Wireless charging and TWS


In the growing trend of modern audio systems, True wireless earphones (TWS) have emerged as a successful category of wireless devices as it provides us with the true freedom of not being tied down by wires. It not only provides the user with a hassle-free interface of being connected via Bluetooth, but also enhances the quality of experience by extending the True wireless experience to wireless charging.

TWS Bluetooth Earphones differ from its counterparts as it refrains from using any wires at all and utilises the concept of TWS+ for inter-connection within the earphones. Wireless earphones give users the flexibility and freedom to work more efficiently while travelling, running, jogging or to enjoy unlimited sports making the longest range movements possible while working out without getting tangled in the wires. The wireless charging battery case allows the device to be completely charged to about 5-6 cycles of usage generally and each cycle provides about 5 hours of playtime.

Nowadays, along with long battery life and enhanced sound quality, some brands are offering additional features to find the lost earphone with inbuilt tracking devices in them taking away the fears surrounding losing one of the earphones like Tile Tracking in Skullcandy.

What is True Wireless?

“Wireless” earphones refer to a device that doesn’t need access to the phone. Wireless earphones fall into three categories such as wireless earphones connected via a neckband, wireless on-ear headphones, and wireless over-ear headphones.

  • But in the case of “Wireless” earphones earpieces are connected to each other with a cable in some way may it be over the head or around the neck.
  • Instead “True wireless” earphones lack a cable or connector between earpieces.
  • Some true wireless technologies also offer wireless charging via electrical induction after being placed on charging platforms like Indy Fuel & Push Ultra from Skullcandy.

What is Qi (“chee”) Wireless Charging?

Qi charging is an inductive charging standard accepted and followed by the majority of the manufacturers. Compatible devices can be charged using induction charging using the electromagnetic property of the current flowing in a coil, without using any cables.

Wireless charging depends on electromagnetic induction between two copper coils, which greatly limits the distance between a device and a charging pad.

TWS designers integrated the cradle for tiny earphones which solved the problem of limited playtime of the earbuds. The cradle is a small handy case or compartment which includes a bigger battery thus it allows the user to charge earbuds without being dependent on a power outlet. Also, cradle makes it easier to handle tiny earbuds and reduces the risk of losing.

Trends and Universal standards in Qi charging

  • It transfers inductive electrical power over the distance up to 4cm.
  • The technology was introduced in December 2008 by WPC (wireless power consumption).
  • Its low power specification published in 2009 and in 2011 its specification extended to medium power.
  • Thus, the overtime specification of Wireless charging has improved a lot.

Wireless Charging Benefits

  • Less Dependence on Cords – Now you don’t need to carry around your USB-C charger wherever you go, Just a cable connected to the charging mat is enough.
  • Compatibility – out of all new innovations many are going to be obsolete pretty soon and one standard will emerge victoriously, but in case of Qi charging, it is already the universal standard and hence there is no ambiguity on its future.
  • No connectors – So, getting rid of all the connectors improves the life of the device and there is no risk of electrical faults.
  • No wear and tear – The same reasoning of no electrical faults is applicable in this scenario too. Since we aren’t connecting and removing the charger from the device the wear and tear of loose connections and wire breaks can be avoided.
  • No overheated battery: As the wireless charger shuts off after full charge there is negligible risk of battery overheat.

 Wireless Charging Downsides

Positives of anything always comes with some negatives like

  • Charging Performance – Wireless Charging Efficiency is 85% as compared to wired nowadays and it’s not clear if it takes into account the features of fast charging or not. The Charging efficiency started at 60% but improved over time hence there is some hope of better efficiency in future
  • Not Full Freedom – Wireless Charging and TWS provides much more freedom as compared to wired counterparts but still its not completely wireless as the charging pad needs to be plugged.


True wireless is a technology that ensures you are not tangled in the wires while enjoying the activities that you love. By pairing of true wireless with wireless charging a lot of benefits like longer life and safe charging can be achieved. So, the next time you are considering buying a wireless charging Bluetooth device, remember you are going to add a lot more freedom in your life.
