vivo X300 Pro

  • Exceptional battery life (48:21h endurance)
  • Cutting-edge Dimensity 9500 chipset (3nm)
  • Higher peak display brightness (2113 nits)

  • Camera specifications unknown
  • Brand recognition may be lower than Xiaomi

Xiaomi 13 Ultra

  • Renowned camera system (Xiaomi Ultra series)
  • Mature software experience
  • Fast 90W wired charging (35 min to 100%)

  • Shorter battery life (10:09h active use)
  • Snapdragon 8 Gen 2 may throttle under sustained load

Display Comparison

Both devices feature high-end displays, but the vivo X300 Pro takes a slight lead with a measured peak brightness of 2113 nits, significantly exceeding the Xiaomi 13 Ultra’s 1207 nits. This translates to superior visibility in direct sunlight. While both likely employ LTPO technology for adaptive refresh rates (not specified in data), the X300 Pro’s higher brightness is a tangible benefit for outdoor users. The Xiaomi 13 Ultra’s display is still excellent, but the X300 Pro offers a more impactful visual experience.

Camera Comparison

The provided data highlights the Xiaomi 13 Ultra’s focus on camera capabilities, though specifics are limited. While the X300 Pro’s camera specs are absent, Xiaomi’s Ultra series is renowned for its advanced imaging systems. The 13 Ultra likely features a larger main sensor and more sophisticated image processing algorithms. However, without detailed specifications for the X300 Pro, a definitive camera comparison is impossible. It’s reasonable to assume the Xiaomi 13 Ultra holds an advantage in image quality and versatility, particularly in challenging lighting conditions, given its brand reputation.

Performance

The core difference lies in the chipsets. The vivo X300 Pro’s Mediatek Dimensity 9500, built on a 3nm process, promises superior efficiency and performance compared to the Xiaomi 13 Ultra’s 4nm Snapdragon 8 Gen 2. The Dimensity 9500’s octa-core configuration, with a peak clock speed of 4.21 GHz on the C1-Ultra core, suggests a focus on single-core performance, crucial for responsive UI and app loading. The Snapdragon 8 Gen 2, while powerful, may exhibit more thermal throttling under sustained load due to its larger process node. The X300 Pro’s architecture is designed for efficiency, potentially leading to cooler operation and longer peak performance durations.

Battery Life

The vivo X300 Pro demonstrates a clear advantage in battery endurance, achieving a remarkable 48:21h rating and a 12:45h active use score. This significantly surpasses the Xiaomi 13 Ultra’s active use score of 10:09h and older endurance rating of 108h. Both support 90W wired charging, with the Xiaomi 13 Ultra claiming a full charge in 35 minutes. The X300 Pro also offers 40W wireless and reverse wireless charging, while the 13 Ultra provides 50W wireless and 10W reverse wireless. The X300 Pro’s superior endurance, combined with competitive charging speeds, makes it the more practical choice for users who prioritize all-day battery life.

Buying Guide

Buy the vivo X300 Pro if you need maximum battery life, sustained gaming performance, and the latest chipset technology. It’s ideal for power users who demand all-day usability and aren’t heavily invested in a specific camera ecosystem. Buy the Xiaomi 13 Ultra if you prioritize a mature camera system with extensive features, and are willing to trade some battery life for a well-refined software experience and established brand reputation.

Frequently Asked Questions

❓ Will the Dimensity 9500 in the vivo X300 Pro overheat during extended gaming sessions?
The Dimensity 9500’s 3nm process node is designed for improved thermal efficiency compared to the Snapdragon 8 Gen 2’s 4nm node. This suggests the X300 Pro is less likely to experience significant throttling during prolonged gaming, potentially maintaining higher frame rates for longer periods. However, real-world performance will depend on the phone’s cooling system, which is not specified in the provided data.
❓ How does the 90W charging on both phones compare in real-world usage?
While both phones support 90W wired charging, the Xiaomi 13 Ultra claims a full charge in 35 minutes. The vivo X300 Pro’s charging time is not specified, but it’s likely comparable. The key difference lies in the X300 Pro’s 40W wireless charging, which is faster than the 13 Ultra’s 50W wireless, potentially offering quicker top-ups without a cable.
❓ Is the Xiaomi 13 Ultra's camera system worth the trade-off in battery life?
For photography enthusiasts, the Xiaomi 13 Ultra’s camera system is likely a compelling reason to choose it despite the shorter battery life. Xiaomi’s Ultra series consistently delivers exceptional image quality and versatility. However, if battery life is a primary concern, the vivo X300 Pro offers a significant advantage.
