Samsung has adopted a larger cooling solution on this year's Galaxy S23 series, but according to a rumor, the company is testing a "combined coil antenna" that the grapevine has rumored to be. Not only is this alternative said to be better than the copper sheets and heat pipes found in current generation smartphones, but it will also improve the reliability of features on some high-end models.

It should be noted that Samsung's adoption of a "combined coil antenna" will be costly and may force a series of Chinese manufacturers to abandon fast charging technology.
How to deal with such a compact space inside a smartphone body is a difficult challenge for several manufacturers, including Samsung. RGcloudS published a detailed article about the X, pointing out that current cooling solutions including copper sheets and heat pipes will affect connectivity features such as wireless charging, which also explains why only flagship models are equipped with these solutions.
The tipster also mentioned that the combined coil antenna is expensive, but if implemented correctly, it can make wireless connectivity more reliable than current models. The new solution extends not only to integrated wireless charging coils, but also to UWB, Bluetooth, 5G and Wi-Fi chips. However, besides cost, there are other disadvantages to using this solution.
If almost every smartphone comes with a coil combination antenna, manufacturers will no longer be able to implement fast charging on smartphones. However, the tipster did not mention that Chinese brands that tend to add 80W or higher power fast charging support are likely to find this technology cumbersome to use. Companies like Samsung and Apple, whose high-end phones charge no more than 45 watts, will find this alternative useful if cost is no object.
It's important to note, though, that companies like Samsung rigorously test their smartphones using various cooling solutions, so it wouldn't be surprising if the Galaxy S24 series insists on using heat pipes instead of combined coil antennas.
