realme P4 Power 5G vs Redmi Note 15 Pro 5G (2026)

realme P4 Power 5G vs Redmi Note 15 Pro 5G price in India

Recent Indian market references in September 2026 place the realme P4 Power 5G around ₹30,390 for an 8GB + 128GB listing and the Redmi Note 15 Pro 5G around ₹31,999 for an 8GB + 128GB listing. Prices can vary by colour, storage, seller, card offer and sale period, so the final Amazon checkout price matters more than a static reference.

Quick specification comparison

The biggest hardware difference is easy to understand. The realme P4 Power 5G is built around endurance, with a 10,001mAh battery and 80W charging. Redmi uses a smaller 6,580mAh battery but gives you a much higher-resolution 200MP OIS main camera, a sharper 1.5K AMOLED panel and a more aggressive durability specification sheet.

Display: 144Hz realme vs sharper 1.5K Redmi

The realme P4 Power 5G uses a 6.8-inch AMOLED display with up to 144Hz refresh rate and a 1280×2800 resolution. This makes it attractive for users who value smooth scrolling, gaming responsiveness and a large viewing area.

The Redmi Note 15 Pro 5G uses a 6.83-inch 1.5K AMOLED panel with a 2772×1280 resolution and up to 120Hz refresh rate. Xiaomi also lists HDR10+, Dolby Vision and high peak brightness under specified conditions.

Performance: very similar chipset class

Both phones use a Dimensity 7400-series platform. realme lists the Dimensity 7400 Ultra 5G, while Xiaomi lists the Dimensity 7400-Ultra built on a 4nm process. That means chipset naming alone should not decide this comparison.

For normal apps, streaming, social media and multitasking, both target the same upper mid-range performance zone. Gamers should look at sustained performance, thermals and battery behaviour, where the realme’s very large battery may be useful for longer sessions.

Camera: Redmi has the headline hardware advantage

The realme P4 Power 5G uses a 50MP OIS main camera and an 8MP ultra-wide camera, with a 16MP front camera. The Redmi Note 15 Pro 5G uses a 200MP OIS main camera and an 8MP ultra-wide camera, with a 20MP front camera and 4K recording support.

If photography is one of your main priorities, the Redmi is the easier phone to shortlist on specifications alone. The 200MP main sensor gives more room for high-resolution capture and cropping, although image processing, lighting and shooting style still matter.

Battery and charging: realme’s defining advantage

The realme P4 Power 5G’s standout feature is its 10,001mAh battery. realme also lists 80W charging, making this phone particularly relevant for heavy users, long travel, gaming sessions and buyers who simply want to charge less often.

The Redmi Note 15 Pro 5G has a 6,580mAh silicon-carbon battery with 45W charging and up to 22.5W wired reverse charging support.

Durability and everyday handling

Xiaomi lists IP66, IP68, IP69 and IP69K ratings for the Redmi Note 15 Pro 5G under specified laboratory conditions, plus Gorilla Glass Victus 2. Redmi also weighs 210g according to Xiaomi’s official specifications.

The realme P4 Power 5G is heavier, around 219g in current specification references, which is unsurprising given its unusually large battery. Buyers who value a lighter phone may prefer Redmi, while buyers who value extreme battery capacity may accept the extra weight.

Software and updates

realme states that the P4 Power 5G comes with realme UI 7 and receives 3 Android OS updates with 4 years of software support. Xiaomi advertises 4 years of OS updates and 6 years of security updates for the Redmi Note 15 Pro 5G.

For users who keep their phone for many years, the Redmi’s longer advertised support window is an important practical advantage.
