Dieter just told us about Crackberry Kevin’s uber-frustrating experiences trying to pit the iPhone 3G and Blackberry Bold head to head in the browser war to end all browser wars. But — silver lining — for iPhone users, not only did we snag bragging rights, but a handy tip as well!
Unlike the Blackberry Bold, the iPhone defaults to having Javascript enabled. As anyone who’s waited — and waited — for an overstuffed Facebook profile to load already knows, Javascript can be heavy lifting for a browser. For WebApps, it’s a necessary sacrifice, but if all you want is casual browsing, you can turn Javascript off and send MobileSafari into turbo mode.
Here’s how:
From the iPhone home screen, tap Settings. Scroll down and tap the Safari button. Under Security, slide Javascript to Off.
There you go, you’ve just switched to light, clean HTML and CSS mode (still technically “just the internet” — unless you’re in the UK…). In Crackberry.com’s tests, it made a big difference on some sites. Let us know how it works for you!
Here’s the backstory to what you’re looking at, above: Mobile Computing posted up a video showing that the iPhone 3G obliterated the BlackBerry Bold in a download & render test of web browsers (We just covered this, oh, hours ago). Fun stuff, except as our friends at CrackBerry noted (and MC added too) - it wasn’t a fair fight. The Bold probably wasn’t actually using WiFi and also most of the Bolds out there have pre-release ROMS on them, so the finals might be a stitch faster.
So a loyal CB reader pitched in and posted a video of the Bold loading the same page again, but this time actually using WiFi, it came in a little bit faster.
At TiPb, though, we figured it still looked slow. But since the Bold probably had a pre-release OS on it, we figured we’d hobble the iPhone 3G as well. So above, Loyal Moderator Bad Ash pits the BlackBerry Bold on WiFi against the iPhone 3G on EDGE.
Yeah, it’s closer, but we’re still ahead by 4 seconds or so. Tie the iPhone 3G’s WiFi hand behind its back, fine. Tie it’s 3G hand back there too, fine. The iPhone 3G still seems to win out — and we look forward to being able to say that about the final Bold ROM too. Hey — you guys still have (slightly) more reliable push email, so there’s that.
Between the time you click a link and a web page finishes loading on your iPhone, there are many factors that ultimately decide just how fast that process will be, including connection speed (2.5 G EDGE/3G HSDPA/WiFi) CPU speed, and rendering engine. Like desktop Safari, Mobile Safari uses Apple’s open source WebKit rendering engine, and it seems like for 2.0, WebKit has gotten its turbo on, especially in handling Javascript. Says Daring Fireball:
For all the hubbub regarding the new App Store, most “iPhone software” runs in the web browser. But improvements in WebKit performance often help native iPhone app performance, too — a slew of my favorite native iPhone apps have built-in WebKit browsers (e.g., NetNewsWire, Twitterrific, Instapaper, and Cocktails). When WebKit performance improves, any app that uses WebKit improves, and WebKit improved a lot between iPhone 1.1.4 and 2.0.0
The original iPhone on 1.0 was already fast compared to some 3G phones because of the speed of its CPU and the optimization of its WebKit engine. Now it’s getting silly fast. And I don’t think we’ve even gotten the extra nitro from the new Safari 4 and SquirelFish tech yet either?
Just prior to the original iPhone’s release, AT&T’s operation “Fine Edge” brought faster, stronger, better 2.5 / 2.75G speed to the GSM masses. This year, in a strangely reminiscent move, reports are coming in that AT&T is showing their 3G HSPA network the same type of love:
For the past few months we’ve been seeing average download speeds between 500 - 800 kbps with a spike here and there. This morning’s tests however, are yielding between 1400 - 1500 kbps.
Gee, could another iPhone release be on the horizon?
Despite the iPhone’s Mobile Safari browser rendering pages faster on Edge than many “competing” devices can on lesser browsers with faster connections, the race to speed the feeds continues, and AT&T has not only taken an early lead, but is positively driving towards the 3G finish-line.
Amazing what a little technology (and a billion dollars) can do.
But wait, there’s more: AT&T intends to increase its network speed by a factor of 5 by next year. That’s a quintuple screamer right there, never mind the upcoming switch to 4G LTE speeds…
The iPhone Blog merged with the Phone different site in May of 2008. Both sites were founded on a premise that comes one from one of Apple's old slogans: Think different. The iPhone Blog: for people who dare to phone different.
