Samsung Galaxy phones can wirelessly top up compatible devices in emergencies
Samsung Wireless PowerShare lets some Galaxy phones share battery power wirelessly with another phone or compatible device. It can provide a useful emergency top-up when no charger or power bank is available, though it is slow and inefficient.
The feature works on Galaxy S20–S26 and S10 models, Note 10 and 20 phones, and Z Fold, Z TriFold and Z Flip series; several older Galaxy phones can receive power but not share it. To use it, select Wireless PowerShare from the notification panel and place the devices back-to-back. The sharing phone must have more than 30 per cent charge to start, and sharing stops below that level. It can charge Qi-certified phones, including iPhones, as well as many Galaxy wearables, but heat and energy loss make it less suitable than wired charging or a power bank.
In short
- Some Galaxy phones can wirelessly share battery power.
- Sharing starts above 30 per cent and stops below it.
- It works with Qi phones and many Galaxy wearables, but slowly.
Explained simply
Wireless charging transfers power between devices without a cable, using a standard called Qi that many phones and accessories support. Some Samsung Galaxy phones can also act as a small wireless charging pad, sharing power from their own battery with another compatible device.
Samsung makes Galaxy phones as well as accessories such as watches and earbuds. The sharing feature can help when a device is nearly out of charge and no charger is available, but it uses the phone’s battery and works more slowly than plugging in.
