Smart-Facial Recognition

For those who are into taking selfies and preserving moments wherever they go, this feature is the ultimate win! This built-in feature enables the camera to identify if there are more than two people in the lens, so that it automatically switches to a group selfie mode,. Facial recognition makes group selfies effortless without the user having to adjust the camera.

More commonly known as HDR, it is another feature that adds more dynamic range and depth to photographs. Smartphones with an HDR camera make even dark photos look lighter in exposure. Ordinary camera phones can only capture so much highlight and shadow detail - with HDR the highlight and shadow details are both increased, making the picture as close to the image seen by a human eye as possible!

Top pick with this feature: Google's new Pixel phone comes with an HDR camera.

High energy density battery

A high energy density battery with 3500 mAh capacity is capable of giving your phone longer endurance, up to at least 18 hours. With a powerful battery like this, you can increase talk time and even run a lot more applications without worrying about fast battery drainage, Also, no need to hold onto a power bank or any other source of power supply!

Finger print reader

No longer a feature limited to Apple smartphones, a finger print reader is advanced to the point where even a slight touch of the user is enough to unlock the device. The latest finger print reading technology in smartphones is equipped with a hydrophobic membrane, which even detects prints even when the users' fingers are wet.

Top pick with this feature: While a number of models are now being launched with this feature including the Oppo F3, OnePlus 3 and iPhone 7 are quite popular for their smart finger print recognition technology.

Dual selfie camera
