Introduction
When it comes to mobile devices, the phrase "knowledge is power" takes on a whole new meaning. Today, we're delving into the world of CPU frequency monitoring – a key tool for identifying a common phenomenon known as throttling.
What is throttling
Before we can discuss how to identify throttling, we must first understand what it is. Throttling is a process where a device intentionally reduces its performance in order to control heat generation, conserve battery, or manage the device's lifespan.
In other words, when your phone or tablet starts to get hot from running too many apps or stays on for prolonged periods, it can automatically slow down the CPU to cool off. This process can lead to noticeable lags or stutters in your device's performance, and this is where monitoring CPU frequency becomes beneficial.
Throttling and frequency
Monitoring your mobile device's CPU frequency can give you insight into whether your device is being throttled or not. An irregular CPU frequency, with constant peaks and troughs, can indicate that your device is consistently throttling performance to manage heat or power consumption.
Now, let's explore how you can keep track of your device's CPU frequency and identify potential throttling.
Identifying Throttling Through CPU Frequency Monitoring
Step 1: Choose a CPU Monitoring App
Your first step is to download a CPU monitoring app from the Google Play Store like CPU/GPU Meter & Notification. You can not only monitor the frequency when the app is active but rather you can have all information in a system notification accessible in a single swipe (soon as a floating window too).
Step 2: Analyze the Frequency
Monitor the CPU frequency while running different apps or tasks on your device directly from the notification without leaving your app! If you device can reach manufacturer specified frequency then it is not throttled.
Usually every device is design to keep high frequency for a few seconds (typically completely enough to finish a task) and then they throttle. It is not design flow or something unexpected. This is just how a mobile device operate.
From Monitoring to Action: What to Do if Your Device is Throttling?
On one hand, throttling is normal process and there is nothing to worry about. It happens on every device under heavier operating conditions. On the other hand - if you device has recently started to throttle more than before it could mean that it is time to check it cooling system. Maybe the thermal connection between the CPU and radiator (a small metal piece inside the device or device's case itself) is not transferring the heat so well which leads to high temperatures forcing the device to throttle more and more.
Conclusion
Throttling is a normal process that helps manage your device's performance and lifespan. However, if it becomes too frequent, it can interfere with your everyday use. Monitoring your CPU frequency provides a window into your device's performance, helping you identify throttling and take corrective actions.
