Alongside standard wireless charging, many of Samsung's phones also feature reverse wireless charging. Information technology'south called Wireless PowerShare, and it allows your Milky way telephone to wirelessly accuse Bluetooth accessories and other smartphones that support Qi technology. Below is everything you lot need to know about Wireless PowerShare, how to employ it, and the devices that back up the feature.

All the major Samsung flagships launched over the last few years characteristic Wireless PowerShare. This includes the following devices:

  • Galaxy S10 series
  • Galaxy Note10 series
  • Galaxy S20 series, including S20 FE
  • Galaxy Z Flip/3 and Fold/2/3
  • Galaxy Note20 series
  • Galaxy S21 series, including S21 Atomic number 26
  • Galaxy S22 series

Many other flagship Android phones feature reverse wireless charging, such every bit the OnePlus x Pro and Google Pixel 6 Pro. The characteristic isn't called Wireless PowerShare on those devices as that's Samsung's specific brand name for its tech. Non all phones with wireless charging volition necessarily support reverse wireless charging. You should bank check your phone's spec listing for more than details.

Using reverse wireless charging on your Samsung Galaxy phone is relatively straightforward.

  1. Open Settings.
  2. Scroll downwards and select Battery and device care.
  3. Tap Battery.
  4. Select Wireless ability sharing.
  5. Enable the pick.
  6. Proceed your Galaxy telephone face down.
    • Place the Bluetooth accessory or smartphone in the centre of the device.
    • Y'all need to ensure that the charging coils of both devices align with each other for the wireless ability transfer process to piece of work.
    • If yous face up issues, remove the example from your phone and the device you lot need to accuse and endeavour adjustment them again.
  7. The charging procedure will automatically get-go when the devices are correctly aligned.

An improper alignment tin lead to the charging procedure not working at its full efficiency, so double-bank check the placement of the devices.

Samsung's opposite wireless charging implementation can output 4.5W of power, though the power supplied to the device beingness charged will be lower since wireless charging does not accept 100% efficiency. The power loss from your phone volition not exist proportional, either. For case, if your Galaxy phone loses 30% power during reverse wireless charging, the other device won't gain the same amount of battery power.

Wireless PowerShare will automatically cease when your phone's battery drops below a certain level.

Wireless PowerShare is not fast, though — ideally, you should employ it to pinnacle up your earbuds, smartwatches, or other Bluetooth accessories that back up Qi wireless charging. While it is possible to charge other phones, it volition take a long time. The fastest fashion to charge your Galaxy phone or accessories remains over a wired connection. The iv.5W output is plenty to charge your Galaxy Watch or wireless earbuds since fifty-fifty their bundled adapter supplies the same power. I frequently use my Galaxy S21 to wirelessly charge my Milky way Watch4 when traveling — a full top-upwardly takes around 2 hours. This way, I don't need to carry the Spotter's charger with me.

With phones, though, information technology is a different story altogether. Despite reverse wireless charging an iPhone with my Galaxy S22 Ultra for nearly 1.v hours, the old just gained virtually 38% battery. And this was enough to deplete the Ultra's battery from 92% to 31%.

Yous can use Wireless PowerShare while your Milky way phone itself is charging, though information technology will superlative upward at a slower stride.

Wireless PowerShare is a helpful feature to take when traveling, and you forget to carry your smartwatch's charger. Information technology is only good for phones to give them some boosted juice in case of an emergency — regularly using the feature is not practical or convenient.

Yes and no. Using Wireless PowerShare generates a lot of estrus, which causes wearable to a device's battery. This means if y'all use it regularly, it could exist bad for the lifespan of your phone's battery over a long time. Additionally, the unproportionate battery drain means it is non a practical feature that yous can use daily to accuse your smartwatch, wireless earbuds, or telephone.

Nonetheless, using it once in a while to summit up the bombardment of your earbuds or smartwatch when you are traveling or in an emergency is not going to exist a cause of business organization.

Wireless PowerShare is a valuable feature to have as it allows you to top up your Bluetooth accessories using your Milky way phone easily.

However, the limited power output and the unproportionate battery drain hateful the characteristic is not ideal for charging smartphones or other devices with a large bombardment.
