Has anyone gotten any 3.7V batteries to work? There are some cheap ones for RC helicopters that are about 5 for $10. I saw there was another thread about higher capacity replacement. I'm not sure, but the last post mentions having batteries of the same voltage, so I guess that means the 3.7V batteries don't work? I can't find any inexpensive 3.8V batteries that are small enough to fit the gear.
The only battery I've found for the Gear is the same one from the UK linked above (
here it is on the US eBay site). Including shipping, it's $40. Plus you need the right tools -- I only have a set of miniature philips head and flat head screwdrivers, and taking the Gear apart requires some kind of mini torque bit. (FYI, the flat head screws on the front of the Gear are just for show!) The set the guy in this
tear down vid suggests is $30 on Amazon and $20 at Walmart.
So minimum $60 to replace the battery. Concrete examples of cheaper alternatives are welcome. My battery worked fine until a month or so ago, when I noticed it was draining at an extremely high rate -- 8% to 10% an hour. I've done everything I can think of software wise -- different versions of Gear Manager, deleting SAproviders from my phone, and finally finding out there was still a drain when the Gear wasn't even connected, then rooting and deleting some apps, flashing the TizenMod ROM, upgrading to newer FW not yet available for the US, all with no joy.
I can only guess that it's the battery now, but I'd prefer not to spend $60 on a guess.
