After almost two years of launching Snapdragon Wear 310, Qualcomm has announced the Snapdragon Wear 4100 series of chipsets for wearable devices. This new chipset series includes the Snapdragon Wear 4100 and 4100+ that are meant to give a performance boost to smartwatches.

The Snapdragon Wear 4100+ comes with a more efficient and smaller 12nm processor compared to 28nm used by its predecessor. Qualcomm says this makes for a “significantly faster new processor.” It also brings a 25% improvement in battery life and there is equally a faster LPDDR3 memory.
The Snapdragon Wear 4100+ includes the main SoC, the Always-On (AON) co-processor for low power states, along with companion chips including PMIC, RF for modem/GPS, and Wi-Fi/Bluetooth, and RFFE. The main SoC features quad-core A53 processors clocked at 1.7GHz for 85% faster performance and the graphics are powered by the Adreno 504 GPU which is 2.5x faster.
The co-processor helps to increase the capabilities of tasks handled by the SoC. This includes offloading sleep tracking and heart-rate tracking to this resource-efficient chip instead of the main CPU, giving the main CPU enough power to handle more tasks.
In addition to that, the new Snapdragon 4100 series comes with an improved “watch mode” that now supports up to 64,000 colors, battery indicators, alarms, reminders, and haptics, while Qualcomm touts “faster tilt-to-wake responsiveness.”
Apart from Wear OS, the Snapdragon Wear 4100 series supports the Android Open Source Platform (AOSP). There is support for up to 16-megapixel cameras. As for the availability, Qualcomm says that the new chipset will be coming soon with the smartwatches.
