Fully charge the device and record its continuous operating time. If it is significantly less than 2 hours, confirm that the battery life has degraded.
② Usage Habits:
If frequently let the device shut down automatically before charging. Long-term over-discharging can damage battery capacity.
③ Temperature Observation:
Avoid using the device in excessively cold or hot environments and check if battery performance returns to normal.
