How to Back Up Your iPhone Before It Dies

Your iPhone is acting up and you know it's not going to last much longer. Maybe the battery is swelling and the screen is lifting. Maybe it's randomly restarting. Maybe you dropped it in water and it's working now but you know that could change any second. Whatever the reason, you need to get your data off this phone now, before it turns into a very expensive paperweight.

The good news is that iPhones have excellent backup options built right in. If your phone can still turn on and respond to touch, you can back up everything (photos, texts, contacts, app data, health data, all of it) in a few minutes. The bad news is that once an iPhone is truly dead, getting data off of it is extremely difficult and sometimes impossible due to Apple's hardware encryption. And if your phone gets locked out with "iPhone Unavailable" after too many wrong passcode attempts, the data is gone for good on iOS 13 and newer. That's why acting now matters so much.

We're MDrepairs, a professional data recovery lab in New Jersey. We regularly see iPhones that people "meant to back up" but didn't get around to. Don't be that person. If your iPhone is showing any signs of trouble, do this today.

Signs Your iPhone Is About to Die

If you're seeing any of these, back up your data today. Not tomorrow. Today.

Battery Problems

• Battery health below 80%. Check at Settings > Battery > Battery Health. Below 80%, Apple considers the battery "significantly degraded."
• Phone dies at 30% or 40%. The battery gauge is unreliable because the battery can't hold the charge it reports.
• Swelling battery. If the screen is lifting away from the frame or there's a visible bulge on the back, the battery is swelling. This is a safety hazard. Back up and stop using the phone immediately.
• Phone gets extremely hot during normal use. A phone that's too hot to hold during a regular call or while scrolling social media has a battery or logic board issue.

Screen Problems

• Lines across the display. Horizontal or vertical lines that don't go away after restart mean the display connection or GPU is failing.
• Touch not responding in certain areas. If parts of the screen don't register touch, the digitizer is going. Today it's one corner. Tomorrow it might be the whole screen.
• Screen flickering. Intermittent flickering means the display cable or connector is loosening. It'll get worse.

Software Problems

• Random restarts. The phone reboots itself without warning. This can indicate logic board failure, NAND storage issues, or critical software corruption. If it starts restarting in a loop, you may be dealing with a disabled iPhone scenario if wrong passcodes get entered during the restarts.
• Apps crashing constantly. Not just one app, but multiple apps crashing regularly. Could be storage failure causing corrupted app data.
• Phone getting stuck on the Apple logo. If it's happening intermittently (sometimes boots, sometimes doesn't), the storage or logic board is failing.

How to Back Up to iCloud (Fastest)

This is the fastest way to get everything saved. If your iPhone is on and responsive, an iCloud backup takes about 10-30 minutes on Wi-Fi (depending on how much data you have).

What iCloud Backup Includes

How to Back Up to Your Computer

A computer backup (through Finder on Mac or iTunes on Windows) is the most complete backup option. It saves everything, and if you choose encrypted backup, it also saves your passwords, Health data, and Wi-Fi settings.

On Mac (macOS Catalina and later)

On Windows

Save Your Photos First (They're Irreplaceable)

If your phone is in bad shape and you're worried it might die any minute, prioritize photos. Everything else (apps, settings, contacts) can usually be recovered through iCloud or re-downloaded. But photos and videos that exist only on this phone are gone forever if the phone dies without a backup. We explain exactly why in our guide on recovering deleted iPhone data.

Option 1: iCloud Photos (Automatic)

Go to Settings > [Your Name] > iCloud > Photos. Turn on iCloud Photos. Your entire photo library will start uploading to iCloud over Wi-Fi. This is the hands-off approach, but it requires enough iCloud storage space and can take a while for large libraries.

Option 2: AirDrop to a Mac (Fast)

If you have a Mac nearby, open the Photos app on your iPhone. Select all the photos you want to save (tap "Select" then tap each photo, or select by date). Tap the Share button, then AirDrop to your Mac. AirDrop is fast (transfers over direct Wi-Fi) and doesn't require internet.

Option 3: Google Photos (Free Backup)

Download the Google Photos app from the App Store. Sign in with a Google account. Open the app and let it back up your photos. Google gives you 15GB free, which is more than iCloud's 5GB. The photos are stored at slightly reduced quality (but still perfectly fine for viewing and sharing) unless you pay for Google One storage.

Option 4: Email or Text Yourself

If you only have a few critical photos and nothing else is working, email them to yourself or text them to another phone number you have access to. Not elegant, but it works in a pinch. iMessage preserves photo quality. Email and SMS may compress them.

Option 5: USB to Computer

Connect your iPhone to any computer with a USB cable. On Windows, the iPhone appears as a camera in File Explorer. Navigate to DCIM folders and copy all photos and videos to the computer. On Mac, open the Photos app or Image Capture, select the iPhone, and import everything.

How to Save Contacts and Text Messages

Contacts

If you use iCloud Contacts (Settings > [Your Name] > iCloud > Contacts is toggled on), your contacts are already synced to iCloud. They'll automatically appear on any new iPhone you sign in to with the same Apple ID. You don't need to do anything extra.

If iCloud Contacts is off, turn it on now. It syncs almost instantly. You can also export contacts by emailing a vCard to yourself: Contacts app > select a contact > Share Contact > Mail.

Text Messages

iMessages and SMS texts are included in both iCloud backups and computer backups. If you want them synced in real time, go to Settings > [Your Name] > iCloud > Messages and turn it on. This stores your message history in iCloud and syncs it across all your Apple devices.

For a permanent archive of specific important conversations, take screenshots or use a third-party tool like iMazing (Mac/Windows, $40) to export conversations as PDF or text files.

How to Back Up WhatsApp and Other Apps

WhatsApp

WhatsApp has its own backup system separate from iCloud backup. Open WhatsApp > Settings > Chats > Chat Backup > Back Up Now. This backs up to iCloud. Make sure you have enough iCloud storage. WhatsApp backups can be large if you have a lot of media in your chats.

Other Apps with Their Own Backup

• Signal: Settings > Chats > Chat Backups (requires a 30-digit passphrase)
• Telegram: Cloud-based by default. Your messages are already stored on Telegram's servers (except Secret Chats).
• Notes: If iCloud Notes is on, they're already synced. If not, turn it on now at Settings > [Your Name] > iCloud > Notes.
• Authenticator apps (Google Authenticator, Authy): This is critical. If you use Google Authenticator, export your accounts (tap the three dots > Export accounts > screenshot the QR codes). Authy syncs to the cloud automatically. Losing your 2FA codes can lock you out of accounts permanently.

How to Back Up with a Cracked Screen

A cracked screen that still responds to touch works the same as a normal screen for backup purposes. Just follow the iCloud or computer backup steps above.

But if the screen is cracked AND doesn't respond to touch (you can see the display but can't tap anything), you've got a problem. Here's what to try:

Option 1: Use a Lightning/USB-C Keyboard or Mouse

You can connect a USB keyboard or mouse to your iPhone using a Lightning-to-USB adapter (or USB-C adapter for iPhone 15+). This gives you an alternative input method. You can navigate the phone with the mouse/keyboard and initiate a backup. You'll need to have already trusted a computer to do a wired backup, though. If you haven't, you'll need to tap "Trust" on the phone screen, which brings us back to the touch problem.

Option 2: Voice Control

If Voice Control was already enabled before the screen broke (Settings > Accessibility > Voice Control), you can use voice commands to navigate the phone. Say "Go to Settings" to open Settings, then use voice commands to navigate to iCloud Backup. If Voice Control wasn't already enabled, you can try asking Siri: "Turn on Voice Control."

Option 3: Use a Previously Trusted Computer

If you've previously connected your iPhone to a computer and tapped "Trust," that trust relationship is remembered. Connect the phone to that same computer, and it'll be recognized without needing to tap anything on the phone. Then run a backup through Finder or iTunes normally.

Option 4: Siri

Siri can help with some tasks when the screen is unresponsive: "Hey Siri, turn on iCloud backup" or "Hey Siri, open Settings." Siri can't tap buttons for you, but it can open apps and toggle some settings.

What If Your iPhone Won't Turn On

If your iPhone is completely dead (won't respond to anything, no screen display, no sounds, no vibrations), your backup options are limited. Here's what to try before calling a professional:

Try Charging It

Plug it into a known-good charger and cable. Leave it for at least 30 minutes. A completely dead battery needs time to charge enough to show any signs of life. Try different cables and chargers. If the phone vibrates after a while or shows the charging indicator, let it charge to at least 20% before trying anything.

Try a Hard Reset

A hard reset forces the iPhone to restart without needing the screen to work:

• iPhone 8 and later: Press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until you see the Apple logo.
• iPhone 7: Hold Volume Down + Side button together until you see the Apple logo.
• iPhone 6s and earlier: Hold Home + Side button together until you see the Apple logo.

Try DFU Mode

DFU (Device Firmware Update) mode is the lowest-level mode an iPhone can enter. It bypasses the operating system entirely. If DFU mode works but normal boot doesn't, there might be a software issue that can be fixed. However, DFU mode by itself doesn't let you back up data. It's mainly useful for restoring or repairing the iOS installation.

Check if iCloud Already Has Your Data

Before assuming everything is lost, check what's already in iCloud. Log into icloud.com from a computer and check Photos, Contacts, Notes, and other iCloud-synced data. If you had iCloud backup enabled and the phone backed up recently (check Settings on iCloud.com), most of your data might already be safe.

Professional Data Recovery

If the phone is truly dead and you don't have a backup, professional data recovery is your last option. iPhone data recovery is one of the hardest types of recovery because of Apple's hardware-level encryption. We'll be honest with you about what's possible. Check our iPhone data recovery guide for the full picture.

Backup Tips for Common Emergency Situations

Water Damage

If your phone got wet and is still working, back up immediately. Don't turn it off. Don't try to "dry it out in rice" (that doesn't work). Do the backup first, because water damage often has a delayed effect. The phone might work fine for hours or even days, then suddenly die as corrosion sets in. Get your data out while it's still working.

Swelling Battery

Keep the phone plugged in (the battery might not hold a charge), do the backup as fast as possible, then take it to a repair shop for battery replacement. Don't sleep with a swelling-battery phone near your bed. Don't put it in your pocket. It's a fire hazard.

Getting a New Phone Tomorrow

Do both an iCloud backup AND a computer backup tonight. Belt and suspenders. The iCloud backup is your primary transfer method (during new phone setup, choose "Restore from iCloud Backup"). The computer backup is your safety net in case iCloud has issues.

Phone Is Being Repaired

Always back up before sending your phone in for repair. Apple explicitly warns that repairs may result in data loss. Third-party repair shops should too. If your phone gets wiped during repair without a backup, recovering data after a factory reset is nearly impossible on modern iPhones. Back up, then hand over the phone. If the repair goes wrong, you haven't lost anything.

What to Do After You've Backed Up

Verify the Backup

Don't just assume it worked. For iCloud: Settings > [Your Name] > iCloud > iCloud Backup should show today's date. For computer backups: On Mac, open Finder, click your iPhone, and check "Last Backup" date. On Windows, iTunes > Device Preferences > Device Backups shows all backup dates.

Test the Backup (If Possible)

If you're transferring to a new phone, this is the test. Set up the new phone and restore from backup. Make sure your photos, messages, app data, and settings all come through. If something's missing, you still have the old phone to get it from.

Consider What's NOT in Your Backup

Some data isn't captured by standard backups:

• Apps themselves (they're re-downloaded from the App Store, so make sure you know your Apple ID password)
• Apple Pay cards (you'll need to re-add them)
• Banking app authentication (you'll need to re-verify with your bank)
• App-specific data that uses its own backup system (WhatsApp, Signal, etc.)
• 2FA codes in standalone authenticator apps (export these separately)

The best backup is the one you already have. The worst time to learn about backups is when you need one and don't have it. Set up automatic iCloud backups and never think about it again. Your future self will thank you.

Frequently Asked Questions

How long does an iPhone backup take?

It depends on how much data you have and your connection speed. An iCloud backup over Wi-Fi typically takes 10-30 minutes for most people. A computer backup over USB takes 10 minutes to an hour. Your first backup takes the longest because it's backing up everything. Subsequent backups are incremental (only new/changed data) and are much faster.

Can I back up my iPhone without Wi-Fi?

Not to iCloud. iCloud backups require Wi-Fi. But you can back up to a computer using a USB cable without any internet connection at all. If you don't have Wi-Fi, the computer backup is your best option.

What's the difference between iCloud backup and iCloud sync?

iCloud sync (Photos, Contacts, Notes, etc.) keeps specific types of data continuously synced to iCloud. iCloud backup captures everything else (app data, settings, messages, etc.) as a snapshot. They're complementary. Even with iCloud sync turned on for photos and contacts, you should still do regular iCloud backups to capture everything sync doesn't cover.

Can I back up my iPhone if the screen is completely black?

If the phone is on (you can hear sounds, feel vibrations) but the screen is black, try connecting to a computer you've previously trusted. The backup can happen without any screen interaction if the trust relationship already exists. If you haven't previously trusted a computer, you'll need to get the screen repaired first because you need to tap "Trust" on the phone screen.

How do I back up my iPhone with a broken charging port?

If the Lightning or USB-C port is broken, iCloud backup over Wi-Fi is your only option. Make sure you have enough battery life and iCloud storage. If the port is broken AND the battery is dead, you'll need professional repair before you can back up.

Is it worth paying for extra iCloud storage for a backup?

Absolutely. 50GB costs $0.99/month. 200GB costs $2.99/month. Compare that to the cost of losing all your photos, messages, and app data. It's the cheapest insurance you can buy. You can always downgrade your plan after you've transferred your data to a new device.

What if I forgot my iPhone backup password?

If you encrypted your computer backup and forgot the password, you can't restore from that specific backup. Apple can't help you recover it. But you can still do a new iCloud backup (which uses your Apple ID password, not the computer backup password) or create a new computer backup with a different password. The old encrypted backup is locked, but you can create new ones.
