Android operates as a universal platform, integrating numerous specialized processes that remain active in the background “just in case” users need them. This approach, while designed for versatility, can lead to significant drains on both your CPU and battery life—regardless of whether these functions are actively utilized.
Disabling Printer Service on Your Network
For many users, printing from an Android device is a seldom-used feature. However, by default, Android continuously scans for available printers on your local network, utilizing the mDNS protocol. This process involves actively polling your Wi-Fi network, checking for the presence of printers.
Although this scanning doesn’t require extensive resources, it maintains the Wi-Fi radio in high-power mode, consequently waking up the CPU. This results in unnecessary battery consumption even when printing isn’t a priority for you. To optimize performance, you can easily disable this feature by navigating to Settings → Connectivity → Printing and turning off all print services. Should you need to print, reactivating the service is a simple tap away.
Disabling Quick Share Device Polling
Quick Share facilitates effortless file sharing, yet it operates in the background to check for nearby devices even when not in use. Utilizing Bluetooth Low Energy (BLE), your device continually scans its surroundings and broadcasts its availability.
If Quick Share is not a frequent tool for you, consider disabling this background activity to conserve resources. Access the feature through Settings → Connectivity → Quick Share, and turn off Visible to nearby devices under Who can share with you.
By doing so, you’ll retain the ability to send files; however, you’d need to enable visibility for receiving files or employ a QR code for file reception.
Turning Off Usage & Diagnostics Tracking
Your device tracks application usage, battery metrics, and connection quality for both Google and your phone’s manufacturer. This data collection is intended to enhance the overall user experience, but it consumes valuable phone resources due to the constant logging and data transmission involved.
If you prefer not to contribute to this data pool, disabling the Usage & Diagnostics tracking is advisable. This setting varies by manufacturer but can usually be accessed by searching for “usage” in the Settings search bar. This will reveal both Google’s and your manufacturer’s tracking options, which you can disable with ease.
Disabling Background Wi-Fi and Bluetooth Scanning
One of the more debated settings in Android is the default scanning for Wi-Fi and Bluetooth devices, which continues even if those features are turned off. Google leverages this ongoing scan to create a mapping of device movements, improving location accuracy, especially indoors.
While it enhances functionality like the “Find My Device” feature, the battery consumption and privacy concerns are significant. If you do not find the benefits justify the resource drain, consider disabling this feature. Navigate to Settings → Location → Location services, and turn off both Wi-Fi scanning and Bluetooth scanning.
Turning Off Digital Wellbeing Tracking
The Digital Wellbeing feature is designed to help users understand their phone usage, promoting healthier interactions with technology by tracking unlocks, app usage, and notifications. However, this constant activity logging can be a substantial drain on battery life.
If you manage your screen time through alternative methods or are not concerned with these statistics, you may want to turn off Digital Wellbeing tracking. To do this, navigate to Settings → Digital Wellbeing & parental controls, tap the menu at the top-right, and select Manage your data. From there, toggle off Daily device usage to revoke usage access.
While these adjustments may not yield an immediate and dramatic improvement in your smartphone’s performance, they can enhance battery longevity and provide reassurance that your device isn’t expending energy on superfluous features.
