Can Apple 5S update the system of IOS 10? Remind me every day that I am impatient and online when I see that red dot.

Can be upgraded. Here is an introduction to the upgrade experience.

After upgrading the iPhone 5s from the previous iOS 9.3 to iOS 10, the fluency is similar to before, and there is no jam phenomenon (small card phenomenon), but QQ/ WeChat occasionally flashes back.

Seems to be better and faster than before:

Let's talk about other users' experiences (for reference only):

Netizens with old models said that the upgrade of iOS 10 was not smooth:

"It takes a few seconds to display the message directly on the white screen, and it is very slow to click any one in the settings. . . . "

"The drop-down notification bar and sliding notification card are more serious, and the others are ok."

"To be honest, it seems that iPhone 4 rose to iOS 7 that year."

Stability is definitely not as stable as the current version. There will be some minor problems when I first come out, and I will gradually improve.
