According to famous Apple leaker Jon Processor, iPhone 13 Pro max might have 1TB of storage. Previously, iPhones used to have maximum storage of 512GB on their top model from iPhone Xs. But now thing are going to be changed. We might see new iPhone with 1TB of storage in 2022. But 1TB storage will be available in Pro models only.
We already saw Galaxy S10 Plus with 1TB storage back in 2019. But this is not common on android flagship too. There are only few phones with 1TB of storage. After Apple releases new iPhones with 1TB of storage then all android flagships will also include 1TB storage variant. When Apple removed charger from box, almost every brands poked them but now they are also doing same.
