You’ll be surprised just how much space images and videos from WhatsApp can take up on your smartphone.
This is especially true when it comes to groups. To save data and space, switch off media auto-downloads on the app. With this disabled, you can choose to manually download the media by tapping on it instead. To switch off auto-downloads, go to your Settings and then the ‘Data and storage usage’ tab. You can then tweak your settings under the ‘Media auto-download’ menu, and choose which media types you’ll allow to auto-download on your device and when.
