In many respects, the Galaxy S20 series is the culmination of mobile technologies Samsung has been iterating upon for over half a decade. Wireless charging is no exception as with the Galaxy S20's Wireless PowerShare feature, Samsung allows you to wirelessly charge other devices with your phone.
Samsung's 2019 flagships were the first devices to come with Wireless PowerShare and the company has retained the feature for the Galaxy S20 lineup as well.
Samsung Wireless PowerShare explained
Much like its name suggests, Wireless PowerShare allows the Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra to reverse wireless charge other devices. The feature isn't just limited to Samsung-made handsets and gadgets. Devices that support the Qi charging standard can be wirelessly charged using these handsets.
Be that as it may, Samsung's always quick to point out that Wireless PowerShare has been specifically designed for its select few products, primarily the Galaxy Watch Active 2 and Galaxy Buds+.
Even in ideal circumstances, the solution can't really compare to contemporary fast wireless chargers which support speeds of up to 15 watts. In contrast, the wireless charging coil found inside the Galaxy S20 line delivers less than half of that performance, which makes the functionality not something to rely on an everyday basis, but it's nice to have the option should you need to add some juice to your Galaxy Buds+ when you're on the road.
How to use Wireless PowerShare on the Galaxy S20
Samsung's proprietary implementation of reverse wireless charging can be accessed from the Settings app, but the easiest way to enable it on any Galaxy S20 model is from the notification panel. Pulling down twice on any screen should do the trick, presenting you with the relevant toggle on the first shortcut page.
Tapping the icon will prompt the phone to start acting as a wireless charger. Do keep in mind that your phone needs to have at least a 30% charge for this to work. With the feature enabled, simply set a compatible device on top of your Galaxy S20, Galaxy S20+, or Galaxy S20 Ultra's rear panel to start charging it. By default, Samsung's flagships will signalize the start of a wireless charging connection via a notification prompt.
On the other hand, interacting with the “Wireless PowerShare” text will lead you to a Settings page dedicated to the service. Choosing the latter lets you tap on “Details” where you'll be greeted with a short tutorial. This screen is also where you can manually set the battery limit for allowing Wireless PowerShare, ranging from 30% to 90%. There's no way to go below the 30% limit.
Even if you're running a custom launcher on top of One UI, the Wireless PowerShare toggle should still be sitting in the notification shade by default. On the off chance that's not the case, just open the Settings app and look up the feature using the search bar at the top.
