By the end of August 2026, all Android device backups will count toward your Google account's storage quota. If your account is full, your phone will stop backing up until you free up space. While the additional data per backup is only about 30-60 MB, many users have unknowingly accumulated duplicate files that consume gigabytes of precious storage.
The most common mistake involves double backups of photos and videos. Messaging apps like WhatsApp download copies of every image and video you view. If Google Photos is set to back up all device folders, and WhatsApp also backs up chats with media to the cloud, you are storing each file twice without realizing it.
How to find and fix duplicate backups
Android backup settings are located in Settings under Backup. Data is divided into Photos and videos, Documents, and Other device data. Documents take negligible space, but Other device data includes SMS, call history, and app data. Disabling backup for non-essential apps saved me about 200 MB.

The real savings come from adjusting Google Photos backup folders. By deselecting WhatsApp folders from Google Photos backups, I saved approximately 8 to 12 GB per year. A quick audit of all app folders that store images can reveal similar duplicates. I recommend checking your Google Photos device folder backup settings monthly.
Additional tips to free up Google storage
Google also offers suggestions to clear unnecessary files like blurry photos or screenshots. Following these tips can further reduce storage usage. Even if you have a temporary storage boost from a Pixel phone, these settings will help you avoid paying for extra space after the trial ends.
