Power Optimization and the Jolly Roger Phone Defender Android App

Some users will find that the Jolly Roger Phone Defender app will quit operating a short while after it has been started. For this app to properly function on some phones, power optimization needs to be shut off for the app. This ensures that the service remains active when the phone dozes. You don’t want to shut off power optimization for all apps on the phone, though, or you’ll find that your battery will drain quickly.

The instructions that follow work for Android 8.1 on some phones. Every phone manufacturer and service provider has the option to alter the look and feel of Android, so the actions to shut off power optimization will vary.

First, enter the settings menu on your phone, and look for Battery or Power. Touch this to continue.

When you are in this part of the menu system, touch the options/settings button on the upper right (the three dots shown here).

Choose Battery Optimization.

Once you are on the Battery optimization screen, use the menu at the top to select All apps. Some phones will have an option to show the optimized apps, which will also work.

Look for Jolly Roger. If it shows as “optimizing battery use,” you need to shut off optimization. Touch the app’s entry.


Tell it Don’t optimize, then touch DONE.
