For some, wireless charging is a must-have feature in their smartphone. Others couldn't care less about it, preferring faster wired charging for quick power-ups. I tend to fall somewhere in between — it's a convenience I typically use for charging my phone at night or while working at my desk. Regardless of where your opinion of wireless charging falls between the two camps, the feature hasn't changed much since it was first introduced in the Nokia 920 in 2012.
