How to Monitor CPU, Memory, and Device Health on iPhone

TL;DR

CleanMaster's System Info dashboard shows live CPU, memory, and per-core load charts, plus your device profile — model, core count, uptime, and thermal state — so you can see what your iPhone is actually doing.

Steps

Open CleanMaster and go to the System Info dashboard.
Watch the live CPU and memory load charts, including per-core usage.
Check your device profile — model, core count, uptime, thermal state.
Note the thermal state if your phone feels hot under load.

Why it works this way

iOS hides most of what your phone is doing, so a sluggish or hot device leaves you guessing. CleanMaster surfaces the live vitals — CPU, per-core load, memory, and thermal state — in clear charts, so you can tell whether something is genuinely hammering the system. It reads local stats only, with nothing sent off-device.

Tips & edge cases

Watch the thermal state when the phone gets warm — it explains throttling.
Per-core charts show whether load is spread or pinned to one core.
Pair with the widgets for an at-a-glance read without opening the app.

FAQ

What can I monitor? Live CPU (overall and per-core) and memory load, plus device details like model, core count, uptime, and thermal state.

Are the charts real-time? Yes. The load charts update live, powered by Swift Charts.

Does monitoring need an account or network? No. It reads local device stats — no account, no upload.
