The main critiques of WearOS devices are they’re slow and have poor battery life. The OS didn’t help in the early days – it was a bloated system based on the smartphone version of Android – but it’s gone on a diet in recent years. What has continued to hold WearOS back is the lack of a decent processor.
Chipset maker Qualcomm has understandably focused its resources on making stellar processors for smartphones. With Apple and Samsung dominating the wearable market, and manufacturers abandoning Google’s platform, a wearable chipset just wasn’t Qualcomm’s priority.
Smartphone sales have slumped dramatically in recent years. It’s likely there will be some uptick as people upgrade to 5G, but the smartphone boom is pretty much over. Qualcomm will be looking for new sources of revenue.
While Apple and Samsung are dominating the wearable market, it’s still a relatively small market overall. Most people now have smartphones in their pockets but the vast majority don’t have a smartwatch on their wrists.
Qualcomm surprised us with two new WearOS processors this week, the Snapdragon Wear 4100 and the Snapdragon Wear 4100+.
The last WearOS processor from Qualcomm was the Wear 3100 in 2018. The 3100 was a minor upgrade to the 2100 which debuted in 2016 (in fact, they even use the same main processor.)
The processor in the 3100 and 2100 was based on the archaic 28nm process. The 4100, however, gets with the times and jumps to a 12nm process which Qualcomm says will provide around 25 percent battery life.
Elsewhere, we’re getting four A53 CPU cores in the 4100 clocked at 1.7GHz – replacing the 3100’s A7 cores, which ran at just 1.1GHz. Qualcomm is estimating the 4100 will provide more than 85 percent faster performance than the 3100 on the CPU side. The new Adreno A504 GPU, meanwhile, will be up to two and a half times faster than the Adreno A304 in the previous chipset.
As for the 4100+, the difference is the inclusion of a co-processor which is typically used for the “Watch Mode” on many smartwatches to increase battery life by limiting features. The QCC1110 co-processor in the 4100+ can now display up to 64,000 colors (up from the 16 colors that the 3100 could show) in addition to supporting features like step tracking, continuous heart-rate tracking, and more which previously relied on the main processor.
Long story short, this is the first decent processor available for Wear OS
There would have been little point in Google releasing a Pixel Watch before now when it wouldn’t have been able to provide any better performance than existing Wear OS smartwatches. Now the Wear 4100 is available, it’s a very different story.
Qualcomm has said it’s already shipping the 4100 to device manufacturers. TicWatch maker Mobvoi has confirmed it’s making a new smartwatch featuring the new chips. All eyes, however, are on Google.
Google purchased Fitbit for $2.1 billion earlier this year – a small sum for Google, but still not the kind of money you’d splash on a wearable maker if you have no interest in, know, making wearable.
You’ve got the Pixel Watch, Pixel smartphone, Pixel Buds, Pixel book… there’s a smartwatch-shaped hole in that lineup. I wouldn’t be surprised to see it filled in the coming months.
