14. 2018 - iPhone XS and iPhone XS Max: The new iPhones, running the A12 Bionic processor, are 15 percent faster than the excellent A11 Bionic. The A11 Bionic chip could do 600 billion computations per second, whereas the new A12 Bionic can perform as many as 5 trillion computational operations per second, which also benefits the Face ID facial recognition feature. The 6.5-inch display on the iPhone XS Max is the largest ever in an iPhone. Apple also added the dual-SIM functionality, after many years of users demanding it, but in a different avatar—one of the SIM slots here would actually be a virtual SIM, also known as e-SIM. Nevertheless, these iPhones were significantly more expensive too—prices starting Rs99,900.
