While the Samsung Galaxy Watch 4 is one of the best smartwatches you can buy, it’s by no means a perfect smartwatch, as we found in our review. First of all, the Galaxy Watch 4 uses WPC-based charging technology and does not technically support standard Qi wireless charging. That said, there’s no shortage of people claiming they can charge their Wearbles with a Qi wireless charger, but it’s kind of a bummer: if you’ve got a Qi charger lying around it might be worth a try, but we definitely wouldn’t rely on this workaround.


Apart from that, Galaxy Watch 4 also supports reverse wireless charging only on Samsung Galaxy flagships with Wireless PowerShare feature. Similarly, you can also charge all previous generations of Galaxy Watches – Galaxy Watch, Watch 3, Watch Sport, Gear S3/Sport, Watch Active and Watch Active 2 – with this feature.

What is Wireless PowerShare?

Wireless PowerShare is a Samsung-exclusive feature found in Samsung’s flagship line of devices such as the Galaxy S, Galaxy Note and Galaxy Z Flip series. It turns the back of the phone into a wireless charger and can be used to charge other devices that support wireless charging. You can use it to add a little juice to your second phone or accessory that supports Qi wireless charging when they’re running low.

How to charge a Galaxy Watch 4 with a wireless charger

  1. Connect the wireless charger to the power adapter.

  2. Place your Galaxy Watch 4 on the watch charging area.
  3. Adjust the clock to perfectly match the charging pad coil marks. This will ensure your watch charges faster and more efficiently.

How to charge a Galaxy Watch 4 with Wireless PowerShare

Samsung’s Wireless PowerShare feature is great for charging other Samsung and most Qi-enabled devices. However, it is only available in Samsung flagships like Z Fold/Flip, S10, S20, S21, S22, Note 10 and Note 20 series. Here’s how to use it.

  1. To open, swipe down from the top of your phone quick settings.
  2. Find and tap Wireless PowerShare tile to turn it on.

  3. Place your Samsung phone on a table face down.
  4. Place your Galaxy Watch 4 in the center of the phone to start charging.

The watch will only start charging when the charging coils are properly aligned. If you don’t see the watch charging after you place it, try readjusting its position.

How to set a battery limit for Wireless PowerShare

  1. Open Settings.
  2. Scroll down and tap Battery and device care.
  3. Beat battery.

  4. Beat Wireless power sharing.
  5. Choose battery limit to change the battery percentage.

If you lost the charging adapter and puck, your options would be — the original Samsung Galaxy Watch wireless charging dock, which sells for $30, or Qi-certified wireless chargers, which sell for around $30-$40 and work with the Galaxy Watch 4.

You can also buy Samsung’s Wireless Charger Duo or Trio, which retail for $60 and $90 respectively, which can charge one/two Samsung devices and a Galaxy Watch 4 at the same time.

Is Wireless PowerShare a good way to charge your Galaxy Watch 4?

No it is not. The fastest way to charge your Galaxy Watch 4 is to use the official wireless charger. Reverse charging can be slow, inefficient, and generate heat.

Not to mention that charging your Galaxy Watch 4 regularly via the PowerShare feature can affect your phone’s battery life in the long run. Therefore, it is recommended that you only use the Wireless PowerShare feature in an emergency.

Samsung and its growing ecosystem

The lack of out-of-the-box Qi wireless charging support on the Galaxy Watch 4 is a bummer, especially for those who own a non-Samsung device with reverse wireless charging support. However, the exclusion of Qi charging is probably one of Samsung’s ways of inviting people into its growing ecosystem, which comes closest to Apple’s in the Android world.

With the Pixel Watch around the corner, it will be interesting to see if it will support Qi wireless charging or follow in Samsung’s footsteps. In any case, the Galaxy Watch 5 is also coming, and we’re hoping Samsung will add Qi wireless charging as standard. If you are looking to buy a wireless charger, here are some of the best wireless chargers for your Samsung devices that you can buy right now.
