Samsung’s S26 lineup aims for a thinner, sleeker flagship family
New leaks suggest Samsung is trimming the waistline of its next flagship phones without sacrificing core features. The rumored Galaxy S26 series — expected in January 2026 — reportedly makes significant reductions in thickness across the Pro, Edge, and Ultra models while retaining large batteries, premium cameras, and durability targets that matter to power users and professionals.
Key product features and leaked dimensions
Slimmer chassis across models
According to internal prototype measurements, the S26 Pro is said to measure roughly 6.7mm versus 7.2mm on the S25 base. The S26 Edge could be an industry-thin 5.5mm (down from 5.8mm), and the camera-focused S26 Ultra is reportedly around 7.8mm compared with the S25 Ultra’s 8.2mm. These slimmer profiles are notable for the flagship segment and reinforce Samsung’s focus on industrial design and ergonomics.
Battery, camera and stylus considerations
Despite the reduced thickness, the S26 Edge is tipped to include a larger 4,200mAh battery (up from 3,900mAh), signaling engineering improvements in battery density and internal layout. The S26 Ultra remains the platform for the 200MP camera and upgraded charging hardware, while the integrated S Pen constrains how thin the Ultra can go unless Samsung redesigns the stylus or its housing.

Comparisons and advantages
When stacked against the S25 family, the S26 models promise better ergonomics and portability without a trade-off in battery life or flagship camera performance. Samsung appears to be positioning the series against thin rivals like the rumored iPhone 17 Air, which is expected to target around 5.5mm. For users, a slimmer Galaxy could mean improved one-handed use, lighter commuting phones, and a sleeker aesthetic that still supports power-user features.
Use cases and market relevance
Photographers and content creators stand to benefit from the Ultra’s 200MP hardware and upgraded charging, while productivity users will value the S Pen-enabled workflow on the Ultra. Travelers and everyday consumers gain from the Edge’s boosted battery in a thinner frame. From a market perspective, Samsung’s rumored pricing appears to mirror current tiers — estimated at $799 for the Pro, $1,099 for the Edge, and $1,299 for the Ultra — though a price adjustment is possible given the new 'Pro' branding and design refresh.
What to watch before launch
These figures come from prototype data and may change ahead of an official January 2026 reveal. Key areas to monitor include final thickness tolerances, charging spec confirmations, battery longevity in real-world use, and whether Samsung will retain or redesign the S Pen system on the Ultra.
