APP culminating in the power consumption of the mobile phone

"multi-tasking" is a smart phone label, those apps that are always running in the background can be on call, let you drive. However, some of the APPs may also consume extra power due to frequent wake-up of the CPU in the lock screen state. So, how can we get rid of the power culprits and do targeted bans or optimizations? Wakelock is a disaster. "Wakelock" is the power management mechanism of the Android system. Many third-party apps will be given the right to call Wakelock after installation. Even in the lock screen standby state, these apps can still be dormant ( Deep Sleep state, frequently wake up the CPU for data exchange or information push. If you have a large number of such apps installed on your phone, it’s blameless without any electricity. Tips Many Android phones will automatically down-clock after the lock screen, and Wakelock will prevent the system from going to sleep after being called by APP. Even if the CPU is always running at 400MHz, it will consume extra power. WakelockDetecor to help Wakelock Detecor is a system detection tool, after installing and running on the phone, click the icon in the upper right corner to switch between the screen wake-up, CPU wake-up and wake-up trigger, click the CPU wake-up device List all the apps that sneaked over the CPU from the back of the last charge and how long they have been awakened; click on the wake-up trigger to see how many times each app has triggered Wakelock (Figure 1). I don’t know, I’m scared. After I used the phone for about 1 day, I have never started a lot of apps, but it has been triggered for hundreds of times (Figure 2), and some apps have been waking up the CPU for more than 10 minutes (Figure 3). ). Be aware that these are the culprit in the inadvertent loss of battery power. Let the blacklist APP hibernate to grasp which APP is the power culprits, we can then use another software & ldquo; APP hibernate masters rdquo; let these unreliable APP hibernate. After running the software to add the app to the hibernation list, all the services of these apps will not be started (Figure 4), and naturally the Wakelock will not be able to wake up the CPU. Tips For the use of APP hibernation masters, please refer to this article in the 03 issue of "Let APP hibernate experience Android non-general smooth feeling". In addition, software such as Weibo WeChat QQ needs to be treated differently, and if they are hibernated, they cannot accept push messages. This article comes from [System Home] www.xp85.com
