The short version
- Korea's Seoul Economic Daily reports that Samsung's tests found the Snapdragon 8 Elite Extreme Gen 6 repeatedly going past its temperature limits in the Galaxy S27 Ultra.
- Under long, heavy loads, the chip reportedly slowed itself down to cool off.
- Samsung reportedly asked Qualcomm for a fix by mid-October. If it doesn't land, the backup is Samsung's own Exynos 2700.
- This is unconfirmed. It comes from unnamed industry sources, and neither company has commented. There's no India price or launch date for the S27 series yet.
What the report says
The Snapdragon 8 Elite Extreme Gen 6 is Qualcomm's top phone chip this year. Qualcomm says it's the first phone chip to hit 5 GHz. Our Gen 6 vs Extreme Gen 6 explainer covers how it differs from the standard version.
According to the report, Samsung's internal checks found it kept crossing its heat thresholds. When that happens, a chip lowers its clock speed to protect itself. That's called thermal throttling, and our throttling explainer breaks down how it works.
Samsung reportedly sent its results to Qualcomm in September, and both are still retesting.
The Exynos backup
The Exynos 2700 is built on Samsung's second-generation 2nm process, called SF2P. The report claims it beats the Snapdragon in parts of Samsung's testing.
That would be a big change. Samsung last put Exynos in an Ultra with the Galaxy S22 Ultra in Europe. Since then, every Ultra has used Snapdragon worldwide. Right now, Exynos only appears in the standard Galaxy S26 and S26+ in Korea.
How much to trust it
Seoul Economic Daily is an established Korean business paper. But the report names no sources, gives no temperatures, and doesn't say which countries would get Exynos.
On paper, a chip running hot in early testing isn't unusual. Final hardware and software tuning often changes the picture. Mass production of the S27 series is reportedly set for late 2026.
What to watch: whether Qualcomm's fix lands, and which chip the Indian Galaxy S27 Ultra ends up using.
