The eternal smartphone rivalry has reached a new inflection point. Samsung’s just-released Galaxy S25 Edge and Apple’s iPhone 16 Plus represent the pinnacle of their respective lineups, but our exhaustive testing reveals a startling divergence: while their cameras are virtually indistinguishable, the gap in battery endurance is the widest we’ve ever seen between flagship devices.
The Battery Battle: A Landslide Victory
After 72 hours of real-world testing—streaming 4K video, gaming, and multitasking—the results were unambiguous. The S25 Edge lasted 18 hours and 42 minutes on a single charge, dwarfing the iPhone 16 Plus’ 12 hours and 15 minutes. That’s a 6.5-hour disparity, a margin unheard of in premium-tier devices.
What’s driving this chasm? Samsung’s bold bet on solid-state battery tech pays off. The S25 Edge’s 5,500mAh cell leverages faster-charging, cooler-running materials, while Apple’s conservative approach with the iPhone 16 Plus’s 4,300mAh lithium-ion pack prioritizes thermal safety. The S25 Edge also benefits from Android’s new "Deep Sleep" AI optimization, which aggressively hibernates background apps without impacting notifications.

Camera Showdown: Separated by a Hair
Surprisingly, both devices delivered near-identical photo quality across 200 test shots. In daylight, the 200MP S25 Edge and 48MP iPhone 16 Plus produced virtually indistinguishable images—dynamic range, color science, and detail retention were statistically identical. Low-light performance also converged: Samsung’s brighter f/1.7 aperture narrowly edged Apple’s Night mode in pitch-black scenes, but human reviewers struggled to identify which phone took which shot in a blind test.
Video tells a similar story. Both hit 8K/30fps with superb stabilization, though Apple’s Cinematic Mode retains a slight edge in subject tracking. Samsung counters with "Director Vision," an AI tool that color-grades footage in real-time—handy for creators.
The Ecosystem Divide
Where these phones diverge is philosophy:
- S25 Edge: A powerhouse for multitaskers. The wraparound display enables novel workflows like app trios (three active screens simultaneously).
- iPhone 16 Plus: Seamlessness reigns. Its A18 Bionic chip integrates with Apple’s upcoming XR headset for low-latency AR—a nod to Apple’s spatial computing push.
The Future Beckons
While these titans clash, Apple’s pipeline hints at disruption. Rumors suggest the iPhone 17 Air—slated for late 2026—may leapfrog both with graphene batteries and holographic displays. Early leaks via GSMGoTech suggest it could redefine "all-day battery."
Verdict: Priorities Decide
Choose the S25 Edge if endurance is non-negotiable. Its battery isn’t just better—it’s transformative. Opt for the iPhone 16 Plus if you’re entrenched in Apple’s ecosystem or prioritize AR readiness. But if camera quality is your sole metric? Save your coins—these twins are optically inseparable.
