The wearables market is more diverse than it’s ever been, but if there’s one constant, it’s the battle between richer functionality and preserving battery life; one of a number areas Qualcomm’s newly-unveiled Snapdragon W5 Gen 1 and W5 Plus Gen 1 chipsets hope to address.
The two new chips promise huge gains in terms of both performance and functionality, as well as battery life – one of the biggest hurdles makers of even the best smartwatches are constantly struggling to improve.
Qualcomm’s last major wearable chipset release was just over two years ago – in the form of the Snapdragon Wear 4100 platform. Like its predecessor, 2022’s offering also comes in two flavors: the Snapdragon W5 Gen 1 and the W5 Plus Gen 1 (styled as ‘W5+ Gen 1’), which have received a rebrand to complement the company’s latest mobile chipsets; retracting the ‘Wear’ in ‘Snapdragon Wear’ down to simply ‘W’.
Beyond the name, the two models offer a similar gamut of benefits, made possible by the move to a much more refined 4nm process (down from 12nm on the 4100 line). There are a number of other tweaks compared to its predecessor, building on this smaller process makes for a much more efficient chip and that saving gets passed on in the form of better battery life.
Compared to the Snapdragon Wear 4100+, Qualcomm claims that an equivalent Snapdragon W5+ Gen 1-powered smartwatch offers double the battery life, twice the performance and higher fidelity experiences, while also operating on a platform that 30% smaller.
In real-world terms, this means the next wave of smartwatches to use these Qualcomm chips will serve up smoother and more responsive user experiences than the current crop, while going twice as long between charges.
The newly-unveiled Oppo Watch 3 is already confirmed to be relying on a W5 Gen 1, while Mobvoi has committed to employing the new top-tier W5+ Gen 1 in its next smartwatch.
Analysis: should the Apple Watch be worried?
One of the big upgrades that Apple added to the current Apple Watch 7 was fast charging, offering 33% faster charging compared to Apple Watch 6, but the company was already playing catch-up with Qualcomm’s last wearable silicon in that regard, with offerings like Fossil’s Snapdragon Wear 4100 Plus-powered watch boasting its own fast charging that refilled the phone to 80% charge in just 30 minutes.
With the advancements that the W5 line bring to the table, that gap is only getting larger, unless Apple pulls out something particular special in the power efficiency department on the Apple Watch Series 8.
The flip-side is that despite the Qualcomm’s prominent market position, its wearable chips often struggle to find a foothold behind both the Apple Watch and Samsung’s popular Galaxy Watch line.
