Dont
I (thought I) had my credentials to MacRumors on one OS on my computer. And I rebooted just for you when I saw this thread.
Well, I dont have the credentials for my previous account so heres a new one, but anyway.
Stay. On. iOS. Six.
iOS 6 was a pinnacle of speed and stability. My device was fast, fast, fast. That was my first iOS device and I was **in love**.
Then I upgraded to iOS 7 and I lost all of that (not to mention the more attractive design). Then I upgraded to iOS 7.1 and it became a bit better, but still less stable than iOS 6 and far more slower. My god.
iOS 8 is slower than 7.1 even. iOS 8.1 is faster than 8 but slower than 7.1 still.
Its crazy. Every bit of interface lags. Everything is laggy.
Lets quote Tim Cook on Android tablets:
I think if I bought [an Android tablet] and used it, and I thought that was a tablet experience, Im not sure I would ever buy another tablet, the responsiveness isnt there. The basic touch is really off.
Well, he has put the finger right on how I feel about my iPad after iOS 6.
Also iOS 8 is a pretty weak package, iPad 4 or not. I just bought an iPad mini 2, with an A7, the processor Apple had in mind when designing iOS 7. Well, its faster than my iPad 4, but its still very slow. You cant just throw money to solve iOS 8s problem. The top of the line iOS device in raw computing terms, the iPad Air 2, has a slower interface than your iPad 4 with iOS 6. ⁽¹⁾
I thought maybe the problem was with my iPad 4. Well, my iPad mini 2 purchase disclaims that. The only hypothesis I got left is that people dont consciously notice responsiveness (though its really, really important), which would also be why Apple permitted itself to not care nearly as much about it with iOS 7.
Lets go back to iOS 8, its not just speed (well, the lack thereof), there are an unbearable number of BUGS. Its all buggy. I often must type ten times and wait as many seconds (this is not an exaggeration!) in a textarea to be able to select the text, the text cursor isnt blinking anymore and the select popup wont be touchable. iOS 8 users who type on forums must know what I mean, its really sad. Editing text on iPad is super-painful.
Its a dark period for Apple software. Hope they sort themselves out this iOS year. If my first iOS device had been on iOS 7/8, I would think way, way less of Apple (kind of incredible how good the UX was with iOS 6, in a freakin' complete operating system). Its a really big f up.
Really infuriating stuff, all of this.
(First time I really post my thought on this, as I flabbergastedly saw pretty much noone complain about this, until I stumbled upon this thread.)
(1): To be clear I did not test the iPad Air 2. But its logical than it will not be up to par with an iPad with iOS 6, just like the mini 2 is. This is really a software problem.
P.S. I did restore it to factory settings to test if this would make things faster. Nope. Well, a little bit faster, but it has nothing to do with the blazing speed I continuously experienced with iOS 6.
