More smartphones these days are arriving with support for reverse wireless charging. What this means is that users will be able to use their own phones to wirelessly charge another device that supports wireless charging, like another smartphone or a case for their wireless earbuds, which is a pretty useful feature to have.
However, the problem is that most of the time, users will need to manually enable the feature which can be a bit inconvenient and troublesome if you use the feature frequently. However, according to 9to5Google, they spotted a support document for the Google Pixel 5 which revealed that the handset actually automatically turns on reverse wireless charging when it’s plugged into a charger.
This feature, known as Battery Share, will turn itself on when it detects that the Pixel 5 is being charged, and is also smart enough to know when the feature isn’t being used and after a short period of time when it senses that the power isn’t being used, it will turn it off. This means that users can plug in their Pixel 5 phone to charge and immediately take advantage of the reverse wireless charging feature without having to fiddle with their settings.
That being said, reverse wireless charging is pretty terrible in its current state where the charge is a mere trickle compared to using a dedicated wireless charger or wired charging, but it can come in handy in a pinch.
