Do you use a limited mobile data plan (3G / 4G), and you want to save data by extending your usage time? The Low Data Mode feature on the iPhone will help you.
Low data mode will turn off all background communication. It turns off the Background App Refresh feature of the app and requires the app to suspend all sync tasks until you connect to the unlimited network.
Besides, it also turns off all background sync tasks. Therefore, when you enable this mode, the Photos app will not back up your photos.
You won’t notice the difference when using your iPhone for basic daily tasks, but all background processes you don’t control usually will be halted. If necessary, you can enable sync tasks for each application manually.
