iOS: Lag spikes (freezes) occur in all single and multiplayer modes (realms, private, public servers)

Major lag spikes happen with ~15-30 second intervals on iOS when connected to realm. The same bug does not occur on Xbox. No similar lag spikes on local world or public server (eg cubecraft). This bug makes it more or less impossible to play on realms at the moment and it has been affecting me since update 1.20.31

For the other players connected to the realm, whatever action I preform while the lag spikes takes place continues, it is purely on my end that it seems to lag. The screen freezes however the action continues, and it’s very disorienting when sprinting and suddenly everything stops for 1-2 seconds, only for my player to appear somewhere complete different to where I was when the lag spike initiated. As if a few frames were somehow lost on my end. And no, this is not because of my resource packs.

EDIT: Affects private worlds and public servers as well. Tried to uninstall the game and all resource packs but no difference. Audio also lags out a few seconds before or after lag spike.

Can confirm. Seriously annoying bug.

Appears to be triggered by changing perspective

I reproduced this also on singleplayer worlds, pretty much the same occurence as Android issue. Updating title.

I am experiencing this issue on an iPad Air M3 with the latest iPadOS and Minecraft version.

The game freezes for 2-5 seconds every few minutes during normal gameplay, even in new worlds with default settings and low render distance.

I have already tried lowering graphics settings, limiting FPS, disabling visual effects, and reinstalling the game, but the issue persists.

The device also heats up quickly during gameplay, while other games run smoothly without any issues.

This strongly suggests a Minecraft Bedrock optimization issue on M-series iPads.

I’ve found a reliable way to reproduce severe chunk freezing in Bedrock (with RenderDragon). Here’s a simple test...

All the stuttering and freezing during chunk generation are caused by RenderDragon. For example, when you set the render distance to 2 chunks and let the world generate for a while, the game starts to struggle noticeably. While it's struggling and chunks are still failing to load, try this: immediately open the settings and crank the render distance up to a high value. You’ll then witness what real chunk freezing looks like – the world will completely lock up, chunks stop rendering entirely, and block interactions become delayed or unresponsive.

All mobile devices, including the iPad, are impacted as well.

This issue still persists in version 26.51. While playing in‑world, intermittent stutters occur at regular intervals. The screen freezes completely and recovers after 1‑3 seconds.

Any iOS players here? Do you also get severe stutters or 0 FPS freezes when picking up items with Vibrant Visuals? If so, please reply.

Note:Testing this requires a high-precision FPS monitor; otherwise, these instantaneous frame drops cannot be detected.
