Refresh rate | 90 Hz, 120 Hz, 144 Hz | Purchase guide | The phone


Hey all, Welcome to Geeksforjobs

Refresh rate

introduction :

Does a high refresh rate really matter? What is the highest refresh rate for mobiles? What is the difference between 90hz and 120hz? How is it working? At what rate should we consider shopping?…

There are many questions that come up when we are willing to buy a new smartphone. And one of them is the refresh rate. Let’s know something interesting about it.

Fast launch:

The launch of the smartphone is faster than in the last few years. Brands like Realme are launching phones every month.

Innovation required:

And it is a needy to introduce some innovative stuff when comparing an older generation smartphone.


Upgrading from one to one quad-camera in the camera section is in trend nowadays. But when it comes to reality the secondary camera is just for making numbers. To attract buyers.

Google move:

Top brands like Google are still using the same camera in their phones. In their recent launch, they launched a phone called 4a with a single camera for the price of 30000.

It is quiet enough to survive against the quad-cameras of various brands in that price range when it comes to performing their singles.

You might wonder how is this possible using a single instead of a quad?

Software :

Because using the software, secondary lenses such as portrait shot, zoom and micro can also be done.

Google is working more on their software than using secondary lenses.

Fast Charging:

The other thing that comes to mind is fast charging and big battery. Fast charging can be a fancy thing when we buy.

But in the day-to-day life, there will be a tremendous reduction in the use of phone batteries.

Minimum monster:

Adding large batteries has been the useless thing when using these fast chargers.

And these heavy batteries will add more weight to the gadgets and are unfit to handle the task.

Selling Items:

They tried some innovations like big screen, add free UI, etc. and now they are starting to sell their devices at a refresh rate as a major selling point.

Before going into the depth of refresh rate, it is better to understand how the display works.

Refresh rate:

The basic explanation is about the performance of moving images or frames in consecutive time intervals.

When we are watching a film the frames move rapidly one by one which was a difficult task for the human brain to indicate the motion of the frame in several microseconds.

Refresh rate

Picture in every moment:

At a refresh rate of 60HZ, the frame began to refresh 60 times for one second. And it will gradually increase the refresh time per second according to the higher refresh rates.

When a user is changing their gadget from the normal 60 Hz to 120 Hz or 90 Hz, they may feel some smoothness when viewing images. This is due to the number of frame refreshes per second.


Gamers are beneficiaries when using this technique because these refresh rates are similar to graphic processor frame rates. They both depend on the number of frames per second.


The 60 Hz display takes 16.63microseconds and it only takes 8.33 microseconds to refresh the 120hz frame.

The user can experience a pleasant experience in games like Fortnite etc. while playing a huge FPS game at 120hz refresh rate.

Provides some smoothness in multitasking by providing quick responses in the daytime for high refresh rate usage. But we cannot see much difference in our regular basic functions.


Like the innovations mentioned above, there are some cons to consider when picking up the device in a high refresh rate.


The major one is that the higher frame rate per second the battery will have a higher percentage of drainage speed.

In general, phones with these innovations are purchased in a budget segment, which lasts for an average duration of only 3 years.

After that our gadgets will probably slow down. In that case pushing a higher frame rate will put some additional burden on the gadgets and may be likely to die.


We can expect higher refresh rates in laptops and tablets in the future…
