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

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. UPDATE: the battery still seemed to discharge quickly until I let it discharge slowly before recharging. Now, instead of going to zero overnight with nothing on, it goes to 45%. Will continue to monitor.

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!

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.

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.

Well, the installation is not easy. My husband fixes a lot of techy stuff but this was a challenge. It took about 2 hours, a blow dryer and was pretty stressful. But day 2 with the new battery and it is holding a charge better than my old battery!

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.

The Battery for the iphone 14 plus work great. The only reason im giving this product a 4 star is because of the adhesive tape for the battery and the back of the phone wouldnt peel off onto the battery or the back side of the phone when your trying to apply.
