· Leave a Comment

You can use Galaxy S10 wireless PowerShare to charge other devices wirelessly.

Galaxy S10 (including Galaxy S10, S10+, S10e, and S10 5G) can be used as a wireless charger to share Galaxy S10 battery with other devices.

This  Galaxy S10 new feature guide explains the details of Galaxy S10 wireless PowerShare feature, how to use it to charge other devices, and answers some questions you may have when using the wireless PowerShare.

What is Galaxy S10 wireless PowerShare?

Wireless charging is not new. Samsung added it as a standard feature since Galaxy S6.

But using the phone as a wireless charger to share the phone battery with other devices is still new.

Huawei named this feature as wireless reverse charging and introduced it in Mate 20 Pro (in 2018) and P30 Pro. Samsung introduced this feature in Galaxy S10 (all 4 models) and named it as wireless PowerShare.

Galaxy S10 wireless PowerShare lets you share the battery juice of Galaxy S1o with other devices that support Qi wireless charging.

Technically, you can still use Galaxy S10 as usual when you share the battery with other devices.

You can even use wireless PowerShare when you are charging Galaxy S10 battery through a USB cable.  For example, you may have only one charger, but you need to charge both the phone and a Galaxy Watch.  In this case, you can connect the wall charger to charge Galaxy S10 and use wireless PowerShare to charge the watch.

In a nutshell, Galaxy S10 wireless PowerShare adds a Qi wireless charger on the back of Galaxy S10. And the charger can use Galaxy S10 battery to charge other devices wirelessly.

Limitations of Galaxy S10 wireless PowerShare

Wireless PowerShare is very convenient, and it works with any devices that support Qi wireless charging.

FYI, most recent mobile devices including iPhone support Qi wireless charging. All Samsung gadgets with wireless charging support Qi wireless.

But wireless PowerShare on Galaxy S10 has some limitations including:

  • Charging speed is slow. There is no fast charging. The maximum charging capacity is 5W. The actual charging speed is substantially lower than this. So, Galaxy S10 wireless PowerShare is mainly designed for accessories like Galaxy Buds, Galaxy Watch. It may be a temporal solution of sharing the battery with other phones. If the other phone also has a USB C port,  you can charge it faster by directly connecting Galaxy S10 to that phone with a USB-C to USB-C cable.
  • You may have to remove the covers or cases for Galaxy S10.  When you charge Galaxy S10 with a wireless charging pad, normally it is not necessary to remove the cover unless the cover is exceptionally thick (or is made of metal). At least, for all Samsung Galaxy S10 official cases (for example, Galaxy S10 LED back cover, Galaxy S10 LED view cover, and Galaxy S10 clear view cover). But when you use wireless PowerShare, you very likely

  • Mood lighting.  When Galaxy S10 is facing downwards, a light show is presented with the LEDs.  You can only enable or disable the show, not customize the show.
  • LED notification icons. You will get notification icons on the back when a notification comes. But the LED notification icon only works with some Samsung apps, and you cannot customize the LED icons (as in Galaxy S10 LED View cover).

You need to charge Galaxy S10 battery properly to maximize the battery life without sacrificing your usage.

There are many so-called expert recommendations and rules on how to charge Galaxy S10 battery. Some of them are outdated (e.g., you need to drain Galaxy S10 battery completely every a few weeks). Some are ridiculously wrong (e.g., you should not charge Galaxy S10 battery to full).

This Galaxy S10 how-to guide explains the proper way to charge Galaxy S10 battery with a wall charger (USB charging) or a wireless charger (wireless charging). Quick charge 2.0 and fast wireless charging 2.0 are also discussed.

How long should I charge Galaxy S10 battery the first time?

The old textbook may tell you that you should charge the new battery for at least 6-8 hours for the first time.

This is outdated. It does not apply to the Galaxy S10 battery.

When you charge Galaxy S10 battery the first time, you just need to charge it to “charged.” Then you can disconnect it from the charger (wall charger or wireless charger) and start to use it.

In fact, when Galaxy S10 leaves the factory, the battery was charged to about 60%. You can immediately use the phone when you get it. It is unnecessary to charge a new Galaxy S10 for 6 hours.

In some regions, Samsung does not offer a 1-to-1 exchange for hardware defects. You have to check the phone in the store.

Anyway, there are no special requirements when you charge Galaxy S10 battery the first time.

Please note, there is no notification LED in Galaxy S10 (including S10, S10+, S10e, and S10 5G) as discussed in this page, you have to wake up the screen to check whether the battery is fully charged or not.
