FOBO tire pressure monitoring system report..

The devices will try to communicate (whether successful or not) with any nearby other device that will listen. That effort in trying will put additional strain on the device battery.

The alternative is the device sends out periodic "beacons" of, "Is there anybody, out there?" In this case, the phone application refresh rate would be lower, but in theory the FOBO device battery would last longer.

Would be handy if FOBO shared the implementation background regarding communications so the consumer can adapt and get more use out of the battery.
