Qualcomm launches Snapdragon Wear 3100 smartwatch platform, offering up to 30 day battery life


Qualcomm has launched its all-new Snapdragon wearable platform, Snapdragon Wear 3100.

Although based on the existing 28nm design used in existing watches using Snapdragon Wear 2100, the new ‘killer app’ feature is an ultra-low co-processor that can extend battery life to as high as 30 days, although the actual gains will depend on how individual watch makers decide to utilise the new chip in their own products.

The chipset will be based on a Big.Little.Tiny concept.

As is common for Qualcomm launching a new chipset, it has created its own reference design watch that it showed off to select journalists at an event held in London last month.

I went along to see the pre-briefing and have to say that I was quite impressed with the possibilities, but also left a little disappointed at how the key battery saving features may not be quite as exceptional as suggested given the way you toggle between modes.

In effect, the watch comes with two independent operating systems. In the traditional mode, akin to existing watches running on Snapdragon Wear 2100 platform, the watch will run on Wear OS and operate exactly as other watches do today. While there may be some gains in power management, the real benefits come when you select the power saving mode.

Here you will ‘drop’ to a custom OS that powers a simple always-on display (which can be updated in real-time to provide counting seconds, or a sweeping second hand) and has limited functionality. Unlike hybrid-display watches, the two power states use the same display.

Qualcomm says manufacturers could use an OLED display or a reflective e-paper display as they see fit.

The event-driven RTOS could potentially run on its own on a watch, and Qualcomm was even asked about how this ultra-low power co-processor could perhaps find its way into smartphones to offer exceptional standby life.

However, executives remained tight-lipped and preferred to simply tease us by saying they wouldn’t be talking about that today.

The watch also supports improved NFC and a modem that will work on 130 networks around the world, including more power efficient modems so 4G-enabled watches should consume less power than existing connected watches on sale today.

Choose one or the other

Switching modes would appear to require user intervention, rather than the watch automatically doing so when you’re not actively using the watch. It will not be as simple or quick as the current ambient mode that kicks in after a few seconds – and switching modes takes a short time, meaning you need to make an active decision on how you want the watch to function.

However, hardware manufacturers may opt to do things differently as time goes on. I would certainly like to see a watch that could change at timed intervals, or perhaps even do so when you’re actively engaged with your phone and don’t need to use your watch.

In reality, the time you engage with a smartwatch is relatively small in comparison to your primary device.

Indeed, there’s perhaps no reason that a watch couldn’t be created to only operate with the custom OS and provide the improved battery life gains that will put it on a par with other watches such as the Amazfit Bip.

Qualcomm wouldn’t name individual manufacturers intending to use the new platform for making watches, but did hint that in addition to the current manufacturers that will clearly use it for new watches going forward, there would likely be a number of new entrants to the market, mostly in the high-end fashion space.

At least one watch will be announced for release this year.

Improvements in functionality for sports watches with heart rate monitors and GPS will also likely see a barrage of new active watches hitting the market in 2019.

Down with the kids

Qualcomm also has another platform that was announced earlier in the year, aimed at 4G Kids watches. The Snapdragon Wear 2500 platform will see the global introduction of watches for children, which have traditionally only been popular in certain markets (such as China).

Huawei is one of the first manufacturers to produce a watch for kids, with many more in the pipeline. Last month Vodafone launched a kids watch in the UK, for a one-time payment of £135 and a fixed-monthly fee of £4 to allow the watch to send its location automatically, and allow a child to contact a parent. However, this watch is based on an older platform and newer watches, such as the Huawei one mentioned above, are likely to hit the market soon.

Original press release

SAN FRANCISCO – September 10, 2018 – Today, Qualcomm Technologies, Inc. a subsidiary of Qualcomm Incorporated, launched the next generation Qualcomm® Snapdragon WearTM 3100 Platform for smartwatches. The platform is based on a new ultra-low power system architecture designed to deliver a rich interactive mode, new personalized experiences, and extended battery life. The official launch, at an event in San Francisco, was supported by Google, who discussed the evolution of the Wear OS by Google software platform. The launch also included the announcement of the first Snapdragon Wear 3100 customers.

Snapdragon Wear 3100 Platform Redefines the System Architecture

Snapdragon Wear 3100 is based on a new ultra-low power hierarchical system architecture approach.
