I have been happy using my watch for a good while. Settings haven't changed recently in terms of apps installed, usage levels, #syncs in a time period, etc.
However, last night i went to bed (10:30) with 24% knowing that would be enough to get me through until a 6:30am hour long class, until i'm at work at 9 and can do a charge.
I woke at 5 (the cat had a live mouse in the house) at my watch had 3% left. I put it on charge.
Woke properly and and left the house at 6:10am, when the watch was at 100%.
By 10am it was fully drained.
I just popped it on charge, and it got to 20% when i took it off. It's now 10:24 and it's come up with the 10% warning ...
Any ideas? Is there any kind of Garmin program i can run quickly to see what's using up the battery power (like you get on mobile phones)?
9% now ...
