Why Are Wireless Chargers Slower Than Wired Chargers?

Smartphone manufacturers have already come up with an amazing idea that aims to change the way we charge our devices: Making wireless chargers. However, wireless chargers are said to be so slow, according to reviews from both tech insiders and users. Once you've intended to buy a new smartphone along with a wireless charger, here’s what you should learn if you don't want to regret buying an unexpected device.

How A Wireless Charger Works 

Wireless chargers typically use magnetic resonance and induction to send electric power to the phone. In other words, a wireless charger will extract electricity from a power outlet and create a magnetic field. An inbuilt system inside the phone then kicks off the availability of an electrical current to charge its battery.

Wireless Chargers Could Fry Your Phone If They Charge Faster

Now, it’s time to find out why wireless chargers couldn’t be faster. In fact, they are capable of doing a really, really quick charge instead of wiping a lot of time. Unfortunately, today’s hardware isn’t qualified enough to complete a safe charge at high speeds as it makes the wireless charger generate too much heat. Not only does the excess heat destroy hardware itself but it also leads to battery explosions. According to a study, wireless chargers consume about 30% to 70% of the power they’ve received for nothing.

Put it aside, manufacturers still have to face a reservoir of challenges and limitations if they want to develop wireless chargers in accordance with user needs. Precision is a telling example. Some types of chargers are unable to work whenever the user has a piece of metal such as coins or keys nearby the charging surface.

Technically speaking, the safety measure doesn’t allow intense magnetic fields to heat up such a metal object – so, either algorithms or distance limitations should be developed as soon as possible for better detection.
