My battery lasts 8-10 hours, sometimes less. SoT of around 4.5, I have adaptive brightness off and the screen at either the lowest possible, or no more than 10% when under sunlight only when needed.
Screen is still consuming 80% of my battery. In my graphs, the standby time is awesome. There are always almost vertical declines when screen is on.
My use consists of hangouts chat, textra and hub. My wallpaper is all black. Have most apps set to black too.
