Vivo has released the X300 Ultra flagship smartphone, which faces direct competition from the Samsung Galaxy S26 Ultra in thermal management and audio performance. Independent testing reveals that the Vivo device runs significantly warmer under load than its Samsung counterpart. The Galaxy S26 Ultra maintains cooler operating temperatures while delivering superior sound quality across the frequency spectrum.
Audio analysis highlights distinct weaknesses in the Vivo X300 Ultra speaker system.
Thermal testing shows the Vivo X300 Ultra reaches a peak temperature of nearly 55 degrees Celsius, or 131 degrees Fahrenheit. Despite the higher heat output, the Vivo device demonstrates better throttling control during sustained performance tasks compared to the Samsung model. This suggests the Vivo hardware manages long-term load efficiency more effectively, even at higher temperatures.
Audio analysis highlights distinct weaknesses in the Vivo X300 Ultra speaker system. The device exhibits greater fluctuations in its pink noise profile and performs poorly in both bass and super-tweeter ranges. In contrast, the Galaxy S26 Ultra provides a more balanced sound with audibly more pronounced bass and higher overall clarity.
Import pricing for the Vivo X300 Ultra starts at around 1100 $ (about $1,100). Analysts suggest that these hardware compromises may stem from an ongoing DRAM shortage, though this cause remains unconfirmed. The pricing places the device in the premium segment where thermal and audio distinctions become critical differentiators for consumers.
