Whats a WiFi charger and how it works

The race in wireless charging technology is heating up with Xiaomi who today introduced a new solution, 80W which promises wireless charging of a 4,000 mAh battery in 19 minutes.

Xiaomi says you can charge 50% in 8 minutes and 10% in just 1 minute. Xiaomi’s previous record for wireless charging was 50W with the Mi 10 Ultra.

Also a recent report says that 100W wireless charging technology may be ready in 2021. Given that Xiaomi has reached 80%, the 100W charging target should not be impossible for next year.

However Xiaomi has not given a deadline as to when the technology will appear on the phones but most likely with a Mi flagship next year.

Finally there are many questions raised about the degradation that a fast charge can cause to the battery. One of the companies that has invested in this direction, Oppo, has stated that 125W charging reduces the capacity of the battery to 80% only after 800 charging cycles.

Technology, also known as magnetic induction, is a relatively new feature of charging the famous iPhones or Android phones. Most people do not use it, but here are the benefits it has.

Aside from getting bigger, smartphones are also getting bigger glass. The bodies of many smartphones today are made of glass.

The trend has not come as a conspiracy to break the phone as soon as possible to buy a new one. In fact, glass allows energy to pass through the phone so that it can be charged wirelessly. The technology relies on magnetic induction, which involves the use of electric current to generate a magnetic field, creating voltage, which powers the phone without having to connect to a wire.

Many people are excited about wireless charging. A study by SurveyMonkey found that wireless charging was the most anticipated feature on last year’s iPhones. But in another study, it is said that only 29% have used this type of charging.

This may be because wireless charging is not actually wireless. Need additional equipment to use this feature with companies like Samsung, Mohpie and Anker. Although you do not need to insert a cord into the phone, these accessories need to be plugged into an electrical outlet.

Users also have to make a compromise: wireless charging is less efficient at transferring power than a wire, and thus is slower at recharging the battery. (Mophie says that generally, when both types of chargers were at the same voltage, wireless is 15% slower.)

So why do we need it?

Charlie Quong, vice president at Mophie, says placing wireless chargers in places where people spend a lot of time – such as bedrooms, cars and offices – can allow them to use the phone more without having to charge it long. all the time.

“These products allow people to ‘charge’ during the day without having to ‘park’ their phone,” says Mr. Quong. “They are very, very affordable.”
