Ok, i understand that. for example if i watch a 2 hours movie at 720p.
then same movie at 1440p they will consume same amount of battery.
Yes and No (in your case, only no).

Here's the thing:

-The screen has enough pixels for a 1440p resolution to display 1:1
-All these pixels will be used, regardless of the resolution
-This means that 1080p will RENDER things at 1080p, and then UPSCALE it to 1440p
-Upscaling required power is neglegible

So this works by making your phone render pixels at 1080p, which is 25% less than 1440p. This means a 25% computational power that can lead to higher FPS. After rendering, it upscales to 1440p.
Yes, it will consume SLIGHTLY less battery in two cases:
-in 1440p you're using 100% of the hardware and on 1080p you use less than 100%. Our displays can't go over 60fps (vsync is on), so if a game runs at 40 fps in 1440p and 50 fps on 1080p, it will be using the same thing, but will be rendering faster
-In low consumption scenarios (like UI draws) where the UI will have to render 25% less pixels, which means 25% less power used in the long run.

BUT, what I just said isn't the big power drainer. That alone would probably account for a 1-2% increase at most. What really drains the battery is the screen. 1080p upscaled to 1440p is still the same amount of pixels powered up as 1440p. This means that the battery will be drained at the same speed.

So, yes, using 1080p instead of 1440p will improve your battery, but absolutely not enough for you to notice a difference.

In your case: if you play a 720p movie on whatever screen resolution, it will consume less battery than the same movie on 1440p. This is because you have to decode the movie and render it to the screen. 1440p movies require double the computational power to decode and display. I'm not sure how much the difference is, but it's there.

This isn't even a real fix. That would need to be done at the kernel level. Some guy tried it on his G3, but nearly broke his device. I'm not saying that this doesn't help, but it isn't the fix that most of you are looking for - the same amount of battery life is still consumed.

Have you tried the App called Pixel Battery saver? That works differently... It puts a mesh which blocks out a considerable number if pixels, as for amoleds black=off right? I mean I have used that app but didn't use it long enough to deside if it helps or not...

I tried uninstalling and installing again Swiftkey and, it seems to be a problem with the theme because if I type without looking to keyboard, I can see that under those big letters there is a keyboard working fine.
By the way I'm on lollipop

This is likely the best solution, and the one I recommended a few pages back. It was immediately dismissed with no explanation.

There is not broken nothing, the g3 apss dont work on another resolution than native, the same thing with some apps from moto, for example, moto display

IF you want a mid-tier 1080p phone, there's plenty of budget Chinese crap out there. Don't cripple a QHD 1440p AMOLED display with 1080p.

That's one reason, among many, I won't buy a OnePlus. I've had 1440p OLED since 2014 and I'm not downgrading. And yes I can see a difference.

And by "Chinese crap", I'm talking about no-name brands all cranking out the same generic stuff. For a couple of years everybody and their brother had 5.5" 1080p displays. Whereas QHD 1440p is the differentiator between the pretenders and real premium feature phones.

Now, everyone is going to 6" -- but with a notch (to copy Apple) -- and still keeping 1080p display! Real Android premium phones have had QHD 1440p since 2014, and the Quark (Droid Turbo/Moto Turbo/Moto Maxx) was about the first.

reducing screen resolution have no effect on battery performance , if you want to save battery or double battery life install "pixel filter" from google play this app
basically lets you to turn off pixels on Amoled screen, i have tested my battery performance with this app and i got increased battery life ,would i ever trade droid QHD over some extra battery no , how ever i use this app + Stock battery server when ever the battery is very low.
