Draw katana, dead. Unzip, cum.

I don’t keep track of it it’s just another thing to occupy your mind. Just charge when below 30 and unplug above 80. The always on display only gonna drain 1% battery per hour ( similar battery drain amount on android) if you want to save more just turn on battery saving mode, turn off always on display, turn on airplane mode, turn brightness to minimum, deny every optional privacy settings, turn location services off and turn off background activity

In that case if your always on display is set to on then it’s normal

Depends on what phone you got

Read the words after “because”
