I have my 3DS in my coat when I walk to work, to get play coins and catch any potential street passes on the way in. I'll usually leave it sitting in my coat while I work, so I can take it back out for more at lunch and again at the end of the day.

However it's not clear whether or not I'm using up a lot of battery this way, especially as it's left sitting in my pocket for hours while I just work. Does anyone have any information on how power hungry standby/streetpass are?

According to this IGN Article, all versions the 3DS and the 2DS should have a battery life of about three days when in sleep mode.

Here is a simple chart comparing all the major differences between the three major Nintendo 3DS models:

 Battery Life Nintendo 2DS Nintendo 3DS XL New Nintendo 3DS XL 3DS gaming: 3.5-5.5 hours 3-5.5 hours 3.5-7 hours DS gaming: 5-9 hours 6-10 hours 7-12 hours Sleep Mode: 3 days 3 days 3 days
