Introduction

Keeping your phone updated is important for security, performance, and new features. However, sometimes the update process doesn’t go as planned. One of the most common problems is when the software update gets stuck on “Calculating Time Remaining” and doesn’t seem to make any progress.

This issue can occur on both Android and iPhone devices and is usually caused by temporary problems such as a slow internet connection, insufficient storage, or server congestion.

Whether you use a Samsung Galaxy, Google Pixel, Xiaomi, Redmi, POCO, OnePlus, Motorola, Vivo, Oppo, Realme, or an iPhone, this guide explains why the update gets stuck and how to fix it safely without risking your data.

Why Does the Update Stay on “Calculating Time Remaining”?

When your phone displays “Calculating Time Remaining,” it is preparing to download or install the update.

During this stage, the device checks several things, including:

• Internet connection speed
• Available storage space
• Battery level
• Update file integrity
• Manufacturer or Apple update servers

If any of these checks fail or take too long, the progress may appear frozen.

Common Causes

Several factors can cause the update process to stall:

• Slow or unstable internet connection
• Low available storage
• Temporary server issues
• Corrupted update files
• Battery level too low
• VPN or network restrictions
• Background downloads consuming bandwidth
• Temporary software glitches

Fortunately, most of these issues are easy to fix.

Fix 1: Check Your Internet Connection

A stable internet connection is essential for downloading system updates.

If you’re using mobile data, switch to a reliable Wi-Fi network whenever possible.

You can also try:

• Restarting your Wi-Fi router.
• Moving closer to the router.
• Disconnecting other devices using the same network.
• Turning off VPN services temporarily.

After improving the connection, check whether the update resumes.

Fix 2: Free Up Storage Space

Software updates require enough free space not only for the download but also for extracting and installing temporary files.

Android

Go to:

Settings → Storage

iPhone

Go to:

Settings → General → iPhone Storage

Delete unnecessary:

• Photos and videos (after backing them up)
• Large downloads
• Unused apps
• Cached files (where applicable)

Keeping at least 10–20% of your storage free helps updates install more smoothly.

Fix 3: Charge Your Battery

Many phones delay or pause updates if the battery level is too low.

For best results:

• Charge your phone to at least 50%.
• Keep it plugged into the charger during the update if possible.

This helps prevent interruptions during installation.

Fix 4: Restart Your Device

A simple restart often resolves temporary software glitches affecting the update process.

After restarting:

1. Connect to Wi-Fi.
2. Check for updates again.
3. Restart the download if necessary.

Many stalled updates continue normally after a reboot.

Fix 5: Delete the Downloaded Update

Sometimes the downloaded update file becomes corrupted.

If your phone provides this option:

Android

Go to:

Settings → Software Update

or

Settings → Storage

Delete the downloaded update package if available.

iPhone

Go to:

Settings → General → iPhone Storage

Locate the downloaded iOS update (if listed), delete it, and download it again.

Downloading a fresh copy often resolves installation issues.

Fix 6: Update Using a Computer

If the update still won’t install, updating through a computer can help.

Android

Some manufacturers provide official update or recovery tools that can reinstall the latest software.

Examples include manufacturer-provided PC utilities for supported devices.

Always use official software designed for your phone model.

iPhone

Connect your iPhone to a computer and use:

• Finder (macOS)
• Apple Devices (current Windows versions)
• iTunes (older Windows systems)

These tools can download and install the latest iOS version directly.

Fix 7: Check for Server Problems

Sometimes the issue isn’t with your phone.

During major software releases, update servers may experience heavy traffic, causing delays.

If many users are downloading the update at the same time, waiting a few hours and trying again may solve the problem.

Fix 8: Disable VPN or Proxy Services

VPNs and certain network configurations can interfere with software downloads.

If you’re using:

• VPN
• Private DNS
• Proxy server

Temporarily disable them and try downloading the update again.

Fix 9: Reset Network Settings

If your internet connection appears normal but downloads repeatedly fail, resetting network settings may help.

Android

Settings → System → Reset → Reset Network Settings

iPhone

Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings

You’ll need to reconnect to Wi-Fi afterward.

Tips for Successful Software Updates

To avoid update problems in the future:

• Use a stable Wi-Fi connection.
• Keep at least 10–20% storage free.
• Charge the battery above 50%.
• Back up important data before major updates.
• Avoid interrupting the installation process.
• Install updates when your internet connection is reliable.

These simple steps reduce the chances of update failures.

Frequently Asked Questions

How long should “Calculating Time Remaining” take?

Normally, it lasts only a few minutes. If your phone remains on this screen for an extended period without progress, the update process may have stalled.

Will restarting my phone cancel the update?

If the update hasn’t begun installing yet, restarting usually won’t cause any problems. However, avoid restarting the device while the actual installation is in progress unless the phone is completely unresponsive.

Can low storage cause update problems?

Yes. Insufficient storage is one of the most common reasons software updates fail or become stuck.

Is it safe to delete the downloaded update?

Yes. If the downloaded update file is corrupted, deleting it and downloading a fresh copy is a common troubleshooting step.

Final Thoughts

A software update that remains stuck on “Calculating Time Remaining” is usually caused by a temporary issue rather than a serious hardware problem. In most cases, checking your internet connection, freeing up storage, restarting your phone, or downloading the update again is enough to get the installation moving.

If the problem continues, using your manufacturer’s official update tool for Android or updating your iPhone through Finder, Apple Devices, or iTunes can often complete the installation successfully. Keeping your phone charged, connected to a stable Wi-Fi network, and maintaining adequate free storage will help future updates install more smoothly.
