Is there a way to control "sleep" in iOS7?

I was playing around with Auto-lock earlier, so I'm not sure if that's what I'm looking for or not. The reason is, let's say you set it for "1 Minute". Then after one minute, it turns off and "locks" itself----correct? What if you just want it to go to sleep for purposes of saving your battery, but you do NOT want to lock it? This is for a person who lives alone and is sitting right next to the device within arm's reach, and there is nobody else around who can touch it----thus, there is no need for it to "lock" every minute.

Is there a way for it to sleep without being locked and requiring a passcode to open it up again?

Thanks.

Okay, I'm a bit confused here:

If I set Auto-Lock to "Never", then the device will never require a passcode. That's fine----that works for us!

However, that brings me back to the original question. Can we control "sleep" on the device? If you turn on your device and use some random application, and then just place it down on the table and watch it, you will see that sooner or later the screen darkens, and shortly after that, it goes black and goes to sleep. How do we control this? On my iPhone, the screen darkens and then goes black all within about 30 seconds or less (I've never timed it---I'm just guessing). On my iPad, it won't go dark for at least a half hour---it just sits there with a bright screen and never dims or goes to sleep. Why the radical difference between the iPhone 5S and the iPad 4 (both with iOS7)?

Is there a way to control "sleep" with these devices? Thanks.

Ah, perfect! Thank you, JennaWolf---that is exactly what I was trying to figure out. Thanks for taking the time to figure this out. It's my b-day today, so this was a great gift to wake up to.......another problem solved. Yay!!!! 🙂
