The first photo in my iPhone 7 photo album, April 2, 2017, was a cat in the backyard of London, next door.
It means that my mobile phone has been bought for almost two and a half years. It feels as smooth as the new one. It has enough batteries (85% of the original power) and more than half of the storage. So there’s no possibility of changing the phone (the first iPhone 6 of the phone was broken three times, otherwise it might never have been changed).
For many people, the launch of the iPhone is "your mobile phone should be replaced", but for me, it’s just "what can I do to change the essence of any life if the mobile phone can be so powerful now?"
Btw. A while ago, I saw a statistic that the iPhone 7 is the largest mobile phone in the world. Yes.
