What is reverse wireless charging on the Galaxy Z Flip 6

How Reverse Wireless Charging Works

1. Activation: To enable reverse wireless charging, navigate to the Settings menu, select Device care, and then choose Battery. From there, you can find the Wireless PowerShare option. You can also set a battery limit for sharing power, which cannot exceed your current battery percentage[1][3][6].

2. Charging Process: Once activated, place the device you want to charge (like earbuds or another smartphone) on the back of the Z Flip 6, ensuring their backs are facing each other. The charging will commence automatically[1][2].

3. Charging Speed: The reverse wireless charging on the Galaxy Z Flip 6 operates at a rate of 4.5W, which is relatively slow compared to standard charging speeds. This feature is best suited for small devices like earbuds or smartwatches rather than larger devices[3][6].

Practical Uses

- Emergency Charging: This feature is particularly useful for quickly topping up smaller accessories when you're on the go and your phone has sufficient battery life[3][6].
- Convenience: It eliminates the need for additional cables or chargers, making it a convenient option for users who frequently use wireless accessories[1][4].

Limitations

- Battery Drain: Utilizing reverse wireless charging will deplete the phone's battery, so it's advisable to use this feature judiciously[3][6].
- Slow Charging Rate: The 4.5W charging speed is slower than many wired and even some standard wireless charging options, making it less ideal for larger devices[3][6].

In summary, reverse wireless charging on the Galaxy Z Flip 6 is a handy feature that enhances the device's versatility by allowing it to charge other compatible gadgets wirelessly, albeit at a slower speed suitable for smaller devices.
