第一、拍照性能疯狂升级
由于三星、LG、索尼等对拍照的努力钻研，iPhone6s的拍照性能竟开始落后安卓旗舰，这让苹果不能接受，所以iPhone7的最大升级便来自摄像头。iPhone7采用了1200万像素摄像头，并且支持光学防抖技术，配备f/1.8大光圈，6镜组镜头，蓝宝石玻璃，支持LivePhoto。
iPhone7 Plus则配备了传说中的双摄像头，一个广角镜头（f/1.8）、一个长焦镜头（f/2.8），均为1200万像素，通过两个摄像头间的无缝切换，可以实现2倍光学变焦和10倍的数码变焦，并且双摄像头均支持光学防抖。
iPhone7/7 Plus的前置摄像头均升级到700万像素，支持LivePhoto、支持拍摄广色域照片。
第二、IP67防水防尘
iPhone7/iPhone7 Plus终于成为了苹果首款防水防尘的手机，可惜的是防水级别不高，可以防御水溅，比如打翻的水杯、四溅的水花等，但如果想带着iPhone7洗澡或者游泳还是有些风险。苹果的防水防尘是为了提高手机抗风险能力，大部分人手机进水的情况均非故意，所以防水溅在一般情况下是足够应付的了。
第三、全新配色
配色才是第一生产力！近来的每代iPhone都新增一款配色，iPhone7也不例外，本次iPhone新增了亮黑色和黑色两种配色，深空灰被取消，银色、金色和玫瑰金还在。其中最具人气的当属亮黑色，亮黑色表面高光处理，采用阳极氧化及抛光技术，与其他金属机身的手机显得截然不同。相信上市之后会引发抢购狂潮，不过亮光黑配色仅存在于128GB版和256GB版上，32GB版没有这个配色。
第四、A10四核处理器
苹果的移动处理器在性能上一骑绝尘，这次发布的A10处理器直接升级为4核（大小核），性能相比A9在效率上提升40%，在运行速度上提升了20%，并且功耗进一步降低。iPhone7相比iPhone6s可多续航两小时，iPhone7 Plus相比iPhone6s Plus可多续航一个小时。
第五、立体声扬声器
iPhone7/7 Plus在声音上做的文章不仅仅是取消了3.5mm耳机接口，同时也为消费者提供了立体声扬声器，iPhone7的上部和下部都有扬声器，音频输出是iPhone 6s的2倍，动态范围也有所提升。iPhone7随机附赠了Lightning接头的EarPods耳机。当然，如果你还想继续使用旧耳机，也可以使用随机附赠的3.5毫米耳机插孔转换器。
第六、存储容量空间提升
正如此前曝光的一样，苹果终于升级了手机存储空间，不再有扣扣索索捉襟见肘的16GB，最低32GB起，然后为128GB和256GB，而此前传闻可以瞬间塞满存储空间的60帧4K视频录制并没有在iPhone7上出现，所以今年购机可以少些纠结，128GB很难存满，32GB对于普通人基本够用，何况还有很便宜的iCloud云存储空间。
