The vivo X300 has a substantially fuller published specification sheet, while OPPO’s announcement gives only a few Reno15 Pro Mini details. The available evidence does not establish a fair current price difference: vivo Austria announced a €1,049 launch recommended retail price in 2025, but OPPO has not published a Mini price in the cited announcement. Which is the better buy depends on your country and the exact local listings.

How the displays compare
vivo X300
vivo lists a 6.31-inch LTPO AMOLED screen with 2640 × 1216 resolution and an adaptive 1–120 Hz refresh rate. Those figures describe the global specification listing; the page does not establish an independent comparison of brightness, color accuracy, or viewing experience.
OPPO Reno15 Pro Mini
OPPO India describes a 6.32-inch AMOLED display with a minimum bezel width of 1.6 mm and a 93.35% screen-to-body ratio. It also names Corning Gorilla Glass 7i and AGC DT-STAR D+ glass. The announcement does not state the panel resolution or refresh rate, so the nearly identical diagonal alone cannot tell you which screen is sharper or smoother. These details are in OPPO India’s Reno15 Series announcement.
Performance, memory, and storage
vivo identifies the X300’s processor as MediaTek Dimensity 9500 and lists LPDDR5X Ultra RAM with 12 GB + 256 GB and 16 GB + 512 GB configurations globally. It also says ROM is not expandable. European storage options vary by country, so check the precise local model rather than assuming every listed configuration is sold in your market.

The cited OPPO announcement does not provide the Reno15 Pro Mini’s processor, memory, or storage configurations. OPPO Philippines has a specification page for a separately named Reno15 Pro 5G, model CPH2813, with a Dimensity 8450, but that page does not identify it as the Mini. Those specifications therefore cannot be used as Mini specifications without official confirmation (OPPO Philippines).
Battery and charging
vivo lists two X300 battery capacities by market: 6040 mAh for overseas markets except Europe, and 5360 mAh for Austria and Hungary. The same global specification page lists 90 W wired FlashCharge and 40 W wireless FlashCharge. These are manufacturer specifications, not measured battery-life results; capacity alone does not predict how long a phone lasts between charges. Check the listing for your country because the capacity differs by region (vivo).

The cited OPPO announcement does not provide the Reno15 Pro Mini’s battery capacity or charging rates. OPPO Philippines lists a 6200 mAh typical battery and 80 W SUPERVOOC for the Reno15 Pro 5G, but does not call that phone the Mini; those numbers should not be attributed to the Mini (OPPO Philippines).
Camera hardware
vivo’s European X300 overview describes a 200 MP ZEISS main camera, 50 MP ZEISS APO telephoto, and 50 MP ultra-wide camera (vivo Europe). These are hardware and branding specifications, not independent findings about photo quality. The cited OPPO Mini announcement does not list its camera hardware, so a meaningful camera-spec comparison is not possible from those details.

Build, protection, and software details
For the European X300, vivo lists IP68/IP69 protection and a weight of 190 g. Those figures are tied to the European model and should not automatically be applied to versions sold elsewhere. The global page lists Android 16; confirm the software version and update terms on the exact regional product page (European specifications; global specifications).
OPPO’s cited Mini announcement gives the display glass details but does not establish the Mini’s weight, ingress-protection rating, software version, warranty terms, or box contents. Do not infer those from the separately named Reno15 Pro 5G.

Price difference and availability
vivo X300 in Austria
vivo Austria announced a €1,049 recommended retail price for the X300. Its announcement, published 31 October 2025, said online-shop availability had begun on 30 October, with carrier, electronics-retailer, and online availability, including Amazon, from 3 November. This is a historical Austrian launch MSRP, not a current price or a price for other countries (vivo Austria, 2025).
OPPO Reno15 Pro Mini
OPPO India’s announcement names the Reno15 Pro Mini as the series’ first Pro Mini variant, but supplies neither a price nor a confirmed sale date in the cited announcement (OPPO India). As a result, a defensible price difference between the two phones cannot be calculated from the available official figures.
What to check before comparing local offers
- Confirm both listings are for the exact X300 and Reno15 Pro Mini models, not a similarly named Pro or Pro 5G variant.
- Compare the same country, currency, storage configuration, and seller type; check whether a displayed price is a current offer or a launch price.
- Check local stock, warranty coverage, network-band compatibility, and return terms for each exact SKU.
- Verify included charger and case contents with the regional listing or seller; the cited specifications do not settle these details.
Which phone should you choose?
The X300 is the more assessable option on published specifications: vivo provides processor, storage, display, charging, camera, and market-specific battery details, alongside European weight and protection information. That does not establish that it is better value at today’s price in your country, nor does it prove real-world camera or battery performance.
The Reno15 Pro Mini may suit someone seeking a compact-design variant, but the announcement’s 6.32-inch screen and bezel figures are not enough to judge its performance, cameras, battery, or value. Wait to compare it until OPPO or a reliable local listing confirms the Mini’s complete specifications and price. No independent named-person testing or study statistic is available in the cited material; manufacturer figures should be treated as specifications, not independent results.
