As we all know IOS 9.1 has released and most of the apple users are wondering if the should to shift to ios 9 or not well here i am today with some reasons that would help you make your decision

1.App swicther:

When your phone is awake and past the lock screen, and you double tap on the home button, iOS will kick up an app-switching interface so that you can toggle between apps, exit apps, etc.

Apple majorly redesigned the app switcher with iOS 7, but now, two years later, it's changing the app switcher again with iOS 9. Your apps will now appear as apps in a card stack that you can scroll through from left to right.

You can identify each card in the stack based on the app icon and name above it. To close an app, you still swipe up on the card. Now, however, you can also swipe multiple cards at the same time, using multiple fingers.

Handoff options appear at the the bottom of the app switcher, allowing you to quickly open an email, message, Safari page, etc, on another Apple device. The Handoff bar will show up when iOS detects your content is open on another Handoff-compatible device. From there, tap or slide the bar to the top of the screen to open the app.

Oh, here's a bonus tip: When you open a link or notification when using an app, you'll be brought to a new app to view that information in full. Now however you'll also see a new "Back to..." button at the top left of the just-opened app, giving you the opportunity to go back the app you were using.

2. Spotlight:

 

 

Spotlight has returned to the left of the main home screen, though it is still accessible as a pull down from any home screen. You'll immediately notice that Spotlight now works with a Siri-powered Proactive assistant, enabling you tap the mic symbol to audibly search and get suggestions based on how you use your phone.

Apple has added your recent contacts, app and location-based suggestions, and Apple News feed to Spotlight. Better still, Apple has opened Spotlight to third-party developers, meaning you'll soon be able to get Spotlight search results from, for instance, Netflix, Facebook, Google Calendar, etc.

3. Siri:

Siri has a more colourful interface now - and the personal assistant feature has been updated so it can do way more.

You can say, for instance, "Show me photos from Utah from last August", and Siri will know which photos to serve up. You can also ask Siri to remind you to grab your coffee off the roof of your car, because the personal assistant can look at your location information as well as determine when you're in a car.

Siri is "Proactive" now too. It can auto-play music when you plug in headphones, for instance - because the feature learns your habits and what you prefer over time. Siri can also retrieve an invite from Mail and auto-add it to your calendar, without needing you to open another app.

In other words: Siri has been given deeper integration with Apple's own apps. She can even predict which app you'll use next and provides app suggestions via the new Spotlight area on the left side of the home screen.

4. Low power mode:

 

 

There are several power-saving benefits in iOS 9. First of all, Apple has said you'll get an extra hour of battery life after the update due to tweaks. When your iPhone is face down or in your pocket, for instance, the screen will no longer glow when notifications arrive all working to save your battery life.

Also, under Settings, there is a new Battery section that gives you a detailed look at which apps are hogging up all your juice. There's a Low power mode as well, which you can use to reduce power consumption. The feature disables or reduces background app refresh, auto-downloads, mail fetch, and more (when enabled). You can turn it on at any point and are prompted to turn it on at the 20 and 10 per cent markers.
