Why People Reset Their Phones and What That Means for Your Data
A phone reset is one of those tech procedures that sounds more complicated than it actually is. When you reset your phone, you're essentially returning it to the condition it was in when it first came from the factory. This wipes out everything stored on the device—your photos, messages, apps, contacts, passwords, browsing history, and any personal files you've saved.

People choose to reset their phones for different reasons. Some do it when they're selling or giving away an old device and want to protect their personal information. Others reset because their phone has started running slowly, freezing frequently, or acting strangely. Some people reset after experiencing a security concern, like accidentally downloading something suspicious. And occasionally, someone will reset their phone simply because they want a fresh start with a cleaner device.
The problem is that many people don't fully understand what happens during a reset, or they're not aware of the steps they need to take beforehand to protect their information. There's also confusion about different types of resets—some more thorough than others—and what data actually gets removed versus what might remain on the device. These questions matter because data left behind after a reset could expose personal information to whoever uses the phone next.
Understanding phone resets helps you make better decisions about when and how to reset your own device. It also prepares you to handle your data responsibly, whether you're keeping your phone or passing it along to someone else. This guide focuses on the information you need to know before, during, and after performing a phone reset.
Practical takeaway: Before doing anything to your phone, think through your reasons for wanting a reset and consider whether a reset is the right solution for your specific problem.
What Gets Removed During a Phone Reset and What Doesn't
This is where confusion typically starts. When people say "phone reset," they usually mean a factory reset—the most complete type of wipe available to regular users. A factory reset removes most of what you put on your phone after you first got it. That includes every app you downloaded, every message and email, all your photos and videos stored on the device itself, your contacts list, your calendar entries, notes, and custom settings like your wallpaper and home screen layout.

However, "most" is not the same as "everything." Several categories of information may survive a factory reset, and it's important to know this before you hand your phone to someone else or put it in storage. For example, if you've been using cloud services like Google Drive, OneDrive, iCloud, or Samsung Cloud, the files you synced to those services remain intact in your online accounts even after your phone is wiped. The phone itself no longer has them, but they still exist somewhere else. Similarly, your email accounts remain on your phone after a reset because they're tied to your account credentials, not to the phone's storage.
Passwords stored in your phone's password manager may or may not be deleted depending on your device type and settings. Some phones store these locally, while others sync them to a cloud account. Your phone's SIM card—the tiny chip that connects to your cellular network—holds certain information that typically doesn't get erased during a factory reset. This can include phone numbers and service information tied to your cellular provider. Additionally, data written deep into the phone's system storage may technically remain even after a reset, though it's very difficult for average people to access.
Different phone brands also handle resets differently. Android phones made by Samsung, Google, Motorola, and others have slight variations in what gets erased and how. iPhones have their own factory reset process. The key point is that a factory reset is not a complete data deletion—it's more accurate to think of it as removing the easy-to-access information that an average person would see when using the phone.
Practical takeaway: Before resetting your phone, sign out of all your cloud accounts and remove saved passwords to prevent someone else from accessing your information through those services after the reset.
Steps to Take Before You Reset Your Phone
Preparation makes the difference between a smooth reset and losing information you wanted to keep. The first step is to make a backup of anything you want to preserve. This is crucial because once a reset completes, you can't get that data back unless it was backed up somewhere. Most phones have automatic backup systems built in—Google Backup for Android phones and iCloud for iPhones—but you should verify these are actually turned on and working before you proceed.

Take time to back up manually as well. For photos and videos, you can copy them to a computer, upload them to cloud storage like Google Photos or Amazon Photos, or use your phone's native backup service. For contacts, you can export them to your email account or save them as a file. For documents and files, make sure they're uploaded to the cloud or transferred to a computer. This step takes maybe 30 minutes to an hour depending on how much data you have, but it's the one step that prevents permanent loss.
Next, sign out of all your accounts on the phone itself. This includes your email accounts, social media accounts, streaming services, and especially your main Google account (for Android) or Apple ID (for iPhones). When you remove your Google or Apple account from the phone before resetting, the phone's security features work differently than if that account is still present during the reset. Some people skip this step and then have trouble using their phone afterward because the security lock won't let them set it up properly.
You should also remove any saved payment methods and payment apps. If you have Apple Pay or Google Pay set up, disable it before the reset. If you have banking apps that store payment card information, remove that saved data through the app settings if possible. Check your phone's storage settings for any files you created or downloaded that you might have forgotten about—sometimes important documents or photos end up buried in folders. Write down any information you think you might need later, like Wi-Fi network names and passwords if you won't have access to them another way.
Finally, charge your phone to at least 50 percent battery before starting the reset process. A reset that gets interrupted by a dead battery can leave your phone in an unusable state. Some phones take 15 to 30 minutes to complete a full factory reset, so you need enough power for the entire process.
Practical takeaway: Create a simple checklist: backup data, sign out of accounts, remove payment methods, check for hidden files, then charge. Follow it in order, and you won't forget anything important.
How to Perform a Factory Reset on Android and iPhone Devices
The process differs between Android phones and iPhones, but the goal is the same: return your device to factory settings. For most Android phones, start by opening Settings and looking for a section called "System" or "About Phone." In that area, you'll find an option labeled "Reset Options," "Reset," or sometimes "Erase All Data." The exact name varies by manufacturer—Samsung calls it "Reset," while Google Pixel phones might say "System Reset." When you find this option and select it, the phone will ask you to confirm that you want to erase everything. This confirmation step exists to prevent accidental resets, so make sure you really want to proceed before confirming.

Some Android phones require you to enter your PIN, password, or pattern to confirm the reset. This is a security measure. After you confirm, the phone will begin the reset process. You'll typically see a progress bar or spinning animation. During this time, don't turn off your phone or interrupt the process. Your phone may restart automatically during the reset—this is normal. The entire process usually takes between 5 and 20 minutes depending on your phone model and how much data was on it.
For iPhones, the process starts in the Settings app under "General." Scroll to the bottom and look for "Reset" or "Transfer or Reset iPhone." You'll see several reset options—choose "Erase All Content and Settings." Before this will work, you may need to turn off Find My iPhone in your iCloud settings first. The phone will ask you to confirm your Apple ID password, and then it will begin the erase process. Like Android, the iPhone will show a progress indicator and may restart during the process. iPhone resets tend to be a bit faster than Android resets, often finishing in 10 to 15 minutes.
One important note: if you can't remember your phone's password or PIN, resetting becomes more complicated. You won't be able to perform a reset through settings because the phone requires authentication. In this situation, you'd need to look up your phone manufacturer
