Huge Battery drain vs 935

Hi all. I'm coming from a 935 and I was extremely happy with battery. Now, with 945,the battery last almost half of the time vs 935,maybe even less than half. What could be the reason? The pulsimeter always on? Any other reason? anyone have some comments?

Does a hard reset wipe all the settings? And how do you perform it exactly?

yes pulse ox will drain the battery, as Garmin point out. Get the latest firmware and turn off backlight until sunset also helps massively.
