Xiaomi HyperOS 3.1 solves that annoying boot-up lag

We’ve all been there: you restart your phone, unlock it, and then… wait. For the first minute or two, the interface stutters, widgets struggle to load, and tapping an app feels sluggish. With the release of Xiaomi HyperOS 3.1, Xiaomi is tackling this “cold boot” sluggishness head-on with a clever underlying optimization.

The new update introduces a system-level feature that pre-compiles applications before the boot process completes. Instead of the system trying to compile app data while you are actively trying to use the phone (which causes the lag), HyperOS 3.1 handles this heavy lifting during the boot sequence itself.

TL;DR

• The Fix: HyperOS 3.1 now pre-compiles apps during the boot animation.
• The Result: Drastically reduced UI stutter and lag immediately after unlocking.
• Visual Indicator: You may see a “Optimizing apps” progress bar (as seen in the leaked image) during updates or restarts.

How It Works: “Optimizing Apps” Returns

If you’ve been using Android for a long time, the screenshot above might look familiar. In earlier versions of Android, we used to see an “Optimizing Apps” screen after every system update. Xiaomi seems to be bringing a smarter, faster version of this concept back to ensure stability.

By shifting the compilation process to the boot stage, the CPU can dedicate full power to preparing your apps without fighting for resources against the launcher or your touch inputs.

The result? When your lock screen finally appears, the phone is actually ready to use. The system feels fluid instantly, rather than needing that awkward “warm-up” period.
