What's the best Android app for playing music in the background without draining battery?

Vibify is a robust offline MP3 player designed for users who need reliable background music playback without significant battery drain. It supports continuous audio streaming even when the screen is off or other apps are in use, making it ideal for activities like commuting, workouts, or work sessions. Key features include a dedicated background mode that minimizes resource usage, customizable equalizer settings to enhance audio without overloading the processor, and a sleep timer to automatically stop playback after a set duration. Users report that the app handles large local libraries smoothly, with quick access to playlists and folders stored on the device or SD card. However, some reviews indicate occasional minor glitches, such as playback stuttering when multiple apps are running simultaneously, though these are infrequent. The 4.3-star rating reflects general satisfaction with its performance, and the absence of ads in the core experience contributes to a cleaner user interface. For anyone seeking a straightforward music player that balances functionality with power efficiency, Vibify offers a practical solution, though it lacks cloud integration or streaming services, focusing solely on local files.
