iphone 5c 与6p的 user agent

如下：

5c: 
118.198.251.53 - - [01/Apr/2017:00:36:07 +0800] "GET /interface/home.do?city_id=28&article_type=you_hui_xin_xi&advertisement_type=airport HTTP/1.1" 200 126 
"http://weixinh5.touring.com.cn/" 
"Mozilla/5.0 (iPhone; CPU iPhone OS 9_3_5 like Mac OS X) 
AppleWebKit/601.1.46 (KHTML, like Gecko) Mobile/13G36 MicroMessenger/6.5.6 NetType/WIFI Language/zh_CN"


iphone 6p: 
111.196.162.232 - - [01/Apr/2017:00:41:16 +0800] "GET / HTTP/1.1" 200 534 
"-" 
"Mozilla/5.0 (iPhone; CPU iPhone OS 10_2_1 like Mac OS X) 
AppleWebKit/602.4.6 (KHTML, like Gecko) Mobile/14D27 MicroMessenger/6.5.6 NetType/WIFI Language/zh_CN"

可以看出，上面的iphone 5c 的版本是 9.3.5 ,

下面的iphone6p 的 ios版本是 10.2.1

但是光看user agent 看不出来。。。。
