ASDAWN EB-BR730ABE for Samsung Galaxy Gear S2 Battery Replacement, for Gear S2 SM-R730 / Gear S2 Classic SM-R735 / Gear Sport SM-R600 with Repair Tools + Installation Instruction

have no idea what i was doing im sure its not lasting as long as the original battery but thats ok for me since im new to this and the watch was free just need to a battery and works great for what i need

I have two Samsung Gear S2 watches that the batteries had started to fail. At their worst point, they were getting maybe 45 minutes of run time after charging. I put both of them in a desk drawer and went back to wearing regular analog watches for more than two years. I came across the watches and I was just about to toss them. Then I thought - I wonder if there are any replacement batteries for them. Long story short Amazon had them for $16.00 ea. I thought, what do I have to lose? And I love to tinker. As I got in to it, I found this to be super easy. I did both watches in about 30 min. And now they both run like new! Actually, they last much longer than when new. All the tools you need come with the batteries. Like I said: SUPER EASY!

I ordered this battery for my Samsung Gear S2. The watch was fine but wasn't holding a charge all day. I installed this battery and it seemed OK first day. Second day I was working outside and noticed the watch kept rebooting. I put on charger and finally stopped rebooting. Then the next morning the watch was super hot, said in airplane mode, and then it said too hot and shut off. I finally had to put in freezer a while to get it to boot where I tried a factory reset. It came on and after a while it started rebooting over and over again. I finally took watch apart and put in old battery. It works bur I broke a small cable taking apart again. I think it's just for the vibratory. Stay away from this battery!

Update, after 1st charge and use:After letting it charge fully, my watch was able to last about a day and half. That's pretty good. Wore for the full day, slept with it on my wrist for the sleep monitor and it lasted til about 1/2 the next day. That would include my fiddling around the settings and changing watch faces. So I rate this 4 stars. I deducted 1 star for the cheap and potential damage that the included screwdrivers could've done to my watch. BE WARNED: check the screws on your watch before using these micro Phillips screw drivers.My pictures should help you see the pros and cons. I bought this to replace the battery of my Samsung Gear S2 classic, white. In pic #1, the battery matches the OEM battery. The original definitely needed to be replaced, you can see how it puffed up. Good news and the PRIMARY reason of this kit is to replace the original- so, IT FITS, IT TURNS ON AND IT CHARGES. For now, this is just the initial install. In this regard, this kit is as advertised.The bad things about this kit to keep in mind when YOU buy/install. No. 1, the two micro screwdrivers included are NOT correct for removing the casing. It's fine for removing the screws on the PCB (motherboard), but DO NOT use it to remove the casing!!! Look at my pic #3 (close up of the screwdriver tip) and then look at pic #4, (close up of the screw of the Samsung watch)... you WILL strip or damage the screws if you force the use of these screwdrivers! Luckily, I have a micro screwdriver set with various bit types and sizes to tackle these special screws. And lastly, look at pic #2, one of the screwdrivers arrived bent, there is NO thin aluminum pry bar pictured in the sellers listing (which was replaced with a standard blade). The instruction manual is a not the best. I referred to a few YouTube videos for better tutorials. It was somewhat easy, since I'm somewhat of a electronics geek and tinkerer. If you're not such a person, watch a few videos and most importantly, take your time with the small ribbons!I will update this review in a few days, once I get the battery fully charged and put it to use. It arrived at 54% charged.

Easy to install. Watch a YouTube video before install .. At first I didn't think the Screwdriver was the right one. Because it didn't seem like it fit. But worked great. It was just a illusion. They are made to not come all the way out. Once you pry it open you see they are unscrewed. Battery fit like factory. Fully charged I get about 38 to 40 hours before needing a charge.. I recommend this product!

So this battery is 1 yr old as of purchase and it won't charge past 85% now and just gets super hot if left unattended. The trip wing driver that came with this is a joke, order a good one when you order a different battery, if any good batteries exist for this. Who wants to spend 20 bucks every year to replace a battery?

I'm pretty excited about this product. I have an old Samsung S2 that I received as part of a promotion for a new phone several years ago. I occasionally look at the new watch options, but I haven't found the new features as compared to my S2 watch worth paying for an upgrade. Except for the battery, which wouldn't even last a full day. It was getting worse and I was looking at different watch options, when it occurred to me I could probably just replace the battery. Ordered this battery Tuesday, received it Wednesday, and installed it on Thursday.The replacement process was a little difficult, although that was because of the watch and not the product. The screwdriver that was included in the package was the correct "Y" screwdriver for my watch, which I was concerned about based on another reviewer. I was use it to loosen all of the screws, but only 1 of the 4 screws actually came fully out of the watch backing. I could tell they were no longer attached, and after some finagling I was able to get the watch opened up. After that it was pretty straightforward. Overall, took about 30 minutes.I've had it on for a couple of hours now and it's still at 95%. Totally renewed the watch!

Replaced battery with nominal difficulty. Instructions accurate and included images. The images were small, so I used my phone to zoom in. The battery holds good charge, as instructions indicate, allow several cycles for the battery to become most efficient.
