Wireless charging dates back to the late 19s when electrical pioneer Nikola Tesla demonstrated magnetic resonance coupling—the ability to transmit electricity through the air by creating a magnetic field between two circuits, a transmitter, and a receiver.

Today, there are about half a dozen wireless charging technologies in use that aim to cut cables for everything from smartphones and laptops to kitchen appliances and cars. in this article, The iPhone Wireless Charger Explained.

Wireless charging is advancing in the healthcare, automotive, and manufacturing industries as it promises greater mobility and advances that could allow small Internet of Things (IoT) devices to operate several feet from a charger. Distance.

The most popular wireless technologies in use now rely on the electromagnetic field between two copper coils, which greatly limits the distance between a device and a charging pad. Apple incorporates this type of charge into the iPhone 8 and iPhone X.

Why wireless charging?

This minimizes wear and tear or potential damage to the Lightning port while recharging your iPhone’s battery without a cable plugged in.

A wireless charging setup generally consists of a circular pad that is wider than the width of your iPhone. Just place your iPhone on the pad and the battery will start to charge. You can charge the Apple Watch wirelessly only via the packaged dock or a compatible third-party solution.

Technically, the power transfer process requires a cable, the power cord that connects the wireless charging pad to an electrical outlet. Power travels through the cord from the outlet to the charging pad.

When your phone begins to charge, the screen lights up with a circular animation with the message “Charging”. A small lightning bolt also appears above the battery icon in the status bar. Meanwhile, the charging pad illuminates a single multi-colored LED or ring as a visual indicator of the current charging status.

iPhones that support wireless charging

iPhone models that support wireless charging have glass backs, which allow their receiving coil to connect to the induction coil of the charging pad.

However, you can install a protective case on your iPhone and still take advantage of wireless charging. Avoid cases that store items with magnetic stripes or RFID chips, such as credit cards, passports, hotel keys, etc., as the recharging process can damage their functionality. Remove these items or use a different protective cover before charging your phone.

Thick cases and covers can also be problematic. If charging does not start on its own, remove the case and try again.

The following iPhones are compatible with wireless charging:

iPhone 11 pro max

iPhone 11 pro

Best Wireless Chargers

elkin Boost Up Wireless Charging Stand

Belkin’s Boost up Wireless Charging Stand is a good option if you prefer to use your iPhone while it is charging. The 10W wireless charger is cleverly designed to charge your phone in portrait or landscape mode. The two LEDs can be seen regardless of the orientation of your phone and can alert you when there are other objects in the holder.

Anker PowerWave Pad and Stand

Anker’s platform and support prove that you won’t have to spend much on wireless charging. Both are made of plastic with a rubberized finish on the bottom to prevent slipping and slipping, though they don’t get too wet. A small LED flashes blue during charging and blinks to indicate that there is a problem.

We like the Stand Over Pad because you can easily view your phone’s notifications, but Anker’s Pad is cheap enough that you can grab a few to spread out in various places around the house. Both come with a 4-foot micro USB cable, but you’ll need to provide your own power adapter. Not a big surprise at this price.

Apple MagSafe charger

The Apple MagSafe charger makes wireless charging a literal add-on, using magnets to connect to the iPhone 12 line. There’s no guesswork in summing things up; It just works.

The MagSafe charger delivers 15W of power to your iPhone 12, iPhone 12 Pro, or iPhone 12 Pro Max, which is twice the speed of most 7.5W chargers. The iPhone 12 Mini, however, is limited to 12W with MagSafe.

Apple’s MagSafe charger is also compatible with AirPods Pro and AirPods with wireless charging case. This is definitely the best wireless charger for Apple fans; Just keep in mind that you’ll need to buy a 20W USB-C power adapter if you don’t already have one ($ 19) for best results.

iWalk Magnetic Wireless Power Bank

When it comes to external batteries, Anker makes a reliable product. But if you’re willing to go for the more generic option, you can save some money by choosing the iWalk Magnetic Wireless Power Bank, which costs around $ 30 or around $ 15 less than Anker’s Magnetic Power Bank.

It is slightly larger and heavier than the iWalk Anchor alternative. It has a 6000 mAh battery (instead of 5000 mAh), but it offers a slightly faster charge (the iWalk claims up to 7.5 W for the iPhone) and the Ring offers some protection when you are holding your phone and watching videos. It also works as a kickstand, which is good.

How to wirelessly charge an old iPhone

iPhone models older than the iPhone 8 and iPhone 11 don’t have the necessary electronics to support wireless charging, so you can’t add a wireless charging pad to an older iPhone and wait for it to charge.

But there are several wireless charging cases you can buy for older iPhones that add wireless charging; Of course, the downside is that your iPhone will only charge wirelessly in the particular case, and these cases add some weight and weight to your iPhone. add support. In bulk.

And these charging cases also handle a Lightning port, so you can’t plug anything else into that port while in the case.

Still, you can appreciate the freedom and convenience of adding wireless charging to an older phone.

Is it wrong to fully charge the smartphone?

With the increasing ease of charging via wireless technology, the question is: is it bad that your mobile device’s battery is fully charged all the time?

Experts said that while you can’t overcharge a smartphone or tablet battery because the electronic components don’t allow it, keeping it fully charged will accelerate its degradation.

When a lithium-ion battery is charged and discharged, the ions move back and forth between a positive electrode (made of lithium cobalt oxide or lithium iron phosphate) and a negative electrode.

As a battery charges, the positive electrode releases lithium ions which move towards the negative electrode and are stored as energy. As the battery discharges, those ions return to the positive electrode to be used as electricity. As the lithium ions move back and forth, the electrolyte that serves as the transport medium is depleted over time.

This is better not only to keep your smartphone below its maximum load but also to prevent the charging and discharging pendulums from swinging violently.

“In general, if you cycle the battery from top to bottom, that’s the worst thing you can do for battery life. If you can cycle the battery between 45% and 55%, then that’s the best you can do.”

Conclusion

Hope you enjoy this article. There are a few things to keep in mind when using a wireless charger. First, your iPhone will not charge wirelessly if it is physically connected to a charger or USB port. You can only load it from one source or another.

Second, your iPhone may feel a little warmer than usual when you charge it wirelessly due to unused energy that is represented as heat.
