Android 5.1 vs. Android 6.0: What's the Difference?
Edited by Aimie Carlson || By Janet White || Published on June 14, 2026
Android 5.1 focuses on improvements and fixes, enhancing stability and performance, while Android 6.0 introduces major features like Doze for battery management and app permissions control.

Key Differences
Android 5.1 Lollipop and Android 6.0 Marshmallow represent two stages of evolution in the Android operating system. Android 5.1 was primarily a release aimed at fixing bugs and improving performance and stability from its predecessor. On the other hand, Android 6.0 brought significant new features and enhancements over Android 5.1, focusing on user control and privacy, most notably through a revamped app permissions system.
With Android 5.1, users experienced refined user interface elements and improvements in connectivity, including enhanced Wi-Fi and Bluetooth support. Conversely, Android 6.0 Marshmallow introduced the Doze mode, a new battery management system designed to extend battery life by managing background processes more efficiently than in Android 5.1.
Another key difference lies in the handling of app permissions. Android 5.1 did not allow users to manage app permissions individually, whereas Android 6.0 introduced granular permissions, letting users approve or deny individual permissions to apps.
Security enhancements also distinguish Android 6.0 from Android 5.1. Android 6.0 introduced fingerprint support for device security and mobile payments, improving security measures beyond what was available in Android 5.1.
Android 6.0 offered improved storage management through the adoption of flexible storage, allowing for SD cards to be treated as internal storage, a feature not available in Android 5.1. This advancement significantly impacted how users could store apps and data, providing more flexibility than Android 5.1.
