Z3 Battery Life Oddities

2 days ago was the start of another charge cycle, and I was hoping that I'd eek out maybe another day if I bothered to turn off the wifi connection during the day as I only have a wifi connection at home.

Oddly enough, the battery kept draining even though I only turned on my phone quite rarely.

Today, I just left my wifi connection switched on, so that it'd be hunting for it the whole day. Surprisingly, the battery life dropped only by a few percent over the day. Why the hell is that? One would think not searching for the wifi every few seconds would save lots of battery.

Well I guess I'll leave it on for now :)
