vivo X300 E Launches With a 7,200mAh Battery and Zeiss Periscope

Vivo launched the X300 E in China on July 27, 2026, starting at CNY 4,799 (roughly $708) for 12GB of RAM and 256GB of storage, with sales opening July 31. It runs a Snapdragon 8 Gen 5, packs a 7,200mAh battery into a body under 8mm thick, and carries a Zeiss-tuned triple camera with a 50MP periscope telephoto.

That battery figure is the one that stopped me. A 7,200mAh cell in a 6.59-inch phone that weighs about 200 grams is not normal, and it tells you exactly where the Chinese flagship market has gone while Western phones have been arguing about thinness.

The battery is the story

Vivo calls it a “Blue Ocean” battery, using silicon-carbon chemistry to cram more capacity into the same physical space than conventional lithium-ion allows. The practical result is 7,200mAh in a phone measuring 7.79mm to 7.99mm thick depending on which color you pick, weighing between 199.5g and 203g.

For comparison, most flagship phones sold in the US this year sit somewhere between 3,500mAh and 5,000mAh. The X300 E has roughly half again more capacity than the top end of that range, in a chassis that is not meaningfully thicker or heavier. Charging is 90W wired, plus reverse OTG charging so the phone can top up your earbuds.

If you have ever nursed a phone through an afternoon at 12%, you understand why this matters more than another half-point of benchmark score. Our guide to making your phone battery last longer exists precisely because most phones do not have enough capacity to begin with.

Full specifications

The camera setup is lopsided on purpose

Look closely at the three lenses and you will notice something unusual: 50MP main, 50MP periscope telephoto, and then an 8MP ultra-wide. That last number looks like a mistake next to the other two.

It is a deliberate choice. Vivo put its money into the telephoto — a periscope design co-engineered with Zeiss, supported by dedicated modes including Telephoto Stage for shooting concerts and events in bad light, and Telephoto Landscape for compressed scenery shots. The ultra-wide is there because a phone at this price has to have one, not because Vivo expects you to live in it.

I would rather see this than four mediocre cameras. Most people shoot at 1x and occasionally zoom; almost nobody produces good work at 0.6x. Spending the sensor budget where the pictures actually get taken is the correct call, even if it makes the spec sheet look uneven.

The display does something specific with all those nits

A 5,000-nit peak brightness figure gets quoted a lot without much explanation, so here is what it means in practice. That number is a peak measured on a small portion of the screen, typically while displaying HDR content, not a level the whole panel sustains. You will never sit in a dark room at 5,000 nits — it would be painful.

Where it matters is direct sunlight. A panel with that much headroom can push a small bright region hard enough to stay readable at noon outdoors, which is the single most common situation where phone screens fail. Combined with a 144Hz refresh rate on a 1.5K AMOLED, this is a display specced for people who use their phone outside, not for spec-sheet bragging.

The rest of the hardware follows the same pattern of picking real-world wins: an ultrasonic fingerprint sensor rather than an optical one, which reads through wet or greasy fingers where optical readers fail, and Wi-Fi 7 support. OriginOS 6 handles software duties, which is Vivo’s own Android skin and the piece most likely to divide opinion outside China.

What “E” means and why you probably cannot buy one

The X300 E slots in beneath the X300 and X300 Pro as a more attainable entry to Vivo’s flagship camera line. It keeps the current-generation Snapdragon and the Zeiss partnership while trimming elsewhere — the 8MP ultra-wide is part of that trimming.

The bigger caveat is availability. This is a China launch. Vivo does sell the X300 series in Europe and parts of Asia, but the E variants historically stay domestic or arrive much later under different names, and Vivo has no meaningful US presence at all. Treat CNY 4,799 as a reference point for what roughly $700 buys in the world’s most competitive phone market rather than a price you can pay.

That comparison is the useful part. For about the same money as a mid-tier Western flagship, the Chinese market gets a current flagship chip, a 144Hz 5,000-nit panel, IP69, Wi-Fi 7, an ultrasonic fingerprint reader, and a 7,200mAh battery.

Frequently asked questions

How much does the vivo X300 E cost?

CNY 4,799 for the 12GB + 256GB model and CNY 5,299 for 12GB + 512GB, which converts to roughly $708 and $782. Those are Chinese launch prices; any international pricing, if it happens, will be higher after taxes and import costs.

When does the vivo X300 E go on sale?

Sales open July 31, 2026 in China, four days after the July 27 announcement. Vivo has not announced international availability, and the E variants of the X-series often stay in the domestic market.

How big is the vivo X300 E battery?

7,200mAh, using silicon-carbon “Blue Ocean” chemistry that fits more capacity into less space than standard lithium-ion. It charges at 90W wired and supports OTG reverse charging for accessories. The phone still measures under 8mm thick and weighs about 200 grams.

Does the vivo X300 E have a Zeiss camera?

Yes. The triple rear array — 50MP main, 50MP periscope telephoto, 8MP ultra-wide — is co-engineered with Zeiss and includes Telephoto Stage and Telephoto Landscape shooting modes. The specs were confirmed in Vivo’s own pre-launch material ahead of the announcement.

Is the vivo X300 E waterproof?

It carries both IP68 and IP69 ratings. IP68 covers immersion in fresh water; IP69 additionally covers high-pressure, high-temperature water jets, which is a step above what most phones claim. In practice it means rain, spills, and a dropped-in-the-sink accident are all survivable.
