Battery Dead Timer / User interface design

Battery Dead Timer

The product tells the amount of the battery by time and informs users of the turn-off time.

Users can use the smartphone in their hour of need by watching the time if the phone tells the remaining amount of the battery by time instead of the percentage. They will also try not to use the phone if the turn-off time comes near. Then, users will use the phone only when they really need it and the social problem of the lack of communication between people caused by the use of the mobile phone will be reduced.
