The HC50 and HC55 allow you to swap out the main battery seamlessly while using all device functions, including the display, apps, and even voice and data activity.
When the main battery is removed, the display will dim slightly, and a timer will indicate that you have up to 60 seconds to complete the battery swap before the device shuts down. The HC50/HC55 supports a wide range of activity during a battery swap, but it is possible for unexpected events to cause a shutdown in some instances. The device may shutdown in less than 60 seconds when making calls in areas with very poor coverage, during an emergency call, or using the device's camera. To help prevent this, avoid starting new activities, such as launching apps or starting new calls during the battery swap.
If the backup battery is not sufficiently charged, a message indicates that the HC50 or HC55 is not yet ready for a battery swap. This message may display occasionally and will go away after a few minutes.
