1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsChoose the vivo X300 if you want the more compact phone: vivo lists it at 6.31 inches and 190g. Consider the OnePlus 15 if you prefer a larger display or put a larger listed battery capacity high on your checklist. Neither camera specifications nor battery capacity alone establish which phone takes better photos or lasts longer, and there is no country-specific price comparison here to declare a value winner.

Choose based on the phone you want to use
Pick the vivo X300 for a smaller footprint
The X300’s official dimensions—150.57 × 71.92 × 7.95mm and 190g—make its compact positioning concrete. If one-handed handling, pocketability or a smaller display matters more than screen size, this is the clearer fit on the available specifications. vivo Global specifications

Consider the OnePlus 15 if you want the larger-screen direction
OnePlus advertises a 165Hz display, while the secondary comparison describes the OnePlus 15 as having the larger screen. The retrieved official specifications do not provide extractable dimensions for a precise size or weight comparison, so do not infer a particular difference in hand feel from the refresh-rate figure. OnePlus product page; 91mobiles comparison
Camera specifications show different approaches, not a winner
The X300 pairs a high-resolution 200MP main camera with a 50MP telephoto and 50MP ultra-wide; vivo’s China page specifies 3× optical telephoto zoom. OnePlus lists a triple 50MP system with a periscope telephoto. The X300 also lists a 50MP front camera. vivo Global specifications; vivo China specifications; OnePlus product page

Megapixel counts and lens labels do not establish real-world image quality. There is no controlled head-to-head photo evidence here to determine which phone is better for portraits, night scenes, motion, video or zoom. If camera performance is your deciding factor, compare samples from the exact regional models and the kinds of shots you take rather than treating the spec sheet as a verdict.
Battery capacity is not battery life
OnePlus lists a 7,300mAh dual-cell battery. vivo lists a typical 6,040mAh capacity for overseas markets except Europe, and 5,360mAh typical in Austria and Hungary; it also lists 90W wired and up to 40W wireless charging. These figures describe listed capacity and charging support, not screen time or endurance. No comparable battery test was established, and OnePlus charging rates were not extractable from its official specification result. OnePlus US specifications; vivo Global specifications

Check the exact market version before buying
The vivo global page varies battery capacity by region and says the charger is included outside Europe but not in Europe. Network bands, eSIM availability and carrier behavior can also depend on country, carrier and software. An imported phone should not be assumed to have local warranty coverage or the same network support as a locally sold SKU. Confirm the exact model, supported bands, charger contents and warranty with the seller and your carrier. vivo Global specifications
Software listings are Android 16 with OriginOS 6 for vivo and Android 16 with OxygenOS 16 in OnePlus’s US specifications. The available information does not establish a software-update-duration comparison, and it does not resolve regional software differences. vivo Global specifications; OnePlus US specifications

Price and value depend on where you shop

These are China-market suggested prices, not verified live offers or international prices. vivo China specifications and suggested prices
Without your country, exact configurations and current local offers, a fair price comparison is not possible. Compare the same storage tier where available, and include warranty, seller legitimacy and network compatibility in the cost—not just the sticker price.

Verdict: make the choice around size, then verify the rest
The vivo X300 is the better-supported choice if you specifically want a smaller phone with published compact dimensions. The OnePlus 15 is the more obvious candidate if you want a larger display and its higher listed battery capacity appeals to you, but neither runtime nor overall value follows automatically from those specifications. For camera quality, protection equivalence or performance, the available evidence does not support naming a winner. Let local price, regional support and hands-on preference break the tie.
