ASDAWN 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

Everything worked out it's the disassembly that's a difficult part. You really should use over 90% isopropyl alcohol to soften up the glue on everything. I don't think I would have got it apart without using it. Also don't use that metal tool around the battery I punctured my battery during disassembly almost caught it on fire. I basically did a hail Mary soak the battery with 99% alcohol loosened up the adhesive and got it out of there before it caught fire. I will say the battery works perfectly so far. I still haven't went through the three full charge cycles but compared to the battery that was in it it's like a new phone. We'll have to see you long-term if it has some kind of trickery in it where you hit a certain point like 50% or 40% and then basically the battery is flat. But it's acting normal so far. I was to the point where I was constantly having to keep the phone on the charger and just having my phone in the pocket for an hour was losing 20% battery. I just use the adhesives with the kit which works but I don't think they'll be as watertight as the liquid drops but I don't plan on getting it in the water. My phone was already refurbished once so chances are the screen's already been off so it's probably not watertight already. It was either this or buy a new phone so basically for $25 if it worked it was going to be worth it. On a side note I already had a cheaper backup phone cloned in case this went wrong until I could get another one. I consider myself pretty good taking stuff apart and reassembling it was fairly difficult and the harnesses are very small. They all went back everything's working. You should also purchase a different screwdriver the one with a kit is not hardened enough and rounds out the screws I had to drill two screws out. That's kind of a nightmare. Dremeling flat spots trying to use a flat screwdriver on screws. All the factory screws have blue loctite on them so they don't come out that easy. I was basically pushing as hard as I could with that little screwdriver and with a pair of vice grips to turn it to try to keep them from stripping. Also I will bought this kit because it come with written battery instructions removal. I think it left out the part where you have to remove the speaker at the bottom so I almost damaged my phone trying to remove the battery before that point. This is a Note 20 ultra maybe the instructions are more generic. But the speaker at the bottom definitely had to come out to get the cables out of the way and you had a detach more cables at the bottom just one set. The battery seems excellent though so far.

I had a Galaxy S10+ where the old battery swelled up so much, it actually did the hard work for me of removing the back plate from the phone and was thoughtful enough to detach the battery itself from the phone innards. How considerate. So when I got this replacement battery kit, disassembly of the old one was a breeze. I did not use the included screwdriver and used my own, but I suppose it would have worked in a pinch. As it happened, the old battery bit the dust while I was on vacation but I chose to wait 'til I got home to repair. If I wanted though, I could have had this shipped to where I was and used the included tools to replace it (although I don't know how I would have heated up the back plate if needed... maybe a hotel hair dryer?). The hardest part of the whole process was really because I wanted to make sure I removed all of the old adhesive residue. Some careful use of alcohol and cotton swaps took care of most of it but when it came to getting the residue off the back plate, the good old "scrape it with a fingernail" proved to be the best technique. Getting the new battery installed was easy, and once I tested it to make sure it worked as expected, I applied the adhesive to the battery, got that tucked in, and then put the adhesive on the back plate, got that sandwiched onto the phone just right, and I let it sit that way overnight with rubber bands to hold it all tight and give the adhesive the best chance to cure. I know it won't really be as waterproof as factory (or maybe not even that water resistant) but I'm pretty careful about that anyway... I started using phones when water resistance was just a crazy idea and I've always treated my phones as "don't let 'em get wet" beyond a stray raindrop. I suppose if I get worried about it, I'll remove the back plate again and apply the appropriate seal... but who am I kidding, it's a 4 year old phone at this point and if something happens, well, it was fun while it lasted.
