Don’t listen to the official, the reasons and solutions for the rapid battery drain of mobile phones are here

In winter, due to the low temperature, the activity of mobile phone lithium batteries decreases, and the batteries become less durable. In the past two years, Apple phones have been automatically shut down due to low temperatures, which has troubled many iPhone users.

However, with the development of technology, generally speaking, as long as it is not used in an extremely low temperature environment outdoors, there is no big problem. Many domestic Android phones are very strong in low temperature resistance and can be used normally even in minus dozens of degrees.

Low temperature is just a special external environmental factor. Many friends will find that the battery drains very quickly when using their mobile phones in daily life. Some even wake up in the morning to find that 20% of the battery is gone.

Why is this happening?

Recently, Qiao Zhongliang, deputy general manager of Xiaomi's Internet Department 1, posted in the Xiaomi community, saying that many "engine oil" users reported that the battery was consumed a bit too quickly, so he asked engineers to analyze everyone's feedback logs and summarized several reasons for the excessive power consumption.

The chart shows that the items that consume a relatively high proportion of power include not turning off the positioning service, applications consuming power too quickly (short videos, games, calls, etc.), the screen being set to always on, the screen being on at the highest brightness all the time, some applications starting automatically, and applications calling each other.

Qiao Zhongliang said that sometimes the positioning switch and Bluetooth switch are turned on by people actively, and the system cannot help people turn them off. Some applications start automatically because the applications guide people to turn them on, and people keep them on without paying attention, which leaves hidden dangers of power consumption.

But netizens are not buying it: If I can't open this and use that, am I buying a phone to keep it for later use?

Xiaomi's research may have its own particularities, so for ordinary mobile phone users, what is the reason why the phone's battery drains too quickly?

In fact, this is just like repairing a machine. You can find the problem by eliminating the problems step by step.

First, there is the battery factor.

First, check the degree of battery aging. Now many mobile phones can check the battery health. Once it is lower than 80%, you will obviously feel that the battery is not durable. At this time, you need to go to a regular channel to replace a new battery.

Second, check whether the charging head and charging cable match the phone. If the charging kit is not original or officially certified, it may cause a large amount of false power to be charged, that is, it is displayed as full, but the actual amount of power charged is not much. When using it, the power will "collapse".

Second, check the power consumption ranking of your phone.

Most mobile phones have power consumption ranking statistics in their settings.

You can see at a glance which hardware and software consumes the most power. Click on the most power-consuming application to see whether it is mainly consuming more power in the foreground (when in use) or in the background (when not in use).

Then, through startup management, you can selectively prohibit it from starting up or running in the background, which can greatly reduce its power consumption.

Third, usage habits.

Generally speaking, the rapid battery consumption of mobile phones is closely related to usage habits.

Simply put, the more apps and functions you open, the higher the settings, and the longer the screen is on, the more power it consumes.

After using an app, many people simply swipe up to suspend it, without completely shutting it down. Over time, there are more and more suspended apps, with dozens or even dozens of apps running at the same time in the background, which will definitely consume a lot of power. Therefore, you should develop the habit of cleaning up the background after using an app.

Some friends like to keep positioning, WiFi, Bluetooth and other functions turned on all the time, so they don’t have to turn them on specifically when they are needed, which is very convenient. Xiaoju recommends that you turn off these functions when not in use. Power consumption is one aspect, but more importantly, it can avoid unnecessary privacy leaks.

Nowadays, mobile phone screens are getting bigger and bigger, and high refresh rates have become popular. Many people pursue high refresh rates and high resolutions at the same time to bring a better visual experience, but at the same time, these usage habits will lead to higher power consumption. Here we recommend that you set the screen brightness to automatic adjustment; set the refresh rate to adaptive if it supports multiple levels, and only use high refresh when it is needed if it does not support it; select 2K resolution as needed; and turn off AOD off-screen display if you think it is not meaningful.

In addition, when watching videos or listening to music, you can use headphones, which will not disturb others and the sound quality will be better. If you use an external speaker, the power consumption will increase a lot. When taking pictures with your mobile phone, you can turn off the screen (some mobile phones will automatically turn off the screen), and then turn it on when taking pictures. The screen is always on when taking pictures, which consumes a lot of power.

Fourth, system optimization.

The degree of system optimization has a crucial impact on the power consumption of mobile phones. Many mobile phone brands will highlight their power-saving capabilities when promoting their own systems. In this regard, ordinary users can do little and can only adopt the methods we introduced above and wait for official system updates and optimizations.
