If you own an iPhone 15 or iPhone 16 in Pakistan and you're deciding between a 20W and 30W charger, the honest answer is: the difference is smaller than most listings make it sound — but it's not zero.
iPhone 15 & 16 Fast Charging Ceiling
Both the iPhone 15 and 16 series support fast charging up to roughly 20-27W depending on the exact model, meaning a 30W charger doesn't unlock extra speed beyond what the phone itself can accept. Where the 30W charger helps is headroom — it stays cooler under load and leaves capacity for charging an iPad or MacBook Air later without buying a second charger.
Real Charge-Time Comparison (0-50%)
- 20W charger: approximately 30 minutes to 50% on iPhone 15/16
- 30W charger: approximately 27-29 minutes to 50% — a modest few-minute difference, not a dramatic one
When 30W Is Worth It
Go with 30W if you also own or plan to own an iPad, or if you want one charger that comfortably handles multiple Apple devices. If you only ever charge an iPhone 15 or 16, the genuine 20W charger is the more budget-efficient choice with no real speed penalty.

Frequently Asked Questions
Does a higher wattage charger damage the iPhone 15 or 16 battery?
No. iPhone's charging chip regulates power intake regardless of the charger's maximum wattage, so a 30W or even 65W charger won't overcharge or damage the battery.
Does the iPhone 15/16 require PD3.0 support?
Yes, for fastest charging speeds the charger should support USB Power Delivery (PD), which both genuine Apple and Anker GaN chargers do.
