Hello everyone, for almost the past two years I have owned the XS MAX. I upgraded to it from the 7 Plus and I found the battery life to be much better than on the 7 Plus. I know that with the 12 Pro Max you can get up to 5 hours longer than the XS MAX. For those of you who have upgraded from the XS MAX to the 12 Pro Max has the battery life been substantially better? I am a heavy user but I can change some settings if I wanted to become a light user.
