      battery life in activity is independent from the daily basic settings like 24/7 HR, notifications etc… of course if you receive frequent calls during a hike (hopefully not), then it wears down the battery.
      there are few things you can do:
      turn off backlight (small impact IMHO)
      turn off auto laps
      use the GPS settings with only few different systems (GPS and QZSS afair)
      and last but not least, use an external HR sensor over the internal OHR if you have one or don’t mind buying one.
      at least in my S9B I’ve got 32h instead of 25h predicted battery life.
      Never tested if it really gets to these amount of hours since I usually don’t have so long consecutive hikes.
      And my S9B battery testings are over 2.5 years back, so I don’t remember anymore the consumption per hour that I could calculate linearly.

      what you can also do is taking a power bank with you and charge while hiking?

      and last but not least: maybe it’s just a momentary issue. Similar to S9B in the beginning.

        @freeheeler If I recall correctly s9p has actually better battery life with Ohr than with a belt.

        Regarding battery consumption: I think battery consumption is not linear, maybe try testing it for a longer hike to deplete a third or even a half of the battery charge, this might be more representative.

          oh, true! sorry for my misleading comment… and thank you for correcting me!
          in S9B it’s the other way around.
          OHR must have become more efficient 👍

            @dmytro not sure about this one.
            It is true for S7 - S9(B/P) series has super low power BT…
            Is there an official statement about this somewhere?

            t6, S6, Elementum Terra, Ambit 3 Sapphire, Spartan Ultra Copper, Traverse Alpha, S7 Graphite LE, S9B Ambassador, S9P Granite Blue Titanium, S9PP Titanium Sand, Vertical All Black, Race Titanium Charcoal,

              @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.

                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: Off

                          Since 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.

                                  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.
