Instant Charging: Charging technologies have made many advances recently, fast charging being one and wireless charging another. So far, we’ve seen quick charging and rapid charging in most flagships, but instant charging is just what it sounds like. An instant charging feature is likely to give you a full charge and is only expected to take a matter of minutes. What normally would take just over an hour to fully charge a phone could now take as little as 5 minutes.

Better Biometrics: We're used to Touch ID and fingerprint sensing, but there's much more to come: Windows Hello lets you log into Windows smartphones using advanced facial recognition (it can even tell the difference between sets of twins) and phones with iris-scanning capabilities are just starting to make their way onto the market too. By next year, scanning your retina to log into your phone might be as commonplace as typing out a PIN.
