I’ve seen some reports of bad battery life over email as well, and I suspect that some cases are still due to the battery contact problem I wrote a blog post about here:
Chad your description sounds like you may be affected. Can you try putting a piece of tape over the side tabs of the battery contacts if you replace again?
On-off switch: I’m considering this, but this would be on an entirely new product, not just an update to the Mooshimeter.
Ville’s theory about battery life drain due to bluetooth activity around:
The meter is doing BLE advertisement and anybody can connect to it. But it shouldn’t affect battery life unless some other device is connecting to it.
Sorry I haven’t made a pass through the forums in 2 weeks… working on a new feature. Best
