I would like to make a semi-scientific way of judging battery life usage for Lumia 920 owners. I would also like to see if we can pin down some "big-picture" factors that can negatively affect battery life, such as carrier and LTE availability. Please keep any additional notes you add to a minimum, as the thread can be quickly polluted by long-winded personal stories of usage. If you post here, please keep your usage consistent, which means do not change your settings on and off all day. I have included my results since I pulled my phone off the charge this morning, and I will update again at the end of the day after keeping these settings on all day.

To find the approximate % per hour consumption, use the battery info screen. Here's the equation:

% consumed so far / number of hours since last charge.

So when my battery was at 89% remaining on the battery info screen, my equation looked like this:

11% / 3 hours = 3.66% battery life per hour.

As you can see, with my settings, I lost battery at the rate of 6.67% per hour today. Pretty disappointing that I need to charge after 12 hours.

My battery easily lasts a day on heavy usage. I did about 2 hours of heavy usage and it only dropped 10%. It takes about a week to calibrate your battery. Drain it and charge it for a week and you'll be good. Oh and turn of NFC and Nokia Drive from running in the background along with apps you don't use or don't have a live tile.
