No more cords: Wireless charging explained
More and more things are going wireless
A lot of things have gone wireless over the past few years. From internet connections to gaming with your friends, the world is becoming more accessible without the need for physical wires. Over the course of 2018, another aspect of our lives has gone this route: charging one’s device.
Perhaps you’ve already heard of wireless charging and its presence in today’s smartphones, particularly the latest Apple devices. You may have even owned something that could wirelessly charge devices. But, what is wireless charging all about?
Let’s break down the technicalities
Wireless charging is a highly technical concept in the world of electronics. Basically, the way it works is that your charging pad contains coils that give off electromagnetic fields. These fields carry energy with them, which can be converted into electricity to power up the compatible device when placed on the pad.
There are two ways devices can wirelessly charge: inductive charging and resonance charging. Inductive charging is mostly present in low-power charging devices, or ones that require less electricity to power up. This form is limited in range, to the point that the only way your phone charges is if it’s on the pad. Resonance charging, on the other hand, maximizes the range but lessens the amount of charge transferred.
Within the last ten years, several non-profit organizations have created and set wireless charging standards for companies to follow. The most popular of which is the Qi standard established in 2008 by the Wireless Power Consortium (WPC). Other standards include the Power Matters Alliance (PMA) standard in 2012, and Rezence by Alliance for Wireless Power (A4WP) from 2012 to 2015.
All about that Qi
As mentioned earlier, the Qi standard is the most popular wireless charging standard in the world. Most of today’s smartphones and peripherals are supported by Qi. It was established in 2008, with smartphones first adopting it in 2012 through the Nokia Lumia 920.
Qi focuses primarily on energy regulation. Most charging pads that use this standard work with flat surfaces for better energy distribution. Chargers with the Qi standard regulate the amount of charge they give to devices, and immediately go on standby once full. These chargers only activate once a device is placed on top, saving on the cost of electricity in the process.
Most smartphone companies have made the choice to implement the Qi standard in their latest models. Apart from Nokia, companies like LG and Samsung have adopted it beginning with the LG Nexus 4 and Samsung Galaxy S6, respectively. In 2017, Apple accepted the standard with the release of their iPhone 8, iPhone 8 Plus, and iPhone X. The company also planned a charging mat called AirPower that could charge multiple devices all at once, but it has yet to be launched.
Why do most companies prefer Qi, but some don’t?
The goal of the WPC is to put forward one standard for wireless charging in the world. The organization developed the Qi standard in such a way that companies are able to integrate them into their products seamlessly. It’s because of this standard that smartphones are aligned to wireless charging pads through magnets for better charging capacity.
Apart from that, the Qi standard allows for more intelligent control over charging your phone. It can tell if your phone is fully charged and will stop sending electricity to avoid overdoing it. Of course, you’ll be able to maximize the charging capacity of your Qi wireless charger if you’re only charging one device at a time.
However, some companies recognize that most people own several smart devices. This is where other organizations like Power Matters Alliance come in. PMA initially used inductive charging as their base for wireless charging, which is what Qi uses, as well. Now, that same organization was able to look into resonance charging, which removes the limitation Qi has.
That’s one of the reasons why Samsung, for example, incorporated both Qi and PMA standards into their Samsung Galaxy S6. With resonance charging, devices can be charged a few centimeters away from the pad. This is especially good for people who use their phones while charging. While WPC is looking to incorporate resonance charging into Qi, certain factors and compatibility issues with devices make the standard less effective.
What does the future hold for wireless charging?
With all the talk about standards and devices, there’s no denying that wireless charging is here to stay. There are talks between the WPC and PMA on possibly coming up with just one true standard for all companies to follow. The best part is that it doesn’t stop there.
Both organizations are looking to expand their technologies beyond smartphones and consumer devices. WPC has already done so with furniture retailers like IKEA to apply wireless charging peripherals to office tables and couches. Meanwhile, PMA is looking to introduce wireless charging to restaurants and establishments, like McDonald’s and Starbucks with wireless-charging tables. It even reached a point wherein tech startups are developing their own hardware for wireless charging from longer distances.
It’s safe to say that the future is definitely bright for wireless charging. Whether companies will start making it a must-have feature for all their products remains to be seen.

Everyone’s angry at PlayStation’s new no-disc policy, and this is why
It’s a tragedy for nostalgia, ownership, and preservation.
Check in with your gamer friends today. Today, a lot of gamers are up in arms over Sony’s decision to kill the physical game disc starting in 2028. But, if you’re a digital-only gamer or just not a gamer yourself, you might not understand the anger. If you want to understand the ire or just want to relate with your gamer friends, here’s a primer for you.
Ending the era of the physical media
Last year, Nintendo launched the Switch 2. Though the console still has a slot for physical cartridges, the Switch 2 also introduced the Virtual Game Card as a way to digitize your library of games.
Of course, the feature wasn’t positioned as a way to eliminate physical cartridges. In fact, Nintendo just wanted to add the flexibility of physical cartridges to the digital world. In the end, the feature strangely coincided with less cartridges. For example, Pokémon Pokopia, one of the most popular games this year, does not come with a cartridge even if you buy a “physical” copy in a brick-and-mortar store. It was a portent of things to come.
Fast forward to today, Sony has made the monumental decision to stop producing physical game discs starting in 2028. The PlayStation’s future is completely digital.
On a similar note, Microsoft is also experimenting with a disc-to-digital feature. Much like the Nintendo Virtual Game Card, the experiment will digitize libraries and attaches the digital copy to the physical game disc. It sounds awfully like a prelude to killing off the game disc.
Why this matters
The physical disc is synonymous with a simpler time. It represents a time when gamers camped out stores to anticipate midnight releases, when gamers can learn more about their games through an in-box manual, and when gamers can show off their fandom through a beautifully stocked shelf of games.
And yes, that’s part of why this situation sucks, but it’s not the only reason.
If you’re an outsider looking in, this nostalgia factor is the easiest to see. Then again, it’s also the most difficult to relate with, especially if you’ve never had the history of buying physical games.
The more crucial reason — and the one that most people will relate with — is media ownership. By not having a physical copy, you will no longer have ownership of what you bought digitally.
And it’s not an imaginary issue. In 2024, Steam amended its policies to reflect that players do not own the games they buy. Rather, they simply own a license to play the game.
In the same year, Ubisoft delisted The Crew, a sure sign that the new policy means business. Though Steam itself has a relatively good track record of prioritizing its customers, publishers and developers can get rid of games if they choose to.
That limitation doesn’t exist with a physical copy. As long as you have a working disc drive, you can install a game whenever you want, even if the publisher decides to pull it from stores.
Therein lies how much this is a touchy topic. Should you own digital goods in the same way as you own physical ones? If the answer is yes, then selling only the license for the good doesn’t make sense. But if it’s a no, we shouldn’t pay full price for something we don’t own anyway.
Will PlayStation actually delete games?
Now, just because they can, does it mean that they will?
Right now, it’s hard to say. You can certainly go by the optimistic hope that PlayStation would never do something as anti-consumer as that. And yes, there are times when you’d be right.
Plus, there is a good chance that governments, especially those in the European Union, will protect consumers if PlayStation even thinks about deleting a game that others have paid for. Governments have been known to intervene in the past, such as when the EU forced Apple to adopt USB-C as a standard. There are checks and balances available.
Then again, Sony has had recent history of deleting media from a user’s library.
Only a few days ago, PlayStation made headlines for deleting over 500 titles from their library. Starting September 1, users can no longer access movies distributed by Studio Canal, due to licensing agreements. Sony was unapologetic about unceremoniously deleting this content. No refunds, no apologies; just 500 movies, which you thought you bought, gone for good.
No matter how you angle it, Sony’s recent decisions just don’t bode well for media ownership.
You can argue that this is the price we’re paying for not buying enough physical games. Still, losing PlayStation discs, even as an option, is tragic for nostalgia, ownership, and preservation.
The world we live in
Unfortunately, this all comes with precedent. Unless you buy physical games and movies, we already don’t own anything in today’s world.
Outside games, Netflix and Disney+ remove the ownership of movies and shows from us. It’s already common practice for these platforms to remove titles regularly. Some platforms even give you a last chance to catch these titles before they go away. Moreover, they can even restrict access, like with Disney+, if you travel abroad.
In exchange for convenience, subscription services and digital storefronts have made it all too comfortable to not own media. With a rental service like Netflix, that’s all expected, but we’re now at the inevitable stage when even bought games and movies are at the behest of our corporate overlords.
This is where the fury comes from. Companies are getting more brazen about taking more options from us. Between this and the increasing prices of RAM, it’s getting harder and harder to live as a tech-savvy citizen in today’s age.
