Garmin Enduro Solar & Battery Modes Setup

Setting up solar charging and battery modes on your Garmin Enduro helps you extend battery life significantly, especially during long outdoor activities. This guide explains how to configure power modes, enable solar charging effectively, and manage battery settings to get the most out of your watch. You’ll learn the exact steps to adjust settings on the watch itself and via the Garmin Connect app.

What You’ll Need

Garmin Enduro (original or Enduro 2) watch
Garmin Connect app installed on your smartphone (optional but recommended)
Access to the watch’s settings menu (usually via the MENU button)

Step-by-Step

Access Power Modes: Press the MENU button (top left) on your watch. Scroll down to Power Modes and select it. This opens the list of pre-configured modes like GPS, UltraTrac, and Expedition.
Create a Custom Power Mode (Optional): If you want a mode tailored to your needs, select Add New or the plus icon. Name it (e.g., “Hike Solar”). You can base it on an existing mode to start.
Customize Settings: In the power mode editor, you’ll see options like GPS, Satellite, Wrist Heart Rate, Backlight, Timeout, and Music. Adjust each to balance accuracy and battery drain. For maximum battery, set GPS to UltraTrac, disable wrist HR, and set backlight to Low or Off.
Enable Solar Charging: Solar charging is automatic on the Enduro – the Power Glass lens charges whenever exposed to sunlight. However, you can maximize it by ensuring the watch is not covered by a sleeve. In the power mode settings, there is no direct toggle for solar; it’s always active. But you can check the solar intensity in the Battery Manager widget.
Set Battery Saver: Go to Settings > Battery > Battery Saver. Toggle it on to automatically reduce features when battery is low. You can set a threshold (e.g., 20%) and choose which features to disable (e.g., Bluetooth, notifications).
Use Battery Manager: From the watch face, press UP or DOWN to scroll to the Battery Manager widget. It shows current battery percentage, estimated remaining time, and solar intensity (in lux). Use this to monitor how much solar charge you’re getting.
Configure Activity Profiles: For each activity (e.g., Run, Hike), you can assign a power mode. While in the activity settings, go to Power Mode and select the mode you created. This ensures the watch uses your optimized settings during that activity.
Adjust Display Timeout: In Settings > Display > Timeout, set it to a short duration (e.g., 15 seconds). This reduces battery drain from the screen staying on.
Disable Unused Features: Turn off features you don’t need, such as Pulse Ox (Settings > Wrist Heart Rate > Pulse Ox), Activity Tracking, or Smart Notifications. Each of these consumes battery.
Update Software: Ensure your watch firmware is up to date. Garmin often releases updates that improve battery efficiency. Check via Garmin Connect app or the watch’s Settings > About.

Common Mistakes

Covering the watch face: Wearing the watch under a sleeve or in a pocket prevents solar charging. Keep the face exposed to direct light.
Using high-accuracy GPS unnecessarily: GPS mode with all satellite systems drains battery faster. Use UltraTrac for long activities where precise tracking isn’t critical.
Leaving backlight on high: A bright backlight with a long timeout can consume a lot of power. Set it to low and short timeout.
Forgetting to assign power modes: Creating a custom power mode doesn’t automatically apply it. You must assign it to each activity profile.
Expecting solar to charge while indoors: Solar charging requires direct sunlight. Indoor lighting provides negligible power.

Tips

Use Expedition mode for multi-day trips: This mode disables GPS logging to a minimum and uses solar to potentially extend battery life for weeks.
Charge before long activities: Even with solar, starting with a full battery is best. Solar can only extend, not rapidly recharge.
Monitor solar intensity: In the Battery Manager widget, a solar intensity reading above 1000 lux means good charging conditions. Aim to keep the watch face angled toward the sun.
Create a “Battery Saver” power mode: Duplicate the default Battery Saver mode and adjust it to your liking. This gives you quick access to a low-power mode.
Use the Garmin Connect app: You can edit power modes and battery settings from the app, which is easier for detailed changes. Sync after editing.

Troubleshooting

Solar charging not working: Ensure the lens is clean and not scratched. If the watch is in battery saver mode, solar still works, but check the Battery Manager widget to see if it’s showing ‘Solar’ and a lux value. If not, try restarting the watch.
Battery drains faster than expected: Check if any activity is running in the background. Also, verify that the backlight isn’t set to ‘On’ always. Reset to default power modes if needed.
Power mode not appearing in activity: Go to the activity’s settings, select Power Mode, and ensure you’ve chosen the correct mode. Sometimes you need to scroll to find it.
Watch not syncing settings from app: Make sure Bluetooth is on and the Garmin Connect app is up to date. Try turning the watch off and on again.
Battery percentage drops suddenly: This can happen after a software update. Give it a day to recalibrate. If it persists, contact Garmin support.

Frequently Asked Questions

Q: Does solar charging work in all weather?
A: Solar charging requires direct sunlight. Overcast days or indoor lighting provide very little charge, so rely on battery for those conditions.

Q: Can I use solar charging while wearing the watch?
A: Yes, as long as the watch face is exposed to sunlight. It charges continuously during the day.

Q: What is the difference between Battery Saver and a custom power mode?
A: Battery Saver is a preset that automatically activates at a set battery level. A custom power mode is a manual setting you can assign to activities.

Q: How long does the battery last with solar charging?
A: In smartwatch mode, Garmin claims up to 50 days with solar (assuming 3 hours of direct sunlight per day). In GPS mode, it’s up to 100 hours with solar. Actual results vary.

Q: Can I turn off solar charging?
A: No, solar charging is always active. You can’t disable it, but you can cover the lens if you prefer not to charge.

Q: Does using a watch face with a lot of widgets affect battery?
A: Yes, some watch faces with animations or frequent updates use more battery. Choose a simple face for better battery life.
