I hope they get this fixed. I did not have these battery issues with my Venu 2 Plus.
I bought this watch on February 7th, and would return it if that were an option at this point.
I am using the same settings that I used on my Venu 2 which easily got 10 to 12+ days with the exact same settings and usage patterns. On the Venu 2 Plus, I only have stock apps and usually get 3 to 4 days. I was able to use some Connect IQ apps on the Venu 2, but I don't on the Venu 2 Plus for fear of making the battery life even worse.
I have even tried turning off the music and phone options in the phone Bluetooth settings, so I only get notifications, and my health and work out info syncs. No noticable charge on or off.
