How to troubleshoot your iPhone X with slow browsing issue

Before you begin troubleshooting network problems on your iPhone X, try to reboot your wireless router/modem first. Doing so will ensure that the problem is not due to firmware crashes on the wireless router or modem — the main source of your Internet connection. If all your devices are experiencing the same issue with the Internet, then most likely the router or modem is to blame. As resolution, power cycle or reboot your wireless router/modem. To do so, toggle the Power button/switch to shut down the equipment. While it’s powered off, unplug the AC adapter from the power source and leave it unplugged for about 30 seconds to 1 minute. After the elapsed time, plug it back in then turn on again. Wait until the router/modem has booted up completely then restart your iPhone X. Connect to the Internet after the restart to see if the problem is fixed. If not, then go ahead and troubleshoot your device with these methods.

First solution: Clear cache, cookies, and history from Safari.

Cache or temporary files stored on the browser app can be the culprit when they crash or get corrupted. In this case, clearing cache files from the browser will likely fix the problem. If you are using Safari browser, you can clear history, cookies and cache using the Settings app. Doing so will help speed up browsing through the Safari app on your iPhone X. Here’s how to clear cache, cookies and history from the iPhone X Safari app:

  1. Tap Settings.
  2. Tap Safari.
  3. Tap Clear History and Website Data.

Your device then starts deleting browsing data from Safari. Your auto-fill information won’t be affected in the process, so they won’t be deleted.

If you want to clear cookies but keep your history, here’s what you should do then:

  1. Tap Settings.
  2. Tap Safari.
  3. Tap Advanced.
  4. Tap Website Data.
  5. Select the option to Remove All Website Data.

If you don’t want to leave a history when visiting websites through Safari app, then you can enable private browsing. You’ll know when there’s no history data to clear if the setting appears gray.

Second solution: Turn Wi-Fi off and on again.

This could be just a minor network glitch that can be resolved by restarting Wi-Fi connections on your iPhone X. The simplest trick you can try on is by turning Wi-Fi off and on shortly. This clears any random glitches transpiring on the Wi-Fi network and refreshes the Internet connection on your device. Here’s what you should do then:

  1. Tap Settings.
  2. Tap Wi-Fi.
  3. Tap the switch to turn off Wi-Fi. After a few seconds, tap the switch to turn Wi-Fi back on.

Try to connect and see if Internet browsing speed has improved. If not, then move on to the next method.

Third solution: Forget Wi-Fi network then reconnect.

It’s possible that the new update had caused wireless networks to destabilized or become corrupted. If that is the case, deleting the Wi-Fi network can fix it. When you delete or forget Wi-Fi network, it allows your device to connect to the wireless network as if it’s the first time it does. Before you do so, take note of your Wi-Fi password as it will be deleted in the process. Then proceed with these steps:

  1. Tap Settings from the Home screen.
  2. Tap Wi-Fi.
  3. Touch the blue “i” or information icon next to the Wi-Fi network you want to delete/forget.
  4. Tap the option to Forget this Network.

Reboot your iPhone X (soft reset) then scan and connect to your Wi-Fi network again with these steps:

  1. Tap Settings from the Home screen.
  2. Tap Wi-Fi.
  3. Tap the Wi-Fi switch or slider to turn on Wi-Fi, if necessary. Your iPhone will then scan for Wi-Fi networks in range.
  4. Scroll to and tap to select the Wi-Fi network you want to connect to.
  5. If prompted, enter the correct Wi-Fi network password.
  6. Tap Join.

Wait until your iPhone is connected to Wi-Fi. Once it says “Connected,” open the Safari browser app then do try to browse different sites to see if it’s already loading faster. Otherwise, continue to troubleshoot.

Fourth solution: Reset network settings on your iPhone X.

Performing a network settings reset can help if the problem has something to do with invalid network settings on your iPhone X. This will reset all data connections back to the original values or factory defaults. Wi-Fi networks are also cleared. If you wish to try it, then here’s how to reset network settings on your iPhone X:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Tap Reset.
  4. Select Reset Network Settings from the given options.
  5. If prompted, enter your device passcode to continue.
  6. Tap to confirm network settings reset.

Your iPhone then instigates the network settings reset and automatically restarts when done. After the reset, you will need to set up and connect to your Wi-Fi network to connect to the Internet again.

Fifth solution: Restore your iPhone X in iTunes.

If none of the prior methods helped and you still end up having the same slow browsing issue on your iPhone X, then performing an iOS restore can be considered as your last resort. To get started, connect your iPhone to your computer using the supplied Lightning cable. Launch iTunes on your computer. Then force restart your iPhone X with these steps:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. Finally, press and hold the Side/Power button until the Recovery Mode (Connect to iTunes) screen appears. Don’t release the buttons when the Apple logo appears as you need to enter recovery mode.
  4. If prompted with the option to Restore or Update iPhone, select Restore to wipe out all existing data from your device and install the latest iOS version.
  5. If you select Update, your device will upgrade the software to the latest version while keeping all contents and settings of your iPhone. Let iTunes download the software for your device.
  6. If the download takes more than 15 minutes, your iPhone exits recovery mode. In this case, just let the download to finish and then go back to the previous steps to enter recovery mode again.
  7. Once the Update or Restore is complete, proceed with the initial device setup. Follow the onscreen instructions to complete the setup process.
