The best way to extend the life of your smartphone. And this kit includes the necessary tools to do it yourself.

Replaced a swollen battery on a 3yr Pixel 6, it's been only 2 days but I do see the difference from the old to new battery on use time So far is great, if a get 3 more years, then it's perfect Take your time while assembling and it will be easy

Disappointed with Performance – Did Not Hold Charge and not working. I purchased the Luuzkla 11500mAh (2024 New Upgrade) battery for my iPhone 14 Pro Max, hoping for improved battery life and reliable performance. Unfortunately, the product did not meet expectations. Despite being marketed as a "super capacity" battery with 0 cycle count and full tool kits, it failed to hold a charge from the very beginning. Installation was straightforward thanks to the included tools, but the battery performance was extremely poor. After a full charge, the battery drained quickly even faster than my original battery. I followed all recommended steps, but the issue persisted. This is especially disappointing given the advertised 11500mAh capacity and "upgrade" claims. I've since reinstalled my old battery, which performs better than this new one. I appreciate the idea of a cost-effective replacement with an extended service life, but unfortunately, this product did not deliver. I hope the manufacturer addresses these quality control issues for future buyers.

La compré porque el celular de mi hijo le hacía falta un iPhone 11 Pro Max y le ha funcionado de lo mejor.

Install the battery haven't had it in the phone more than 11 days. And it quit working had it pulled apart and the ribbons broken that connects the battery to the phone. Update as of 21 Jan 2026 .. I got a replacement battery. Had it installed. And the phone seems to be working okay. I will let you know if it decides to die again in a couple days

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.

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.
