256GB AT&T-locked smartphone

The Samsung Galaxy S23 Ultra arrives new in Phantom Black with 256GB of storage and 8GB of RAM. It is sold as a single-SIM device locked to the AT&T network and intended for prepaid or no-contract use. The handset includes an integrated S Pen with Bluetooth, accelerometer and gyro for remote control and note-taking. Buyers who need an unlocked model or dual-SIM capability should look elsewhere.

Dynamic AMOLED 2X 120Hz display

A 6.8-inch Dynamic AMOLED 2X panel runs at 120Hz and supports HDR10+ with 1200 nits typical high-brightness mode and 1750 nits peak brightness. The screen measures 114.7 cm² and covers roughly 89.9% of the front surface. The glass front and back are protected by Gorilla Glass Victus 2 within an aluminum frame. No thermals, fan noise or power-draw figures are provided for normal use.

Grade C cosmetic condition

This unit is graded C, meaning the body may show dents, cracks, chips or scuffs and the display may have scratches or dark spots. The device is functionally new but cosmetically imperfect. Dimensions are 163.4 x 78.1 x 8.9 mm and weight is 234 g. Shoppers who require a pristine appearance should consider a higher-grade unit.

Questions about this item

How do I install the embedded S Pen and what step do people miss?

The S Pen slides into the bottom silo until it clicks; the step people miss is pairing it via Bluetooth in Settings before using air-gesture features.

What maintenance will the 5000 mAh battery need later?

After roughly 500 full cycles the 5000 mAh battery may hold noticeably less charge; a professional replacement restores original runtime.

What limit appears first during sustained 120 Hz gaming on the 6.8 inch display?

Thermal throttling of the Snapdragon 8 Gen 2 for Galaxy chipset typically kicks in before the 5000 mAh battery runs low.
