Battery for Samsung Galaxy A51, 5200mAh Upgraded 2024 New 0 Cycle Battery Replacement for A51 SM-A515F SM-A515F/DS,EB-BA515ABY with Professional Replacement Tool Kits (Not for A51 5G EB-BA516AMY)

Works as it should. I didn't have any issues with my phone other than the battery dying too quickly. Was a tad tricky to change out but all tools needed were provided. Just you tubed a video.

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 worked for a day but once it went to zero my phone would not charge at all. Had to revert to my original battery. Original battery is over 2 years old and does not have this problem, can easily go to zero and charge.

So far so good !! Battery lasts much longer. I did the 3 cycle initial charge and will see how it's life turns out.

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.

NOT AS ADVERTISED!!!I bought this battery kit because the battery in my phone couldn't hold a charge for longer than 5 minutes. Granted, this battery has fixed that issue.However, the loss in stars comes from advertising of this battery. The stock battery I had was 3700mAh in capacity. This new battery is advertised at 4600mAh. This new battery has gone through a few cycles of going from 100% - 0%, and my phone still detects the new battery at 3700mAh when it is calibrated to the new battery now. Great battery, false advertising. Would recommend if you have a battery you need fixed urgently.

Samsung has been making battery replacement more and more difficult. Now in addition to having to deal with removing the fragile glass back cover due to the waterproofing you also have to remove parts of the phone. Six really tiny screws as I recall. Lastly the battery is glued in and needs to be carefully pried out. I should mention that the newer phones are fragile internally so care must be taken. This battery replacement kit contained all the tools necessary to do the job. So no hunting around for the right tool or having to make do with a not so right tool.In my case the battery swelled and dislodged the back cover. This made it easier to remove as long as you take your time and don't try to force it. Otherwise you will have to heat your phone and then slowly pry the back cover off. Consider also buying a replacement back cover. This way if you accidently damage the cover or just don't have the patience to pry it off slowly you're covered. Once you have access to the inside of the phone you need to remove like 6 screws. They are in tight and the heads can get easily stripped. This is probably the hardest part so be careful. Finally you should have access to the battery which will need to be pried out - at least that was what I found.I've been replacing batteries on Samsung phones since the S4 which was trivial by comparison. If it wasn't for the $150 price and a 1-2 day waiting for my phone I would have had the battery store replace this battery. If you choose this route you should be clear on what the process is if your phone comes back damaged which is why I have always swapped the battery myself.

If you do this, be sure to have a bucket of sand close by in case you poke the battery to hard and it blows up in your face. I managed to install this battery in my wife's A11, the old battery was badly swollen. The phone went through post and boot up without any problems. So far so good. The only thing I used that was not in the kit was a pare of old guitar picks that were thinner than the case tool provided. So far everything works as advertised. Good kit.
