iOS 18 mail won’t download yahoo mail in background until I open the Inbox

Indeed, but this is general information. That doea not answer the fact that the mail app does not fetch email in ios18 as it did in previous versions. I have the same issue and all settings are just like before updating to ios18. The issue lies with the maill app not something else. I have several other email accounts also set to fetch and they work properly. The issue is only with yahoo accounts…

Did anyone else see the fact that when on wireless and charging, the yahoo accounts work perfectly fine? At least for me they do, everything is being fetched and downloaded as usual, but only when on wireless and charging. So this is the issue, I believe that the app is in some kind of low power mode (the phone is not) so this is what Apple needs to fix…

I tried, but it's still not working for me, irrespective of being connected to WiFi or being in charge mode. Only way to get the email is via the Yahoo Mail app. Last update in Apple mail is like 18 hours ago. When Mail is open, it goes into a frantic loop of "checking mail" "updated" "checking mail" "updated", without actually being able to download anything.

Again, this is just for my Yahoo account, all others work fine.

Email - Fetch vs. Push Differences

Email clients, such as the Mail app on iOS devices, use either Fetch or Push to retrieve new emails from email servers. The primary difference between these two methods lies in the initiation and timing of email retrieval.

Fetch

• Initiated by the client (email app): The email app periodically connects to the email server to check for new emails, downloading them when available.
• Timed-based: Fetch intervals can be set, such as every 15 minutes, 1 hour, or daily, depending on the email client’s settings.
• Slower response time: Fetching emails can take longer since the client needs to actively connect to the server and request new emails.

Push

• Initiated by the server: The email server proactively pushes new emails to the client (email app) as they arrive, without the client needing to actively request them.
• Real-time notification: Push allows for immediate notification of new emails, as the server sends updates directly to the client.
• Faster response time: Push eliminates the need for the client to periodically check the server, reducing the time it takes to receive new emails.

In summary, Fetch is a client-initiated, timed-based approach, while Push is a server-initiated, real-time notification method. The choice between Fetch and Push depends on individual preferences and email usage habits. Some users may prefer the immediate notifications of Push, while others may prefer the more controlled, batched approach of Fetch.

Same thing, absolutely.

ok with other counts or providers, but doesn’t work anymore with yahoo mail on iOS 18 (still ok on ios17 from another iPhone), no mails downloaded in the background.

Indeed, I always used and still am using fetch at 15 minutes for all accounts and the only ones not working properly are the Yahoo ones…

See if you settings are either Push or Get in your. In the page that lists all your email accounts look at the very bottom "Fetch New Data". Mine are iCloud is Push, Gmail is Fetch, Hotmail and Outlook are on Push

Same issue here. Used to work fine before IOS18 upgrade. Other email accounts (Gmail, outlook, iCloud) working fine. I tried to delete and add back the account, change settings from Fetch to Manual and vice versa, to no avail.

I also tried deleting the account and adding it "manually" (i.e. without adding it as a Yahoo account, but rather specifying IMAP server settings, but the result is the same...

Having the same issue on my iPhone 15 Pro Max and my iPad. Ever since the iOS and iPadOS 18 updates my Yahoo! mails no longer download in the background. I have the same settings as I had with the previous iOS version, but I can only get my emails if I open the mail app. All other accounts work fine, but Yahoo! does not. When will this be addressed?

There is actually a setting for this particular behavior. If your fetch settings are set to “automatic”, it will only download over WiFi and when connected to power. The issue is that if your fetch settings are set to 15, 30, or 60 minutes, it functions as though you’re doing a manual fetch.

I tried many of the fixes in this thread and the one that worked for me was plugging in my phone. I had deleted my Yahoo account, and re-added it. My inbox was empty, but as soon as I plugged into power it downloaded my entire Inbox. Definitely a bug on Apple's part here as it continually is "Connecting", knows how many unread emails are in the account, but never actually downloads them.

Note to test this you can see the phone will Check for mail when plugging in and out power.
