Start with Performance when its estimated battery life comfortably covers your activity. Consider another mode when you need more duration, but read what it changes before starting. On Suunto Race, Tour disables wrist and chest-strap heart-rate tracking by default, so it is the wrong default choice for a session where heart-rate data matters.
Make the decision on the start screen
Suunto Race offers Performance, Endurance, Ultra and Tour modes. Its exercise start screen estimates remaining recording time, and the Battery mode menu explains the performance changes. Suunto also warns that switching modes changes more than duration.
Our recommendation is to compare that estimate with the whole session you plan to record, including likely delays. Do not plan to finish at the exact estimated limit. An estimate helps choose settings; it does not guarantee your watch will last until a particular time.
| Your priority | Starting decision |
|---|---|
| A session comfortably within the Performance estimate | Keep Performance |
| A long activity that exceeds the current estimate | Compare the other modes and accept only trade-offs that suit the session |
| Heart-rate data throughout the activity | Avoid Tour's default configuration |
| Longer life between workouts, rather than during one | Look at everyday Power saving separately |

Power saving is a different setting
The watch's everyday Power saving setting turns off vibration, daily heart-rate tracking and Bluetooth notifications. Suunto places it under General settings or the Control panel, and says it activates automatically at 10% battery. That is distinct from choosing a battery mode for an exercise recording.
If notifications or daily tracking disappear when the battery gets low, inspect this setting before assuming the watch or phone connection is broken. Conversely, changing everyday Power saving is not a substitute for checking your exercise recording settings.

Try your intended settings before a long day
Use the proposed mode on a shorter familiar session first. Afterward, open the recording and check whether it contains the information you need: your route, timing and any relevant sensor data. The useful result is not simply that the battery lasted. It is that the saved activity still serves your purpose.
If you rely on heart rate to review workouts, a longer recording with that information missing may be the worse outcome. If you mainly want a record of a long outing, your priorities may be different.
Why the estimate can change
Suunto says charge duration depends on use and conditions, with low temperatures reducing it; rechargeable battery capacity also declines over time. That is why a personal trial is more informative than borrowing another owner's runtime.

Do you need a new watch?
Not until you have compared your present settings with the activity you want to record. If its usable modes cover your needs, keep it. If none preserve your required data for long enough, that gives you a concrete requirement for a replacement.
