I've seen a bunch folks commenting about the GNex battery drain saying something like "what do you expect with such a huge screen?" I've given this some thought and I'm not convinced that's accurate. Let me explain.
It has a 4.65" AMOLED screen which is larger than any phone besides the Galaxy Note. This is a fact. AMOLED has an interesting property in that it only uses power for pixels which are lit. This differs from standard LCD screens where they uniformly use power regardless of what is being displayed. This is important to my point.
On the GNex, the darker the screen is, the less power it's using. Also, the less pixels lit, the less power it's using. Here comes the controversial part.
When you "remove" the screen area taken up by the soft buttons, you are left with 4.33". That's the same as the Droid X. Looking at the button area, you may notice the buttons illuminate very few pixels relative to the area and the pixels which are lit are not at full intensity but are grey. I assert this area of the screen uses very little power. Therefore, relative to the rest of the screen, the button area uses very little power and has little impact on battery life. This makes a comparison with similarly sized phones nearly apples to apples.
Comparing to the Droid X, which I used to get 2 days of battery with, if the screen on the GNex is the main culprit of battery usage, per the built-in stats, then something is wrong if you keep your screen relatively dark.
For example, I keep my screen at a brightness of 33% or less and choose dark backgrounds/themes where possible, yet my battery life is nowhere near that of my Droid X with the main drain identified as the screen.
I suggest that the screen is somehow very inefficient if it is using so much more power than a "same sized" LCD screen such as the Droid X. So I can't just explain away the power drain based on the "huge" screen the Gnex has. Something else is wrong.
I realize LTE gulps battery but unless I'm in a very weak area where the phone struggles to keep an LTE connection, the screen is almost always the biggest drain.
Thoughts?
