Wireless charging has become commonplace with modern-day high-end smartphones. Companies like Apple, Samsung, Huawei, OPPO, and others are now adding support for wireless charging on their premium phones.
On top of wireless charging, there’s also reverse wireless charging, which we have previously delved into deeper. It helps you share your smartphone’s power with another smartphone or even a smart band and smartwatch in basic terms.
If you have a device with reverse wireless charging support and its not working, this guide should help you.
Here are some common ways to troubleshoot wireless reverse charging or wireless power share not working:
Confirm reverse wireless charging support
Before we dive into troubleshooting reverse wireless charging issues, it’s good to start with the basics: support. Does your phone support reverse wireless charging in the first place? If you’re not sure, confirm with the manufacturer’s website for the device’s specific features.
Turn on Wireless PowerShare or Wireless Reverse charging
Are you certain that your phone’s wireless reverse charging is turned on? If not, that might be causing issues. The first step is to ensure that wireless reverse charging is turned on, also known as Wireless PowerShare for those who own Samsung Galaxy phones.
On a Samsung phone with the feature supported, swipe down from the top of the screen with two fingers to access the Quick Settings panel. Then, tap the Wireless PowerShare icon to turn on the feature.
On Huawei phones: Open the Settings app, go to Battery and toggle the Wireless reverse charging switch to turn on.
In other phones, look for similar features and enable them if disabled.
The primary charging device should have enough charge
If the main phone that should provide power doesn’t have sufficient charge, wireless reverse charging won’t work. The battery percentage that is considered sufficient for a device to share its power varies from one smartphone maker to another.
For example, if you have a Samsung Galaxy phone, your device won’t charge another device with less than a 30% charge. For Huawei devices, 20% is the minimum. Below that, wireless reverse charging won’t work.
Remove objects, if any, between the two devices
Wireless reverse charging won’t work if you have an external object between the two devices. Foreign devices could be a third-party protective case, a metal ring, or any other object. That may be the reason why reverse charging is not working.
We mentioned avoiding placing external objects, especially metal ones, between devices in our reverse wireless charging tips. But thick external protective cases and other materials can hinder wireless reverse charging as well.
Bonus tip: Samsung also advises its users to remove headphones while reverse charging as it may affect nearby devices.
Place the device being charged in an appropriate position
Different smartphones have wireless charging coils placed at different locations behind. You’ll need to ensure that the phone being charged is placed on top of wireless charging coils found at the back. Moving the devices slowly can help you find the perfect spot.
Bonus Tip: The position of the devices will affect charging efficiency. The further a device is from the charging coil, the less efficient the process will be and vice versa. Or if out of range, no charging will be done.
There are different wireless charging standards on the market. Qi (pronounced “chee”) is the most common one supported by many manufacturers, including Samsung, Huawei, Sony, HMD’s Nokia, LG, and Apple, developed by the Wireless Power Consortium (WPC). Another standard is called Powermat, but this one is not-so-common.
As long as your device uses the Qi standard, it can charge any device from another manufacturer that also supports it. But compatibility issues shouldn’t be a problem soon as Qi is the only standard on the market after the maker of Powermat pledged to make its alternative compatible with Qi in 2018.
Use another device that supports wireless charging
If all else is good, but your device still doesn’t charge, then try charging another gadget with reverse wireless charging support. You can try to charge another device, maybe your smartwatch or secondary device. If it works, there’s a chance that the device you want to charge is faulty. We advise that you seek help from a certified support team at any of your device’s support centers.
