Many Android users and developers face situations where a device needs to be restarted repeatedly for testing, debugging, or recovery purposes. Manually pressing the power button can be a drain on productivity. Fortunately, the Android Debug Bridge offers a straightforward yet robust way to automate device reboots using batch files. With just a minimal script, you can schedule restarts, launch reboots in response to logs or errors, or even integrate reboots into larger automation workflows.

To get started, you must turn on ADB access on your Android device. This setting is located under Developer Options in the System Preferences. If you are missing Developer Options, you can reveal it by tapping the Build Number seven times in the About Device section. Once USB debugging is activated, connect your device to your computer via USB and launch Command Prompt. Run the command adb shell devices to check this out if detected. If your device shows up with a device ID, you’re ready to proceed.

The standard command to reboot a device is adb reboot-system. Typing this into your terminal will trigger a full reboot of your connected device. To reduce manual input, you can build a reusable script. On Windows, create a batch file named adb-reboot.bat with the content adb shell reboot. On macOS or Linux, create a .sh file named reboot-device.sh with the same line and grant execution permissions with sudo chmod +x.. Now you can initiate a reboot via GUI instead of re-entering the command manually.

For complex workflows, you can strategically sequence operations. For example, you might want to delete a package, cycle power, and restore. A script could look like this: app.apk. The delay function gives the device time to fully restart before attempting to deploy the package again. You can tweak the delay based on your device’s startup speed.

You can even schedule automatic reboots using your system’s task scheduler. On Windows, use Scheduled Tasks to trigger the.bat every day at 3 AM. On macOS or Linux, use cron to set up a recurring reboot. For example, adding reboot-device.sh to your cron configuration will force a daily cycle at 03:00. This is especially useful devices left running for long periods like public terminals.

When working with several connected Android units, you can select an individual phone by using its device ID. First, list all connected devices with adb shell devices. Then use adb -s reboot to isolate control. This is critical in testing environments where several devices are connected.

Keep in mind that certain models may require a vendor-specific ADB driver or may lose connection post-restart if USB debugging is reset on power cycle. Most modern Android versions handle this reliably, but validating your configuration is highly suggested. Also, limit the number of restarts as it may reduce the lifespan of the device's storage.

Automating reboots with ADB dramatically cuts manual labor but also increases consistency in development workflows. Whether you are a developer testing app behavior after a restart or an system operator overseeing multiple units, these scripts transform a tedious task into a automated component. With zero extra software and a single script, you can achieve precise oversight of your Android devices from your computer.
