I've noticed in the last week that my watch isn't fully charged in the morning after being on the charger all night. The first time it happened I decided to pay attention to how I was setting in the cradle. Last night I was careful to make sure it was securely in the cradle and that it had started charging. Now, it may be my Newfoundland coming by and disturbing it in the middle of the night, but it seemed to be in the right place this morning when I took it off, but it hadn't charged fully. I will keep an eye on this and report back.
