I previously had a 2010 RX but I don't think it was a problem on that year of car. I do remember it being an immediate problem with my current Impreza (i.e. having to recharge the battery before I could start it one morning) which p1zzed me off. Battery too small ( 65Ahr as designed) for all the electronic junk on the car. The current fob has a ridiculously long range, 80 to 100 metres which I don't think was the case with the older car.
I wouldn't worry about the it if you don't have a problem, but my understanding of the 2019 system is that unless in 'sleep' mode', the car and fob are actively looking for each other. I believe they communicate more often if in range of each other. I also find it very easy to leave the new car unlocked if I'm still in range and put the keys in my pocket and accidently press the raised unlock button !! I am happy to be corrected if someone has solid evidence of it being otherwise.
