I have noticed they don't stay on very long. It is sometimes annoying. If they could just have them lit up for a little while longer it would be very helpful.
I don't need them on constantly.
Also, I had a Lumia 800 for a while and those buttons would stay lit for a lot longer until Nokia pushed out an update and one of the things they changed was a shorter time for those buttons to stay lit and I couldn't figure out why because it was so much better before that.
