Optimized battery life for Android devices)

"Whenever we talk about the bottleneck of mobile smart devices, we always think of battery endurance. The battery life is not only related to the hardware of the device, but also to applications running on the device.ProgramClosely related.

When the battery capacity cannot be greatly increased in a short period of time, the battery life can be prolonged by optimizing applications to save power. At the same time, it also gives mobile app developers a new understanding of the power consumption of applications, and perhaps power saving can also become a kind of competitiveness of applications ."

To make your applications better available on your devices, it is necessary to restrict the impact of programs on the battery. After learning this article, you can create a program to change the function or behavior based on the battery status of your device.

To reduce the impact of your program on battery endurance and user experience, you can use the following methods, for example, when a device loses connection to the Internet, you should not automatically update the services running in the background, or reduce the update frequency when the battery power of your device is low.

Based on the official tutorial, this article will introduce how to make your program have less impact on the battery, so as to optimize the battery life. The tutorial mainly includes four aspects:

Monitor battery power and battery charging status (monitoring the battery level and charging state );

Determine and listen to dockingStatus and type(Determining and monitoring the docking state and type );

Determining and monitoring the connectivity status)

Manage broadcast receivers ( manipulating broadcast receivers on demand )
