Have you ever noticed your mobile data running out too fast, even when you’re connected to Wi-Fi? A hidden setting on both iPhones and Android devices might be the reason. Features like Wi-Fi Assist (iPhone) and Adaptive Connectivity or Smart Network Switch (Android) automatically switch your phone to mobile data when your Wi-Fi signal is weak, potentially using up your data allowance without you realising it.
Let’s break down how these settings work, why they’re draining your data, and how to turn them off to avoid unnecessary usage.
What is Wi-Fi Assist?
On iPhones, Wi-Fi Assist is a feature that automatically switches to mobile data when your Wi-Fi connection is weak.
On Android, there are similar features known as Adaptive Connectivity, Switch to Mobile Data or Smart Network Switch, depending on the brand and model. These settings do the same thing: using mobile data in the background whenever your Wi-Fi connection is unstable.
How Wi-Fi Assist Works
If you’re on Wi-Fi and the signal weakens, your iPhone seamlessly switches to mobile data.
This happens in the background, meaning you might not even notice the change.
Any data-heavy tasks like watching YouTube, video calls or downloading files continue using mobile data instead of Wi-Fi.
As a result, you could exceed your data limit without realising it, leading to additional charges or throttled speeds.
Why You Should Turn It Off
While Wi-Fi Assist is meant to improve connectivity, it can be problematic especially for customers who have limited mobile data. Here’s why you should consider disabling it:
✅ Prevents Unintentional Data Drain – Since the switch happens automatically, many users don’t realise they are using mobile data instead of Wi-Fi.
✅ Saves Your Mobile Data Allowance – Avoid wasting your limited data on activities that should be covered by Wi-Fi.
✅ Avoids Additional Charges – If you exceed your mobile data allowance, you may need to purchase additional data or experience reduced speeds.
✅ Improves Control Over Your Internet Usage – You decide when to use mobile data instead of your phone switching on its own.
How to Turn Off Wi-Fi Assist (iPhone)
For iPhone users:
Open the Settings app.
Tap Mobile Data (or Cellular, depending on your region).
Scroll down to Wi-Fi Assist.
Toggle Wi-Fi Assist OFF.
That’s it! Your iPhone will only use Wi-Fi when connected, stopping unnecessary mobile data usage.
How to Turn Off Smart Network Switch (Android)
For Android users (Samsung, Google Pixel, and others):
Samsung Devices:
Go to Settings > Connections > Wi-Fi > Advanced Settings > Turn off "Switch to Mobile Data".
Google Pixel & Stock Android:
Go to Settings > Network & Internet > Adaptive Connectivity > Turn it OFF.
Other Android Devices:
Look for Wi-Fi+, Smart Network Switch or Adaptive Connectivity in your Wi-Fi settings and disable it.
Once turned off, your phone will no longer automatically use mobile data when Wi-Fi is weak.
