Vivo’s getting ready to level up its top-tier lineup once more – the next X300 Ultra seems like a real game changer. Not just because the Ultra range usually nails photography, but ’cause this version keeps that fire alive. The standout here? A much bigger battery, paired with solid internal tweaks under the hood.

Vivo X300 Ultra Launching Details
A massive 7,000mAh battery may power the X300 Ultra.
A well-known Weibo poster suggests the Vivo X300 Ultra might pack a massive 7,000 mAh battery. That’d be the most significant seen so far in the X Ultra series. Earlier, the X200 Ultra came with a 6,000 mAh battery. Models like the X300 and X300 Pro offered 6,040 mAh or 6,510 mAh instead. Should this rumor hold up, Vivo’s likely crafting a device built to last way longer than most rivals.

A camera system made for top-quality photos
Some early info shows a three-camera setup made for people who love taking photos. Word is there’ll be a 200 MP primary shooter, alongside a 200 MP zoom lens using periscope tech. Then you’ve got a 50 MP wide-angle option thrown in. The primary sensor could come from Sony, maybe the IMX09E model. As for the telephoto piece, it may run on Samsung’s HPB Thanos chip – the same one seen before in the Vivo X300 and Vivo X300 Pro. The ultra-wide camera might use Sony’s IMX09A sensor. While Zeiss likely sticks with Vivo, that partnership could keep photo quality solid on every lens.
Strong performance with Snapdragon 8 Elite Gen 5
Some new X300 phones in India might pack MediaTek’s Dimensity 9500, though the X300 Ultra could go another way. Instead of that chip, it’s likely to use the Snapdragon 8 Elite Gen 5 – so speed-wise, it’d pull ahead. That move would make the Ultra stand out as the top-tier pick across the lineup.
Expected launch timeline
Folks are saying the Vivo X300 Ultra might pop up early next year, by March. Some think it’ll hit China first, probably in April. If things go well overseas, folks in India could grab one soon afterward.
Final thoughts
If those first leaks are accurate, the Vivo X300 Ultra might be their best high-end phone yet. Thanks to a massive battery, its camera setup packs a serious punch – while a premium processor adds muscle under the hood. This combo could push Vivo’s top phones into fresh territory.
