Battery drain

[Horizontal_2]

Hi!

Many are having issues with their battery drain. I’m making this post to use it as a work around your watch. A hard reset every day isn’t what you want.

Main question: What is causing the battery drain and how do you cope?

I think the models that are affected are mainly Vertical 1, Vertical 2 and Race 2. But all other watches are welcome.

You can share your experience. Details matter. Sorry for the lack of my details below. Try to avoid big discussions, which could make the thread less readable, but you can ask for more details and give tips, of course.

Special thanks to @segi_pn who made many charts as well, which is encouraging to make this post.

I logged on of my cycles (14th - 28th of november).

I haven’t got much time to analyse.

Vertical 2 - Titanium
Settings:

• Raise to wake - display only
• Brightness - low
• notifications off
• Airplane mode on and off

A few observations:

• Most of the times my vertical 2 gets it’s 5% per day
• Soft reset doens’t help always. Tried it many times when after my first run the battery kept draining. That’s why I tried the Airplane Mode.
• Airplane Mode does always help, and it’s amazing. I get 3,7% per day. But you should think about the next things: turn it on for a longer period (I used at least 6 hours), toggeling doesn’t work. And turn it on and off in the settings, not via control panel). So here is a feature request: update only a few times per day.
• No use of a HR-belt helps! But I think it’s a big miss. It doesn’t work always. It seems like there could be a drain after a run without HR-belt (H10)

I am attaching my observations and measurements.
I have already completed two cycles from 100% charge to the next charge.

In the first cycle, there was an interesting break in consumption after the first recording of activity with the Suunto Smart HR Belt (I later bought a new chest strap).

In the second cycle, the exact opposite phenomenon occurred: after a sharp discharge, a change occurred and the discharge slowed down.

In addition to the soft reset, I removed the old paired HR belt at that time, as during one activity, the connection with the new HR belt did not start up.

I would like to add that before the last update (2.48.16), when using the watch a little more, I charged it after 10 days when the battery level was slightly above 30%.
Otherwise, I didn’t change my usage. I had continuous heat measurement, sleep tracking, smartphone notifications, brightness = medium, and Raise to wake = Low turned on.
