Your logic has a big gap. Apps use power when they take up CPU time (are running). Just because they are in RAM means little. Most apps are frozen when in RAM and make no significant difference in power drain. There are exceptions, like GPS, music, downloads, and a few others. Even then there is only room in RAM for four or five apps. Most of the listed apps in the multitask bar have long been removed from memory.Quote:

Not that this makes any practical difference if you run a lot of apps that actually do run background tasks. They still need to be removed if you want the best battery life. I'm only making this point for accuracies sake, and to hopefully head off some future arguments of the general type of my-iPad-does vs my-iPad-dosen't. It is about what you are running, not how full your RAM is.
