Design and Display: The Visible Changes

This time around, Xiaomi decided to switch up the design language significantly with the Redmi Note 15 4G. Last year's Redmi Note 14 4G looked more like an iPhone with its camera layout. Personally, I am not a fan of companies trying to imitate another brand; it tends to look kinda generic.

For the Redmi Note 15 design, Xiaomi has moved the cameras to the center in a circular shape. I know this is a polarizing choice—most people might not like it, but I am actually a big fan of that symmetrical camera layout. Looking closely at the render images, I can also tell the Redmi Note 15 4G has visibly narrower bezels compared to the slightly chunky bezels we saw on the Redmi Note 14 4G.

In terms of size, the new model is slightly larger at 6.77 inches, whereas the Note 14 4G is a bit more compact at 6.67 inches. The screen architecture has also changed; the Note 15 4G is curved, while the Note 14 4G was flat. I know many of you hate curved displays because of accidental touches or fragility, but if you plan to buy the Note 15 4G, you will have to get used to it.

The biggest upgrade, however, is the display brightness. The Note 14 4G had a peak brightness of 1800 nits, which was decent, but the Note 15 4G pushes this to a massive 3200 nits. This is more than enough for comfortable outdoor use, even under the direct Kenyan sun.

Durability and IP Rating: Is it Waterproof?

On durability, the Note 14 4G came with Corning Gorilla Glass 5. While it’s not yet officially confirmed which glass the Note 15 4G uses, it is speculated to come with the same Gorilla Glass 5 protection.

There is a slight confusion regarding the ingress protection. The Note 14 4G had an IP54 rating. This time, Xiaomi has bumped that to IP64 dust and water protection. This actually means the device is better sealed against dust (Dust Tight) compared to the predecessor, though the water resistance remains at a "splash-proof" level. So, while it is an upgrade, please don’t dip it in water or take it to the shower.

Performance Benchmarks: Helio G100 vs Helio G99

If you are looking for a massive performance boost, you might be disappointed. Xiaomi didn’t make any major performance improvements in the new Redmi Note 15 4G. The new Helio G100 chipset is architecturally very similar to the older Helio G99-Ultra found in the Note 14.

When we look at performance benchmarks, there is no major bump; we are seeing roughly a 1% increase in single-core scores and about 2% in multi-core scores. In real-world usage, specifically while playing games like PUBG or COD Mobile, you will definitely not note any difference in performance. You might see a slight bump in FPS stability, but nothing revolutionary. Both devices also utilize UFS 2.2 storage, so app opening speeds will be identical.

Camera Capabilities: A Familiar Setup

On the camera side of things, we don’t actually get an upgrade. Xiaomi has opted to use the same 108MP main camera paired with a gimmicky 2MP macro sensor, which, let's be honest, no one really uses.

At the front, it is the same story: a 20MP selfie shooter with no real hardware upgrades. As for video recording settings, both the rear and the selfie cameras are capped at the same resolution: up to 1080p at 60fps for the rear camera and 30fps for the front-facing camera. If you were hoping for 4K recording, you'll have to look elsewhere.

Battery Life and Charging Speed Test

We do see a slight bump up in the battery department. The Note 14 4G had a 5500mAh battery, which was already above the industry standard. However, the Redmi Note 15 4G battery comes in at a huge 6000mAh. This is more than enough for an average person to get through an entire day or even a day and a half on a single charge.

The downside comes in charging speeds. Both phones are stuck with relatively slow 33W charging. In 2025, Xiaomi could have at least included a 45W charger to handle that massive capacity. I guess you can’t have a bigger battery and a fast charger at the same time at this price point; Xiaomi had to sacrifice one.

The Verdict: Should You Upgrade?

After comparing the specs and features, I honestly don’t see many meaningful upgrades between these two generations. First of all, the chipset is practically the same, so your day-to-day performance and gaming experience will be identical. There is also no major upgrade on the cameras; the quality might be slightly tuned on the Note 15 via software, but I don’t expect jaw-dropping results.

Buy the Redmi Note 15 4G if:

1. You prioritize maximum battery life (6000mAh).

2. You need the brightest screen possible (3200 nits) for outdoor work.

Stick with the Redmi Note 14 4G if:

1. You want to save money (the Redmi Note 14 price is likely dropping now).

2. You prefer a flat display over a curved one.

3. You want a slightly smaller, more manageable phone.

4. The minor performance difference is negligible for your needs.
