Chances are you’ll not have seen, however smartwatches are lastly changing into commonplace. The query being requested has shifted from “Ought to I get a smartwatch?” to “Which smartwatch ought to I get?”. Units just like the Apple Watch have made a wearable laptop a luxurious merchandise and luxurious watch corporations are actually making wearable computer systems. In actual fact, it’s grow to be tough to discover a watch firm that doesn’t now make a smartwatch.

The issue that persists although, is that, aside from a few corporations, smartwatches are nonetheless a bit sluggish, and have lower than stellar battery life. Google’s Wear OS simply hasn’t been given the R&D sources it deserves, and Apple is without doubt one of the solely corporations that makes yearly enhancements to its watch processor, so there hasn’t been a ton of incentive to make smartwatches that significantly better. Qualcomm improved efficiency with the Snapdragon Put on 3100 in 2018, however the battery life on most watches has remained subpar.

However this yr, Qualcomm is trying to deal with most of the issues smartwatches face with the brand new Put on 4100 and Put on 4100 chips. Right here’s what’s new.

A giant little die shrink

The umbrella encompassing a lot of the enhancements within the Put on 4100 sequence is an enormous course of shrink. Whereas the Put on 3100 sequence was primarily based on a 28nm course of, the 4100 sequence strikes straight to a 12nm course of. This leads to a number of enhancements, together with an enormous pace bump and improved battery life.

The CPU on the Put on 4100 has moved from the Cortex A7 to the Cortex A53. Whereas nonetheless quad-core, the clock pace has been massively improved, as much as 1.7GHz from 1.1GHz. Qualcomm says this leads to 85% higher efficiency, which ought to make watches really feel a lot snappier. RAM on the chip additionally will get an 85% pace enhance, now operating at 750MHz, up from 400MHz on the Put on 3100. Lastly, the GPU is upgraded to the Adreno A504 from the Adreno 304, which affords a 2.5x efficiency enhance.

Qualcomm has additionally added a second Image Signal Processor (ISP) to the Put on 4100, permitting smartwatches to function two cameras, up from one on the Put on 3100.

A greater co-processor

The co-processor is one in every of its most vital options. Qualcomm says smartwatches spend 95% of their lifetimes in ambient mode, with solely 5% devoted to lively processing. Due to this, the co-processor must be efficient at ambiently displaying data in a low-power state.

Qualcomm shifted quite a lot of lower-powered actions like step counting, alarms, and haptics to its QCC1110 co-processor, which can sip energy in comparison with the first processor. As a result of most of the interactions now we have with smartwatches are primarily based round these options, the chip can save quite a lot of energy.

Many low-power features are shifting to the co-processor.

That is vital for individuals who use their smartwatches for sleep tracking. If you should cost your watch each evening, you gained’t be capable to use it for these options. With quite a lot of options being moved to the co-processor to function in a low-energy state, this could allow sufficient battery life to make use of options like sleep monitoring.

The co-processor has been enhanced in different methods, like an improved 16-bit shade vary, which might now show as much as 64,000 distinctive tones up from simply 16 on the Put on 3100 sequence. This allows the ambient mode to indicate extra expressive options. An ambient battery indicator will even assist you realize when you should cost your watch.

Put on 4100 vs 4100 Plus: What’s the distinction?

The most important distinction between the 4100 and 4100 Plus platforms is the presence of the co-processor. Clients who go for the 4100 will nonetheless see the efficiency advantages from the die shrink and parts enhancements, however the lack of a co-processor will make ambient mode lower than supreme.

The 4100 will most likely be priced an honest quantity lower than the 4100 Plus, however contemplating the enhancements the co-processor brings, it’s possible most ODMs will attain for the 4100 Plus as a rule. Qualcomm says prospects might select the 4100 over the 4100 Plus if they’re making less complicated watches for teenagers or seniors, or in the event that they need to use their very own co-processor.

When will we begin seeing units?

Up to now, two ODMs have dedicated to utilizing Qualcomm’s new platform. Mobvoi will it for a new TicWatch, the TicWatch Professional 3, and Xiaotiancai, a BBK model, will use the platform for a brand new youngsters smartwatch which takes benefit of the brand new second ISP to supply two cameras. The brand new TicWatch will probably be launching by the top of the yr, and the Xiaotiancai Z6 will launch inside 30 days.

Contemplating the huge leap in efficiency and the improved battery life, we’re hoping to see a variety of new units with the brand new platform quickly.
