Performance

Going from virtually any phone to the EVO 4G will be a pleasant experience. Die hard iPhone users will notice one thing however: choppy animations.

There’s lag or choppy animations when scrolling down a page, swiping between screens and generally interacting with the phone. What’s even more frustrating is if you leave a lot of apps resident in memory there are times when the UI will stop being responsive. If you have haptics turned off there’s no way to tell whether or not a button tap was recognized, often resulting in a double or triple tap which then results in an unintended phone call or similarly frustrating action. It definitely hampers the experience.

The best way to describe it is by comparing it to an old PC that just starts swapping to disk because it runs out of memory. It’s worse than anything I’ve seen on any other Android phone I’ve used (Nexus One, Incredible).

Remember how happy I was that HTC largely fixed the choppy scrolling of the Nexus One with the Incredible? It’s broken again with the EVO 4G. In fact, scrolling appears to be even worse on the EVO 4G than on the Nexus One for some reason. Given that this is mostly the same underlying hardware I can’t help but think it’s a driver or software optimization problem.

All I'm doing here is scrolling and running Task Panel

Scrolling isn't GPU accelerated, so a quick flick down a page will drive CPU utilization up to 40 - 50%. The only way around this is to either optimize the crap out of the code or move to dual core CPUs so there's another core ready to handle anything else you throw at it. Combined with a lightly CPU intensive app I found that scrolling can sometimes even send CPU utilization up above 70%!

To measure web browsing performance I downloaded a bunch of different web pages and saved as much of them as possible locally on a server. I used WiFi (802.11g) on all of the devices to connect to my local server and timed average load time. I repeated the test at least 3 times and threw out any unusually high or low numbers. Performance on the Android devices was from a clean restart with no unnecessary programs running in memory.

What these tests should show is the overall performance of the platform when all network bottlenecks are removed. Obviously hiding in a tunnel under a lead umbrella will make any phone slow, but we’re looking at peak performance here.

The first test is the new AnandTech front page. Here we’ve got tons of images and HTML, meaning we’re stressing both bandwidth and code parsing speed.

The EVO 4G is actually slower than the Incredible, which isn't totally surprising given that the device actually feels slower.

Next up we have the first page of our recent Zotac XBOX HD-ID11 review. The balance shifts from tons of images to more HTML processing:

Here the EVO actually inches ahead over the Incredible, but none of the HTC devices are still as fast as the Nexus One.

Using our Print this Review function, this next test loads our entire 2010 15-inch Macbook Pro review. While the other two tests had some flash ad content, this one is completely devoid of it so the HTC phones shouldn’t be penalized:

This is quite possibly our most unusual result - the EVO 4G is actually faster than the Nexus One and Incredible.

Our most intensive test is up next with a load of the Engadget front page:

And now we're back to normal, the EVO 4G is about the speed of the Incredible in our longest test.

Our most CPU bound test is up next. I put together a custom page with a ton of tabular content and a single page copy of our 15-inch MBP review to make the load take some time at least.

Once more we're a bit faster than the Incredible here.

Javascript performance shows that the HTC phones have the potential to be fast. They both outpace the Nexus One here:

Overall the EVO 4G tends to be about the speed of the Droid Incredible in terms of web page loading performance. Sometimes it's faster and other times it's slower. The Nexus One still loads web pages the fastest, while the Incredible has the smoothest UI.

    Last I knew, it was free roaming regardless. The minutes is just anytime, which for Sprint is 7am to 7pm (free nights and weekends). But like you said, you get unlimited mobile to mobile regardless of the other person's carrier.

    I wonder how this thing will stack up against the Samsung Galaxy S phones? I believe all the major carriers are getting one.
  • ed1112ward - Monday, June 28, 2010 - link

    Yup, as a owner of the phone i can confirm then $10 evo tax, err I mean "Premium Data" charge.
  • ChillyPenguin - Monday, June 28, 2010 - link

    The 69.99 plan only include 450 minutes to land lines, while it does include unlimited minutes to any cellphone on any network. This review is correct in listing the 900 minute plan as 99.99 including the $10/mo 4G fee. That being said, my wife and I are on a sprint "Simply Everything" 1500 minute shared plan. By the time we get free calling to all cell phones and free nights and weekends, we used less than 300 minutes combined last month.

    It's hard to really compare AT&T prices to Sprint prices since you can't get the exact same plans most of the time. Sprint truly has an "unlimited everything" option while AT&T has a 2GB max limit now. The fact that AT&T ended up being cheaper once tethering is included means little if you go over every month. With 4G and a true unlimited plan it's a pretty safe bet to say that Sprint has a much better plan in place. You can actually use it like it's supposed to be used.

    I'm very disappointed to hear about the screen in the EVO. A TFT, really? Why sully a great device with a craptastic screen? Not that the screen can't look good, but it'll never look as good as an AMOLED.

    And I agree with another person on here that this topic needs to be revisited with Froyo on the device. Would also be worth noting if there is a difference between stock and a "formatted" phone so-to-speak. It would suck to see a stock phone behaving like most stock laptops, but it's still something I'd like to know.

    In some areas, sure. Like display size, aspect ratio and the built in kickstand. But I would argue the EVO 4G loses that title by having a worse panel type and dot pitch over the new iPhone 4; and, most importantly, such a short playback time whist in Airplane Mode.

    PS: To extend your entertainment needs one can continuously charge their smartphone from their laptop if on a long flight without access to power. You should be able to get at least 4 charges out of the average notebook.

    I'm waiting to see how the Droid X pans out. Unfortunately, Verizon is quite a bit more expensive than Sprint, and they don't have any "4G" options. Never been a fan of HTC either.
  • Zebo - Tuesday, June 29, 2010 - link

    Great review Anand. Good things come to those who wait, right.:P

    Evo is a non starter for me since I spend at hours on the phone each day and in the field and battery life kills it in addition to poor screen outside.

    Looking forward to iPhone review on battery life and outdoor capability.:)
  • fifoloveritas - Monday, June 28, 2010 - link

    The 30 charge is for wireless hotspot, which is not available on iPhone. Not sure if it's available on any other phone. There's no charge for regular tethering, phone has Share Connection option when it is plugged into USB.

    Anand,

    I've noticed that the majority of articles on the site lately have been for phones, consoles, laptops and other pre-assembled consumer electronics. Is this the new focus of AT? Has there simply been a dry spell of PC components?

    Thanks,
    MP

    I've got a stack of SSDs here that need work and we'll have new GPUs coming very soon. The smartphones are hot right now but we'll see things come and go in waves. If there's a demand for us to review it, we will :)

    Take care,
    Anand
