Which phone has the better display?
The Moto G57 Power lists a higher resolution: 2400 × 1080 pixels on a 6.72-inch screen, compared with 1600 × 720 on the vivo Y21 5G’s 6.74-inch display. The vivo panel is marginally larger diagonally, while the Moto’s listed resolution is substantially higher. Both manufacturers list refresh rates of up to 120 Hz. These specifications indicate a resolution advantage for the Moto on paper; they do not establish differences in brightness, color, or viewing quality.

Motorola lists a 7,000 mAh battery and 30 W charging for the Moto G57 Power. vivo lists 6,500 mAh and 44 W for the Y21 5G. The Moto therefore has greater stated capacity, while the vivo has the higher rated charging wattage. Capacity and wattage are specifications, not comparable tests of battery life or time to recharge; no head-to-head runtime or charging results are established here.

Processor, RAM and storage: match the variants
The manufacturers list different chipsets: Snapdragon 6s Gen 4 for the Moto and Dimensity 6300 for the vivo. Motorola’s UK page pairs its listed phone with 8 GB RAM and 256 GB storage. vivo India’s page lists the Y21 5G with 4 GB, 6 GB or 8 GB RAM and 128 GB storage. The 91mobiles India comparison also lists a 128 GB Moto configuration, which shows why a UK specification should not be assumed to describe every India variant.
These processor and memory specifications alone do not establish which phone performs better. A fair price comparison requires the same market and the specific RAM/storage configurations being considered. The 91mobiles page lists an AnTuTu result for the Moto but no corresponding Y21 result, so it does not provide a controlled head-to-head performance comparison.

Camera hardware: the secondary camera is not equivalent
Motorola specifies a 50 MP main camera and an 8 MP ultra-wide camera on the rear, plus an 8 MP front camera. 91mobiles lists the vivo with a 50 MP main camera, a 0.08 MP secondary camera and a 5 MP front camera. The Moto’s secondary rear camera is explicitly an ultra-wide; the listed vivo secondary should not be treated as an equivalent ultra-wide camera. Megapixel counts describe resolution, not overall image quality, and the cited figures do not establish which phone takes better photos.
Water and durability ratings
Motorola’s UK specification page lists IP64, MIL-STD 810H and Gorilla Glass 7i; vivo India’s page lists IP65. These are manufacturers’ published specifications, and regional specifications may vary. Do not interpret either phone’s rating as making it waterproof.

Price difference: what the listed figures do and do not show
When observed, 91mobiles’ comparison price panel showed ₹20,999 for the Moto G57 Power and ₹21,699 for the vivo Y21 5G—a ₹700 difference, with the Moto listed lower. The page’s prices and configuration details can change, and these figures are not a confirmed current offer or a guaranteed like-for-like comparison. The source does not establish a price-check date that would make them reliable as current retail prices, so treat them only as a snapshot from the comparison page.
Before choosing on price, check the live listing for each phone and compare the same country, RAM/storage configuration, seller type, warranty, and offer terms. The quoted manufacturer pages are regional references, not substitutes for confirming a local retailer’s exact variant and warranty.

How to choose between them
- Prioritize listed screen resolution: the Moto G57 Power’s published resolution is higher, while the vivo screen is slightly larger diagonally.
- Prioritize capacity or rated charging: the Moto lists the larger battery; the vivo lists the higher charging wattage. Neither specification alone predicts real-world battery life or recharge time.
- Compare the exact memory configuration: verify RAM and storage for the local Moto and vivo listings before comparing prices.
- Consider camera type, not just megapixels: Motorola specifies an ultra-wide rear camera; the cited vivo listing does not establish an equivalent secondary camera.
- Check local protections and support: confirm the applicable regional specifications, software support terms, warranty and current offer with the seller or manufacturer.
