Samsung has incorporated bigger cooling solutions on this year’s Galaxy S23 series, but according to one rumor, the company is testing what one tipster calls a ‘combo coil antenna.’ Not only is this alternative said to be better than copper plates and vapor chambers present in current-generation smartphones, but it can also improve the reliability of features of some premium models.
Unsurprisingly, adopting ‘combo coil antennas’ for Samsung will be costly and might force Chinese manufacturers to forego fast-charging
Dealing with a compact space such as the inside of a smartphone chassis is a daunting challenge for several manufacturers, including Samsung. RGcloudS has published a detailed post on X, stating that current cooling solutions that include copper plates and vapor chambers can affect connectivity features such as wireless charging, which would explain why only flagship models ship with them.
The tipster also mentions that the combo coil antennas are expensive, but if implemented properly, they could make wireless connectivity features more reliable than they are in current models. The new solution does not only expand to the integrated wireless charging coils but can also be expanded to the UWB, Bluetooth, 5G, and Wi-Fi chips. However, there are other drawbacks to using this solution aside from cost.

Manufacturers can no longer implement fast-charging on their smartphones if nearly every model ships with coil combo antennas. However, the tipster does not mention that Chinese brands who have a propensity of adding 80W of fast charging support and higher will likely find this technology cumbersome to use. Companies like Samsung and Apple, who do not go beyond the 45W charge limit on their premium handsets, will find this alternative useful, assuming that the cost does not get in the way.
However, do note that companies like Samsung test out their smartphones rigorously with various cooling solutions, so it should not be surprising if it sticks to vapor chambers for the Galaxy S24 family instead of combo coil antennas.
