Vivo X300e specs leak via China Telecom listing: Snapdragon 8 Gen5, 7200mAh battery, and camera details

A mysterious new entrant in the Vivo X-series has emerged: the Vivo X300e. The company has officially begun teasing the X300e in China (pre-orders opened July 20), but its full specification list only surfaced via a China Telecom certification site just before launch. This leak confirms the phone’s core hardware: a flagship Snapdragon 8 Gen5 chipset, a massive 7200 mAh battery, and a triple-camera system with dual 50 MP sensors. These specs fill in many blanks about the X300e that were previously just leaks. In this report, we break down every confirmed detail, separate it from speculation, and compare the X300e’s features with the existing Vivo X300 and X300 Pro models.

Key Highlights

• China Telecom listing reveals full spec sheet for Vivo X300e (model V2612A), ahead of its July 27 China launch.
• Confirmed features: 6.59″ 1.5K AMOLED display, Snapdragon 8 Gen5 SoC, 7200 mAh battery (90W charging), and ZEISS-tuned triple rear cameras (50MP primary + 50MP telephoto + 8MP ultra-wide).
• Software: Ships with Android 16 (OriginOS 6) and up to 12GB+512GB memory.
• Design: Unique square camera island (unlike X300/X300 Pro circle), available in black, white, and orange.
• Key differences: Vastly larger battery than X300/X300 Pro; uses Snapdragon instead of Dimensity; introduces ZEISS telephoto optics.
• Market positioning: Bridges the gap between compact mid-flagships and premium models, targeting gamers and content creators needing long battery life and high zoom camera.
• What’s next: Vivo’s official specs and pricing will be confirmed at the July 27 sale event, but this leak already gives buyers confidence about the phone’s high-end credentials.

Confirmed vs. Rumored Details

Every confirmed detail above is sourced from either the China Telecom listing or Vivo’s own pre-order page. Unverified items are clearly labeled as rumors or expectations.

Vivo X300e vs. X300 and X300 Pro

The table below compares the leaked X300e specs with Vivo’s existing X300 lineup:

Sources: Vivo official specs for X300 and X300 Pro; China Telecom listing and Vivo pre-order for X300e. The X300 series’ specs (e.g. battery and camera) were confirmed by Vivo’s official site and promotional materials.

Why the X300e Leak Matters

This leak is significant for several reasons:

• Battery record: A 7200 mAh battery in a ~200g phone is exceptional. It surpasses the X300’s 6040 mAh and X300 Pro’s 6510 mAh, potentially giving multi-day usage.
• Flagship power: Vivo skipped its usual Dimensity chipset and equipped the X300e with Qualcomm’s 8 Gen 5, bringing flagship-level performance to a device with mid-range positioning.
• Camera focus: The addition of a ZEISS-tuned periscope telephoto (50 MP) suggests Vivo is targeting mobile photography enthusiasts who want long-range zoom, a feature uncommon in non-premium models.
• Market strategy: By introducing an “E” variant with these specs, Vivo fills a niche between the compact X300 FE and the more expensive X300 Pro. This could pressure competitors to boost battery life and camera features in affordable flagships.
• Consumer transparency: Leaks like this let buyers confirm rumors ahead of launch. For example, potential customers now know the X300e will have 5G and a huge battery, not just look at renders.
• Technology trends: The leak highlights that big batteries (7K+ mAh) and 120Hz OLEDs are trickling down to non-flagship tiers, reflecting ongoing trends in the smartphone industry.

Key Takeaways

• The China Telecom listing effectively confirms most of the Vivo X300e’s hardware specifications. This includes flagship-grade internals like the Snapdragon 8 Gen 5 and an unusually large 7200 mAh battery.
• Vivo’s naming (“X300e”) and design (square camera bump) signal a new sub-model in the X300 series, positioned between the standard and Pro models.
• Compared to the X300/X300 Pro, the X300e trades a smaller Dimensity chip for a slightly slower Snapdragon, but gains significantly in battery capacity and adds a periscope zoom lens. This makes it stand out for power users and mobile photographers.
• The leak demystifies speculations: we now know it has 90W charging, 8/12 GB RAM options, a 1.5K display, and full 5G connectivity. Everything seems in line with a high-end mid-tier phone.
• Bottom line: The Vivo X300e leak indicates an intriguing new phone that promises extreme battery life and flagship performance. The confirmed specs suggest it could be a compelling choice for users who want top-tier features without paying Pro-level prices. We expect official confirmation (and pricing) at the July 27 launch event.

FAQs

1. What is the Vivo X300e and why is it important?
The Vivo X300e is a new addition to Vivo’s flagship X-series, launching in China in late July 2026. It’s important because leaks show it combines a Snapdragon 8 Gen5 processor with a massive 7200 mAh battery and ZEISS-tuned cameras. This positions it uniquely between the smaller X300 FE and the high-end X300 Pro.

2. Are the leaked specs confirmed?
Yes, the China Telecom listing provides official confirmation of almost all key specs: 6.59″ AMOLED, SD 8 Gen5, 7200 mAh battery, triple rear cameras (50+50+8MP), 90W charging, etc. These details match multiple sources. Anything not on the listing (like final price or global name) remains unconfirmed.

3. How does the X300e differ from the Vivo X300 and X300 Pro?
Compared to X300/X300 Pro, the X300e uses a Qualcomm Snapdragon chipset instead of MediaTek Dimensity. Its battery (7200 mAh) is much larger, but the X300 Pro has a 200 MP main camera whereas the X300e uses two 50 MP sensors plus an 8 MP ultra-wide. The X300e also features a unique square camera design and comes in bright orange color option.

4. What is the launch date and price of the X300e?
Vivo has set the Chinese sale date for July 27, 2026 (9:00 AM). Pricing isn’t announced yet, but leaks suggest it will be cheaper than the X300 Pro (CNY 5599+) and more than the X300 FE, possibly around the high-midrange segment. Official price will be revealed by Vivo on launch day.

5. Does the X300e support 5G networks?
Yes. Despite the name, the listing is on the China Telecom (5G) site, and all sources indicate the X300e is a 5G-capable smartphone.

6. Are these specs final, or could Vivo change them?
China Telecom approval suggests these specs are finalized. Once a phone is listed, manufacturers rarely change core hardware. However, software (HyperOS branding, apps) and local variations could still differ when sold outside China.

7. Will the X300e come to other markets (India/Global)?
No official word yet. Some analysts speculate a similar model (perhaps called X300t) might launch elsewhere, but there’s no confirmation. The focus of leaked info so far is on China.

8. Is there anything missing in the leak?
The listing doesn’t detail screen refresh rate (though it’s likely 120Hz) or camera apertures. It also doesn’t explicitly mention fast charging wattage (though Vivo’s pre-order page does). Otherwise, it provides a nearly complete spec sheet before launch.
