    Oddly, my battery life was terrible the day I installed iOS 9. Now, I've noticed a big improvement in battery life.

    That is normal Major iOS updates regenerate the spotlight database which takes a hit on battery life.
    Always better to wait a few days before trying battery duration checks.

    CPU is throttled a bit and display auto-lock/timeout is much quicker.

    Just like the lessons from iPhone were brought back to improve the Mac, the lessons from Watch are now going to improve iOS. It's a nice cycle.

    The funny thing is that those things Apple supposedly copied from Android... Already existed in the APPLE JAILBREAKS or various desktops, including OSX... Before they even got to Android.

     

    Not, only that but the Android implementation was often more half assed than the one they were copying from in their first few iterations!

     

    So much selective memory from Androitites...

    They have had it for a while. However, the implementation is different. On android, your screen goes to a very limited number of apps the display is black and white.  Apple's does more in the background, so it really depends on your preference. 

    Apple's implementation is a lot classier and smoother. I don't even notice a difference when it's on.

    Sammy's if I remember correctly turns the screen black and white and has limited functions like calling and texting.

    And if you still need more power, there's always Mophie.

    Your traffic app is not actually running for hours in background since they are limited to few minutes then put to suspension state.

    I see lots of people killing/clearing their "open" apps thinking that it will improve the battery life and performance. That's not how iOS works.
    ...

    Actually, there are ways of extending the background execution time beyond 10mins for apps that use specific features like background location, VoIP, music streaming/playback. Very simple ways, in fact. It's up to the developer to be responsible with the CPU usage otherwise the thread will be killed by iOS. But iOS will not forcefully kill a light-running thread of an app that has background running justified by supporting the previously-mentioned features it has. Some apps also utilize silent notifications which will wake the app in the background to do its thing. But if you kill the app, silent notifications won't wake it anymore.

    Tl;dr; version: it's not a myth and killing open apps actually can help with battery life.

    I have IOS 9 on my 6 and my battery screen does not look like this. I only have last 24 hours and last 7 days, not last 3 hours as shown. Do I have a different version?

    I am confused about what happened here. :???:

    I saw the "last 3 hours" header immediately after installing iOS 9. After a day, it is no longer shown.

    As a developer, I second this.

    Can the face-down devices feature be overridden?  I use my phone as my alarm clock (using an app, not the built-in clock) and play music at night.  It disabled both of those things last night, and I was late to work this morning.
