Yuriman - I'm guessing the Moto X is counting some sort of active notification, like the time always being on with a black background, as 'screen on', not what most of us consider screen on.

First - you're time off battery = screen on time which would normally be impossible unless you're doing something on your phone 100% of the time. The lack of apps showing up in your battery usage list (wifi being second, Android OS next, Cell standby for goodness sakes) basically shows you're not actually doing anything on your phone - it's in what most of us would consider standby, but b/c of the active notification, it's being considered screen on.

Then, the nearly straight line of battery usage over 15 hours and again where off battery time = screen on time. 'Normal' battery usage is a series of slopes and horizontal lines as the phone is used and then put down. Your WLD screenshot actually shows only about 20 minutes of app usage.

So if I'm reading this right, your battery life isn't actually that impressive - 15 hours off battery with generously 30 minutes of actively using your phone is pretty bad. The Note 3 would easily last 2 days under the same working conditions of barely being used and 6 hours of actively using the phone on calls/apps/etc.


First off, that's not active notifications counting the screen as on. I literally turned off "sleep", left the phone on with autobrightness enabled (showing the homescreen and my widgets), and waited 15 hours for it to die.

You're absolutely right in that it isn't a realistic use case, but what it illustrates is that the screen doesn't actually draw all that much power. It's doing CPU/GPU intensive stuff and being in poor signal areas that kills your battery, not the screen. I can do 10+ hours of web browsing on my phone on a charge, does that count? I can also run a graphically intensive game for 4 hours and run it from 100% to zero in that time. I can also sit in an area of extremely poor signal and have my phone die just sitting in my pocket in 24 hours, not running anything and with the screen off.

This is mostly a thread derailment so I apologize - I think this started when you commented that you get 6-9 hours of screen on time and there was general disbelief as you're not going to get 9 hours of screen on time on the Moto X in any real-life usage. You then provided "evidence" by creating a unrealistic scenario where your phone is sitting unused with generally static content.

So I'm not trying to make a statement about what draws power on smart phones - from your screenshots I thought you were legitimately confused on what most people consider screen-on time (i.e. screen on while actively using your phone) and that you thought your phone was getting extraordinary battery life.

What we all want are phones that last 10 hours of active on-screen use when in mixed connectivity throughout the day - true all day use phones. That day is closer than I would have thought a couple years ago.
