How to turn off processes (battery drain problems even in standby mode)?

I have the new iPad (3) and a number of processes keep running in the background even though I have "deleted" them in the multi-task pane, i.e., I have double clicked the circle, held down each app and then hit the red dash so that no apps are running in the background. For example, I keep getting notifications that apps need to be updated which means my iPad is checking with the app store - this is happening even though my notification center is empty. I also have a battery app that tells me 30+ processes are running even though I have no open apps. I understand that some processes must always run, but I would like to disable the unnecessary ones b/c I continue to have terrible battery performance, even in standby mode.

As for standby battery performance, the strange thing is that sometimes my battery doesn't drain in standby at all and then other times it drains over 10% over one night. Each time there are no apps running in the background and I have no idea what is causing the inconsistent behavior, but I can only assume there must some process issue.

Anyone have any thoughts?

Have you gone to Settings > Notifications and changed to Manually? That will mean it only checks when you want it to do so.

You can also go to Settings > mail, contacts, Calendars and set Fetch New Data to Manually so it does not keep checking for mail, etc.

Yup, did both those things when I first got it (it was even worse before I did that), but I haven't been able to figure out why I continue to have the uneven performance with everything set to manual.

Have you gone to Settings > General > Bluetooty and turned that OFF?

You can also go to Settings > General > Spotlight Search and uncheck things you don't want to spend resources searching through regularly.

When you will not be accessing WiFi or cell networks if you have that model, you can put it in Airplane Mode which will shutdown that radio transmitter, also.

I'm mostly concerned about the drain while in standby. I would not think that Bluetooth/WifI etc should be affected while in standby. For example, on my iPad 2, it NEVER drains more than 1% overnight while in standby in the exact same environment. In contrast, when my new iPad is in standby, it sometimes drains more than 10% overnight, but then there are times it doesn't drain at all overnight. It is this inconsistent behavior that is baffling.

If it discharges an excessive amount and turning off most services does not help it might be worth while taking it to an Apple genius bar and have the techs run sone doagnostics to see why it is discharging so much.

The quickest way (and really the only way) to charge your iPad is with the included 10W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.

Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.

At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
