Hello, I've been using my Venu 2 for a little over a week now and I've been loving it but just this morning something odd happened. I went to bed last night with the battery at about 50-60% and when I woke up there was a warning screen on my Venu 2 saying the battery was at 10%. I've been wearing my Venu 2 to bed every night since the 23rd of April with with no significant battery drain. I know I have sleep and wake times set as I've noticed raise to turn on stops/starts working at these times (I don't have the screen always on) and I have Pulse OX set to only record during sleep and it hasn't seemed to affected the battery that much. I also don't seem to have activated any kind of activity that would increase sensor usage or anything while sleeping. Is anyone else having this issue. Does anyone know if this is a software issue or is it possible my Venu 2 is defective?
