cardoO Watch Battery Draining Fast

Battery life depends on device age and usage. Follow these steps if your watch seems to drain faster than expected.

Make it last longer

Keep your phone nearby: Bluetooth is more efficient than standalone use.
Prefer Wi-Fi when away from the phone instead of cellular (if supported).
Strong signal or Airplane Mode: in poor-coverage areas, turn Airplane Mode on to save power.
Enable Low Power Mode: Control Center › Battery percent › Low Power Mode. It turns off automatically above 80% charge.
Turn off Always-On Display (if supported): Settings › Display & Brightness › Always On → off.
Temporarily disable battery optimizations: Settings › Battery › Battery Health, turn off Optimized Charging / Charge Limit (Off until tomorrow).
Long workouts: to save power on outdoor walk/run/hike, enable Reduce GPS & HR sampling: Settings › Workout.
Audio: use Bluetooth earbuds instead of the built-in speaker.

Some post-update tasks run in the background. If battery life drops after a software update, give it 2–3 days and check again.

On the watch: Settings › Battery › Battery Health.
Review Maximum Capacity.
If you see Battery needs service or capacity is notably low, consider service.

If the issue persists:

Book an appointment at a cardoO Service Center to test or replace the battery with a genuine part.
