Mail is slow since updating to iOS 15

I have been experiencing the same since updating to iOS 15.6.1 and others at my firm. Does Apple have any recommendations? It seems to be more widespread if multiple users are reporting the same.

It is not an issue with storage available as I am using 45.2 GB of 128GB; I am mostly connected to Wifi as I work from home. I have performed all the basic troubleshooting as well as removed my firm's MDM ( MobileIron ) and re-installing it, and it's still the same. It is sporadic in that my email seems fine at times but is mostly delayed in loading when I try to open the new email.

Couldn’t get mine fixed so bought a new 14 phone to try the reset and restore fix, guess what brand new phone, iOS 16.0.1 still broken, this is ridiculous, just get it fixed guys, I’m loosing out on important emails…

Is Apple going to address this issue that is obviously related to the last 2 software upgrades? Mail worked great before the update…now it’s incredibly slow…mostly hangs on updating mail. I have 200gb of free space, cache is clear, I have deleted and reinstalled the mail account, I have consulted every tip and trick….nothing helps….

Is Apple going to do anything to rectify the problem that they have created with the last 2 software updates? Or does Apple just not care? Email worked really well before the update…I have removed privacy settings, reinstalled email multiple times, cleared network settings, reset network settings, etc…etc…etc… I am on fiber optic network with very fast settings…search functions are normal, however email is ridiculously slow…like taking 5 minutes to download one email. I can go straight to my services site but as it is designed for a computer and not a smart device all functions do not work as well. I would prefer that Apple fix their issues and quit making garbage suggestions that don’t work.

Slow Email on both my iPhone XS Max (16.1.1) and iPad Mini 4 (16.1.1). Only affects my Gmail account (Spectrum, Live, iCloud Accounts perform quickly). I tried disabling Privacy Protection and uninstalling/reinstalling the Apple mail app with no improvement observed. Gmail updates when fetched on schedule but manually attempting a fetch by dragging down on the Email header list results in a long displayed "Checking for Mail..." message in the mail app.

It seems that Apple just doesn’t care….fine, they’ve been on top for awhile….if they’re okay with losing their customers and going down the tubes that’s okay with me too…too many other options out there. Let the software people run the company into the ground….they obviously don’t care about us…the people that buy their equipment and pay their salaries.

My mail for my email on one phone is 10 hours behind and counting. The other runs a couple hours behind on average (last few weeks).

it is so bad, that I feel like I really need to go to Gmail, to securely get my stuff in time. This has been going on for several weeks, the slowness part.

My phones are all updated and current.

You are welcome.

Thank you for the quick reply.

Never mind, it is better, but starting to fall behind again. It will say "updated just now" when I refresh, but it won't download all recent mail.

I have the same experience. Mail app reinstalled and still iOS 15 renders the mail app non functional on iPad.

My new iPhone 12 has come to a stop while downloading emails. Only after the update to IOS 15

This does not work and is not a solution.

I am also seeing this issue. iPhone 11 Pro. iOS 15.1 - mail does not load as quickly as it did in 14/prior. Occurs on wifi and cellular data.
