A factory reset wipes a phone, tablet, or laptop back to the state it was in when it left the shop. It can fix a device that keeps misbehaving, and it is essential before you sell or give away an old gadget. But learning how to factory reset a device singapore households rely on comes with one huge warning first: a reset erases everything on the device. Photos, messages, apps, and files are gone unless you have backed them up. This guide walks you through doing it carefully, in the right order, so you never lose something you cannot get back.
Take it slowly. A factory reset is not something to rush through on a whim. Read this whole guide before you tap anything.
Back Up Everything First (This Is Not Optional)
The single most important step happens before the reset, not during it. Once a factory reset starts, there is usually no way to recover what was on the device. So treat your backup as the thing that protects years of memories and important documents.
On a phone, back up your photos, contacts, messages, and app data. Both major phone systems have built-in cloud backup, and you can also copy photos to a computer or an external drive. Our guide on how to back up your phone properly walks through the settings step by step. On a laptop, save your files to an external drive or cloud storage, and check that the backup actually contains what you think it does. Open a few files to confirm they are really there.
A few things people forget to back up:
- Photos and videos, especially ones only stored on the device.
- WhatsApp chat history, which needs its own separate backup inside the app.
- Two-factor authentication apps, which may need to be moved to the new device before you wipe the old one.
- Notes, downloads, and files saved outside the main gallery.
If you are not sure whether something is backed up, assume it is not, and copy it somewhere safe. It is far better to have two copies than none.
Sign Out of Your Accounts and Remove Locks
This step is critical, and skipping it causes real headaches, especially if you plan to sell the device. Modern phones and laptops have an anti-theft feature that locks the device to your account. If you reset without signing out first, the next person, even a legitimate buyer, may be locked out and unable to use it.
Before you reset, do the following:
- Sign out of your main account. On an iPhone or iPad, turn off the activation lock by signing out of your Apple Account. On an Android phone, remove your Google account from the device.
- Sign out of other important accounts, such as your bank apps, email, and any account tied to payments.
- Remove your SIM card and any microSD card if you are passing the device on.
- Turn off any “find my device” tracking, which is usually switched off automatically when you sign out properly.
If you are getting a device ready for a new owner, spend a few extra minutes on security. Our guide on locking down your phone before selling it covers the account and privacy checks that matter most. Doing this protects both you and the buyer, and it keeps your data from ending up in the wrong hands.
How to Perform the Reset
Once your backup is done and your accounts are signed out, the reset itself is straightforward. The exact wording differs between devices, but the path is similar.
On most phones, open Settings, search for “reset”, and look for an option like “Erase all content and settings” or “Factory data reset”. The device will ask you to confirm, and it may ask for your passcode or account password. This is normal and is there to stop a stranger wiping your device. After you confirm, the device does the rest and restarts as if brand new.
On a laptop, both Windows and Mac have a built-in reset option in their settings. Windows calls it “Reset this PC” and offers a choice to remove everything. Mac has an “Erase All Content and Settings” option on newer models. Keep the charger plugged in throughout, because a reset can take a while and you do not want it interrupted by a flat battery.
A few safe habits during the reset:
- Keep the device plugged in to power the whole time.
- Do not force a restart or pull the plug midway, even if it seems slow.
- Stay connected to your home WiFi if the device asks, so it can verify your account.
After the Reset, and Disposing of Old Devices
If you reset the device to fix a problem, you can now sign back in and restore your backup. Set it up as you would a new device, then bring your data back from the cloud or your external drive. Restoring can take time, so be patient and stay on WiFi.
If you reset the device to retire it, think about where it goes next. A working phone or laptop can be sold or handed down. One you no longer want should not go into the general rubbish, because it contains materials that need proper handling. Drop it at a proper collection point through the national e-waste scheme instead. Our guide on e-waste recycling explains where the bins are and what they accept.
To wrap up, remember the order that keeps you safe. Back up everything and check the backup works. Sign out of your accounts and remove any activation lock. Only then perform the reset, with the device plugged in. Do it in that sequence and a factory reset becomes a clean, stress-free way to fix a device or pass it on, rather than a moment you regret.
