Definitely a good battery. I have an IPhone XR, so the 8 year old battery it came with wasn’t doing well. This newer one works a lot better When i replaced it, the old battery was at 74% capacity. When it’s below 80%, it makes a lot of apps just freeze or suddenly stop working for a bit. In my case, it was mostly Google maps while I was using it to get around. I only replaced it a few hours ago and I’m already noticing a huge difference. All my apps work, and it appears to be charging faster. Of course, Apple does have a notification now when I open the battery health saying it’s not an “official Apple battery” which doesn’t bother me. I’d rather buy the same part for $30 versus $90 cause it has the Apple logo on it. Just something to keep in mind if it will bother you, as this will happen with any Apple tech when you don’t install an official Apple part. For anyone who hasn’t done this before, you will need a heat gun of some kind (some other reviewers used hair dryers, I used a heat gun from a mechanic friend) and a thin piece of flat metal to get the screen off. Absolutely take your time with this, cause if you don’t, you will break the screen, heat gun or not. There are also cables behind your screen that connects to the motherboard so be careful of those when pulling it off. Also, if you have it, use some rubbing alcohol and q-tips. There is some pretty serious glue holding the battery in place, putting the q-tips soaked in the alcohol along the edge will help soften the glue/degrade it so it will be easier to pop the older battery out. Admittedly, you could technically use the heat gun for this as well, but I’d advise against it since having it directly on any electronic battery can end badly. My only complaint about this product, is the cable that connects the battery to the motherboard is about 1-2mm too long. This makes it difficult to get in, but the seller does provide some really good metal tweezers that will help with this a lot. Overall, it’s a good product. Also cause I saw another review mention it, any battery you get for a replacement part will be charged around 50%. This is just a safety/law thing in the states. If they keep them fully charged they are more likely to get damaged from lack of use while they are in storage/inventory. Doesn’t just apply to phones, but laptops and various other lithium batteries. Also, for anyone getting rid of the old battery, staples (at the time of writing this review) will take it and recycle it for free as part of their tech recycling program. This includes bloated batteries (they just need to put those in a separate bin due to the fire hazard, so make sure to give it directly to a staff member if it’s bloated). The daily limit in terms of tech recycling at staples is 20 items and you can get points for it that go towards coupons (if your into that). Highly recommend making sure that any lithium battery is disposed of properly due to the chemicals and fire hazard the old ones can possess

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!

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.

I bought a different battery that was supposedly highly rated and cheaper but it immediately had significant issues. This one seems to be the real deal. It’ll still show on your phone that it’s not an authorized replacement but it charges fast and so far actually seems to last as long as they’re advertising.
