The perceived usefulness and psychological factors, rather than purely technological obsolescence, are the primary drivers of a smartphone's in-use lifespan. This user-centred design research insight is drawn from a 2025 study published in Sustainability. Using Literature review and conceptual modelling, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Focus on designing for long-term user satisfaction and perceived value, as these are stronger determinants of product lifespan than technological obsolescence alone.
User Perception, Not Just Technology, Dictates Smartphone Lifespan
The perceived usefulness and psychological factors, rather than purely technological obsolescence, are the primary drivers of a smartphone's in-use lifespan.

Key Findings
- 01Smartphone obsolescence is driven by both technological advancements and psychological factors related to user perception.
- 02The 'in-use lifespan' is defined by when a user finds the device still useful, not necessarily when it's technologically outdated.
- 03User perception and psychological attachment significantly influence the decision to replace a smartphone.
Application
Design takeaway
Focus on designing for long-term user satisfaction and perceived value, as these are stronger determinants of product lifespan than technological obsolescence alone.
How to apply
When designing new electronic devices, consider features and user experiences that foster long-term attachment and perceived usefulness, such as software updates that maintain functionality, durable build quality, and intuitive user interfaces that remain relevant.
Project actions
- 01When researching user needs, explore not just functional requirements but also emotional and psychological aspects.
- 02Consider how a product's design can foster a sense of longevity and continued value for the user.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Synthesizes a broad range of existing literature.
- +Provides a conceptual framework for understanding product lifespan beyond technical limits.
Limitations
Directly measuring 'perceived usefulness' can be subjective and difficult to quantify without extensive user studies.
Reliability & validity
The reliability of the findings depends on the quality and consistency of the reviewed literature. Validity is enhanced by synthesizing multiple sources but is limited by the absence of direct empirical testing of user perceptions.
Think critically
To what extent can designers truly influence psychological factors like 'desire for novelty' through product design alone, versus external market pressures?
Design Principles
"Design for perceived longevity by fostering emotional connection and sustained utility."
Understanding the user's subjective experience is crucial for designing products that last longer. Designers and manufacturers should focus on maintaining user satisfaction and perceived value throughout the product's lifecycle, not just on initial technological capabilities.
What This Means for Your Design
People keep using their phones for longer if they still feel like they are good and useful, not just because the newest technology is out.
How to use in your project
- 1.This research can inform the user research phase of a design project by emphasizing the importance of subjective user experience.
- 2.It provides a framework for analyzing why users might discard a product prematurely, guiding design decisions to mitigate these factors.

Paragraph starter
This research indicates that the in-use lifespan of consumer electronics is significantly influenced by user perception and psychological factors, rather than solely by technological obsolescence. Therefore, design strategies should aim to foster long-term user satisfaction and perceived value to encourage extended product use.
