18800mAh (2025 New Upgrade) Battery Compatible with iPhone 11 PRO, Super Capacity Battery Replacement Compatible with iPhone 11 PRO, with Full Tool Kits-0 Cycle High Capacity-24 Months Service

This battery replacement was perfect for my Pixel 6a and exactly what I needed to bring it back to life. My phone was affected by the battery issue and post-update throttling, and I was charging multiple times a day before replacing it. The kit includes everything needed to do the job, tools, battery and connector that fits securely, and even a pre-cut adhesive template for resealing the screen, which made reassembly surprisingly easy. After securing it overnight with some rubber bands to apply even pressure, the phone screen is just as flush and solid as it was originally. While I can’t verify the exact mAh capacity, the battery life is dramatically improved and even better than it was before the throttling updates, with no system warnings or restrictions. After a few charge cycles, performance evened out nicely, and there’s been no overheating or swelling so far. There aren’t very detailed instructions, but with the included tools and a quick YouTube search, the process is very manageable. All in all, this is a great value and a solid solution if you want to restore your Pixel 6a without spending a fortune, highly recommended!

Works fine with my 2020 Note 20 Ultra. No msg. of non-Samsung battery after 2 wks of use. Holds and charges well, tho, questionable 9900mAh, think more closer to 4500mAh. A few words of caution of the installation process: didn't find double-sided tape with the package, had to use my own. Also, you will need this: https://www.amazon.com/dp/B0CRDG1XZ2 to get sort of watersealing. Cleaning the old gooey seal is the most tedious task in the process, but do it right if you want some watersealing afterward.

Samsung S23 ultra. As soon as I got it back from my phone guy I charged it to 100% then unplugged it to let it sit while I was asleep. It lost 10% just idle for 9 hours. Now today I started lightly using the phone since 9:00 a.m. It is now 1:26 p.m. and the phone is at 9%. Absolutely trash! Waste of time and money. This company should be required to pay for the labor wasted on installing their junk.

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.

Works great and my phone has been happier. The value seems good, I haven't had any over heating issues or expansion when going from the freezer to the ambient air.

Installed this several weeks ago in my pixel6 since the OEM battery went all spicy pillow on me. Was easy to install and has held charge great so far. Used a hair dryer in addition to the provided tools, also used my own microdriver set since i like it, provided screwdriver would likely work fine. Make sure you have a magnet or small cup handy during install so you do not loose the screws. Kit comes with a replacement seal - I did not catch this right away and just reused the factory seal.

Value: I would not say it’s worth it. Battery quality: 6/10. I’ve had it for less than a week. Unfortunately, my original battery (70% capacity) lasted long than this battery. Ease of installation: if you’re brand new at this it might be somewhat difficult. Just be careful taking phone apart, watch as many videos as possible and you should be fine. Tool kit: works fine for the job. I don’t get on my phone much until getting home from work. As soon as I get home, I’m lucky to have about 30% charge. Once I use my phone, I have less than about 20 minutes before it dies. Works in a pinch but definitely not recommended for long term use. I will be returning it once I receive a better replacement.

This Luuzkla 8200 battery works well in my Nitendo Switch HDH001 unit with one exception. Due to this battery being an 8200mAh larger capacity than the original 3400mAh battery, the Nitendo Switch battery screen percentage info will not work.
