[5800mAh] Galaxy S23 Ultra Battery, 𝗨𝗽𝗴𝗿𝗮𝗱𝗲𝗱 EB-BS918ABY Replacement Battery for S23 Ultra SM-S918U SM-S918U1 SM-S918B with Repair Tool Kits

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.

My old battery was getting weak so I changed it to this battery. Something is wrong with the internal circuits on the battery because the phone won't know what capacity the battery is actually at. Sometimes it will take 5 minutes to charge from 20% to 100% and sometimes it will discharge that quickly as well. Also now when I plug it USB to a computer it will actually discharge instead of charging. It's quite a bit of work to change batteries so don't waste your time buying this junk battery.Edit: vender sent a replacement battery and works exactly as it should for a few months now. I'm not changing the star rating because I still had to disassemble this phone twice. Beware of the quality issues.

The tool for opening is plastic and broke instantly. I ended up using a small screwdriver to open. Other than that worked perfectly.

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.

as another reviewer wrote, the battery is not as powerful as advertised. they placed a sticker over the real information to show a different power rating.but, it does work. however, you need to find an instructional video on youtube in order to use because there are no instructions.would I buy again? I cannot answer that now. will have to wait and see how well the batter performs, but seeing as how I have a charger at home and in my car, the power capacity not being as advertised is not likely to concern me very much.if power capacity concerns you, get several power banks because any battery or phone is likely to run out of power. most people have several chargers at home, in car, and at work, so being away from a power source is not really an issue. this battery and the tools provided are "probably" good enough to fulfill your needs, but you will need to find a youtube video.you may also need a larger flathead screwdriver or metal scraper or something to help with peeling the battery off from the inside of the phone where it is glued. I only used the tools that came with the battery and ripped the old battery foil packaging, but not sure it mattered because the old battery went into the trash.

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.
