How to Update iPhone 5s via Wi-Fi: A Complete Guide with Solutions to Common Problems

iPhone 5s, released in 2013, remains a popular device among users who value compactness and reliability. However, with the release of new versions iOS Owners are faced with the question: how to update the firmware on an old smartphone if it only supports a limited list of versions? Update via Wi-Fi (over the air, OTA) is the most convenient way, but for iPhone 5s There are some nuances here: from iOS version restrictions to network requirements.

In this article, you'll find not only step-by-step instructions, but also solutions to common problems: from loading errors to freezing on the logo. AppleWe'll also look at how to optimize your home network for fast firmware downloads (up to 1.5–2 GB), and what to do if your device refuses to update due to insufficient memory. All recommendations are relevant for iPhone 5s with the original and replaced battery - taking into account the features of the old hardware.

⚠️ Important: iPhone 5s officially supports the maximum iOS 12.5.7 (Released in 2023 to fix security vulnerabilities). Install new versions of iOS on this device. No, hardware limitations block the upgrade to iOS 13 and above.If your smartphone is already running iOS 12.5.7, further over-the-air updates will only be available for critical security fixes (if any).

1. Check the current iOS version and compatibility

Before you begin updating, make sure that your iPhone 5s It really needs new firmware. To do this:

1. Open the app Settings.
2. Go to the section Main → About the program.
3. Look at the line Version — the current firmware is indicated there (for example, 12.5.6 or 12.5.7).

If the version is lower 12.5.7, an update is possible. If it's higher, your device is already running the latest supported firmware. Also check:

• 🔋 Battery charge: must be at least 50%. If the charge is low, the system will block the update.
• 📶 Wi-Fi connection: Mobile internet (3G/4G) is not suitable for downloading firmware - only a stable network is required.
• 📱 Free space: minimum required 2 GB free memory (check in Settings → General → iPhone Storage).

⚠️ Attention: If your iPhone 5s was jailbroken, updating via Wi-Fi may result in data loss or "bricked" (inoperable). In this case, it is recommended to first remove the jailbreak using special utilities (for example, Checkra1n or Unc0ver), and then updated.

2. Preparing your Wi-Fi network for fast downloads

Firmware for iPhone 5s weighs about 1.5–2 GB, and downloading it over unstable Wi-Fi may take hours or be interrupted. To avoid errors:

• 📡 Reconnect to the 5GHz network: If your router supports two bands (2.4 and 5 GHz), select 5 GHz — there is higher speed and less interference.
• 🔌 Use a wired connection to your router: If the router is connected to the internet via Wi-Fi (bridged mode), the speed will be lower. Connect it to your ISP via cable.
• 🚫 Disconnect other devices: Pause downloads on computers, smart TVs, and other devices connected to the same network.
• 🔄 Reboot your router: Sometimes this helps eliminate speed lags. Unplug the router for 30 seconds, then plug it back in.

⚠️ Attention: If your internet service provider (ISP) limits your data (for example, with a "10 GB per month" plan), downloading the firmware may exceed your limit. Check your ISP's plan details in your account.

3. Step-by-step instructions: updating via Wi-Fi

Once the network and device are ready, proceed with the update. Follow the instructions carefully—interrupting the process may result in a system crash.

1. Connect iPhone 5s to the charger (even if the charge is above 50%).
2. Open Settings → General → Software Update.
3. Wait for the system to check for updates. If a new version is available, click Download and install.
4. Agree to the terms of the license agreement (if required).
5. Enter the password from Apple ID (if requested).
6. Wait for the download to complete (this may take from 20 minutes to several hours depending on your internet speed).
7. After downloading, click Install now or Install tonight (if you want to postpone the process).
