I purchased 3 of these devices around 6 months ago. These are v3.2.
Two of these have had the battery run down already.
There was no low battery warning on either.
I have a couple of older pre3.2 sensors that are still running on their original battery.
Anyone else out there using these sensors and having short battery life?
I have mine up and running for about 1 month. Battery level now read at 88%. At this rate, it would probably end up with approximately 30% at the 6 month point. Seems like the battery life is indeed on the short side.
