I’m also upgrading from a xs max to 12 pro max, to me it’s a decent upgrade, when I had the 12 for 1 day i noticed the speed improvements straight away, the A14 is a beast, apps launch quicker, keyboard felt way more responsive, Qualcomm modem was a big improvement over the intel modem.
Looking forward to using night mode, ultra wide camera, better low light camera, slightly larger screen is a bonus as well, extra 2 gig ram, no more finger prints on the back of the phone thanks to the matte finish.
Glad they went back to the iPhone 4 design.
The 12 series is a decent upgrade for anyone upgrading from a xs and lower.
Can’t wait to get mine.
