22. Prioritize a mobile-first approach

In the era of smartphones (62% of global internet usage is mobile), embracing a mobile-first strategy is helpful for crafting streamlined, light, and efficient digital products. Less space on the screen means less content and fewer features, which directly leads to less data transfer, less energy consumed, and a better user experience because your users can solve their needs faster.

If your service is currently used primarily on web, you need to do some additional research. Don’t assume that users do not want a mobile version. Current usage could be skewed due to survivorship bias. However, if your research shows that your service is most appropriate for web, do not superfluously build a mobile app.
A mobile-first strategy can ensure that the user experience is optimized for mobile devices, while curbing the necessity for purchasing newer devices and contributing to e-waste. Mobile first is a great approach for many B2C applications and some B2B applications.

• 🧑 Streamlined product performance, exemplified by faster load times

• 🧑💰 Enhanced user experience leading to improved conversion rates and overall satisfaction

• 🧑💰 Reduction in maintenance costs, reflecting efficient design and execution

Testing your design with older devices, operating systems, and slow-speed connection is best. This will make your experience more inclusive and accessible and help curb the necessity for the purchase of newer devices and contributing to e-waste. More in Avoid obsolescence tactics.

Designing for mobile isn’t just good UX—it’s also good for the planet. Optimize continuously for mobile performance to reduce data usage, energy consumption, and device strain. Use consistent, adaptable design patterns across screen sizes to avoid duplicate work and digital bloat. Aim to create one efficient, inclusive experience that works well everywhere—minimizing waste and maximizing impact.
