For some reason my 3DS battery life seems shorter to me than it used to. Over two weeks ago I had my 3DS in sleep mode and occasionally played streetpass games for most of the day, where I think it had just over two bars left before I recharged it, but last saturday it was nearly out of power after playing and being in sleep mode for roughly the same amount of time. I might be imagining things but what do you think could have happened? I haven't changed any of my settings so I know it's not because of that. Could it have been because of the new firmware update? I've heard rumors how certain 3DS games drain the battery faster but that seems doubtful.
