I got my Pebble Time 2 recently and i’m loving it so far. I’ve noticed the heart rate monitor uses about 25% of the battery according to the app’s metrics.
I would love a feature to schedule when it’s active so I don’t have to go into the app and disable health features manually. As someone who can’t use electronic devices at work, at least not in all areas of my work, I’d like to have a feature where I can schedule the heartrate monitor to be disabled certain days of the week for certain periods of time. I’ve also noticed the monitor will still try to read my heartrate regularly even when the watch isn’t on my wrist.
For example, disabling the heartrate monitor during my typical work hours, and then turning back on after my shift. This would still let it track steps walking around, but wouldn’t needlessly try reading my heartrate while the watch is sitting outside device-free areas.

Do you have the “HR during activities” enabled? I have that disabled and frequency set to 10 minutes, and battery usage is usually in the single digits.
I have “HR during activities” disabled. I probably didn’t do a great job communicating my idea, I’m not always great with explaining my position.
I have the HR monitor set to sample every 30 minutes currently, and looking at the watch battery stats in the app, it’s reporting that about 26% of the battery drain is coming from the HR monitor. This is over a period of 11 days, with about 5 remaining until empty (2 weeks or so on a full charge)
I work four 10 hour shifts, with about an hour commute both ways, so disabling the HR monitor while I’m at work would save 26% battery drain 12h a day for four days a week. Some rough math says I’d save ~7.4% battery/week which would equate to a couple extra days of battery life. I could be way off on this math, but the calculation is below if it’s useful to anyone.
It would just be more convenient to have an option in the app to turn the HR monitor on or off automatically then to do so by hand.
Bad math:
12h/day for 4days / week = 28% of the time
26% battery drain from the HR monitor
0.28 weeks * 0.26 battery load = 0.074
