iPhone imei check 13 has been officially presented by Apple and it brings a couple of changes and you need to decide if they're worth the additional money in comparison to previous models.First of all we get a fresh chipset called A15. Based on what Apple company claims, their newest products are 50% faster than their android competition. Which will be very impresive, but why is the unit so fast, well it comes right down to the number of cores utilized by the chipset. Previously the number was 4 but at this time it absolutely was risen to 6. The GPU also got one extra core, making the unit work even smoother.
