Battery drain

sky-runner

And now I am experiencing an extreme battery drain with Race S.

Yesterday while I was at work it entered an extreme power save mode with 3% remaining, but still shut down a couple of hours later. I recharged it to 92% at around 8 pm last night. This morning, 12 hours later, it is already at 53%. No activities in between!

@gkaempfer Thanks. I’m similair. It’s a bizarre result. Congratulations on your watch. Suunto did a great job with yours

I’ve just turned off the SPO2. Can’t imagine that’ll do tricks, but we’ll see. I do use the flashlight. Only a few seconds per day.

@sky-runner That’s really weird. Does it happen often?

My Race S drains possibly a bit quicker, but not by a huge amount. I charged it Monday in the evening and now it is at 74% including about an hour of GPS tracking…

@Horizontal_2 It happened once in the past last year and now was the second time. The rapid discharge has stopped once I’ve recorded an activity - a run.

@sky-runner Do you use an HR belt?

I can say this clearly; I don’t need any extensive testing, I’ve been using Sunto Vertical Titanium Solar for a year and a half. After the last firmware update, I started carrying my charging cable with me. Besides, my sports activities have decreased due to winter, I only use it daily. Now my charging cycle has dropped to once every 6 days.

@safari I agree 100%, we need a fix for this

@safari I’m using a SVTS, backlight, raise to wake and notifications are off. I’m doing around 4 GPS hors per week plus two hours without GPS and i recharge it evry two and a half weeks, if I shut down 24/7 and sleep tracking I get a week more.
So, 6 days it is not normal and not related to the last firmware. Do you have backlight or raise two wacke activated? Do you get hundreds of notifications per day? Did you tried to perform a softreset?

@segi_pn said in Battery drain:

Do you use an HR belt?

Yes, two different external HR sensors connected to the watch - Suunto HR sensor and Coros Armband HR sensor.

And yes, when I had a similar issue in the past it was likely caused by the external HR sensor. But what is interesting and different in this case is that the rapid discharge has happened after the watch battery got fully discharged and the watch turned off, then I charged the batter and didn’t have any activities.
