Fixing LineageOS Keeps Waking: A Comprehensive Guide

One of the most annoying problems is LineageOS keeps waking, especially for people with their screens constantly waking and thereby potentially wasting more battery life. Be it when your screen wakes up every 5 seconds, or simply goes wild showing no proper activity, it would hamper user experience in various ways. Therefore, this article will guide you step by step through diagnosing and fixing the issue of LineageOS keeps waking to allow for the normal smooth running of your device.

Understanding the Reasons for LineageOS Keeps Waking

The LineageOS keeps waking problem is normally brought about by a variety of reasons, including:

1. Poorly Configured Notifications: Some applications may be unnecessarily causing wake events.
2. Background Processes: Some rogue applications running in the background may be the cause of frequent screen wake-ups.
3. System Wakelocks: Kernel-level wakelocks may cause periodic screen activations.
4. Hardware Triggers: Faulty power buttons, proximity sensors, or fingerprint scanners may accidentally wake up the device.
5. Custom ROM Tweaks: Improper configuration in custom kernels or Magisk modules can be a reason for the inconsistent wake pattern.

Step 1: Check App Notification Settings

Different applications with too aggressive notification settings may be the reason for LineageOS keeps waking. The following will be used to address this:

1. Check Notification Access:
   • In Settings, tap Apps & notifications then Special app access > Notification access.

• Find apps with notification permissions and turn off all unnecessary access.

2. Reduce High-Priority Notifications: Open Settings > Apps & notifications > See all apps. For each app, go to App info > Notifications and turn off all high-priority settings.

3. Disable Edge Lighting: If your device supports edge lighting for notifications, disable it in Settings > Display > Edge Lighting.

Step 2: Identify Background Processes Using Wakelocks

Wakelocks are often the culprits behind the LineageOS keeps waking issue. Use the following tools to identify problematic apps:

1. Install Wakelock Detector:
   • Download and install Wakelock Detector from a trusted source.
   • Grant necessary permissions using ADB or root access:

     adb shell pm grant com.uzumapps.wakelockdetector android.permission.BATTERY_STATS
     

wakelock statistics. Here are some simple, yet important tips:

2. Analyze Battery Usage • Launch Settings > Battery > Battery Usage. • Take a note of applications consuming more power relative to others and restrict background usage.
3. Make use of BetterBatteryStats • Download the BetterBatteryStats app in order to obtain enhanced information regarding kernel wakelocks, partial wakelocks, and alarms. • Set up the application for kernel wakelocks, partial wakelocks, and alarm tracking.

Step 3: Disabling Problem Services on LineageOS Some problem services on LineageOS that will wake up apparently for no good reason: easy enough to be turned off. First of all:

1. Disable Ambient Display Go into Settings > Display > Ambient Display and deactivate it.

2. Deactivate Double Tap to Wake: Now go into the Settings > Gestures > Double Tap to Wake to deactivate this.

3. Altering Doze Settings:

• Head to Settings > Battery > Adaptive Battery and enable it.
  • Use ADB commands to tweak Doze parameters:

adb shell dumpsys deviceidle

adb shell settings put global low_power 1

Step 4: Troubleshoot Hardware Triggers

Hardware parts, like power buttons and sensors, may wake up your device by mistake. Troubleshooting steps:

1. Power Button Test: The power button is either sticky or too sensitive. Use a third-party application like Button Mapper to remap or disable the power button.

2. Calibrate Proximity Sensors: Download and install any sensor calibration application from the Play Store.

• On-screen instructions to recalibrate your proximity sensor.

3. Sensitivity of Fingerprint Scanner:
   • Go to Settings > Security > Fingerprint and disable screen wake for fingerprint detection.

Step 5: Kernel and Magisk Modules Optimization

Custom kernels and Magisk modules are also among the most common causes of wake-up issues. Here’s how to optimize them:

1. Reconfigure Custom Kernels:

• Use applications such as Franco Kernel Manager or EX Kernel Manager to edit wake settings.
  • Disable CPU governors or scheduler tweaks that are not necessary.

2. Audit Magisk Modules:

   • Open Magisk Manager and look at installed modules.
   • Remove or disable any module related to wakes, like Ambient Wake Gestures or Quick Wake.

3. Reset Kernel Defaults:

• Flash your kernel’s default configuration file or re-flash the kernel zip through recovery mode.

Step 6: Advanced Tools for Persistent Problems

For more persistent cases of LineageOS keeps waking, advanced tools may be necessary:

1. ADB Commands to Disable Wake Events:
   • Use ADB to block specific wake events:

adb shell settings put global wake_gesture_enabled 0

adb shell settings put secure doze_enabled 1

2. Install Greenify or Naptime: Download Greenify to hibernate apps that cause frequent wake-ups. Use Naptime to improve Doze settings and cut down on unneeded wake events.
3. Flash a Stock ROM:

• Flashes stock ROM to reset all settings and gets rid of wake-ups in case none of the above steps work.

Step 7: Verify Fix and Monitor It

Finally, after these steps have been executed, confirmation that this problem has been solved should be made in the following way:

1. Reboot Device: Do this just in case, to apply changes.
2. Examine Waketimes:
   • Use Wakelock Detector or BetterBatteryStats to make sure no more abusive wakelocks set.

• Check Settings > Battery for any major improvements in standby time.

3. Test Notifications and Gestures:
   • Verify that the important notifications and gestures work as expected without causing unnecessary wake-ups.
