This software can extend the battery life of Android phones by 16%

iOS 9 has been released, and one of the highlights is the upgrade in battery life. In daily use, the battery life is extended by one hour. In addition, an ultra-low power mode has been added to the iOS version, which can increase the battery life by three hours.

It has to be said that just like Wi-Fi is our life (black again), battery is the life of smartphones. Nowadays, smartphones are charged once a day. Although new batteries emerge in an endless stream, it is still a bit difficult to fundamentally change the current lithium battery market.

Isn’t there a simpler way to change the current battery life? The answer is yes! And it can be done with code.

Researchers from Purdue University, Intel Corporation and Mobile Enerlytics conducted a smartphone battery life study on 2,000 Samsung Galaxy S3 and S4 units in 61 countries, covering 191 mobile operators.

The study found that 45.9% of battery power is consumed when the screen is locked, and more than half of that is due to the running of background programs (28.9%).

"When the screen is locked, the mobile phone application should enter the dormant state, so that the battery consumption is close to zero. However, due to the incorrect use of Wakelocks, the application still runs in the lock screen state."

Wakelock is the power management mechanism of the Android system. Many third-party apps will be given the permission to call Wakelock after installation. Even in the lock screen standby state, these apps can still be in the never-sleep (Deep Sleep) state, frequently waking up the CPU for data exchange or information push.

The researchers also provided a solution called HUSH, which can determine the importance of applications based on their usage and limit the operation of unimportant applications. According to sciencealert, this solution can reduce battery consumption by 15.7%.

The researchers have provided the details of HUSH on GitHub. However, it does not exist in the form of a plug-in, but requires users to improve the code themselves. However, the researchers said that they plan to improve this solution in the near future, so Android newbies should be patient, and soon your battery life will be longer.
