This article will show you what to do ifย Gmail is not updating on iPhone. Although we cannot list every possible reason Gmail is not working on your iPhone, we can provide you with several universal tips about troubleshooting email on Apple gadgets.
Fix Gmail Not Updating on iPhone
To answer the question โwhy is my Gmail not updating,โ you need to understand how the default email client on iOS works.
Gmail App vs Apple Mail on iPhone
When troubleshooting Gmail sync problems on iPhone, one of the most important thing is to understand the difference between the Apple Mail app and the official Gmail app.
Keep in mind that the built-in Apple Mail app usually uses scheduled fetch intervals for Gmail accounts instead of true push notifications. Due to this, new emails may appear with delays depending on your Mail fetch settings.
In contrast, the official Gmail app uses Googleโs own background sync mechanisms and usually delivers emails faster and more reliably.
| Feature | Apple Mail | Gmail App |
|---|---|---|
| Push Gmail notifications | Limited | Yes |
| Uses iOS Fetch intervals | Yes | No |
| Google-native sync | Partial | Full |
| Label/category support | Limited | Full |
| Real-time Gmail sync | Often delayed | Better |
| Battery optimization impact | Higher | Lower |
Because of this, many folks prefer the official Gmail app because of its better reliability and faster syncing.
Checking Internet Connectivity
You need to check if your device has a stable Internet connection. Also, try to disconnect from your Wi-Fi and connect to another network, or try to use cellular data. As an option, try using VPN. In many cases, poor Internet connection can create a problem with syncing an email.
Verify Gmail IMAP Access
Note that Apple Mail connects to Gmail using the IMAP protocol. In case IMAP access is disabled in your Gmail account, then you may face that email syncing may stop working completely.
In order to verify IMAP settings:
- Open Gmail in a web browser.
- Go to Settings, then See all settings.
- Open the Forwarding and POP/IMAP tab.
- Make sure that Enable IMAP option is enabled.
- Save the changes.
Keep in mind that disabling IMAP may prevent Apple Mail from syncing Gmail messages properly.
Why Gmail Sync Is Delayed in Apple Mail
Unlike iCloud and Microsoft Exchange accounts, Gmail does not support native push sync inside the built-in Apple Mail app.ย Because of this limitation, Apple Mail retrieves Gmail messages using scheduled background fetch intervals instead of real-time push delivery.
The official Gmail app behaves differently. It it uses Google’s own push notification infrastructure and maintains direct communication with Google services in the background.
Because of this difference:
- Apple Mail may delay Gmail updates;
- Gmail app usually receives messages instantly;
- Battery optimization affects Apple Mail more aggressively;
- Sync timing may vary depending on iOS activity conditions.
This is one of the biggest reasons why Gmail notifications on iPhone often appear delayed when using Apple Mail.
Verify Mailbox Settings and Change Sync Timeframe
Unlike many third-party email apps, Mail does not push email from third-party providers. Instead, it fetches data every 15, 30 minutes, 1 hour, etc.
- Openย Settingsย and go toย Mailย >ย Accounts.

- Tapย Fetch New Data.
- Select a new fetching period from theย Fetchย list.

The only way to fix this annoying quirk is to switch to better email clients, such as Outlook, Spark, or Edison. These can push emails and show you a notification as soon as they reach your Gmail inbox. Alternatively, you can reduce the fetch period in the settings or manually sync the mailbox.
Check and Disable Both Power Saving Mode and Low Data Mode
To ensure your Gmail works without issues, download the official Gmail app from theย App Storeย and sign in with your account.
Next, check whether you have the power-saving mode turned on. iPhone stops syncing Gmail and other parts of the operating system to preserve energy after enabling power-saving mode. Go toย Settingsย >ย Batteryย >ย Low Power Mode.

Similarly, iPhone stops updating mail accounts when users turn on Data saving mode. Go toย Settingsย >ย Cellularย >ย Cellular Data Optionsย >ย Low Data Mode.

The next thing to do is check whether your Gmail account is properly set up in Settings. Go toย Settingsย >ย Mailย >ย Accountsย >ย Gmail.

Make sure you haveย Mailย enabled.

How iOS Background Restrictions Affect Gmail Sync
Note that modern iOS versions aggressively optimize battery usage and background network activity. Due to this, you may face email sync delay when:
- Low Power Mode is enabled;
- Low Data Mode is enabled;
- Background App Refresh is disabled;
- Focus modes restrict notifications;
- iPhone stays in sleep/standby mode for extended periods.
Keep in mind that Apple Mail relies heavily on iOS background fetch scheduling. This means that Gmail sync timing may vary depending on device activity, battery conditions, and network connectivity.
You can strongly notice this behavior on:
- older iPhone devices;
- low battery conditions;
- poor Wi-Fi/cellular networks;
- aggressive battery-saving configs.
Enable Two-Step Verification
Now, move on to credentials. Did you recently turn on two-factor authentication for your Gmail account? If yes, you need to sign in again to authenticate your iPhone and get Gmail syncing again.
If you didnโt enable it recently โ try to do this. If you recently enabled 2-Step Verification, you may need to re-authenticate the Mail app using the new Google OAuth flow. You can set this through Gmail account settings. When you will change the settings in Gmail account, you should configure Gmail account in the iPhone Mail application again.
Note that modern Gmail authentication on iPhone uses OAuth tokens instead of traditional password authentication. In some cases, expired/revoked Google authentication sessions may stop Gmail syncing on iPhone.
You should try to remove and re-add the Gmail account, it often refreshes authentication tokens and resolves sync issues.
Check Gmail account settings
Check if your Gmail account on the iPhone Mail app has correct settings. You should pay attention to the email address, username, and password you filled in.
Another important thing, is that when you add a Gmail account to your iPhone, the operating system asks for permission to read data in your Gmail. Your inbox will not work unless you grant that permission. In order to review app permissions for iPhone Mail, you should go to myaccount.google.com โ Security โ Third-party apps with account access and check if that iPhone Mail is listed.
Reset Network Settings
Important thing to try is do reset your network settings. Go to Settings > General > Transfer or Reset iPhone > Reset and tap on Reset Network Settings. This action will reset all network settings like passwords, cellular settings, Wi-Fi or VPN settings, etc.
After that close your Mail app and re-open again to see if the problem gone.
Clear Cache and Re-add Account
If you are still having trouble with Gmail on your iPhone, try:
- Removing the account (“Settings” > “Mail” > “Accounts”, then choose “Delete Account”).
- Then restarting your phone.
- After turning on your device, try adding your Account back (“Add Account” option under “Settings” > “Mail” > “Accounts.”).
This advice may sound dumb and stereotypical, but the truth is that restarting a device or removing and adding the account back often helps the user get rid of a bug that causes the problem.
Update iOS and Mail App
Finally, update your iPhone to the latest iOS version to fix Gmail not updating on iPhone. If still nothing helps, reset your device, and try again.
More tips to solve sync problems
- You should try to restart the Mail application on your device. Close the Mail app by double-clicking the Home button or swiping up from the bottom of your screen to access the application switcher. Here swipe up the Mail app to close it. After that, try to re-open the Mail application and check if the problem still appears.
- Check your mail inbox. iPhone stops syncing Gmail when your inbox is full. Hence the iPhone does not sync Gmail problem.
- Try to enable Background App Refresh setting (Settings > General > Background App Refresh). By enabling this feature, you are allowing applications to update with new data when even if those apps arenโt used much).
- Try to disable the Low Data mode (Settings > Cellular > Cellular Data Options). If you have enabled this feature before, it can block the application from using Internet to sync).
- Try switching on/off the Airplane mode. Turn it on wait for 5 seconds, then turn it off and check if problems with syncing are gone.
Check Focus Mode and Notification Settings
Sometimes Gmail syncing works correctly, but iPhone notification settings prevent users from seeing new mail alerts. You should check the following settings:
- Settings โ Notifications โ Mail/Gmail
- Settings โ Focus
- Scheduled Summary notifications
- Allow Notifications
- Background App Refresh
Note that focus modes and notification summaries may delay/suppress Gmail notifications (even in case messages are already synced successfully).
Enterprise and Managed Device Considerations
Keep in mind that in enterprise environments, Gmail sync problems may also be caused by:
- Microsoft Intune policies;
- Mobile Device Management (MDM) restrictions;
- VPN configs;
- conditional access policies;
- corporate security compliance rules;
- blocked background refresh settings.
In case your iPhone is managed by your organization, you should contact your IT admin to check that Gmail and mail syncing are allowed by device management policies.
Wrapping up
So, in most cases, Gmail syncing problems on iPhone are caused by:
- Apple Mail fetch limitations;
- iOS background activity restrictions;
- Gmail authentication/session issues;
- network connectivity problems;
- disabled IMAP access;
- battery optimization settings.
In case you want to get the best Gmail syncing experience on iPhone, you should prefer using the official Gmail app instead of the built-in Apple Mail app.
In enterprise environments, you should also verify device management policies, VPN configs, and security restrictions that may affect background sync.



I didn’t remove my gmail mail account because I don’t know how to re-install it, and if all of the deleted mail/folders will come back with it. But I did try all of the other suggestions.
Also, how do I know when my mailbox is full?
Gmail is still not retrieving new mail… past week(!)
This happened to my wife. Her mailbox was full so Gmail stopped pushing to her phone. We had to go on the desktop version of Gmail for it to tell us that was the reason.
