Charging Speed Guide — 15W to 240W Compared

Charging speed numbers are marketing — real-world results differ. OnePlus 13 at 100W charges 0-100% in 36 minutes. Motorola Edge 50 Pro at 125W charges in 24 minutes (smaller battery). iPhone at 30W takes 90 minutes. Xiaomi 15 Pro at 90W charges in 35 minutes. But heat during charging degrades batteries faster — we explain the longevity tradeoff at each charging speed tier.
