Today I came across a classic example of how misinformation is disseminated on the internet.
The title of today’s blog post is taken from an article that was advertised in my facebook feed. It seemed interesting, so I checked it out. The article, posted on gmanetwork.com, claimed that not only was Apple creating a ‘truly wireless’ charging technology, but that it had been reported on Techcrunch that “the wireless charging technology can work over long distances.”
Now here’s the thing: I know a thing or two about physics, and I can assure you that this will never happen. They will never invent a wireless charging technology that will allow consumers to charge their iPhones and iPads over long distances. It’s just never going to be practical. Apple may be good, but they can’t change the laws of physics.
So, okay then, let’s track down how this nonsense got started.
The link they gave as their source was for Techcrunch’s twitter feed, and sure enough it contains a video report titled ‘Apple creating long-range wireless charging tech.’ In the Techcrunch report they stated
“Apple is building technology that would allow iPhone and iPad owners to charge their devices wirelessly without needing to plug them into the wall or even on a charging mat. This is according to a report from Bloomberg which claims this wireless charging technology could work over long distances as well, although how long those distances are was not specified.”
As we can see, Techcrunch is indeed saying wireless charging would occur over “long-range” and “long distances,” citing a Bloomberg report. They provide a link to the report:
Apple Developing Wireless-Charged iPhone for as Soon as 2017
Here’s what the Bloomberg article had to say on the topic:
“Apple is exploring cutting-edge technologies that would allow iPhones and iPads to be powered from further away than the charging mats used with current smartphones…”
That’s it! There is nothing at all about “long-range” or “long distances.” In fact, the Bloomberg report explicitly states “a distance of about 1 meter,” and cites a patent application from Apple for “Wireless power utilization in a local computing environment.” The patent describes a system that could power a mouse and keyboard within roughly a meter of a base. When it comes to the truthiness of the Techcrunch report, we immediately see there are two problems:
- A meter is not “long-range” or “long distance.”
- A mouse and keyboard use far less power than is required to charge an iPhone or iPad.
In other words, the Techcrunch report is nonsense. They grossly misrepresented the report on Bloomberg.
The report on Bloomberg has been widely cited. Many other websites have made the same error. Here are some other headlines:
Report: Apple developing long range wireless charging tech for iOS devices
Bloomberg: Apple developing extended range wireless charging
Apple reportedly developing long range wireless charging technology for 2017 iPhone
Bloomberg: Apple working on wireless charging at-a-distance
That last article ridiculously says:
“Not to be confused with existing wireless charging solutions that depend on contact between a surface of the device and a specialized charging mat, at-a-distance charging means your phone can charge while it is still in your pocket.”
That’s truly comical. It is highly unlikely that they are ever going to wirelessly charge iPhones in your pocket.
The system described in Apple’s patent is one for powering low power devices within a meter or so of a base. Charging an iPhone would need at least 10 times more power. It would need to be closer to the base, and it would need to be correctly oriented. I would also have health concerns. Are we sure it’s completely safe to sit in such a high strength magnetic field? Personally, I would wait until such a device has been in widespread use for years and proven completely safe before I would use one.
There’s also the issue of devices that are sensitive to magnetic fields. A magnetic field strong enough to charge a phone in a person’s pocket could also erase the magnetic strip on their driver’s license and credit cards.
Anyway, this whole story is a great example of how misinformation is spread through today’s media. You start out with a story that says one thing, and then other websites get it wrong. Today’s news sources just aren’t very careful when repeating information.
