Questions about this item

How do I insert the dual Nano SIM cards and the microSDXC card without damaging the tray?

Power off the Redmi 15C, locate the tray on the left edge, use the ejector pin to pop it out, seat both Nano SIMs with the gold contacts facing down and the microSDXC card in the dedicated slot, then slide the tray back until it clicks.

Which component will need replacement first during the phone's lifespan?

The sealed 6000 mAh battery is the only part that chemically ages; after several hundred charge cycles its runtime will drop noticeably and a professional battery swap will be required.

What thermal limit appears first when I game continuously on the Helio G81 Ultra at 120 Hz?

Sustained load triggers the processor's thermal throttle, lowering the 2.0 GHz core clocks and Mali-G52 MC2 GPU frequency to keep the chassis temperature within safe limits.
