is wireless charging as fast as wired charging?
Wireless charging has been with us for years, in everything from electric toothbrushes to the Nokia Lumia 820 from 2012. The big one, as far as wireless charging goes the one supported by most phones and the new iPhones is Qi (pronounced “chee”) charging. Qi is developed by the Wireless Power Consortium and its 247 members include the likes of Apple, Google, Samsung and just about every other big name in electronics manufacturing. The latest phones from Apple, Samsung and LG all have Qi built in.
How wireless charging works: Wireless (or inductive) charging are electromagnetic fields, used to transfer energy from one place (a charging mat) to another (your phone) through the magic of electromagnetic induction.
Apple is making wireless charging cool again with the iPhone 8, 8 Plus, and X. But there are things you should know about this technology like how fast it’s going to charge your phone. The speed of how quickly your phone will charge wireless depends on several variables like which wireless charger you’re using, which phone you’re charging, and what you’re comparing it to in terms of charging speed? When it comes to wireless charging, the general rule used to be yes, it’s slower than wired charging. But as time has gone on and the tech has evolved, that’s not as true anymore. Just like wired charging, there is a faster version of wireless charging. So, just so we’re clear out of the gate, here’s what we have to deal with:
Wired Charging: Traditional charging, found on every phone since the dawn of time.
Fast/Quick/Turbo (Wired) Charging: Newer technology that has emerged as the standard, just with different variations of the name. As suggested, this is much faster than regular wired charging.
Wireless Charging: The wireless form of standard charging, only slower.
Fast Wireless Charging: The rapid equivalent of wireless charging. Not available on all phones.
lt depends, If you’re comparing an older phone with standard wired charging to a modern phone with fast wireless charging, the occurring will probably be faster or comparable at the very least.
But if you’re comparing quick wired charging to any form of wireless charging, you’re definitely getting a slower there. Quick wired charging is undoubtedly the fastest way to juice your phone assuming it supports it. (The iPhone 8 and X support fast wired charging, but it requires a special Lightning to USB-C cable and USB-C charger. They also support Fast Wireless Charging as long as you’ve updated to iOS 11.2.)
And that’s what really throws a wrench into this already not-so-simple answer: not all phones support all standards. So, it depends even more. To make matters even more worse, you not only have to take into consideration what phone you’re using, but also what charger you’re using. Because even if you have fast wireless charging on the phone, you also need a fast-wireless charger before it will work (just like you need a quick charger for quick wired charging to work). And that also brings about another thing worth mentioning: fast wireless charging is louder than regular wireless charging, because it gets hotter, so these chargers have fans in them. It’s more of a light “whir,” but still. It bothers some people. Some phones will allow you to disable fast wireless charging, however.
Going back to the original question we were looking to answer here, there isn’t a straight forward solution it’s going to depend on your phone and charger combination more than anything. Always use wired charging when you need to juice up as quickly as possible, because you can’t go wrong with that. Overnight charging, wireless charging is the way to go to people who love using their phones in bed, then just roll over and drop it on a charger without having to fumble around with the cable. Some people might try to use both ways at the same time, Don’t. It won’t work anyway, not going to charge twice as fast.
Here’s a list of phones supporting Qi technology as of September, 2017
