Smartphone resolutions and PPI

I'm a bit confused about smartphone resolutions and pixels per inch (PPI).
Like you could get a phone with a worse resolution but better PPI (on a smaller screen) so which looks better for playing movies?

Both are the same.

Better to get higher ppi on bigger screen.

PPI is a measure of pixels over an area. It tells you how pixel-dense the screen is. The higher the number the crisper the image (though much beyond 300 becomes hard for the eye to distinguish at normal viewing distances).

It's a great measure for comparing handsets of different screen sizes as resolution can get confusing. Will a 5" screen at 1080p produce a better image than a 4" screen at 720p? Looking at the PPI gives us the answer.

Size is entirely subjective. For me, my Note 2 is too big, while my iPhone 5 is too small. I'd say 4.5-5" is probably the smartphone sweet spot - a big screen but still pocketable.

Now and again I pick up my old HTC HD2 for quick browsing, and it's still very pleasant.
4.3-in RULE! Well, some of today's 4.5-inchers are smaller than the HD2...

The Note 2 is easier to hold than the Note 1, despite having a bigger display. Display size, as you alluded to, isn't the be all and end all of how usable a device is.

It's massssssivvveeeee!

I held one last week and even with the whole "limited bezel" thing it feels like a flipping laptop screen.

AhmadCentral  Aug. 10, 2013 at 22:07

Oh and i also got a sneak peak at the new Xperia phone coming Oct/Nov this year ;)

Isn't it 6.something inches? That is pretty damn huge, a true Phablet.

Stupid auto correct...

matt101101 / MOD  Aug. 11, 2013 at 00:03

Xenon flash? Optical zoom? Optical image stabilisation? Many megapixels? All of the above?

I'll see to it tomorrow, you'll have the top spot to yourself for a whole day, I don't think we publish on a Sunday (I might be wrong though haha :p).

AhmadCentral  Aug. 11, 2013 at 20:56

Basically its the sony honami I got to see. And the Z Ultra as well.

matt101101 / MOD  Aug. 11, 2013 at 22:19

Balls, I totally forgot about writing that thing. Sorry mate :(.

How did you manage to see that early?

AhmadCentral  Aug. 11, 2013 at 22:45

My work usually gets devices / demos before launch/announcement for testing purposes.

I also got to see the lumia 1020 before that was announced.

AhmadCentral  Aug. 11, 2013 at 22:48

Oh and no worries about the article. Wouldnt have been able to read it on my pc anyway because my PSU failed today :(

Going to have to get another one and try and fix my PC asap

AhmadCentral  Aug. 15, 2013 at 09:58

But they have different models coming.

JanSt / MOD  Aug. 15, 2013 at 11:25

always wondered: do they have good battery life?

AhmadCentral  Aug. 15, 2013 at 11:35

I dunno. Never really used one more than 10 minutes.
