When the main battery is low, you will see a low battery
icon (see “Status Icons” on page 44) in the navigation
bar and a callout that tells you to recharge the battery as
soon as possible. Your device uses both a detachable
main battery pack and an embedded backup battery
cell. When the main battery pack is removed or is
completely drained out, your device will shutdown. The
backup battery cell will then have 30 minutes to retain
data after which you risk losing all data on the internal
memory of your device.
