If you are concerned about Cellular Data Usage by WhatsApp, you can find below the steps to Reduce Mobile Data Used by WhatsApp on iPhone.
Reduce WhatsApp Mobile Data Usage on iPhone
The default WhatsApp settings on iPhone can end up consuming an excessive amount of your expensive Cellular Data.
For example, the cost of using WhatsApp on Cellular Data can be significant, if your device is set to automatically download WhatsApp Photos and Videos using Cellular Network.
Luckily, it is easy to Monitor Cellular Data used by WhatsApp on iPhone and take preventive measures to reduce or even totally prevent WhatsApp from using Cellular Data on iPhone.
1. Enable “Use Less Data for Calls” Option
An easy way to reduce Cellular Data Usage on iPhone is to enable “Use Less Data for Calls” option, as available within WhatsApp.
1. Open WhatsApp and tap on Settings option located in bottom menu.
2. On the Settings screen, select Storage & Data option.
3. On ‘Data and Storage’ screen, move the toggle next to Use Less Data to ON Position.
After this, you should find your iPhone using less data for WhatsApp Calls, compared to its earlier data usage.
Note: According to WhatsApp, you won’t find much difference in call quality, even if “Use Less Data for Calls” option is enabled on iPhone.
2. Disable Mobile Data Usage for Photos and Videos
