    Currently running beta 11 on my new iPad Pro 10.5". Battery life sucks so far. Slight improvement from beta 2 but still overall sucks. I've never run iOS 10 on it cause I immediately restored from backup which was beta iOS 11, so I have no experience with the iPad Pro and a release candidate OS. Is there any possibility that 120hz refresh rate consumes a significant amount of more battery power than 60hz?

    Even though 120Hz would consume battery more than 60Hz, the difference would be minuscule unless all yo do is swipe around in the GUI nonstop until battery drains. For normal usage 120Hz will not make any difference. I definitely believe that battery life is more dependent on your settings in background app refresh, wifi/bluetooth on/off, brightness etc.

    I'm running 10.3.2 on my iPad Pro 10.5" and so far the battery life has been great even with the smart keyboard attached. It is possible that the 120Hz refresh rate will use more battery power but I can't tell either way.

    Isn’t promotion a function of the iPad Pro and so in both iOS 10 and 11?

    Either way it doesn’t run at 120Hz all the time so it’s unlikely to be the cause.

    Battery drain is caused by screen brightness,Bluetooth,wifi use,and location services. 60 or 120 Hz refresh rate can't do more than about 3-6 percent difference,turning off location services and Bluetooth would save a lot more.

    Bluetooth, when not in use uses so little it is not worth turning off. Screen backlighting is the number one user with the CPU coming in second for battery use.

    Yes,but with photo frames,watches,loudspeakers and so on with Bluetooth,and most of them set to connect automatically,it's easier to prevent it by turning off Bluetooth on the device if not in use.

    Even so the amount of power used by BT is small compared to the backlighting and CPU. All of my devices have BT turned on since the day I bought them and the power use is not an issue. Unless the BT is actually being used it goes into standby. It is not like BT we used years ago.

    I know,but if battery drain is a big issue,then every unnecessary thing should be turned off. However,on a normal day for me,my phone still got around 30-60 percent battery left,so for me,it's not a big issue.
