When a user activates the battery case, it can transfer stored power to the Galaxy S3. This process ensures that the phone’s battery is recharged while still in use.
Scenario examples that illustrate the importance of the rechargeable feature include a user traveling during a long commute or attending events where charging facilities are scarce. In these cases, having a power case ensures that the smartphone remains operational to serve the user’s needs without interruption.
