Samsung Galaxy Gear S3 Classic - Watch Battery Replacement 

I've done a bunch of screen and battery replacement on phones and tablets, and this looks so much easier. Just ordered a new battery for my S3, so thanks so much for the tutorial. Looks super easy!

You're video helped get through the battery replacement more than the others out there. Thanks!😊

It seems us S3 community are all having our batteries die lol. Excellent video! I want to upgrade but am waiting for a gen 2 pixel watch. This should get me to whenever that releases!

Great Video. Thanks for sharing. I was able to revive my Samsung S3 Frontier to its brand-new status once again. I had issues before replacing the battery, where it would be fully charged, and not able to last a full day. The day before I replaced the battery, it wouldn't even turn on. After 6 years, I guess the batteries life is complete. If I recharged it every night, that's over 2000 charges. I felt sad to part with the watch since it was still very functional. So glad that a simple battery replacement restored this watch to its original state. I suggest to follow the instruction very carefully. The pieces are extremely delicate, and you will need the right tools for the job. Thanks again for sharing this vide.

Thanks mate, I went from wondering how bad it was going to be, to completely done in minutes. Works great now.

Thanks, great video. Just replaced my battery with no issues. Didn't realise how bad my old battery was. Lasted a couple of hours, then when put on charge shows approx 80% charge left. New battery fitted about 6hrs ago, and charge indicator hardly moved. Thanks again.

I know it's an old watch, but this video, helped me salvage a watch that a recently replaced for my wife. So she has a brand new latest model and I get a refurbished old model (but it's NEW to me and only cost me $15 for a new battery and a bit of frustration opening the case). THANK YOU SIR!!!

Hi great video on battery replacement. I now have the new battery but can you tell me which size/ type screwdrivers to buy please. Many thanks

Thanks for the tutorial. I bought a used S3 Classic off of eBay for $20, got a new battery for < $10, and the battery life is like new. I like these watches because of the MST feature that the new ones don't have.

Good information in an easy to understand format. Inspires confidence that I could do this myself,

Thanks a lot for the great video. Just replaced my battery using it. Worked like a charm 🙂👍

Just finished replacing my battery. Thanks for the guide.

Thank you for taking the time to create and provide this video. I have a similar issue in that the digitizer is faulty on my wii u controller, screen is ok thankfully, will be attempting to replace the digitizer next week now, hopefully its as easy you've shown in your video. :D

your directions were spot on....thank you!

Thank you for the very clear instructions! Much appreciated. 👍

Thank you got mine done in 5 minutes, now on charge, fingers crossed Bill

Thank you so much! Perfect idea to just follow along. Got me a 520mAh Super High Capacity in mine now. Thank you! Cheers from Belgium.

Followed this step by step and it worked perfectly - Thanks!

my daily is working again, thank you so much!

Hey 👋 Just to say, Big thanks for the great Vid for this Samsung S3 watch ! So easy to follow and REALLY helpful 👍 🍻

I'll give it a try see if it works thanks for the info👍🏽 7:17

Just did mine. Great to have new batt. :)

Great video. Unfortunately popped the small flex while trying to break the glue on the battery free. So I think I have to call the watch dead now.

Thanks I appreciate the video very informative and right on the money

Excellent guide! Thanks so much for having something easy to follow along with!

About that flex cable....................so what do I do if it comes loose fro the board. I'm not convinced that it was properly attached BEFORE I began to remove the cover. So, any suggestions on how I can reattach?

Thank you so much for the video!

Thanks a lot, just did it myself 😀😀

I can't see that you have mentioned the best screwdrivers to use. The kit I was supplied with had poorly made screwdrivers. I found the case needed the Tri-point Y00 and the Board needed a Philips PH000. At a pinch, the case screws can get away with size Y0. Please correct me if I'm wrong. The 0.6 x 30mm tri-wing, which was supplied with the battery replacement kit, started to strip the heads rather. These were sourced from AE. If I had replaced from your link I imagine the correct tools would have been sent. Thanks for the video, it was very helpful

Does anyone know if models R765A and R765 use the same battery?? Most i see just say R765, but i have R765A

great job

Thank you!

Worked, thanks =)

Wenn der Akku der Uhr nicht mehr lange durchhält sollte man, bevor man die Uhr aufmacht, zunächst eine andere Prozedur durchführen. Durch eine jahrelange Benutzung und somit das Laden und Entladen, stimmen irgendwann die Kalibrierungsdaten des Akkus in der Uhr nicht mehr. Es gibt keinen Menüpunkt mit dem man die Uhr dazu veranlassen könnte eine neue Kalibrierung zu starten. Es sei man bringt die Uhr dazu die Hardware neu zu starten. Mit dem einachen Ausschalten geht das nicht! Um die Kalibrierung zu starten muss man die "Aus/Ein-Taste" (rechter unterer Drücker) für mindestens 10 Sekunden gedrückt halten, bis auf dem Bildschirm das Wort "Rebooting..." auftaucht. Damit startet die Hardware und Software der Uhr neu. Es wird nichts gelöscht! Aber die Uhr beginnt jetzt mit einem erneuten Kalibrieren. Der Kalibrierungsvorgang beginnt, wenn man die Uhr auf unter (!) 10% entlädt und danach vollständig (!!!) auflädt. Die Uhr ist erst vollständig aufgeladen, wenn in der Ladestation die grüne Lampe aufleuchtet, nicht wenn vorher schon 100% angezeigt werden. Damit ist der Kalibrierungsschritt vollzogen. Man kann diesen Schritt noch ein zweites Mal wiederholen (Entladen unter 10% und danach vollständiges Aufladen). Danach sollte der Akku wieder lange durchhalten. Ist das nicht der Fall, dann würde ich erst den Akku ausbauen und durch neuen ersetzen!

Fortunately the replacement kit only cost me $12. Unfortunately the two side small ribbon connections broke a d my new battery is worthless. Oh well. The watch lasted me 7 years, which is pretty awesome for a piece of tech these days. Cant really complain.

Thanks!

Is this the same repair as on the frontier version of this watch?

Use a heatgun if you have one to loosen the adhesive.

Yeah the battery only lasts a little over a year or so in these. I'm surprised they don't make it easier to replace the battery, also why no rubber seal inside to keep the water resistance, seems like a poor design. I had to replace the battery in a moto 360 back in the day and it had gasket.

hello there! does anybody know if when replacing the motherboard, the entire watch needs to be reprogrammed from an authorised service in order to make the new motherboard as an additional part to work with the other components of the watch and let it function properly? I was told so and I wonder if I can replace motherboard on my own or do I need to have that process done by Samsung inevitably....? thank you in advance!

I broke the ribbon to my motherboard 😮😮. Big mistake. Any suggestions

Gonna try with my wife’s watch thanks

Does this remove the water resistance?

it would be nice if someone can go through the steps and speak them as you disassemble the watch please

Dang, I'm having the problem that seems to be plagueing a lot of people with the gear s3 classic on the forums, where you replace the battery and the power button no longer works despite the screen working and updating battery percentage, and the back button turns on the screen to show the percentage, but the home button doesn't do anything, including turn on the watch.

I broke my cable 😭 such a good video but

Whats the battery size and specs?

No battery in my country kenya,

I'm gonna be one of them people who broke the small ribbon that should have been careful not to break 🤦‍♂️ and fixes for it?

My no longer charges after the replacement: (

Good, simple instructions. However, the annoying background music is completely unnecessary, and annoying. Also, wearing a glove on the hand holding the watch is a good idea to prevent jamming a sharp tool into your flesh, if the tool were to slip off its intended spot.

My Gear S3 keeps going to a black screen, the battery appears to charge, how can you be certain the issue is the battery?

also, you should use a plastic spludger/pry tool between battery and pcb, as you could damage pcb traces or any surface mounted components... (I have been doing laptop and pc repair for a long time, just my observations, not bashing, but hoping for anyone else that may be watching, this may be helpful to avoid possible damage to their watch or other electronic device.)

could you use a hair dryer to heat up/soften the glue (carefully), under the back plate?

Thanks!
