Smartphones today are not just a device for calling; they pack the power of a mini-computer in our pockets. As apps become larger, processors become faster, and graphics evolve many folds, there’s a heavy load on devices. This excessive load results in even the best phones heating up. If you’re a PUBG fanatic or binge watch Netflix, you know how important a fast smartphone is that doesn’t crack under pressure. This is where the Liquid Cooling Technology in the top phones comes to your rescue.

What is Liquid Cooling?

Liquid Cooling works on the principle of dissipation of heat. A heat pipe is installed in the device, which contains a cooling liquid. Upon excessive heat generation, this pipe absorbs the heat from the chip-set and turns the liquid into vapour. This condensation of the liquid dissipates the heat and cools down the ambient temperature.

Which liquids are used?

Water, de-ionized water, glycol-water solutions, fluorocarbons are some of the commonly used fluids for cooling. Most top smartphones use water, but in a minimal quantity that essentially always stays in the vapour form, thus resulting in the popular name – ‘vapour cooled system’. Nokia and Samsung were the first two brands to adopt this technology. Today, all the best smartphones in the market use this cooling technique.

What about other cooling technologies?

Apart from liquid cooling, top smartphones make use of other technologies to keep the device cool. A popular one is the traditional ‘air cooling’ which uses fans to dissipate the heat and cool down the chip-set. Another such technology is ‘throttling’ i.e., restricting the power of the device before it hits its maximum, to moderate the temperature rise.

What lies in the future?

Look out for the liquid cooling technology when you compare smartphones before making a purchase, especially if you are a heavy user and frequently juggle between apps. Many of the top phones of 2019 are equipped with this technology, but due to lack of awareness in terms of utility, it is still not a priority feature for smartphone buyers. There is also the fact that with each new update, smartphone manufacturers are making processors and batteries more energy-efficient. A huge emphasis is put on prevention of heating of the device, compared to after-cooling measures.

A smartphone tip here would be to check the device specifications, as per your usage, before making a purchase. Compare mobiles and go for the one that guarantees heat resistance. You don’t want your device to heat up like an iron rod, each time you stream online.
