The iPhone 4s and iPod Touch 5 have the same processor, it should run the same on both of them.I think it is. I am running iOS Beta 4 on my iPod touch and Beta 4 on my
iPhone 5 and it doesn't have that many bugs. I have been using it as a "daily
driver" and it works almost exactly as 7.1.1 did, the animations are faster so it
feels faster. The speed and performance depends on what device you have,
the iPhone 4s and iPad 2 run iOS 8 with lag, so I went back to iOS 7, but if you
have an iPhone 5 or higher, iPod touch 5, iPad 3 or higher, I would recommend
using it. I have tested iOS 8 on iPod touch 5, iPad 2 and 3 and 4, iPhone 4s and
5. They all worked pretty good. Some apps do crash, but not as much as they
did in beta 1. So if you decide to update, make sure to backup your iDevice
through iTunes before updating, so if something goes wrong you can go back .
(remember iOS 8 Backups do not work on iOS 7)
Best of luck,
Some of the new apparent bugs in Beta 4 are a bit troubling. I tried to create a new contact out of a new SMS message (from a new number obviously) and that failed miserably (the Done button wasn't there despite reboots/etc)Gosh NO.
I can't say any beta has improved over the previous for me. At least in beta 3 I regained access to the LTE network... But I had to reboot my iPhone 5 at least 5 times today with beta 4, just doing casual stuff and a little bit of development.
I totally get the same feeling. The Music App hasn't changed a bit in iOS 8 if we compare it to iOS 7, and yet it presents so many bugs and crashes. Even as a developer, I don't understand this.It blows my mind there are this many bugs even in established apps (native ones).
That's how it is after an update. You have to give the phone a few hours or days because there are some background stuff going on, like indexing spotlight and what not. Ios beta 4 is much more stable.I've never dropped from 100% to 89% battery in 25 minutes... this happened with beta 4...
the first 25 minutes were terrible it felt like a really old phone, on how slow the animations worked... I just couldn't believe how unpolished it is for a "beta 4" which is supposedly close to final version (5S)
went back to 7.1.2 and my jailbreak thanks but no thanks... this is not ready for prime time at all.
left my phone unplugged last night at 100% it is still at 100%
