Don't buy your smartphones based on YouTube speed tests

Smartphones have reached incredible heights in terms of processing power and memory management. One of the popular tests (apart from benchmark tests) is the speed test that a lot of people look in to before buying a smartphone. People compare phones based on a series of apps installed in the two or more devices. They open it up in a particular order and the phone that manages to open it faster is simply the one that performs better.

Although it says something about the device, it is not judgmental to the performance of the given device. Whenever an app is open, the app is first copied from flash drive to physical memory of the phone. This is the only thing that happens when you turn on an app. What you compare at this point is the speed at which the apps are copied from flash drive to the physical memory of the device and NOT the speed of the processor.

A lot of people have a misconception regarding how app load time is related to the processing power of the device. If you want a real comparison, try running the same game on both the devices in the same room. Make sure that graphics setting of the game remains the same for both the device. The type and specifications of display used will also play a critical role in the functioning. Measure the FPS of the game, this could be a much better performance test than simply opening and closing apps.

It is possible that smartphones with the same or lower load time in their flash drive could principally perform better during extended gaming sessions once the app is loaded to the memory. This means that we cannot trust these tests as a way to characterize the phone's performance.

The joke about memory/resource management.

Often times in the same test, some YouTubers just try to reopen the apps from memory. Yes, memory management is an essential thing in the performance of the device, but does this really test the memory management function?

Whenever the physical memory gets dumped by a lot of apps, some apps that were loaded in the ram could be erased in order to make space for the new apps. This is what exactly called memory management, but based on popular conception, this is a negative trade and the phone lacks memory management if it was unable to open up the app.

Which app system decides to erase is totally out of our control. So if in one phone the PUBGM was still in memory while on the other it didn't, it does not necessarily mean the RAM management of the second phone is bad. It is the random choice of the system to choose what apps to erase. If it wasn't PUBGM, it would erase 3 other apps to make room. So the idea that reloading apps from memory and comparing it would give one or two meaning about RAM management is awfully blatant.

What about real life conditions?

Normally when I use my phone, I do not open all my 100 apps, I just open one, spend some time with it, then move to the next app, spend some time and so on and so forth. This process kind of really tests the performance of the device. When I do run apps for a while, it would demand some work from the CPU and GPU. After sometimes, things could heat up and performance could be drastically affected.

The fact that these do not emulate the real-life condition of phone usage should be taken into account before you make choice on your device.


Don't let the numbers tell you what the performance of the device is going to be. If you really want accurate reviews of a device, try watching channels that publish day to day usage videos (Like GeekyRanjith) or ask a friend who used it. Online tests could be terribly cheating unless you know what you are seeing. Happy purchasing.
