my accomplishment.If I can do it, you can too!

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.

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.

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)
