3UF7931-0AA00-0 在智能手機領域，iPhone始終是無法超越的存在，A系列處理器的性能、iOS系統的流暢度，始終處于水準。
不過，蘋果手機其實也分好壞，倘若用戶有購機意向，有3款iPhone可以放心買，但也要牢記“兩不買”原則。
款：iPhone12
iPhone12是蘋果最新推出的旗艦機，也是蘋果5G手機，該機搭載A14仿生芯片，運行iOS14系統，性能表現在當下的智能手機市場堪稱。
不僅如此，iPhone12還通過外掛驍龍X55基帶，實現SA/NSA組網，這意味著未來該機不會因網絡問題而被淘汰。
在其他方面iPhone12也有明顯升級，例如蘋果升級為OLED屏，后置1200萬雙攝，前置1200萬單攝均支持夜間模式。
盡管iPhone12內置的2875mAh電池，續航能力較差，且不附贈充電器，但瑕不掩瑜，6299元的起售價，仍然讓iPhone12成為一款高性價比手機。
款：iPhone11 Pro
iPhone11 Pro雖然不支持5G網絡，但配置仍然很出色，該機搭載A13芯片，性能表現不輸驍龍888。
并且，iPhone11 Pro還可以升級為iOS14系統，與A13芯片協同作用下，其實際操作流暢度與iPhone12的差距微乎其微。
另外，iPhone11 Pro也搭載一塊OLED屏，前置1200萬單攝，但后置鏡頭為1200萬三攝，采用廣角+超廣角+長焦的鏡頭組合。
最值得一提的是，iPhone11 Pro內置一塊3969mAh電池，續航能力比iPhone12更強。
第三款：iPhoneXR
iPhone XR是一款2018年發布的老機型，時至今日，該機的優勢便是性價比。
iPhone XR在第三方商家手中的價格已經跌至3000元左右，但它的配置直到現在依然很能打。
iPhoneXR搭載的為A12仿生芯片，性能可以媲美驍龍865，而且iPhoneXR也支持升級為iOS 14系統，系統升級后該機的流暢度有進一步提升。
其他方面，iPhoneXR后置1200萬單攝，前置700萬單攝，內置2942mAh電池，整體配置也算可圈可點。
而所謂的“兩不買”原則：其一是，比A12芯片還老的機型堅決不買；其二是，非劉海屏外觀的堅決不買。
一般來說，一顆處理器的使用壽命在5年左右，倘若為機主留出2年使用時間，搭載A12芯片的iPhone XS便是守門員。因此，iPhoneXS之前發布的機型，消費者不要買。
而非劉海屏的iPhone，即便配置依然能打，但外觀設計卻早已落后時代，難以為用戶提供更好的使用體驗，因此非劉海屏的iPhone也不建議入手。
