Hi
I've seen a few threads regarding dpi. But aside from aesthetics in the way of smaller icons and what not does lower the dpi have any effect on battery life?

And is there any way to change the ppi on the display like we can do on computers with resolutions? I'd like to have 320 ppi because anything beyond that I won't even be able to tell the difference.

It doesn't affect battery life at all. It just changes the sizes of things.

And no, you can't change the ppi, it is a fact of the hardware. And 'changing' the resolution on a computer is like changing the dpi on the phone.

If you lower the dpi the icons get smaller.

What he is saying is that if you lower the resolution (like on a pc for example from 1920x1080 to 1440x900 it will cause the desktop to stretch therefor causing this images to get bigger)

A lower DPI is like increasing the resolution, all of the icons and layouts will get smaller, fitting more on a screen, but doing so will not enable you to fit more icons on the home-screen unless you use a custom launcher where you can change the grid size.
