Experts named the top 6 reasons why Qi2 fast charging is better than regular charging

It looks like 2025 could be the year Qi2 charging finally takes off.

Here are the top reasons why Qi2 is superior to other charging methods. This is&written by experts at Android Police.

High charging efficiency

One of the annoying problems brought by Qi1 was that some devices did not connect well to the charging pad. This is due to the fact that the coils built into the phone are not correctly positioned on the charger; this can happen if the phone has a case on or if there is a loss of contact (trying to charge the phone in a moving vehicle).

Improper alignment can interfere with the signal, resulting in a loss of charging efficiency (energy loss). Qi2 improves on this and is said to increase efficiency to 95%. It uses a magnetic power profile (MPP) based on Apple's MagSafe technology. It keeps the coils between the phone and the charging pad in close contact while locking them in place.

Faster charging speeds

Faster charging speed comparisons only apply to Qi1. Wired charging will suit you better if you're looking for the fastest charging speeds. However, one of the problems with Qi1's rise was how slow it charged. It was also a bit inconsistent. Qi1 charging typically topped out at around 5W — 10W, but sometimes dropped a little lower or higher depending on electromagnetic induction for power transfer, i.e. how well the device was paired with the charger.

Qi2 aims to fix that consistency and keep it at 15W, which can be double or triple that. The better it transfers power, the faster your device charges.

Qi2 adds flexibility and convenience

One reason you want wireless charging is the added flexibility. Wired charging is still the most efficient, but so is connecting an Ethernet cable from your router — not every situation requires that. Wireless charging is similar. Not only does this mean you don't have to worry about future wear and tear when using USB-C, but you can also set up a charging pad anywhere in your home as long as it's on a flat surface.

Adaptive charging speed

Qi2 uses adaptive charging speeds, which means it doesn't have a fixed power output. No extra power is used to charge devices that don't need it. Charging your phone too fast can cause it to overheat.

Extra heat can cause your battery to degrade. Charging will help if you need to strike a healthy balance for fast enough, efficient charging that doesn't generate as much heat. Qi2 does this by intelligently determining your device's power needs to get what it needs without compromising safety.

More support for magnetic accessories

Since Qi2 offers a single charging standard, Android can access iPhone-compatible magnetic accessories. You can buy portable power banks, car mounts, stands, and tripods that support MagSafe compatibility.

You can even use the new iPhone wireless charger with a Qi2-enabled phone.

Backward compatibility with Qi-enabled devices

For more people to embrace the new wireless standard, backward compatibility is a must. The first iteration of Qi came out in 2010. According to the Wireless Power Consortium, there are over 11,000 Qi-certified products in the market today. That's too many devices to ignore. Qi2 will work with Qi-enabled devices, and Qi2 devices will work with Qi1 chargers (note that charging will be slower). You don't have to worry about making any changes after switching to a Qi2-enabled product.

Some manufacturers label devices as Qi2 Ready, rather than as having Qi2 built-in. Qi2 Ready — is a certification that indicates that your device won't have built-in magnets to use for Qi2 charging, but instead can offer functionality through a case or accessory. Qi2 Ready — is an extension that helps devices use Qi2 without infrastructure. Samsung's next flagship, the Samsung Galaxy S25 series, will most likely be Qi2 Ready, meaning you won't be able to use Qi2 wireless charging without a case that supports it first.
