Samsung Galaxy A57 vs Redmi Note 15 Pro: Which Mid-Ranger to Choose in 2026?

Around €330, two approaches go head to head: the Samsung Galaxy A57 5G, playing the reassuring-brand card with a premium design and above all an exceptional six years of software support, and the Redmi Note 15 Pro, stacking the spec sheet — 200 MP sensor, large screen, huge battery — to offer the most for the money. Should you pay for Samsung peace of mind or Xiaomi’s spec overkill? Here, criterion by criterion and use case by use case, is everything that sets them apart.

At a glance: the match in one table

Design, display and handling

The Galaxy A57 nails the finish: aluminum frame, Gorilla Glass Victus+ back, very slim profile (6.9 mm) and light. Its 6.7-inch Super AMOLED Plus FHD+ 120 Hz screen is bright and pleasant, with Samsung’s Vision Booster for outdoor readability. The Redmi Note 15 Pro offers a larger screen (6.83 inches) at 1.5K resolution, ideal for media, and reinforced water resistance. Both deliver fine display quality; Samsung bets on compactness and finish, Xiaomi on screen size.

Performance and everyday use

On paper, the Redmi’s Dimensity 7400 Ultra is a touch faster than the Galaxy A57’s Exynos 1680, especially in gaming where the Xiaomi holds demanding titles a bit better. But in everyday use — social media, browsing, messaging, streaming — both are smooth and perfectly sufficient. Samsung makes up for it with mature software optimization and a very polished One UI interface, while Xiaomi’s HyperOS is feature-rich but ships with a few pre-installed apps. Occasional gamer: the Redmi has a slight raw edge; fan of a clean, well-supported interface: Samsung.

Camera and video

Two strategies. The Redmi Note 15 Pro bets everything on its 200 MP sensor that, in daylight, captures huge amounts of detail and allows nice crops. Without optical stabilization, however, it’s less comfortable in low light and video. The Galaxy A57 favors a 50 MP sensor with optical stabilization (OIS), backed by a real ultrawide and Samsung’s Nightography mode: more consistent evening shots and more stable video. Verdict: for ultra-detailed daytime photography, the Redmi; for low-light consistency and video, the Galaxy A57.

Battery and charging

The Redmi Note 15 Pro packs a more generous battery (6,580 mAh versus 5,000 mAh), giving it the endurance edge: it more easily lasts two days with moderate use. Both charge at 45 W, at comparable speed. If battery life is a priority, the Redmi wins; the Galaxy A57 still comfortably lasts a full day and beyond.

Software and support: Samsung’s master card

This is where the Galaxy A57 hits hard: six years of Android and security updates, a rare promise in this price range and superior to what Xiaomi offers on its Redmi phones. In practice, your phone stays up to date and secure far longer, with better resale value. For anyone who keeps their phone for a long time, it’s a decisive argument in Samsung’s favor.

Price and availability

Both sit around €330 in their entry configuration. At equal storage, the Redmi offers more space (256 GB) and a bigger battery; the Samsung bets on brand, finish and above all software longevity. Price doesn’t decide it: your priority does.
