What Wireless PowerShare does
Wireless PowerShare is a feature available on select Samsung Galaxy devices that enables a phone to wirelessly charge other Qi-certified devices. This includes other phones (even iPhones), Samsung Galaxy earbuds, smartwatches, and the Galaxy Ring. The feature is designed as a backup charging method rather than a primary solution.
According to Engadget, the process involves swiping down to open the notification panel, tapping the Wireless PowerShare icon, and placing the device to be charged back-to-back with the Samsung phone. The feature automatically stops sharing power when the host phone’s battery drops below 30 percent to prevent complete drainage.
Compatible devices
Not all Samsung Galaxy devices support Wireless PowerShare, and some can only receive power rather than share it. Phones that can both share and receive power include the Galaxy S20 through S26 series, S10, Note 20 and Note 10 series, Z Fold, Z TriFold, and Z Flip series.
Devices like the Galaxy S7, S7 Edge, S8, S8+, S9, S9+, Note8, and Note10 can receive power but cannot share it. Wireless PowerShare also works with most Samsung wearables, such as the Galaxy Buds and Galaxy Watches, though some models like the Watch7 are excluded.
Efficiency and battery impact
Wireless PowerShare is less efficient than wired charging, as it generates more heat and wastes more electricity. Engadget notes that this heat can degrade lithium-ion batteries over time, making the feature less ideal for frequent or long-term use.
The feature is best suited for emergencies or situations where no wired charging options are available. Users should monitor battery levels, as the host phone will stop sharing power once its battery drops below 30 percent.
How this fits into Samsung’s ecosystem
Wireless PowerShare complements Samsung’s broader push into connected device ecosystems, including its Galaxy Buds and Galaxy Watches. Earlier this year, Samsung launched the Galaxy Buds On in Korea, targeting the competitive open earbuds market. The feature reinforces the company’s focus on seamless integration across its product lines, even as it competes with other wireless charging standards and brands.
While Wireless PowerShare is not a replacement for wired or high-speed wireless charging, it adds flexibility for users who rely on multiple Samsung devices. For founders and operators in the consumer electronics space, this feature highlights the growing importance of interoperability and user convenience in product design.
What this means
Lazyfounder analysis — our interpretation, not reported fact.
Wireless PowerShare is a practical but limited tool for Samsung users, offering convenience in specific scenarios without replacing traditional charging methods. For founders and operators, it underscores the value of ecosystem integration—even if the technology itself isn’t a breakthrough. The feature’s inefficiencies also serve as a reminder that wireless charging still has room for improvement, particularly in reducing heat and power loss. Companies working on battery technology or alternative charging solutions may find opportunities to address these gaps.
