Suunto 9 Peak maximum battery life
-
@babychai if you use navigation, S+ apps, or guides, battery life can be shorter than 25 hours. Battery life is also reduced if you receive many notifications or autolap is very frequent (the screen lights up). I consistently have an estimated battery life between 24 and 30 hours (measured after activity).
I even plotted estimated battery life over the past year for the S9P (and other watches) and found consistent results.Watch: Suunto Vertical Ti

The main item anyhow is GPS systems. Using Galileo or Glonass alone immediately reduces battery life (even the expected one shown by the watch) to 21 hours instead of 25.
Also, hiking - because you go slow and therefore GPS reception is more difficult, leaving along the possibility of being in the woods or other difficult conditions - tends to have slighly lower battery life than e.g. running.Considering batetry consumption is not entirely linear (i.e. you cannot take the first hours of consumption and think that the consumption rate will be the same for the remaining 20 hours), 16% in three hours is essentially in line with what I would expect if Galileo or Glonass were in use.
Also, of course, notifications and backlight are a great point. If checking the watch often is not that important, using the “display timeout” battery saving feature will definitely increase battery life significantly

@egika I don’t think there’s an official statement. And I might be wrong of course, I think I either read it in the forum, or saw in a video. Don’t have s9p myself.

The official battery life of 25 hours is with Glonass, not with GPS only.

@isazi I was actually using the 9 Baro stats, thanks for pointing that out; it’s true that the 9 Peak actually (when using OHR) has longer battery life than the 9 and 9 Baro.
Glonass and Galileo do use more battery compared to not using them, but the official (and exepcted, in fact) battery life is still 25 with them on so I was wrong. -
@spree indeed for the 9B 24/25 hours is with GPS only. The 9P with GPS only gets closer to 29/30.

@isazi Ah i see. i did turn on S+ Features
Although my notification is turned on but i did not receive any notification because i already turned off my mobile phone Bluetooth.Besides that, I also use setting below for my 3 hours hike:
Autolap: Off
GPS System: GPS+QZSS+GLONASS
Backlight: Off
Brightness: Medium
Standby: Off
Raise to wake: OffSince battery consumption is not linear, next time i will try again for the longer hike.
Thanks everyone for the reply and provide very useful informations.

Is there any way to turn on “display timeout” without using Custom setting threre?

@babychai No, you must set up a custom battery setting to use display timeout.

@brad_olwin Alright, got it. thanks.

@babychai
Hi can you set a custom battery mode on the Peak 9? The manual says you can but I read somewhere else that you can only do it on the 9 and I can’t see an option in the app. Thanks! -

@loopylou72 I can confirm that this is possible. Same options as for the S9B.
Custom battery mode is set in the watch. Not in the app. -

yep I replied to the wrong person but couldn’t delete my first comment as I am a ‘new user’ -
@surfboomerang thanks I found it

@loopylou72 Sorry, I was out using my Suunto and had no internet access for a couple days.

@Brad_Olwin looks nice! My watch died on my 30hr run. I had changed the settings but still had the best GPS. For future reference, if using the ‘good’ GPS what is the impact of this on distance/pace accuracy?
-
@loopylou72 are you using Best GPS to achieve 30 hours? What is your watch settings?
-
@babychai
Yes best gps
Screen saver on
Screen brightness low
I had turned autolap off but in the race it was on, I think because I changed the settings in the normal battery mode and later switched to manual battery to enable the screen saver/screen time-out not realising this would affect the general settings I’d set up so this may have drained more battery… the watch suggested switching to endurance mode as it ran low but still died. If I’d just used endurance mode I was worried it would affect my other data ie pace, distance, elevation?
