Handle Bandwidth Usage: Complete Guide To iOS 13

Internet connections without some kind of bandwidth cap or overage fee are difficult to find. Fortunately, there are tricks you can employ to manage your

bandwidth usage in iOS. All these tricks can help you reduce your use of cellular data on your iPhone or iPad, but some can also help you stay under a general broadband internet

cap, too.

Turn On Low Data Mode

iOS 13 and iPadOS 13 introduces a new feature called Low Data Mode, which promises to reduce your overall data usage. The only problem is, Apple hasn’t

been terribly open about how this exactly works, so while I recommend enabling it if you’re trying to save data, don’t expect it to be a panacea. However,

it will do things like warn you before you download large apps. You can enable it for Wi-Fi or cellular connections, and you can choose to enable it for

individual networks.

Enable Low Data Mode for Wi-Fi Networks:

  1. Go to Settings > Wi-Fi.
  2. Tap the info button for the network you want to limit.
  3. Turn on Low Data Mode.

Enable Low Data Mode for Cellular Data:

  1. Go to Settings > Cellular > Cellular Data Options.
  2. Turn on Low Data Mode.

Monitor and Disable Cellular Data Usage

In Settings > Cellular, under Cellular Data, iOS lists every app that has used cellular data, along with a tally of how much data it has used since you

last tapped Reset Statistics at the bottom of the screen.

Turn off the switch for any app that you don’t want using cellular data. Beware that if you disable cellular data for an app, it won’t be able to use cellular

data for any purpose, possibly rendering it useless when off Wi-Fi.

Tip: Wi-Fi Assist makes your device automatically use cellular data when your Wi-Fi connection is poor, but that can lead to surprise data overages! Disable

it at the bottom of Settings > Cellular.

Stop Automatic Downloads

When you buy an app, ebook, or music from Apple, it downloads to your device automatically. These purchases can also automatically download to all your

other devices, so long as they are signed in with the same Apple ID. For example, if you bought an ebook from Apple’s Books Store on your iPad, it may

have downloaded automatically to your iPhone. Although this feature is convenient, it can eat data quickly.

To disable automatic downloads—and turn off automatic app updates—toggle the appropriate switch in Settings > iTunes & App Store. If you don’t want to

disable automatic downloads entirely, you can instead disable Automatic Downloads under Cellular Data on this screen. You can also tap App Downloads to

always be asked if you’d like to automatically download items over cellular, or just items over 200 MB.

Tip: If you disable automatic app updates, you should occasionally update your apps in the App Store. See

Update Apps


Restrict Background App Refresh

Background App Refresh keeps certain apps updated even when they’re in the background. While this feature keeps app content fresh and saves you from waiting

for data to load when you launch an app, it can also eat data without you realizing it.

You can disable Background App Refresh entirely, or on a per-app basis, in Settings > General > Background App Refresh. You can also tap Background App

Refresh at this screen and choose Wi-Fi to disable Background App Refresh entirely or only when on cellular data.

Limit iCloud Data Usage

Some iCloud services (shown in Settings > Your Name > iCloud) can use a lot of data, including Photos, Safari, News, and Backup (backups happen over Wi-Fi

only). Consider disabling these services if you don’t use them.

Turn Down the Music

The Music app can consume an overwhelming amount of data, especially if you use Apple Music, iCloud Music Library, or iTunes Match, or listen to online


Tap Settings > Music > Cellular Data to find options for controlling Music’s cellular bandwidth usage:

  • Turning off Cellular Data does just that. You’ll only be able to listen to downloaded music while on cellular connections.
  • Enabling Cellular Data in Music lets you control whether Music can use cellular data for streaming or downloads separately.
  • If you choose to enable Streaming, you can turn off High Quality Streaming to lessen the impact on your data cap.

You can also enable Automatic Downloads in Settings > Music to automatically download songs in your library for offline playback. This cuts down on data

usage, but drastically decreases the free storage space on your device. The Optimize Storage setting in Settings > Music automatically removes downloaded

music when your device is low on space.
