Galaxy S9 Battery for Samsung Galaxy S9 SM-G960 G960U/U1/A/R4/W/F/T/P/V Replacement, EB-BG960ABE EB-BG960ABA Battery w/Back Cover Adhesive+Battery Adhesive+Repair Tools+Installation Instruction

So far, so good. With light usage and a full charge my Samsung Galaxy S9 lasts for days.The kit includes all the tools and the battery, plus some replacement seals for the case back and under the battery. Replacing a smart phone battery is not easy! These days everything is glued together, and buried beneath lots of teensy screws. Connectors are microscopic. The instructions with the kit are awful; best to find a good video showing how to do it.Give yourself lots of time. If you have a toaster oven, before and after the battery replacement pop the phone in there at about 155F for a while to soften the glue. Use lots of alcohol to removed gummy glue residue after taking the back off. The provided replacement seals work, but they are excruciatingly hard to align and apply correctly. Your phone will not have the same waterproofing when you're done, but at least the battery will work.

Battery replacement. Worked great! It's a bit of a struggle to replace these things. Note, all 15 screws have to be in place for it to work. Follow the instructions, and you'll be fine. I was replacing a Samsung battery that had swollen, so... the backing was already off the hinges.Hint about the flex cables, you just have to press them on, not slot them in like an ordinary power cable, or USB cable.Line them up, square them off. and push until it clicks.Nice thing was, after taking it apart and putting it back together, it actually worked better than factory. Like, the fingerprint sensor was kinda iffy. After redoing things, it was just, instant. Also, with this replacement/improvement, the sound volume and quality increased dramatically. So, just gotta mind your p's and q's with this. Keep all the screws either in the box, or whatever small container where they can be kept track of. Miss one, battery won't charge. At least, in my case, and it states it in the instructions, so, not just me.

Battery has a sticker all over to cover the Samsung logo. Phone dismantle is easy but risky to damage any connection so I didn't take the chance to install the use battery. Got a new one and installed

Don't buy this product! The good news: The toolkit and adhesive are adequate for the job. The bad news: The battery I received was labeled ASDAWN, but was an old Samsung battery, almost certainly removed from a decommissioned phone.My "ASDAWN" replacement lasted about 2 months before the battery capacity dipped below 75% (assessed by AccuBattery). After replacing the S9 battery again, I carefully pealed up the label on the ASDAWN battery and scratched away some of the label adhesive. What did I find? The ASDAWN battery is a re-labeled SAMSUNG battery manufactured on Mar 1, 2018. The "new" battery was, in fact, over 3 years old and exactly 11 days OLDER than my old battery (see photos with ASDAWN on the left with label pealed up and my original battery on the right.).Lithium ion batteries degrade over time. Much of the degradation is caused by charge-discharge cycles, but the maximum capacity of a lithium ion battery degrades with time simply sitting on a shelf. It only took the equivalent of about 50 charge-discharge cycles for this battery to degrade in capacity to my original battery.The product information is misleading, as it claims ASDAWN is the manufacturer. They aren't. In my case, it was an old Samsung battery that ASDAWN had wrapped a label over. It probably will be for you, too.

As noted by others, installation isn't exactly easy, but that's not the battery vendor's fault. All went well with the tools supplied. So far after a month of use the battery life seems as good as the original. The battery came with an odd assortment of accessory bits but didn't include adhesive for the battery into the phone chassis. Not a real problem- even an advantage for the next time the battery needs replacing. No thanks to Apple for starting the non-user-replaceable battery idiocy. Lets hope that the European Union forces an end to this design decision. <rant over>
