Does Qi wireless charging work with a case?
Qi wireless charging ?
The short answer is most of the wireless charging can work well with most phone cases.
Qi standard is a method of inductive charging that works at farther distances than just directly from the transmission point. The Wireless Power Consortium notes that "With inductive charging, the charge passes between a transmitter and receiver coil placed closely together, usually only separated by the outer casing of the two devices (<7mm)." What that means is, a well-made Qi standard wireless charger should easily charge your iPhone 8, iPhone 8 Plus, or iPhone X, even in a thick case up to 5mm, except for if the case is made out of metal.
Qi wireless charging uses a system of magnetic induction coils, which has a transmitter and receiver. If your case is made out of metal, it might have a negative effect on the transmitter's ability to send the signal to your iPhone's receiver. I've read that even a small square metal plate, sometimes used for magnetic car mounts, can bork your charging capabilities, sometimes it will burn your mobile phone and wireless charger. Please remove the metal plate from your phone case if you are using wireless charger!
Because the Qi standard has become so popular (and will definitely increase in popularity now that the iPhone 8 and iPhone X support it), there are companies that try to pass off their products as supporting the Qi standard. For a product to be Qi certified it has to go through a lot of testing to meet the minimum qualifications for certification. It's not entirely unlike products that are MFi certified as opposed to products with statements that they "work with iPhone," and the like. Non-certified wireless chargers will likely have wording such as "Qi compatible" or "works with Qi," instead of stating "Qi certified" or "uses Qi technology." That doesn't mean non-certified wireless chargers are bad. It just means you're sure to get quality and safety if you get a charger that is Qi certified.
There are also multi-coil transmitter charging pads that are wider and able to charge multiple devices at once. More coils does not mean faster or stronger charging. It just means more room for more devices. Apple's upcoming AirPower wireless charger supports charging three devices at once, it is shown charging an iPhone, Apple Watch, and AirPods charging case. We don't know yet whether it will come to market, but we have some good recommendations from sinregeek, you may try some of them.
In your search for the perfect wireless charger for your new iPhone 8, iPhone 8 Plus, or iPhone X, look for a charger that is Qi-certified and you'll have no problem charging your iPhone while it's snugly secured in its case. Cheap chargers that don't specifically state they meet the Qi standard may cause you some case-charging grief or have difficulty with proper alignment. If I've learned anything in life, it's that it is better to spend more up front for high-quality products than to buy cheap and have to replace it soon anyway.
Can you wireless charge with magnetic case?
The metal plates are placed in a specific curved design around the center of the case, one at the top and one at the bottom. This means that the case can work both with the magnetic car dock and with a wireless charging pad without affecting the ability to charge.
Will wireless charging destroy credit card?
If a credit or debit card is placed directly on top of a wireless charger, the magnetic fields could hamper the performance of your contactless feature. In some cases, it will stop working altogether and you will only be able to use chip and pin.
