Mail is slow since updating to iOS 15

"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!"

Wowzers! -- So, when is the last time you cleared it? How long have you had this device? It would take years for all of that to be the case, if Temporary Internet Files took that much data.

I have the same problem and it started right after upgrading to iOS15. In my case, even when I refresh email it does not fetch new email. Eventually(hours later) it downloads more, but it is always behind. I was able to mitigate this by reducing the amount of email kept on the ios mail app from the default of one month to 1 week. I have more than 100GB free on the phone, so it is not a space issue, but that certainly helped. At least for now.... and it took a while to catch up after the change.

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.

I had the same issue. Mail loaded daily quickly but loading each message was terribly slow and almost not happening, especially mails with attachments.

Went to mail settings and disabled privacy settings for protect mail activity and turned off block all remote content while keeping hide IP address on.

Now it works but loading is still a bit slower than before the upgrade.

Looking forward to Apple for an update on this.

I have the exact same problem on my iPhone 12 Max Pro. Only started after the update to iOS 15. I've deleted, re-added the account, checked storage, fooled around with Mail settings, network is fine..........so I switched to the Google Mail app since I use mostly Gmail anyway, and yes, I have sent a "bug report" to Apple about it. They need to fix this!

Same problem here as well! Stucking to a date earlier or no email show so long times make me restart the email app but not helping! Got bored of this problem, it is frustrating to search for an email or checking the latest one received! Or read/unread marks mixed up!

I’ve got an iPhone 12 Pro, so not too old but I’m having the same issue. I’ve tried everything that everyone has suggested including deleting the app & reinstalling, I’ve even done a complete re reset. None of it makes any difference. It’s an ios15 issue and anything else is just apple playing for time to sort it out without being seen as responsible.

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 the same problem. I tried every fix suggested and nothing works.

it is an update problem, I have an iphone i haven’t upgraded and zero problems. I have checked my mail changing to cellular data, hoping it was my router, and I was wrong.

Your sent and other mail stored in your device is still there, I can see some listed occasionally. But cannot do anything with it.

contact Apple, great idea, let your voices be heard. It is a bug in their update, no question. Or an oversight, who knows.

I had this problem too. It has to do with the increased security that iOS 15 has.

Here's what I did that worked:

Settings> Mail>Privacy Protection. Then turn off the IP Address protection. The ONLY slider that's green on my phone is the one that says Protect Mail Activity. At that point all the other options are gone.

When I did that, my email opens up just as fast as it ever did.

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.

This is one issue have complained about several times .it actually started with IOS 14. we had a lot of hopes that IOS 15 was to sort out the matter. Unfortunately it's still the same. When you have the old models of iphone's running 13.0 and below. You realize its working fine. And wonder why apple keeps on releasing new updates without considering first the challenged being faced by the clients.

We spend so much to purchase the phone yet the services are becoming very poor. soon we start moving back to Android unless this issue is addressed.

This worked for me but it’s probably too simple to work for everyone….

Settings > Mail > Accounts > Fetch New Data > Automatically - (Changed from “Every 15 Minutes”)

Now, when I manually check, it is almost immediate just like before the upgrade (and I have 10 mail accounts). The “Checking for Mail…" process used to take up to 20 seconds whether i had mail or not.

NOTE: Not so sure if it is the option I chose or just the change from one to the other that triggered this fix for me.

There is no solution to this and all fixes are coincidences. When you close and open Mail app with swipe up on your iPhone, first mail check will take long time. Period. It has nothing to do with any of the privacy features apparently.

(vitapom) This problem is not related to “first mail check”. Any time you check for mail whether it’s first time the app is opened or any subsequent check, the process could take a long time (up to 20 seconds for me). The change I made triggered a fix for me; I don’t necessarily think it is the fix but seems to have triggered a change that fixed this problem for me. Period.
