I can use org-mode to log battery recharge and battery discharge durations with a basic org-mode table and in the event the discharge duration starts dropping off sharply maybe get to a store and replace the phone. I put two inactive time stamps in a field for recharge and discharge and beside both of those fields I have a duration field where I do the math and record the hours and minutes. I have an ~/org/logs/iphone.org file and have other directories under that ~/org/ directory too. --
