How Does Qi Wireless Charging Work, Your iPhone X, iPhone 8, or iPhone 8 Plus are designed with internal charging coils and glass backs. These features allow Qi wireless chargers to use electromagnetic induction to replenish your devices battery via oscillating electromagnetic energy fields. This process transmits energy from charging coils in the Qi charging station, through your iPhone's glass back, to the coils within your iPhone. Qi wireless charging relies upon what is known as a resonant inductive coupling, which connects the Qi sender (your charging pad) with the Qi receiver (your iPhone, or other Qi-enabled device).

The Qi wireless charging station emits an initial test signal, which checks for your Qi-compatible device and determines the energy required to recharge its battery. Once the connection is established, charging commences and continues as long as the devices remain in contact with one another. Qi wireless charging discontinues once your iPhone is charged, and a Qi charging station only activates when a Qi-compatible device is placed on it so it’s not constantly emitting low-level electromagnetic radiation. Does wireless charging work with a phone case,

Thankfully, the answer is yes; Qi charging stations power up your iPhone even through a case, with a few exceptions. A very important thing to remember about Qi charging pads—never place anything on them that will disrupt the electromagnetic field they produce.

This leaves tons of Qi-compatible iPhone case options on the table, and as Qi wireless charging becomes ubiquitous, we're sure to see more choices enter the market.

Wireless charging pads come in different sizes, and many have multiple coils to enable friends and family to share the same station. With Qi-certified charging stations popping up everywhere from airports to hotels, and even being included in car and furniture manufacture, you won't be at a loss for charging options. If a Qi charger is nowhere to be found it's not a problem, as your iPhone can still charge with a cable.

Qi charging is a non-proprietary technology, which means that there are lots of non-Apple wireless charging options available. Prices begin at ten dollars; roughly equivalent to the cost of a lightning cable. Your iPhone can go from a zero to a fifty percent charge in about half an hour with a lightning cable and the proper adapter. Wireless chargers can't match this speed, charging only about a quarter of the way in thirty minutes.

Wireless charging can cause your iPhone to heat up; and if that happens, your charging station will halt the charge until the device cools off. Also, any notifications that cause your iPhone to vibrate may shift it off the charging coil and stop the charge. This can be fixed by using Do Not Disturb mode.

As mentioned before, certain accessories may prevent your iPhone from charging wirelessly—very thick cases, magnetic cases, or wallet cases containing RFID or magnetic strip items may need to be removed. If you have a PopSocket, it will need to come off before charging as well. Now that you know how Qi wireless charging works for your iPhone, and which accessories are Qi compatible, it's up to you to decide whether or not Qi is right for you. Will one or more inductive chargers improve your productivity, or is it easier to stick to the familiar lightning charger for now, Maybe a Qi wireless charger for overnight charging and a lightning cable for your on-the-go needs, It's up to you!
