I Did It!! You can too!
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!

Not Easy But Doable
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!

Kit was OK, but instructions were not.
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.

Excellent battery to give life back to your N3DS XL
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.

Drains quickly for 13 pro max
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.

THE ONE!
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.

Tight Fit, but works good.
Good replacement battery for the money. Fit was quite tight. Just barely fit in the space for it. It also seemed a slightly thicker than the factory battery. At first I was concerned that it might keep the screen from fitting all the way down, but it ended up working just fine. I broke the screen when trying to get it off (my fault - no fault of this battery manufacturer) Ordered a replacement screen, and put it all back together. So far, it's charging fine, and seems to last a while. Worth noting: The cable that connects to the main board was just slightly too long, so I had to adjust where the flex cable bent. But worked out fine. Overall, would buy again. Note: I also got this same battery in a different variant for my daughter's iPhone 14. That one was great. Would give it 5 stars. It won't let me do a separate review for that one.

Pésima calidad en la pila y herramientas, la pila no funciona correctamente y las herramientas que venían no eran del tamaño de los tornillos.

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)

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.
