Battery Life and Care Tips

To get the most out of your tracker’s battery, it’s important to follow some simple care and usage tips.

Optimizing Daily Usage

Certain features, like GPS, heart rate monitoring, and always-on displays, can drain your battery quickly. To make your battery last longer:

• Adjust screen settings: Lower the brightness and reduce screen timeout duration.
• Manage notifications: Turn off app notifications that aren’t essential.
• Pause heart rate monitoring: Disable continuous tracking when you're at rest.
• Use power-saving modes: Activate these during sleep or when activity levels are low.

Temperature Considerations

Your tracker’s battery performs best when kept between 32°F and 104°F (0°C to 40°C). Avoid exposing it to direct sunlight or extreme temperatures, as these can cause permanent damage.

Smart Charging Practices

How you charge your device can directly impact its battery health. Here’s a quick guide:

Charging Practice	Impact on Battery Life	What to Do
Partial charges	Helps extend battery lifespan	Charge when the battery hits 20–30%.
Full discharges	Lowers battery capacity over time	Avoid letting the battery drain completely.
Continuous charging	Can overwork the battery	Unplug the device once it’s fully charged.

Maintenance Tips

Keep your device in top condition with these simple steps:

• Wipe charging contacts weekly with a dry cloth to prevent buildup.
• Install firmware updates as soon as they’re available.
• If storing the device for a while, keep it at around 50% charge in a cool, dry place.

Solar Charging Capabilities

Some trackers come with solar charging features, providing an extra boost to extend battery life when you’re outdoors.

Signs of Battery Issues

Be on the lookout for these warning signs:

• The battery drains much faster than usual.
• The device won’t charge fully or charges inconsistently.
• It frequently overheats during use or charging.

If these problems persist after trying software updates and resetting the device, it’s time to contact the manufacturer’s support team.
