Google has officially released the second developer preview of the Android 16 operating system, bringing a number of improvements to app performance and experience. Among the highlights is the tech giant’s promise to improve battery life. Apparently, this was a common problem in the first test version.

Developer previews are known as builds of the Android operating system for software developers. They also allow developers to test and tune their apps for new system features. However, it’s important to note that these builds are unstable and not generally recommended for general use.

What does the second Android 16 developer preview offer?

Google has highlighted some key changes in the second developer version of Android 16:

• Battery improvements: The second preview focuses on settings that promise more efficient energy consumption and directly affect the autonomy of devices.
• Richer haptic effects: Thanks to new APIs for haptic effects, apps can now define more precise amplitude and frequency curves for vibrations, expanding the possibilities to respond to user touch.
• JobScheduler improvements: New introspection tools have been added to help developers better understand why certain processes are on hold or their history has changed.
• Adaptive Refresh Rate Enhancement: Introduced in Android 15, this functionality is now more accessible to apps, allowing them to more easily take advantage of dynamic refresh rates.
• Photo Picker with cloud search: Although not yet functional, the API for searching cloud media providers is already integrated. This novelty indicates that the feature will be enabled in future updates.

While these changes won’t have an immediate impact on end users, they pave the way for a more optimized experience on stable Android 16 versions.
