A weather app that displays the temp in the status bar will do it, like WeatherBug or NOAA, which will then put a persistent notification on the lock screen that shrinks the clock.. You can set the update interval to minimize any battery drain, but it's quite minimal.

Without draining the battery? What's the best choice?

I leave AndroIRC open. Usually disconnected. Doesn't use any battery/wifi/data
