Thirteen quick switches will stop Google Photos from quietly filling your shared 15 GB. ZDNET published a how-to that walks through the 13 toggles its author flips on every new Android and iPhone to avoid unwanted uploads, shrink storage use and shut off features they find intrusive. They fall into three practical groups: which account and folders actually upload, the upload quality that determines how fast your quota fills, and the app's newer AI and Memories settings that can surface things you do not want to see. The guide also reminds readers backups run per device, so turning off backup on one phone does not stop a second device signed into the same account from uploading. Run this short checklist once on any new device and you stop months of accidental backups and surprise storage warnings.

In the Photos app the profile picture is the first stop, and the setup flow makes account selection feel like a casual last step.

Start with account and backup controls

Open Google Photos, tap the profile picture, then Photos settings and Backup to confirm which Google account is listed and whether Backup is enabled. That simple sequence is the backbone of the ZDNET walkthrough because it determines which account actually receives your photos. The author recommends keeping backup enabled but narrowing what the app can read so screenshots, downloads and other non-camera folders don't flood the cloud.

On iPhone the piece tells readers to set Photos permission to Limited Access in iOS Settings so you pick specific photos and folders instead of granting blanket access. On Android the equivalent paths are Apps > Photos > Permissions or the app’s Backup options where you can restrict folder selection. The how-to stresses a practical gotcha: backups run per device. Turning backup off on one phone doesn't stop a tablet or a second phone that's signed into the same Google account from uploading.

Storage settings are the second priority because they directly affect how much of your Google Account quota photos consume. Google renamed its former High quality tier to Storage Saver in 2021. Storage Saver compresses images to a maximum of 16 megapixels and videos to 1080p, and the ZDNET guide recommends switching future uploads to Storage Saver if you want to stretch the shared 15 GB across Photos, Drive and Gmail.

Mastheads

The change to Upload size or Backup quality in Photos settings takes effect immediately for new uploads. One how-to guide cited in the source material says Storage Saver can reduce per-photo file sizes enough that users can store roughly two to three times as many images in the same quota versus original quality, which makes it a quick, high-impact fix when recurring storage warnings arrive.

The third set of switches addresses Google Photos’ newer AI features, Memories and privacy controls. The author advises reviewing Gemini-powered features and turning off the Ask Photos AI search if you prefer the classic keyword search experience; you find that toggle under Photos settings > Preferences > Gemini features, according to a separate how-to.

This walkthrough also explains how to hide specific faces from Memories so former partners or unwanted people don't appear in the curated row at the top of the app.

Practical toggles worth flipping while you are inside settings: disable automatic backup of screenshots and downloaded images, and double-check Android system backups so other data types you don't want in Google Cloud aren't synced. One of the background sources notes that Android’s broader backup scope can include call history, SMS and device settings, so the author recommends auditing Android-level backup controls at Settings > Google > Manage backup if you want to limit cloud-synced system data.

Taken together these moves are short to perform and high-leverage in effect. They stop a cascade of small, default behaviors that otherwise hand Google Photos your entire camera roll, every screenshot and downloaded image, and then bill that behavior against the shared 15 GB quota without an obvious signal.

The walkthrough in ZDNET walks readers through each toggle for both iOS and Android, step by step, because the menu names and permission dialogs differ between platforms. The article stresses the practical ergonomics: a few quick taps in Settings prevent months of accidental uploads to the wrong account, surprise storage prompts and the awkwardness of Memories surfacing sensitive or unwanted images.

Make these three checks the first thing you do after installing Google Photos: confirm the account and per-device backup, set Upload size to Storage Saver if you want smaller files, and vet Gemini, Ask Photos and Memories options so the app surfaces only what you consider useful. Do that once and the app will behave the way you expect, rather than filling the wrong account or your shared quota by default.
