Apple Watch Ultra 3 vs Apple Watch Series 11 battery life
As we mentioned earlier, one of the huge selling points of the Apple Watch Ultra series is that it has a longer battery life. While this caters to people who might be taking part in extreme sports, such as ultramarathons, Hyrox and 24-hour Tough Mudder races, it’s also an advantage not to have to remember to charge your smartwatch every night.
The Apple Watch Series 11 will maintain up to 24 hours of battery life on a single charge, whereas the Apple Watch Ultra 3 will offer up to 36 hours on a single charge.
Faster charging technology, which we first saw on the Apple Watch Series 10, and which is brilliant for people who rely on their smartwatch throughout the day and night, will be incorporated on both smartwatches.
Apple Watch Ultra 3 vs Apple Watch Series 11 display size
While the Apple Watch display size is significantly smaller than that of an iPhone, as users, we still want to be able to see notifications and updates at the tilt of our head, which is why smartwatch users were eager to see a larger display size on the new Apple Watch offerings.
The Apple Watch Ultra 3 has certainly delivered in the display department! The Apple Watch Ultra 3 has an OLED screen and 422 x 514 pixel resolution, higher than the Apple Watch Ultra 2’s 410 x 502 pixel resolution, and the bezel width has been trimmed to expand the display size, meaning that the dimensions still come in at 49mm in height and 44mm in width.
Also on the Apple Watch Ultra 3, the smartwatch comes with an upgraded LTPO3 display, which allows the smartwatch display to dynamically switch between refresh rates (the number of times per second a display updates with a new image), making for a smoother experience.
The new Apple Watch Ultra 3 has a maximum brightness of 4,000 nits, in comparison, the Apple Watch Series 11 has a maximum brightness of 3,000 nits.
Plus, the Apple Watch Series 11 will maintain the same sizing as the Apple Watch Series 10: 46mm in height and 42mm in width.
As we saw on the Apple iPhone 17 line-up, the Apple Watch Series 11 display will include Liquid Glass Flow.
Apple Watch Ultra 3 vs Apple Watch Series 11 health features
Both the Apple Watch Ultra 3 and Apple Watch Series 11 feature the new S11 chip, which comes with a dual-core CPU and 64GB of storage, allowing for faster processing speeds and plenty of space for apps and storing data. The new chipset makes the fantastic health and fitness features possible.
At its core, the Apple Watch helps you keep an eye on your health, and one of the more exciting new health features includes high blood pressure alerts, which alerts to any possible hypertension. Similar to the sleep apnea detection feature, the high blood pressure alert will provide users with early warnings for the condition. Apple expects the Apple Watch to help alert up to one million people about possible hypertension within the first year of wearing an Apple Watch.
Plus, Apple has reintroduced the blood oxygen tracking feature to the Apple Watch Ultra 3 and Apple Watch Series 11.
Apple Watch Ultra 3 vs Apple Watch Series 11 fitness features
Apple has transitioned to a MediaTek processor, which enables powerful performance without compromising on efficient energy use. The Apple Watch Ultra 3 and Apple Watch Series 11 also offer a more reliable network performance, too.
Satellite connectivity has been introduced to the Apple Watch Ultra 3, which is brilliant for fitness fanatics who exercise in remote or off-grid locations. As for location tracking, ultra-wideband technology ensures precision.
Our verdict: why we’d recommend the new Apple Watch Ultra 3
Battery life is a critical factor for smartwatch users; with smartwatches continually tracking your health, fitness, and keeping you up to date with your notifications such as iMessages, the last thing anyone wants is their smartwatch running out of battery mid-day.
As we mentioned earlier, the Apple Watch Ultra 3 boasts a 36-hour battery life on a single charge, which is not only fantastic for extreme sports like ultramarathons, but it’s also brilliant for less intense situations, such as someone travelling across the country, a shift worker wanting to track their steps, and for last-minute sleepovers where you’d still like to monitor your sleep patterns.
As well as battery life, the Apple Watch Ultra 3 delivers with its larger and brighter display. If you rely on your smartwatch for detailed visuals, such as health data, you’ll love the new LTPO3 display which offers improved resolution and great power efficiency. Plus, the Apple Watch Ultra will debut with exclusive watch faces.
