I’ve had and power used the EVO for a week now, and I still love it, but there are a couple of things potential buyers and current owners should know. First, and foremost, the battery and the applications that plague it.

I am still toying with the settings, but if I the ability to control how apps run in the background is not natively configurable, Google will have to provide a patch that does allow a user to ‘set it and forget it’ where they can configure apps to “close (for real) upon exit”.
The battery life is horrid, absolutely horrid, on the EVO. But it may not be the battery that is the problem, and instead how Android keeps the apps running and opens a slew of ostensibly related other apps when just opening one app. For example, your Facebook app will also require your Internet control app to run. Often, very often but interestingly not always, other clearly not needed apps spawn such as “MP3 store”,” Sprint navigation”, ‘Voice dialer”, etc, simply by opening the Internet Browser, or Facebook App, or even simply scrolling over to another home screen on your phone (not accessing the Internet at all!). But I’m getting ahead of myself.
So this is just my hypothesis, but the notorious battery drain everyone is complaining about *may* be related to the plethora of apps that spawn when you don’t need them, and stay running on the Android OS after you have closed the initial program that absurdly caused them to spawn.
And how did I see these plethora of apps running? That’s another issue that is not too terrible, but Android does not ship with a few apps that I find are essential to using a smart phone. One being a task manager. Granted, there is one but it is buried a few layers deep (i.e.., no direct shortcut in the “apps” page) and it does not show you all the apps that are running. In that regard, you must go to the Android Market (app store) that IS wonderfully pre-installed on your device, and download a task manager. I down loaded the free “Advanced Task Killer” for this job, and it shows me all the apps that are running. Imagine my surprise when I first installed it and ran it to see 15 apps running in the background! 13 of which I was not currently using and had finished using hours before! Advanced Task Killer easily killed all the apps (except itself, of course) and runs terminally resident at the top border of your home screen for easy access. I have almost trained myself to religiously click it and wipe all running apps every time before I begin another application on my device for maximum performance of the app, and to prevent batter y drain. I have to do this each time, as I am flabbergasted at the long list of apps that spontaneously spawn just by looking at my “friends feed” app, for example. Another important note about killing all those apps is that it doesn’t prevent you from using those apps or even cause you to lose functionality (other than dynamic web form input or the last web page you were on, but we expect that to happen when we close our web browsers) when you killed them, nor does it turn off your Internet connection, ability to receive email, text, Google Talk, etc. notifications, when you kill the all these apps. It is this reason that I do not understand why Android keeps these apps running in the background.
Once I spend a whole day on the beach where I have religiously killed every app other than the one I am using not only after using them, but AS I use them and killing all the ‘piggy backing’ apps that spawn from launching it, I will know if this is the sole cause of the heavy battery drain.
Fortunately, I am always near some form of electricity (car, home, work) but as I write this, I am on my way to a cruise ship and will in my cabin very little, and on a Caribbean beach a couple of days during said cruise. This is where my battery drain will cause me frustration. I will use those beach days to get 100 percent consistent with my Task Killing practice and see if the battery is able to maintain a respectable life span. If so, Google will indeed have to send out a patch.
About the Android Market, I spent all day perusing *just* the “free apps” section and found everything I needed for my initial repertoire of ‘power using’ apps I had enjoyed on my former Windows Mobile phone. The paid apps section provided decently priced ($1-$3 typically) apps as well as more advanced functionality of some of the free apps. I think I downloaded 35 apps in one 30 minute session when I first got the EVO. “Advanced task Killer” was one of these apps, and when I ran it, every single app I had just downloaded and installed (did not run, mind you) was still ‘running’ in the background. It was the first time and only time I experienced the normally zippy fast EVO to lag as I used it. Killing all those apps fixed that.
And finally, the Qik application is very cool but there is one thing you need to know. The app that comes pre-installed is NOT the app you need to video call someone else who has the same app. They don’t tell you this anywhere in the main paged of qik.com. Instead, they give you a “tutorial video” that gives you a cute tech girl explaining how wonderful the Qik video calling application is, then she proceeds to “make a call” but the video skips past showing where she clicked inside the application to initiate the call. This was intensely frustrating for me, because I was specifically watching that video to figure out where in the Qik app I could find the video calling ‘button”. I was scanning her hand movements to see how she initiated that video call, then bam, it skips that part and just shows her ‘office buddy’ receiving the call in another part of the building. The video calling page even tells you to simply “pick from your contacts, and initiate the call!”. Turns out, you need to go the Android Market and download and install over top of your pre-installed qik app the version that DOES allow video chat. Thanks Qik, for causing me to burn 25 minutes figuring something out that you could have just “said” on your intro page. Furthermore, you were demoing the EVO 4G as the device you were using!
One thing I also want to add to that ‘tutorial’. They depict the video quality during their “trial” video call to be absolutely superb. This would be because they were using their office Wi-Fi or true 4G network to make the call. If you are still on 3G, expect it to be very pixilated and only useable if you and your calling partner sit very still while chatting. That’s how my test went.
Aside from these issues, and a few I will blog about later, I do like the super fast response of the EVO and I recognize a lot of my enthusiasm is because I am new to Android and very happy that the Android app store is huge enough, and growing, to allow me to do almost everything I was able to do with my old Windows Mobile phone.
