How is the battery life?
With light to moderate usage, you should be able to hit the evening but certainly not a full day phone for heavy users. If you were to turn on the auto-brightness, the battery life goes down by a bit. However if you were to turn on the DARK MODE, it can improve the results. There is no erratic draining observed, but the performance can certainly be improved given the fact that Snapdragon 820 is highly battery efficient and Android M has doze mode and N will bring more efficiency.
One positive we observed is the phone didn’t drain a lot during heavy gaming. A little more than one hour of heavy gaming affected the battery by ~18%, which is good to see.
