Google preps Fast Pair low-battery notifications for styles

Since its launch, Fast Pair has grown beyond Bluetooth headphones to smartwatches and Matter smart home devices. Fast Pair’s next device category looks to be the stylus ahead of the Pixel Tablet.

About APK Insight: In this “APK Insight” post, we’ve decompiled the latest version of an application that Google uploaded to the Play Store. When we decompile these files (called APKs, in the case of Android apps), we’re able to see various lines of code within that hint at possible future features. Keep in mind that Google may or may not ever ship these features, and our interpretation of what they are may be imperfect. We’ll try to enable those that are closer to being finished, however, to show you how they’ll look in case that they do ship. With that in mind, read on.


The Pixel Tablet will support USI styluses, and just this week Android 13 QPR2 Beta 2 included some details about stylus charging notifications.

Google Play services (for Wear OS, version 23.02.13) has now been updated with a trio of “fast_pair_stylus” strings for low-battery notifications that are similar to what you’d get with Bluetooth headphones.

It makes sense for Google to use familiar Fast Pair battery alerts for the stylus category.

Meanwhile, an update to the Settings Services app, which powers the Pixel’s Battery widget, this week added a generic “bt_stylus” icon. There’s nothing more explicit yet, but having the current percentage of a Pixel Tablet stylus appearing in the Battery widget makes sense.

Google will hopefully make a first-party Pixel stylus, pen, or pencil for its upcoming Tablet to offer a good end-to-end experience. It remains to be seen how a hypothetical stylus would charge. A USB-C port on the pen would be highly inelegant, so wireless is the way to go.

From what we’ve seen of the Pixel Tablet so far, there’s no clear charging surface on the side edges, like the iPad Pro. Using the rear pins for the Charging Speaker Dock would be physically awkward, resulting in a slant when connected, while one – purely speculative – option could be that the thicker bezel of the screen hides a charger.
