Battery Guru: Advanced Power Management & Wakelock Detector

Battery Guru bridges the gap between passive monitoring and active system optimization. While many apps simply watch your battery drain, Battery Guru provides the tools to stop it. It is designed for power users who want to modify how the Android system handles background processes, offering granular control over Doze modes and deep sleep states that are usually hidden from the average user.

How to Get Started with Battery Guru

To unlock Battery Guru’s full potential without rooting, you will need to grant special permissions via ADB (Android Debug Bridge).

1. Initial Calibration – Unlike others, Battery Guru requires a specific 15% to 100% charge to verify health.
2. Grant Write Secure Settings – Use a PC to run the ADB command provided in the setup guide.
3. Enable Doze Features – Once permissions are granted, activate “Aggressive Doze” to silence background apps.
4. Configure Wakelock Detector – Allow the app to identify which specific services are preventing sleep.

Who Should Use Battery Guru

This app is tailored for users comfortable with technical tinkering to squeeze every milliamp out of their device.

• Power Users – Users willing to use ADB or Root to unlock system-level modifiers.
• Old Device Owners – People with aging batteries who need aggressive software optimization to last the day.
• Privacy Advocates – Users who appreciate the clear distinction between ad-supported and paid privacy.
• NOT ideal for – Casual users who want a “set it and forget it” experience without configuration.

Battery Guru Platform Compatibility

Battery Guru is deeply integrated with the Android operating system’s power management APIs, making it exclusive to that platform.
