The Ideal Smartphone
I'll start with the display. The human eye cannot distinguish individual pixels above 300 Pixels per inch (PPI). A display with a density of anything above 300 PPI is pointless. Period. (The exception being, when Virtual Reality headsets like the Samsung Gear VR and Google Cardboard are used, but I'll get back to that later). Do you really need a phone with 4GB of RAM, a quad HD display, and an octacore processor? Do high end specs make an ideal smartphone? Let's look into each aspect of a smartphone and redefine how it can be "Ideal". Display Based on the screen size PPI can be calculated from this site .

Using a 720p display instead of 1080p means can not only save on processing power (phone runs faster), but you can get more battery life for the day. A super AMOLED or an IPS display can get the job done. That doesn't make much of a differ
