Let‘s get started and cut the cord from your Android device once and for all!
What Exactly is Wireless Charging?
Wireless charging, also known as inductive charging, uses electromagnetic induction to transfer power between two objects – a charging pad (the transmitter) and a receiver (either built into the device or attached to it).
The transmitter pad contains copper coils that generate an oscillating magnetic field when current passes through them. The receiver contains similar copper coils that convert the magnetic energy back into electric current to charge the device‘s battery.
This wireless power transfer only works over short distances of up to 4 cm. But that‘s all that‘s needed to charge your phone when placed directly on a pad.
The most common wireless charging standard used by Android phones is called Qi (pronounced chee). It was developed by the Wireless Power Consortium and is found in products from Samsung, LG, Sony, Motorola, and other brands.
There‘s also a less common competing standard called Powermat. An example device that supported Powermat is the older Nokia Lumia 920 phone.
As of 2022, Qi is the dominant player, making up over 80% of wireless charging devices. So if you want maximum compatibility, look for Qi-certified chargers and phones.
Now let‘s move on to checking if your Android device even supports wireless charging in the first place.
Does Your Android Support Wireless Charging?
Wireless charging is still considered a premium feature only available on higher-end Android phones. Mid-range and budget phones often lack native wireless charging capabilities.
Here are some popular Android models that support Qi wireless charging out of the box:
- Samsung Galaxy S22 Series
- Samsung Galaxy Z Fold 3
- Google Pixel 6 Series
- OnePlus 9 Series
- LG Wing 5G
- Sony Xperia 1 III
And examples without built-in wireless charging support:
- Samsung Galaxy A53 5G
- Google Pixel 5a with 5G
- OnePlus Nord N20 5G
- Motorola Moto G Stylus 5G
To check if your specific Android phone model supports wireless charging, consult the official user manual or visit the manufacturer‘s website. You can also search "[your phone model] wireless charging" online to find relevant info.
If your phone lacks integrated wireless charging, don‘t fret. You can add wireless charging capabilities by using a wireless charging receiver, which is a thin adapter that sticks to your phone‘s back. We‘ll cover how to set this up later in the guide.
First, let‘s go over how to pick the right wireless charging pad for your Android device.
Choosing the Best Wireless Charger for Your Android
Once you‘ve confirmed your Android works with wireless charging, it‘s time to pick out a charging pad. Here are the key factors to consider when choosing a wireless charger:
Charging Speed
Faster wireless charging requires higher wattage. Look for chargers rated at 10W or above (up to 15W max). Match the wattage level that your Android device supports for the fastest charging speed.
Qi Charging Standard Comparison
| Output Power | Charging Speed |
|---|---|
| 5W | Slow |
| 7.5W | Moderate |
| 10W+ | Fast |
Size of Charging Pad
Consider the dimensions of the charging pad versus the size of your phone. You want the entire back of your phone to make contact with the pad. Larger pad sizes give you more leeway in phone placement.
Single Device vs. Multi-Device
Some wireless chargers have a single charging coil, while others have multiple coils to charge 2 or 3 devices simultaneously. Choose based on your needs.
Stand-Up Design
Pads with an angled stand design let you see the screen while charging. This is convenient but costs a bit more.
Additional Features
Some chargers have cooling fans, foreign object detection, temperature sensors, and other premium features. Decide if you need any of these extra perks.
Brand Reputation
Stick with reputable brands like Samsung, Anker, Belkin, Mophie, etc. for safety, quality, and reliability. Avoid no-name knock-offs.
Now let‘s go over how to setup wireless charging on your Android device…
How to Set Up Wireless Charging on Android
These steps will cover how to start using your new wireless charger with your Android phone:
1. Position the Charging Pad
Place your wireless charging pad on a flat surface like a nightstand or desk. Make sure that the surface and surrounding area are clean and free of debris.
The pad should be close enough to an outlet so that the included power adapter cable can reach.
2. Plug in the Wireless Charger
Connect the wireless charger‘s power adapter cable to the charging pad base.
Plug the adapter into a wall outlet or power strip. Use a surge protector outlet for added safety.
Some charging pads have an LED indicator that will light up when connected to power.
3. Place Your Android Phone on the Pad
Gently set your phone face up on the center of the wireless charging pad.
The location of the wireless charging coil varies by device, but it‘s usually centered on the phone‘s back.
For maximum efficiency, the charging coils in the pad and phone must align closely. The phone‘s back and the pad surface should make full contact.
4. Check the Charging Status
Once properly positioned on the pad, your Android phone will start charging automatically.
The charging icon will display on your lock screen along with the percentage indicator.
To confirm it is charging wirelessly, swipe down your notification panel. It should say "Wireless charging" or "Fast wireless charging".
Some wireless chargers also have a LED that glows a certain color when charging is in progress.
And that‘s it! Your Android phone is now charging wirelessly. Pretty cool, right?
The process is just as seamless when using a wireless charging receiver. Simply attach the thin receiver to your phone‘s back, connect its cable to your charging port, and place on the wireless pad.
Next, let‘s go over some troubleshooting tips in case you run into any wireless charging issues.
Troubleshooting Wireless Charging Problems
Wireless charging on Android is usually a smooth process, but glitches can occur occasionally. Here are some common problems and fixes:
Problem: Charging seems slow or intermittent.
Solution: The charging coils may be misaligned. Carefully reposition your phone so there is maximum surface contact with the pad. Remove any thick phone case that may cause interference.
Problem: The phone doesn‘t charge at all on the wireless pad.
Solution: First, double check that the wall outlet/power strip is working by plugging in another device. Try a different charging cable if your wireless charger has a detachable one. If the issue persists, your charging pad may be defective.
Problem: The phone gets hot while charging wirelessly.
Solution: Some warmth is expected, but excessive heat can damage your battery. Make sure your phone is centered on the pad, remove any case, and avoid charging in hot ambient temperatures. If it continues overheating, switch to a different wireless charger.
Problem: The charging pad is causing interference with WiFi, Bluetooth, or cellular reception.
Solution: Try moving the charger pad at least 1-2 feet away from your router or mobile devices to eliminate interference. This issue is rare but can occur if the pads are placed too closely together.
If problems persist even after troubleshooting, you may need to exchange the faulty component – either the charging pad or the phone‘s wireless charging receiver. Contact the manufacturer for assistance.
Now let‘s dive into the pros, cons, and other key facts about wireless charging…
