Performance

Well let’s just say that Froyo is really fast, at least on paper. The new JIT compiler for the Dalvik VM is about 2-5x faster than the one used in Éclair (v2.1) and CPU intensive code is executed much more efficiently. Memory management has also been improved and multitasking seems snappier. Basically, Froyo will not make your device run obscenely faster than before, but it will speed things up to the point where you’ll definitely notice a difference. That being said, Froyo still lacks the overall smoothness and responsiveness of Apple's iOS. It still suffers from sporadic stuttering and choppy scrolling. Animations are generally smooth, but are still prone to occasional slowdowns (something that Apple has actually introduced with iOS4). The issue is acutely exacerbated while using Live Wallpapers; that’s when phone feels really sluggish.

Froyo Performance Tests
Android Revision Linpack (MFLOPS) BenchmarkPi (ms - lower is better) SunSpider (ms - lower is better)
Nexus One (Android 2.2) 36.864 1165 5702
Nexus One (Android 2.1) 6.994 2820 14564

In terms of raw numbers, Froyo’s performance is hard to beat. The numbers speak for themselves; the Linpack benchmark shows a whopping 427% improvement from v2.1, while the BenchmarkPi and Sunspider tests post approximately a 140 - 150% boost in performance. Looks like the JIT compiler packs some serious under-the-hood optimizations. However, under normal usage scenarios, the performance delta isn’t as noticeable as the numbers lead us to believe. While things are quite snappy overall, don’t expect your phone to boot in 10 seconds.

    This is why I hate apps in general. For some of the most basic and common sense stuff, it requires apps to do them. Why? Is it so hard to type a number and have a list come up? Seriously?

    I need to apply to better design the UI. Personally, it's horrible and outdated.

    Ummm my 1.5 Magic Sense UI has that? Or am I mixing this up with something else. Reply

    While I'm not keen on Android (disclaimer: I've only had light hands-on time with a Droid while I configured it to work with a client's Exchange 2007 server), I have to admit that the Android WiFi hotspot feature makes me envious.
    Do the various and sundry carriers ding you with a tethering fee to cover this (AT&T, I'm specifically looking at you)?
    How does battery life fare when you're using your phone as a hotspot?

    Please add performance comparison to iPhone3GS, iPhone4 and iPad. Reply

    right, I'm sure they are going to get right on comparing a pre-release OS to unreleased hardware. Reply

    I'm in the market for a new smartphone but I need to be able to encrypt email on the device. I'd much rather buy an Android phone than an iPhone but I can't find any information on how to do this. This is available on the iPhone 3GS/4 with iOS4. Any suggestions for something similar on Android? As far as I know there aren't any Android devices with hardware encryption but I'd be content to try a software solution. Reply

    I was hoping that the official Froyo release would have a native media player that could play divx etc......as this has been one of the big thing lacking imho.....that is the only thing I am soooo missing on this otherwise brilliant HTC Desire.

    Also a more simplistic manner of controlling data/updates etc via 3G. There have been many times where I just needed to do some 5 minute browsing using 3G only to have all the programs that access the internet starting up in the background and scoffing down megabytes that makes my head spin at the cost.

    Lastly, no navigation in Google maps yet?

    "However, things did get a little choppy on some of the more intensive websites like South Park Studios, which then, invariably took a toll on the battery life too. I’ll be honest, a warm Nexus One is not fun to hold in your hands...at all."

    You make it sound as if Flash is the only thing thats going to get the phone this warm. Playing Flash vids on Froyo does not drain the batter any faster than playing vids in a media player app, nor does it get the phone any hotter. The same goes for games.... but i dont see Apple not allowing video or games on there devices.

    Flash on Android 2.2 proves very well how well Flash can run on a phone (with a touch interface too), and that Apple, as usual, are talking BS.

    And i would have liked to of seen more on Flash performance in the article, not just a quick video mention on one site.

    "right, I'm sure they are going to get right on comparing a pre-release OS to unreleased hardware."

    Uh, that's what this article is all about (a pre-release OS, duh) which as of today is officially released to open source.

    iPhone 3GS and iPad are already out (duh) and iOS4 for iPhone was released to the public earlier this week and has been available by other means for a while.

    Many if not most of Anandtech reviews are done on hardware that has yet to be released to the public (duh). And we are talking a few days from release to the public (double duh). If iPhone 4 is still not available to Anandtech or they aren't allowed to publish numbers yet, that's fine, just compare to iPhone 3GS and iPad.

    It seems like old news (go watch the Day 2 keynotes of this years Google I/O conference on youtube and Froyo 2.2 on Google Nexus performance is already compared to iPad) and Anandtech is usually on top of these type of comparisons. Maybe because its Apple, they are being extra super careful to get everything exactly straight before releasing comparison numbers and incurring the wrath of Jobs.

    After tasting this Froyo article, I'm ready for the main course. Bring it!!!
