How to Speed Up Your iCloud Backups and Safeguard Your iPhone Data Faster

As an iPhone user, you know the importance of backing up your device regularly. It‘s the best defense against losing your precious photos, messages, notes, and other data if your phone is lost, stolen, or damaged. But if you‘ve ever been frustrated by how long your iCloud backups take, you‘re not alone.

According to a recent study by Acronis, the average iPhone user has 148 apps installed and snaps over 3,000 photos per year. All that data adds up—Apple reports the average iCloud backup size has grown to a whopping 8.3 GB as of 2022. Even on a speedy broadband connection, uploading that much data to the cloud can take hours.

But don‘t give up on iCloud backups just yet. As a Mac and iOS software expert with over a decade of experience, I‘m here to share my top two strategies for making your iCloud backups faster: minimizing your backup size and maximizing your upload speed.

The Two Factors That Determine iCloud Backup Speed

Before we jump into optimization, it‘s important to understand the two key variables that govern iCloud backup times:

1. Backup size (the total amount of data being backed up)
2. Upload speed (how fast that data can be sent to Apple‘s servers)

Backup size is measured in megabytes (MB) or gigabytes (GB). One photo might be 5 MB, while an hour-long video could be 500 MB or more. The sum of all your apps‘ data, media, messages, and iOS settings is your total backup size.

Upload speed measures how much data your internet connection can send per second, typically expressed in megabits per second (Mbps). The higher your Mbps, the faster your backup will complete.

Here‘s the golden rule: to cut your backup time in half, you must either halve your backup size or double your upload speed. Even better, do both! Let‘s explore how.

Strategy 1: Minimize Your iCloud Backup Size

Bloated backups waste time and storage space. Fortunately, you can put your iCloud backups on a healthy diet by pruning expendable data. Follow these step-by-step instructions:

Step 1: Delete unused apps and data

Did you know a single unplayed mobile game could add over 1 GB to your backup size? Removing apps you no longer use is the easiest way to shrink your iCloud backup. Here‘s how:

1. Open the Settings app, tap General, then iPhone Storage
2. Browse the list of apps, sorted from most to least data stored
3. Tap any apps you want to remove, then tap Delete App
4. Repeat until you‘ve cleared out any unnecessary apps

Apps not updated for iOS 15 will display an alert in this list—consider these prime candidates for deletion.

For important apps you want to keep, check how much data they‘re holding by tapping them in this list. Clear any cached files, saved media, or old message attachments you no longer need to reduce their iCloud backup footprint.

Step 2: Disable app backups you don‘t need

Certain types of app data don‘t need to be preserved in iCloud backups. For example, podcast downloads, digital magazines, and e-books can easily be re-downloaded later if needed.

To choose which apps back up to iCloud:

1. Tap your name at the top of the Settings app, then tap iCloud
2. Tap Manage Storage, then Backups
3. Select your device
4. Under Choose Data to Back Up, toggle off any unnecessary apps

Be judicious about disabling backups for productivity and creativity apps, as they may store harder-to-recover data. When in doubt, leave it on.

Step 3: Enable and use iCloud Photos

For most iPhone users, photos and videos comprise the lion‘s share of storage consumption. Enabling iCloud Photos can dramatically reduce your iCloud backup size. Here‘s why:

With iCloud Photos enabled, every picture and video you take is automatically uploaded to iCloud, in full resolution. This happens continuously in the background, so your photos are always safe.

During a full iCloud backup, your device checks to see if all your photos are already in iCloud. If so, it skips backing them up again, saving tons of time and bandwidth. Instead, it just backs up the much smaller photo metadata and thumbnails.

If you take a lot of photos and video, enabling iCloud Photos could reduce your backup size by gigabytes and speed up your backups significantly. Go to Settings > Photos to turn it on.

Step 4: Delete old messages and attachments

Years-old iMessage conversations, especially those loaded with GIFs, videos, and other attachments, could be inflating your iCloud backups unnecessarily. To review and delete them:

1. Open Settings, tap General, then iPhone Storage
2. Scroll down to Review Large Attachments
3. Tap Edit, select any attachments to delete, then tap the trash icon
4. Go back to the iPhone Storage screen and tap Show All under Messages
5. Tap Edit, select whole conversations to remove, then tap Delete

Attachment sizes are listed to help you find the biggest space hogs. Don‘t delete any memorable photos or videos you want to keep—just expendable items like memes and clips.

With these four steps, most iPhone users can reduce their iCloud backup size by 50% or more. Here‘s a table summarizing the estimated space savings:

Optimization Technique	Estimated Backup Size Reduction
Delete unused apps and data	10-30%
Disable unnecessary app backups	5-10%
Enable iCloud Photos	30-60%
Delete old messages and attachments	5-20%

Strategy 2: Maximize Your Internet Upload Speed

With your iCloud backup whittled down to fighting weight, it‘s time to optimize your internet connection to send that data to Apple‘s servers as fast as possible. Try these tips:

Connect to fast, uncongested Wi-Fi

According to Ookla, the median fixed broadband upload speed in the United States was 19.54 Mbps in Q1 2022. That‘s over 4 times faster than the median mobile upload speed of 4.32 Mbps.

In other words, Wi-Fi is almost always faster for iCloud backups than cellular data. Connect to a modern, uncongested Wi-Fi network for the speediest uploads. Avoid public Wi-Fi hotspots, which can be slow and unreliable.

If you don‘t have fast Wi-Fi at home, consider taking your iPhone to the office, school, or a friend‘s house to use their network for backups. Just make sure to get permission first.

Limit other internet usage during backups

Simultaneous downloads, video calls, and other internet activity can steal precious upload bandwidth from your iCloud backup. Pause or reschedule discretionary internet usage for faster backups.

If multiple devices are backing up to iCloud at once, consider staggering the backup times so each one can upload at maximum speed. You may need to coordinate with family members or housemates.

Keep your iPhone powered on and plugged in

iCloud backups only occur when your iPhone is connected to power, locked, and on Wi-Fi. If any of those conditions stops being true, the backup pauses until they‘re met again.

To ensure your backup completes as quickly as possible, keep your iPhone plugged in and on stable Wi-Fi until it finishes. Avoid using your iPhone during backups, as the process pauses every time you unlock your screen.

For fastest results, start a backup manually in Settings > iCloud > iCloud Backup, then tap Back Up Now. Stay connected to power and Wi-Fi until the backup finishes.

Projecting iCloud Backup Times: A Mathematical Approach

Armed with your backup size and upload speed, you can estimate how long a full iCloud backup will take using this formula:

Backup Time (hours) = Backup Size (GB) / Upload Speed (Mbps) * 8,192 seconds/GB

For example, if your iCloud backup is 8 GB and your Wi-Fi upload speed is 10 Mbps, the math works out like this:

Backup Time = 8 GB / 10 Mbps * 8,192 s/GB
= 6,553 seconds
= 1.82 hours

Keep in mind this is a best-case estimate. Real-world factors like fluctuating speeds, transmission overhead, and server load can extend backup times.

Use an online calculator like MegaConverter to explore how different backup sizes and upload speeds affect total backup time. Experiment with the optimization techniques above to improve your numbers.

When All Else Fails: Back Up to a Computer Instead

If you need to back up your iPhone immediately and iCloud is taking too long, you can always fall back on the wired backup method: connecting your iPhone to a Mac or PC with a USB cable and backing up using Finder or iTunes.

Wired backups are generally much faster than iCloud, since the data transfers over USB instead of the internet. However, they require having a computer handy and enough free storage space for the backup.

Wired backups also lack iCloud‘s automatic convenience—you‘ll need to remember to do them manually and keep your computer backed up as well for full redundancy.

If you do resort to a wired backup in a pinch, I still recommend re-enabling iCloud backups when you have more time. Having an automatic offsite backup is invaluable for worst-case scenarios like theft, loss, or disaster.

The Bottom Line

As a long-time Mac and iOS software consultant, my first-hand experience and industry data agree: These two strategies are the most effective way to speed up iCloud backups.

To recap, you can minimize iCloud backup sizes by:

1. Deleting unused apps and data
2. Disabling unnecessary app backups
3. Enabling iCloud Photos
4. Clearing out old messages and attachments

And maximize upload speeds by:

1. Connecting to fast, uncongested Wi-Fi
2. Limiting internet usage during backups
3. Keeping your iPhone powered on and plugged in

I recommend performing these iCloud optimizations periodically, perhaps at the start of each year or season. The more you stay on top of iCloud hygiene, the less painful backups will be.

But the ultimate iCloud backup tip is this: do it regularly, no matter what. Set a recurring reminder to plug in your iPhone overnight if needed. Check that backups are completing successfully.

Don‘t put off backing up until it‘s too late. The peace of mind of having an up-to-date iCloud backup is worth the time and effort. Your future self will thank you.
