Apple has introduced a nice little software update for the Watch Ultra to ensure you keep that precious battery.
Those with the bulky but adventurous device can now go into Low Power mode while doing a workout.
The Watch Ultra already had the longest battery life out of any previous edition.
However, the tech geniuses at Apple decided to up the ante by including this new mode in the latest software update.
A statement from the company said: "With the Low Power Mode in Workout settings, most athletes have enough battery life to complete a long-distance triathlon—which includes a 2.4-mile swim, a 112-mile bicycle race, and a marathon.
"And to take it even further, watchOS 9.1 introduces a new option in Workout settings for walking, running, and hiking workouts that allow for fewer GPS and heart rate readings.
"When these settings are enabled, Apple Watch Ultra can achieve up to 60 hours on a single charge, including 15 hours of a Hiking workout—perfect for a weekend adventure."
That is a hell of a lot of time staying active without worrying about your battery life.
Apple says this new update is possible by reducing the number of times the watch will read your GPS location and heart rate.
In the Low Power Mode Workout, the Ultra will take one GPS measurement every two minutes instead of one every second.
"In order to maintain accurate distances, Apple developed several new algorithms to fill in the gaps," Apple said in a statement.
"If you are walking or hiking along known trails or roads that the watch has data for, Ultra computes the distance along the trail, so you’ll get credit for all of the turns and switchbacks you take between GPS measurements.
"This is only done if Apple is confident that you are following the trail."
The Ultra will use data from the accelerometer and gyroscope with Apple Maps’ knowledge of terrain steepness and GPS measurements if you end up on a trail that's a little off-piste.
