Wireless Charging Is Coming, Which Group Is It Suitable For?

In addition to becoming bigger and bigger, smartphones are becoming increasingly vitrified. From the front to the back of the fuselage, many of the latest smartphones are made of glass.

This trend is not part of the conspiracy theory that manufacturers make mobile phones more vulnerable and prompt users to buy new phones. The reason for the trend of vitrification of mobile phone materials is that electric energy can pass through the glass body and support wireless charging function. The wireless charging of mobile phones relies on electromagnetic induction technology, which uses a current to generate a magnetic field, thereby generating a voltage, which can be charged without inserting the mobile phone into the charger.

Many people are excited about wireless charging. A survey conducted by SurveyMonkey found that wireless charging was the most anticipated feature in the new iPhone last year. In a study conducted by market research firm IHS, only 29% of respondents said they used wireless charging last year.

This may be because wireless charging is not a true wireless technology. Users using wireless charging usually require accessories from companies such as Samsung, Mophie, and Anker. They usually look like discs and stands, and users can put the phone on top for wireless charging. Although the user no longer needs to insert a charging cable into the phone, the wireless charger itself must be plugged into the power source.

There is another problem with the wireless charging function: wireless charging is less efficient at transmitting power than wired charging, so charging the phone is relatively slower. Mophie said that under normal circumstances, the two chargers with the same power, the wireless charging speed is about 15% slower.

So the question is: In this case, what is the significance of wireless charging?

Charlie Quong, vice president of product development at Mophie, said putting wireless chargers in places where people spend a lot of time, such as bedrooms, cars and offices, can make users more comfortable by eliminating the hassle of plugging in charging cables in their phones. Frequently charge their phones.

Charlie Joan said that wireless charging products help people "do not need to intentionally insert a mobile phone, charging the phone around the clock. This feature is really convenient."

As a long-term skeptic of wireless chargers, I am eager to find a useful application for wireless charging technology. Therefore, I will place wireless chargers at the main locations of my daily activities, such as on the bedside, in the car, on the desk, and on the living room table.

In the end, I would consider installing only in the bedroom or carrying a wireless charger in my briefcase.

Charging stand is quite convenient

Charging stands are quite useful. It lifts the phone to a certain angle, turns the phone into an alarm clock, and when you look at the phone screen, the user can know the time, turn off the alarm or see the reminder of the calendar. After turning off the lights at night, it is much more convenient to put the phone on the stand than to charge the charging cable. It doesn't matter if the charging speed is slow, anyway, I am sleeping.

The charging board is relatively less practical. Since the phone is placed flat on the charging pad, you need to remove the phone from the charger if you want to view the message on the phone.

In the office

A wireless charging pad or wireless charging stand can also be placed on the desk so that the user can quickly and conveniently charge the phone when sitting back at the desk.

If the user cares about charging speed and efficiency, the wireless charger is not suitable for use in an office environment.

If the user wants to charge between two rumors, a slower charging speed is inconvenient. In the tests I conducted, the Anker wireless charging dock was about 10 minutes slower to charge the battery to 25% compared to the wired charger.

Another inconvenience of using a wireless charger in an office environment is that the user cannot easily use the mobile phone to edit a message without taking the phone off the wireless charger. With the wired charging method, the user can perform all important operations while charging.

Put in a briefcase

In order to enable users to charge their mobile phones when they are out, Mophie has developed a charging treasure with built-in wireless charging. To charge the phone, the user simply puts the phone on the charging treasure. The convenience of this product is that the charging treasure does not need to be plugged in, which makes it one of the few true wireless charging products.

This product is sometimes quite convenient.

For night appointments, the wireless charging treasure is great. It is wonderful to not have to carry the charging cable when eating with the other half. We put the charging treasure on the table and took turns to charge the phone.

When going out, wireless charging treasure is quite impractical, for example, when taking a bus, because I can't conveniently use the phone to do other work while charging. Fortunately, Mophie Wireless Charging contains a port that plugs into the charging cable.

In the living room

The user can place a charging pad on the TV cabinet or coffee table for the user to charge the phone. This is not only convenient, it shows that the user is hospitable, compared with the use of the charging cable, the wireless charging board does not appear so messy.

Wired charging is better

Unless all friends and family are tech enthusiasts, it is unlikely that their phones will support wireless charging. A more reliable approach is to leave several charging lines. If you want the charging cables to look less messy, you can use magnetic clips to organize them together.

Another disadvantage of using the wireless charging feature in the living room is that the phone cannot be used while charging. In my opinion, it is more convenient to use a longer mobile phone charging cable, I can sit on the sofa and brush Instagram.

In the car

Auto parts manufacturers offer wireless charging brackets that can be installed in air conditioning vents or CD player slots. I tested Mophie's wireless charging stand (mounted in air conditioning vents) with two adjustable arms holding the phone. In order to power the charger, I have to connect it to the car accessories interface via wires.

This is unrealistic

Many cars are integrated with CarPlay or Android Auto, an in-vehicle infotainment system developed by Apple and Google that maps the maps and applications of users' mobile phones to the display of car dashboards. While some cars can be wirelessly connected to CarPlay and Android Auto, many still require cable connections to mobile phones and in-vehicle infotainment systems. The connection can charge the phone at the same time, so who will install a wireless charging stand?

Inductive charging stands may be more useful for older cars that don't support Android Auto or CarPlay. In my car (without car infotainment system), a low-cost charging stand and a USB charger are installed in the CD player slot. I like the wireless charger because the bracket feels stronger and the wired charger charges faster.
