iPad feature request: auto "deep sleep" after 24h idle (10 seconds to wake is okay). iPads used to last over 30 days on standby, but every time I pick one up now after less than a week it's dead

Steve Jobs announcing the iPad 2:

@christianselig do you have a Pro with an Apple Pencil attached? I find that keeping my pencil attached drains the battery super fast but when it falls off in my bag, the iPad lasts forever in standby
@bmpitzen I have several so a few without Apple Pencils and they still are rough :(
