Recently, I've noticed my 945 Tri has a battery problem. I don't run long enough for it to be GPS or HR, etc, and I only wear it when I actually run nowadays. What I noticed is that it is draining power when it is OFF. I turn the watch off using the Power Off selection after every run, and then store the watch in my case. I pull the watch out two days later to run again, and find the battery significantly drained. Two days ago, I checked the percentage before powering the watch down... 68%. This morning, I powered the watch up for my run... 50%. The watch has been powered down for two days! What in the world is going on here?
