A smartphone is more than just a powerful processor, even though we enjoy comparing the Qualcomm Snapdragon and Apple A-series processors. The use of heat dissipation and cooling mechanisms is crucial for regulating a smartphone’s temperature and controls how often it throttles. Many smartphones crash when under a severe load, and they often disable their prime cores after a string of demanding tasks. Following our approach below will let you test smartphone throttling and determine the durability of your smartphone.
Test Smartphone Throttling (2021)
There are typically two simple methods for testing smartphone throttling. On Android devices, you can evaluate your CPU performance over time and how it controls cooling using a dedicated app called CPU Throttling Test. The AnTuTu benchmark app is also available for both Android and iOS devices, and it provides you with a good summary of throttling after a number of continuous tests. Since we went over both approaches in great depth, let’s start with the CPU Throttling Test.
CPU Throttling Test on Smartphone
Install the CPU Throttling Test app on your smartphone right away (it’s free). Open the app after that. Remember that the app suggests leaving the phone in a chilly state, so wait 10 minutes before performing any intensive tasks on the phone. Simply tap Start Test after that.
The graph above provides you with a thorough analysis of your smartphone’s performance over time. The general rule is that if your smartphone can withstand stress and effort over time, performance will be linear—that is, the line won’t decrease. If the performance line starts to drop, your smartphone has begun to throttle and will slow down to release heat. Sometimes it can even completely shut down the prime cores. You can notice in the image below that my OnePlus 7T’s performance remained linear even six minutes into the test.
After 11 minutes of testing, there was no discernible decline in performance, and the CPU could manage nearly 20 threads of demanding activity. For your knowledge, if the app displays the graph in yellow, it has begun to throttle, and when it turns red, it has nearly disabled all of the cores on your phone to lower its temperature.
The workload was immediately stopped by the app in my tests after 15 minutes, but the smartphone shown no signs of throttling. In order to spice things up, I upped the thread count to 40 from the Options menu and immediately relaunched the test. I performed this to test the CPU’s endurance performance while the temperature of the smartphone had not dropped to a normal level.
And this time, I did notice deeper dips in the graph, which shows that the CPU throttled a little bit after raising the thread count and beginning the test at a higher temperature. It goes on to demonstrate that every smartphone throttles, regardless of whether there has flagship specs or not, even though it wasn’t a significant dip. Furthermore, the significance of cooling and heat dissipation in the realm of smartphones cannot be overstated.
AnTuTu Smartphone Throttling
AnTuTu is well-known for being a benchmarking tool, but it may also shed a lot of light on smartphone throttling. AnTuTu may be downloaded from its official website for both Android and iOS. Open it following that. It will download a few plugins during the initial run in order to complete the labor-intensive test.
Simply hit Start once everything has been configured. It will start stressing your smartphone’s CPU and GPU to see how well it performs overall. You are probably going to finish the first test quickly, and you’ll probably obtain the highest grade. The same thing happened with my OnePlus 7T, which scored approximately 459337. The result for my second test was also roughly 459310.
The score began to drop, though, after many tests in which the phone was still hotter. I eventually discovered that the OnePlus 7T was slow and unable to handle the burden on my fifth test. It received a 395721 on the fifth test. It goes on to demonstrate once more that smartphones often throttle their CPU and GPU after repeated workloads in order to maintain the ambient temperature. But it’s great to know that flagship chipsets have grown to be fairly powerful and can withstand numerous torture tests without tiring.
Stress Test CPU and GPU of Smartphones
These are the two simple methods for stress testing your smartphone’s CPU and GPU. Every smartphone throttles, as I indicated before, but the question is how long a smartphone can handle the workload while keeping the temperature constant before throttling the CPU.
It is evident from my testing that premium smartphones can admirably sustain numerous rounds of intense workload. That’s all we have to say, though.
