I don’t know which “new phone” and which “previous models” you mean. Tell me the phone models (or let me look them up) and I’ll compare charging times precisely.

While you tell me, here’s a concise checklist and method I’ll use to compare charging times so you know what to expect and what I’ll check:

What I need to compare

• Phone model names (new model + specific previous models).
• Charger spec used for each (included charger wattage and USB standard, e.g., 20 W USB‑PD, 65 W proprietary, MagSafe 15 W, etc.).
• Battery capacity (mAh) for each model.
• Charging protocols supported (USB‑PD, PPS, Qualcomm Quick Charge, proprietary fast‑charge).
• Charging curve / charging speed to 50% and to 100% (manufacturers often publish 0→50% and 0→100% times).
• Whether times are with the screen off/airplane mode or measured in real‑world use.
• Any temperature/thermal throttling notes or battery‑health related limits (some phones slow charging near 100% to protect battery).

How I’ll present the comparison

• Side‑by‑side table (charger wattage, battery size, protocol, 0→50% and 0→100% times).
• Normalized metric: minutes per 10% or minutes to add 1000 mAh (helps compare across different battery sizes).
• Notes about real‑world factors (background apps, temperature, cable quality, whether fast charging requires the OEM charger).
• If manufacturer publishes only partial numbers, I’ll cite those sources and note real‑world test results from reviewers if available.

Quick examples of typical outcomes (illustrative only)

• If new phone supports 65 W charging vs previous models at 30 W, expect much faster 0→50% (often ~15–25 minutes vs ~30–40 minutes) and 0→100% (often 35–50 minutes vs 60–90 minutes), but actual 0→100% depends on charging curve.
• Higher wattage benefits larger batteries more in absolute minutes saved, but charging slows above ~80–90% to protect battery—so 0→80% is where most gains show.
• Wireless charging is usually significantly slower than wired; even “fast” wireless (e.g., 15–50 W variants) often lags wired 65+ W charging.

If you want, give me the exact model names (or say “look them up for me”) and I’ll fetch manufacturer specs and recent reviewer tests and give a precise, cited comparison.
