Here's mine with normal use and auto brightness. Included some Wazing, email, Netflix, iMessage games, etc. I just wanted to kill the battery to do a recalibration and reset network settings. I'm on 10.1 beta 2. Normally, I plug my phone in during the day like when driving in my car. Pretty good battery life so far.
It's a 256gb Sprint model (1661) using a T-Mobile SIM card. Not sure if the Intel modem would have even better battery life.
