Review: Brought New Life Back to My Favorite Phone, No More Battery Throttling, Perfect Replacement! - 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!
Review: Works perfectly for my old Note 20 ultra - 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.desertcart.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.

### ⭐ TERRIBLE! This should be illegal!!
*by M***Y on December 13, 2025*

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.
