A phone has a copper coil with is a receiver and the charger has a copper coil which is a transmitter, when they are aligned they create an electromagnetic field which allows power to pass through and recharge the devices battery.

No it is not.

Apple iPhone: every iPhone since iPhone 8 (2017), including iPhone Air, iPhone 17, 17 Pro, and 17 Pro Max. iPhone 12 and later add MagSafe magnetic alignment. iPhone 16 and later support Qi2 25W speeds on a Qi2 25W certified charger.

Samsung Galaxy: every Galaxy S series flagship from S6 onward (S6 through S26), every Galaxy Note from Note 5 on, and the Galaxy Z Fold and Z Flip foldables. The S25 and S26 series support native Qi2 charging. The S26 Ultra reaches 25W with a Qi2 25W charger (S26+ at 20W, S26 at 15W).

Google Pixel: Pixel 3 through Pixel 10 series, including Pro and Pro XL variants. Pixel 10, 10 Pro, and 10 Pro Fold add built-in Qi2 magnets. Pixel 10 Pro XL reaches 25W on a Qi2 25W charger.

Other Android: OnePlus 13 and HMD Skyline support Qi2 at 15W. Most other Qi-enabled Androids work at 5-7.5W on a standard Qi pad.

Once wireless charger is plugged into a power source, to charge your device all you need to do is place it down on top of the charger, making sure it’s cantered and charging will commence. Charging will be indicated by an Led light or animation on your phone screen.

Wireless charging stands are similar to charging pads, but hold the device at an angle so it can be viewed while it charges. They work by using inductive charging, which transfers energy wirelessly from the charger to the device being charged. The charger contains a coil of wire that creates an electromagnetic field, and the device being charged contains a coil that picks up this field to charge the battery. Charging stands use the Qi, MagSafe, Qi2, or Qi2 25W standard. Qi2 and MagSafe stands add magnetic alignment for iPhone 12 and later; Qi2 25W stands reach 25W on iPhone 16 and later.

The main differences between iPhone and Samsung wireless chargers come down to the wireless standard, the maximum charging speed, and the magnetic alignment.

1. Wireless standard

• iPhone: Qi (iPhone 8-11), MagSafe (iPhone 12 and later), Qi2 25W (iPhone 16 and later, plus iPhone Air)
• Samsung: Qi (Galaxy S6 through S24), Qi2 (Galaxy S25 and S26 series), Qi2 25W (Galaxy S26 Ultra)

2. Maximum charging speed

• iPhone: up to 7.5W on Qi, 15W on MagSafe, 25W on Qi2 25W (iPhone 16 and later; iPhone Air caps at 20W)
• Samsung: up to 15W on most flagships, 25W on Galaxy S26 Ultra with a Qi2 25W certified charger (S26+ at 20W, S26 at 15W)

3. Magnetic alignment

• Samsung: built-in Qi2 magnets on Galaxy S25 and S26 series; earlier Galaxy phones need a Qi2-ready case for snap-on magnetic alignment

4. Cross-brand compatibility

• Most modern Qi2 and Qi2 25W chargers work for both iPhone and Samsung. A single Qi2 25W certified charger delivers the fastest available wireless speed on both an iPhone 16 and later and a Galaxy S26 Ultra. For more, see how MagSafe and Qi2 compare.

Wireless charging speed depends on the wireless standard, the charger, and the device. Here are the speed tiers from slowest to fastest:

• Qi (standard): up to 7.5W on iPhone, up to 10W on Samsung
• MagSafe: up to 15W on iPhone 12 and later
• Qi2: up to 15W on iPhone 12 and later, Galaxy S25/S26, Pixel 10, OnePlus 13, HMD Skyline
• Qi2 25W (also called Qi2.2): up to 25W on iPhone 16 and later, Galaxy S26 Ultra, Pixel 10 Pro XL; up to 20W on iPhone Air and Galaxy S26+

Speed summary by device:

• iPhone 8-11: up to 7.5W
• iPhone 12-15: up to 15W (MagSafe)
• iPhone 16 and later: up to 25W (Qi2 25W certified charger)
• iPhone Air: up to 20W (Qi2 25W certified charger)
• Galaxy S6 through S24: up to 15W
• Galaxy S26 Ultra: up to 25W (Qi2 25W certified charger)
