What's the rule for proper etiquette for phone chargers? Now, this is on an ongoing tussle in my home. I plug my phone in to charge. I come into check on it from outside and it's unplugged from the charger and my daughter has her phone charging and my phone reads 72% charged. I go "What's up, my phone was charging?" My kid goes that I had 72%. And her phone was really low. I don't think 72% will give you a passing grade on most tests. Why is it fine to unplug my phone from charging? Going on a trip do you fill your car or just gas it up to 72% full? I like to have my phone fully charged. That means 100%. Now not to just throw my daughter under the bus, my wife pulls this same stunt with the phone charger. Etiquette seems to be the least important of all laws when it involves cell phones and charging them. Wheres the code of conduct? You shouldn't talk with a full mouth. It's okay to talk with an empty head. (Look at a lot of our politicians.) An individual's desperation of having next to zero phone charge allows them to do the wrong thing but for THEM the right reason. I told my family last night that if my phone is charging and reads 72%, it's not fully charged. So leave it be. My wife rolled her eyes. I asked my spouse if I had told her before we got married I love you with 72% of my heart, what would you have said? I'm assuming you would have responded: "Well that's not enough." Right! She goes, "I would have suggested instead of getting married, let's skip right to the divorce, and I would get custody of the phone charger.
