Obviously, it depends on how fast and what task.

  • Internet browsing
  • LED torch/flashlight
  • Watching video (depends on selected quality)
  • Stand-by
  • Always-on display
  • Writing text
  • Music playback
  • Music playback over headphones or bluetooth
  • etc.

I often asked myself: How long could a phone do these tasks with the power from one second (or 10s or 1m or 5m) of fast charging?

Hrm . . .
But thanks for testing.

It's still good that a phone that's over 10 years old still functions to some extent.
