Lost settings in cold weather, Battery needs replacement?

Again this year when outside temprature reaches -20C (-4F) and my car isn't used for nearly 24 hours, clock resets and comfort access doesn't work.

This happened to me last year too, but the car sat for a longer period of time (2-3 days). I noticed this time around even the tire pressure warning (red) came on and had to be reset.

Now when I set the time, it still lost the next morning. Is this a good indicator for needing a new battery, or just needs to be driven longer to regain charge?
