At first, I thought the case was not seated correctly or had worked itself apart. (I have a Supcase Unicorn Beetle Pro.) Upon opening the case, I discovered that the back plate of my phone had separated due to the battery swelling. I had not experienced any issues with charging or battery life, only that something was not right with the case. I got a quote from a phone repair place for @ $65 to do the replacement. Having replaced the battery on my tablet previously, I was ready to pay to avoid the hassle. However, they informed me that the replacement battery was on back order. Considering the phone is my lifeline for everything, I wasn't about to wait. Got on desertcart and searched for replacement options. Found this one with good ratings and could get it right away (for half the cost), so I went for it. The good news - it went much easier than I thought and so far the battery life between charging is excellent. Instructions are pretty easy to understand and follow although you can tell they weren't written by someone who has English as a 1st language. Everything you could possibly need (I didn't use half of the tools) is included in the package. The most important thing turns out to be the adhesive. It is also the hardest thing to deal with. I had a head start because my case was already starting to separate. I used a hair dryer on 'high' on the back of the case for a few minutes to loosen up the existing adhesive and then I was able to carefully pry off the back plate. You need to be VERY careful. I can see why several people have broken the back plate while doing this. The adhesive is crazy sticky and if you don't heat the phone first or aren't careful, you could snap the plate trying to pry it off. Once removed, the next annoying task is to get the rest of the adhesive, which is in random pieces both on the back plate and the back of the phone. You may need to use a swab and some solvent - again carefully - to get this stuff off. Try not to use cotton. You'll get the fuzz stuck everywhere. It is important to get the adhesive off and have a flat surface to start with or the phone won't seal correctly. Note it is possible that if you do a good job you may still get some water resistant capability, but I wouldn't trust it. Once the original seal is gone, your phone is no longer waterproof. Sorry. No way around that. The next pain is the screws holding on the back of the phone and covering the battery. They are TINY. The included screwdriver works perfectly, but you need to be VERY careful again. They are hard to handle and will shoot all over the place if you fumble with them. Exceptionally difficult to find if you lose one because they are so small. Once that is done, the cover comes off easily and the battery itself is easy to replace. They recommend you test the battery first, before you put the phone back together. This is a good idea - BUT - those tiny screws again. You have to put them back in, then test, then take them out again. Careful and tedious, but not hard. The last concern is the adhesive. The part that goes on the battery is a solid block, so that is pretty easy. The one for the edges of the phone is another story. This was probably the HARDEST part for me. The adhesive is very thin and if you are not careful, it can roll up, become stuck to itself or deform. This makes it VERY hard to get a nice flat, even surface that is spaced on the back of the phone properly. The directions don't provide any hints or tricks for doing this, and it is not easy to tell the best way to peel off what side of the plastic film covering the adhesive. Take your time, look it over and come up with a scheme before you attempt it. I had mine roll and deform a bit, but with the use of one of the blade tools and some tweezers, I was able to get it straightened out. Once applied, carefully press on the back plate and run over it applying pressure with your fingers. I heated mine again and then put rubber bands on it to hold it tight for a couple of hours. It stayed sealed when I took them off and it went back into the case w/o issue. I discharged the phone almost completely once, then recharged it, and then let it run down to maybe 20%, and charged it again. I'm not sure it helps as much as they say, but it can't hurt. I didn't do it exactly as they describe, but it seems to be fine and holds charge very well. The replacement isn't mechanically challenging as long as you follow their directions and have patience. For me, this was definitely worth doing on my own and saving the money. I highly recommend this replacement kit. It has everything you need. It isn't hard. You'll save some money (and your phone). The battery works perfectly. Good luck! Review: Not much available but it seems to work very well. - 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. ## Features - [PLS CONFIRM DEVICE MODEL]-- The repair kit contains the instruction to guide you step by step installation, and we have professional engineers to answer all your questions about the repair process.

The process of getting the old battery out was a major challenge, since it was firmly gripped in place by the factory adhesive. The instructions provided with this new battery were good & helpful. I did end up prying the old battery out from the bottom corner with a screw driver, which shorted it out and destroyed it. Falsely thinking they would work better, I had ordered two other brands prior to this battery. The first one functioned, but would not last most of a day despite the label saying it was only six months old and my cycling it through a full charge cycle several times. The second one had a flakey connector that would not attach to the main circuit board. It also did not come with any instructions (they just expected you to search YouTube for help). I deducted one star for two minor reasons: 1) The battery lead was too long and had to be folded over to align with the motherboard connector, and 2) The battery capacity appears to be less than advertised, although it does last a full day. I do wish this was the first replacement battery that I tried... I guess the third time's the charm. ## Frequently Bought Together - ASDAWN Galaxy Note 20 Ultra Battery Replacement, EB-BN985ABY Battery for Samsung Galaxy Note 20 Ultra 5G SM-N985 N985U/U1/A/T/P/V/R4/W/F with Repair Tool Parts + Installation Instruction - Perzework Rear Cover Back Glass Replacement for Samsung Galaxy Note 20 Ultra 6.9 inches 5G with Reparing Toolkit and Pre-Installed Adhesive (Mystic Bronze) - Eaglewireless Charger Dock Charging Port Flex Cable Connector Replacement for Samsung Galaxy Note 20 Ultra 5G N986 SM-N986U N986U1 N986W N986V+Toolkit (Not for Note 20) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/467675586-galaxy-note-20-ultra-battery-replacement-eb-bn985aby-battery-samsung](https://www.desertcart.com.ar/products/467675586-galaxy-note-20-ultra-battery-replacement-eb-bn985aby-battery-samsung) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-11*
