vivo X300 Pro

  • Blazing-fast 90W wired charging
  • Higher peak display brightness (2113 nits)
  • Potentially higher peak CPU performance with Dimensity 9500
  • Long battery lifespan with 1200 charge cycles

  • Less established software ecosystem
  • Camera performance is currently unknown

Samsung Galaxy S24 Ultra

  • Superior active use battery life (13:49h)
  • Refined software experience and ecosystem
  • Established camera prowess and video capabilities
  • Excellent thermal management with Snapdragon 8 Gen 3

  • Slower charging speeds (45W wired)
  • Lower peak display brightness (1447 nits)

Display Comparison

The vivo X300 Pro boasts a significantly brighter display, reaching a measured 2113 nits compared to the S24 Ultra’s 1447 nits. This translates to superior visibility in direct sunlight. While both likely employ LTPO technology for adaptive refresh rates, the X300 Pro’s peak brightness is a clear advantage for outdoor users. The S24 Ultra’s display is still excellent, but the X300 Pro takes the lead in sheer luminance. We expect both to have excellent color accuracy, but independent testing will be needed to confirm.

Camera Comparison

Samsung has historically excelled in camera performance, and the S24 Ultra is expected to continue this trend. While specific sensor details are missing for both, Samsung’s image processing algorithms are highly refined. The X300 Pro’s camera capabilities are less known, but vivo has been steadily improving its camera technology. Without detailed sensor information, it’s difficult to make a definitive judgment. We’ll need to analyze image samples to assess dynamic range, color accuracy, and low-light performance. The S24 Ultra’s video capabilities are likely to be superior, given Samsung’s expertise in this area.

Performance

The core of this comparison lies in the chipsets. The Mediatek Dimensity 9500 (3nm) in the X300 Pro features a unique core configuration – 1x4.21 GHz C1-Ultra, 3x3.5 GHz C1-Premium, and 4x2.7 GHz C1-Pro – suggesting a focus on sustained peak performance. The Snapdragon 8 Gen 3 (4nm) in the S24 Ultra, while clocked lower at 3.39GHz for its Cortex-X4 prime core, benefits from Qualcomm’s optimizations and a more mature software ecosystem. The 4nm process of the Snapdragon offers better thermal efficiency, potentially mitigating throttling during extended gaming sessions. The X300 Pro’s 3nm node *should* offer similar benefits, but real-world testing is crucial. Both phones utilize LPDDR5x RAM, ensuring ample memory bandwidth.

Battery Life

The Samsung Galaxy S24 Ultra edges out the vivo X300 Pro in active use battery life, achieving 13:49h compared to the X300 Pro’s 12:45h. However, the X300 Pro compensates with significantly faster charging – 90W wired, capable of replenishing the battery much quicker than the S24 Ultra’s 45W wired charging (65% in 30 minutes). The X300 Pro also offers 40W wireless and reverse wireless charging, while the S24 Ultra is limited to 15W wireless and 4.5W reverse wireless. The X300 Pro’s 1200 charge cycles suggest a focus on long-term battery health.

Buying Guide

Buy the vivo X300 Pro if you need the absolute fastest charging speeds available on a smartphone and are comfortable with a potentially less refined software experience. Its 90W wired and 40W wireless charging are unmatched. Buy the Samsung Galaxy S24 Ultra if you prefer a more mature ecosystem, a consistently excellent camera system, and a longer-lasting battery during typical daily use, even if it means slower charging.

Frequently Asked Questions

❓ Does the Dimensity 9500 in the vivo X300 Pro overheat during prolonged gaming sessions?
While the 3nm process should improve thermal efficiency, the Dimensity 9500’s aggressive core configuration could lead to heat generation under sustained load. Real-world testing is needed to determine if vivo’s cooling solution effectively mitigates throttling. The Snapdragon 8 Gen 3 in the S24 Ultra is known for its efficient thermal management.
❓ How much faster is the 90W charging on the vivo X300 Pro compared to the 45W charging on the Samsung Galaxy S24 Ultra?
The vivo X300 Pro’s 90W charging will significantly reduce charging times. While the S24 Ultra reaches 65% in 30 minutes, the X300 Pro is expected to fully charge much faster, potentially reaching 100% in under 40 minutes. This is a major advantage for users who frequently need to top up their battery quickly.
❓ Is the difference in display brightness between the two phones noticeable in everyday use?
The 666-nit difference in peak brightness is most noticeable outdoors in direct sunlight. The X300 Pro’s brighter display will remain more legible in these conditions. Indoors, the difference is less pronounced, but the X300 Pro still offers a more vibrant viewing experience.
