Sure thing, let’s crunch the numbers. A typical capacitive touch sensor pulls about 10 microamps for maybe a millisecond when you tap. That’s 10 µA × 0.001 s = 10 nanocoulombs of charge. One electron carries 1.6 × 10⁻¹⁹ coulombs, so 10 × 10⁻⁹ C ÷ 1.6 × 10⁻¹⁹ C/e ≈ 6.25 × 10¹⁰ electrons. In plain terms, each tap nudges roughly sixty‑two billion electrons. The phone’s battery is so big that this tap is essentially invisible to its overall power budget. That’s the math; no more over‑planning needed—just the raw numbers.
