Are tasks restored upon startup?

[anon(660577)]

I have an original HTC Incredible and I think Froyo is the last update Verizon pushed out for it. Not rooted or anything.

I shut my phone down every night by pressing the power button and then selecting Power Off from the menu that pops up. Lately, I find that when I start the phone up the next day, the apps that were running the night before at the time of shutdown are sometimes shown in the task manager (no special task app, just holding the home button) and still running. Sometimes, I find the task manager shows no apps, as I would expect. I don't know if these "sometimes persisted apps" is a new thing, or if it has always been this way; I have only taken note of it in the last several weeks.

Is this the expected behavior? Does Android persist and restore apps after a power down/up cycle? If not, what is going on?

Is the phone not actually powering off? I know that before Froyo, the phone would vibrate when it was powered down, and it no longer does. I assumed that was taken out in Froyo, but it always bugs me that I can't be sure the thing has powered down.

Selecting power off from the power button menu (power off/airplane mode/restart) actually puts the phone into a sleep/hiberate mode. It does not completely power down. Only pulling the battery will completely shut the phone down. Restart will also shut it down, but of course it will restart afterward.

That helps a lot, thanks! I had always assumed "power off" would do just that. After all, when subsequently turned back on, the phone does go through a "boot up" process that takes a length of time.

It just must be the case that it has always been this way, but I just never checked the task manager upon startup.
