The endlessly rotating Gmail synchronization indicator on an Android phone blocks the receipt of new emails and provokes rapid battery drain, indicating a failure in data exchange with Google servers.
Most often, the problem lies not in the breakdown of the phone itself, but in software conflict or network settings. Sometimes simply switching the network mode is enough to get the process going, but in other cases deeper intervention in the system is required. In this article, we will analyze all possible causes, from simple Internet failures to errors in the service Google Play Services, and will offer a step-by-step algorithm for restoring normal operation.
Primary diagnosis of a network connection
The most obvious, but often ignored, reason for synchronization freezes is an unstable Internet channel. Data exchange protocols Gmail are sensitive to connection breaks. If you're in an area with poor cellular reception or on a congested Wi-Fi network, data packets may be lost, causing the app to try to send the request over and over again.
Try switching from Wi-Fi to mobile data or vice versa. Sometimes the problem is solved by simply turning airplane mode on and off. This action causes the modem to reconnect to the nearest tower or router, updating the IP address and data routes.
⚠️ Warning: If you are using a corporate Wi-Fi network, administrators may have blocked certain ports required for Google services to function. In this case, synchronization will only work via a mobile network or home Internet.
It is also worth checking whether you have traffic saving mode enabled. This feature can limit background data transfer for applications, which causes the synchronization process to freeze. Go to Android may limit background data transfer for applications, causing the sync process to freeze. Go to Settings → Network and Internet → Traffic saving and make sure that an exception is set for mail or the mode is completely disabled.
Try opening any heavy website in the browser. If pages load slowly or do not open at all, the problem is definitely in the Internet, and not in the mail settings.
Checking your account synchronization settings
If everything is fine with the Internet, the next step should be to check the internal settings of your profile. In the system Android each account has its own synchronization flags, which could accidentally get lost after updating the system or the application itself.
You need to go to the account management menu and force the update to run. Often the system simply “forgets” to send a command to start the process, and manually pressing a button solves the problem instantly. Make sure the checkbox next to Gmail synchronization is active.

Pay attention to the status of other services in the same menu. If synchronization of contacts or calendar is also frozen, the problem is systemic and affects the entire account, not just the email client. In this case, simply refreshing the page will not help, you will need to delete and re-adding the account.
Clearing the cache and data of the Gmail application
Accumulated temporary files can become a serious obstacle to the normal operation of the app. The application cache Gmail is designed to speed up loading, but if it becomes damaged, it begins to conflict with new data coming from the server. This is one of the most common reasons why a process cannot complete.
It is important to distinguish between the concepts of “clear cache” and “clear data”. The first operation is safe and only deletes temporary files. The second operation resets all application settings to factory settings, but does not delete your emails, since they are stored on the server.
Settings → Applications → Gmail → Storage → Clear cacheIf clearing the cache did not help, try a more radical method - clearing data. After this, you will have to reconfigure the signature and notifications in the application, but this often “cures” deep software errors. It is also recommended to check for updates for the application itself in the store Google Play, since developers regularly release patches that fix such bugs.

The role of Google Play services in the synchronization process
Many users do not know that the mail application does not work isolated. The system component Google Play Servicesis responsible for authorization, push notifications and background data exchange. If this service does not work correctly or its version is outdated, mail synchronization will constantly hang in the “Pending” status.
Check the version of Google Play services in your phone settings. Sometimes after a major update Android system services require reinitialization. In rare cases, uninstalling updates for this component and then automatically downloading the current version helps.
| System component | Function | Impact on Gmail |
|---|---|---|
| Google Play Services | Background authorization | Critical: without it login impossible |
| Google Services Framework | Data synchronization | High: responsible for transmitting packets |
| Android System WebView | Displaying content | Medium: affects opening emails |
| Download Manager | Downloading attachments | Low: for files only |
If you have recently installed third-party launchers or system tweakers, they may have changed permissions for system services. Return permission settings for Google Play Services to default values to eliminate access rights conflicts.
⚠️ Attention: Do not uninstall the Google Play Services application completely if you do not have superuser rights (Root). This can lead to the inoperability of most applications on the phone, including banking clients and navigators.
Deleting and re-adding an account
When simple methods do not help, you have to resort to completely re-creating the connection between the phone and the server. Removing an account from a device breaks the authorization token, which may have been compromised or expired. This action is safe for your data as all mail is stored in the cloud.
Before performing this procedure, make sure you remember your account password. After deleting, you will need to enter it again. If you have two-factor authentication enabled, prepare your phone to receive a verification code.
What happens when you delete an account?
When you delete an account from your device, all local copies of contacts, notes and calendars associated with this particular profile on this phone are erased. Gmail emails are not deleted, since they are stored on the server and will be downloaded again after logging in.
The deletion process is as follows: go to Settings → Accounts, select the desired email address and click the Delete accountbutton. After this, restart your smartphone. This is an important step that clears the RAM of residual processes associated with the previous session.
After turning on the phone, add the account again through the settings menu. The system will re-request all necessary permissions and install fresh security tokens. Usually, after this procedure, synchronization begins to work stably and without freezes.
Complete deletion and re-entry into the account is the most effective way to reset authorization errors that are not visible to the user, but block the operation of services.
The influence of energy saving and third-party antiviruses
Modern shells Android from manufacturers like Xiaomi, Samsung or Huawei have very aggressive energy saving algorithms. They can forcefully “freeze” background processes of the application Gmail, considering them a waste of power, which leads to a breakdown in synchronization.
You need to find the battery settings for a specific application and prevent the system from limiting its operation. This option is usually called “No restrictions”, “Do not restrict” or “Allow background activity”. Without this permission, the phone will constantly kill the synchronization process, and it will restart indefinitely.
Also check your installed antiviruses and memory cleaners. Some have an "App Sleep" or "Background Activity Blocker" feature that can accidentally block Google's sync service. Try temporarily disabling the third-party antivirus and check if the problem has gone away.

Frequently asked questions (FAQ)
Why does synchronization only work when connected to a charger?
This is standard behavior when hard power saving mode is enabled. The system prohibits background data synchronization to save battery power. Disable super-saving mode in your battery settings to allow it to run in the background.
Deleting your account will cause you to lose all your emails?
No, your emails are stored on Google servers. When you delete your account, only local settings and cache are deleted from your phone. After re-logging in, all emails will be downloaded again. However, local contacts that are not saved in the cloud may be lost.
How can you find out what error is preventing synchronization?
Go to Settings → Accounts → Google. If there is an error, it will say in red text, such as "Action Required" or "Authentication Error". By clicking on this message, you will be taken to the browser to solve the problem (for example, change your password).
Can a full phone memory stop synchronization?
Yes, if the device has critically low free space (less than 100 MB), the system may block writing new data, including the mail cache. Free up space by deleting unnecessary files or applications, and try syncing again.
Does changing your Google password affect synchronization?
Yes, if you change the password on another device, the old access token on the phone will become invalid. Sync will freeze trying to connect with old data. You need to either update the password in the account settings on your phone, or delete and add the account again.
