Apple Watch Series 10 vs 9 and earlier: What’s new and improved?

Apple Watch Series 10 is here and comes with the largest screen ever paired with the thinnest design, a new chip, faster charging, and new health/fitness features. Join along for an in-depth look at what’s new and improved with Apple Watch 10 vs 9 and earlier.

Apple Watch Series 10 vs 9 and earlier

Processor, GPU, Neural Engine, storage

Series 10 is powered by the new S10 SiP. Apple didn’t share any details on exactly how much faster it is compared to S9 and earlier. But it says it was custom-designed for “performance, power efficiency, and intelligence.”

During its unveiling, Apple suggested the S10 will deliver better experiences with machine learning tasks, on-device Siri, health features, and capabilities like Apple Watch double tap control.

If you’re coming from Series 9 you might not notice much of a difference in speed and capability, but if you have an older model you likely will.

Two more benefits, compared to Apple Watch 8 or earlier, you get an increase in storage to 64GB and the ultra wideband gen 2 chip with Series 10 which offers precision finding.

Case and display

Apple Watch Series 10 introduces new sizes for the wearable that feature the biggest displays and thinnest design.

The 46 and 42mm cases offer what Apple says is up to 30% more screen area compared to Series 6. That means you get an additional line of text on the display and for the 46mm Series 10, a display that is ever-so-slightly larger than even the 49mm Apple Watch Ultra/2.

Both the display and case of Series 10 have more rounded corners that give a softer and sleeker feel. Interestingly, Apple did increase the bezel of the display slightly with Series 10.

For thickness, Apple says Series 10 is almost 10% thinner than Series 7-9:

Apple Watch band compatibility

Apple highlights “You can match most bands with any Apple Watch Series 3 or later case of the same size.”

Battery life and charging

Apple has improved charging with Series 10. It can go from 0-80% in just 30 minutes. That’s compared to 45 minutes for the same with Series 7-9.

Battery life remains the same at up to 18 hours with standard mode and up to 36 hours with Low Power mode.

I am one of your Canadian readers - blood oxygen app still available in Canada. Where I live in BC plenty of people come up from US to buy apple products especially when the USD is strong (like it is now) so some Americans may have that option if they really want that feature and live near the border or are visiting the country. Other than small regional differences, the Canadian products are same as American

For those with older Apple Watch models, you’ll be getting additional upgrades like an always-on screen, faster charging, and all of Apple’s health features.

The new Sleep apnea notifications will be available with Series 10, 9, and Ultra 2.
