13500mAh Super Capacity Battery Compatible with iPhone Xs MAX, 0 Cycle Li-Polymer Replacement Battery for iPhone Xs MAX, with Professional Repair Tool Kit

So far so great! First time replacing controller batteries but i have some mechanic experience with both electronics and vehicles so this was a breeze. Found a useful youtube video that stepped through all the easiest order of doing the swap and was done in 15 min. The original batteries say they're only 1560mAh and a lower charge rate so I'm a little worried about overheating but overall reviews encouraged me to still try these. I'll update again after I've put through the paces and got estimated run time for these etc.

Worked well to revive my controllers back to life. A nice little upgrade. Controllers seem to last longer now. Maybe it was just the degradation? 🤔

I got this and I noticed that every battery replacement kit looks the same. I thought it would be easy. What I DIDN'T DO, was watch the process on YouTube.The kit is VERY inadequate for the battery replacement process. I couldn't even get the SCREEN off and I'll tell you why later. But lemme start by saying, the instructions are not good at all. Then on top of that, they tell you to watch "THE" YouTube video, they don't HAVE A YouTube video.When you go and watch MOST YouTube videos, they have equipment that DOESN'T come in this pack and that equipment is CRUCIAL to making this process easy. To get the screen off, you will need:A more deluxe suction cup than the one they give youSome type of thin razor to pry the screen openA heating tray to warm up the LCDA syringe to drip some isopropyl alcohol into the display to loosen the adhesiveThose are the FIRST STEPS of most videos but guess what....... The kit includes NONE of those. I tried to use A HAIR DRYER because that's the alternative to heating the phone up but with the equipment given and the lack of instructions, the task was impossible.Even if you go to look into all the equipment I mentioned, you're better off taking the phone to a repair shop at that price, unless you wanna be the repair guy.This item had frequent returns for a reason, it's not worth it. If you still wanna buy it, watch THREE repair videos first, then find the other stuff you'll need on top of what they give you in this kit.

Install is a breeze and so far the charge time seems at least at par with a brand new gen 3 controller, possibly longer (don't have a new controller to do a control test against).

Been using the new battery for about a month now - battery went from needing charged several times a day to now basically lasting all day without needing to charge now which is awesome; whether or not its the claimed mA’s I’m not certain. Installation process took me a few hours and was a little challenging even with included items, and I am someone who is usually good with technology - one screw in particular on the taptic motor wouldn’t come off with any of the included hardware so I had to manually use two small nails to twist it up and out of position which was challenging; I didn’t have a small enough flathead. The ribbon cables on the battery itself were also a little difficult to position correctly and the pins didn’t exactly have a satisfying connection to reassure me they were in proper position. The glue underneath the original battery was also challenging to remove, so I did have to bend and warp it which I know shouldn’t be done so maybe have some additional tools around if you plan on doing this yourself - the youtube video I watched made it seem much easier as they used a pair of flat pliers to twist adhesive around them and pull it out that way - the ones included are bent so they couldn’t be used like this. Luckily the suction cup worked well - if the screen isn’t lifting like mine didn’t you just need more time heating and possibly a hotter setting; I probably heated my front glass for 5-10 minutes before I noticed any separation. I would recommend, just anticipate these challenges!

Finally one battery that comes in, not bent, packaging that doesn’t look like it was sat on by the person delivering it. Seems to work well, in my eyes, battery is battery, like road is road. Just don’t mess up the packaging.

Seems like it is a good thingy. Haven't installed it yet, can't tell how well it holds the charge. Overall, looks like a good product. Has many useful stuff in the kit.

Cons** Capacity not as advertised ** it is Actually 2600mAh, not 8200mAh.-Wires are a smaller gauge than OEM, but suitable for the application.-Extra wrapping on battery may affect performance.ProsBattery fits well in the controller.Battery arrived with full charge.Installation kit provides everything needed for installation.Actual Capacity is Larger than OEM.Battery is suitable replacement, but due to false advertisement and poor packaging (on the battery itself, case it arrived in is nice), I would not recommend. All the replacement batteries in saw at the time of purchase were at the same price point. I would purchase one without the deception.
