If your mobile data is turned on and you also turn on Wi-Fi on your mobile device, your device will automatically switch to Wi-Fi and stop using mobile data for internet connectivity. However, some apps on your device may continue to use mobile data even when Wi-Fi is turned on, depending on their settings.
A Wi-Fi connection lets you connect to the Internet without using any cellular data at all. While connected to Wi-Fi, you can also download videos, TV shows, or movies to your phone or SD card to watch anytime at your convenience, with no data required.

Connecting to WiFi automatically disables mobile data on most phones, so turning it off manually does not save your battery.
On LTE phones it will dramatically increase connect speeds.As others have said, when both WiFi and 3G are simultaneously connected, only WiFi will work. It will only used one of them, which one is the used first or selected.
Leave mobile data on and your battery will drain quicker than if it was off. There are a few reasons why this happens. First, your phone will be constantly searching for signal. If you're in an area with particularly poor signal, things only get worse, as your phone consumes more power while searching.
If your phone detects that the Wi-Fi network stutters, it will switch to the mobile network, so that your phone still consumes mobile data even if it is connected to the Wi-Fi network. To disable Wi-Fi+, go to Settings, search for and access Wi-Fi+, and disable it.
After turning off mobile data, you'll still be able to make and receive phone calls and get text messages. But you won't be able to access the internet until you reconnect to a Wi-Fi network. Most people have Wi-Fi at home, at work and at random food-and-beverage establishments such as Starbucks.
If activated, Wi-Fi Assist automatically switches to use cellular data when Wi-Fi connectivity is poor. Wi-Fi Assist is on by default. This might result in additional cellular data use, which could incur additional charges depending on your data plan. You can turn off Wi-Fi Assist in Settings.
Having WiFi and data on at the same time is pretty much OK, as it's usually not possible for your device to be using both at the same time unless it has 2 network cards. However, it does mean your device will switch to mobile data when you leave an area with WiFi access.
Using social media and messaging apps, like Facebook, Twitter, and WhatsApp. Streaming videos on platforms such as Netflix or YouTube. Streaming songs or playlists on music apps like Spotify, Apple Music, or YouTube Music. Playing games that need a signal and internet connection.
Go to Settings > Cellular, then turn Cellular Data on or off for any app (such as Maps) or service (such as Wi-Fi Assist) that can use cellular data. If a setting is off, iPhone uses only Wi-Fi for that service. Note: Wi-Fi Assist is on by default.

Every phone battery has a limit of numbers which you can charge it in. If the battery will drain fast due to active internet, this may harm the cell phone battery life.
The difference between Wi-Fi and Cellular Data
Wi-Fi connections are made by tapping into a network that already has an established connection. This means you need to be located near a router in order to get an internet connection. Cellular data, on the other hand, is accessed through the nearest cellular tower.
Tip: You can send texts over Wi-Fi even if you don't have cell service. Just use Messages as you normally would. If you're not connected to Wi-Fi, make sure cellular data is turned on: On your Android device, open the Settings app.
Important information about choosing the No Data plan:
Basic Phone - Group texts and picture/video messaging will not be available. Android Smartphone - Group texts and picture/video messaging will not be available.
Offline messaging is a new trend in secure communication. The off-grid messenger apps, also known as mesh messengers, don't need access to public infrastructure like cell phone towers or internet to send messages from one phone to another. Instead, they rely on Bluetooth or direct Wi-Fi connection.
Should mobile data be on or off? Whether you choose to keep mobile data on or off depends on your phone contract and data allowances. If you leave your mobile data on, some applications running in the background may continue to consume your data allowance even if you're not actively using them.
No, you will not be charged if you turn off cellular data but do not turn on airplane mode for an hour abroad. However, it is always a good idea to make sure that your phone is in airplane mode when traveling internationally as this will prevent any unexpected roaming charges from occurring.
A lot of apps will quietly run in the background, which can drain your battery and burn lots of mobile data. Consider deleting apps that do this regularly, or (on Android) use some advanced options in Developer Mode to limit background processes.
Mobile data is the internet connectivity provided by your mobile network provider. While your phone will automatically switch to Wi-Fi if a network is available, you can manually control your mobile data use by enabling and disabling it.
App syncing, updates, notifications, and autoplay
These functions, while convenient, can use data in the background. For example, videos often play automatically as you scroll through your newsfeed on social media apps. You may want to disable cellular data for video autoplay within each app's settings on your device.
If your data is turned on, then you may be charged for background data. Background data is data that your apps are constantly using, it could be when your phone is in your pocket or even when you are asleep! Some apps - such as MyDigicel - do not incur a charge for this background data. However, most apps are not free.
Data usage is how much data your phone uploads or downloads using mobile data. To make sure that you're not using too much data on your data plan, you can check and change your data usage.
