Introduction

Does your watch battery last less than a day with minimal use, or does the watch only power on when connected to the charger? Replacing the battery may fix these problems.

Flip the watch over so that the face is down. Using a Y#0 screwdriver, unscrew the four 3.5 millimeter tri-head screws.

I have the Gear S2 3G version R730V and purchased a battery thinking these instructions would work, but once I opened the watch it is not the same as the one above. Does anyone have instructions on how to replace the batter on the R730V??

Irene - Reply

Irene I just replaced the battery on my wife’s S2 3g from Verizon. Differences from above are. There is only 1 Philips 3.6 millimeter screw holding the mother board. There are also 5 cables that need to be disconnected. The mother board completely disconnects from the watch. There is no battery casing. Just remove the battery cable, the cable is the one with the little hole on one side and then use a spudger to lift the battery out which seems to have a sticky side to it holding it in. Then reverse order to put everything back together.

I have the watch in the 3G version - R370V . I purchased a battery for it thinking these instructions would work, but once I got it open I see it’s different. I can’t find the instructions anywhere. Can anybody here help?

Russ Brewer, Thank you. I finally got it apart and find that I was sent the wrong battery! Not what I wanted to find, but thanks for your help!

What battery do you replace for the s2 gear class smv 730v

Monica - Reply

Have people been finding that replacing the battery really does help? My watch has been sitting in a drawer for the last year because the battery didn’t last more than a few hours, but everything I found online at the time pointed toward it being a software issue after an update. A battery problem - that sounds like something I know how to handle!
