While the Pixel 9a already offers impressive battery life with over 30 hours of normal use and up to 100 hours with Extreme Battery Saver, there are ways to further extend its battery life using third-party apps and accessories.
Third-Party Apps
1. Brevent: This app allows you to control background applications, syncing, and running processes. It requires Termux and Shizuku to function fully, which can be set up to manage other apps effectively. Brevent needs an adb command to be run every time the phone is rebooted, making it a bit more complex to use but highly effective in managing battery-draining apps[5].
2. Naptime: This app forces the Android built-in doze mode to work more aggressively once the screen is turned off. It can significantly reduce battery drain during periods of inactivity, such as when you're asleep[5].
3. QBoost: Although primarily designed for Snapdragon versions of other phones, if compatible, QBoost can create processes to optimize performance or save battery. However, its compatibility with the Pixel 9a is uncertain without further testing[5].
Accessories
1. MagSafe Cases: While traditionally associated with iPhones, using a MagSafe-compatible case with a Pixel device that supports Qi wireless charging can improve charging efficiency. This is because MagSafe cases help align the phone better with wireless chargers, reducing energy waste during charging sessions[4].
2. Efficient Wireless Chargers: Using Qi-certified EPP chargers can ensure optimal wireless charging speeds. For the Pixel 9a, wireless charging is supported up to 7.5W with compatible chargers[6].
Additional Tips
- Adjust Display Settings: Lowering the screen brightness and reducing the refresh rate from 120Hz to 60Hz can significantly conserve battery life[4].
- Limit Connectivity Features: Turning off features like 5G, Bluetooth, and GPS when not in use can save power[4].
- Dark Mode: Enabling dark mode can reduce battery consumption, especially on OLED displays like the Pixel 9a's[4].
- Background App Management: Regularly check and manage background apps to prevent unnecessary battery drain[4].
By combining these strategies, you can further optimize the Pixel 9a's battery life beyond its built-in features.
