How to save power on a mobile phone, send it to a mobile phone professional, and send it to developers.

Part of this is taken from the Internet. It is more of an experience on smartphones that have been used for so many years. I hope it will help you ~ If you have any ideas, you can help us to complete them together ~~ For most models, it should be a common power-saving method,Refined search
Please add Points for Attention !!

I. screen:

As a large power user, screen power consumption has always been a large part of daily use, so from this part of open-source throttling can effectively increase the battery unit time:

1.
Brightness adjustment

A large number of comparison tests show that the power consumption gap between the lowest brightness and the highest brightness can be about three times. Therefore, in daily use, reasonable screen brightness reduction can effectively reduce power consumption. Because the screen of Xiaomi mobile phone uses the semi-reverse half-transparent technology, it can effectively increase the visual effect under the strong light, when automatic brightness adjustment is used, the work of the light sensor also increases the power consumption. Therefore, it is recommended that TZ manually adjust the screen brightness to a suitable category.

2.
Automatically turn off the screen

When we do not operate the mobile phone for a long time, the screen will choose a delay Based on the preset in the user's settings to close the screen, in order to save power, many smartphone users may have a forced habit of lighting up the screen. Because the screen lock interface uses a large number of dynamic animations, its power consumption is slightly higher than when it enters the launcher, therefore, we recommend that you set the automatic screen off time to a smaller range based on your actual needs, which can reduce power consumption, increase usage time, and avoid exposing the target.

3.
Automatic Screen Rotation

As a universal function of today's smart machines, many people like to use this seemingly dazzling and practical function, but they are not aware of the operation of this function, it is not a simple implementation. It can be achieved only through the operation of the gravity sensor device, data collection, and overlay re-painting. Therefore, the function is enabled not only when the screen is in battle, for miui, our improvements on the home screen interface make launcher no longer need the rotation function (of course, text messages and other parts still have this requirement ), this function is only applicable to some third-party apps, such as games and map navigation. When working, these apps force change the display direction of the screen to adapt to their work. Therefore, if there are no other special interests in daily use, such as text message horizontal input, it is recommended that players disable this function.

4.
Switch screen Animation

Since the appearance of the "ns" screen animation similar to the TV shutdown, various screen animations have become a new way for talents to show their personality, but we don't want it! Why? Because we need to save power !!! This is like playing various graphics card killer games with PCs. You need high image quality, high details, and many animations. No problem! But what I pay is the increase in the power consumption of the video card and the increase in heat. Do I have to say more? Power-saving talents? Don't hesitate to turn it off!

5.
Dynamic Wallpaper

From the earliest neural grid to the various magical dynamic wallpapers that can now be played as a desktop game, it has increased the fun and personality of mobile phones, making it easier for many people, just like the above one, we want power saving! Do not affect machine performance! Therefore, do not use it.

6.
High-quality drawing/icon shadow

The above two settings are available for graphics icons in versions 2.3 and 4.0, which can improve the image details and visual experience. However, the implementation of this solution requires more GPU work, correspondingly, some power consumption will also be increased, resulting in the unit loss of power, so, for the sake of battery, turn off.

Ii. Wireless modules:

1.
WiFi settings

Nowadays, a large number of Wi-Fi hotspots have become the first choice for most users to access the Internet, there are two options in WiFi settings that need attention from power-saving talents:

(1)
Sleep Policy

After the Wi-Fi connection, you can set it to sleep with the screen off, not sleep during charging, and never sleep. When the WiFi sleep, the working rate can be reduced to of normal, therefore, we recommend that you set wifi to sleep when the screen is disabled if you have no special requirements, such as mobile phone downloads and chat tools, in this way, when a user uses a mobile phone, WiFi will be automatically connected, and the screen will be closed and disconnected, saving power.

(2)
Automatically search for WLAN

This function can scan nearby open network connections when WiFi is enabled, but for daily use, we will connect to a fixed hotspot for use, even if it is enabled next time, it will automatically connect, therefore, we recommend that you disable this function if you are not familiar with other scenarios, such as outdoors, so that you can take a break from wifi.

2.
GPS Positioning

When GPS is enabled, Android provides a mobile network-assisted positioning function. After GPS is enabled, it can communicate with the Carrier Base Station to perform secondary triangular positioning. In this way, the weather is not good, or assist when the satellite signal at the geographical location is weak. Therefore, disable this function to save power consumption if the preceding special conditions are not found.

3.
Network Type Selection

If you are a 3G user of China Unicom, you can select the preferred network type: 2G network, 3G only, and 3G, if you do not have many network applications or do not have any traffic plans, we recommend that you use a power-saving 2G network. If you are active in a city or region with a good network environment and have a lot of 3G resources, we recommend that you use the 3G only option to reduce switching between 2/3G networks. Of course, if you are in a tragic environment... If not, 3G is preferred.
---------------------------------------------------------------- I will cut it again --------------------------------------------------

3. Third-party applications

The previous sections are some suggestions for the system. The following sections are highly targeted content. I hope you can select a part suitable for your use habits:

1.
Various artifacts

A large number of users make friends and communicate with each other using software called artifacts. However, these artifacts have become a power-consuming user while helping you find the goddess, force-Refresh location information and other features make these software constantly eroded the battery, so we recommend that you ds, every time the use is complete, remember to go to process management to kill these things, or install some security software, disable the auto-start function after the instance is started.

2.
Navigation software

Thanks to the continuous improvement of GPS performance on mobile phones, many brothers will install professional navigation software on it, which is very convenient to find the path. But most people do not install the paid official version, so there may be some inexplicable problems, such as GPS still working after the shutdown and non-stop map server communication in the background. At this time, the power consumption will be greatly increased, therefore, we hope that when you use these solutions to crack the navigation, you will be able to kill them if they are disabled.

3.
Games

Similar to the navigation software, many games installed by gamers are now cracked versions, Chinese versions, simplified versions, and various versions. There are less or more active games mixed with various advertisements and backdoors, when you run these games when you start the data service, they will secretly consume your traffic in the background and eat away the power in the battery. In fact, the solution is very simple, as long as you are in the firewall, if you disable the Internet permissions of these apps, you can enjoy it without any worries.

Recently, I have read an article from Xiaomi, sharing the power consumption with you has become the bottleneck of smartphone development. As an app developer, we also need to consider the power consumption of programs, otherwise, your app will be discarded one day due to excessive power consumption.
