The vivo X300 FE has the more advanced listed hardware, including a sharper AMOLED display, a higher-tier processor and a dedicated telephoto camera. The vivo Y21 5G has a larger but lower-resolution LCD and supports expandable storage. Both India-specification pages list a 6,500 mAh typical battery. A current price difference cannot be stated without matching variants and prices from the same country and seller.
At a glance: vivo X300 FE vs vivo Y21 5G
This comparison uses vivo’s India specification pages, so configurations may differ in other markets. The figures below are manufacturer-listed specifications, not results from independent testing.
| Feature | vivo X300 FE | vivo Y21 5G |
|---|---|---|
| Display | 6.31-inch AMOLED; 2640 × 1216; 120 Hz | 6.74-inch LCD; 1600 × 720; up to 120 Hz |
| Processor | Snapdragon 8 Gen 5 | Dimensity 6300 |
| Memory and storage | LPDDR5X Ultra; UFS 4.1; listed configurations include 8GB+256GB and 12GB+512GB; no expandable ROM | LPDDR4X; UFS 2.2; listed configurations pair 4GB, 6GB or 8GB RAM with 128GB storage; supports expandable storage up to 2TB |
| Rear cameras | 50MP main with OIS, 50MP telephoto with OIS and 8MP wide camera | 50MP rear camera and 0.08MP auxiliary camera |
| Front camera | Not stated on the cited specification page | 5MP |
| Typical battery capacity | 6,500 mAh | 6,500 mAh |

Which phone has the better display?
The X300 FE has the smaller screen but substantially higher listed resolution: its 6.31-inch AMOLED panel is 2640 × 1216, with a 120 Hz refresh rate. The Y21 5G’s 6.74-inch LCD is 1600 × 720 and supports up to 120 Hz. That makes the choice a compact, higher-resolution display versus a larger, lower-resolution one. A shared maximum refresh-rate figure does not make the panels otherwise equivalent.

How different are the performance and storage specifications?
The X300 FE lists a Snapdragon 8 Gen 5 processor, LPDDR5X Ultra memory and UFS 4.1 storage. The Y21 5G lists a Dimensity 6300, LPDDR4X memory and UFS 2.2 storage. Those are clearly different hardware tiers on paper; the listed components alone do not establish real-world speed or benchmark results.
Storage flexibility is a separate advantage for the Y21 5G: its India page lists 128GB storage configurations with 4GB, 6GB or 8GB RAM and support for expandable storage up to 2TB. The X300 FE page lists 8GB+256GB and 12GB+512GB configurations, with no expandable ROM. Confirm the exact RAM and storage combination offered in your market before buying.
What do the camera specifications show?
The X300 FE has three listed rear cameras: a 50MP main camera with OIS, a 50MP telephoto camera with OIS and an 8MP wide camera. Vivo’s overview identifies the telephoto as ZEISS-branded and says it takes photos with 3x, 10x and 20x zoom; that is vivo’s product claim, not an independent image-quality assessment. The Y21 5G page lists a 50MP rear camera, a 0.08MP auxiliary camera and a 5MP front camera.

Battery capacity, charging and protection
Both India specification pages list a 6,500 mAh typical battery, so capacity alone does not separate the phones. The listed wired charging rates differ: 90W for the X300 FE and 44W for the Y21 5G. Vivo’s X300 FE overview also lists 40W wireless charging.
The X300 FE page lists IP68/IP69 ingress protection and a glass back; the Y21 5G page lists IP65 and a composite plastic back. These are the ratings and materials stated by vivo. They should not be treated as a warranty promise or as a guarantee of safety in any particular exposure or use.
What is the price difference?
No comparable current price is established by the cited official product pages, so a reliable price difference cannot be quoted here. Prices depend on country, configuration, seller and date. To compare them fairly, check current listings in one country and currency for the same seller type, and compare the specific RAM and storage variants you would actually buy. Do not treat an older launch price or the phones’ specification tiers as a current price comparison.

Which one should you choose?
- Choose the X300 FE based on its listed specifications if you want the higher-resolution AMOLED panel, the more advanced listed processor and memory/storage tiers, a dedicated telephoto camera, faster wired charging or wireless charging.
- Consider the Y21 5G based on its listed specifications if you prefer a larger screen, want microSD expansion, or need one of its listed 128GB configurations.
- Compare prices only after choosing the market and configuration. The official India specifications clarify the hardware comparison, but do not establish a current price gap.
