Weighing 215 grams, the device matches the physical dimensions of its predecessor while introducing a larger 3,000-nit peak brightness, a 50-megapixel ultra-wide camera, and an improved internal display featuring an anti-reflective coating and a less visible crease.
Design Evolution and Hardware Dimensions of Galaxy Z Fold8 Ultra
The device measures 158.4 × 72.8 × 8.9 mm when closed and weighs 215 grams, keeping identical external proportions to the preceding Galaxy Z Fold7, according to published testing data. Upon opening, the thickness decreases slightly from 4.2 mm to 4.1 mm. Despite holding the same weight as last year’s model, Samsung integrated a 600 mAh larger battery alongside a titanium reinforcement layer inside the display structure. Reviewers note that the redesigned Armor FlexHinge offers a smooth action, though the hinge stops holding the device stationary at an angle around 110 degrees, unlike previous iterations. The side-mounted fingerprint reader remains embedded in the power button, while durability stays capped at an IP48 rating, leaving the device vulnerable to fine dust and sand.
Pro Tip: When unfolding the device one-handed, leverage the redesigned internal bezel bevels and the newly calibrated hinge resistance to grip the chassis more naturally than on last generation hardware.
Display Enhancements and Anti-Reflective Technology
Both screens utilize Dynamic AMOLED 2X panels with an adaptive 1 to 120 Hz refresh rate, maintaining a 6.5-inch external display and an 8-inch internal canvas. Maximum peak brightness climbs from 2,600 nits on the previous model up to 3,000 nits on the new Ultra variant, though thermal throttling can reduce peak output under prolonged direct sunlight exposure. The primary upgrade on the internal screen is a new anti-reflective coating that drastically cuts down environmental glare without requiring maximum brightness. Furthermore, internal display resolution rises to 2,504 × 2,256 pixels, and a new Flex Titanium reinforcement structure makes the folding crease significantly less noticeable during frontal viewing.
Camera Upgrades: 50MP Ultra-Wide and Retained Optics
The rear camera array houses a 200-megapixel primary sensor with optical image stabilization, a new 50-megapixel ultra-wide sensor with an f/1.9 aperture, and a legacy 10-megapixel telephoto lens featuring a 3x optical zoom. According to technical evaluations, the ultra-wide upgrade delivers a 34 percent increase in light capture for low-light video alongside autofocus capabilities that enable macro photography. However, the 10-megapixel telephoto lens remains unchanged from the previous generation, drawing criticism from reviewers who note that competing ultra-tier flagships offer larger sensors and longer zoom capabilities.
Did you know? The physical thickness of the Galaxy Z Fold8 Ultra when opened is now constrained primarily by the physical dimensions of the standard USB-C port connector soldered onto the internal circuit board.
Performance and Software Ecosystem
Driven by the Qualcomm Snapdragon 8 Elite Gen 5 for Galaxy chipset paired with up to 16 GB of RAM and 1 TB of internal storage, the device handles intensive multitasking and local AI tasks smoothly.
Battery Capacity and Charging Speeds
Energy management receives its most substantial upgrade through a new battery yielding a 5,000 mAh capacity, up from 4,400 mAh in the prior model. Wired charging speeds also increase from 25W to 45W.
Frequently Asked Questions
Does the Galaxy Z Fold8 Ultra support the S Pen?
No, the device does not support the S Pen stylus, continuing the omission that began with the previous generation’s thinning of the chassis.
What is the water and dust resistance rating?
The device carries an IP48 rating, meaning it withstands fresh water immersion up to 1.5 meters for 30 minutes, but it lacks formal protection against fine dust particles smaller than 1 mm.
How much does the Galaxy Z Fold8 Ultra cost?
In the Czech market, pricing starts at over 50,000 crowns for the high-end variant.
How does the battery capacity compare to competitors?
While the Samsung offers 5,000 mAh, competing foldable models feature larger batteries.
