Questions about this item

How do I insert the Nano-SIM and pair the Bluetooth S Pen on this Galaxy S23 Ultra?

Use the ejection pin to open the tray, seat the Nano-SIM with the gold contacts down, then slide the S Pen into its silo; the phone detects it automatically and prompts the Bluetooth pairing wizard.

Which components on this Galaxy S23 Ultra are most likely to need replacement after heavy daily use?

The 5000 mAh battery will degrade first; the USB-C port and the S Pen tip are the next common wear items.

What thermal limit appears first when the Snapdragon 8 Gen 2 is pushed continuously at 120 Hz on the 6.8 inch display?

Sustained load triggers CPU and GPU throttling to keep the vapor-chamber temperature below its safety ceiling, reducing frame rates before the 1750 nits peak brightness can be maintained.
