Problems solved by technology

However, in the case of low temperature, due to the abnormally large internal resistance of the battery, the voltage consumed by the internal resistance can reach 0.8V. The bottom is hidden, so the low temperature battery life is very short
This not only brings troubles to the normal use of mobile devices by users, but also causes users to fail to back up data in time, resulting in data loss

Abstract

Embodiments of the present invention provide a method and device for extending battery life, a storage medium, and a terminal device. In the present invention, at low temperature, by judging whether the change value of the battery core temperature and the difference are in a linear proportional relationship, if there is a proportional relationship, the shutdown voltage is adjusted to the first shutdown voltage, wherein the first shutdown voltage is less than 3.1 volts, Thereby improving battery life in low temperature environment.

Description

technical field [0001] The invention belongs to the field of terminal batteries, and in particular relates to a method and device for extending battery life, a storage medium, and a terminal device. Background technique [0002] With the development of mobile device technology, mobile devices have become objects that users carry with them. When the mobile device is in a relatively cold environment, the battery performance of the mobile device is greatly affected by the temperature. The internal resistance of the battery at low temperature increases by 10 times. 1500mΩ, the capacity is shortened to 1 / 2 of the normal temperature, for example: the nominal 3000mah, 4.4V battery, the capacity of -10 degrees is only about 1500mah At this time, even if the battery of the mobile device is fully charged, the mobile device may also lose power in a short time Automatic shut-down. In the current solution, the shutdown voltage at different temperatures is 3.1V. In this way, no matter w...
