2. Wireless charging
The latest smartphones feature wireless charging, eliminating the need for charging cables. While the wireless charging function may sound neat, it still requires you to have a cable plugging into the wall, as users must have a charging pad. Wireless charging also requires the phone to be lying face up on the pad, which doesn't really allow users to effectively use the device while it charges. Further, testing of wireless chargers has found that they may kill overall battery life faster than typical chargers.
