Have you ever faced a situation, where you sleep off with your Android phone having ample battery, but wake up to a completely drained phone in the morning even if you haven’t used it? If the answer is yes, and if it happens frequently then there are generally two major reasons behind it. One is due to the poor battery health, which occurs in older phones, and the second and the most common reason is the battery drain by the wakelock apps. Battery drain due to the misbehaving wakelock Android apps can even happen in new and healthy phones, so if your phone’s battery is dying earlier than normal it should be, then this could be the reason.
To have a better understanding of the issue, let’s look at what wakelocks are and how to fix them for better battery life.
What is a wakelock?
Generally, when you press the power button on your phone to lock it, you assume that the phone goes to the sleep mode. However, that not the case always. Sometimes, there are apps that run in the background and use the data and battery sevices of the phone even when it’s locked. These apps make sure that the phone’s processor keeps on running even after the device is locked, which results in battery drain. Mostly, wakelocks are caused because the apps sync data in the background and use the location services even when the phone is locked.
These apps keep the processor and the CPU running even after your phone is in the sleep mode, which is why they are called as wakelock apps. Wakelocks are neccesary in some cases, like getting your emails and notifications while the phone is in sleep mode, and in some, they are just there to drain your phone’s battery out. As long as the apps installed in your phone use their background access permission limited you wouldn’t find any problem, but once they run for long hours and they start using your phone’s CPU, you’ll start experiencing problems.
How to identify apps causing wakelocks?
You can easily detect the wakelocks in your phone, all you need to do is just follow the steps given below.
- Go to the settings in your Android smartphone.
- Select battery.
- Once you do it, you’ll be able to see the total battery left and even the apps that use the highest battery.
- Click on the apps to check for wakelocks.
- If you see any process that reads “keep awake” or “stay awake” in the app, it means that the app is using wakelock to keep your phone awake even when it’s locked.
These steps only let you know if your device is affected by the wakelocks or not, but it doesn’t help you identify the apps causing it.
How to fix the wakelock issue on your Android phone?
This is a tricky thing to stop the apps from causing wakelocks but thankfully there’s an app in the Google Play Store that could detect the wakelocks easily and help us know the apps causing the highest wakelocks. However, the app requires you to root your Android phone to get the information about the apps causing wakelocks. Rooting is not a general thing and for a regular user, rooting might seem like a huge task, which is why here are some steps that could help you detect the wakelock causing apps without rooting your device.
- The first step is to enable the Developer Options on your phone. You can do it by going to Settings -> System -> About Device -> Build Number. Once you see the Build Number click on it for 7 to 8 times, which will enable the Developer Options in your settings menu.
- Once you enable the Developer Options, open it and enable the USB Debugging options.
- Now download the Wakelock Detector Lite app from the Google Play Store or just Click Here. Install the app on your device. Remember, you need to download the Lite version of the app as it works on the unrooted devices. The app is available for free but you might need to purchase the premium version to unlock all its features.
- Don’t open the app directly. Find a PC and install Chrome, and the Chrome extension named as Wakelock Unlocker. Click on the link here to find the extension and install it.
- If you’re using a pc running on Windows then you’ll have to install Universal ADB Driver to make sure the Chrome extension works.
- After the aforementioned steps, connect your phone using a USB.
- You’ll now see the Chrome Wakelock Unlocker detecting your phone and if not you can do it from the ADB server manually.
- Once you see your phone in the extension, select the Grant Battery Stats to enable the app installed on your Android phone.
When you complete all the aforementioned steps, you’ll have the app configured and ready to use in your device. Open the app and wait for a few seconds, you’ll be then provided with the information about apps that use the wakelock feature the most.
Once you find out the apps draining most of your phone’s battery life due to wakelock, there’s nothing much you can do. However, if you want to reduce the wakelocks, you can uninstall the apps that use most of your battery or else you can even write to the app developers asking to update it.
