Communication apparatus with charging reminder, and method

A communication apparatus (1), such as a mobile phone, a tablet computer or a laptop computer, provides charging reminders to the user of a connected peripheral device (14), such as a headset. The charging reminders are provided in dependence on an auxiliary status signal (AS) received from the peripheral device (14) and on detected charging events (ME), wherein a main charging event (ME) comprises a charging or replacement of a main battery (2) that energizes the communication apparatus (1). The auxiliary status signal (AS) indicates an auxiliary energy level (AL) of an auxiliary battery (15) of the peripheral device (14). The communication apparatus (1) detects low-battery conditions (LC), based on the indicated auxiliary energy level (AL), and provides notification signals (NS) for a user interface (11) to notify the user of the detected low-battery conditions (LC) in response to the detected main charging events (ME).The communication apparatus (1) acts to notify the user to conveniently charge or replace the auxiliary battery (15) of the peripheral device (14) together with the main battery (2) and thus prevent that the auxiliary battery (15) becomes discharged in the interval before a subsequent charging or replacement of a main battery (2). The communication apparatus (1) may aid its user in reducing the number of times a peripheral device (14) becomes inoperable due to a discharge of the battery (15).
