Am I the only one that feels in the view of trying to lower power usage this app barely works anymore? The amount of times I've missed critical emails then I plug my phone which wasn't anywhere near red battery in at midnight and suddenly Mail kicked in to fetch 20 or so emails including important ones from 12 hours ago.

This is using just standard email via IMAP not Google or whatever.

Basics across the board on modern iOS are nowhere near what we had a few years ago.
