What Is Reverse Wireless Charging?
Wireless charging is pretty straightforward—it's charging without a wire. But reverse wireless charging, what's that?
This is a feature that has made its way into many premium phones, and it goes by many names: "battery share," "power sharing," and even "Wireless PowerShare." Regardless of the name, is this a must-have feature on your next phone?
How Reverse Wireless Charging Works
Wireless charging, also known as inductive charging, is the ability to charge a device using electromagnetic induction via two metal coils. In the case of smartphones, one coil is in the wireless charger, and the other is in the back of your phone.
Reverse wireless charging enables your phone to send power back the same way it came in, so that you can charge another device. You do so by placing the second device, such as another phone or a pair of battery-powered earbuds, onto the back of your phone. This is one of the hidden ways to wireless charge a phone.
Both devices must have a metal coil, or put another way, both devices must be capable of wireless charging. You cannot use reverse wireless charging to power a device that must be plugged in to charge.
How to Use Reverse Wireless Charging
There's a good chance you need to manually enable reverse wireless charging before you can plop another phone onto the back of yours.
How to enable this feature varies by device, with different manufacturers using different names for the functionality. In most cases, you can find the feature by looking under Settings > Battery.
On a Google Pixel phone, go to Settings > Battery > Battery Share and hit the toggle.
On the Motorola Edge+, by contrast, this feature is found under the name "Power Sharing." You enable the feature by going to Settings > Battery > Power Sharing.
Meanwhile, reverse wireless charging is known as Wireless PowerShare on a Samsung Galaxy device.
On an iPhone 15 or later, look for a toggle to enable reverse wireless charging after heading to Settings > Battery > Wireless
