What is INP by device brand
INP by device brand shows how Interaction to Next Paint (INP) varies across real-world hardware families — such as iPhone 14s, Pixel 7s, Windows laptops, or older Android phones.
Unlike general categories like “Mobile” or “Tablet,” this view exposes how responsiveness is influenced by CPU speed, memory limits, OS behavior, and even browser implementation quirks tied to specific devices.
This lens is crucial for spotting brand-specific interactivity bottlenecks, like laggy taps on older Android phones or delayed clicks on low-end Chromebooks.
Healthy INP by device brand sample
Should you worry
In a healthy state:
All major brands show green INP values, with maybe some expected variation between budget and premium devices.
iPhones and high-end Androids often perform best, thanks to strong hardware and efficient input processing.
Desktops tend to stay fast unless burdened by long main-thread tasks or legacy software.
If even your slower or older device brands are in the green or low yellow, you're doing a great job of minimizing input delay across the board.
Unhealthy INP by device brand sample
When certain device groups consistently underperform, it often means:
Android devices suffer from JS-heavy pages, complex event handlers, or unnecessary animation work.
iPhones may lag if touch events are blocked by long tasks or if poorly optimized libraries slow Safari.
Windows laptops may show bad INP on low-power devices or when CPU throttling kicks in.
Older brands in general tend to amplify problems that modern hardware can mask.
INP gaps by brand are often your canary — revealing when your UX depends too heavily on high-end device specs.
Resolving unhealthy INP by device brand
Go-to action plan to resolve an unhealthy INP by device brand:
Ask Uxi to analyze your INP by device brand values and suggest improvements.
Filter down to the slowest devices and pivot to INP by interaction type or INP by element to find which events are the bottleneck.
Simulate INP of the suspected lens to see if fixing it will resolve the INP by device brand. If yes, this is where the resolution focus should be.
Use an automated INP optimization tool like INProve to improve your INP by device brand values.
Once you’ve improved INP, set an alert to be the first to know if it starts worsening again.
