Common Data Hogs – Where To Start Hunting When Your Data Usage Spikes

Mobile internet comes with limits and one of those limits is data usage - even on an "unlimited" data plan. No matter how careful you are when traveling in your boat, RV or other nomadic conveyance, you will inevitably (but accidentally) use way more data than you realized or thought possible.

With blazing fast LTE speeds, it's entirely possible to blow through a whole month's cellular data allowance before you even realize it.

Your electronic devices may wake while you slumber to download operating system, app, game or software updates, leaving you with no data to enjoy with your morning coffee.

It is tempting to immediately blame your internet provider and to disclaim all personal responsibility. We hear it all the time - “there’s no way I could have used that much data!”

Heck, we’ve said it ourselves when notified of high usage. But in reality, screwed up accounting behind the scenes is only occasionally to blame.

Very often some forensic digging finds the real guilty party - and chances are your computers, phones, tablets and other electronic devices are secretly eating your data.  In this guide, we show you how to find and quash those data hogs.

Overview

Hidden data hogs are a very real threat to your mobile internet data and they are difficult to stop because most internet-enabled devices are designed to be used with a home "always on" and truly unlimited connection.

We have also seen bugs, like OS updates and iTunes ignoring  “auto-download” settings, Google’s Photos silently opting-in to “backup all photos to the cloud” after an upgrade, and even an Xbox One turn itself on in the middle of the night to download a huge 4GB update with no disclosure or warning given.

If you find yourself starting to get overage charges from your carrier, or approaching your bandwidth cap much quicker than usual, then this guide lists some of the common bandwidth hogs that might be affecting you.

You can also use these tips to double check and perhaps preemptively avoid a surprise overage charge or hotspot throttle.

 


Video Streaming

It's the single biggest bandwidth hog most people regularly encounter.

Get the Book

Make sure you have your video streaming services set to use the lowest amount of bandwidth you can tolerate - this can save many GBs. Increasingly, cellular companies are implementing bandwidth caps on streaming, though you can often opt-out.

Remember, an HD video stream can use 2-7 GB per hour.  If you don't absolutely need HD, this is an easy area to cut back on data usage.

Auto Updates

Make sure you have auto-downloads of system and software updates turned OFF. You'll find the settings scattered through various software preferences, but it's well worth the time to investigate. Save updates for when you have unlimited internet!

A big OS update might be a couple gigabytes in size. Wait and download these later if you can. A smartphone OS update might auto-trigger the first time you're on WiFi (regardless if your WiFi is a capped cellular plan), and restore all your photos, apps & data from the cloud.

Game consoles, Blu-ray players, and even some smart TVs can use up to a ton of data silently, in the middle of the night, downloading updates. Do not leave these devices plugged into mobile internet unless you are keeping a close eye on them.

Even if you do have auto updates turned off, or set only to use while you are on WiFi - these settings sometimes get ignored. And of course, if you're broadcasting your cellular data over your own WiFi network - your other devices might not be able to tell the difference.

Here are some historic examples of forced software updates that caught mobile users off guard:

Even if you think you have the settings tuned just right, things can easily get messed up – sometimes causing repeated attempts at partial syncing and upload. Or a software update overwrites your previous settings, forcing automatic updates again.

 


Auto Playback

Be very careful when you load a webpage with a video on it. If it autoplays, it’s very likely caching faster than you can watch it. Meaning if you click away partway through the video, you’ve already spent the data – regardless if you actually saw the whole thing. Even if you click “Pause” or “Stop,” it often still caches in the background.

And of course, turn off auto video playback in as many places as you can.

Cloud Syncing - Backups, Photos & Subscriptions

Cloud-based services (where the application and/or data are dependent on an internet server) are great... As long as the cloud is working and you have the data to support the updates.

Whenever you use a cloud service - ask yourself what you would do if it went down for an hour or a day? Being on mobile internet means you might not be able to access the cloud when you need to.  It also means that you could, unknowingly, use a lot of data from syncing between you and the cloud platform.

When it comes to pictures of video, cloud syncing can quickly consume many gigabytes of data, all automatically without input from you!

Pause auto-syncing to your cloud-based services is one way to control this hidden data use.

  • Cloud backup services: Cloud services like DropBox, auto sync files which continuously update by default. Instead - consciously decide when you want to sync to backup services. Even still, it's possible for a large file to get 'stuck' and attempt to resync multiple times which chews up your bandwidth.  Also, when working with large files, sometimes it's best to bring the file down locally and periodically back it up to the cloud yourself. We've hit our caps in the past by making this mistake, as a 250MB graphics file being backed up with every change will burn through data very fast.
  • Manage Subscriptions: If you are subscribed to podcasts, TV series, or any other periodical content through programs like iTunes, be extra vigilant that you are not auto-downloading new episodes in the background. Save the downloading for when you have access to uncapped bandwidth, or consciously choose when you use the data.
    • Tip: If you have multiple computers and devices, make sure that they aren’t duplicating downloads. If you are subscribed to a podcast that you want to download new episodes of, make sure that you are doing so on only one of your devices. No sense having three copies of something!
  • Manage your photo syncing: In programs like Google Photos, iPhotos, or others, syncing all of your photos over capped bandwidth will chew through data like crazy. As photos get larger and larger, these consume more and more data. We've seen photo syncing apps chew through 10-20GB a DAY in the past.

 


Apps & WiFi

WiFi Assist: Some phones have a feature called 'WiFi Assist' that uses your cellular data if they encounter poor WiFi. This can unintentionally chew through your data. We recommend turning this feature OFF.

A lot of apps, unless they are specifically designed for mobile usage, are built with the assumption that data is unlimited. Even when they appear to be idle, some apps are actually burning through data in the background - downloading updates, content that you may never even view, or even updating advertising for quicker display later. Be careful of what you leave running in the background!

If you have a WiFi hotspot that is powered by cellular data, you need to be extra careful about lurking data hogs on your phones and tablets. A lot of mobile apps are conservative if they know they are on cellular data, but they have no way to know that your WiFi network is actually cellular powered. Many apps save their uploading and downloading for the first hint of WiFi, and there might be a backlog waiting the next time you connect to a WiFi network.

 


Tracking Your Data Usage

To determine how much data you use, and avoid surprise overages or accidental account suspensions, you need to keep on top of your data usage. Most internet providers give their customers a way to check usage directly with them – either via a customer login account online, an app, or sending a text message on smartphones. Check with your carrier for instructions on how to do this for each of your devices.

Set it up, and get into the routine of checking each of your internet sources throughout the month to make sure you’re staying within your quotas.

Some devices also have built-in usage tracking right on the device. Many modern mobile hotspots make this really easy and display your usage and limits right on the control panel screen, or even via a companion smartphone app. The device retrieves the carrier’s report of how much data has been used so far in the billing period for display.

Most phones also allow you to see data usage by app on your phone (it is generally found in the Settings area of your phone), but you might need to reset this tracking every billing period manually to keep on top of it.

If you don’t have an easy way to tap into your carriers usage metering in real time, you’ll need to track it on your own.

Tracking your own independent usage can also help you figure out if you have a rogue program sucking up bandwidth – such as a sync to the cloud or a large update downloading. And if there’s an unexplained spike in usage on your carrier’s reporting, you can go back to your logs and see if it’s accurate or perhaps an erroneous report that you need to refute with the carrier.

Or if you suspect your carrier is misreporting your usage, the only way you can prove it is by having your own independent accurate data logs.

  • There are multiple ways to independently track your usage - ranging from apps, software programs and built-in features on routers. We have an entire section covering many options, including links to tools, in our guide on Assessing Your Mobile Internet Needs.

 


Other Bandwidth Saving Tips

If you ever accidentally blow through your data cap on your primary cellular account, it is extremely useful to have a secondary way online to help you limp through to the end of the month when your caps reset.

And of course, nothing beats having a truly unlimited data plan, so you don't have to worry about data caps, but most "unlimited" plans need scare quotes because there are usually restrictions on data use and, especially, using hotspot data.  Our guide to Unlimited Data will have all the available options as well as an explanation of the caveats.

Most carriers have also recently switched their tiered data plans so that when you reach your cap, there are no overages - your speeds just slow down. It may be worth switching to one of these plans if you're constantly hitting your data cap and don't want to risk overage charges.
