No More Power Cords for Smartphone Devices

Wireless charging means, as the name suggests, you no longer need to plug a cable into your smartphone to charge it. Simply placing it face up on a special mat or tabletop is enough to start charging up your smartphone’s battery, be it the iPhone X, iPhone 8, Samsung Galaxy S8 or any number of different smartphones that support wireless charging.


Thanks to wireless charging, one advantage that we can all share is that charging your phone through a wireless charger will be much easier compared to traditional wired charging. Enabling wireless charging, you will no longer need to plug and unplug a cable every time you need to charge your phone, simply drop your phone on the charging pad and it starts charging without doing anything else.


Unlike plugging in a device, wireless charging will allow itself to transfer power safely without actually touching any exposed electrical connectors.  In another words, this reduces the chance of a connection failure and electric shocks. According to many experiments, several injuries have resulted from conducting your phone during when it is charging. Shockingly, several many injuries and even death has been linked to improper use of cables or cellphones while charging.  Sounds scary, right? But it happens. Wireless charging can be safer because as soon as you pick it up, the charging automatically stops decreasing the chances of any injuries or deaths compared to regular wired charging.


However, wireless charging itself still continues to host a couple of conflicts that wired charging seems to combat without any struggle. The main struggle for wireless charging can be handed down to its lack of time and efficiency in successfully charging a cell phone. According to a study performed by Juli Clover, the absolute fastest way to charge an iPhone 8, iPhone X, or iPhone 8 Plus is with a USB-C power adapter and an accompanying USB-C to Lightning cable. Charging with USB-C activates a "fast-charge" feature that's designed to charge the iPhone to around 50% in 30 minutes.They also found that as wireless charging takes more time to top up your phone, it will take more power to completely charge your phone too.


Not only can wireless charging decrease battery efficiency compared to regular conventional charging,  wireless charging also makes your phone overheat much more which can harm your battery. There are many discussions around whether or not " wireless charger heat harms your battery" amongst those who have started charging their phones wirelessly. According to How-To-Geek, wireless charging usually generates a bit of waste heat and can even make the phone battery overheat when compared to the conventional cable charging.  Some of that wasted power will be in the form of excess heat and the heat will translate to more wear and tear on the battery.


You might be asking yourself of how wireless charging is actually possible, well the answer comes to inductive charging, whereby power is created by passing an electrical current through two coils to create an electromagnetic field. When the receiving magnetic plate on the mobile device comes into contact with the transmitter - or at least within the specified range - the magnetic field generates an electrical current within the device. This current is then converted into direct current (DC), which in turn charges the built-in battery.


As we linger through 2018, the technology for wireless charging keeps on getting better and better compared to wired charging. By 2019, we might even see most production cars such as Chevrolet and Ford to offer wireless charging as an added option on all of their car models for 2019.
