Can You Update iPhone While Charging? A Step-By-Step Guide
Explore whether you can safely update your iPhone while charging. This SoftLinked guide covers OTA vs wired updates, best practices, backup steps, and a clear, step-by-step process to keep your device powered and secure during installation.
Yes. You can safely update your iPhone while it's charging. Updates downloaded over Wi-Fi (OTA) can run while the device is plugged in, reducing interruption risk. For best results, keep the phone connected to power, ensure enough storage, and back up your data beforehand. If you prefer a computer-based update, keep the computer powered and the USB connection stable.
Understanding iOS Updates and Power Requirements
iPhone software updates, typically delivered as iOS updates, can be large and involve downloading files and installing changes that modify system components. Because these processes involve significant data transfer and temporary system activity, having a reliable power source helps prevent mid-update shutdowns. When you run updates while charging, your device has uninterrupted power, reducing the risk of an failed install. SoftLinked's analysis indicates that charging during updates is a common practice among developers and power users who want to minimize downtime. By planning to update while plugged in, you also reduce the chance of an update failing due to a depleted battery.
OTA Updates vs Desktop Updates: What Changes
Most iPhone updates are delivered over the air (OTA) through Settings > General > Software Update. OTA updates download the new software package to the device, then prompt you to install. Desktop updates, via iTunes or Finder on a computer, download the same package to the computer first and then install it onto the iPhone. Both methods require power and a stable connection. OTA is convenient because it doesn't require a computer, but a wired or stable Wi‑Fi connection and staying plugged in during the process remains essential for a smooth install. In practice, many users choose OTA for speed and convenience, while power users keep a computer handy for longer or more complex updates.
Safety and Battery Considerations
While charging during an update is generally safe, you should still consider a few safety practices. Ensure the charger and cable are in good condition to avoid intermittent power. If your iPhone gets unusually warm, pause the update and let it cool, then resume. Avoid charging from a laptop USB port if it cannot provide stable power; use a wall outlet instead. SoftLinked's research suggests that using a dedicated wall charger with a solid power rating reduces the risk of a mid-update shutdown. Never use makeshift cables or damaged adapters during updates, as irregular power can cause unexpected failures.
Backup Before Update
Before starting any iOS update, perform a backup of your data. iCloud backups are convenient and automatic, but a computer-based backup (via Finder on macOS or iTunes on Windows) provides an additional restore point. Backups protect against issues like incomplete installation, data corruption, or app incompatibilities. If you rely on photos or messages, ensure those are included in the backup. For peace of mind, confirm that your backup completed successfully before you begin the update.
Step-by-Step Overview (OTA) for Charging Scenarios
This section provides an overview of the OTA update flow when you are plugged in. The update process begins with a download, then verification, then installation. During the installation phase, the device may restart multiple times, and the screen may go dark briefly. Having power throughout prevents a partial install caused by a dropped battery. You should be prepared for the process to take some time, especially on larger iOS updates with new features and security patches.
Troubleshooting Common Update Issues While Charging
If an update stalls or shows an error, start with basic checks: verify you have a stable Wi‑Fi connection, confirm enough storage space, and ensure the device remains plugged in. If the progress bar is stuck, pause, cancel the download (if possible), and retry after a few minutes. A complete restart of the device can help in some cases, followed by retrying the update. If errors persist, consult Apple Support for specific guidance or revisit your backup to restore your data after a failed attempt.
Pro Tips for a Smooth Update
- Use a trusted Wi‑Fi network with good speed to download updates quickly. - Keep your device on a wall charger rather than a portable battery if possible to ensure stable power. - Turn off heavy background tasks during the update to allocate more resources to the install. - If updating overnight, ensure the device is securely plugged in and not in a reachable place where it could be disturbed. - After updating, review major settings (Privacy, Passcode, and Backup) to confirm everything migrated correctly.

Tools & Materials
- iPhone with latest iOS(Ensure you have sufficient storage for the update.)
- Wall charger(Prefer the original charger or a high-quality replacement.)
- Lightning to USB cable or USB-C cable(Use the cable that came with the device if possible.)
- Stable Wi-Fi connection(Avoid public or unstable networks; prefer 5 GHz if available.)
- Backup method(iCloud backup or computer backup (Finder/iTunes) before updating.)
- Optional computer for desktop update(Can be used if you prefer updating via Finder/iTunes.)
Steps
Estimated time: 60-90 minutes
- 1
Verify prerequisites
Check available storage, confirm device is on charger, and verify you’re connected to a stable Wi-Fi network. This reduces the risk of interruption during the update.
Tip: Free up at least a couple hundred megabytes beyond the update size to avoid space-related failures. - 2
Back up your data
Create a fresh backup using iCloud or Finder/iTunes. This ensures you can restore settings, apps, and data if something goes wrong during installation.
Tip: If possible, perform the backup over a fast network to speed up the process. - 3
Connect power and network
Plug the iPhone into a reliable power source and verify the charger remains connected throughout.
Tip: Avoid moving the device during the update to prevent accidental disconnections. - 4
Open Software Update
Navigate to Settings > General > Software Update to check for available updates and start the download.
Tip: If you see “Update Tonight,” you can choose to start now or schedule for later; power remains important regardless. - 5
Download and install
Tap Download and Install or Install Now, then enter your passcode if prompted. The device will restart automatically as the update installs.
Tip: Do not unplug or interrupt during the installation phase. - 6
Monitor progress
Let the update finish without interference. The screen may go dark during installation, and the device will restart one or more times.
Tip: If the update seems to stall for an extended period, pause and retry after a short while. - 7
Complete and verify
After installation, verify the iOS version in Settings > General > About. Confirm that key apps and features work as expected.
Tip: Re-enable any privacy or background settings you may have paused during the update. - 8
Finish with a fresh start
Open essential apps to confirm normal operation, then perform a quick data check (photos, messages, and notes) to ensure nothing is missing.
Tip: If issues appear, consult Apple Support with your backup handy.
