Why does iphone5s consume so much power?

Location service is one of the reasons why mobile phones consume electricity. Find the "Settings" application on the home screen of the iPhone5s, click Open-find the "Privacy" column in the settings list, click Enter-in the privacy interface, click the "Location Service" option-and then click the "Close" button to close the location service. In the new iOS7 system, there is a new function that allows some applications to refresh in the background to get location information. Although the iPhone5s is equipped with M7 coprocessor, this function still consumes a certain amount of power. Or in the setting interface, find "location service is one of the reasons for the power consumption of mobile phones." Find the "Settings" application on the home screen of the iPhone5s, click Open-find the "Privacy" column in the settings list, click Enter-in the privacy interface, click the "Location Service" option-and then click the "Close" button to close the location service.

Mobile phone battery is an energy storage tool to provide power for mobile phones, which consists of three parts: battery core, protection circuit and shell. Generally, mobile phone batteries are lithium batteries and nickel-hydrogen batteries. MAh is the unit of battery capacity, and its Chinese name is MAh.

In the use of lithium batteries, it should be noted that after a period of time, the battery will enter a dormant state, when the capacity is lower than normal, and the use time will be shortened. However, the lithium battery is easy to activate, and it can be activated after 3-5 cycles of normal charge and discharge, and the normal capacity can be restored. Because of the characteristics of lithium battery itself, it has almost no memory effect. Therefore, the new lithium battery in the user's mobile phone does not need special methods and equipment in the activation process. Not only in theory, but also from my own practice, it is best to charge this "natural activation" way in a standard way from the beginning.

Memory effect is an effect that the contents of the battery crystallize because of the use of the battery. Generally, it only occurs in nickel-cadmium batteries, and there are fewer nickel-hydrogen batteries, but there is no such phenomenon in lithium batteries. The reason is that the repeated partial charging and discharging of the battery is incomplete. It will temporarily reduce the battery capacity, resulting in shorter talk time.
