Problems solved by technology

When the battery is completely exhausted or overcharged, the battery itself is damaged, and the battery voltage cannot reach the saturation voltage, causing the battery to continue charging
Nowadays, smart phones consume fast power, basically charging once a day, so many users have the habit of charging their mobile phones before going to bed. The battery core short circuit, resulting in high temperature and high pressure and explosion

Abstract

The embodiment of the invention discloses a charging protection method and a terminal. The method comprises: if the terminal enters a charging state, judging whether the terminal meets a pre-set charging protection condition or not; if so, obtaining alarm clock time of the terminal and sleeping time of a user; calculating charging duration of a terminal battery according to the alarm clock time and the sleeping time; obtaining residual electricity of the terminal battery; and setting charging current of the terminal battery according to the residual electricity and the charging duration. By adopting the method provided by the invention, the terminal battery can be fully charged in the charging duration; and with regard to users who are used to charging while sleeping, a condition that the battery is in an overcharging state all the time after the battery is fully charged in a short time can be avoided, so that the service life of the battery is prolonged and the safety of the battery is improved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging protection method and a terminal. Background technique [0002] At present, in the charging process of mainstream mobile phones, two methods are generally used to control the charging situation. The first method is to use a charging IC chip to control the current. For example, a mobile phone will receive current quickly at the beginning of charging, then it will change to trickle charging, and finally when the battery reaches 100%, it will stop charging. The second is to use the charging IC to control the charging voltage during charging, and stop charging if the battery voltage reaches the set voltage. The above two methods are only suitable for ideal situations. When the battery is completely exhausted or overcharged, the battery itself is damaged, and the battery voltage cannot reach the saturation voltage, causing the battery to continue charging. Nowadays, ...
