    any particular reasons there is no low power mode for iPads? I would like that feature on iPads too, even if it would save less battery than on iPhones.

    Because the iPad battery life is to good for low power mode.

    Guessing:
    iPhone is a safety device that allows you to call home (wherever) in the event on an emergency. Having a little more power to cover the ability to call in an emergency can be critical.

    iPad is a device similar to iPhone with similar communication but at the end of the day not carried to cover emergencies in the way a phone is.

    With that said, no idea why other than to avoid suggesting it needs the feature because battery life is already very good.

    Yeah I totally agree. However it would still be nice to get an extra 1-2 hour when ur at 10-5%.

    Hehe. Do iPads actually also get an extra hour of battery life due to iOS 9 improvements, or is that only iPhones too?

    It's probably because many "switches you didn't even know about" involve cellular connectivity options, GPS, etc.

    My iPad mini 2 doesn't get the greatest battery life. Usually about 6-8 hours. That being said, my usage is primarily games and video, though. So that probably makes sense.

    Also the small amount of energy savings by slowing down services will make a large relative improvement for a small battery but will be more negligible on a large battery.

    Yeah, on iPad the screen is the big power draw for most use cases, and low power mode can't do much about that. Whereas on phone, the power draw is more balanced between processing and screen, with less battery to back it, so far more noticeable. essentially, the gains would be so small as to not be worth it.

    On an iPad, wouldn't low power mode just be airplane mode and make the thing useless? I agree with others that LPM on a phone can be crucial if you're away from a charger and need to make it last longer. The watch less so, but maybe you still need the time. I think the fact that the iPad batteries last for a LONG time and don't drain quite as quickly as the smaller devices makes LPM less of a necessity.

    I agree, to me it doesn't make any sense to have it on iPads.

    Wouldn't it just be a percentage? So in fact, in raw hours, the same savings on iPad would be more significant.

    Not exactly. Part of power save is to run the processor at a lower clock speed. Radio limits help too but are not all there is to the savings.

    yeah and it also disables background app refresh and mail fetch/push, so there are plenty of other things it can do outside of radio management.

    someone above said ipad has a large screen and low power mode can't do much about that. one of low power mode's features is to turn off the screen after just 30 seconds of inactivity (i believe this option is not available otherwise, at least on iphone). so there are things it can do...

    iOS 9 will let you auto lock in 30 seconds now.

    The goal is to increase standby on the iPhone, while on the iPad you'd want to gain more time to use your iPad.
