Is It Worth Upgrading?

The Apple Watch Series 10 brings several enhancements over the Series 9, but for most users, the differences are incremental. The thinner and lighter design is an improvement, but it doesn't fundamentally alter the device's overall appearance or experience. The slightly larger display and wide-angle OLED, while improving readability, isn't a drastic change.

The improved speaker and microphone on the Series 10 are also worth noting as minor upgrades. The new speaker can playback media for the first time and the microphone now features voice isolation, improving call clarity in noisy environments.

One of the more significant changes is the faster charging. The Series 10 charges to 80% in around 30 minutes, compared to 45 minutes for the Series 9, which could be a noteworthy improvement for users who frequently need quick charges. Additionally, the Series 10 introduces new finishes, including a polished Jet Black aluminum and polished titanium options, offering a more premium aesthetic.

While the Series 10 does bring some useful upgrades, like water depth and temperature sensing, faster charging and improved audio quality, most of these enhancements feel like refinements rather than essential upgrades. Unless you're particularly drawn to the refreshed design and display improvements, the faster charging, new water features, or the speaker and microphone improvements, it's hard to justify upgrading from the Series 9. For most users, the differences won't significantly impact their daily use, making the Series 10 an upgrade only for those with very specific needs or preferences.

Those with a much older Apple Watch will have much better reason to upgrade, with the improvements of successive Apple Watch generations, such as body temperature sensing and the Double Tap gesture, stacking up for a more substantial overall difference.
