Essential Preparation Steps Before Factory Resetting

Before proceeding with a factory reset, take these critical steps to protect your data:

1. Back Up Everything Important

This is the most crucial step. Ensure all your photos, videos, contacts, and important files are backed up either to cloud storage or to your computer3.

For iPhone users: Go to Settings > [your name] > iCloud > iCloud Backup and enable iCloud Backup.

For Android users: Go to Settings > System > Backup and ensure “Back up to Google Drive” is enabled.

2. Sign Out of All Accounts

Log out of your accounts, especially your Google or Apple ID. This prevents issues with Factory Reset Protection on Android devices or activation lock on iPhones. Failing to log out could cause you to miss incoming messages or create problems for new users.

3. Remove External Storage

If your phone has a removable SIM card or microSD card, remove them before resetting. This protects additional data and prevents complications during the reset process.

4. Charge Your Device

Ensure your device has at least 70% battery or is plugged in during the reset process. A factory reset can take up to an hour, and you don’t want your phone dying halfway through.

5. Note Your Credentials

Write down your Google or Apple account details as you’ll need them to set up your phone after the reset.

Why You Might Need to Factory Reset Your Phone

There are several compelling reasons why you’d want to perform a factory reset on your smartphone. According to a 2025 survey, Americans check their phones an average of 144 times daily and spend over four hours on their devices5. With such intensive usage, it’s no wonder our phones occasionally need a fresh start.

The most common scenarios for factory resetting include:

• Selling or trading in your device: A proper reset ensures all your personal data is wiped, protecting your privacy and security. Many users believe a standard factory reset is sufficient when disposing of a smartphone, but there are additional steps you should consider.
• Troubleshooting performance issues: If your phone is running slowly, freezing, or experiencing unusual glitches, a factory reset can often resolve these problems by clearing corrupted data and problematic apps. Experts recommend this as a last resort after trying other solutions.
• Forgotten passcode: When you’re locked out of your device and can’t remember your password or pattern, a factory reset might be your only option to regain access.
• Gifting your phone: If you’re passing your device to a family member or friend, a factory reset ensures they start with a clean slate without your personal information lingering.

What Actually Gets Deleted During a Factory Reset

A factory reset (also called formatting or hard reset) is a complete wipe of your device’s internal storage. When you perform this operation, the following data will be permanently erased:

• Contacts
• Photos and videos
• Music and audio files
• Passwords and saved credentials
• All accounts and login information
• Messages (SMS, WhatsApp, etc.)
• Apps and their associated data
• Personal settings and preferences

It’s crucial to understand the difference between various reset types. A soft reset simply restarts your phone without affecting your data, while a hard reset forces your device to reboot, which can fix minor bugs. A factory reset is the most comprehensive, completely wiping all data and returning the phone to its original state.
