Is there wireless charging on the iPhone XR
Can the battery be damaged?
In theory, yes, because the structure generates additional heat. Thermal effects will shorten the life of the battery. Apple says smartphone software will be able to figure out when to stop charging before it cools down.

AirPower. Apple’s Qi Wireless Charging
It was Yabloko who developed the platform called AirPower. The world first learned about it in 2017, when the company announced a new development as part of a special event.
In terms of design, the new battery does not differ much from the many similar designs on the market. The Apple AirPower Qi Transmitter is an induction mat that charges three Apple devices at the same time. Connect the cable to the charging platform that will connect the AirPower to the mains.
Does iPhone 8 support the new standard?
For the iPhone, there were such transmitters before, but a special case was required. Since the eighth generation, gadgets have been equipped with a special glass panel with the Qi standard. If you’ve wondered before if the iPhone 8 supports wireless charging or not, now you know for sure that the answer is yes.
Features at work
If you have a new iPhone 8, how wireless charging works won’t be an issue. You will learn how to use this transmitter as soon as you read the annotation. Leave the technical details to the programmers and physicists. In short, the charging structure works by transforming electromagnetic waves, which are transferred to the battery in the form of electricity.
Among the advantages is the ability to charge the gadget in public places, such as restaurants or airports. Latest car models are equipped with a separate compartment for a portable battery.
- The device cannot be used while charging. Incoming messages can be checked, but you will have to wait with games or watching videos.
- A thick case may interfere with charging. With an incoming call, the phone will move from its place and the process will be interrupted.
- Qi portable battery won’t replace your Lightning cable.
- The docking station will not allow you to copy files from iPhone to PC.

How does wireless charging for iPhone 8 work and how much does it cost?
Qi wireless charging is the only wireless power transfer solution integrated into smartphones. No special battery housings or covers are required for use. If you are wondering if the iPhone 8 supports wireless charging and how gadgets interact, learn more about the secrets of the developers. A world without wires, the ability to simultaneously charge multiple devices, as well as use counterparts from third-party manufacturers. advantages of the Qi standard.
Qi guarantees that gadgets will work with a charging surface that meets this standard, regardless of the brand. Place the Qi-compatible device on the surface of the transmitter.
Does iPhone 8 support wireless charging
Apple developers have made a breakthrough in technology. Users have the opportunity to charge their smartphone quickly and easily. Which gadget to choose for the iPhone 8, how wireless charging works, what to do if you have difficulties. the main questions will be discussed in this article.
Features of counterparts from third-party brands
If you don’t know which wireless charger is right for iPhone 8, use any device. Since Apple uses open Qi technology in new devices, most of the charging designs will fit the iPhone. Please note that the innovative iPhone 8 transmitter is not just for your phone or smartphone. It can also be used for tablets, cameras and players. Wireless Charger for iPhone X works in a similar way.
How to charge quickly?
The gadget is easier to charge with a native 5-watt charging structure, but you can also use the option without a cable. IPhone 8 Fast Charge lets you charge your battery up to 50% in half an hour using the Apple USB-C to Lightning cable. The gadget will take longer to charge wirelessly.
They cannot be made powerful
Rather, it is technically possible. No one prevents manufacturers from releasing a charger with a power of 100, 200 or 800 watts, like in a microwave oven. Here are just the influence of that very microwave on everything organic, perhaps, you know.
It is difficult to speed up the charging process for several reasons at once:
- no one will give a certificate of conformity to companies producing powerful chargers for the sole reason that they are harmful to human health
- for the release of powerful chargers, they will have to be supplied with weighty transformers, the weight of which reaches 1.5. 3 kg. Can you imagine such an “elegant package” with a new iPhone and a powerful charger? Me not.
- too powerful electromagnetic radiation will “boil the brains” not only of the owner, but also of the smartphone itself
The saddest thing is that even on the official Apple website there is a postscript: during wireless charging, the iPhone may heat up a little. This is at a power of 5 watts. You yourself understand what will happen to the device when using more power.
Why wireless charging doesn’t make sense
The idea of wireless transmission of electricity came to the mind of scientists at the end of the nineteenth century. It is scary to imagine what prospects the new technology opened up for humanity.
125 years have passed since the great discovery of Nikola Tesla, but “things are still there“. Rather, some steps towards the wireless future have already been taken, but at their core they are pitiful and helpless.
The Qi wireless charging standard has appeared in both the iPhone X and the iPhone 8/8 Plus. Samsung has applied a similar one for several years BEFORE. LG, ZTE, Nokia and a handful of Chinese have their own Qi solutions.
But if we ignore the five-minute delight and shouts of “Wow, no wires!”, Put the euphoria “on the shelf” and think about the feasibility of the technology itself in its current form, you begin to understand that Qi is nothing more than an attempt to squeeze an extra pair of electricity out of the consumer. three hundred rubles.
Qi charging is terribly impractical
For being able to charge your iPhone wirelessly, you’re giving yourself new problems. From now on, you need the most horizontal surface possible. And if, while charging, you received a dozen messages or a couple of colleagues persistently called, returning to the charger, you may find that the iPhone moved off the platform without being charged.
Again, this was not invented by me. Apple itself warns of this. And there are a lot of similar user stories.
Oh yes, the charger can be connected to the magnetic mount. Of course you can, but just do not forget that there are several elements in the iPhone that are not too tolerant of permanent magnetization. For example, compass and camera optical stabilization system.
As a result, one day GPS positioning can go crazy, and your favorite mapping service will lead you into the wilderness. But this will happen, of course, not immediately.
They are very slow
The wireless transmission of electric current is based on the concept of electromagnetic induction. If “on the fingers”, then there are two coils of wire, placed at a certain distance from each other. One of them is supplied with a current of a certain magnitude. An electromagnetic field arises between them, and a voltage arises on the second skein. The charge went.
Of course, all of the above has a number of conventions. Power is one of them.
If you turn over modern wireless charging and look at the output voltage and amperage values, you get a power of 5. 10 watts. For the most powerful smartphone chargers, this value reaches 20 watts.
But these are not the same watts that are written on a traditional “wired” power supply. In reality, wireless charging has a significantly lower efficiency.
- Wired charging efficiency is 95. 98%
- Wireless charging efficiency is less than 80%
That is, the difference in charging speed, at best, differs by 20%. In reality, wireless Qi-chargers replenish the battery capacity two or even three times slower.
They have no normal infrastructure
To rejoice in the presence of wireless charging in a smartphone in 2018 is like rejoicing in the NFC module in the iPhone for a resident of Zimbabwe, Costa Rica and other “224 countries of the world”.
It seems that there is a technology, but its application is very controversial.
If you often have to spend time in the waiting room of an airport or train station, spend a day on buses or spend the night in hotels, you know very well that there are no wireless chargers there. And if they come across, then it is extremely rare.
As a result, all convenience again comes down to using a USB cable and finding a free USB port.
They don’t save time
“It’s more convenient and faster without wires,”. seriously?
How much time do you spend connecting your Lightning Lanyard to your iPhone? I think two seconds.
With wireless charging, it takes one second. Okay, using the Qi standard, I save a maximum of 2 seconds on setting up the smartphone for charging, but at the same time I spend tens of minutes due to their low efficiency.
In the long term, they are extremely unprofitable for small businesses.
Let’s say that in the near future, charger manufacturers will revolutionize and release a Qi charger with a capacity of 60 watts without drawbacks.
Let’s say that you are the owner of a cozy cafe and you keep up with technological trends. Taking care of the visitors, you bought a hundred expensive chargers and placed a couple at each table.
Suppose, on the most “fishy” days, about a hundred people sit in a fully filled cafe. Every second person decided to recharge their smartphone. People are delighted, and you dutifully pay for three additional kilowatts of consumed energy.
This is just a visual example that can be scaled to infinity.
