With the new operating system by Apple having made way onto our Apple smartphones, it is very common for most people to think that there barely was a change introduced from the previous OS. True, there wasn’t another huge visual overhaul as presented in the previous year but certain features have been tweaked pretty nicely and the new features are great, too.
What includes in this upgrade is the new Health app, some works on the camera app with more editing features, a new predictive typing ability called QuickType, Family Sharing, iCloud Drive (being able to share all your music/documents and other files in general seamlessly throughout the rest of your Apple devices) where you can start work on one device and can continue working on another. It is important to note that this will only run alongside the new operating system for Mac called Yosemite (which is yet to be released later on this year). Wi-Fi calling and updates on Siri (now with Shazam integration) are also available on this new iOS.
Personally I do not recommend upgrading if you have an iPad 2 or an iPhone 4S and just stick to iOS 7, at least for the meanwhile since it’ll drain battery life quicker and performs faster than the devices can handle. Although with this being said, there have been individuals who have upgraded to the new operating system with their 4S and everything worked out well so if you’re curious on having the new software installed then go ahead and see for yourself, just make sure to not forget aboutbacking up beforehand (preferably through iTunes)!!!
