(New Upgrade 23900mAh Battery Compatible with iPhone 11, Super Capacity Battery Replacement Compatible with iPhone 11, with Full Tool Kits-0 Cycle High Capacity-24 Months Service

For the momemt I'm giving the Luuzkla battery 5 stars. It included the tools needed to upgrade the PS5 controller, as well as instructions. I still recommend watching some videos online. The last *pop* of the 2 halves of the cover took a lot of force to unclip. - Battery took a loong time to charge, but it also is lasting a lot longer. I would say about 80% longer than the OEM battery. 8-10 hrs now vs 5-6 hrs. Keep in mind, this replaced a 3 month old controller battery which was supposed to be the newer bigger better Sony design. I have to admit, the older OEM controller that came with the PS5pro a year ago, has better battery life than the newer chroma teal controller, which was surprising. I will eventually replace the OEM battery as well, but it's still getting close to 7+ hrs on a charge, so no hurry there. I wanted to wait on the review until I had charged it a couple of times. (I have bought batteries in the past that worked great on the first charge and then totally died on the second charge.) No problems with this battery so far. I will definitely update this review if anything changes. I would recommend and buy again.

These batteries are great! Bought and installed them in my PS4 controllers that were not holding a charge anymore and always needed to be wired to play with. They are nice and last a long time between charges. I can play ESO all day and not need to charge or swap controllers.

Literally has everything, even the glue to glue the phone back together after the repair. I was being stingy and debating on this one or a cheaper one, but I’m very happy with my choice. Battery works as performed. It was easy to replace. I was watching a YouTube tutorial by Ifixit, no experience and I was able to complete my own repair to the phone within 30 minutes. They literally had everything in that video even the extra screwdrivers.

9/25/25- Luuzkla 19800mAh (2025 New Upgrade) Battery Compatible with iPhone 12 This was the very 1st battery replacement for this phone. After install, I do not see a battery warning of any kind unless I go to BATTERY in Settings and look in Battery Health. It says it cannot determine the Battery Health. *The screen removal suction cup that comes with this kit is WAY too weak to remove a well-sealed iPhone screen. I ended up using my dash Cam suction cup, which worked much better. *This kit does not come with a stand-off screw remover, so you will not be able to remove the Haptic Engine and Sim Card Holder (which seems to be unnecessary anyway). * It is HIGHLY doubtful that this battery is actually 19800mAh. I haven't measured it, but it's probably closer to 4000mAh (which is a total guess). I just put the battery in, so I will report back as soon as I have any info. So far, it's MUCH better than the failing OEM battery and took about 6 hours to charge via cable, (not wireless) from completely dead. *Battery comes half charged. *ADVICE... After install, run battery all the way down until your iPhone shuts off and leave on charger 1-2 hours AFTER fully charged. Do this a few times to set the battery memory and to see if your phone and battery BMS are working correctly. English instructions poorly worded and hard to understand, and it basically tells you to watch a YT video for instructions. I've replaced older iPhone batteries before, and I must say, this was by far the toughest one to do even after watching several videos. At one point, I almost wrote off my phone as I just couldn't get most of the connectors to pop back on, especially the battery connector. I never had this type of issue before this repair. I also followed a written addendum they included that tells you how to place and reconnect the battery, but it still took countless tries. Finally got it all together and powered up to a completely grey screen, which scared the bejesus out of me. Re-tried a power up once more and it worked. YAY! The kit comes with the 19800mAh battery, 3 different screw drivers (which should be color coded), a pick, an angled-pair of electrical tweezer, a plastic pry bar (Spuger), a suction cup (that's too weak to pull the screen off), adhesive strips to hold down the battery and a replacement screen gasket. NOW I GOTTA DO MY WIFE'S IPHONE 12... UGH!!! 10/4/25 UPDATE- Still working great. Charge seems to last a bit better after a few days of training the battery (charge to 100% and use all the way til the iPhone shuts off by itself). Was worth the money, but again... install was not easy.

Has everything you need to get your phone working again. The battery health is back to 100% on my old iPhone 6sPlus. The instructions…Dont even try to read them lol. Plenty videos on YouTube for a very concise repair. I used all the tools except for the smallest screw driver and the adhesive that goes along the border(i left that out in case i have to open it again) Be mindful of what you plug your phone into whether it be an outlet with USB or a crappy gas station car charger, as some of those exceed the charging voltage and can shorten the life of batteries or make them overheat. This replacement has a limit of 4.35V and the outlet on my nightstand charges at 5.1V😬doesnt sound like much, but repeated cycles will def reduce longevity and battery stability. Use your original power cube or a reputable brand and cable. (my iPhone 14 from 2022 is at 80% even with “optimize charging schedules” or whatever Apple calls it) This replacement is basically the same operating voltage as the Apple one 3.8V (new one being 3.82V). Time will tell if it holds a charge. Thank you Luuzkla! 🤓

The screen adhesive is thinner and less sticky than the original so it’s doubtful that the phone is still waterproof; but the battery works great and holds a charge (so far).

Easy to install & holds charge well.

I installed the new battery in my iPhone 11 successfully. I then ran it all the way down below 10% and charged to 100% a couple times. The outcome so far: It stays at 100% for almost two hours of screen time, then starts dropping fairly rapidly. I would estimate that it lasts for about 6 hours of screen time, which is probably about the same as the original iPhone 11 battery (which was 3110 mAh--NOWHERE NEAR the 23,900 mAh the seller claims!). Honestly, I was hoping a brand-new battery would have 2 days of normal use in it, since it'll go down from here, but it doesn't. Two notes on the self-installation: (1) It is very difficult because the original (and new) battery is held down with six adhesive strips. YouTube videos show applying isopropyl alcohol and then pulling these strips out, but in practice, this is totally impossible. No matter how careful you are, they just break. All six of them. Thus, removing the old battery requires jamming a tool under it to forcefully separate it from the iphone back casing. I succeeded in this but very nearly damaged the front-facing cameras in the process. Those cameras, plus a separate plastic piece came loose. I surmised the plastic piece sits behind the volume buttons and put it back there; everything seems to work now. But I feel like I got lucky. (2) The new battery comes with very brief and badly translated instructions that do NOT cover most of the process; the instructions only cover a few parts of the much longer process. They refer to a video but give no indication of what video that would be or where to find it. You just have to look up the process in general on YouTube. The videos there are pretty good, but it remains a difficult, delicate process. It starts with prying the screen off the phone with a razor blade! (Blade not included--the kit has a suction cup instead which doesn't work at all.) Be aware that the YouTube videos aren't specific to this particular replacement battery kit, and some aspects (especially applying the adhesive to the new battery and applying a sealant ring around the phone just before you close it up again) are explained nowhere and are far from obvious. You basically have to just do your best to figure it out. Again, I succeeded, but it was disappointing and stressful that I had to improvise! I gave it 2 stars not 1 because, in the end, it works, and the included tools were good, apart from the suction cup. Now that I'm done, the phone works fine. But the installation process was much worse than necessary due to lack of instructions, and the battery capacity is much, much lower than advertised.

Exelente rendimiento y precio
