To illustrate this, let’s visualize the changes and improvements in the way the system conserves battery life.In Marshmallow, Doze mode is activated when the device is stationary and the screen is off.

The device enters a low-power state, limiting background activity.
Notifications are delivered in batches to minimize power consumption.
The system periodically wakes up to maintain network connectivity and synchronize data.

Nougat refines and enhances Doze mode, introducing more aggressive power-saving measures:

Doze mode is triggered even when the device is moving but the screen is off. This is a significant improvement.
The system utilizes a more aggressive scheduling algorithm for background tasks.
App Standby Buckets are introduced, categorizing apps based on how frequently they are used. This allows the system to prioritize power savings for less-used apps.
The “dozing” state is more aggressive, leading to even greater battery life improvements.

To represent these differences visually, consider a simple graphic:

Imagine two devices. One, representing Marshmallow, shows a battery slowly draining while idle. The other, representing Nougat, shows the battery remaining at a high percentage for an extended period, illustrating the enhanced power-saving capabilities. Visual elements could include a timer representing time elapsed, and icons representing background processes that are either active or dormant. The Nougat graphic would depict a more efficient use of power.

This illustrates the shift from a basic power-saving approach to a more sophisticated and dynamic system, optimizing battery life for the user.

Multi-Window Functionality

Multi-window functionality, or split-screen mode, is a significant feature introduced in Nougat. This feature drastically changed how users interact with their devices, allowing for true multitasking. Marshmallow did not offer native split-screen functionality.To visualize this, imagine a typical phone or tablet screen:

In Nougat, the screen is divided into two distinct sections, each displaying a different application.
The user can resize these windows, allowing for flexible multitasking.
A simple gesture, such as pressing the recent apps button and then selecting the “split screen” option, activates the feature.
Apps can be swapped between the top and bottom (or side-by-side) windows.

This feature dramatically improved productivity and convenience, allowing users to, for example, watch a video while simultaneously responding to emails, or taking notes while browsing the web. The multi-window functionality is a defining feature of Nougat, enhancing the overall user experience.
