Does Refresh Rate Affect Battery Life?
A 120Hz screen feels smooth from the first swipe.
At the same time, battery percentage drops quicker.
This makes many users confused.
Is refresh rate the real reason?
Short Answer
Yes, refresh rate changes battery life.
Also, higher refresh rates use more power.
So, battery size and screen control matter.
What Is Refresh Rate?
Refresh rate shows how many times the screen updates each second.
In simple terms, a higher number means smoother motion.
For example, 120Hz looks smoother than 60Hz.
Why Higher Refresh Rates Use More Battery
In simple terms, the screen refreshes more times each second.
As a result, the processor sends more frames.
At the same time, the GPU stays active.
So, battery drain increases.
