Apple is expected to unleash a deluge of Apple Watch details at its event on March 9, but this is the Internet, which means waiting is for suckers. A new report by 9to5Mac has revealed a number of new key details about Apple’s wearable, including health and fitness features, apps, and, most importantly, battery life.

It was reported earlier this year that the Apple Watch’s battery wouldn’t be much better than a typical Android Wear device, and 9to5Mac’s newest details further corroborate that suggestion. Sources who have used the device claim the wearable is capable of getting about “5 hours of fairly heavy application usage,” which means it should last users a typical day depending on how hard they push it.

For most people, the Apple Watch will be a vessel that pushes notifications and other at-a-glance information to a user’s wrist—not really enough to have people running to the nearest outlet every few hours. However, 9to5Mac notes that, even though it should last a full day with mixed usage, it will definitely need to be charged nightly, as it won’t have nearly enough juice to last through a second day.

On that note, however, The New York Times has said the device will feature a Power Reserve Mode designed to cut optional services in favor of preserving the battery. 9to5Mac claims Power Reserve Mode can actually be activated at any time (even when battery is 100-percent); once activated, the mode will apparently put iPhone notifications “to an on-demand” level, dim the display, and even put the display to sleep after just a few seconds of inactivity. Basically what you’d expect out of a mode designed to preserve the battery.

There are some other major Apple Watch details revealed in 9to5Mac’s report, so head there to read up on the device’s fitness features, how the wearable handles “glances,” and what it’s like to use the Force Touch technology.

There are a lot of mixed opinions about Apple’s wearable right now, with sides claiming the device will be a success, and others saying it’ll be an epic failure. We’ll reserve judgement until we actually get our hands on the device—we’ll be in attendance next week at Apple’s Spring Forward event. The company’s wearable is going to launch in April, which means we don’t have much longer to wait.
