Vivo just gave its X300 series a fifth member, and this one breaks from the family’s usual design template. The X300 E went official in China today, July 27, arriving with a 7,200mAh battery that’s actually larger than what’s inside the standard X300, and a boxy camera module that looks nothing like the circular islands on the X300 and X300 Pro.
That battery number is the standout spec. Vivo’s China-market X300 ships with 6,040mAh, so the X300 E jumps past its own flagship sibling by more than 1,000mAh while still keeping the body at 7.79mm thick for the Orange and Black colorways thin enough that you wouldn’t guess there’s a battery this size crammed inside. Vivo is calling it the “Blue Ocean” battery, built on fourth-gen silicon anode tech, and pairing it with 90W wired charging.
Camera
Where the X300 and X300 Pro chase headline megapixel counts with a 200MP Zeiss main sensor, the X300 E dials that back to a 50MP Zeiss-branded Sony IMX921 primary camera, joined by a 50MP Sony IMX882 periscope telephoto with 100x zoom and an 8MP ultrawide. The front camera also gets a 50MP sensor with autofocus, which is a notable step up from the fixed-focus selfie cameras still common at this price tier. Vivo’s Zeiss partnership extends beyond hardware here too, with film-style color profiles and a custom color-grading tool called “Blueprint palette” built into the camera app.
Under the hood, the X300 E runs Qualcomm’s Snapdragon 8 Gen 5, a chip Vivo says delivers a 36% CPU gain and 46% NPU improvement over the Snapdragon 8 Gen 3 worth noting since the standard X300 actually runs MediaTek’s Dimensity 9500 rather than a Snapdragon chip, making the E model something of an outlier in how it’s positioned inside the lineup. RAM tops out at 12GB with virtual expansion pushing that to 24GB, paired with UFS 4.1 storage.
The display is a 6.59-inch 1.5K panel hitting 144Hz, 5,000-nit peak brightness, and 100% P3 coverage, alongside IP68/IP69 water and dust resistance and an ultrasonic fingerprint sensor rated for wet-finger unlocking. Vivo also kept the IR blaster, a feature increasingly rare on flagship phones outside China, along with full NFC support for transit and payment cards.
Vivo hasn’t announced pricing yet, and there’s no word on whether the X300 E will leave China the way the X300 and X300 Pro eventually did in Europe. Given this model swaps out the marquee 200MP camera for a bigger battery and a Snapdragon chip instead of MediaTek, it reads less like a scaled-down flagship and more like Vivo testing a different set of priorities endurance and everyday performance over camera bragging rights.
