Many users are faced with the need to return the device to its factory state, but often postpone the procedure for fear of a long wait or loss of important data. The question “how long does it take to reset settings on Android” is one of the most common in technical support, since the duration of the process can vary from a couple of minutes to several hours. The exact answer depends on many factors, including the amount of internal memory, file system type, processor performance and the chosen cleaning method.
On average, if you perform a standard reset through the settings menu on a modern smartphone with about 32-64 GB of free memory, the entire process will take from 10 to 20 minutes. However, if the device was filled to capacity with photos, application cache and heavy files, the time may increase to 40-50 minutes. It is important to understand that during this time the phone will be completely inaccessible, and the screen may go dark and light up several times - this is normal system behavior when formatting partitions.
There is a critical difference between simply deleting data and full formatting with encryption. On new versions Android 12 and higher, the system uses more complex protection algorithms, which may slightly increase processing time. If you plan to sell the device or give it to another person, you need to take into account not only the cleaning time itself, but also the subsequent initial setup, which will also require about 15 minutes of your time.
Factors influencing the duration of the cleaning process
The main parameter that determines the speed of the reset wizard is the amount of recorded information. The algorithm does not simply delete links to files, as the recycle bin does on a computer, but often carries out the procedure of erasing data or re-encrypting the partition userdata. The more gigabytes occupied, the longer the memory controller will take to perform I/O operations. On budget models with slow eMMC flash memory, this process can take disproportionately long compared to flagships with UFS 3.1.
⚠️ Attention: If the progress bar is stuck in one place for more than 30 minutes, and the device is hot, do not rush to reboot it with the power button. In some cases, the system conducts a deep integrity check of memory sectors, which is a normal situation for older drives.
The second important factor is the version of the operating system and the availability of security updates. In older versions, for example, in Android, for example, in Android 6.0 or 7.0, the reset procedure was simpler and faster, since it did not require complex cryptographic processing of encryption keys. Modern shells from manufacturers, such as Samsung or Xiaomi, add their own checks before starting the procedure, which also adds a few minutes to the total waiting time. The technical condition of the battery plays an important role. The system automatically checks the charge level before starting critical operations. If the charge is below 30%, the process may not start at all, or the system will artificially limit processor performance to save power, which will lead to longer reset times. It is recommended to always connect the device to the network or make sure that the battery is charged at least 50-60%. OneUI from Samsung or MIUI from Xiaomi add their own checks before starting the procedure, which also adds a few minutes to the total waiting time.

Comparison of reset methods: settings menu and Recovery Mode
Users can choose one of two main methods for returning to factory settings, and the execution time may vary. The first method is a soft reset through the operating system interface. You go to Settings → System → Reset settings and confirm the action. This method is usually faster, since the system is already loaded, the drivers are active, and the processor does not need to waste resources initializing the hardware from scratch.
The second method is to use recovery mode Recovery Mode. This option is necessary if the phone freezes, does not turn on, or the pattern key is forgotten. This mode is entered by using a combination of physical buttons (usually volume up and power button). Here the system operates in a minimalistic environment, without graphic effects and unnecessary services. Paradoxically, on some devices, resetting via Recovery is even faster, since there is no overhead from a running user interface.
| Comparison parameter | Reset via Settings | Reset via Recovery | Reset via ADB (PC) |
|---|---|---|---|
| Average time | 10-20 minutes | 15-25 minutes | 5-15 minutes |
| Requires screen to be turned on | Yes | No | No |
| Complexity for the user | Low | Average | High |
| Risk of error | Minimum | Medium | High |
There is also a third, more advanced method - resetting via a computer using USB debugging and console ADB. The command adb reboot recovery switches the device to the desired mode, and further sending of the formatting command occurs almost instantly from the user’s point of view, although the procedure itself takes standard time on the phone. This method is often used by service centers for mass flashing of devices.
☑️ Preparing for a full reset
Stages of the formatting process and what happens inside
To understand where the time goes, you need to break the process down into stages. After pressing the confirmation button, the system does not immediately begin erasing data. First there is preparation: ending all background processes, closing applications and saving error logs. This stage can take from 1 to 3 minutes depending on the number of running services.
Then comes the main stage - formatting the data section. At this point, the manufacturer's logo or robot animation often appears on the screen. The system goes through all memory sectors, marking them as free. If encryption is enabled, new cryptographic keys are generated. It is at this stage that the device may appear “dead” - the screen may go dark to save power, but the processor continues to work actively.
⚠️ Attention: During the formatting stage, it is strictly forbidden to remove the SIM card or microSD memory card if it has not been disabled by software in advance. This can lead to damage to the file system and the need to flash the device in the service.
The final stage is a reboot and initial initialization. Once the data is erased, the phone reboots as a new device. Here the system creates new system folders, checks the integrity of updates and launches the Welcome Wizard. This step usually takes about 3-5 minutes. If you see a screen with a language selection, then the hardest stage is already over.
Why can a reset take more than an hour?
If the process takes more than 60 minutes, the likely cause is the presence of bad sectors on the device’s flash memory. The memory controller tries to read or write the damaged block repeatedly, going into an infinite loop. In such a situation, the safest thing to do is wait until the battery drains, then try to enter Recovery mode and format from there. If this does not help, the intervention of a specialist with a programmer is required.
Features of reset on devices from different manufacturers
Different brands use their own implementations of the recovery menu and cleaning algorithms, which directly affects the speed. For example, smartphones Samsung with a shell One UI often perform an additional security check Knoxwhich adds several minutes to the process. Also, devices of this brand may require you to enter a password for your Samsung account before starting the procedure, which is a measure of protection against theft.
Devices from Xiaomi and Poco based on MIUI or HyperOS have their own specifics. If your phone has bootloader unlocking enabled or custom superuser permissions (Root) are set, a standard reset may not work correctly or may take significantly longer due to an attempt to wipe hidden partitions. In such cases, the system may issue a warning that the device will be locked after a reset.
“Clean” Android, which is installed on smartphones Google Pixel, Motorola i Nokia, usually demonstrates the highest reset speed. The absence of heavy add-ons and unnecessary pre-installed software allows the system to quickly free up resources and perform formatting. Here the process rarely exceeds 10-12 minutes even with completely full memory.
Before performing a reset, remove the microSD card. Although modern versions of Android ask if you need to format it too, physical extraction ensures that your personal photos and documents on the card are not accidentally deleted due to a script error.
Typical problems and freezes during reset
Sometimes users encounter a situation where the phone freezes at the logo or formatting stage. This could be caused by a software glitch, corrupted system files, or hardware failure. If the screen stays on for more than 40 minutes without changing, the process may actually be stuck. In this case, a safe method of intervention would be a forced reboot.
For most models, the combination of buttons for a forced reboot is holding down the power key for 10-15 seconds. However, after such intervention, the device may not boot into normal mode, but will immediately go to the Recovery menu. This is a normal system reaction to an incorrect shutdown. You will have to select the item Reboot system now or repeat the reset procedure (Wipe data/factory reset).
Another common problem is the bootloop after a reset. This often happens if the user tried to roll back to an older version of Android or if the partition files were damaged cache. In this case, a simple reset is not enough - it is required complete flashing of the device via a computer using official utilities, such as Odin for Samsung or SP Flash Tool for MediaTek processors.
⚠️ Attention: If after resetting the device requires entering a Google account (FRP Lock), which you do not remember, unlock the phone using legal methods without contacting the service receipt of purchase is almost impossible. Make sure you know your credentials before starting the procedure.
Stuck on the logo for more than 40 minutes is an anomaly. A standard reset should not last longer than an hour, even on the slowest devices with a large amount of data.
How to speed up the preparation and the process itself
Although the technical process itself It is impossible to speed up formatting, you can reduce the total time spent on the procedure through high-quality preparation. Before starting the reset, it is recommended to manually delete the heaviest files: high-resolution videos, disk images, downloaded maps for navigation. This will reduce the amount of data that the system will need to process and “overwrite.”
It is also worth disabling all unnecessary accounts except the main Google. synchronization. This will prevent the system from trying to synchronize data when the reset begins, which sometimes causes conflicts and delays. Freeing up RAM before the procedure will also give the system a small performance boost.
Using a fast charger indirectly affects the speed. If the phone does not go into power saving mode due to low battery, the processor can operate at the maximum frequencies allowed for this operation, which will ensure the fastest connection to the network. 220V guarantees voltage stability, which is important for the memory controller.
Myth about formatting via PC
There is an opinion that connecting the phone to a computer and formatting through a card reader will speed up the process. This is a dangerous misconception. Android internal memory is not detected as a regular flash drive, and an attempt to format it with third-party utilities on a PC will lead to the complete loss of the bootloader and the phone turning into a flash drive. “brick.”
Frequently asked questions (FAQ)
Is it possible to interrupt the reset if it takes too long?
It is highly not recommended to interrupt the process at the formatting stage, as this may damage the file system. If less than 10 minutes have passed, wait. If more. 40-50 minutes and the indicator does not move, you can try a forced reboot, but be prepared for the fact that the phone may not turn on without flashing.
Is data deleted from the memory card when resetting the phone?
By default, resetting the settings only affects the internal memory of the device. However, if you selected the option in the storage settings. “Format as internal memory”, then the card will be encrypted along with the phone and the data on it will become unreadable without this specific device.
How long does the reset take if the phone does not turn on?
If the phone does not turn on, you use the Recovery mode itself does not depend on whether the screen was turned on earlier. It will be the same 10-20 minutes. However, time will be added. to enter recovery mode and navigate using the volume buttons.
Do you need to remove the SIM card before resetting?
It is not necessary to remove the SIM card, the reset procedure does not affect it. However, contacts saved directly on the SIM card will not be deleted when resetting the phone, since they are stored on the card chip, and not in the memory. device.
Why is the phone running slower after the reset than before?
In the first 30-60 minutes after the reset, the system performs background optimization of applications and file indexing. During this time, the processor may be 100% loaded, and the battery may drain quickly. This is normal; performance will be restored after background tasks are completed.
