The battery life varies significantly depending on usage and radio conditions, but the following are general guidelines for how long the battery lasts on a single charge. If you receive a notification to "Please charge," we recommend charging as soon as possible.
In Battery Saver Mode (minimum interval of 3 minutes), the device is used for a total of 3 hours a day for round trips to and from school or cram school. It is not carried indoors, and not used on weekends. This estimation was calculated and tested based on the usage scenarios of elementary school students in a typical radio wave environment, and it refers to the period until the battery completely runs out, not just when the "low battery" notification appears.
Battery life can vary significantly depending on the radio wave environment and usage scenarios, so it is not guaranteed. Please consider it as a rough estimate.

If there are unread talks, the LED lamp will continue to blink. If left in this state for a long time, the battery may run out in 1 to 2 days.
If the lamp is blinking, please play the talks once.
If the device runs out of battery while in Sleep Mode, which does not detect movement, it may run out of battery without receiving the "Please charge" notification.
If the battery level of the device falls below 20% thresholds, you will receive a push notification on the app.
