In today’s fast-paced digital world, smartphones have become indispensable tools that help us stay connected, productive, and entertained. As technology advances, smartphone manufacturers are continually striving to introduce innovative features that enhance user experience. Among these features, reverse wireless charging stands out as a game-changer. This article will delve into what reverse wireless charging is, why it’s beneficial, and which smartphones currently support this feature.
Understanding Reverse Wireless Charging
Reverse wireless charging is a technology that allows smartphones to not only receive power wirelessly but also to act as a power source for other devices. This means you can place another compatible device, such as a smartwatch, earbuds, or even another smartphone, on the back of your phone to charge it.
Key Benefits of Reverse Wireless Charging
-
Convenience: Users no longer need to carry multiple charging cables or portable chargers. If one device runs low on battery, you can use your primary phone to recharge it on the go.
-
Versatility: This technology enables charging multiple devices—from wearables to smaller gadgets—boosting overall usability.
-
Eco-Friendly: By relying on wireless charging, you may reduce the need for disposable batteries and chargers, contributing to a more sustainable tech ecosystem.
How Does Reverse Wireless Charging Work?
Reverse wireless charging uses the same inductive charging technology that powers standard wireless chargers. Here’s a breakdown of the process:
-
Power Transfer: When you place a compatible device on the back of a smartphone with reverse wireless charging capabilities, the primary device emits a magnetic field.
-
Power Reception: The secondary device converts this magnetic field back into electrical energy, thereby recharging its battery.
-
User Activation: On most smartphones, users need to enable reverse wireless charging in the settings to allow power transfer.
This feature is a spectacular blend of convenience and innovation that has found its way into many high-end smartphones.

What is reverse wireless charging?
Reverse wireless charging is a feature that allows a smartphone to act as a charging pad for other wireless charging-enabled devices. This means you can place compatible accessories, such as earbuds, smartwatches, or even another smartphone, on the back of your phone to recharge their batteries. The technology uses the Qi standard, which is widely adopted for wireless charging.
This feature enables users to share battery life on the go, adding convenience to daily routines. For example, if your friend’s earbuds are low on battery, you can use your phone to charge them without needing a power outlet, making it a practical tool for on-the-road charging needs.
Which phones currently offer reverse wireless charging?
Many modern smartphones have incorporated reverse wireless charging capabilities. Notable examples include flagship models from brands such as Samsung (Galaxy S21, S22, S23 series), Apple (iPhone 12 and later), and Huawei (Mate 20 and P30 series). These devices are designed to support this innovative feature, allowing users to share battery life with compatible devices.
Additionally, some brands like Xiaomi and Google have also included this feature in their latest models. As technology evolves, more manufacturers may integrate reverse wireless charging into their devices, making it increasingly common in the smartphone landscape.
How does reverse wireless charging work?
Reverse wireless charging utilizes induction technology, where energy is transferred through electromagnetic fields. When you enable this feature on your phone, it will emit energy through its wireless charging coils. When a compatible device is placed on the back of the phone, the energy is transferred to that device, charging its battery without the need for cables.
To start the charging process, you typically have to activate the reverse wireless charging feature in your phone’s settings. Once activated, simply place the device you wish to charge on the back of your phone, and it should begin charging automatically if it is compatible with the Qi standard.
What accessories can be charged using reverse wireless charging?
With reverse wireless charging, a variety of accessories can be charged as long as they support the Qi wireless charging standard. This includes devices like true wireless earbuds, smartwatches, and some smartphones. Popular examples include Apple’s AirPods, Samsung Galaxy Buds, and various smartwatch models from brands like Fitbit and Garmin.
It’s important to note that not all devices will charge at the same rate. Typically, smaller accessories like earbuds will charge relatively quickly, while larger devices, such as smartphones, may charge more slowly. This feature is most effective for providing a quick power boost rather than a full charge.
Does using reverse wireless charging drain my phone’s battery quickly?
Using reverse wireless charging does consume battery power from the phone that is providing the charge, but the impact varies depending on several factors, including the charge level of both devices and the charging speed. Generally, reverse charging may drain your phone’s battery at a moderate rate if you’re sharing power with another device, especially if it’s a larger device like a tablet or another phone.
To mitigate the drain, it’s wise to use reverse wireless charging strategically. For instance, you can enable this feature when your phone has ample battery left or when you’re at home or in a situation where you can recharge your phone afterward. This way, you can assist others with their charging needs without significantly affecting your device’s battery life.
Is reverse wireless charging safe for my phone?
Yes, reverse wireless charging is generally safe for your phone as it follows the same safety standards as regular wireless charging. Most smartphones equipped with this feature have built-in safety measures to prevent overheating, overcharging, and any potential damage to the device. Manufacturers rigorously test their devices to ensure they can safe operate under these conditions.
However, it is always advisable to use this feature responsibly. For example, avoid charging devices that may not be compatible or excessively heavy, as they can cause pressure on your phone’s back, potentially leading to damage. Ensure that protective cases are compatible and do not interfere with the reverse charging capabilities.
Can reverse wireless charging be used while my phone is charging?
Most smartphones with reverse wireless charging capabilities do not allow this feature to operate simultaneously with regular charging. When your phone is plugged in for charging, it typically prioritizes receiving power, sidelining the reverse wireless charging function. This is due to the available resources and energy management systems within the device.
However, some newer models may offer different functionalities or options for simultaneous charging. Check the manufacturer’s specifications and user manual to know if your model allows for reverse charging while plugged in, as features can vary from one smartphone to another.
How can I enable reverse wireless charging on my phone?
Enabling reverse wireless charging usually involves a few simple steps but may vary slightly by device brand and model. Generally, you can find this feature in your phone’s settings. Navigate to the “Battery” or “Connections” section, where you should see an option for “Wireless PowerShare” or “Reverse Wireless Charging.” Turn the feature on to activate it.
Once activated, you should see an indicator confirming the feature is enabled. To charge another device, simply place it on the back of your smartphone, and it should begin charging automatically, provided it is compatible with wireless charging.
