The Snapdragon Wear 4100+ promises more than 85% faster performance, compared to Snapdragon Wear 3100 platform. Enhanced AON co-processor supports richer offloaded experiences to support up to 64K colours (from 16 colours) and the Ultra-Low Power Platform promises more than 25% power reductions across key use cases and bring extended battery life to the platform (compared to our previous platforms).

The hybrid platform approach brings rich, enhanced experiences across interactive, ambient, sports, and watch modes. In interactive mode, the platform supports additional immersive experiences with camera, voice assistant, and voice/video messaging.

In ambient mode, the increase in number of colors from 16 to 64K and number kerning is designed to make readability crisper and offers more exciting design options.

In sports mode, offloaded maps enhance the on-the-run experience. The traditional watch mode includes features such as heart rate, steps, alarms, reminders, and battery indicator, with minimal impact on performance or battery life.

The Snapdragon Wear 4100 platforms come in two variants: The Snapdragon Wear 4100+ platform which includes the main SOC (SDM429w or SDA429w) and the AON Co-Processor (QCC1110), along with the companion chips including PMIC, RF for Modem/GPS and WiFi/BT, and RFFE and the Snapdragon Wear 4100 platform which comprises of the main SOC along with the companion chips. The Snapdragon Wear 4100 platforms support both the Android Open Source Platform (AOSP) and the Wear OS by Google OS platform. Snapdragon Wear 4100+ and Snapdragon Wear 4100 are available and shipping now.

imoo, leading brand for kid smartwatches will be announcing its next generation Z6 Ultra smartwatch based on the Snapdragon Wear 4100 that will start shipping over the next 30 days. Mobvoi Inc. will be announcing its next generation Tic Watch Pro smartwatches based on the Snapdragon Wear 4100 platform soon.
