So the last two times I've brought my FR745 with me to my girlfriend's place, I've put it in the top pocket of my small backpack, powered off.
Both times, when I've taken it out, it's powered on and drained to almost no battery, after about 2 days in there.
The first time this happened, I did a test to see how long the battery would last with the device on, just sitting on my desk. I didn't see a huge drain, so figured it must have been knocked around and pressing buttons inside the pocket.
This second time it happened, I was careful about keeping the backpack from getting knocked around, but it still happened.
What do you think is causing this drain? Maybe buttons keep getting pressed so the backlight is on a lot? Or is the movement causing the HRM to turn on a lot, or maybe activity tracking triggered?
What do you think is most likely? This hasn't happened with my other FR devices...
