Design and Display: Compact Comfort vs Big-Screen Power
The Vivo X300 FE comparison with the iQOO 15 and Xiaomi 17 is about finding a compact premium phone that balances size, performance, and flagship phone value for demanding users. Vivo’s 6.31-inch LTPO AMOLED panel and compact glass–metal body make it easier to use one-handed than the larger 6.85-inch iQOO 15. Both Vivo and iQOO offer IP68/IP69 durability, but Xiaomi’s similar-sized Xiaomi 17 only has IP68, trading extreme ruggedness for a slightly richer multimedia setup with Dolby Vision. Vivo’s 5000-nit peak brightness beats Xiaomi’s 3500 nits, giving the X300 FE better outdoor visibility. However, Xiaomi counters with Dragon Crystal Glass and higher Mohs level protection, while iQOO pushes immersion with a bigger, sharper 144Hz screen. In short, Vivo emphasizes comfortable size and visibility, iQOO focuses on sheer screen impact, and Xiaomi splits the difference with protection and Dolby Vision flair.

Performance and Daily Experience: Snapdragon Showdown
On paper, the iQOO 15 and Xiaomi 17 hold the edge with Snapdragon 8 Elite Gen 5 chips and Adreno 840 GPUs, while the Vivo X300 FE runs the standard Snapdragon 8 Gen 5 with Adreno 829. This gives iQOO and Xiaomi more headroom for high-frame-rate gaming and heavy multitasking, aided by memory options up to 16GB RAM and 1TB storage. Vivo counters with a more balanced, thermally aware approach. According to Gizmochina, the X300 FE includes bypass charging support, which helps keep temperatures lower during long gaming sessions. All three promise Android 16 support, but Vivo explicitly commits to five major updates, offering a clear path for long-term use. In real-world terms, iQOO and Xiaomi target power users who chase maximum benchmarks, while Vivo aims at smooth, cool, and consistent performance in a smaller body.
Camera Systems: Zoom Power vs Ultrawide Strength
Vivo leans hard into photography, especially zoom and portraits. Its 50MP main camera with Zeiss optics and 50MP periscope lens focus on refined tuning and polished zoom output, beating the iQOO 15’s comparable hardware through better image processing and Zeiss collaboration. The X300 FE also records 8K and 4K at up to 120fps, outclassing iQOO’s 4K 60fps ceiling. Against Xiaomi 17, Vivo trades blows. Xiaomi offers a more balanced triple 50MP array, with sharper ultrawide shots and stronger creator tools such as 8K HDR, Dolby Vision, and LOG recording. Both Vivo and Xiaomi share 50MP autofocus selfie cameras, but Xiaomi adds HDR10+ for enhanced selfie video. In contrast, Vivo’s 8MP ultrawide is a weak point, especially beside iQOO’s and Xiaomi’s 50MP ultrawide hardware. For zoom and portraits, Vivo shines; for wide landscapes and pro video, Xiaomi takes the lead.
Battery, Charging, and Connectivity: Endurance Trade-offs
All three flagships offer large batteries and fast charging, but the priorities differ. The Vivo X300 FE packs a 6500mAh battery with 90W wired and 40W wireless charging, while the iQOO 15 increases capacity to 7000mAh and nudges wired charging to 100W alongside the same 40W wireless rate. Xiaomi 17 lists 6330mAh globally and up to 7000mAh in its China variant, paired with 100W wired and faster 50W wireless charging. Vivo’s advantage lies in practicality: its compact size plus 6500mAh capacity offer strong endurance without the bulk of iQOO’s larger frame. Connectivity also diverges. iQOO uses newer Bluetooth 6.0 and Wi-Fi 7, while Xiaomi’s USB Type‑C 3.2 with DisplayPort suits users who need desktop-style setups. Vivo keeps things simpler with dependable standards and bypass charging, prioritizing stability and comfort over headline-grabbing speeds.
Value and Who Should Buy Which Phone
When you compare prices, patterns emerge. The Vivo X300 FE is priced around ₹80,000, the iQOO 15 around ₹73,000, and the Xiaomi 17 around ₹90,000. Vivo positions itself as a balanced compact premium phone, offering Zeiss-tuned cameras, strong brightness, IP68/IP69 durability, and clear long-term software support at a middle-ground price. iQOO undercuts it with better raw performance, larger battery, and sharper ultrawide camera, making it ideal for gamers and spec hunters willing to live with a bigger device. Xiaomi 17 targets users who want the “maximum hardware” experience: faster chip, richer multimedia with Dolby Vision and Atmos, stronger screen protection, and advanced video tools. Yet its higher price means the overall flagship phone value tilts toward Vivo. The X300 FE punches above its expected positioning by pairing compact ergonomics with high-end cameras and dependable updates, making it a smart default choice for most buyers.
