While nowadays smartphones are very powerful, they also come with a few drawbacks because of that, such as unimpressive battery life and high operating temperature. If companies want to have the chipset inside the phone working on its highest clocks, they need to use heat pipes.
We have now learned that future Samsung smartphones will not only have heat pipes in 2018, but Samsung is thinking of using vapor chambers in flagship phones in 2019. While heat pipes increase the price of the phone, vapor chambers are even more expensive and bulkier, which goes against the current trend of thin phones.
