Apple Watch Ultra is found to have nearly double the battery capacity of the Watch Series 8
Apple stands out among mobile tech OEMs in its persistent reluctance to cite exact battery stats for its newest devices, even its Watches. However, Chemtrec has now dispelled this mystery for yet another year with its latest additions to its Product Information Sheet for devices from the Cupertino giant's main brands.
They include initial third-party watt-hour estimates for the entire new Apple Watch series, the inaugural Ultra variant included. The first-gen rugged edition has been found to have nearly double the power of the single vanilla Series 8 SKU tested thus far, at 2.09Wh and 1.19Wh respectively.
Nevertheless, Apple estimates that both the Series 8 and Watch Ultra will last the same amount of time (36 hours) between charges in normal use; maybe all of those extra navigational features take it out of the new top-end wearable. Its users might be advised to take it easy on trying to find out, as an official battery replacement costs US$99.
Finally, the Watch SE has finally been updated in 2022, and it seems to have a battery upgrade, if not much of one: it is now listed by Chemtrec at 1.12Wh, whereas its A235x predecessors were all just under 1Wh.
