TheWatch Ultrawas already known to have the longest battery life of anyApplewearable, but now it’s been given a significant upgrade.
This is a considerable upgrade on the 36 hours of battery life Apple says theWatch Ultrais capable of during normal use, with all of its functions switched on.
So what’s actually happening here? It’s all to do with the watch’s most battery-intensive features, the heart rate monitor and GPS antenna. These are both used constantly during exercise, so wear down the battery far more quickly than during normal use. To counter this, Apple has introduced a mode that restricts how often the heart rate monitor and GPS antenna are used.
This setting is called ‘Fewer GPS and heart rate readings’ and arrived as part of the watchOS 9.1 software update. It also appears in the latestWatch Series 8andWatch SEtoo, but will have a lesser effect on these watches’ smaller battery life.
With the function enabled, the watch will take a heart rate reading every minute, and use the GPS antenna every two minutes, instead of constantly. This will mean less accurate readings and mapping data, but Apple has created a new algorithm to help compensate for less data being collected.
To achieve the full 60 hours of battery life, Watch Ultra users need to enable Low Power Mode, as well as the new fewer GPS and heart rate readings function. With only Low Power Mode enabled, Apple says the Watch Ultra will last long enough (with constant heart rate readings and GPS) to complete an Ironman race in about 14 to 15 hours.
