Speed Up Gmail on iOS

I notice a frustrating delay every time I open or read an email that comes through my Gmail account in the Apple Mail app on my iPhone and iPad. Other apps feel snappy, so I’m convinced the issue is tied to the way Gmail syncs with Apple Mail rather than my network connection. I need a specialist who understands the inner workings of Gmail IMAP, iOS Mail settings, and the typical bottlenecks—whether that’s push-vs-fetch schedules, oversized message caches, background app refresh quirks, or hidden Google account toggles. The end goal is simple: mails should load instantly (or as close to it as possible) when I tap them. What I expect from you: • Diagnose why messages open slowly in the Apple Mail app connected to Gmail. • Walk me through the exact settings or advanced tweaks—both in iOS and in the Gmail web interface—that will optimise sync speed. • Provide a concise set of steps I can repeat on any future device. • Confirm the improvement with a quick follow-up test once changes are applied. If you prefer to guide me over a remote session, that works; if detailed written instructions are faster, that’s fine too. As long as, by the end, tapping an email no longer feels like waiting in line, we’re done.
