The Indian smartphone landscape just received a seismic shock: vivo has officially launched the vivo X300 Pro and vivo X300, two devices engineered to pull the rug from under every so-called “flagship killer” and declare quite confidently that the flagship throne now belongs to them.

With batteries large enough to power weekend vacations, camera systems that can threaten cinema cameras, and displays bright enough to blind your enemies, the new X300 series is positioned as the boldest, most unapologetically futuristic lineup vivo has ever shipped to India.

Moment of Truth

vivo X300 Series starts at ₹75,999 and the X300 Pro comes in at ₹1,09,999.

Pre-booking is live today, sales start 10th December 2025.

A Revolution Wrapped in Armor: Design & Build Quality

Both the vivo X300 Pro and vivo X300 come dressed like they’re ready for a mission on Mars. Each features a glass front with Armor/Reinforced Glass protection, an aluminum alloy frame, and a glass back polished with vivo’s trademark elegance.

• IP68/IP69 certification makes them tougher than half the “rugged” phones pretending to survive the monsoon.
• Survive high-pressure water jets? Check.
• Survive accidental dips? Check.
• Survive your clumsiness? Mostly… yes.

X300 Pro: 161.2 x 75.5 x 8 mm, 226g
X300: 150.6 x 71.9 x 8 mm, 190g

The Pro feels like a powerhouse, while the smaller X300 feels like a flagship that went to the gym, got lean, and still punches above its weight.

A Display That Doesn’t Just Shine. It Screams.

LTPO AMOLED with 4500 Nits Peak Brightness Daylight Has Competition

Both phones come with bezels so thin even minimalists would approve.

  6.78-inch LTPO AMOLED, 120Hz, 2160Hz PWM, HDR10+, HDR Vivid, Dolby Vision
  Resolution: 1260 x 2800, 452 ppi
  Peak brightness: 4500 nits (realistically, enough to replace a flashlight)

  Resolution: 1216 x 2640, 460 ppi

Performance That Redefines “Overkill”: Dimensity 9500

Powered by the MediaTek Dimensity 9500 (3 nm) chipset, these devices aren’t just fast they are scientifically engineered to embarrass other flagships struggling with “thermal issues.”

CPU Architecture

• 1× C1-Ultra at 4.21GHz
• 3× C1-Premium at 3.5GHz
• 4× C1-Pro at 2.7GHz

One core for heavy lifting. Three for sustained performance. Four for multitasking. Zero chance of lag.

GPU: Arm G1-Ultra

High-end gaming? Shoot at 8K? Run AI tasks faster than your laptop? Yes, yes, and yes.

The benchmark numbers scream flagship supremacy:

• X300 Pro:
  AnTuTu v11: 3,533,222, Geekbench 6: 10,264, 3DMark: 7263
• X300:
  AnTuTu v11: 3,416,530, Geekbench 6: 9,843, 3DMark: 7510

Essentially: Flagships of 2024 are now officially in their retirement era.

Battery: The New King of Endurance
