Backdrops & Ice Carvings

Is there a way to see which apps are still running in the background? (I don’t mean the multitasking bar, which just shows the most recently used apps.) I have an iphone 3GS running on i4OS. I always press the home button after using an app, but I’m convinced that at least some apps continue to run in the background and drain the battery. During the night, when the phone is locked and on standby — no calls, no email, no safari, no ipod, no nothing — it’s been consuming about 3-5% battery power per hour. So I tried an experiment. I closed all apps in the multitasking bar, shut down the phone and fully charged the battery. Six hours after powering the phone up again, with no apps running and just a few phone calls, the battery is still at 100%! Wow. That means that before I ran this little test, there had been apps running even after “closing” them with the home button. The problem is, how to know which ones? Is there a way — an app, maybe — that would show which apps are actually running in the background and how much CPU usage they consume? It’s a nuisance to switch off 15 apps one by one on the multitasking bar without knowing which one is eating power. It’d be great to be able to hone in on the culprit. Preferably without jailbreaking the phone.

You might even be able to find an app that let’s you know, perhaps by email or text when spyware or any program has been upload to your phone.

Spyware can be installed on a cellphone in multiple ways without the owner knowing it and without another person ever touching the phone. For example, the owner of the device could download an application that secretly contains spyware or viruses. Some spyware can be installed onto a cellphone remotely, over a cellular or Bluetooth connection, or even by a multimedia messaging service message that the cellphone owner opens.
