Samsung Galaxy Phones Can Wirelessly Charge Other Devices
Many newer Samsung Galaxy phones with the Wireless PowerShare feature can wirelessly charge other phones, earbuds and smartwatches. Charging is slow and generates a lot of heat, so it is best treated as a last resort.
When a phone battery is nearly empty and no charger is at hand, Samsung's Wireless PowerShare feature can help. It lets one Galaxy phone wirelessly pass power to another phone or to compatible devices such as earbuds and smartwatches.
Which phones support it
Galaxy S20 to S26 series models can both give and receive power, as can the S10, the Note 20 and Note 10 series, the Z Fold series, the Z TriFold and the Z Flip series. Some older models can only receive power and cannot share it: the S7 and S7 Edge, S8 and S8+, S9 and S9+, Note8 and Note10.
How to turn it on
On the phone that will supply power, swipe down to open the notification panel and tap Wireless PowerShare. Then place the device to be charged back-to-back with the sharing phone. Charging continues until the sharing phone falls below 30 percent battery. The sharing phone must also be above 30 percent to start the feature.
If the connection fails, remove the phone case and any other accessories, clean the back of the phone, and place the charging device in the center of the sharing phone.
What it can charge
PowerShare can charge any WPC Qi-certified phone, including iPhones and models from other brands. It also works with many Samsung wearables: the Galaxy Ring, most Galaxy Buds and most Galaxy Watch models. Some, such as the Watch7, are exceptions.
Drawbacks
Wireless charging wastes considerably more electricity than wired charging, so PowerShare is slow and cannot compete with a simple portable charger. Part of the energy is lost as heat. The feature produces far more heat than wired charging, which can harm both batteries, since high heat exposure degrades lithium-ion cells. Even so, it remains a useful last-ditch option when no alternative is available.
