In the cooler part of the year (it's now 14 degrees C out, or around 57 degrees, and most homes in HK are not insulated or heated), I can leave leaves in my pot for two days without any issues. Sometimes a long overnight brew can get you the last bit out of the tea before you clean your pot out, so I do this fairly often, but not as often as I used to.
That is a good point to keep in mind. My house is overly-warm. My leaves are really just as good the next day as the first day. It seems so wasteful to discard them.
