Is it necessary to buy a 128G mobile phone?

Preferred direction: necessary. Nowadays, smartphones are basically based on 64G capacity, which is equivalent to giving up the so-called 32G capacity. As for 16G, it's simply terrible. Think about installing a system, plus your own software application, then the capacity is even less. For an iPhone with 64G capacity, the capacity of the new machine is a little more than 50G after booting. In this case, look at the applications installed on the mobile phone, the photos/videos taken, and the cache that is being carried out anytime and anywhere, so I can't afford to hurt.

Moreover, some mobile phones themselves must reserve enough capacity space to upgrade the system, otherwise it will not be possible. If nothing else, just the photos and videos taken by users themselves, the unit of each photo is 3M, and the unit of high-definition video is 3M per second ... If your mobile phone itself has a capacity of 40-50g, but it has been used for a year or so, the basic remaining capacity does not exceed 10G, which is dangerous. In addition, if you think you are an environmentalist and don't pursue the so-called new machine release, the mobile phone will last for at least three years, then you will worry that the mainstream 64G capacity is not enough and have to buy a mobile phone with 128G capacity.
