Have you ever gone to bed with your Android battery fully charged, but when you wake up in the morning your phone is completely drained? If the answer is yes, you may be affected by the Wakelock app installed on your smartphone. Of course, this could also be due to poor battery health. However, system locked situations, caused by misbehaving apps that use up the phone’s resources and drain the battery, can occur even on healthy devices.

To better understand this, we will take a look at what wakelocks are when it comes to Android and how we can detect and fix the problem for better battery life.
What are wakelocks?
When you press the power button on your phone to lock the screen, you assume the phone will go to sleep. But that’s not always the case. There are apps that run in the background, using the device’s resources and restricting the phone from going into deep sleep. As a result, the phone’s processor is constantly working, draining the battery even when you’re not using it. Most of these wake-up errors are caused by apps that want to sync data in the background or use location services.
Therefore, the apps that keep your CPU running even when the phone is in sleep mode are called Wakelock apps. However, these apps are not entirely to blame. These wake-up keys are necessary if you want to see your email inbox updated in the morning. The app uses permissions to sync data with the server, which sometimes lasts only a few minutes.
The problem started when some apps used this permission for about an hour and kept your phone CPU running all the time. Take Google Play Services as an example. If you have your location turned on, this service will keep your phone’s CPU running most of the night and drastically reduce battery life.
So now that we know what wakelocks are, let’s see how we can detect the apps that are causing it.
Note: Since we will need elevated permissions to access this data, root access is required. Without root privileges on your device, I’m afraid there’s not much you can do about the Wakelock issue. However, rooting a device is easy these days, so don’t forget to bookmark this page and come back to it once you’ve figured out how to root your Android (and root it, too).
Detect app causing wakelocks
Detecting wake lock is pretty easy when you have a rooted phone. Fully charge your battery to 100% and install an app called Wakelock Detector on your device. Once done with that, reboot your phone once and launch the app. Wakelock Detector will require root access and run in the background to collect data.
Come back to the app in a few hours and you’ll be able to see the total time your apps have kept the CPU running in the background. You can also check how many times the app triggers Wakelock.
Problem solving
So now that we know the apps that are causing these wake up errors, one of the easiest options is to uninstall the app and find a better alternative on the Play Store. However, there are system apps like Google Play Services that you cannot uninstall. These apps are required for the phone to work.
To test such apps, you can install an Xposed module called Amplify. Amplify is basically a battery saver app for Android, but unlike others, it has a module to restrict wake requests from different apps installed on the system. your. select Rear lock options from the right-hand navigation bar. Select the permission you want to restrict and specify a favorable time period. The app also provides a recommended setting for troubleshooting.
Conclusion
That’s pretty much everything about Wakelocks on Android and how to fix the battery problems they can cause. Those experiencing high battery drain due to Google Location Services running in the background must try it out.
