AAA Carbon battery.Do mobile phones really need battery management apps?

　　Question: The mobile phone battery cannot last even one day. Can numerous battery apps really extend the battery life of the mobile phone?

　　Answer: Basically, all Battery Doctor and Butler applications use software to optimize and provide power-saving reminders for mobile phones, and are more about assisting. First of all, let’s start with the “three-stage charging function mainly promoted by battery management applications. The so-called “three-stage charging” includes fast charging, continuous supplementary charging and trickle charging; and battery management applications will not actually change the mobile phone. The charging mode of lithium battery is similar to a form of notification and time reminder.

　　Generally speaking, the current of a lithium battery will change significantly in two stages when charging. The current is larger at the beginning of charging, and then gradually decreases until it is fully charged. The so-called "trickle charging" refers to charging the phone for a while longer after charging. There are different opinions on whether it has actual effect. If you think it would be better to charge a little longer, you can calculate the time by yourself even without using the battery management app. , because the application cannot change the charging IC, it only serves as a theoretical reminder.

　　Secondly, battery management applications generally have a "deep charge and discharge reminder mode. It is recommended that you completely discharge and charge your phone once a month or so. This behavior actually has a certain meaning. For example, iPhone, Apple on its official website It is recommended that users perform a deep charge and discharge once a month to ensure the vitality of the lithium battery and extend its service life. Of course, the battery management application here is only a reminder.

　　As for the so-called "power saving mode", it is basically achieved by lowering the screen brightness and turning off the data network. Some Android applications also have the authority to reduce the processor frequency. Users can also adjust these operations in the settings. It is just a battery management application. More fool-proof. In addition, the battery application can also monitor the power consumption of hardware and software, and can determine whether the phone has installed malicious applications running in the background (mainly for Android). This function can also be found in the phone settings.
