Ember mug reset, is it really just the blue/yellow/red LED cycle?

forgot to mention. On iOS you have to go into bluetooth settings and select "forget device" before you reset the mug.
 
you're overthinking it. Hold the button down. See red. Let go. Its a one step process, hold it down again if its not working.
 
Fwiw I had one of these that would not reset. Eventually found out the button itself was faulty. Replaced it through warranty since its under the year mark.

see this is why I don’t play with them. Buttons break. Dies charging. Battery swells. For the price of one ember I got a stainless thermos that has lasted me 6 years and counting.
