Battery Level Prompting via Display Mode Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often ignore battery level prompts on electronic devices, especially when in full-screen mode, leading to poor prompting effectiveness.
Innovation Solution
A method and apparatus that adjust the display mode of an electronic device to enhance battery level prompting by changing attribute parameters in full-screen mode or enlarging status bars in non-full-screen mode, ensuring users are alerted to low battery levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery level is prompted using traditional status bar marks or text prompts, then the implementation is simple, but the prompting effect is poor and easily ignored by users
Solution Approach 1:
The patent applies color changes by displaying the battery level prompt in yellow color on the current interface. This visual differentiation makes the prompt noticeable without requiring complex system interruptions, thereby improving reliability while maintaining simplicity.
Solution Approach 2:
The patent transitions from traditional status bar prompts to displaying battery level information directly on the current interface dimension. This dimensional change ensures the prompt is visible regardless of whether the status bar is obscured, improving effectiveness without adding mechanical complexity.
2Reliability
If the status bar is enlarged to improve battery level visibility, then the prompting effect is enhanced, but the display area for other content is reduced
Solution Approach 1:
The patent applies local quality by making only the battery level prompt area visible and prominent, while leaving the rest of the display area unchanged. This localized approach ensures battery visibility without sacrificing overall display space for other content.
Solution Approach 2:
The patent uses partial action by displaying only the essential battery level information (e.g., 'Battery level: 20%') rather than enlarging the entire status bar. This partial display achieves the visibility goal while minimizing impact on display area.
3Reliability
If the electronic device interrupts the current operation to prompt battery level, then the user attention is captured, but the user experience is degraded
Solution Approach 1:
The patent implements periodic action by checking battery levels at intervals (e.g., every 5 minutes or when below threshold) and displaying prompts only when necessary. This periodic monitoring captures user attention when needed without continuously interrupting operations, maintaining ease of use.
Solution Approach 2:
The patent uses an intermediary approach by displaying the battery prompt as an overlay on the current interface rather than interrupting the application. This mediator layer delivers the message without disrupting the user's workflow, preserving ease of operation.

AI summary
A method for prompting a battery level is provided. The method includes: obtaining a display mode of a current interface of an electronic device when the electronic device is in an uncharged state and a battery level of the electronic device is less than a first preset battery level. The method further includes performing a target adjustment operation based on the display mode of the current interface. The target adjustment operation is associated with the display mode of the current interface. The display mode of the current interface includes a full-screen mode or a non-full-screen mode.
