The Cortex-A53 is an in-order, 64-bit core known for its excellent power efficiency. On a 28nm HPC+ process, the SL8541E balances thermal output and battery drain. A smartwatch has a tiny battery (usually 400mAh to 700mAh). Running a high-clocked A73 or A75 core would generate excessive heat and deplete the battery in hours. The 1.2 GHz clock ensures that typical tasks (receiving notifications, tracking steps, making calls) run smoothly without overheating the small chassis.
