There is no single worldwide answer to “Redmi Note 15 Pro vs Nothing Phone 3a”: Xiaomi sells Redmi Note 15 Pro variants with different specifications, and prices depend on market, storage and seller. In India, a 2026 91mobiles comparison listed the Redmi at ₹31,999 and the Nothing Phone (3a) at ₹24,999—a ₹7,000 snapshot gap, not a guaranteed current offer. First verify whether the Redmi listing is for the 4G or 5G model and compare the same storage tier and sales channel.
Price difference: what the available listings show
The India comparison page listed the Redmi Note 15 Pro at ₹31,999 and the Nothing Phone (3a) at ₹24,999, making the Nothing listing ₹7,000 lower at the time accessed in 2026. These are local listing prices, not confirmed current offers or a universal price difference; the comparison does not establish the exact Redmi 4G/5G identity for the listed SKU. Check the seller’s model number, storage, stock and warranty before deciding. 91mobiles comparison

In the UK, Nothing’s product page showed £329 for the Phone (3a) with 12GB RAM and 256GB storage when accessed in 2026, but marked it sold out. That is a different market and configuration; it should not be compared directly with the India listings or treated as evidence of current availability. Nothing UK product page

Display and performance: choose the exact Redmi version first
If the Redmi is the 5G model
The UK-listed Redmi 5G has a 6.83-inch 2772 × 1280 display, compared with the 6.77-inch 1080 × 2392 120Hz panel reported for the Nothing. On listed size and resolution, the Redmi has the larger, higher-resolution screen. Xiaomi lists a Dimensity 7400-Ultra for this Redmi; the comparison reports a Snapdragon 7s Gen 3 for the Nothing. Those processor names alone do not establish which phone is faster in everyday use or demanding apps.

If the Redmi is the 4G model
The global Redmi 4G listing has a 6.77-inch 2392 × 1080 display, much closer in size and resolution to the Nothing panel. Its Helio G200-Ultra and lack of 5G make it a different proposition from the UK Redmi 5G. Do not use the 5G model’s screen or chipset details to assess a 4G listing.

Both Redmi variants list a 200MP OIS main camera and an 8MP ultrawide. The Nothing Phone (3a) system reported by 91mobiles adds a dedicated 50MP telephoto camera to its 50MP main and 8MP ultrawide cameras. That gives the Nothing a distinct listed camera type for telephoto framing; the Redmi emphasizes main-camera resolution and optical stabilization. Megapixel counts and camera hardware do not prove which phone takes better photos, and the sources here do not provide comparable image testing.

Battery, charging and durability
Xiaomi lists typical capacities of 6,500mAh for the 4G Redmi and 6,580mAh for the 5G Redmi, with 45W charging on both. The 91mobiles comparison lists 5,000mAh and 50W charging for the Nothing. Capacity and charging wattage are specifications, not direct measures of real-world battery life or time to recharge.
The same source lists IP64 for the Nothing, while Xiaomi lists IP65 for the global Redmi 4G and IP66/IP68/IP69/IP69K for its UK Redmi 5G. These certification labels describe different levels and test conditions; none means a phone is waterproof in every situation. Check the exact model’s regional warranty terms before exposing it to water or dust.

Which should you buy?
- Choose the Nothing Phone (3a) if its local price is lower and a dedicated telephoto camera matters to you. The India listings cited here favor Nothing by ₹7,000, but verify today’s price and the exact Redmi SKU.
- Consider the Redmi Note 15 Pro 5G if you want the larger, higher-resolution display and larger listed battery capacity, and the price and network bands suit your market.
- Consider the Redmi Note 15 Pro 4G only if you are comparing that specific model; it is not the 5G version and has different connectivity, chipset and protection specifications.
- Before paying, match country, model number, storage, seller, warranty and current availability. A price comparison across different variants or storage tiers can be misleading.
Product prices and availability are accurate as of the date/time indicated and are subject to change. Any price and availability information displayed on Amazon at the time of purchase will apply.
