If they are so many then it is likely that they are the causes of phone using so much data on your cell phone.

What you have to do

After going through your monthly data usage on your cell phone and finding out the apps that are taking most of your cell phone data plan, you have to restrict background apps from these apps.

First, I will recommend you to disable all auto update like the software update and apps updates using your cell phone data instead of Wi-Fi.

For background apps, the likes of Facebook app, Facebook messenger app, whatsapp, Twitter, Skype, imessage, Instagram, Pinterest, App store and Google play store, Google play services, online shopping apps, etc all uses a cellphone data plan in the background especially the likes of Google play store and Apple App store.

Disadvantage of restricting data on background apps

The will no longer be able to send notifications on your cell phone, you won’t receive Facebook notifications, whatsapp messages, imessages, Twitter notifications, Instagram notifications, etc, until you open the apps. 

Immediately you opened the apps on your cell phone, you will receive the notifications as long as you have an active internet connection.

2. LOOK FOR WHATSAPP: You have to scroll down to whatsapp or search for it using the search button, and upon seeing it tap and open it.

4. DISABLE ALLOW BACKGROUND DATA USAGE: Immediately you opened mobile data, on the next screen you will see where it states allow background data usage which is usually enabled by default. You can go ahead and disable it on your cell phone.

Whatsapp data usage

With this you have restricted whatsapp from using your cell phone data plan when you are not using it. Whatsapp will only use your data plan when you are using it.

Remember, this will prevent you from receiving WhatsApp messages and calls until you open your whatsapp you will receive messages and calls.

This is applied to any other background data apps like Facebook app, Twitter, app store, etc.

After you must have restricted data from these apps when you are using them, you won’t experience a surprised high data usage on your cell phone.

Let me show you how much background data my whatsapp have used so far this December.

That is 30.17mb from 1st December to 22nd December. If you are the type that has lots of whatsapp groups, it will reach up to 100mb because of the number of messages sent by the group members.

Your network provider may have increased the data rate

This is another reason for this problem of why is my phone using so much data all of a sudden, your network carrier has increased the data rates.

For example, if previously loading a full web page takes 2mb, they increased it to 4mb. If the web page has lot’s of high quality pictures, pop-ups, and video, it may take 8mb for the page to load fully.

You can inquire from your network carrier customer service representative on their data consumption rates though most time they wouldn’t tell you.

What causes high data usage on my iPhone?

Most times what causes high data usage on iphone are auto updates which is enabled on both WiFi and cellular data. But same time high data usage on iphone goes down to the iPhone user’s internet activity. 

While asking why is my phone using so much data all of a sudden, previously you may not be the type that stream YouTube videos or watch Netflix movies, then since the turn of the month you started to stream online.

Afterwards you begin to complain of your data plan draining so much. I tell you don’t have to complain because Netflix alone will consume 2GB of your cell phone data within an hour, while Youtube will consume like 400mb depending on the video quality.

How do I stop my phone from using so much data?

To stop your cell phone from using so much data, you must restrict background app data usage, and reduce the quality of videos you stream online.

Mostly high data usage on a cell phone goes to down to the phone user’s internet activity. You will see a person consuming just 2GB per month on cellular data, while another person consumes 100GB on cellular data.

As long as you don’t have an unlimited data plan, limit your internet usage unless you don’t care about the amount you spent on cellular data. But I recommend you to go for a Wi-Fi if applicable.

This is all I have to explain on why is my phone using so much data all of a sudden. First you need to identify all that is using your cell phone data plan and restrict them from using your data in background until you open them.
