Which is better for iPhone6 to run iOS9 or iOS 10?

IOS 10, of course. The iOS 10 version of Apple's mobile phone has added new functions and experiences:

1. For screen unlocking, "press the Home key to unlock" instead of sliding to unlock, and you can also unlock with your fingerprint (Settings-General-Accessibility -Home key-Turn on the "Touch Open" key).

2. When the screen is locked, swipe right to open "Today View" to view various Widget plug-ins. You can open the app to check the weather without unlocking it.

3. When the screen is locked, drop down the screen and open the Notification Center to view various notifications, such as SMS, QQ, WeChat, etc. , reply directly.

4. Slide up along the bottom of the screen to open the "Control Center", which is divided into two parts: flight mode, WiFi, Bluetooth, do not disturb mode and screen rotation lock on the left, brightness level, AirPlay, airdrop and night shift on the bottom, flashlight, timer, calculator and camera on the bottom, and AppleMusic on the left and right.

Mobile phones with 5.6S and above will have the function of invisible ink when they are upgraded to iOS 10 (Settings-Accessibility-Turn on "3D Touch").

6. Added the function of "family".
