Uninterruptedly powered handset and use method

Abstract

The invention discloses an uninterruptedly powered handset and a use method. The uninterruptedly powered handset comprises a main battery, an auxiliary battery and a power supply management and control module which is connected with two power supplies and controls the conducting state of the power supplies. The use method comprises the following steps: (1)connecting a main power supply, and disconnecting an auxiliary power supply; (2) supplying power to the handset by the main power supply; (3)checking whether the voltage of the main power supply is lower than working voltage or not; if so, executing step (4); if not, executing step (2); (4) displaying prompting information, disconnecting the main power supply, and connecting the auxiliary power supply; (5) supplying power to the handset by the auxiliary power supply; (6) checking whether the handset needs charging or not or the main battery needs changing; if so, executing step (2); if not executing step (7); (7) checking whether thevoltage of the auxiliary power supply is lower than latch voltage or not, if so, executing step (8), if not, executing step (6); (8) displaying prompting information; (9) checking whether the handsetneeds charging or the auxiliary battery needs changing; if so, executing step (6); if not, shutting down the handset.

Description

technical field [0001] The invention relates to an uninterrupted power supply system and a use method, in particular to a mobile phone with an uninterrupted power supply that automatically switches power sources and a use method. Background technique [0002] At present, mobile phones have more and more functions, such as: large-screen high-resolution display, photography with flash light, music or video playback, etc., resulting in a battery that usually does not last long. Generally, the video is played continuously, and the battery of an ordinary mobile phone can only be used for about 6 hours, and the battery has become very frequent. [0003] There is a common shortcoming in the mobile phone batteries generally used in the existing market: when the battery power is low, once there is a call incoming or outgoing, the mobile phone may automatically shut down during answering or talking. Even if it is found that the battery of the mobile phone is low in time, if it is cha...

Problems solved by technology

[0003] There is a common shortcoming in the mobile phone batteries commonly used in the existing market: when the battery power is low, once there is an incoming or outgoing call, the mobile phone may automatically shut down during the answering or talking.

[0005] 1. It takes a long time to turn on and off the machine, wasting time and energy

[0006] 2. Too many switches will have a great impact on the life of the mobile phone

[0007] 3. Sometimes the call must be terminated because of changing the battery, which is very inconvenient

[0008] 4. The mobile phone is shut down due to no electricity, so there is no buffer time

[0009] 5. Large radiation when switching on and off

The device does not have the function of automatically switching batteries, it must be switched manually, and there is a certain time delay when the sliding control switch 6 slides, which will cause the shutdown of the mobile phone and affect the ongoing work of the mobile phone
