I purchased a series 1 42mm new two months ago. Since day one I can only get about 12hrs out of it. I reset the watch and my phone with no luck in gaining battery life. The watch is also running bare bones - grayscale. Activity turned off, sounds off, background app refresh off, etc.. Series 1 42mm = V3.2.3. iPhone 7 Plus = V10.3.3 The watch was dead out of the box, I had to charge it. Can I try anything else? Thanks in advance.
