iPhone 15 Gets USB-C But No Major Battery or Charging Upgrades

iPhone 15 battery life stays the same as iPhone 14 despite weight reduction and new processor.
Charging speed remains disappointing - still over 1 hour for a full charge. No improvement over iPhone 14.
Finally switches to USB-C port, but still limited to 20W charging like last year's iPhones.
Still lags behind fastest charging Android phones like OnePlus 11 (100W) and Galaxy S23 Ultra (45W).
Lack of major battery life or charging gains could disappoint upgraders, but USB-C is a nice convenience improvement.
