Mobile performance directly impacts user retention. Even 1-2 seconds of delay can significantly hurt conversion.
Startup performance
Deferring non-critical modules on initial load improves perceived performance.
Post-splash blank time should be minimized and users should get visual feedback at each step.
List and image optimization
In long lists, virtualization reduces unnecessary re-render costs.
Proper image sizing and lazy loading improve both memory and network usage.
Network and offline strategy
Request batching, cache policies, and retry strategies keep UX stable under network fluctuations.
Offline-first design keeps critical workflows uninterrupted, especially for field teams.
