What is wireless charging?
Wireless charging is the process of electrically charging battery-powered devices and equipment without the need for a wired electrical power connection. It enables the wireless transfer of electrical charge from a charging device or node to the recipient device.
There are three forms of wireless charging which are inductive, radio, and resonance.
Inductive Charging Uses electromagnetic waves to transfer energy and charge devices wirelessly similar to radio.
radio charging uses wireless radio waves to transfer energy to small devices and equipment while resonance charging consists of a sending copper coil and a receiving copper coil at the device end Used for charging large devices and equipment such as laptops, robots, cars, and more.
How does wireless charging works with your device?
Wireless charging is based on the principle of magnetic conduction. i.e. the chargers use magnetism to transfer energy to a receiver in the back of the phone through electromagnetic induction(an inductive coil is placed in the charging pad that creates an oscillating electromagnetic field while the receiving coil in your device helps convert that magnetic field back into electricity to charge up the battery).
Practically you plug your wireless charger into the power outlet, Then you place your phone on the charger. The current coming from the power outlet will move through the wireless charger and create a magnetic field which in turn creates a current in the coil inside the device lying on the wireless charger which is then converted to electrical energy to charge up your device battery.
There is two standards for wireless charging design for a portable gadget which are the wireless power consortium’s QI standard (pronounce “chee”) and PMA or AirFuel Alliance Resonant standard.
Pros and cons of wireless charging
Pros of wireless charging.
• With wireless charging, all you need is one cable plugged into the charging mat — no more multiple cables for multiple devices, You can use the same charging mat for all your devices
• Fewer cables mean less clutter, frees up your phone port for other uses, reduces the likelihood of power surge to your phone, can charge multiple devices at once with larger charging pads
• Good for public charging because nothing plugs into your phone; available at some hotels, restaurants, and coffee shops
• Auto-off: Once the device is fully charged, the wireless charger shuts off, resulting in saved energy, a safer charge, and less need to worry about overheating your battery
• Charging pads last longer than cables so create less trash for landfills
Cons of wireless charging
• Must line up your device and charger with precise accuracy on some chargers, you can inadvertently move the device out of alignment without knowing it (especially if you’re charging in a drawer)
• Wireless charging typically takes 30-80% longer to fully charge your device than a cable.
Keep in mind: how you place your device on the mat can affect how long it takes to charge and even in an ideal setup, 20% of the power running through your device will be wasted — not great in terms of conserving energy.
• Your device has to stay on the meat while it’s charging, meaning you can’t pick it up and use it in the way you can when it’s plugged into a charging cable
• It’s more expensive: Wireless chargers are a relatively new technology with a hefty price tag, especially compared to cables
• Not as portable as cables; larger pads can be awkward to carry around.
How to fix your wireless charger if not work
Wireless charging looks so simple. You just set your phone on the charger and walk away. But in practice, it can be a little tricky. If you’re having trouble getting your phone to wirelessly charge, here are a few fixes to try.
• The most common issue is that the charging components in the phone and the charger don’t line up When setting your phone on a wireless charger, keep your eye on the phone and wait for a message on the screen that tells you it’s charging. If you don’t see the message, try re-positioning your phone.
• Check if your wireless charger is properly plugged in, we call this a wireless charger but it does not mean that it can charge your device without getting any power supply, right? So here, you may also want to check if the charging pad is properly plugged in on your device and of course check if it is connected to a power source
• Restart your device, this will be your first choice of action once your device is not charging using your wireless charger. Doing a restart is actually the basic solution that will be able to help you fix those systems glitches which could be a cause as to why your device is not wirelessly charging.
• If you are using case protection for your device, you might as well take it off. This is because it could be one reason as to why your device is not charging properly using your wireless charger.
• Update your device software, a software issue could affect the wireless charging, making it slower or not charging. Sometimes you might see a black screen or white screen while charging, or your phone is frozen.
• If all the methods above are not workable for your device, chances are that your wireless charger is broken. Use another wireless charging pad or use a battery case for fast wireless charging then.
