Introduction
The Samsung Galaxy S25 Edge is a stunning piece of technology, boasting a delicately thin frame and impressive specifications. However, its battery life has raised concerns among users and reviewers alike. In this blog post, we'll delve into the battery performance of the Galaxy S25 Edge and explore why it might not be the best choice for those seeking all-day battery life.
The Thin Frame and Battery Capacity
The Samsung Galaxy S25 Edge's thin frame is undoubtedly one of its most attractive features. However, this design choice comes at a cost. The phone's 3,900mAh battery capacity is relatively conservative for a 2025 flagship smartphone, especially when compared to its siblings.
Comparison with Other Models
- Galaxy S25 Plus: Houses a sizable 4,900mAh cell.
- Galaxy S25: Nudges ahead of the Edge with a 4,000mAh battery.
The Edge's larger display with a higher QHD resolution and a more demanding 200MP camera are factors that could draw more power than those in the regular S25.
Battery Life Benchmarks
Samsung claims that the Edge should have battery life somewhere between the Galaxy S24 and S25. However, testing has found this to be rather optimistic. Let's take a look at the results from automated battery longevity tests, all conducted at a consistent display brightness of 300 nits.
Test Results
- Video Recording and Playback: Roughly 20% reduction compared to the regular S25.
- Zoom Call Duration: 27% worse performance compared to the regular S25.
- Web Browsing: About an 8% decline compared to the regular S25.
The Edge's beefier specs drain the 3,900mAh battery even faster than the S25, leading to disappointing screen-on time.
Real-World Battery Life
Setting aside the comparisons for a moment, let's focus on screen-on time itself. Based on tests, the Galaxy S25 Edge delivers:
- About four and a bit hours of constant content capture.
- Seven to eight hours of moderate use (like web browsing and video calls).
- Up to 17 hours of offline 4K video playback.
These figures aren't terrible in isolation but fall an hour or two behind its siblings. And keep in mind that this is under ideal, out-of-the-box conditions. Add background tasks, heavy data use, or gaming, and things quickly deteriorate.
Long-Term Battery Health
Samsung has built the Edge with a battery capacity that clearly cuts it very fine for a full day of use. While the Galaxy S25 Edge might manage modest usage today, consider how it will perform after two or three years, especially at a price point of $1,100. A modest decline to 90% of its original battery capacity after two years could already spell trouble; a drop to 80% will have you reaching for a charger before the day is over.
Additionally, the thin metal frame heating up frequently during use not only accelerates battery degradation but can also cause the battery to discharge inefficiently and increase self-discharge. This might explain why the phone seems to perform particularly poorly in demanding tests, like Zoom calls, and why Samsung has stuck to sluggish 25W charging again.
Conclusion
The Samsung Galaxy S25 Edge is a beautiful and powerful smartphone, but its battery life leaves much to be desired. If you plan to keep your next phone for a few years, you might want to steer clear of Samsung’s ultra-thin flagship. The data clearly shows that the Galaxy S25 Edge's battery life is inferior to its siblings, and its long-term performance is a cause for concern.
