Mail is slow since updating to iOS 15

I am not sure why Apple has not provided helpful information; however, I followed someone’s suggestion after having the same problem since install of IOS15 and following everyone’s resolve by backing up my iPad to the cloud following these steps.

1. go to ‘settings’
2. go to ‘general’
3. click on ‘Transfer or Reset iPad’
4. click on ‘Reset’
5. Restore from iCloud backup
6. or by following https://www.itproportal.com/features/how-to-restore-a-backup-from-icloud/ This is an extremely useful post.

Good Luck, and I hope this is helpful.

I was annoyed with the same dilemma for months. This worked for me, as another user suggested.

1. Delete all mail accounts (hopefully you know your password or can find them in the password listing under settings.
2. Back up your iPad to the cloud.
3. Reset the iPad to original, as though you were going to start with a new iPad. (When you open settings, there is a search at the top directly under the Settings title; type in Reset, and click on the first link that appears). Power down, and restart.
4. Restore your backup from iCloud.
5. Reinstate your email accounts. All of your mail will come back.
6. ‘Best of Luck.

Hi-Just lost my **** with this and after a web chat, got a call back from AppleCare.

If you have a vpn on your phone, disable it, switch your phone off, switch it back on, give it two minutes, switch on your vpn and it seems to work. Not sure how long this fix will last though! Watch this space.....

I tried all of the suggestions mentioned in this thread with no luck. I found removing the mail app and then reinstalling seems to have worked. A problem I can definitely attribute to ios15.

"Mail is slow since updating to iOS 15: What is causing email to download so slowly that it has virtually stopped since updating to iOS 15?"

Remove/Add eMail Account:

Remove the eMail and then add it back. Perhaps it all needs to resync with the mail server.

Clearing Temporary Internet Files made a big difference. Mail is loading much quicker. Over 100gb of free space on the phone and iPad.

i still think it was snappier pre ios15.

thanks for the help though!

Thank you! This is the only thing that worked. It got so bad I switched to the Gmail app because I just couldn't wait for emails to load....it took forever. I already had Protect Mail Activity disabled, but it was the Hide IP address that did the trick. I had that enabled and turned it off.

I have also found that none of these fixes works for me.

It is obvious that this is a bug in 15.1 because of the workaround I have found. When I open an email and nothing happens (just the circle revolving) I close the Mail app and reopen it. Then the email is there immediately.

This only works for that email. So to read 20 emails I have to repeat the process 20 times, with each email - which is ridiculous! But at least it works (for me anyway) and I hope it might help others.

But it makes me sceptical that this is anything more than a bug on 15.1, rather than issues with network settings etc, since the data has obviously been downloaded as it is available immediately on reopening the app.

It would be nice to have a less patronising reply from Apple. After nearly 20 years (when I first moved from Microsoft) I am seriously considering moving back to MS because of the repeated problems with OS upgrades that don't work properly.

Hi, I was having the same issue, very slow loading from all email sources. I've turned off push and fetch and selected manual downloads for when the app is in use. At the moment new mail is loading and opening quickly again.

I also backed up my iPad to icloud and then factory reset from settings. After it reset I signed back in and restored from the latest backup. Seems to have fixed the slow Mail app issue…

Note, I did a backup to my MacBook but could not reset and restore from the Mac…strange. Anyway its working for now.

My latest problem with slow and unresponsive mail has gone on both my iPad (iOS 15.5) and new iPhone SE (iOS 15.5)

The fix for me was as simple as restarting iCloud on my iPad and turning it on and off a few times. And on my iPhone to turn it on and off a few times. If this doesn’t work for you I suggest setting up a call with Apple support so they can try and fix your problem.

Symptoms I experienced on my devices over a period of about 5 days: messages not being sent, partially loaded/displayed email page, slow response from the mail app.

After 5 or more months I Finally have a Fix on slow email! I followed someone’s suggestion by backing all to iCloud, completing a factory reset and restoring iPad with iCloud backup.

There is definitely something strange going on. After turning my iPad completely off and back on again Apple mail is working fine again BUT for how long?

Updated to iOS 15.6 and it fixed my slow mail problem.

After updating to the latest IOS 15 my email has been slow to open. I read where removing Gmail and reinstalling may fix it. People need to be warned that when you do that it my take an hour for all of your emails and folders to come back.
