If you're planning to purchase one of the recently announced iPhones (iPhone 8, iPhone 8 Plus or iPhone X) then you'll find it supports Qi wireless charging out of the box. But if you have an older iPhone - any device with a Lightning port - you can still benefit from the feature. Here's how to add wireless charging to any iPhone.

Before we begin, there seems to be some confusion over what exactly is wireless charging, with various critics calling out Apple for the fact its wireless charger uses a wire. We should point out that the wireless part of this charging scenario is between the phone and the charger only. We're still some way from phones being able to charge via little bits of electricity floating around in the air.

The iPhone 8 uses Qi wireless charging, exactly like the LG G-series, Samsung Galaxy S- and Note-series, and all other smartphones advertising wireless charging. Though it may not be truly wireless, being able to throw down your phone on top of a pad before you hop into bed is much more convenient than fumbling around for cables in the dark.

Qi wireless charging uses inductive charging technology, which involves two coils of copper wire (with a core of iron) - one in the device you are charging (or in a case attached to that device) and one in a pad or mat on which you lie the device. When you put the two coils next to each other an electromagnetic field is created and that allows electricity to be passed between the two coils.

While the two devices need to be touching or within very close proximity, the coils can be sealed within the devices. 

How to get wireless charging on older iPhones

Wireless charging can be enabled on iPhones that don't have the feature as standard by adding a case or other device that integrates an inductive coil and can be inserted into the phone's Lightning port. 

In order to make the magic happen you will also need to purchase a Qi charging pad or mat. This also integrates an inductive coil, and when plugged into a power source and placed in direct contact with your iPhone it is able to charge your device's battery.

If you purchase a larger wireless charging mat you may be able to charge multiple devices at once, and all from the same single power source.

A disadvantage of adding wireless charging in this way is that it prevents you being able to use the Lightning port for other things. If you have an iPhone 7 or 7 Plus, this will be a problem if you want to listen to music via a pair of Lightning headphones.

Typically speaking wireless charging is slower than wired charging, with most Qi wireless chargers offering only 5W. This is the current speed supported by the iPhone, though with iOS 11.2 it will be boosted to 7.5W. Fast wireless chargers that double this output are available, but useful only if the phone (or device you're using to add wireless charging to the phone) also supports this higher speed.

Keep in mind that if you've added wireless charging using a case, you will likely need to remove that case before you can charge it normally, connect it to a computer over Lightning or hook up some Lightning headphones.

Wireless charging can also make it difficult to use your phone while it charges, though you can get round this by selecting a charging pad that also functions as a stand.

What are the different standards of Wireless charging?

There are two major groups in wireless charging arena, which means there are competing wireless charging standards.

The Wireless Power Consortium offers Qi (pronounced Chee), which is the inductive charging technology used by the iPhone 8 and iPhone X.

Meanwhile the AirFuel Alliance, which was formed by a merger between A4WP and PMA, offers both resonant- and inductive technologies.

The AirFuel Alliance is encouraging the use of both technologies within products, but while resonant charging is included in Qi's specification it is not necessarily supported on all devices.

In general, the vast majority of phones that support wireless charging and the products that enable you to add it support Qi. Qi is also what's now used in select Starbucks outlets, for example.

Best products for wirelessly charging the iPhone

While wireless charging may not yet be featured on the iPhone, there are options for Apple fans. Here are a handful of ways that you can enable wireless charging on your iPhone now.

AirCharge

There are some great charging stations in this article, but from our testing, the best around is AirCharge. You simply purchase a clip on case for your phone and a charging pad to connect to your computer or a power outlet.

You can then simply place your iPhone on the pad and it will start charging. It's so easy, and with cases for the iPhone SE, 6, 7 and their Plus models, it's a versatile solution. 

The iPhone 6/6s case costs just £44.99 and the Slimline charger is only £28.99, so it's relatively cheap to set up. You can then invest in more pads for home and office or use your phone on a public pad. McDonalds, Starbucks and Premier Inn are investing in AirCharge and using the free app you can see where there is a pad near you when you're out.

There are 4,600 public locations, so you should be able to track one down easily.

An iPhone 7 and 7 Plus case is to retail soon from £44.99.

Antye Qi Wireless Charger Kit

The Antye Qi Wireless Charger Kit includes a receiver case and a wireless charger pad. The version for the iPhone 7 Plus costs £22.99. The Lightning connection used by the case is easy to unplug, so you can charge or sync your iPhone without removing the case.

You can buy it from Amazon here.

Mophie Charge Force & Juice Pack Air

Combining the best of both worlds is Mophie's Charge Force in tandem with Mophie's Juice Pack battery case. This way you get extra power on the road and an almost effortless recharge when back at base. You need both products to charge wirelessly. See our Best Battery Cases for iPhone 7 for more details.

Compatible with Qi and other wireless charging technologies, you can top up your iPhone 6/6s/Plus or 7/Plus and Juice Pack wireless cases at home or work, or in cafés, cars and anywhere that has a compatible wireless charging pad. Mophie offers Charge Force mounts for your home (the Charging Base costs £34.95/$39.95), plus desk and car (£49.95/$59.95).

Just place your Mophie-cased iPhone on top of the Mophie Charge Force Charging Base. As soon as the internal magnets lock together, power will start flowing to both your phone and battery case. Unless you need to sync or backup your iPhone using cables this allows for a near cable-free existence.

Mophie Wireless Charging Base

The Charge Force technology works with the Mophie Juice Pack Air for iPhone 7, and will work with other wireless-charging enabled smartphones.

For iPhone 7 owners the Charging Base costs $34.95 or US$39.95, while the Juice Pack Air for iPhone 7 (available in Black, Gold, Rose Gold, Blue and Red) costs £89.95 or US$99.95 direct from Mophie UK or Mophie US.

Mophie also has a Juice Pack Wireless battery case for the iPhone 6 and 6s, which features a 1,560mAh battery capacity and universal wireless charging base. The case plus charging base for iPhone 7 cost £89.95 or US$99.95; for iPhone 7 Plus it’s £119.95 or $129.95.

Mophie Juice Pack Air Battery Case with Wireless Charging, (£89.99 for the iPhone 7 version) works with any wireless charging base. It’s available from Amazon here.

Qi Wireless Charging by TORRO

Qi Wireless Charging by TORRO (£18.49) is a case that plugs into your Lightning port and can be used with a charging pad, such as the Portable Power Bank by TORRO (£39.99) which also includes a lithium charged battery capable of three additional charges for your mobile device.

You can also charge two devices at a time using the USB port at the back. You can buy the Wireless Charging case from Amazon here and the Power Bank here.

The leather wallet (for iPhone 6s) pictured costs £34.99 and is available here.

There are a few alternative charging pads available to use with your iPhone once you have fitted it in a charging case.

The WoodPuck is a Qi Wireless Charger Pad that looks like it’s made from wood. It costs £39.99 and is available from Amazon here.

Energizer, the battery manufacturer, also makes a range of charging mats, along with adaptors. For example, the Energizer Qi Double Induction Pad available for £11.29 from Amazon here. Remember, you will need a compatible Qi-enabled case to charge the iPhone.

The Picket Qi Wireless Charging Pad costs £9.99 and is available from Amazon here.

It doesn’t have to be a case. Those looking for wireless charging without having to use a bulky case might want to take a look at one of the following: 

iQi Mobile

iQi Mobile, a 0.5mm thick wireless charging receiver that sits between your existing iPhone case and your iPhone. Because its a receiver rather than a case, it’s compatible with any Lightning-enabled iPhone, from the iPhone 5 to the iPhone 6s Plus.

The receiver features an incredibly thin cable with a lightning connector at the end, which bends around the bottom of your phone and sits permanently in the Lightning jack. The receiver works specifically with the Qi wireless charging format.

The benefit of the iQi Mobile receiver is that you can keep your existing case and add wireless charging to your iPhone (although a soft case is recommended). It costs £21.99 and you can buy it from Amazon here. Note that you are adviced to use it with a soft iPhone case. 

Elefull Charge

The Elefull Charge is a receiver that plugs into the Lightning Port. You an then sit the receiver on any compatible charging pad, or tuck it inside your iPhone case. It costs £10.99. £5.99 from Amazon here.

There are some cases that are compatible with both standards. For example, the Bezalel Latitude.

Bezalel Latitude

Those looking for something a little more ‘complete’ than the likes of iQi Mobile may be interested in the Bezalel Latitude for the iPhone 6/6s. While many wireless charging accessories specify a certain wireless charging standard, like Qi, the Latitude will work with any type of charging system – according to the manufacturer, anyway.

Unlike other options on the market that are fairly bulky and unattractive, the Latitude looks sleeker and more Apple-esque in design – and a price tag to match, setting customers back £44 on Amazon at the time of writing, and that’s without a wireless charging pad. It may be a bit on the slow side though, with a maximum output of 5V/1A – those interested in something faster may want to look at the below option, the FLI Charge.

FLI Charge

One of the biggest downsides to using wireless charging when compared to traditional wired charging is that it generally takes a lot longer to charge your phone, especially those with large capacity batteries like the iPhone 6s Plus. It’s an issue that needs to be overcome before people untether themselves from charging cables, and the FLI Charge system could be the product to do that.

The FLI Charge system doesn't only provide wireless charging capabilities for your iPhone, but also drones, tablets, smart watches, speakers and even GoPros – essentially anything that charges via a USB/MicroUSB connection, via a range of accessories. The FLI Charge system comprises of the FLIway, the charging panel, the FLIcase for smartphones, FLIcube for USB-powered devices and FLIcoin for micro-USB powered devices.

But what makes FLI so different? Instead of using inductive charging technology like the likes of Qi, FLI uses conductive technology which the company claims “charges as fast as plugging into a wall” and can charge up to eight devices simultaneously, a feature not currently possible with inductive charging which offers around ~60 percent efficiency.

What’s better is that due to the innovative design of the system, you don’t have to worry about device orientation, an issue with current solutions. It also constantly detects the surface for unapproved objects (i.e. Apple Watch, water) and will shut the power transfer down and hopefully avoiding any lasting damage to the product or system.

Following a successful IndieGoGo campaign back in 2016, the FLI Charge system is available to buy from the FLI website. The essential kit starts at $149, while those on a budget can opt for the $99 simple setup.  

How to use the wireless charging in Starbucks

The Starbucks cafes that offer wireless charging use AirCharge power points, great if you've invested in an AirCharge case.

There are clever devices attached to the pads though, so even if you don't own a case, you'll be able to charge your iPhone right there at the table.
