Today is my first full day with the watch. I took it off the charger at noon and put it on. Glanced at it not even a minute later and it had dropped to 98% It is now 1802 (so 5.25 hours later) and I'm at 51%. VERY light usage. I have the brightness at the lowest setting. I also had an issue with the watch disconnecting from my phone when I got in my car and it connected to my Bluetooth. After I got out of the car I couldn't get it to reconnect. Restarted phone, restarted watch, nothing. Ended up having to doing a full reset to repair watch. I attached a photo of what I was seeing in my Bluetooth settings menu. Should I be taking this thing back? Edited to add: I've also seen a pretty significant drop in battery life on my phone (iPhone 6).
