[EDIT] You should also check Mac computers: Progress bar appears after waking from sleep - Apple Support

Dec 8, 2015 6:28 AM in response to mz_71by Linc Davis,Late-model Macs are configured to enter standby after four hours in sleep while on AC power, in order to comply with a directive of the European Union.
If waking from standby is slower than usual, please follow the instructions in this support article. Otherwise, see below.
You have two choices. One is to do nothing. Use the machine as designed. That's what I recommend.
The second choice is to increase the delay before standby mode is triggered, or to disable standby mode completely. This is an unsupported option and you're on your own as to the consequences. If you choose to go this route, proceed as below. These instructions are for advanced users only.
Please back up all data before making any changes.
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
Drag across the line below to select it, then copy it to the Clipboard by pressing the key combination command-C:
sudo pmset –a standbydelay
Don't copy the blank space at the end of the line.
Launch the Terminal application.
Paste into the Terminal window by pressing command-V. Press the space bar, then type the delay you want, in seconds. For example, if you want to change the standby delay from the default one hour to eight hours, enter 28800. Don't put commas or other punctuation marks in the number. To disable standby, enter 0 (zero.)
When the command is complete, press return. You'll be prompted for your login password. Nothing will be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. After running it, quit Terminal. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
To disable standby on AC power, enter this command:
sudo pmset autopoweroff 0
and to revert to the default state,
sudo pmset autopoweroff 1
