A factory reset on a Samsung Galaxy S5 typically takes between 5 and 15 minutes. The exact time depends on the reset method, the amount of data stored, and the device’s condition, but most users see the process complete within that window.
What Happens During a Factory Reset
A factory reset, also known as a hard reset or master reset, restores the Galaxy S5 to its original out-of-the-box state. The process erases all user data, including apps, photos, messages, and settings, then reinstalls the operating system from a hidden recovery partition. The time it takes is mostly consumed by two phases: wiping the data and rebooting. The wipe itself is quick—often under a minute—but the subsequent reboot can take several minutes as the phone rebuilds its system files and optimizes apps.
Methods to Reset a Galaxy S5
There are two primary ways to factory reset a Galaxy S5, and they differ slightly in time and steps.
- Settings menu reset: Go to Settings > Backup and reset > Factory data reset > Reset device. This method is straightforward and typically takes 5–10 minutes. The phone will restart and show the Samsung logo for a longer period than usual.
- Recovery mode reset: Power off the phone, then press and hold Volume Up, Home, and Power buttons simultaneously until the Samsung logo appears. Use the volume keys to navigate to Wipe data/factory reset, press the power button to select, confirm with Yes, and then select Reboot system now. This method is used when the phone won’t boot or the screen is locked. It takes about the same time, but the manual navigation adds a minute or two.
Both methods perform the same core operation, so the time difference is minimal.
Factors That Affect Reset Time
Several variables can make the reset take longer or shorter than the average.
- Amount of data: A phone with 64 GB of photos and videos will take longer to wipe than one with 10 GB. The erase process must overwrite or mark all storage blocks as free.
- Battery level: Samsung devices often refuse to reset if the battery is below 30% to prevent interruption. If the phone is low, you’ll need to charge it first, adding time.
- Software version: Later Android updates for the Galaxy S5 (up to Android 6.0.1 Marshmallow) may have slightly different reset routines, but the difference is negligible.
- Internal storage health: If the flash memory has degraded or has bad sectors, the wipe can take longer as the system retries reads and writes.
- First boot after reset: The initial boot after reset can take 2–5 minutes because the system rebuilds caches and prepares the setup wizard. This is often the longest part of the whole process.
How to Speed Up the Reset
While you can’t skip the reset itself, you can reduce the time around it.
- Back up first, then remove heavy data: If you back up photos and videos to a computer or cloud and delete them from the phone before resetting, the wipe will be faster. However, this is optional and not required.
- Ensure a full battery: Charge to at least 70% to avoid any low-battery warnings that might delay the process.
- Use the Settings method if possible: It’s slightly faster because you don’t have to navigate the recovery menu manually.
- Disable encryption: If you had enabled full-device encryption, the reset might take longer because the system has to decrypt and then erase. However, encryption is rarely enabled on the S5 by default.
Common Problems and Solutions
Sometimes the reset doesn’t go as smoothly, and users report issues that add time or cause concern.
- Stuck on Samsung logo: If the phone stays on the logo for more than 15 minutes, the reset may have failed. Try performing the reset again via recovery mode. If it still hangs, you may need to use Samsung’s Smart Switch software on a PC to do an emergency recovery.
- Reset loop: The phone restarts repeatedly after reset. This usually indicates a corrupted system partition. Boot into recovery mode and select Wipe cache partition first, then try the factory reset again.
- Phone asks for a Google account password: This is Factory Reset Protection (FRP). It’s a security feature, not a problem. You’ll need to enter the Google account credentials that were previously synced on the device. This doesn’t affect the reset time, but it can add minutes if you’ve forgotten the password.
What to Do After the Reset
Once the reset completes, the phone will boot to the setup wizard. This is not part of the reset itself, but it’s part of the overall process from start to finish.
- Setup wizard: You’ll choose a language, connect to Wi-Fi, and sign in with a Google account. This can take 5–10 minutes if you have a slow connection or two-factor authentication.
- Restoring data: If you restore from a backup, the time depends on the backup size and internet speed. A 20 GB backup can take over an hour.
- Updating apps: The Play Store will automatically reinstall apps. This can take 15–30 minutes for a typical user, but you can skip it and install apps manually later.
Is 30 Minutes Normal?
If your reset takes more than 20 minutes without any progress, something is likely wrong. The vast majority of resets finish in under 15 minutes. A 30-minute reset could indicate a failing storage chip, a corrupted recovery partition, or a hardware issue. In such cases, try the following:
- Hold the power button for 10 seconds to force a restart.
- Boot into recovery mode and try the reset again.
- If it still hangs, connect to a computer and use Smart Switch to perform a firmware initialization.
- If none of that works, the phone may need professional repair, as the storage could be failing.
Frequently Asked Questions
Will a factory reset speed up my Galaxy S5?
Yes, if the slowdown was caused by clutter, too many apps, or corrupted data, a reset will restore the phone to its original performance. However, the Galaxy S5 is an older device, and newer apps may still run slowly due to hardware limitations.
Do I need to remove the SIM card or SD card before resetting?
No, a factory reset does not erase the SIM card or SD card. However, if you want to wipe the SD card too, you must do that separately. Some users remove the SD card to avoid accidentally formatting it, but it’s not required.
Can I recover data after a factory reset?
Generally, no. The reset permanently deletes data, and recovery is nearly impossible without prior backup. Some forensic tools might recover fragments, but for practical purposes, consider all data gone.
How long does the battery last during a reset?
The reset process consumes battery, but not excessively. A full reset might use 5–10% of battery. If your battery is already low, it’s best to charge before starting.
Is it safe to interrupt a factory reset?
No. Interrupting a reset can corrupt the system and leave the phone in a non-bootable state. Always let it finish, even if it seems stuck. If it truly hangs for over 30 minutes, then force a restart and try recovery mode.
