I recently had to downgrade my phone for a few days to an original iphone SE, 6s internals basically A9 chip. It was noticeably faster in the ux than my current A13 phone. Makes no sense to me. I type “cal” in spotlight on the A9 phone and I get calendar returned almost instantly. I do the same on the A13 and there’s a few seconds of delay before any results show, but get this I can’t even get calendar to return, only calculator and google calendar that isn’t even installed. So considering that new phones aren’t always faster than the old ones where it actually counts (the ux), how are these newer gen ipads fairing? Do they actually feel like upgrades?
