Best Small Smartphones in November 2025

Updated, rewritten in English, and stylistically refined analysis of “compact” flagships (up to ~6.3 inches), their compromises, real battery tests, and one-handed ergonomics.

Redistribution of Compactness Standards

The market has shifted since the era of the “iPhone mini” towards 6.1–6.3 inch screens: this size allows for a powerful SoC, larger camera sensors, and a “decent” battery. Therefore, in November 2025, the axis of the “small” flagship revolves around three priorities: maximum portability (e.g., “Galaxy S25”), highest endurance (e.g., “Xiaomi 15“), and AI + computational photography (e.g., “Pixel 9”).

Absolute Leaders by Categories

• Compactness and Weight: “Samsung Galaxy S25” (146.9 × 70.5 × 7.2 mm; ~162 g) – one of the narrowest and thinnest Android flagships. It is extremely convenient for one-handed operation, but limits battery capacity and cooling.
• Battery Endurance: “Xiaomi 15” with a 5240 mAh battery—a strategically larger body in exchange for the best endurance.
• AI and Camera: “Google Pixel 9” – the strongest computational photography and AI features with Tensor G4, while maintaining a ~6.3 inch format and a 4700 mAh battery.
• Best Price in Lithuania/EU: The base 128 GB version of “Galaxy S25” in Lithuania starts from ~€551.44 (data from price comparison portals).

The modern “small” flagship trilemma remains: size ↔ battery ↔ thermal management. The thinnest bodies statistically experience thermal throttling more often and have shorter endurance in intensive tasks.

6.3 inches – a Practical Demarcation

Manufacturers are increasingly less likely to release “ultra” small flagships—instead, base models have stabilized around 6.1–6.3 inches. This is a compromise that allows for maintaining performance and acceptable endurance. Huge “Ultra/Pro Max” (~6.7–6.9 inches) are not considered compact in this analysis.

Main Competitors

• Samsung Galaxy S25 (6.2”): a benchmark for ergonomics in the Android world (146.9 × 70.5 × 7.2 mm; ~162 g).
• Apple iPhone 16 (6.1”): the closest competitor in dimensions, but thicker and wider than the S25 (battery capacity ~3561 mAh, according to teardown/registry data).
• Xiaomi 15 (6.36”): the largest on the list, yet still “compact”; 5240 mAh battery – a clear endurance advantage.
• Google Pixel 9 (6.3”): 152.8 × 72.0 × 8.5 mm; 198 g; 4700 mAh; focus – AI and computational photography.

Market Dynamics

The niche for “small” flagships is narrowing – some historical lines (e.g., previous “compact” models) are no longer being updated. Consumer choice is naturally shifting towards optimal 6.1–6.3 inch models.

Foldable “Flip” – Small in Pocket, Big on Screen

If pocket format is the priority, the “flip” offering is attractive: for example, the “Motorola razr 60 Ultra” has an external screen of 4.0 inches, allowing for many tasks without opening the internal screen. However, in Europe, it remains a niche – the market share is small and maturity is not yet complete (price/durability).

V. Performance, Thermal Management, and Real Battery Tests

Why Thinness Often “Eats” Endurance

Thinner bodies (e.g., 7.2 mm “Galaxy S25”) have less space for the battery and cooling, so thermal throttling occurs more frequently under sustained loads. The strategy chosen by the “Pixel 9” is to limit the long-term SoC “peak” in exchange for stability, AI efficiency, and lower temperatures.

In a one-time but representative “battery drain” test, the “Pixel 9” outperformed the “iPhone 16” and “Galaxy S25”: approximately ~6:56, ~6:07, and ~5:36 (H:MM). Methodologies differ between publications, but this result illustrates the importance of optimization rather than just battery capacity.

Software = Half the Success

Even in 6.2–6.3 inch devices, software ergonomics have a huge impact. “Samsung One Hand Operation+” allows assigning side gestures for “back”, quick launches, screenshots, or flashlight; it is one of the most versatile one-handed control tools. “iOS” “Reachability” lowers content, but lags in terms of versatility and adaptability.
