Now I'm curious as well. I use it often, but not for that long each time. I know it gets hot after a while and it drains the battery.

How long is it supposed to last?

LEDs should last for tens of thousands of hours. There may have been a manufacturing defect in OP's case.

This isn't necessarily true. LEDs are capable of running for years, but not all LEDs are designed this way or are operated this way. An LED in a given application can die quicker if:

  • the LED manufacturer cheaps out
  • the phone manufacturer runs the LED at higher current for more brightness
  • the phone is poorly designed, allowing the LED to heat up
  • the phone is exposed to significant heat and/or the LED is covered while used for a long enough duration
