In today’s fast-paced technological world, features like wireless charging are becoming a staple in premium smartphones. Among various smartphone brands, Samsung has emerged as a leader in offering innovative features that cater to users’ needs. One such feature that stands out is reverse wireless charging. This functionality allows users to charge other devices, such as smartphones, earbuds, or wearables, simply by placing them on the back of their Samsung phone. In this article, we will delve into which Samsung phones support reverse wireless charging, how it works, its benefits, and tips for using the feature effectively.
Understanding Reverse Wireless Charging
Reverse wireless charging, also known as PowerShare, enables a smartphone to act as a charging pad for other compatible devices. This means you can charge your friend’s phone or top up your Galaxy Buds without needing additional cables or power banks.
How Does Reverse Wireless Charging Work?
The technology behind reverse wireless charging is based on the principles of Qi wireless charging. Here’s how it operates:
Electromagnetic Induction: The phone’s back contains a coil that creates an electromagnetic field when activated. When another device is placed on the phone, the electromagnetic field transfers energy to the receiving coil in the other device.
Charging Process: Once in contact, the receiving device begins charging automatically. The charging speed typically varies depending on the devices involved and the configuration of the charging system.
Smart Detection: Samsung devices have built-in sensors that can detect when another compatible device is placed on the back, ensuring that only the right devices can be charged.
Why Use Reverse Wireless Charging?
Reverse wireless charging offers numerous advantages, particularly for users who are constantly on the go. Here are some compelling reasons to utilize this technology:
Convenience: No need to carry extra cables or power banks; simply place your device on the back of a compatible Samsung phone to charge it.
Multi-Device Support: Whether it’s your friend’s phone, a smartwatch, or wireless earbuds, reverse wireless charging works with a range of devices.
Eco-Friendly: Reducing the need for disposable batteries and chargers leads to a lesser environmental impact.
Emergency Charging: In instances where you’ve run out of battery, being able to charge another device using your phone can be a lifesaver.

What is reverse wireless charging on Samsung phones?
Reverse wireless charging is a feature found in select Samsung smartphones that allows users to charge other devices wirelessly by simply placing them on the back of the phone. This technology utilizes Qi wireless charging, enabling you to power up compatible devices such as wireless earbuds, smartwatches, and even other smartphones without needing a traditional charger.
This feature can be particularly useful in situations where you may not have access to a charging cable or power outlet. With reverse wireless charging, you can quickly lend a portion of your smartphone’s battery life to another device, making it a handy tool for sharing power with friends or for charging your on-the-go accessories.
Which Samsung phones support reverse wireless charging?
Several Samsung smartphone models feature reverse wireless charging capabilities. Notable models include the Galaxy S10 series, Galaxy S20 series, Galaxy S21 series, Galaxy S22 series, and Galaxy S23 series. Additionally, the Galaxy Note series, specifically the Note 10 and Note 20, also support this functionality, making it a common feature in Samsung’s flagship offerings.
To check if your specific Samsung phone model includes reverse wireless charging, you can refer to the official Samsung website or check the specifications in your device’s settings. This feature may also be labeled as “Wireless PowerShare” in the device settings, so it’s worth looking out for that terminology.
How do I enable reverse wireless charging on my Samsung phone?
Enabling reverse wireless charging, or Wireless PowerShare, on your Samsung phone is a straightforward process. Begin by swiping down from the top of your screen to access the Quick Settings panel. Look for the Wireless PowerShare icon, which resembles two overlapping circles, and tap on it to activate the feature. You may also find this option in the device settings under “Connections” or “Battery.”
Once activated, you’ll see a prompt indicating that reverse wireless charging is active. To use it, simply place the device you want to charge on the back of your Samsung phone, ensuring the two devices align properly for optimal charging. The charging setup will begin shortly, and you can monitor the charging process on your screen.
Is there a limit to how much power I can share using reverse wireless charging?
Yes, there are limitations when using reverse wireless charging on Samsung devices. The maximum wattage for reverse wireless charging is generally around 4.5W, which is significantly lower than the typical charging speeds you’d experience when charging your Samsung phone with a wired charger or even standard wireless charging for your phone. This reduced power output means that charging another device using reverse wireless charging can be a slower process.
Additionally, the amount of power you can share will also depend on your Samsung phone’s remaining battery life. If your phone’s battery is low, you might find that it limits the capability to share power as a way to conserve remaining energy. It is advisable to use this feature when your phone still has a moderate amount of battery life available.
Can I use reverse wireless charging to charge my Samsung phone?
Reverse wireless charging on Samsung devices is designed primarily for charging compatible accessories such as smartwatches and earbuds. While technically you could place another Samsung phone on the back of a device with reverse wireless charging capabilities, it may not be an efficient or effective method to charge a phone. The power transfer will be relatively slow, making it impractical for regular use.
Moreover, using your Samsung phone to charge another phone could lead to quicker depletion of your device’s battery, which is not ideal if you need your phone for calls or other essential tasks. It’s advisable to keep reverse wireless charging for smaller, less power-hungry devices rather than other smartphones to ensure you’re not compromising your own battery life.
How can I ensure optimal charging performance with reverse wireless charging?
To achieve the best charging performance when using reverse wireless charging, ensure that both devices are aligned correctly. Placing the device you want to charge in the center of the back of your Samsung phone can help create a more efficient charging connection. Avoid using thick cases on either phone, as these can interfere with the wireless charging process.
Additionally, keep in mind the battery levels of both devices. For ideal performance, it’s beneficial to use reverse wireless charging when your Samsung phone is above 20% battery. Also, reduce background activities on your main device while using reverse wireless charging, as multitasking can slow down the charging speed as your phone divides its power across functions.
Are there any drawbacks to using reverse wireless charging?
While reverse wireless charging offers convenience and can be very useful, there are some drawbacks associated with this feature. As mentioned earlier, the charging speed is significantly slower compared to traditional wired charging, so it might not be the best solution if you’re in a hurry. Users may find that it takes a long time to charge devices, especially larger ones, such as tablets or smartphones.
Another potential downside is that using reverse wireless charging can quickly drain the battery of your Samsung phone. If you frequently rely on this feature for power sharing, you may find that your main device requires more regular charging sessions, which can compromise its longevity and overall battery health over time. Hence, while it is a handy feature, moderation in use is key.
