What cooling tech does the Galaxy Z Fold 8 Ultra use?

Samsung, during the Galaxy Z Fold 8 Ultra‘s launch event and in its promotional material, highlighted the upgrades the device brings over the Galaxy Z Fold 7, but it didn't talk about every aspect of the phone.

That has left enthusiasts with many unanswered questions, including whether the brand's latest book-style foldable features a vapor chamber for cooling. If you've been looking for the answer, you've come to the right place.

No, the Galaxy Z Fold 8 Ultra does not feature a vapor chamber for cooling. Samsung used a vapor chamber in previous Fold models up to the Galaxy Z Fold 6, but switched to graphite sheets with the Galaxy Z Fold 7, most likely to make the device thinner.

The Galaxy Z Fold 8 Ultra continues to use the same graphite-based cooling solution.

While a vapor chamber would have been a welcome addition, the Galaxy Z Fold 7 didn't suffer from any major thermal management issues despite relying on graphite sheets instead. Similarly, in our review of the Galaxy Z Fold 8, which uses the graphite-based cooling solution, we found that the device didn't heat up much even during demanding tasks such as gaming.

The Galaxy Z Fold 8 Ultra runs similarly cool when running demanding tasks. And while the Snapdragon 8 Elite Gen 5 throttles during long gaming sessions, it's pretty standard behavior for such a powerful flagship chip, especially in an ultra-thin device.
