Apple iOS 5 Review

Safari, too, has gotten a UI refresh on the iPad side of things. We finally get tabbed browsing, which really makes life easy when you’re browsing - it was the single most useful feature that Honeycomb had over iOS last year. The tab bar is located underneath the URL bar, and the active tab has an “x” on the left side to close. There’s not too much more to say here other than that it’s well integrated, and being able to see all the open tabs at once really makes the multipage browsing experience quicker and more seamless. It’s a seemingly minor detail, but taking out the extra two screen presses really speeds everything up. It almost makes me wonder why Apple took so long to implement it on the iPad.
Reading List ties in very well with the other new browser feature, Reader. Reader basically takes a webpage and renders it in the most readable way possible, stripping all formatting and displaying the text and image content alone. Think of it like iBooks, except for webpages. Getting to it is pretty easy - just wait for your page to load, then hit the Reader button in the URL bar. The cool thing is that for multipage articles like the ones on AnandTech, it’ll load the next page automatically as you finish reading the previous page. It’s a relatively minor feature, but if you read a ton of longer (*cough* AnandTech) articles on your iPad or iPhone, Reader ends up being really, really useful.
Safari Performance Improvements
There's been a trend among mobile browsers recently, and that trend is increasingly fast JavaScript performance. Both iOS and Android have been trading blows for the JavaScript performance crown, and iOS 5 includes the latest set of improvements from Apple's side.
The brief outline version of this story is that each successive release of iOS has improved JavaScript performance. First, iOS 4.3 brought desktop Safari's Nitro JavaScript engine with JIT (Just In Time compilation) to MobileSafari in iOS, which gave a substantial boost to its performance in synthetics and other tests. The latest improvements in iOS are thanks in part to an update which brings MobileSafari back up to parity with Safari 5.1's codebase on the desktop side. For a while now we've been keeping track of iOS performance in SunSpider 0.9 and RightWare's browsermark, and now SunSpider 0.9.1 as well.
Sunspider 0.9.1 we haven't been keeping track of for very long, so we don't have as many results yet, but that will change in time. The other two graphs really tell the story of how Mobile Safari has seen steady improvements to JavaScript performance over a short history going back to iOS 4.0. Again, the 4.3 added Nitro with JIT, and 5.0 updates Nitro to the absolute bleeding edge version of the codebase, same as the desktop Safari. That said, I don't expect things to speed up much beyond this, and though I'm not showing Android results (since the context of this story is all about iOS), I expect Ice Cream Sandwich to bring Android right back up to parity with Mobile Safari's scores on similar hardware.

Have you guys noticed any weird issues with WiFi sync? It seems that whenever I would unplug my phone, iTunes would start freaking out because it couldn't find the phone. That's pretty obvious why... it's no longer on the network since iOS only keeps WiFi alive while plugged in. It would constantly pop up an error about being unable to find my iPhone or iPad.Not to mention leaving "Open iTunes when this device is connected" would cause iTunes to constantly open up... even when closed. Turning this off caused my device to enter some weird limbo state with iTunes. Plugging it in gave me an error, "Another iPhone has sync'd with this computer." The only options were to restore or setup as a new iPhone. A little Googling revealed that the only option was to hit setup as new iPhone and quickly unplug the cable.
It worked, but now my device just comes up as "Apple iPhone" instead of how it used to.
I really don't like iTunes.

I just straight up cannot get it to function with my iPad 2 and MBP. I have tried pretty much everything I can think of without any luck. Not that it bothers me that much, I would just like to have it working to simplify the syncing of the two.name99 - Thursday, October 20, 2011 - link
There are two things you might want to try.(a) Shame on Apple for not making this clear, but you have to go to iTunes and, while the phone is plugged in, toggle the "Sync with this phone over WiFi" checkbox. It is not set by default, and when you try to sync on your phone, the phone gives a useless error message rather than telling you this setting needs to be toggled.
(b) You have to ensure that your phone in on the correct wifi network. If you have a modern Airport base station and have a guest network setup, you must ensure that the phone is NOT on the guest network --- best is to tell the phone to forget the guest network. This makes perfect sense --- the whole point of the guest network is to contact the outside world, without allowing you to contact machines on the local LAN.

Guys, I think devoting graphs to gains of 0.1s is... mmmm.... we French say "sodomozing flies". I think the coclusion is 1- don't do graphs for irrelevant sutff (especially, not lots and lots fo thm) 2- a 0.1s improvement is not forth more than a "slightly speedier" comment in passing, and 3- those times are so low to start with, lobel them "very good", and talk about some interesting ?I know benchmarking is fun and all, but we're well past the point of irrelevance.

In depths of northern England we go for sheep - but I think that is a lifestyle choice rather than pithy phrase describing graphs!!Samoht - Tuesday, October 18, 2011 - link
interesting.. in danish it's called flyf**king. Maybe the translation from french to danish didn't carry all the way over ? Or maybe we do not need the specifics;-)Kristian Vättö - Tuesday, October 18, 2011 - link
What they show is that there is no difference, which is kind of their point.grkhetan - Tuesday, October 18, 2011 - link
I didn't know AnandTech did software reviews... I have been coming here every day since the last 3-4 days to see the iPhone 4S review, but finally I see here is an iOS5 review. But even this was high quality as your hardware reviews are -- I love how you go into detail of everything and don't cut back on prose. With hardware your reviews are unmatched in the industry considering your technical depth.Anyway, nice review and great coverage. However, when is the iPhone 4S hardware review coming out?

Go read an iPhone 4 hardware review; it's basically the same thing. The only (physical) changes are minute and you'll get different bar charts.
