Does iOS 8.1.1 have these feature or are they not present on my iPad Air?

Question

I have an iPad Air (wifi only) and iPhone 5s. I'm wondering if the following features exist in iOS 8.1.1 and maybe I've missed it?
#1- Raise to speak for Siri. I know there is "Hey Siri" but in order to use that it requires you to be a wall-hugger. Is that correct? I've read in a discussion board that you can hold down the home button to enable Siri, then bring it up to your ear. That seemed to work somewhat okay for me. I bought my first iPhone for the raise-to-speak feature...bought my 2nd iPhone for that reason. It's a necessary Accessibility feature for me.
#2- I know the Apple Wireless Keyboard always worked with my iPad Air and my iPhone 5s but wasn't always the same experience as when using a Mac. Meaning, the keyboard shortcuts that enabled me to be productive, weren't always enabled. For example, I can still use in Apple Mail, shift+command+D and that would send an e-mail I've drafted. I wish more of the same keyboard shortcuts I use on my MacBook Pro would be enabled with my iPad Air/iPhone 5s. But after updating, I noticed even more shortcuts were taken away. Things like fn+delete, command+delete or option+delete don't delete an entire word or sentence. I also can't use shortcuts anymore to highlight a sentence from my keyboard. Or at least, in Mail there seems to be some decent functionality. But in Safari when trying to send Apple feedback through these forms...no dice (on a consistent/reliable basis). Why not? Please bring that back. Being disabled is no fun. But these shortcuts helped me. Is it me, or have things gotten worse with this Apple accessory with iOS 8.1.1? Or, has anyone found a solution? Yes, I unpaired and re-paired the device. I also notice that while typing with the Apple Wireless Keyboard, it doesn't spell check as I type. That's no fun.
#3- Reliable searching in Spotlight. Keyword here is RELIABLE. I've seen a lot of folks on Twitter posting screenshots of searches in Spotlight in iOS 8.1.1 for even Apple apps (like Phone, Contacts, etc.) and nothing comes up for applications. I've had the same issue when it comes to searching for installed apps on my iOS devices. Why? I know the release notes for iOS 8.1.1 mentioned fixes for iPhone 4s and iPad AIr 2. But what about iPhone 5s and iPad Air? Where's the love? I've tried unchecking and rechecking the Spotlight options. That didn't help. Yes, reset all my settings. Didn't help. Right before iOS 8.1.1 was released, I had restored my devices.
#4- Reliable searching for event in the native Calendar app. Again, keyword here is RELIABLE. So a few times now, I have tried to search for (recent) or future events/appointments in the native Calendar app by tapping the search icon in the app. The result? Nothing was found when searching by that method. However, by going through the Calendar app (day-by-day) I was able to find the appointments/events I needed to. However, this experience was horrible and very tedious. And at first, I just heard about this issue from friends. And family members were asking me for help. Has anyone experienced this issue? Any workarounds?
#5- Battery drain issues since iOS 8.1.1 on both my iPad Air and iPhone 5s. For example, I was using Comcast/Xfinity's TV GO app to watch a movie I downloaded on my iPhone 5s. The device was in Airplane Mode and Location Services was off. The device ran very hot (even though it is quite cool in my apartment and outside, and it was not being plugged in). It went from a charge of 100% to the caution dialog box to recharge in just over 2 hours of viewing. Brightness setting was its lowest. Now, that experience is quite new to me. My battery was replaced by Apple about 4 months ago. I attempted to replicate the issue the following night with the same settings. It wasn't as bad but still a drain much faster than what I've seen before. Has anyone else experienced this type of drain? On my iPad Air, I've noticed a sharp decline in battery performance since updating to iOS 8.1.1 and I don't know why. And it's intermittent and frustrating. I use only Apple cords and adapters. I follow the instructions about Apple batteries and ways to optimize per the Apple website. Yet, I'm seeing a problem. Anyone else? Anyone have a fix?
#6- Is there any way to create location-based reminders on my iPad Air (wifi-only configuration)? I tried to make a location-based reminder and the native Reminders app wasn't having any of it. It would not allow me to do that.  Why not? I tether my iPhone to my iPad.
#7 - Is there any way to use Apple Maps on my iPad Air (wifi-only configuration) when tethering my iPhone 5s? It doesn't do turn-by-turn navigation. Why not? Any workarouds?
#8- Sooo.....you know on our iPhones it gives us the cellular data breakout? Is there any way to get a breakout of how the iPad Air  is using the Hotspot/cellular data? I ask because I know on Netflix website, there is an option to toggle playback settings. I switched it to "low" since I was going to be traveling. I noticed that when I tethered my iPhone to my MacBook Pro, the playback setting seemed to be at the low setting (based on cellular data usage from my iPhone). But when I tethered my iPhone 5s to my iPad Air, it ate up a whole lot of data. It's as if the Netflix app didn't adhere to change in setting. When I contacted Netflix, they said it was an issue with Apple. When I contacted Apple, they said it was an issue with Netflix. I was hoping to see some kind of cellular data usage report when we tether, so I can better help Apple or Netflix. Or...if you know of a way to get my Netflix to not eat up all my data, that would be great too.
I know this was a lot. But I appreciate any and all help. I'm interested in any other bugs you're seeing with the latest version of iOS 8.1.1. My apologies in advance if this has multiple spelling mistakes. Spellcheck and grammar check don't seem to want to work in this Safari session.

Answer 1

1. Unfortunately is was removed in iOS 8 .
2. Unfortunately being a mobile O.S. means not all shortcuts may work or have a counterpart there.
3.  I have no issues with Spotlight.  Make sure you have the categories ordered the way you want to see them. As sometimes the App results may be below other result categories where you need to scroll further down. You can change this in Settings->General->Spotlight and drag the categories to the order you want them.  For instance I have Apps at the top followed by Suggestions, and then Mail and then Contacts, and then everything else.
4.  Again no real issues for me there.
5. ---
6. ---
7. It should work. What happens when you try?
8. When the iPad connects to the iPhone hotspot, it treats it as a regular Wifi connection because that's all it is to it.  And since you cannot limit the usage from other devices on the iPhone, it just lets it use the Cell data as much as it wants.  You'll need to manually manage this.  A Cellular iPad will have the same Cell data management as an iPhone.  A Wifi only iPad will not, as it doesn't actually use Cell data itself, so nothing really to limit.
