Funny, I never noticed any difference. For example: This winter I was using my new Asus Zeofone 3 in airplane mode (No cell reception, but had GPS turned on to high accuracy) tracking my ski day on one of the interior mountains in a white out/blizzard,50 kmh winds, in temperatures going down to -26c, so the conditions couldn't possibly get any worse... The phone locked on to a signal relatively quickly (within 30 seconds), and subsequently, I had my handheld GPS tracking the same stats for comparison sake, took about the same time to lock on to a signal, and both tracks were literally identical when overlayed in google earth.
Perhaps GPS technology in phones has changed/improved over the last few years.
Note: Phone I have is an ASUS Zenfone 3. According to maunfacturer specs, has A-GPS, GLONASS.
