The Samsung Galaxy S25 Edge, like other models in the S25 series, is expected to feature a variable refresh rate display, which can switch between different refresh rates depending on the content being displayed. This includes support for up to 120Hz, which offers smoother scrolling and animations compared to the standard 60Hz refresh rate. However, using a higher refresh rate like 120Hz generally results in increased power consumption compared to a lower refresh rate like 60Hz.
In similar Samsung models, such as the Galaxy S20 series, switching from 60Hz to 120Hz resulted in a noticeable decrease in battery life. For example, the Galaxy S20 Ultra experienced a drop of about 20% to 25% in battery life when using 120Hz instead of 60Hz[1]. Similarly, the Galaxy S20 Plus and the smaller Galaxy S20 saw even more significant reductions, with decreases of 33% and 36%, respectively[1].
For the Galaxy S25 Edge, which is rumored to have a smaller battery (around 3,900mAh to 4,000mAh) compared to some other models in the series, the impact of using 120Hz could be more pronounced due to the limited battery capacity[2]. The phone's enhanced power efficiency from the 3nm Snapdragon 8 Elite chipset might help mitigate some of this effect, but users can still expect a shorter battery life when using the higher refresh rate compared to 60Hz.
To maximize battery life on the Galaxy S25 Edge, users might consider reducing the refresh rate to 60Hz, especially if they are not frequently engaging in activities that benefit from higher refresh rates, such as gaming or fast scrolling. Additionally, other power-saving strategies like lowering screen brightness and limiting network usage can also help extend battery life[6].
