Redmi Note 15 Pro+ 5G Review: Xiaomi’s best mid-ranger takes on Pixel 9a

Xiaomi has a new phone aiming squarely at the Pixel 9a and Galaxy A56 5G. It seems to pack a fast processor, a strong camera, and an impressively huge battery to compete.

But are there any drawbacks? Let’s take a closer look.

Redmi Note 15 Pro+ 5G Design and Display

Soft touch back and a modern styling

Starting with the design, this is the faux leather version, featuring a soft-touch back and a really nice in-hand feel. The rest of the design follows the typical 2026 trend: flat sides, flat screen — a bit generic, but solid and well-built.The phone measures 163.3 × 78.3 × 8.2 mm, making it slightly wide with average thickness. Thanks to its IP68/IP69K rating, it’s protected against dust, can be submerged in water up to 1.5 meters, and even withstands high-pressure water jets. At 207 grams, it’s not exactly light, though still lighter than an iPhone Pro Max.

Above you can see the contents of the box, much richer than what you get with most other phones.

The 6.8-inch display is large, and the slim bezels give it a much more modern look—especially when compared to the Pixel 9a’s noticeably thicker borders.

In terms of biometrics, you get an optical fingerprint scanner at the bottom part of the screen. It’s fast and reliable, no problems while using it.

Redmi Note 15 Pro+ 5G Camera

Solid main camera

On the camera front, the Redmi Note 15 Pro 5G comes with a 200MP main camera with a 23mm lens and f/1.7 aperture, plus you have an 8MP ultra-wide camera with a 15mm lens and f/2.2 aperture. No telephoto camera here, and at this price some phones have that.

The main camera is clearly the star of the show, while the 8MP ultra-wide feels like an after thought – not much detail and not a great performer, definitely a bit of a disappointment.

By default, the main camera outputs 12MP photos, while an Ultra HD mode lets you shoot at the full 200MP resolution—at the cost of much larger JPEG files, roughly 20MB versus about 3MB normally.

Video Quality

Redmi Note 15 Pro+ 5G Performance & Benchmarks

No stutter

Compared to cheaper phones in the Redmi Note 15 series, this one finally feels like it runs with no stutter. That’s all thanks to the Snapdragon 7s Gen 4 4nm chip on board. The phone also comes with 8GB of RAM, decent, but we have seen some phones in this price bracket with 12GB.

CPU Performance Benchmarks:

Xiaomi’s star mid-ranger is still no match for the performance power of, say, the Pixel 9a and its Tensor G4 chip. The Redmi is nearly 40% lower in terms of both single and multi-core performance.

The gap is even wider if you look at the gaming performance. The Redmi barely reaches 1,000 points on the 3D Mark stress test, while the Pixel is more than twice as fast. If you care about playing intense games like Genshin Impact, the Pixel is clearly the better choice for performance.

The phone ships with HyperOS 2.0 based on Android 15, with an upgrade to HyperOS 3.0 and Android 16 already confirmed.

Redmi Note 15 Pro+ 5G Battery

Massive battery and impressive 100W charging

The real star of the show is the 6,500 mAh battery. It’s about 15% larger than the Galaxy A56’s and, in real-world use, comfortably lasts around two days. Very nice!

PhoneArena Battery Test Results:

Charging is officially rated at a mind-boggling 100 watts, which is better than all of its rivals. A full charge takes just 40 minutes, compared to an hour and a half or longer for other phones. Do keep in mind that you only get these fast speeds with a proprietary Xiaomi charger that is not included in the box.

There is no wireless charging on board, though, which is a bit of a downer.

Redmi Note 15 Pro+ 5G Audio Quality and Haptics

Sound quality is actually quite good as the phone gets quite boomy and unlike cheaper Redmis, here you have some hint of the lower frequencies too. The larger size of this phone is an advantage in this case compared to, say, the smaller Pixel 9a.

Haptics are a strong point, delivering tight, well-controlled vibrations that feel far more refined than what you usually get on cheaper phones.

Should you buy it?

The Redmi Note 15 Pro+ 5G clearly sets a high bar for battery life and charging speed compared to Galaxies and Pixels. It’s also a very fast phone, runs smoothly, and handles gaming well. Small touches like the IR blaster are a nice bonus.

On the downside, photo and video quality still lag slightly behind the competition, even if the gap is narrowing.

If this combination appeals to you, my recommendation is to wait for the expected discounts and grab it at a much better price.
