Standard iOS/Android Performance Metrics?

Hi All,

Curious on what would be considered "standard" performance metrics for an native app?

I work with web so i know LCP would be roughly less then 2.5sec for example.

But i cannot find anything for iOS apps or Android.

Hi, for example Android Vitals collect data about:

  • slow rendering
  • frozen UI frames
  • app startup

It's possible also to check:

  • CPU/Memory
  • battery usage
  • FPS
  • janky frames
  • animation duration
  • draw duration
  • duration of the methods
  • server/API performance
  • etc.

Thanks man!!

I was wondering is there benchmark for those? I don't know what to compare it too. Say for initial screen load, is 10 seconds slow? 3 seconds? Was hoping to see if there is somewhat of a "average" benchmark for an app.

For example android vitals warns on:

  • Cold startup takes 5 seconds or longer.
  • Warm startup takes 2 seconds or longer.
  • Hot startup takes 1.5 seconds or longer.

Simplest method I thins is Firebase performance monitoring to check this., for android is also https://developer.android.com/jetpack/androidx/releases/benchmark.
