Running out of battery on the go can be a major hassle. Even with power banks, you might forget them. Luckily, newer Samsung phones offer a backup: Samsung Wireless Power Share.
Phones that can both give and receive power include the S20‑26 series, S10, Note 20/10, Z Fold, Z Tri Fold, and Z Flip. Others, like the S7, S8, S9, and Note8/10, can only receive. To start, swipe down, tap Wireless Power Share, and place devices back‑to‑back.
The feature works until the sharing phone falls below 30 percent (it needs >30% to begin). The system charges any WPC Qi‑certified phone, including i Phones and many brands, plus Samsung wearables such as Galaxy Ring, Buds, and Watches (except Watch7). It’s handy in emergencies, but slower than portable chargers, less efficient, and generates heat that can stress lithium‑ion batteries.
In short, Samsung Wireless Power Share is a solid last‑ditch option when no other power source is at hand, despite its speed and heat drawbacks.
