### TERMS USED IN THIS SCRIPT AND `pmset` UTILITY
#
# [1]`sleep`
#   Refers to the kind of sleep in which the system still powers the RAM
#   and wakes up from the RAM. It's fast and doesn't write to the SSD,
#   but it consumes more power while sleeping.
#
# [2]`hibernation`,`standby`,`deep sleep`: 
#   They all refers to the kind of sleep in which the system writes it's whole
#   memory onto the disk and turns off power for RAM.
#   This type is the most power-saving but is the slowest to wake up from.
#
#   Because it writes the whole memory to the disk, it also uses SSD write
#   cycles and may have an impact on it's lifetime.
#   `standby` == `hibernate`.

### ABOUT THE USAGE OF `pmset`
#
# `-BATTERY-` means the value will be used when using battery and is set by:
# pmset -b [option] [value]
#
# `-AC POWER-` means the value will be used when using AC power adaptor and is set by:
# pmset -c [option] [value]
# ("c" stands for "charger" here)
#
# `-BATTERY & AC POWER-`  means the value will be used under both circumstances, set it by:
# pmset -a [option] [value]
# you can split it into two commands, one for battery and one for AC power, and thus create
# different settings for different situations.

###############################

#     Safe Sleep

###############################

### hibernatemode 
# Also known as `safe sleep`.
# hibernatemode = 3 is the default value on portables. The system will store a copy
# of memory to persistent storage (the disk), and will power memory during
# sleep. The system will wake from memory, unless a power loss forces it to
# restore from hibernate image.
# SEE MORE: type `man pmset` in terminal and look for `SAFE SLEEP ARGUMENTS`
# -BATTERY & AC POWER-
sudo pmset -a hibernatemode      3

###############################

#     Standby (deep sleep)

###############################

### standby
# Hibernates after the system has slept for a specified time period.
# -BATTERY & AC POWER-
sudo pmset -a standby            1   # Enabled

### standbydelayhigh and standbydelaylow
# Delay time before the system goes into full hibernate.(in seconds)
# These determines how long the system will stay in sleep mode (can wake up fast but consumes more battery)
# before writing its memory to disk and powering off its RAM (hibernate).
# `standbydelayhigh` is used when the battery is over a certain threshold and `low` is used when it's below that.
# The default threshold value is 50%, but can be changed by `pmset -a highstandbythreshold [PERCENT]`
# -BATTERY-
sudo pmset -b standbydelayhigh   1800 # (30 mins when above 50%)
sudo pmset -b standbydelaylow    900 # (15 mins when below 50%)
# -AC POWER-
sudo pmset -c standbydelayhigh   3600 # (60 mins when above 50%)
sudo pmset -c standbydelaylow    1800 # (30 mins when below 50%)
# NOTE that having a too short standbydelay will increase the chance of which the whole memory is written
# to the disk. This could be a bad thing if you are using a modern mac with a SSD since it increases the
# use of write cycles and will shorten the lifetime of your SSD in the long run.
# Default values is `86400` and `10800` (24hrs and 3hrs respectively), normally you want it to be slightly
# LONGER than how long you typically leave your laptop sleeping before using it again on daytime.
# This ensures fast wakeup when you're using it to do your job and makes sure that it goes into hibernation
# when left overnight.
# note that sleeping isn't going to cost you a lot more power than hibernation, so there's no need to set it
# to something extremely low like 5 mins.

### autopoweroff
# According to `man pmset`, it's an extra implementation of safe sleep to
# fulfill regulatory requirement, so it should have the same effect as standby.
# just set it to the same value as `standbydelay`.
# -BATTERY & AC POWER-
sudo pmset -a autopoweroff 1         # Enabled
sudo pmset -a autopoweroffdelay 3600  # (60 mins)

#     Misc.

###############################

### tcpkeepalive
# Mainly used by apsd(ApplePushServiceDaemon) to report the system's state of being online. 
# Often people find (in their `pmset -g log` output) that apsd and mDNSResponder is constantly waking up
# their system. Resulting in battery consumption (in my case about 25% over the course of 24hrs).
# Disabling this option prevents that because it keeps the system from connecting to the internet while sleeping.
#
# ! WARNING: Critical features like `Find My Mac` WILL NOT FUNCTION at sleep when this option is disabled.  !
# ! If there's a high chance that your laptop could be lost, set both battery and ac power to 1.       !
# -BATTERY-
sudo pmset -b tcpkeepalive       0   # Disabled
# -AC POWER-
sudo pmset -c tcpkeepalive       1   # Enabled

### powernap
# Wakes up the system while sleeping occasionally to check emails etc.
# depends on whether you need it or not, can be changed from System Preferences.
# Below is my configuration: 
# -BATTERY-
sudo pmset -b powernap           0   # Disabled
# -AC POWER-
sudo pmset -c powernap           1   # Enabled

### wake on magic packet
# Sometimes referred as `Wake on LAN`, this feature enables the device to be waken when a 
# special packet sent by usually another device on LAN is received.
# Not frequently used in real life scenarios, disabling it wouldn't cause any problem.
# But for the same reason, don't expect too much beneficial effects by disabling it.
# -BATTERY & AC POWER-
sudo pmset -a womp               0   # Disabled
