iPhone X Review: Wireless Charging
The sixth article is my iPhone X Review focuses on a new feature that is not only on the iPhone X, but also on the iPhone 8 and iPhone 8 Plus; That feature is Wireless Charging.
When you look at all of the new features of the iPhone X, one that might not stand out is wireless charging, given all of the other "shiny" features of the iPhone X. Features like Face ID, the OLED screen, and Animoji. There are those technologies that Apple includes in their devices that when they are initially introduced seem like an "oh, that is nice to have", but it is just a gimmick. When you first look at these type of features, what you do not realize just how fundamental of a shift it can be.
At first glance Wireless Charging may fall into that category, yet I think it will become a primary mechanism and absolute necessity for iPhones going forward. The fact that it is included with the iPhone 8 and iPhone 8 Plus means that Apple is making a huge bet on the technology. Although with Apple putting into their latest iPhones, it will end up trickling down the line and eventually be ubiquitous. As with many other things, but it has not always been the case, when Apple implements a technology it quickly becomes a must have in other devices. I think that Wireless Charging may become that type of technology.
History of Power on iPhone
Unlike many other aspects of the iPhone, the ways that it has been powered have remained largely stable. This is likely because changing the connector cable causes uproar amongst the community. In fact, Apple has only changed the power cable once in the ten year history of the iPhone. That began with the iPhone 5 in 2012. Prior to that, the 30-pin dock connector was used. Although, you could use either Firewire or USB with the original iPhone. Firewire support was dropped with the iPhone 3G, but it still utilized the same cable.
Since 2012, all iPhones that have shipped have utilized the lightning cable as their only mechanism for charging. With the iPhone 8, iPhone 8 Plus, and iPhone X this changes. These iPhones still support the lightning cable, but it is not the only charging method. You can now use wireless charging to charge your iPhone X.
What is Wireless Charging
When people say "wireless charging" two different images can be conjured in ones mind. The first, and least common, is one where power would both figuratively and literally being transferred through the air, similar to how some images of Nikola Tesla's laboratory have been shown. These images have electricity flowing across the entire picture. This is not really what people mean. The second possible image, and one that most users mean, is actually what is actually known as inductive charging. To make it easier on everyone, I will use the two terms, wireless charging and inductive charging, interchangeably.
The concept of inductive charging is not new, not by a long shot. Inductive charging is used in a variety of different products. Some of these include motorized toothbrushes, razors, and even some batteries. It has been in use by phones since 2009 when the Palm Pre was introduced. Manufacturers of Android phones have been including wireless charging for quite a while.
For wireless charging there are actually two competing standards. The first is the Power Matters Alliance (PMA) or as it is more commonly called, the AirFuel Alliance. The second standard is the Wireless Power Consortium standard, Qi, pronounced "chi". Apple has gone with the latter of the two standards for its wireless charging.
The first inductive charging product that Apple released was the Apple Watch. The Apple Watch has never had any other type of charger. The Apple Watch uses a slightly different inductive charging mechanism versus other devices using inductive charging. The difference with the Apple Watch is that it uses magnets to get a secure connection to the charger.
The iPhone X also includes inductive charging. Unlike with the Apple Watch, the iPhone X does not include a wireless charging pad with the iPhone X. The iPhone X, as well as the iPhone 8 and iPhone 8 Plus, uses a wireless charging standard known as Qi, pronounced "chi". However, given the wide variety of existing Qi chargers, you will not need to spend a lot of money to be able to purchase an inductive charger for the iPhone X.
The iPhone X, with iOS 11.0 or 11.1 has a limited charging speed of 5 watts. This is the exact same wattage that comes with the little power brick that has been included with every iPhone sold since 2007. This changes with iOS 11.2, which should be available now. iOS 11.2 increases the maximum output via the wireless charging coil to 7.5 watts. While the actual difference seems small, this is a 50% increase in power.
Right now Apple only advertises two Qi chargers for the iPhone X, and iPhone 8 and iPhone 8 Plus. These are the Mophie Wireless Charging Base and the Belkin Boost Up Wireless Charging Pad. I picked up the Mophie one the same time I purchased my iPhone X.
Mophie Charger
The Mophie Wireless Charger is a 24.7 watt charging pad, well beyond the 7.5 watts allowed by the iPhone X. The Mophie charging pad comes with its own 24.7 watt power brick. The charging pad brick is not USB. Instead it is a standard electronic plug, one that you would find on many other products. The one benefit of this plug, though, is that it is reversible and symmetrical, so you can plug it in either way and it will work. This is very similar to how lightning cables are, which ultimately means that you do not have to do the "USB Dance" like you might with USB A cables.
The physical size of the Mophie charging pad is approximately 3.75 inches in diameter, so it is not a big device. The pad itself is black and has a bit of grip to it thanks to the rubber that encases the entire device. When you place an iPhone on the Mophie pad the gripping rubber minimizes the movement of the iPhone. One downside to some third-party wireless chargers is that if you receive a message and your phone vibrates, it could vibrate off of the charging pad. This does not happen with the iPhone X and the Mophie Wireless Charger.
One of the more common places for a wireless charging base might be in the bedroom. One thing that humans are not good at is sleeping with the light on. Many electronic manufacturers intend to dazzle their customers with a lot of lights, and one of the potential downsides of any charger is the light that it emits. When there are a lot of lights on a charger, they are likely LED and typically very bright. The Mophie charger does not have this problem. There is one single light that is on the bottom of the charging pad and you are not likely to see it unless you are really looking for it. This is a huge plus, particularly if you intend to use a wireless charging where you sleep.
In my own usage, I have to actively look for the light in order to find it, so it should not be too much of a problem. However, if the light is a problem there is a universal fix for it. You can place some black electrical tape over the light. The benefit of this, is that it will match the rest of the Mophie Charger. Even though the Mophie Charger is pretty good, there is still one improvement, or option, I would like to see.
Wishlist
The one thing I would like to see is the power brick and cord be either a lightning or USB-C cable. I completely understand why they went with the propriety power brick and connector, but it would still be nice to have the option for using a USB-C cable to charge. This would need a 29 watt charging brick, but for those of use who already have that, it would not require another charger since we may already have the necessary equipment. There is another wireless charger that I looked at.
