One of the most convenient features on modern phones is reverse wireless charging. That way you can wireless charge other devices, such as earbuds cases or every other phone, if there’s no other power source available. The Google Pixel 9 also has a version of this called Battery Share, but there’s one key difference compared to older Pixel models.
The problem with reverse wireless charging is that all the power you share has to come out of your phone’s battery. Which isn’t always ideal. Older Pixels allowed you to mitigate this problem by letting you share power while your phone was plugged in. Which was good if you had a USB-C charger but needed to charge a device that didn’t support it. Like an iPhone, or a wearable. But that’s no longer possible with the Pixel 9.
