The OPPO K13x 5G and vivo X300 FE are in very different price and performance tiers, so they are not close substitutes. The K13x is the budget choice, with a larger 6.67-inch screen and a 6,000 mAh battery; the X300 FE is the compact premium option, with a higher-resolution AMOLED display, Snapdragon 8 Gen 5, and a three-camera system that includes 3x optical telephoto. OPPO’s K13x prices below are its June 2025 launch prices, not current quotes. A third-party comparison page accessed October 4, 2026, displayed the K13x at ₹15,999 and out of stock, and the X300 FE at ₹94,999—a ₹79,000 difference between those displayed prices, not a verified current market gap.

Price difference: what the listed figures actually mean
OPPO announced the K13x in India on June 23, 2025, at ₹11,999 for 4/128 GB, ₹12,999 for 6/128 GB, and ₹14,999 for 8/128 GB. OPPO also announced launch-day offers that could reduce the effective price for eligible buyers. Those figures describe the launch, not what a retailer charges now. OPPO India’s announcement

The 91mobiles comparison page accessed October 4, 2026, showed ₹15,999 for the K13x and marked it “Out of Stock”; it showed ₹94,999 for the X300 FE with an Amazon reference. Subtracting those two page displays gives ₹79,000, but that arithmetic is not a reliable current-price comparison: one listing is out of stock, and the page’s price, variant, and availability can change. 91mobiles

Before buying, compare the same storage configuration and check the exact seller’s live stock, final checkout price, bank offers, and exchange terms. The comparison page’s displayed X300 FE storage configuration also differs from the options on vivo India’s parameter page, so confirm the India SKU rather than assuming variants are interchangeable.
Display: bigger viewing area or sharper AMOLED
OPPO K13x: larger LCD
The K13x has a 6.67-inch HD+ LCD with a listed 120 Hz refresh rate. Its larger screen gives more viewing area, which may suit readers who prefer a big display for everyday browsing and video. It is not the higher-resolution or AMOLED option in this comparison.

vivo X300 FE: smaller, higher-resolution AMOLED
The X300 FE’s 6.31-inch AMOLED panel is listed at 1216 × 2640 and 120 Hz. It is the more compact phone and offers the higher-resolution display technology on paper. Choose between the two based on whether screen size and budget matter more to you than compactness and panel specification; these figures alone do not establish a real-world brightness or image-quality result.
Performance: different hardware tiers
The K13x uses MediaTek’s Dimensity 6300, while vivo specifies Qualcomm’s Snapdragon 8 Gen 5 for the X300 FE. That is a substantial difference in processor tier and makes the vivo the more compelling choice for buyers seeking premium-class processing capacity. No independent, method-matched head-to-head benchmark result is established here, so a specific performance multiplier or guaranteed gaming outcome would be unjustified. Software, cooling, and the task itself also affect actual use.

Cameras: basic rear setup versus optical telephoto
K13x: main camera and depth sensor
OPPO lists a 50 MP main rear camera, a 2 MP depth camera, and an 8 MP front camera. The specification sheet does not give it a dedicated optical telephoto or ultra-wide camera.
X300 FE: three rear cameras and autofocus selfie camera
vivo lists a 50 MP main camera with optical image stabilization (OIS), a 50 MP 3x telephoto camera with OIS, and an 8 MP ultra-wide. Its 50 MP autofocus front camera is also a higher-resolution setup on paper than the K13x’s 8 MP front camera. The extra focal-length options make the X300 FE’s camera hardware more flexible, particularly for zoom and wider framing; megapixel counts and lens lists do not prove comparative photo quality.
Rank #4
- Magnetic Phone Case Compatible with Oppo K12s / K13 / K13x
- 【Built-in Magnetic Sheet for Secure Snap-On Charging】Embedded magnetic ring aligns perfectly with magnetic wireless chargers and car mounts—stays firmly attached, no slipping or frequent adjustments
- 【PU Leather Texture + Soft TPU Bumper】Elegant leather-like back offers a comfortable, anti-slip grip and refined look, while the flexible TPU edges absorb shocks and make installation effortless without scratching your device
- 【Raised Camera & Screen Protection】Reinforced raised bezels around the camera lenses and screen keep them lifted off flat surfaces, guarding against daily scratches, dust, and minor bumps. Precision cutouts preserve full button and port access
- 【Slim, Lightweight & Drop-Resistant】Streamlined profile stays pocket-friendly; four-corner cushioning and full-edge TPU frame help buffer everyday drops and bumps
vivo also promotes the optional ZEISS Telephoto Extender Gen 2, described as a 200 mm-equivalent external telephoto accessory weighing 153 g. Check regional availability, compatibility, price, and whether it is sold separately before treating it as part of the phone’s value. vivo X300 FE overview

The listed battery capacities are 6,000 mAh for the K13x and 6,500 mAh typical for the X300 FE; vivo gives the latter’s minimum rated capacity as 6,350 mAh. Capacity alone cannot tell you which phone lasts longer in comparable use. OPPO’s June 2025 announcement claims up to 19.3 hours of video playback, 40.7 hours of music, 56.8 hours of calling, and 10.6 hours of gaming for the K13x, but it does not specify test conditions in that announcement. These are manufacturer claims, not independently comparable battery test results. OPPO India

OPPO lists 45W SUPERVOOC wired charging for the K13x. vivo lists up to 90W wired charging with its original charger and cable, with power varying dynamically according to use conditions, and advertises 40W wireless FlashCharge for the X300 FE. The charging figures are maximum stated capabilities, not a promise of a fixed charging time. vivo India specifications
OPPO says the K13x has IP65 protection and is supplied with an Anti-Drop Shield Case. It also states that battery health remains above 80% after 1,700 charge cycles; the cited announcement does not include an independent test report for that claim. vivo lists IP68 and IP69 for the X300 FE, but its water-resistance qualification matters: IP68 testing is specified as static fresh water up to 1.5 metres for up to 30 minutes, and vivo warns resistance is not permanent and can lessen with daily wear. Neither rating makes a phone damage-proof. OPPO India · vivo India
Which phone should you choose?
Choose the OPPO K13x if
- Your purchase budget is the priority and you can find the model in stock at an acceptable current price.
- You want a larger 6.67-inch display and are comfortable with an HD+ LCD.
- You mainly need everyday phone use and do not require a dedicated optical telephoto or ultra-wide rear camera.
Choose the vivo X300 FE if
- You are prepared to spend substantially more for a compact premium handset.
- You value a higher-resolution AMOLED screen and Snapdragon 8 Gen 5 platform.
- You want optical 3x telephoto, an ultra-wide camera, a higher-resolution autofocus selfie camera, or wireless charging.
Neither choice is universally better: the K13x is the budget-oriented option, while the X300 FE offers a more premium feature set. Make the decision using verified live India prices and the exact storage variants available to you.
