Apple Watch Ultra: we now know more about its real autonomy

It’s in a big week that the Apple Watch Ultra will land in France. But before its highly anticipated launch, the connected watch gives us new details about its technical specificities.


Today, it is the battery that will interest us. And as we could foresee, notable improvements are to be expected.


A truly premium watch

During its Keynote on September 7, the firm headed by Tim Cook did not just take stock of the iPhone 14 range. A long segment of the conference was indeed devoted to connected watches. So, in addition to a new Apple Watch SE and the Apple Watch Series 8, it was the Apple Watch Ultra that stole the show.


This version with a 49 mm titanium case offers more advanced functionalities in sport and health compared to previous models. It is also much more resistant and prides itself on having exceptional autonomy. And it is precisely this aspect that has just been dug thanks to documents spotted by MySmartPrice.


The stamina of a champion?

When announcing its Apple Watch Ultra, the American multinational mentioned an autonomy of 36 hours with a full charge. This is simply twice as good as that of the Apple Watch Series 8. For this, the engineers chose to use a 542 mAh battery. 76% more capacity than Series 8 45mm (308 mAh). There is even a 92% increase compared to the 41 mm version (282 mAh). But beyond these figures, it is important to understand how Apple measured the autonomy of its latest baby.

Because when the Apple Watch Ultra connects to the LTE network, the battery will logically drain faster. Autonomy will then be halved (18 hours) when the feature is active all day. The famous 36 hours of endurance were measured by counting on eight hours of LTE connection and 28 hours in Bluetooth. In any case, the results obtained are satisfactory… but we will have to judge on the spot when the watch is launched on September 23rd.
