The reason for the exclusion of the iPhone 12 series is apparently its launch. The 2020 flagship lineup was finally unveiled on October 13, however, it was only received by a relatively small number of users. Thus, AnTuTu decided to exclude it from its list. The iOS devices ranked in their October list is based on the user reviews and its overall reception that have been received last month.
Looking at the list, the iPad Pro (12.9 inch model) took the top spot with 99.48 percent 5 star ratings from users. The iPhone SE came in second with 98.07 percent while the iPad Pro (9.7 inch) and iPad Pro 2 (10.5 inch) came in third and fourth with 98.06 and 97.3 percent respectively. The only other iPhone that made it to the top 5 in the list is the 5 year old iPhone 6S Plus with a 97.25 percent 5 star ratings.
This list is indicative of how popular Apple devices remain despite their age. Other notable older models the iPhone 7 (96.03 percent), the base iPhone 6S (96.82 percent, and a couple of other iPad models as well. We might see the iPhone 12 lineup make an appearance in the November 2020 list. So stay tuned for more updates.
