15500mAh Super Capacity Battery Compatible with iPhone 12/12 Pro, 0 Cycle Li-Polymer Replacement Battery for iPhone 12/12 Pro, with Professional Repair Tool Kit

It was extremely easy to install & fits perfectly on my New Nintendo 3DS XL. It works exactly as intended, and the quality is excellent. I also appreciate that it came with a tool kit. It was definitely worth the money, especially since my original battery was bloated & could barely hold a charge anymore. After using this replacement for a while, the difference is like night and day. I can finally enjoy longer gaming sessions again.

I bought this and it did work well and it was a good price, it fit into the compartment. The tools included were very helpful and much better than some I had that size. My problem unfortunately ended up being the charging port, but the switch lite at least was able to turn on again after I installed this new battery. It wouldn't do anything due to the error code for the port. There are plenty of video tutorials on YouTube that walk you through replacements for switch parts. Con: there was no adhesive for the battery so you will need to buy that separately or it will jostle around inside the device.

**Updated after 30 days. I don’t have a bad outlook on life and hate is a word I rarely use. But there’s not another word I can think of for the feelings I have towards the seller. That should be all the review you have to read. But if you’re wondering. Everything is 10x worse now the phone won’t stay on more than 3 minutes. Will be removing AND paying to mail it back to the seller out of my pocket with a letter what to do with it and his warranty.**.(Original review follows) Battery installed Easy that’s about it. Fully charged it like they suggested. I tested it to make sure it would turn on. Turned it offI left it sitting overnight and was dead the next day to the point that it wouldn’t come on. It gets so hot can’t touch it if the screen is on for more than 3 minutes. Charges incredibly slow, so don’t know if I got a defective battery or what but I do know I can tell you it’s not even close to 15,000 MAH, honestly I was expecting over 5 but no it’s same as a factory battery. Also Phone keeps rebooting. All the time it took repairing my phone my return period ended and I’m stuck with a defective battery.

I'm sure it's not nearly the mAh advertised, however it works great and my battery lasts a long time. No issues with installation.

Installation was straightforward, though I referenced online visuals for guidance. The battery fit properly; however, the connector clip on the battery was slightly longer than the OEM part, causing a minor fit issue. The device reads 100% capacity and did not overheat during charging, contrary to some reports. While I question whether the stated mAh rating is accurate, battery life has noticeably improved compared to my previous battery.

These batteries have been very durable so far. The build quality feels solid and reliable, and I haven’t had any issues using them. They provide a really good amount of constant usage time, which is exactly what I was looking for. Overall, they work great and feel like a good quality upgrade. Definitely satisfied with this purchase.

The battery life leaves a bit to be desired. It leaves a bit to be desired, especially compared to the stock battery, at least when in sleep mode. That said, it sure beats having a dead battery! This definitely works in a pinch. This was a pain to install. Part of that is Nintendo's fault, since they glued the battery in, but this battery was also slightly large for the slot it went into.

I've bought about a half dozen of these little kits and I'm happy to say that these are a major upgrade compared to the tired, old factory PS5 Dual Sense controller batteries. I've never had a single issue with any of these batteries, they last so much longer than the factory ones that I even replace BRAND-NEW PS5 dual Sense controller batteries with these batteries! Easy to install and a great value as long as the prices stay the same. Will continue buying these as needed the tools that come with the kit are a nice addition I use them all the time now.
