Google’s upcoming Pixel Watch 4 is expected to include several improvements over its predecessor. Key features include enhanced blood oxygen tracking capabilities, which will enable the feature to run continuously and alert wearers when their levels are too low. Additionally, the watch may offer emergency satellite communications in cases of distress. Furthermore, it is likely that the watch will support Android 16’s notification cooldown feature, limiting excessive notification spam. While the Pixel Watch 4 is not a major overhaul, these updates demonstrate Google’s commitment to enhancing its wearable devices. The device is set to launch on August 20, according to recent announcements.
