Part 1: Why are My TikTok videos lagging?

Lag is a common issue with TikTok, and several factors can cause it. Some of them are written below:

Out-Dated Device: When you're having difficulties playing videos on any platform, the first thing you should look at is your device. Using an outdated or low-end smartphone, the TikTok app may struggle to perform properly, resulting in video blurring and lagging.

Apps in Background: While using TikTok, you may have other applications running in the background, putting an additional burden on your device and causing it to overheat or collapse.

Unstable Internet: Another major cause of TikTok video buffering or lagging troubles might be an unstable Internet service. For the TikTok videos to operate, load, and play properly, you'll need a steady Internet connection with no significant downloads or background activities.

Part 2: Fixes TikTok Lagging Video Issues

Here are some ways you can follow to get rid of the TikTok Lagging Video Issue. Make sure to follow the instructions carefully.

1 Clear the Caches of the TikTok

Many users experience TikTok lag as a result of watching too many videos. As a result, TikTok accumulates additional caches on your mobile device. As a result, you must clear the cache for TikTok to work efficiently on your phone. To accomplish this:

  • Open the TikTok app and select the "Me" option. Then, go to your profile and click the three dots to access TikTok settings.
  • Select Clear Cache from the menu selections. Relaunch the TikTok app to see if this resolves the lagging issue.

    To upgrade TikTok on iOS, follow the steps below:

  • To begin, navigate to your device's App Store. And go to your profile and search for TikTok.
  • Finally, click the Update option to install the most recent version of the software.
  • update tiktok ios

  • Then click the Update icon next to TikTok to install the most recent version. And return to your profile after the update and check whether TikTok is still slow.

    3 Restarting iPhone

    If you are still facing the issue, your iPhone might still be experiencing a software issue. Minor software issues and malfunctions can be fixed by restarting your iPhone. Depending on the model of your iPhone, you can restart it in one of two ways:

    iPhone 8 and earlier: Hold down the power button until the words "slide to power off" display on the screen. To turn off your iPhone, swipe it from left to right. To restart your iPhone, press and hold the power button one more.

    iPhone X or later: Hold the volume and side buttons until "slide to power off" displays on the screen. Swipe the red and white power symbol from left to right to switch off your iPhone. To restart your iPhone, press and hold the power button.

    4 Connect with Well-condition Network

    A sluggish internet connection may also prevent your device from loading TikTok videos. To rule out this possibility, we recommend doing a speed test on any speed-checking website to determine your network's current capacity.

    If you are not receiving the speed specified on your subscription service, try restarting your network router or modem to reconnect to your ISP.

    After that, run another network test to see if the problem has been resolved. If not, contact your service provider and let them handle the matter.

    5 Force Stop the App

    TikTok uses memory and storage, so if your device doesn't have enough of either, it will overheat and become unresponsive. The videos on TikTok may therefore remain buffering or cease loading.

    To disable any background processes for the TikTok app in this situation, we advise you to force stop and close the application. Additionally, quickly restarting the software may fix any short-term problems while beginning a fresh experience on the platform. Here's how to do it.


  • Open the Application Manager on your device in iOS First.
  • The TikTok app may be found and moved up, down, right, or left to disappear from the app bar.
  • Android

  • Go to Settings > Application, and locate TikTok in the list of applications and choose it.
  • Click the Force Stop button present on the app's info page.
  • 6 Reboot Router/Modem

    The TikTok app may undoubtedly have a lot of lag difficulties due to a broken WIFI network. As a result, you must ensure the WIFI signal strength and speed are at their best.

    Unplug your modem's power cord from the main power source to accomplish this. Reconnect the power cord to the main power outlet once three minutes have passed. Connect your device to the Wi-Fi network after a little delay. You can see that your TikTok app is currently lag-free.
