Wireless Charging: Not Worth The Trouble

Several top end cell phones offer wireless charging now, the Samsung Galaxy S6 probably being the most popular.  Surprisingly , iPhone has not yet jumped on that bandwagon, for which I commend them.  You can buy a case that will allow you to charge your iPhone wirelessly, but I say don't bother with any of it.

The notion of wireless charging is an intriguing one.  I would love it if my phone could charge while in my pocket, while I was using it, or even just sitting on a shelf.  But none of that is a reality with current wireless charging.

As currently available, a wireless phone must be placed, back side down, directly onto the charging pad.  It must be touching the pad at all times in order to charge.  The platform is much larger than a typical charger, making it far less convenient to carry around with you.  Charging also takes longer when done through the wireless interface.  Samsung's wireless charger will also cost you $50.  There some cheaper chargers made by third parties, but all are far more expensive than you would pay for a simply USB charger.

So for wireless charging, there seem to be many negatives:
  • I must be very careful how I place my phone on the charging stand.
  • The charger is much larger and inconvenient to carry around with me.
  • The charger is more expensive than a normal charger
  • Charging takes longer
  • I cannot pick up and use the phone while it is charging
On the positive side, well I guess it saves me the 5 seconds it takes me to connect my USB charger.

When wireless charging evolves to the point where one can charge efficiently while carrying around a mobile device, I'll be impressed. The current wireless solution is simply a waste of time and money.
