Summary
- Vivo officially confirmed the X300 E launches July 27 in China; pre-orders are live now on vivo’s official online store.
- The 7,200mAh battery is the only spec vivo confirmed directly — beating our earlier leak estimate of 7,015–7,100mAh by a small margin.
- Official design reveal shows a square camera module with Zeiss-branded triple cameras including a periscope telephoto, available in black, orange, and white.
- Previous leaks point to a 6.59-inch AMOLED display, Snapdragon 8 Gen 5 chipset, 50MP main, 50MP periscope telephoto, 8MP ultrawide, 90W wired charging, and a 203g weight.
- This is the Snapdragon-powered alternative in the X300 lineup — sitting alongside the Dimensity-based X300s and above the camera-focused X300 FE.
The Battery Number Is Now Official
Leaks had the X300 E at 7,015–7,100mAh. Vivo’s own confirmation lands at 7,200mAh. That’s a meaningful correction upward — and it’s one of the largest batteries in any slim non-gaming flagship announced this month. The X300 FE, which launched globally and sits in a similar price corridor, carries 6,500mAh with 100W charging. The X300 E goes bigger on capacity, though the rumored 90W charging speed suggests a different trade-off: more battery, slightly slower fill rate.
At 203g and the dimensions implied by the 6.59-inch display, the X300 E isn’t a heavy phone. Fitting 7,200mAh into that chassis at a weight below the typical gaming phone puts it in interesting territory — closer to the Honor X80 Pro Max philosophy of big battery in a practical body, but with Zeiss camera credentials the Honor doesn’t carry.
Vivo confirmed 7,200mAh and a Zeiss periscope on the same teaser card — two specs that usually don’t coexist outside flagship Ultra territory. The X300 E is making a specific argument about what you actually need from a premium phone day-to-day.
Three Cameras, One Confirmed Partnership

The 8MP ultrawide is the one spec worth noting honestly. It’s functional, but it’s a step down from the 50MP ultrawide on the X300 Pro and X300 Ultra. If wide-angle photography is important to you, that gap matters.
