7 Solutions to Fix TikTok Lagging on Computer and Mobile

Part 1. Why Is TikTok Lagging So Much?

Before going right into how to stop lagging on TikTok, it is important first to understand the reasons behind it.

⭕ Common Scenarios:

• My TikTok is lagging upon scrolling: This happens when there's some delay in loading new content or the app won't act at a fast enough rate compared to your actions.

• My TikTok lags down while recording: The app may struggle to process the real-time video, therefore delaying recording.

• TikTok video lagging after posting: This sometimes happens when there is a delay in processing or uploading your video to the TikTok server.

⭕ Possible Reasons:

There could be a number of reasons why is my TikTok lagging. The most common ones include:

• Poor internet connection: If your Wi-Fi or cellular data is too weak or unstable, TikTok may not be able to load content or upload videos seamlessly.
• Performance of devices: Some older or low- performance devices just cannot keep up with the video-intensive content that TikTok serves up.
• Glitches or bugs in the application: Sometimes, the glitch or bug can be in the application itself, which is causing the lag, especially when it is outdated or not functioning properly.
• Too many apps running: Running too many apps in the background will consume your device's resources and make TikTok lag.
• Corrupted app data or cache: Accumulated cache and data can interfere with the app's performance and lead to lag.
• Outdated TikTok app: The older version of the app may contain bugs or compatibility issues that are causing lag.
• Background downloads or updates: The phone itself, or other apps running on your device, might be in between some background download or update process. It slows down the efficiency of the working of TikTok.
• Low storage space: When your device starts to run short on storage, it certainly hampers overall performance that will extend to TikTok, too.

Just disconnect your AirPods from your device by turn off the Bluetooth on mobile. Then try using TikTok without the AirPods and check if the sound syncs properly.

• Wait 30 seconds, then plug it in.

• Wait for the connection to stabilize and then open TikTok to see if it no longer lags.

By following these steps, you should notice your performance of TikTok has greatly improved. If it is still lagging, then you can contact the Helpline for TikTok for further assistance.
