Abstract

The invention relates to the technical field of intelligent terminals, and provides a mobile terminal. The mobile terminal comprises a charging interface, a charging switch, a power management chip, a first charging chip, a second charging chip, a first battery and a second battery, wherein the power management chip controls connection between a voltage inputting end and a voltage outputting end of the charging switch by using a control end of the charging switch so as to output voltage to the first charging chip and the second charging chip; and the first charging chip and the second charging chip simultaneously output voltage outputted by the charging switch to the first battery and / or the second battery so as to charge the first battery and / or the second battery. During quick charging of the mobile terminal, outputted large current is averagely distributed to the two charging chips and simultaneously charges the two batteries, the shortcoming that the temperature of the mobile terminal rises during quick charging of the mobile terminal is overcome, by the two batteries, the standby time of the mobile terminal is long, and the problem that the power of the mobile terminal is consumed quickly in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of intelligent terminals, in particular to a mobile terminal. Background technique [0002] As the entertainment and playability of smart terminals are getting higher and higher, the problem of high power consumption of mobile phones is becoming more and more serious. Therefore, the above problems are solved by fast charging, that is, high voltage or high current is usually used to realize the charging of smart terminals. Fast charging, whether it is a high-voltage method or a high-current method, in the process of fast charging, due to the limitation of the efficiency of the charging chip, the charging chip will generate a lot of heat. In addition, because there is only one battery in the mobile terminal, resulting in The mobile terminal consumes power quickly. To sum up, there are problems in the prior art that the temperature of the charging chip rises due to high current charging during fast char...
