I heard that if you don't close/remove apps from the multitasking facility that this causes a lot of battery usage when not in use. I'm not good at remembering to close an app before I press the power button, what app is the best task killer. I know there are a few, at the moment I am using 'Advanced Task Killer' & it doesn't seem to work great in killing apps

There's no need for task killers.
When the OS needs apps closed, the system closed them by priority from idle.
Using a TK uses battery and more resources.

Along the lines of what DS said, if you use a task killer, it'll kill of apps in your RAM that android RAM management has decided you use a lot and should stay open. Then it gets into a cycle where RAM management opens something and your task killer closes it again. This uses more battery, whereas your battery will be used the same whether your RAM is full or empty.
Like I said, android RAM management will cache frequently used apps in RAM, so whenever you go to open them they are much quicker than if it would have to load them into RAM dynamically. Task killers often slow down your phone and use more battery then just letting it be.

@jamos you pretty much heard wrong. Try not to worry about what's running.
Speaking of Advanced Task Killer though, I use it (its kill widget) on rare occasions that any normal user will never encounter and it seems to work perfectly, it kills very aggressively.
What you're maybe noticing is that you'll use it and a few minutes later, apps will have started back up again.. This is exactly why task killers waste resources and shouldn't normally be used :thumbup:

Apps stored in ram aren't really running, they're just stored in memory so that they can be opened faster.
Since they aren't running, they aren't using battery.
Killing them opens that bit of RAM, but android sees its got more free RAM than needed to operate and will start adding apps back to RAM so they can be opened faster.

Always remember, if the power is on, the memory is powered. It doesn't matter if is occupied with "stuff" or not, it requires the same amount of power. BUT, ... Every time the system has to open an app (or reopen it) it takes processor time to shove it into memory. The processor does require power and changing state in memory to hold data takes power. So, killing something that the system needs takes the power to kill it and the power to restart it. IMHO, not a very good use of system power.
