"Design Challenges and Compatibility Issues: Exploring the Google Pixel Watch 2"

The switch from a smooth puck charger to pogo pins in the new Pixel Watch 2 highlights the design challenges faced by smartwatches and wearables. The addition of a new multipath sensor in the watch necessitated the change, as it left less room for charging elements. Wearable devices are often too small for USB-C connectors, and the design of smartwatches limits charging areas to the bottom perimeter or sides of the device. While pins allow for faster charging, they can corrode or snap off over time. Proprietary chargers and cases are common in the wearable industry due to the unique design requirements of each device. Despite the drawbacks, Google believes the benefits of the new sensor array and refined design outweigh the cons.
