Abstract

The invention provides a handheld mobile terminal and a power supply thereof; the power supply device comprises at least two batteries, a detection module, a judgment module and a switching module; wherein, one battery is a current power supply battery and the other battery is a non-current power supply battery; the detection module is used for detecting the power supply voltage of the current power supply battery, and transmitting the detection result to the judgment module; the judgment module is used for judging if a switching signal is sent to the switching module according to the detection result; and the switching module is used for switching the non-current power supply battery to supply power for the handheld mobile terminal according to the switching signal. The invention improves the electrified use time of the handheld mobile terminal and prevents the unnecessary trouble due to sudden power supply cutoff of the handheld mobile terminal in use.

Description

technical field [0001] The present invention relates to the application field of hand-held mobile terminals, in particular to a hand-held mobile terminal and a power supply device thereof. Background technique [0002] In recent years, with the development of wireless communication technology, mobile phones have become an indispensable communication tool in people's lives. With the development of modern information business, users have higher and higher requirements for mobile phone standby time and talk time. The standby time and talk time of mobile phones have become one of the important criteria for users to choose mobile phones. The longer the standby time and talk time, the more favored they are by users. Usually, the length of the standby time and the talk time all depend on the capacity of the battery, and the battery capacity has a certain relationship with the battery volume. However, with the trend of miniaturization of modern technology mobile phones, the volume...
