Most good midrangers won't run out of space even if you don't use an SD card. These mid-rangers usually pack either 32GB or 64GB of internal memory. The RM1499 Asus ZenFone 3 for instance carries 64GB of storage, comparable to Samsung S7 64GB internal storage as well.
Given our media hoarding habits these days, 64GB should be the comfortable minimum you're looking at.
The hallmark of a good mid-ranger that threatens top-of-the-class flagships would be an equally powerful camera. It's definitely hard to find cameras as powerful as high-end flagships on cheaper devices, but it's possible. Whilst it's hard to rely on specifications to determine camera quality, here's what your camera should hold.
● At least a 12MP rear camera
● Aperture should be f/2.0 or smaller e.g. f/1.7
These are the hallmarks of a decent shooter. However, it’s all very subjective to software optimisation as well and the specifications often do not reveal too much about the camera. If possible, Trying it out at the store will be the best way to judge for yourself.
A stellar example of a mid-range device with a great shooter would be the OnePlus 3, with a 16 MP, f/2.0 rear shooter that’s renowned for its crystal clear shots.
How long your smartphone lasts depends on how efficient your device is, its screen size and of course, the battery capacity. Most Android devices have an average capacity of 3000 mAh so ideally, you should be finding a smartphone with around that battery capacity or higher in a smartphone.
For most purposes, 3000 mAh will last you a full work day from 8am to 6pm with no issues for moderate usage. Unless you're constantly watching YouTube videos, then we're afraid a portable battery pack is your best answer.
