Galaxy S24 vs. S25: What’s New and Worth the Upgrade

Samsung’s Galaxy S lineup continues to evolve each year, but not every update changes how a phone feels in daily use. When comparing the Galaxy S24 and Galaxy S25 families in 2026, the decision is less about buying the newest phone and more about choosing the model that best fits how you use your device today and how long you plan to keep it.

This is not a simple one-to-one comparison. Samsung now offers nine different Galaxy S models across these two generations, each aimed at a slightly different type of user. Understanding where each model fits helps avoid overbuying features you may never use or underspending on areas that matter to you.

This guide compares design, performance, cameras, software support, and long-term value across the entire Galaxy S24 and S25 lineups to help you decide whether upgrading makes sense or if holding onto your current phone is the better move.

Galaxy S24 and S25 Lineups

Samsung structures the Galaxy S lineup to cover a wide range of needs, rather than offering a single flagship for everyone.

Galaxy S24 Lineup

• Galaxy S24 FE
• Galaxy S24
• Galaxy S24+
• Galaxy S24 Ultra

Galaxy S25 Lineup

• Galaxy S25 FE
• Galaxy S25
• Galaxy S25+
• Galaxy S25 Ultra
• Galaxy S25 Edge

At a high level, the lineups break down like this:

• FE models focus on value, offering large displays and solid performance without the highest-end hardware.
• Standard models prioritize balance, combining flagship performance with compact, easy-to-handle designs.
• Plus models increase screen size and battery capacity for users who want more room to work and watch.
• Ultra models deliver Samsung’s most advanced camera systems, displays, and added features like S Pen support.
• Edge, introduced with the S25 lineup, emphasizes a slim, lightweight design while still offering premium hardware.

Design and Display Differences Across All Models

Samsung has chosen refinement over redesign for both generations. While the overall look remains familiar, differences in screen size, resolution, and weight have a noticeable impact on everyday comfort and usability.

Display and Size Overview

How These Differences Affect Real Use

• Compact phone users will feel most comfortable with the S24 or S25.
• Big-screen users who want sharp visuals without Ultra weight may prefer the S24+, S25+, or S25 Edge.
• Ultra models offer the most immersive displays, but the added weight is noticeable during long use.
• S25 Edge stands out by pairing a large, high-resolution display with a much lighter frame, which appeals to users focused on portability.

Performance and Hardware Differences

Performance upgrades often drive upgrade decisions, but in practice, both generations are capable of handling modern apps, multitasking, and media consumption in 2026.

Processing and Memory

• Galaxy S25 Edge, S25, S25+, and S25 Ultra use the Snapdragon 8 Elite for Galaxy (3nm) octa-core processor paired with 12 GB of RAM, designed for improved efficiency and AI-assisted features.
• Galaxy S25 FE runs on the Exynos 2400 with 8 GB of RAM, offering a balance between performance and cost.
• Galaxy S24 FE uses a deca-core processor with 8 GB of RAM.
• Galaxy S24 and S24+ include 8 GB of RAM, while the S24 Ultra increases this to 12 GB.

In day-to-day use, the performance gap between S24 and S25 models is modest. Users moving from older devices like the S21 or S22 will notice a much bigger improvement than those upgrading from an S24.

Battery Life and Long-term Endurance

Battery capacity plays a major role in how long a phone remains practical as it ages.

Key considerations:

• Ultra models remain the safest choice for heavy users who rely on their phones all day.
• Plus models offer a strong balance of size and endurance.
• S25 Edge prioritizes slimness over battery capacity, which may not suit heavy streaming or gaming users.

Camera System Differences By Tier

Samsung’s camera strategy remains consistent across both generations, with major differentiation at the Ultra level.

Rear Camera Overview

Which Camera Setup Makes Sense?

• FE, standard, and Plus models suit everyday photography and casual video.
• Ultra models are best for zoom, flexibility, and camera-first users.
• S25 Edge offers a strong main camera in a thinner body, but it is not designed for heavy zoom use.

Software Support and Longevity

Samsung continues to offer extended security updates across both generations.

• S24 FE receives security updates through October 2031.
• Most S25 models extend into 2032, with slight variation by device.

For users who keep their phones longer, that added support window can be meaningful. For those who upgrade more frequently, the S24 lineup still offers plenty of runway.

Which Model Tier Makes Sense For You?

Who are the FE models for?

FE models work well for users who want a large display, solid cameras, and dependable performance without paying for premium hardware they may not need.

Standard vs. Plus Models

Standard models suit users who value portability, while Plus models make sense for those who read, stream, or multitask frequently and want a larger screen and battery.

When is Ultra Worth it?

Ultra models are best for camera-focused users, heavy multitaskers, and anyone who wants the most future-proof option in the lineup.

Where the S25 Edge Fits

The S25 Edge is ideal for users who want a large, sharp display in a lighter, slimmer form factor, even if that means compromising on battery size.

Price, Value, and Resale Considerations

Over time, certain patterns hold true:

• Newer models cost more upfront.
• Ultra models tend to retain value longer.
• Certified pre-owned devices often offer strong value.

Mobile Klinik’s guide to refurbished phone grades helps clarify what to expect when considering pre-owned devices.

The Practical Takeaway for 2026

Both the Galaxy S24 and S25 lineups remain strong choices in 2026. The S24 family emphasizes value and stability, while the S25 lineup focuses on lighter designs, refined performance, and broader model choice.

The best upgrade is the one that fits how you actually use your phone, not the one with the longest spec list.
