The Samsung Galaxy S25 Edge is a stunning declaration in slim smartphone design, the epitome of a flagship experience – in order to maintain the exclusivity of the earlier statement behind a more physically expensive body. Featuring a sophisticated titanium frame, clear 6.7-inch AMOLED screen and flagship-level performance, the S25 Edge is targeting users who are looking for a unique design without compromise at the very top-end of its spec sheet, with some compromise elsewhere.
At the heart is the Snapdragon 8 Elite, Qualcomm’s 3nm monster chip which is all about grunt with a dual-cluster CPU — there are two insanely fast Oryon V2 Phoenix L cores clocked at 4.47GHz and six Phoenix M cores at 3.53GHz to help get you through life at a rapid pace. Powered by an Adreno 830 GPU, as much as 12GB of RAM, and up to 512GB of UFS 4.0 storage, the S25 Edge is more than up to the task for everyday multitasking and even the highest demanding mobile games. The benchmark scores are good and while there is some thermal throttling if you consistently push it for a long duration, naturally, the ultra-thin design too, but in daily use, the performance is very good.
The 6.7-inch LTPO AMOLED 2X screen is both sharp and smooth, at a resolution of 1440x3120 with a 120Hz adaptive refresh rate, and HDR10+ support. Gorilla Glass Ceramic 2 provides even more protection with a measured peak brightness of 1416 nits to help you see in the bright sun. It’s not the brightest panel out there, but it gets plenty bright for media consumption, and it has deep blacks and rich colours that make everything from scrolling to swiping feel that much more premium.
The S25 Edge’s design is definitely the area where it shines. Slimmer than ever – at 5.8mm thin it’s the firm’s slimmest ever Galaxy S flagship – but still solid and resilient, at 163g with IP68-certified water and dust resistance. The titanium frame feels great in the hand, and the uncluttered rear housing bares an increasingly rear-facing world that is future-facing and free of branding. Available in Titanium Icyblue, Titanium Silver and Titanium Jetblack, it’s a device that makes you take a second look without trying too hard.
Photography is led by a 200MP main camera, delivering detailed images in good lighting with decent dynamic range. Accompanied by a 12MP ultrawide, the setup lacks a dedicated telephoto lens, one of the phone’s few drawbacks. Still, the 2x sensor crop offers solid short-range zoom. Video recording capabilities are robust, supporting 8K at 30fps and multiple slow-motion modes. The 12MP front-facing camera provides clean selfies and sharp 4K video, ideal for casual creators and video calls alike.
Battery life, however, is where the S25 Edge shows its slim-profile trade-offs. The 3900mAh cell performs adequately in moderate use but may struggle to go the full day under heavy loads, especially when using mobile data or GPS. It supports 25W wired charging (55% in 30 minutes) and 15W wireless charging (Qi2 Ready), though rivals now offer faster speeds and larger capacities. While fine for the minimalist, power users may need a midday top-up or external battery.
The S25 Edge runs Android 15 with One UI 7, bringing Samsung’s latest AI features like Circle to Search, AI Select, and Generative Edit, along with seven years of OS and security updates. Software performance is smooth, and the addition of Samsung DeX and Ultra-Wideband (UWB) elevates productivity for those who like to do more with their phone.
With Wi-Fi 7, Bluetooth 5.4, stereo speakers, and an ultrasonic in-display fingerprint reader, the Galaxy S25 Edge covers all the premium essentials. It's a stunning choice for those who crave a lighter, sleeker handset, as long as they’re aware of the battery life compromise that comes with all that finesse.

2. Battery Life
In ViserMark’s battery life testing, the Samsung Galaxy S25 Edge achieved 34 hours of continuous usage, which translates to just over 1.5 days of real-world battery life under typical conditions. This result is solid, especially considering the Edge’s ultra-slim 5.8mm profile and smaller 3,900mAh battery.
Thanks to the Snapdragon 8 Elite chipset and Samsung’s One UI 7 power optimisations, the S25 Edge performs efficiently under balanced workloads. While it closely matches the regular Galaxy S25 (35 hours), it still underperforms against the Flagship/Pro Tier average of 40.91 hours, particularly during heavier tasks;
Despite this, the S25 Edge provides reliable day-to-day stamina for light to moderate users. Its appeal lies in the combination of featherweight design, flagship performance, and premium build quality, even if that comes at the cost of slightly shorter screen-on time compared to bulkier devices.
The Samsung Galaxy S25 Edge and the Samsung Galaxy S25 were analysed for battery consumption across various daily tasks using SmartViser's viSer and VWS Analytics Studio. The comparison highlighted differences in power usage for activities such as social media, calls, gaming, camera, and web browsing.
While both phones share the same Snapdragon 8 Elite chipset and One UI 7 software, the S25 Edge consumes significantly more power during social media use and outgoing calls, two tasks where its slimmer body and smaller battery seem to struggle with sustained connectivity and screen activity.
However, the Edge proves more efficient in several other areas, including gaming, download/upload, camera usage, and media playback. This suggests that Samsung has managed to optimise certain performance aspects on the Edge variant, likely leveraging improved tuning or reduced thermal throttling in short bursts.
Where the difference becomes most striking is in the Replay workload, where the S25 Edge consumes far more power than the standard model, suggesting its thermal envelope struggles to handle background-heavy or multitasking scenarios as efficiently.
For YouTube streaming and web browsing, the gap narrows again, but the Edge still tends to consume slightly more, consistent with its QHD+ resolution and higher pixel density, which push the GPU harder even in light tasks.
In conclusion, the Galaxy S25 Edge trades some endurance for its ultra-slim, high-res design, excelling in certain areas but clearly less suited for tasks requiring sustained processing or multitasking.
The Samsung Galaxy S25 Edge and Galaxy S25 Ultra differ sharply in power consumption across key usage scenarios. While both offer flagship performance with Snapdragon 8 Elite internals, their battery behaviour reflects distinct design priorities.
The Edge outperforms the Ultra in gaming, download/upload, camera use, and media playback, making it better suited for focused, short-session tasks. Both phones are nearly identical in YouTube consumption, suggesting similar screen efficiency for video playback.
However, the Ultra consumes significantly more power during outgoing calls and replay scenarios, indicating that its larger size and feature set may demand more from the battery during background tasks or extended multitasking. Social media and web browsing are the only areas where the Edge consumes slightly more, though the differences are minor and unlikely to impact real-world use significantly.
Overall, the Galaxy S25 Edge offers more efficient power usage in most scenarios, making it a compelling choice for users focused on balanced performance and portability. The Ultra, while more power-hungry, is still ideal for users demanding consistent high-end performance across the board.
The battery performance comparison between the Samsung Galaxy S25 Edge, Galaxy S25, Galaxy S25 Ultra, and the Flagship/Pro Tier average reveals key differences in energy consumption across everyday activities, offering a clear look at how each device manages power in real-world scenarios.
The Galaxy S25 Ultra, despite offering top-tier hardware and a premium QHD+ display, exhibits the highest current consumption across most tasks — particularly in outgoing calls and replay, where it significantly exceeds both its siblings and the average. It’s also the least efficient during gaming. That said, it does show some strengths: it matches the S25 Edge in YouTube playback and performs better than the average in camera usage, likely due to Samsung’s optimised image processing pipeline.
The Galaxy S25 Edge, on the other hand, demonstrates more refined power management overall. It consumes less power than the Ultra in every category except social media and web browsing. It leads in gaming, camera, media playback, and download/upload, where it consistently shows the lowest drain. Its only clear drawback is Web browsing, where it registers the highest power consumption across all tested devices. Social media power usage is also slightly above average but still in line with the S25 Ultra.
The standard Galaxy S25 sits somewhere in between, more efficient than the Ultra, though not as lean as the Edge. It handles camera, gaming, and upload/download tasks better than the Ultra but falls short of the Edge’s tighter energy control. Notably, it is more efficient than the Edge in social media and web browsing, two areas where the Edge dips.
In short, if battery efficiency is your priority, the Galaxy S25 Edge offers standout performance in tasks like gaming, camera, download/upload, and media playback, but it does not consistently outperform the Flagship/Pro Tier average. In fact, it draws significantly more current in high-frequency use cases.
In ViserMark’s battery efficiency testing, the Samsung Galaxy S25 Edge earned a full 1-leaf rating, indicating top-tier energy efficiency for a device in the flagship class.

Despite packing a high-resolution QHD+ display and the same Snapdragon 8 Gen 3 for Galaxy chip as the Ultra, the Edge benefits from its slimmer form factor, smaller 3,900mAh battery, and more thermally efficient design. These characteristics help reduce power draw in sustained workloads such as gaming, video playback, and camera use, contributing to longer-lasting real-world performance despite its compact build.
The 1-leaf rating highlights Samsung’s successful optimisation of both hardware and software on the Edge variant. For users who value efficiency without sacrificing performance, the Galaxy S25 Edge stands out as one of the most balanced and energy-conscious premium smartphones available.
According to ViserMark, the Samsung Galaxy S25 Edge has an estimated annual energy consumption of 3.7 kWh, matching the standard Galaxy S25 and performing slightly better than the Flagship/Pro Tier average of 3.8 kWh. While not the absolute lowest we've recorded, it still represents a strong result within the premium segment, especially considering its high-resolution display and flagship-grade internals.
This level of efficiency suggests that the S25 Edge strikes a smart balance between performance and power draw, ideal for users who want a capable daily driver with less impact on long-term energy use compared to more power-hungry flagships like the S25 Ultra (4.5 kWh).
In contrast, the Galaxy S25 Edge offers notable power savings without compromising on flagship-level performance. With efficient power management across most tasks and competitive annual energy consumption, it's a compelling option for those seeking a premium experience with better energy efficiency. While it may not boast the raw horsepower of the Ultra, it proves that you don’t need to burn through power to get a polished, high-end smartphone experience.
Who Should Buy the Samsung Galaxy S25 Edge?
The Galaxy S25 Edge is ideal for users who prioritise slim, premium design without giving up flagship-level features. Its ultra-thin 5.8 mm chassis, titanium build and vibrant QHD+ AMOLED display make it a standout choice for those who want style and performance in equal measure.
Battery efficiency is one of its strongest suits. Despite the smaller 3,900mAh cell, it manages better-than-expected endurance for light to moderate use. It leads in power management for gaming, downloads and media playback, and its annual consumption matches the Galaxy S25 while staying below the flagship category average.
It’s also well suited for users looking for long-term software support and versatile features like Samsung DeX and UWB. Content creators and casual gamers will appreciate its fast chip, fluid display and excellent camera for quick social sharing.
However, it’s less appropriate for those who rely heavily on video calls, navigation or intense multitasking, where power consumption rises noticeably.
