The Apple iPhone 13 Pro Max’s battery is a lot bigger than the 13 Pro with a difference is over 1200 mAh. All praise to the iPhone Pro max for having the best battery life ever for an iPhone. But the regular Pro is more middle of the row. It still is still an improvement over last year. New iPhones don’t come with a charger. But if you use Apple’s 20W adapter, the iPhone 13 Pro Max supports fast charging (27W, unofficial rating), 50% in 30 min (advertised).
