One of the most common issues you might encounter is sudden and unexpected battery drain. This can happen for a lot of reasons, but the most common is that a process on the phone has run out of control and is causing problems. Usually, troubleshooting involves finding the specific process and stopping it.

You can do this by going into your phone settings and navigating to the battery section. The battery life stats for Samsung devices are under Device Care, while many other manufacturers keep it in the Settings menu under Battery. Once there, you should be able to see which apps have used the most battery under Battery Usage By App. The problematic process should be listed at the top.

From there, you have three options. You can reboot the phone and see if that resolves the issue. The second thing to try is going back into Settings, navigating to the Apps section, and force-stopping the app. Finally, you can uninstall and reinstall the app to see if that resolves the problem.

Occasionally, it might be a system process that causes the excessive battery drain. If that’s the case, you can still force close the process by going to the Apps section of Settings, tapping the three-dot menu button, and selecting Show System Apps. Find the problematic process and force close it. Other than that, your best option is to check the Play Store for app updates, the settings for a system update, or tap this link from your phone to see if Google Play Services needs an update.
