I have an unrooted stock Xperia Z Ultra, should the LED turn off when the battery is fully charged? I got an Xperia Z Ultra unrooted and still running on the stock ROM (Android Lollipop 5.1.1). My question is, when I'm charging it and the battery reaches 100%, is the LED indicator light supposed to turn off to notify that it's fully charged? So I'm kinda asking what behavior I should expect from it.
User guide doesn't say it should be switched off on full. Expected behaviour below


  Battery notification light status
  
  Green   The battery is charging and the battery charge level is greater than 90%
  
  Red     The battery is charging and the battery charge level is less than 15%
  
  Orange  The battery is charging and the battery charge level is less than 90%


Edit: If the LED turned off, you wouldn't know whether it is fully charged or charger isn't connected, color coding this way makes sense
