I have got the latest 2.70 FW, and I would like to share two occasions where the problem seems to be the battery, however I think the device should behave correctly and it is not:
1) I am using it every day for commute. My commute is around 20 mins. When commuting only, I am not charging it every night, since I'm expecting the battery to run for a couple of rides. When I do this I have the following settings on:
-GPS + GLONASS
-No sensors
-Bluetooth on, but not connected to phone.
When the device says the battery is 50%, or whatever that means when the icon shows a "mid" charged battery, I start getting weird behavior, like it turning off when I set it to start a ride. And actually this has also happened with the device fully charged. Also, I have got some missing records.
2) today I went for a 3.5 hours ride. The device was fully charged the night earlier and had the following settings:
-GPS+GLONASS
-Heart Rate, Speed, Cadence sensors
-Bluetooth on, but not connected to phone
When I finished my ride, the device was displaying a "mid" charged battery. I stopped the ride and as soon as I hit the save button it just turned off. When I turned it back on, connected to the mains, garmin connect reported an error trying to synch with the device over bluetooth. I then went into the history section in the device and it looks like it split the whole record into "several"chunks... initially I thought all were valid chunks from the recorded, but the device now reports the following in the stats section:
65535 rides
1193046 hr 28 min
4294967.5 km
As you may imagine I have not ridden that much.
To me this looks like a serious SW error.
Does any one have a suggestion? This is my first garmin product, is it there a more official place where I could report this? is it worth doing?
