NULLUN USE CASE · BATTERY STATE
Create Custom Battery States for Android Screenshots
Nullun can prepare low-battery, charging and warning-state presentations for Android screenshot mockups, tutorials, app demos and UI examples. It changes the visual scenario, not the phone's physical battery.
Show the state your scenario needs
A battery-saver tutorial needs a credible low-power state. A charging walkthrough needs a different presentation. A UI case study may compare normal, warning and lock-related battery states without waiting for a device to enter each situation.
Nullun makes these states part of the screenshot composition so they can be reviewed before export.
Designed for demos, tutorials and mockups
The feature is intended for legitimate visual communication: explaining an interface, demonstrating a state, preparing documentation, designing a mockup or keeping app presentation assets consistent.
It should not be used to fabricate evidence, impersonate a system event or intentionally mislead another person.
Combine state and percentage carefully
A state becomes clearer when its percentage matches the story. Use the custom battery percentage for screenshots guide to choose an exact value, then review the whole bar for consistency.
For carrier, signal, LTE or 5G, Wi-Fi, app name and notification details, use the broader Status Bar Editor for Android workflow.
