[Windows Phone 7 General] N8ter:
The app takes up a lot of RAM because you've been using it a lot, probably reading tons of review/articles and long comment threads. Web Browsers do the same, on basically all platforms. The phone automatically manages memory. If you're stop trying to be a wannabe-geek and stop worrying about it, you'd see nothing comes of it. Engadget exits when you back out of it, btw... As does CNET and other apps like it...

Email apps WILL consume CPU time. They have to recieve push email, or poll for email. Hello? Are you that daft? The more emails you recieve, the more CPU it obviously will use because that application will be doing MORE work.

System has to do things. It's 3%. If you had said 30% then I would probably say there was a problem. Also, SYSTEM is a group of applications, not one applicaiton. It's just called SYSTEM so that your list wouldn't be overpopulated by apps that use very little CPU and show up at 0 or 1%. It just groups them all together. Again, you simply have no clue what you're talking about or how your phone works.

It depends on what you do with your phone. Some things are impossible to feel comfortable with on WP7 because some things are impossible to do on WP7. You can't use Apps like Layar/Skype or any decent IM application. You cannot use an HTML5 Web Browser with Flash support. You can't use Tango, or Kik, or WhatsApp, or Facebook Chat (Flory is terrible), or a ton of things. Look at the APIs that Microsoft is adding in Mango (still ~6 months away). You seriously think customers should have had to waid ~a year to get some of these things? Not necessarily from MS, but from the Marketplace where atm it's impossible for them to exist in any reasonable form or fashion due to the incompleteness of the OS...

1. On the Vibrant (with FroYo), when you long press it tells you the last 6 Apps you ran, and it has a dedicated Task Manager button.

2. Most applications exit when you back out of them, or use the Exit option in the app if available. Few don't, but most do. Applications that don't, should be uninstalled and refunded instantly because this is supposed to be standard behavior and they don't deserve your money if they are lazy in their coding and/or UI design (Exit Option).

3. The Task manager is built-into the OS and allows you to remove cruft from RAM to free some up and see what's running, as well as uninstall applications and end running applicaiton. Just cause something is running doesn't mean it's using CPU, though... Some applications just go dormant and sit there until the system needs the resources and purges it out.

There is no need for an Auto-Killer. See #3 above. The system comes with it's own task manager built in. The benefit of Auto-Killers is largely a myth. If an idiot wants to install one, more power to them.

The reason why they hardly help is cause most applications go into a dormant state when they background. They are in RAM, but they aren't doing anything. They aren't wasting battery or anything. Running an Auto Killer to kill them, however, DOES waste battery, and when you open the app again instead of opening directly from RAM it has to fetch the data from storage, which again wastes more battery. Over a usage session an auto-killer is a terrible idea, especially when it's constantly killing dormant applications that are otherwise not using resources. Some applications are dormant but have background tasks set up to recieve push notifications (some apps don't use C2DM, they use their own push infrastructure). Auto-Killing them is terrible...

I've read the market review. I read people with trash devices like Backflips or Cliqs ragging on applications that clearly state in the description which types of devices they support. I see people with Custom ROMs and hacked up phones like HD2s with Android gives 1 star reviews because the app doesn't work on their device, when it works on 99% of Native Android Phones with Native ROMs. I see people with G1s with 2.2 complain that an app doesn't perform acceptably on their device in the market... Ya think?

Market reviews are a joke. Everyone knows it. Yes, there are some good reviews from good people who try to be reasonable, but they are almost always drowned out by those whiners. That's why the Amazon AppStore is a good thing. A lot of trolls get weeded out there and you can read reviews there before getting an app from Google's Marketplace...

Maybe you should switch to a carrier that actually updates their phones? If the usages are so different, why are you still responding to me?

You, according to this thread. You're the one making the Captivate/Focus comparison, not me...

You solved one problem and created another. I'm almost sure 80% of the people who switched from Android to WP7 either keep an active SIM in their Android phone, or carry it with them as well to SIM Swap, etc.

There is a reason why there's a number of people trying to dual boot Android on their WP7 devices. WP7 is basically a glorified Feature Phone at this point and you can't get anything serious done on it.

Apart from Zune and XBL nothing is does is better than Android or iOS.

Also, WP7's seemingly better battery life is helped by the fact that it hardly runs anything in the background and apps do not have access to some APIs that are generally battery-taxing, like the Camera Stream and Sockets... That's not my opinion, it's a fact. And it is 100% related to the issue you brought up.

Ciao.
