Mail is slow since updating to iOS 15

I have the same issue, thought it was my email provider, but recently have tried a few things and have noticed the following :-

1. I turned off all settings below ‘Settings’ - ‘Mail’ - ‘Privacy Protection’ and this made no difference.
2. If I check email on a non-Apple program such as Outlook it is fine.
3. My email tends to work fine for the first 3-4 emails but then grinds to a halt on the 5-6th email saying “Loading” for about 20 seconds, this can be on emails I’ve previously already read also.
4. If whilst an email says “Loading” if I disconnect WiFi or if already disconnected reconnect it, the changing of the network makes my email kick in again for 3-4 emails, but then stops again.
5. If I swipe up and end the ‘Mail’ program and then reload it, it works again for a while, but again after reading a few emails I get stuck on “Loading’ again.
6. Having to do the change network fix or end Mail is not a workable solution.

I have an iPhone 13 Pro Max 256GB, 165GB of free space. My iPad Pro M1 does exactly the same. Both are on the latest IOS version, 15.4.1 currently.. My email is connecting via SMTP. This issue is very frustrating, I rely on my email constantly..

I have been having the same issue as posted before. This is absolutely ridiculous. Are use my phone for work and need to receive my emails exactly when they are sent to me without delay. It is very important for me to process reservations.

not sure if this will help someone, but I have also downloaded the Gmail mail app. Trust me, we shouldn’t have to I’ve been using the Mail app for the past 10 years with no issues until the iOS updates. It’s funny how your phone updates by itself whether you wanted to or not. You paid $1000 for the phone and you don’t even have control over it.

now that I have the Gmail app at least I know I’m receiving an email then I can go onto my Mail app and refresh it and receive the email which again we shouldn’t have to do. Sometimes it takes several minutes for the email to show within the mail app when I have already received a notification from Gmail.

i’ll say it again, we shouldn’t have to do this but maybe this will help somebody as a failsafe

I just gave up on using the Apple mail app and downloaded the gmail app. I’ll switch back to Apple mail, once they fix the problem. The gmail app is lightning fast and allows you to add other email domains.

So I got my emails working, but only by switching off wifi. It’s rather pathetic that Apple increasingly make us rely on workaround for the most basic functions. I have to switch off wifi to get emails on my iphone. On my ipad pro, it’s just not worth working with emails. Expensive equipment, that can’t do the basics.

Is there a chance just deleting the Apple Mail App (if possible) and reinstalling it may fix this?

I am experiencing the same issue since updating to iOS 15, not only on my iPhone but my iPad as well.

I have double checked my password, deleted the account and added it again but it is still the same.

"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 tried all of the solutions above. Mail is still extremely slow to load on my iphone Xs after update to ios 15. This is my work phone and i need it to load email quickly like it did the minute before i updated to ios. This has to be a known issue. What is the solution please? If there is none, then please let me know how to revert back to the previous version of ios which worked just fine for me.

Correct. You have not you have received any helpful advice from Apple here. These are user-to-user forums. We are all volunteers. It's all based on prior experiences on troubleshooting this. So, if you wish to speak with Apple Support, do so using this info:

Apple Contact Info:

• Proceed from there, as necessary

Why the Wait:

Phone calls are taking a bit to go through at the moment, due to lots of calls. With the Coronavirus Pandemic, many are at home at the moment, with much time on their hands to contact Apple. So, just stay on the line, and you will get through :)

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.

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.

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.

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.

Same frustrating issue. Open email app and all I see is a white screen with arrows on the right waiting for the email to appear. Takes forever to see the emails. Often have to close the app and re-open to see email. I had no problems prior to iOS15.4 and have not changed any settings after installing iOS 15.4. There is some issue with iOS 15.4.

iOS 15.4.1, iPhone 13 Pro.
