An image posted on Reddit by user "Good-Breadfruit3577" has exposed the internal components of Samsung's upcoming Galaxy Z Fold 8 Ultra. The teardown reveals that the device, which is just 4.1mm thick when unfolded and priced at $2,099.99 for the base model, lacks a vapor chamber. Instead, Samsung has opted for a graphite sheet to cool the Snapdragon 8 Elite Gen 5 processor, raising concerns about thermal throttling under heavy workloads.

The lack of a vapor chamber may cause severe thermal throttling during intensive tasks.
