Suunto 9 delivers an amazing battery life – up to 120 hours with GPS and an intelligent battery life management system with smart reminders to ensure your watch will last just as long as you need it to.

Battery Modes

The Suunto 9 has 4 x battery modes :

  • 25 hours – Performance Mode
  • 50 hours – Endurance Mode
  • 120 Hours – Ultra Mode
  • Custom mode – you choose what’s important and it tells you the expected battery life

The various battery modes affect the duration of the battery by altering the following parameters

  • GPS Accuracy
  • Display Timeout
  • Wrist HR
  • Touch Sensors on/off
  • Brightness
  • Vibration alerts
  • Bluetooth

It is possible to change the battery mode in the middle of an exercise session (press & hold middle right button)

Suunto 9 – Key Features


Suunto have used the “Fused” prefix to describe a more accurate method of measuring a certain parameter by combining GPS data with barometric pressure data (FusedAlti) and internal accelerometers for speed / distance (FusedSpeed).

HOWEVER .. in the case of FusedTrack Suunto have done something frankly amazing. In ULTRA battery mode the GPS is only sampling every minute or even less.

The Suunto 9 uses data from the gyroscope, compass and motion accelerometer to fill in the speed, distance, direction data between the missing GPS co-ordinates. I have seen an amazing review on DC Rainmaker’s site that shows some stunning accuracy comparing a track recorded with FusedTrack to that of a Garmin Forerunner 935 in full 1 second sampling mode.

What does it mean in the real world …

When you set your Garmin to UltraTrac battery mode – the GPS track is made up of straight lines between co-ordinates taken ever 60 seconds or so … If you switched back on yourself between samples this change of direction will be missed and the track will show you went straight from A to B.

With the Suunto 9 and FusedTrack all the “wiggling about” between data points is tracked and saved giving a far more accurate representation of the actual route. Great job Suunto !!

Top Alternatives

Next Model UP

This is the top of the range in Suunto’s ever increasing range of fitness watches.

When I first read the press release I was a little uncertain how the Suunto 9 fitted in with the existing Suunto Spartan range … to be honest, I’m still a little uncertain. Take a look at Suunto’s own COMPARE features – looking at the Suunto Spartan Sport Wrist HR. Spartan Ultra and this model.

There’s so much overlap it’s quite hard to determine any substantial differences. Most of the differences can be found in the GPS & Navigation section.

Next Model DOWN

This is where the confusion starts for me … what is the model BELOW the Suunto 9. It could be the Suunto Spartan Ultra – but their features are just so similar.

Alternative Models?

The product from other brands with the closest functionality to the Spartan Ultra is the Garmin Fenix 5 (also consider the Fenix 3 HR). The Fenix range, like the Suunto 9 and Spartan Ultra are aimed at customers looking for a ROBUST outdoor solution with ABC functionality (Altimeter, Barometer & Compass watches) and multiple sports modes plus training load and recovery analysis

Garmin Fenix 5 – Garmin’s top of the range ABC watch with wrist based HR for outdoor adventure and beyond
Garmin Fenix 3 HR – Garmin ABC watch with wrist based HR for the outdoor adventurer / multisport athlete


Here’s the bottom line – if you’re not partaking in racing or training events over 6 or 8 hours consider the Suunto Spartan Sport Wrist HR (unless you need the weather / barometric features …).

If you are participating in training / race events over 10 hours or events over several days where charging the watch is not an options then consider the Suunto 9 or Spartan Ultra. What makes the Suunto 9 different to the rest of the Suunto and Garmin adventure racing watches is the FusedTrack feature.
