[6000mAh] Galaxy S21 Ultra Battery, EB-BG998ABY Battery with Repair Kit

Worked great. I was able to power up the phone after replacing the battery. I was not able to charge it, but had enough power to transfer my data.

I used this kit to repair a swollen battery on an S22 Ultra. Perfect battery fit, quality tools, and despite the complicated procedures to actually replace the battery, this kit was able to revive a $1000 phone that was otherwise headed to the landfill. For a 20-something dollar investment in the kit, it paid off handsomely! Replacing batteries in these phones is not for the faint of heart, as you do risk the possibility of puncturing the battery (the one you're removing), and so you should make sure that is discharged as much as possible before doing the switch. Expect about an hour to 90 minutes to do this yourself.

This battery is trash. It cleans 5800 milliamps. More like 2000 milliamps LOL. It's so bad I purchased another one and had the other one installed and got rid of this one. The battery doesn't even last half a day. There are other aftermarket brands out there that are way better and as close as you're going to get to the original Samsung battery. Don't waste your money with this.

Battery Works good, NOT an easy install but that is on Samsung for holding the phone together with double stick tape inside that needs to be pried part to remove the back of the case and then pried the battery off the phone. The phone was only keeping charge for about half day. Now after installing the new battery is has been running on the same charge for over a week. I'm impressed with the battery and would have done it sooner if I knew how bad my old battery was getting. the Screwdrivers they give you are so-so mystery material they worked for a 1 time install but I would throw them out after they are not quality but you can't argue for the price point they worked ok and you're buying a battery not some junk tools. The prying tool that looks like a guitar pick worked well, the screwdriver only had to take 3x screws out and while tightening up the 2nd last screw the driver was rounding over not the screw. 2x hardest parts were learning how to pop the front face bezel off, which required a lot more force to jamb the tool in than I expected for electronics, and the prying the case back off the phone battery was huge amount of force which felt like the phone was going to snap in half pulling it, I heated it up with a heat gun too per the instructions and it still didn't want to let go easy.

Was exactly what it said it would be and fit my s23 ultra nicely, my only complaint is one of the tools that came with it that you needed for the teeny tiny screws stripped after the second screw and stopped working, luckily we have precision screw drivers but it would have been very unfortunate if we didn't have those.

Just installed the new battery and it is working great so far. It was charged at 30% so I'm charging it now to full capacity, then I'll reset the battery settings *#9900#

Certainly did not hold a charge for what would be expected of a 5800 mAh battery, even after calibrating it thru several cycles, it still only lasted half a day...much shorter that the old original battery's current longevity. Returning it, and replaced with the 5600 mAh battery, which is lasting just a bit longer than the 3 year old 4855 mAh original unit. Would've been nice to also have included the back glass adhesive in the kit too.

Un kit de facil.uso para el cambio de la batería. Lo puede hacer uno mismo

Hasta ahora todo bien, dura muchooo más la batería, excelente calidad

Excelente batería, se mejoró la autonomía

No duró ni el mes.

El producto no me funciono, reemplace una bateria de 4000 mah usada por 5 años que ya se descargaba rapido y con la nueva de 6000 mah no hay diferencia. Como si no hubiera hecho nada. me arriesgue y perdií
