What Is Wireless PowerShare?
Wireless PowerShare is a feature found on many Samsung Galaxy smartphones, starting with the Galaxy S10 series and continuing through newer models like the S23, S24, and Galaxy Note 20. It allows your phone to act as a wireless charger for other compatible devices, including earbuds, smart watches, and even other phones.

The technology works by using the phone’s battery to generate a small electromagnetic field, which transfers energy to another device placed on the back of the phone. It’s not as fast as plugging in, but it’s incredibly convenient for quick top-ups or emergency charging.
For smart watch charging, this means you can place your Galaxy Watch on the back of your Samsung phone and let it draw power—no cables, no adapters, just two devices working together.

Step-by-Step Guide: How to Charge Your Smart Watch with a Samsung Phone
Now that you know your devices are compatible, let’s get into the actual process. Charging your smart watch with your Samsung phone is simple, but there are a few key steps to follow for the best results.
Step 1: Check Your Phone’s Battery Level
Before you start, make sure your Samsung phone has enough battery to share. Samsung recommends at least 30% battery to use Wireless PowerShare. If your phone is too low, it may not activate the feature or could shut down during charging.
Why? Because PowerShare drains your phone’s battery quickly. If you start with 30%, you might only get 10–15% transferred to your watch before your phone drops to 15%—and then it will stop sharing power to protect itself.
Step 2: Enable Wireless PowerShare on Your Phone
Wireless PowerShare is not always turned on by default. Here’s how to enable it:
- Swipe down from the top of your screen to open the Quick Settings panel.
- Look for the Wireless PowerShare icon (it looks like a battery with waves coming out).
- Tap it to turn it on. If you don’t see it, tap the three dots or “Edit” button to add it to your panel.
Alternatively, you can enable it through Settings:
- Open the Settings app on your Samsung phone.
- Tap Battery or Battery and device care.
- Select Wireless PowerShare.
- Toggle the switch to On.
Once enabled, your phone is ready to share power.
Step 3: Prepare Your Smart Watch
Make sure your Galaxy Watch is clean and free of dust or debris. Dirt on the back of the watch or the phone can interfere with charging. Also, remove any thick or metal watch bands, as they might block the charging signal.
If your watch has a protective case, remove it. Most cases are fine, but bulky or magnetic ones can disrupt the connection.
Step 4: Align the Watch on the Phone
This is the most important step. Proper alignment ensures efficient charging.
- Place your Samsung phone face down on a flat, stable surface.
- Turn your Galaxy Watch so the back (the side with the sensors) is facing down.
- Position the watch in the center of the phone’s back.
- The charging coil on the watch should align with the coil on the phone—usually near the top or middle.
Tip: On most Galaxy Watches, the charging coil is in the center of the back. On Samsung phones, it’s typically near the top third of the device. Try placing the watch so its center matches the upper half of the phone.
If you’re unsure, gently move the watch around until you feel a slight magnetic pull or see a charging icon appear on the watch screen.
Step 5: Start Charging
Once the watch is properly aligned, charging should begin automatically. You’ll see a charging icon on your watch screen (usually a battery with a lightning bolt). Your phone may also show a notification confirming PowerShare is active.
Leave both devices undisturbed during charging. Moving them too much can break the connection.
Step 6: Monitor the Charging Process
Charging via Wireless PowerShare is slower than using a dedicated charger. Expect to gain about 5–10% per 15–20 minutes, depending on the watch model and phone battery level.
Check the watch periodically. If the charging icon disappears, the devices may have shifted. Realign and restart if needed.
Step 7: Stop Charging When Done
Once your watch has enough charge (or your phone drops below 15–20%), you can stop the process.
- Simply remove the watch from the phone.
- Turn off Wireless PowerShare in Quick Settings to save battery.
There’s no need to “disconnect” anything—just separate the devices.
Tips for Better Charging Performance
To get the most out of Wireless PowerShare, follow these practical tips:
Use a Flat, Stable Surface
Charging works best when both devices are on a flat table or desk. Avoid doing this in your hand or on a soft surface like a bed, where the devices might shift.
Keep Devices Cool
Heat can reduce charging efficiency. Don’t use PowerShare in direct sunlight or after heavy phone use (like gaming or video calls). Let both devices cool down first.
Charge in Short Bursts
Since this method drains your phone’s battery, use it for quick top-ups—like adding 10–20% to your watch—rather than full charging sessions.
Update Your Software
Make sure both your phone and watch are running the latest software. Samsung often improves PowerShare performance through updates.
Use Original or Certified Accessories
If you’re using a third-party watch band or phone case, ensure it’s not blocking the charging coils. Samsung-certified accessories are safest.
Troubleshooting Common Issues
Sometimes, charging doesn’t work as expected. Here’s how to fix the most common problems.
Issue: Watch Won’t Charge
Possible Causes & Solutions:

- Software bug: Update your watch’s software via the Galaxy Wearable app.
Is It Safe to Charge Your Watch This Way?
Yes—charging your smart watch with a Samsung phone is safe when used correctly. Samsung designed Wireless PowerShare with built-in protections:
- It automatically stops if the phone overheats.
- It shuts off when the phone battery drops too low.
- It prevents overcharging of the watch.
