What it is: Wireless charging eliminates the need to plug a device in to charge it again.
Apple keeps cutting the cord. First they made mice without cords and then keyboards and trackpads without cords. Now they’re planning to cut the cord on iPhones and iPads as well.
The main idea behind wireless charging is that you plug a device into a power supply and it can recharge nearby devices within a fixed distance. That way as long as you’re within range of the charging device, your smartphone and tablet will never run out of power and you won’t have to be tethered to a power cord. Just walk through any airport and you’ll find plenty of people huddled around electrical outlets, desperately trying to recharge their smartphones and tablets before their flight takes off.
With wireless charging, public places like airports could place a charging device in the terminal and people’s smartphones and tablets could recharge automatically. Put a wireless recharging device in your car and you can recharge multiple devices as you drive. Put a wireless charger in your home or office and you’ll never have to worry about losing power again (unless the electricity goes out).
Right now, wireless charging is still a dream but it’s coming and it’s going to the iPhone and iPad soon. You could still use the power cord to connect your iPhone or iPad to your computer, but eventually you’ll be able to share files and backup your devices wirelessly as well. Wires get in the way and limit your movement. Just compare the difference between today’s smartphones and yesterday’s landline telephones with cords that stretched a limited distance.
Going back to landline telephones would be as painful as staying with power cords today. Wireless charging is coming next year or the following year, but it’s going to become commonplace soon. Apple is reportedly working with a company called Energous Corporation, but you’ll likely see wireless charging arriving on other smartphones and tablets, and soon laptop computers as well.
Power is always at a premium, but wireless charging will make recharging less of a hassle so you’ll never be without a charge again.
