I have only had this MacBook Pro for a few months. I have been using my iPad lately. Today for a training for work, I disconnected my MacBook from charger, and placed in my bag pack. (Oakley bag, with padded slot for laptop). A few hours later (my bag had been sitting on floor) I pull out MacBook and it is very hot. And battery is down from 100% to 74%. What would cause that? Why did it not stay asleep? Thanks.
 
Do you manually press button sleep on apple logo or you just close lid? Use manually sleep press.
 
I will try that. Because usually I just close lid. Thanks.

Closing the lid is enough. Manually putting it to sleep is exactly the same, and not required.

Your problem lies someplace else. Do you have any connected bluetooth devices nearby while it's sleeping?

Well my watch and phone. If I have my computer on, the messages get sent to my comp, and phone. I figured when it was closed that wouldn't matter. I have never really paid attention to see if it happens while I'm around the house. But I'm pretty sure it does not.

Check in System Preferences > Energy Saver and ensure that "Enable Power Nap while on battery" is not checked.

This! Power Nap allows your computer to periodically turn on from sleep to check emails, system updates, time machine backups,etc. Mine will occasionally wake from sleep while plugged into my external monitor, brining the monitor out of sleep for a few seconds. The monitor never fully turns on, just shows a signal found on the HDMI port, then a few seconds later shows no signal found, then puts the monitor back to sleep.
 
Stanby/Sleep mode you would normally lose about 5-6% battery life in 24hrs. That's how much mine draw but some people it might be higher. I normally just shutdown instead of sleep. It only takes 20 sec to boot up, the only downside is you cannot use TouchID to login from shutdown typing password is slower than fingerprint.
