Second full day using this watch and I love it. Have the 3G version from Verizon. I'm a Tmobile user so I can't use the 3G part of it. My wife won the watch at a work conference and she couldn't pick our wireless carrier... they just gave her the Verizon version. Anyway, first full day of using it, my battery was at 10% when I went to bed at night.. started from a full charge. Figured out the mobile data was turned on, wifi was turned on, and NFC was turned on. So I turned all three off. Planning on turning NFC back on when Samsung Pay finally gets ported to the watch though. Today my battery life is much better. 75% right now after 18 hours of being on. I was wondering if there's anything I can do to get this even better? Small note.. I have "Always On" disabled, Power saving mode turned off. And "Wake Up Gesture" enabled. I would like to keep all three options as they are now. Bluetooth must also remain on since that's my only connection to the outside world with my phone.
