Galaxy Note 9 Battery Replacement, EB-BN965ABU Battery for samsung Galaxy Note 9 SM-N960 N960U/U1/A/T/P/V/R4/W/F with Repair Tool Kit+Back Cover Adhesive+Battery Adhesive+Installation Instruction

Didn't want to replace my phone right away..found this aftermarket battery to replace the swollen battery on my Note 9. It works but don't feel confident that this would last long..feels like it drains faster than OEM. Anyway as long as this battery last me another year then it's all worth it before I upgrade my phone. - Update (2/4/2022) - So far this battery replacement has held up for 8 months now...haven't really noticed it slow down. Drains about the same as the original 4000 Mah Samsung battery. Like, I said in my previous review if this battery last me a year then it's all worth it since I will probably be going to get a new phone anyway. I will recycle my Note 9 when this battery dies. Will buy another one of this battery and donate it to people who need it the most. To those people who left bad reviews because they could not install them correctly without breaking the back glass. Well, maybe you should not be repairing your phone anyway. Take it to a professional to get the battery replaced. Stop whining about the back glass part that you broke when this is about 'a battery' review. Update (July 12, 2022) **** After 1 year, the battery is still holding charge. It can last between 5-8 hours depending on the usage of the phone. Good estimation of the battery health is probably around 80-85% of it's original capacity. I did not expect it to perform or last this long. I will be using the Note until Sept 2022 and get my new iPhone..yes..I'm leaving the Note. It's been a good 4 year run with the phone and was happy to be able to extend the life of it because of this battery.

Swap was easy, I used a YouTube video for instructions and it went fantastically easy. I can't say as to battery life but will update as I find out. I am glad I bought this kit with all the accessories. Old battery fattened up and blew the back off, so opening it was not an issue. The replacement adhesive worked great and went on easy. The little screwdriver worked great especially after I rubbed on a magnet to magnetize it so installing the screws were a snap.

The Battery: You can't review the battery life after 1 day, accurately, because the problem with cheap batteries is more frequently the lifespan. They start out fine but after 6 months they have a noticeable decrease in capacity. That said, after about 16h, I charged my battery fully, let it drain until the phone died, by leaving a game open overnight, and I'm recharging now. Whereas before I could play that game for about an hour and go from 100 to 60 percent, and it would just drop faster from there, this lasted closer to 11 hours. Tips about the tools: The suction cup is pretty small, but eventually worked. I used a hot air soldering station, not a hair dryer. Try positioning it in the middle as close to the right edge as you can and see if you get a gap at all. The middle of the bottom is another option people recommend, but mine absolutely would not move at all. In theory, alcohol should help dissolve the glue slightly, but in my tests using a needle syringe to precisely deploy tiny drops, it didn't seem to help any noticeable amount, but keep it as a last resort, just don't get crazy with it. The opener (like a thick guitar pick) is great and worked well, however you really need a few more. Actual guitar picks would likely work just to hold the back from re-sealing as you work around the edges. For the top, near the camera, I had to VERY carefully use some additional plastic pry tools that were wedged. I could hear the adhesive slowly pulling apart, so I'd wait for that to stop before continuing. Check out iFixit for better pictures of where the adhesive is - there's a lot and it's strong. If I'd not had another set of phone tools with additional plastic tools, it would have taken me far longer. Metal tools are just asking to damage or short something, even though MOST contacts are covered. I also found that an old credit/membership card worked great to keep the bottom from re-attaching. I just carefully slid it up from the bottom - BE CAREFUL OF THE NFC AND WI-FI ANTENNAE. If you feel any resistance, stop and look under. My card caught them and would have damaged them if I'd persisted without repositioning on top of that piece. Have patience. And absolutely do not use metal tools to disconnect or pry the battery out. If you puncture the pack, you may quickly find yourself with a fireball. Keeping a fire-resistant container (like a glass baking dish) nearby, that you could quickly toss the phone into and take it outside is always good when working with lithium cells, as is a chemical fire extinguisher. You likely won't need either, but if you do, you'd certainly regret not having them more than not needing them. I also recommend charging the first few times in that fire-resistant container or a safe place, like a concrete garage floor, away from anything, just to make sure there are no immediate defects that could cause a fire. I did not need to use either glue strip, my phone held together, and going in a case helps bind it until it's really solid again from heating up due to use/charging. Don't forget to test BEFORE you glue the back on, but after you've carefully reconnected the fingerprint reader, in case you forgot a step or something isn't aligned correctly.

Significant battery improvement. I was having issues of random shut downs and high battery use warnings from apps I wasn't using. I replaced the battery and all is well. I got 4.5 years from the OEM. I'm hoping for a few more from this battery. My only warning is my own fault, not the seller's. The back is glass and more fragile then you would think. Take your time when pulling the back off. They do sell new backs but, I don't need it. It's always in an OtterBox and mounted to the dash of a semi truck.

I first purchased this to replace a swollen battery on Sept 3 2021. It worked quite fine as a replacement..... Well this week, (8/24/2023) it swollen up as well, so I replaced it again. It seems the more you use the fast wireless charging, the worse it got. I would leave it off and on the charger at night. In the morning.., turn it on, and use it for the day. It was until this week, I noticed that the power button on the phone would not work. SO I removed the case, and sure enough, the case had swollen up enough to pop the back cover off of my Galaxy note 9. The first time it did this was the original battery..., I bought this phone used.., and have had it over several years. I am proud that both times it did this, the rear cover was NOT broken when it separated from the phone. Now My Issues with this kit.... 1) The battery tape/glue .... there is NO way I know of to get it to stick to the battery in the kit without screwing it up.., so Plan on buying a separate one to replace the one you screwed up on..... 2) Battery...., I an pretty sure these are very cheap made batteries. I can't complain. I got 2 years of use out of the first one I ever did. But Fast charging .., they do not likey at all...not for longevity that is... 3) the rear case glue/adhesive..., better plan on buying some extras on it as well.......If the adhesive comes loose during the install.., get prepared to remove the deal and start over...., the same goes for the battery glue as well..... All in all.., I'd give it a 6 out of 10 stars for the kit they include with the battery..., The battery gets 3-5 stars..., the glue kits, they get 2 stars.... The instructions get 0 stars...,(not even close to my Galaxy note 9) (I used the ifixit.com tutorial to get close and more correct....) ..The shipping was fast... 9 out of 10 stars..... Lastly.., no where in the instructions does it state the fact that you GOT TO make your phone relearn the battery......When you get the battery installed.., make sure phone works..., turn OFF fast charging...., then slow charge the phone...., THEN run an app on the phone till it dies...(This will take anywhere from 1-2 days depending on the app and the charge...).., You must make sure the phone is dead and won't turn back on anymore...., then Finally, you slow charge it back to full 100%.....This will take about a day to do.... Then the battery should last you for a long while after doing this.... ( I didn't do this the first time.., hence the only a 2 year life span...)

I would have only taken away 1 star for all the little things, but the big one cost 3 more. It's not all bad, like I said it should be a 4 star review with some warnings. Value for money will depend on how well this battery works. Considering I was at the point where 100-25% was fine, 20-5% was 90 seconds, and 5% meant "I'm going to shut off now," the bar is pretty low. Update: I have not worried about my battery after the first 10 charges. It suggests 5 full time from dead to 100%, I did 3 perfectly and then got tired of the angst so just charged around 5%. It's a good battery. Def not an "upgrade" if your phone is new though. Update done: Give yourself 2 hours to get this done properly (I am including research and watching videos). From the top: I don't have a "man-station" with heat guns or hot plates. I built my own PC and had a good ph000 screwdriver. Based off the reviews - I felt if that was the worst part of the kit, then the rest of the people sounded unqualified anyway. But the hair dryer was clearly not enough to loosen the glue. I heated it for as long as I could stomach considering the inner components. They said 1-2 minutes for a hot gun or hot plate at 110 degrees. I went with maybe 8 or 9 with a hair dryer on high. I got no separation so I heated for 5 more. At that point I could get the separator tool under the cover and start to scrape. I already didn't like this kit at that point, but I stuck with it. How hot is too hot? Was I really that far off? Is it easy to heat the components too much if the glue isn't quite ready yet? Info we could have been given. Sure enough, right around the top of the case I got a catastrophic crunch. What do you do then? Stop? Since it was already cracked it just got worse, and then spread down to the bottom of the phone by the time I was done. (PICTURE 1) There's 9 screws up top, not 8 like it says in the instructions. I was VERY close to breaking my motherboard cover and ruining my phone forever since it wont charge if all the screws aren't in and I imagine with solid pressure. The motherboard cover is also stuck the edge of the battery housing (PICTURE 2). This kit really comes with everything you need, even a sim card remover just in case you don't feel like getting up and going through boxes in the basement. That said, it's less than 20 bucks, so when the tab designed to remove the plastic off of the glue for the battery tears off like wet toilet paper... (PICTURE 3) I might opt for a 30 dollar kit that was that much better made - FYI. Again, mine was already trashed, but it didn't help that you have to scrape all of the old glue off the case now (per the instructions) after it has all cooled. Especially galaxies with the curved glass edges. SPLINTERS. everywhere. Yes, I was impatient, so this was my fault and would have been reflected in a 4 star review, but how hard would it have been to make instruction 9 number 3? Right after a set of warnings for what you're about to do. HEY, WHILE IT'S STILL MELTED < YOU SHOULD SCRAPE ALL THAT GLUE OFF THE BACK SINCE IT JUST LOST ALL OF ITS STRUCTURE. The worst part, Why I'm giving this review 1 star, is the instructions. Number SEVEN! I double checked.. Instruction number SEVEN warns you about extra glue around the fingerprint sensor at the top of your phone. After SIX that tells you to put the screws back on to the motherboard AFTER you installed your new battery. I don't know how this could be overlooked. On top of truly not giving you enough warning for what's going on. If you go and look, the replacement glue is THIN layer around the edge of the case, once you get inside the case, THERE'S WAAAYYY more around the camera and down the sides. 1 star for a 5 star kit. I mean come on - I hate the McDonalds Hot Coffee lady as much as the next guy, but could you not be a little bit more clear on where the glue is... what you should be careful to avoid when you're scraping a metal file around the back of your phone... warn us that if your phone is old there is a high chance your old battery will disintegrate on its way out, "but don't worry, you'd rather destroy the bad battery than scrape the housing"? It just says nothing. I understand this practice is somewhat frowned upon, but so should trickling out 1/10th of an upgrade every year and locking our battery inside our phones. Why so shy as the third party?

Exactly what I need. Works perfect and easy instructions too! 10/10 recommend. The battery took charge immediately. You will need to follow instructions on properly cycling the battery through a few charge cycles

My battery was swelling and pushing my back off the phone so I ordered this kit. Let me say now, go ahead and order a replacement glass back now if you don't like cracks. You need the blower to heat the glue! But still a pain to get the back off. And I cracked it. NOT the seller's fault, mine. But as I keep my phone in a case no one will ever see it, right? After watching a couple of videos online I knew what I was going to do. All components in the kit worked flawlessly, battery fit is excellent. The tools are great! The screwdriver is even magnetized to help pick up the very small screws so I stuck it in my desk drawer when done. It took me about an hour to do everything.
