You can find and enable Low Data Mode on your iPhone in the Settings app, with slightly different steps depending on whether you want to use it for cellular data or Wi-Fi: For Cellular Data:
- Open Settings and tap Mobile Data (or Cellular).
- Tap Mobile Data Options (or Cellular Data Options).
- For 5G, tap Data Mode , then toggle on Low Data Mode.
- For LTE/4G, simply toggle on Low Data Mode.
- If you have Dual SIM, tap the number you want to configure, then turn on Low Data Mode for that line.
For Wi-Fi:
- Open Settings and tap Wi-Fi.
- Tap the info button (ⓘ) next to the Wi-Fi network you are connected to.
- Toggle on Low Data Mode.
This mode reduces background network activity, pauses automatic downloads and backups, lowers streaming quality, and limits app refreshes to help save data usage
