Here's the honest version: the large majority of repairs — a cracked screen, a tired battery, a worn charging port, a dusty fan — never touch your files. The device comes back with everything where you left it.
But "almost always fine" isn't "guaranteed," and a backup is cheap insurance. If anything ever goes sideways — or if the repair turns out to need a software reinstall — a backup makes it a non-event instead of a heartbreak.
Does my repair actually touch my data?
Usually not. It helps to know which side of the line your repair falls on:
- Almost never touches data: screen replacement, battery replacement, charging port, camera, speaker, button, laptop fan or thermal service, keyboard.
- Might involve data: a device that won't boot, a phone stuck in a boot loop, water damage, or anything where the storage or software is the actual problem.
- Planned data work: data recovery, a clean OS reinstall, or migrating to a new device — here data is the whole point, and it's discussed first.
What to back up
Prioritize the things you can't simply re-download:
- Photos and videos — almost always the irreplaceable ones.
- Contacts, messages, and notes.
- Documents and downloads — especially on a laptop, the Desktop and Documents folders.
- Two-factor authenticator apps — note your recovery codes so you're not locked out if the device is ever reset.
- Passwords — make sure they're in iCloud Keychain, a password manager, or written down.
Apps, music, and anything already in the cloud can be re-downloaded, so they're lower priority.
How to back up, by device
- iPhone / iPad: Settings → your name → iCloud → iCloud Backup → Back Up Now (needs Wi-Fi and enough iCloud space). Or plug into a computer and back up locally with Finder (Mac) or the Apple Devices app (Windows) — tick "encrypt" to include passwords and health data.
- Android: Settings → Google → Backup → Back up now syncs photos, contacts, apps, and settings to your Google account. For full control, also copy photos off over a USB cable.
- Mac: Time Machine to an external drive is simplest — System Settings → General → Time Machine → add a disk. No external drive? At least copy your Desktop, Documents, and Photos library somewhere safe.
- Windows: Turn on File History to an external drive, or simply copy your important folders (Desktop, Documents, Pictures) onto a USB drive or cloud storage.
If the device won't turn on
You can't back up a device that won't power on — and that's okay. Bring it in as it is. In a lot of "dead" devices the storage is perfectly fine and the problem is a battery, a port, or a board issue; once it powers on, your data is right there.
If the storage itself is the problem, that's data recovery — a separate, careful process that gets explained before anything is done. Either way, don't keep forcing a device that won't boot to restart over and over; if data matters, that can make recovery harder. See data recovery for what that looks like.
Passcodes, Find My, and accounts
- Passcode: for repairs that need testing (touch, cameras, Face ID, charging), leaving the passcode lets the work be verified before pickup. You can change it afterward.
- Find My / activation lock: you usually don't need to turn this off for a screen or battery repair, but for some board-level work or a resale it matters — you'll be told if it does.
- Sensitive devices: if a device holds especially private data, back up and sign out of sensitive accounts first for your own peace of mind. See Is my data safe during repair? for how that's handled.
FAQ
Will I lose my data during a repair?
For most common repairs — screen, battery, charging port, fans — your data isn't touched and comes back exactly as it was. Data is only at higher risk when the device won't power on, the storage is the problem, or a full software reinstall is required. A quick backup first means you're covered no matter what.
Do I need to give you my passcode?
For many repairs, no. For anything that needs the device powered on and tested — touch, cameras, Face ID, charging — a passcode lets the repair be verified before you pick it up. You can change it afterward, and you're welcome to back up and sign out of sensitive accounts first.
How long does a backup take?
A phone backup over Wi-Fi is usually a few minutes to half an hour depending on how many photos you have. A first-time computer backup to an external drive can take longer, but you only wait for the first one. Start it before you head over and it's usually done by the time you arrive.
I don't have iCloud or Google storage space — what now?
Back up to a computer or an external/USB drive instead — it's free and often faster. For a phone, plugging into a computer backs up locally without needing cloud space. If you're stuck, text me and I'll walk you through the quickest option for your device.
