Samsung preps new smartphone cooling tech using combo coil antenna

Published

on

Galaxy S22 Vapor Chamber Cooling

Samsung is reportedly considering adopting combo coil antenna cooling technology. With this year’s Galaxy S23 series, the company introduced bigger cooling solutions. However, the new rumored solution is said to be better than copper plates and vapor chambers as well as improve the reliability of features.

According to RGcloudS, current cooling solutions that include copper plates and vapor chambers can affect connectivity features such as wireless charging. If the expensive combo coil antenna is implemented properly, they could make wireless connectivity features more reliable.

The combo coil antenna doesn’t only expand to the integrated wireless charging coils but can also be expanded to the UWB, Bluetooth, 5G, and Wi-Fi chips. However, phone makers won’t be able to implement fast charging (80W+) if nearly every model ships with coil combo antenna.

Since the technology is still under development, we might not see it commercialized quite soon. Since Samsung tests out Galaxy flagships rigorously with various cooling solutions, the Galaxy S24 series could still ship with vapor chamber cooling rather than combo coil antenna technology.

MediaTek could help Samsung keep on evolving as Snapdragon price soars

Samsung Galaxy S24 Ultra One UI 7 Beta

Samsung is unlikely to use Exynos 2500 in the Galaxy S25 series. Qualcomm has increased the prices of the Snapdragon 8 Elite due to upgrades. However, MediaTek could help Samsung keep on evolving flagships as Snapdragon price soars.

Recently, it was reported that the Snapdragon 8 Elite 2 could be pricier than the Snapdragon 8 Elite. Samsung Foundry is in trouble and there’s no hope for Exynos 2600 to be used in 2026’s Galaxy S26 flagship smartphones.

Chipset price makes a great impact on smartphone pricing. Samsung managed to freeze pricing by utilizing Exynos in previous flagships. However, the game has changed as consumers don’t want Exynos and Snapdragon continues to be pricier.

Korean media (via Jukanlosreve) believes that MediaTek could help Samsung flagships keep on evolving further amid pricier Snapdragon. If Snapdragon 8 Elite 2 is to be exclusively used in the S26 series, we may not see any display and camera upgrades.

Chinese phone makers aggressively utilize the Dimensity chips, that decently rival the latest Snapdragon chipset. Exynos is uncertain but MediaTek is doing a pretty good job with its flagship Dimensity chips.

In the case of no Exynos, opting for Dimensity in the Galaxy S series is a better alternative. MediaTek’s prices are way too lesser than Qualcomm’s. Meanwhile, flagship Dimensity chips offer better performance than Samsung’s Exynos.

Samsung skipped upgrading the display and zoom camera on the S25 Ultra, as far as the rumors are concerned. It could be forced to replace the same pursuit on the Galaxy S26 series otherwise, the price freeze would be unavoidable.

Samsung Galaxy S25 Ultra Dummy

Global Samsung Galaxy S25, S25 Plus, and S25 Ultra surfaced on the FCC database. Earlier, we’ve seen the appearance of the US variants of the S25 series. The listing reveals the model number, connectivity specs, and some more info.

FCC listed Global Samsung Galaxy S25, S25 Plus, and S25 Ultra as model numbers SM-S931B, SM-S936B, and SM-S938B, respectively. The variants will be launched outside the US such as Asia, Africa, Europe, Latin America, and the Middle East.

The input solidifies that the vanilla S25 won’t feature UWB tech. The fast and secure connectivity feature will be limited to the Galaxy S25 Plus and S25 Ultra. The US variants listing revealed the UWB configuration on the upcoming flagships.

Supporting documents suggest that the S25 and S25+ were tested with the EP-TA800 charging adaptor and EP-DN980 cable. Support for Bluetooth 5.4, Wi-Fi (802.11 b/g/n/a/ac/ax/be), GNSS, DP, and NFC are also mentioned.

The Galaxy S25 Ultra is also listed with S Pen support. It will be the only model in the lineup that will be supporting stylus input. As far as the charging speed is concerned, the S25 Plus and S25 Ultra will bring 45W fast charging support.

The flagship will also feature Bluetooth 5.4, Wi-Fi (802.11 b/g/n/a/ac/ax/be), GNSS, UWB, DP, and NFC connectivity. The supported 5G bands include n1/2/3/5/7/8/12/20/25/26/28/38/40/41/66/77/78.

Galaxy S25 Ultra Release Date

Samsung hasn’t yet officially announced the release date for the Galaxy S25 series. South Korea is currently facing political tension as the President has recently imposed Martial Law (Emergency) and lifted it shortly after.

Korean media previously reported that the Galaxy Unpacked may be held in late January next year. If things continue to go as planned, we can expect the S25 series to be unveiled on January 22, while release could happen in early February.

Samsung Galaxy S25 Plus reappears with Exynos 2500 chipset

Samsung Galaxy S25+

Samsung has just tested Exynos 2500 chipset on the Galaxy S25 Plus. Samsung’s unannounced SM-S936B was spotted on Geekbench 6. However, the retail model could be equipped with Snapdragon 8 Elite globally.

As spotted by Jukanlosreve, the Samsung Galaxy S25 Plus running Exynos 2500 scored up to 2358 and 8211 points in single-core and multi-core tests. The model number refers to the European variant of the Galaxy S25 Plus smartphone.

In early November, the chipset was spotted on the same handset with similar Geekbench scores. That time, the Exynos 2500 reached 2,359 points and 8,141 points in Geekbench 6’s single-core and multi-core CPU tests.

The current Exynos 2500 benchmark scores are far from its rivals. The Snapdragon 8 Elite manages to reach up to 3127 and 9509, while Dimensity 9400 reaches 2711 and 8632 points in single and multi-core tests, respectively.

It is said that the Exynos 2500 may not power the Galaxy S25 series. The Korean tech giant has reportedly commenced mass production. The next year’s Galaxy Z Flip 7 could be equipped with a 3nm-based Exynos 2500 processor.

Geekbench reveals that the Exynos 2500 features a 10-core CPU, with the prime CPU core clocked at 3.3GHz, two high-performance cores at 2.75GHz, and three at 2.36GHz. The platform has two power-efficient CPU cores, running at 1.8GHz.

Samsung’s in-house chip is speculated to get Xclipse 950 GPU based on AMD’s RDNA architecture. It could also be supported by Vulkan 1.3, additional dynamic state, device profiles, dynamic rendering, and improved sync API.

The Foundry division is currently facing yield issues with the 3nm process. Industry observers estimate that the yield rate is extremely low (around 20%). Given the yield concerns, Exynos 2500 is unlikely in the Galaxy S25 series next year.
