What’s the point of wireless charging?

The number of Smartphone users has grown from 2.1 billion in 2016 to around 2.5 billion in 2019. Scary? That includes you and me.

Batteries only have a certain number of charge cycles. This means they can be fully charged and discharged only limited number of times. Once a phone battery’s charge cycles are spent, metrics such as screen time, unnecessary apps , talk time etc begins to count noticeably and the user begins to notice their phone isn’t lasting as long as it used to. But unlike smartphone batteries, certain Dead batteries can be Reconditioned.

And how do you charge the smartphone? The same old wire and electricity isn’t it? Not anymore curious buddy.

For all you curious souls out there, who is tired of charging the usual way, the tech world offers you “Wireless charging.”

When people talk about wireless charging, they often talk Chinese. Yeah, QI. It is pronounced “chee”.

 So What is Qi?

Is it that magic kung fu thing that Po derivers from his paws in KUNGFU PANDA 3 or is it something else? Let’s check out..

TCM ( Traditional Chinese Medicine ) says, Qi embraces all forms of energy, from the most material aspects of energy (such as the trees, your computer, and hair and blood) to the most immaterial aspects (sound, feelings, heat, nerve impulses,mind , and emotion).

But what is qi of the wireless charging world?

The free encyclopedia  says,

Qi was developed by the Wireless Power Consortium.[2]

Qi is a standard that is available to the public and has various RIGHTS TO USE associated with it. It defines wireless power transfer using inductive charging over distances up to 4 cm (1.6 inches).

For those who didn’t understand the technical terms , I would like to put it out simply for you, imagine your mother cooking your favorite food. For example, she is making your favorite beef curry. The aroma is sizzling. The aroma flows to you and you get all energized up. This is inductive charging

Now in the case of wireless mobile charging, our receiver device is a Smartphone. Now that is wireless charging in a nutshell.

In a wireless power transmission system, the transmitter device ( the beef curry) driven by electric power (your mother) from a power source (gas) generates a time-varying electromagnetic field which transmits power (the aroma)  across space to a receiver device (you) which extracts power from the field and supplies it to an electrical load.

Mobile device manufacturers that are working with the  wireless charging include Apple, Asus, Google, HTC, Huawei, LG, Motorola, Nokia, Samsung, Blackberry, Xiaomi  and Sony. 

Check out the most promising Smartphones that use wireless charging..

  • Apple iPhone: 8, 8 Plus, X
  • Samsung Galaxy: S9, S9+, Note 5, Note 8, S8, S8+, S7, S7 Active S7 Edge, S6, S6 Edge
  • Motorola: Droid Maxx, Droid Mini, Droid Turbo, Droid
  • LG: V30, G6 (US version only), G4 (optional), G3 (optional)
  • Microsoft Lumia: 1520, 1020, 930, 929, 928, 920
  • Asus Padfone S
  • Google Nexus: 4, 5, 6, 7
  • BlackBerry: Priv, Z30
  • Turbo 2, Moto X Force

Not bad huh?

But do people really care about the technology?

If we have to keep the phone on the charging pad to charge wirelessly then what is the difference in just plugging it? If the phone could be charged even when I remove it from the charging pad, I would be happy but otherwise its utility is questionable.  While the phone has no wires charging it, the charging pad still has to be plugged using wires and thus not being “wireless” actually, unless you work at a desk but get up a lot.

I think the ability to charge just by dropping the phone on a table is just nice. Also using it in a car/other hands free environment it makes a big difference. Honestly I don’t see much practical application to it in the present, it surely does have huge scope for the future. Nicola Tesla said the same thing 110 years ago.

 Wireless charging may one day replace plugs and wires, similar to how  Wi-Fi had revolutionized our life.

The next question is “ Is it efficient?”

A transformer is formed between a coil in the charger and a coil on your phone. The best transformers of the world have some minimal loss, but the wireless charger is a pretty bad transformer because good transformers posses a metal core and very tight coupling between the coils. A Smartphone and its wireless charger cannot couple beyond a particular limit, and the alignment between the two will never be perfect.

Thus when “wireless” becomes part of the equation ,efficiency drops  by 10-15%. If the phone and charger are not properly aligned the efficiency will worsen. Thus, millions of  Apple iPhone: 8, 8 Plus, X out there use 15% more power than a normal phone would consume. Just imagine how much extra power has to be produced by our electric power houses. Thus, wireless charging has an effect on nature too.

Wireless charging looks promising in the future but what is it promising?

Well, I think if it can charge up cars and bikes using charging pads hidden under parking spaces would be great. In case of mobile phones ,it will only be fruitful if the phone can be charged when it is at least 10 ft away from the charging pad otherwise why don’t we just use long wires? Curious?

When it comes to wireless charging, all the Google searches are in a frenzy around a particular cheesy product>>

Cons


It is a bit slow charger as it is a 5W charger. Please aim for a higher W charger if you are not the SLOW type. It takes almost  double the time to charge a S9 Plus with this charger. But higher W charger costs much more, so if you are looking mostly for convenience rather than fast charging speeds,  the Boost UP QI is your best option.

Go for this if you are ok with slow charging and can’t wait to have yours hands on wireless charging. It’s a good charger at an  OKAY price.

  1. For me I like ‘wireless’ charging on my phone as the constant pushing a cable in and pulling it out can eventually wear down the connections and obviously easy to break a cable if you are not careful with it. Just my thoughts 😀
