The best browser for iPhone depends on your needs. Safari is the fastest and most battery-efficient, with deep iOS integration—ideal for most users. Chrome is best if you use Google services, while Firefox offers good privacy and customization. For strong privacy, Brave and DuckDuckGo are top choices, blocking trackers and ads by default. Microsoft Edge is a solid pick for Windows users. Overall, Safari is best for most, but choose based on your ecosystem and privacy preferences.
