Upgraded Battery for iPhone 11, High Capacity Replacement iPhone 11 Battery A2111 A2221 A2223 with Professional Repair Tools Kit

Battery lasts very long based off of my first charge. Certainly longer than my 75% battery health iPhone stock battery. Takes awhile to charge but that’s a trade off I’m willing to take. Tools and seal that came with it worked well. I used an online video from iFixIt instead of their instructions cause it’s easier to follow but the seal applying sections was useful in the guide. Overall a good replacement option so far.

I’m always a little leery when you read about these iPhone batteries and they claim a long charge life, etc. but I will tell you this battery actually is better than the original battery. I have power all day even if I’m using the phone most of the day. I think this battery is better than the original.

I would rate the skills needed to remove the old battery and install this new one as “proficient/advanced” and the task itself as 6/10 for difficulty, only because you may have to improvise if it doesn’t go according to plan. It took me a little more than an hour after I watched a YouTube video tutorial and read the included instructions. Some of the steps and some of the photos in the instructions are not clear so you really need to watch a good video. The two hardest tasks are 1) opening the phone, and 2) releasing the old battery. It was hard to use the suction cup, squeeze the sides of the phone AND wedge in the metal piece, all at the same time. The metal ring on the suction cup is useless because it’s a thin gauge wire and it opens when you pull on it. I ended up just squeezing the sides of the phone and wedging the metal piece into the bottom seam. I scuffed the phone slightly but you can’t see it once I finished and put on my protective case again. Removing the four adhesive tabs did not happen as shown in the video. I worked very, very slowly and all four still tore, leaving the adhesive on the back of the battery, still securing it to the phone, so I had to pry up the battery. The blue plastic pry tool (included) was useless and broke immediately. If you need to pry up the battery, you may need something that’s made out of sturdy plastic or wood and is very thin, like a clay sculpting tool. You might be able to use a metal flathead screwdriver if you put tape around it. It can be difficult to pry up the battery because there’s nothing to use as a leverage—you don’t want to damage any internal phone components, you don’t want to bend the metal casing, and you don’t want to puncture the lithium ion battery. If you have any doubt that you won’t be able to find a safe way to pull up the old battery if the adhesive tabs tear, then I wouldn’t try this installation. I’d have an Apple tech do it. As far as the battery charge: I charged it to 100% and after an hour of just reading articles and some light texting, it’s down to 92%. So far, I’m satisfied with this product.

As of writing this it’s currently Sept. 24, 2023. I got my battery replacement about 7 hours ago, and finished 5 hours ago in the evening. I plan to come back somewhere in the middle of October to see how the battery holds up. Right now I’m trying to calibrate it by charging it to 100 and keeping it there for 2 hours, then making it die and then charging it up to 100. I do have to say though, it charges pretty slow but hopefully that means it’ll also last a long time. I also noticed it doesn’t get warm at all, unlike my original apple batter whose capacity was 78%. Installation was not too difficult following iFixit’s tutorial, but the screws are really small and I’ve lost 2 of them so I need to watch out for drops.

Battery install went fine. Seemed to work well on the test startup. The problem came when I tried to disconnect it to put the seal on the screen. The GARBAGE connector ripped off (I’ve repaired hundreds of iPhones in my life, this was not user error) leaving the desolated pins jammed in the board. In removing them, the jack was damaged and the phone is now a total loss. One $40 battery with one terrible solder joint destroyed my entire phone. Avoid at all costs, you will absolutely regret this.

Worked fine was pleased but then died 6 months after I purchased and paid to have it installed.

All good

I've installed quite a few batteries over the years but the iPhone 8 battery is not as easy as most.I used the iFixit guide which is very well written and concise albeit not for the first timer. There are many places in which a mistake will cause you a whole lot of hurt. Be careful and take your time.This battery kit is almost perfect except it is missing the "standoff" screwdriver. I used a very flat flat-head screwdriver that worked but it slipped easily which caused the blade to come dangerously close to stuff that could be damaged. It would have been nice if this screwdriver was included but for $18, I can't complain. The adhesive seemed to fit pretty well although was not very wide on the sides. I don't know if this is the way it is supposed to be or was just a inferior product. No way to check how good the water proof seal is.To conclude, this kit is perfect if you want to replace your own battery on an iPhone 8. Very pleased.
