Why does the cord say unplug the cell phone when its full charged? I thought modern batteries were beyond that

Answer 1

It's to reduce energy consumption. If 10 percent of the world's cell phone owners did this, the group's final report said, it would reduce energy consumption by an amount equivalent to that used by 60,000 homes per year. It's an environmental intiative, beginning in 2007 so phones will feature an alert to notify the user.

Answer 2

Batteries are like my students when they get full they just wont hold anymore!!! You have to teach your batteries to use there charge, if you only let them use 1/2 charge before you plug them back in then that's as much as they will charge, so you want them to run down. The newer batteries have moved beyond that but I think, if you remember not to long ago Apple was having problems with there computer batteries over heating.

Answer 3

Yes, one might think so, but it's not the batteries so much as the chargers that have changed to eliminate overcharging. Your cell phone uses a simple charger that does not monior battery voltage. So, if you never unplugged the charger, the battery would get too warm for its own good.

Answer 4

no they are not. it is the same with a laptop computer. when the laptop battery is charged and the laptop is plugged in, the battery needs to be taken out whilt the laptop is in use. the battery should only be put in when the computer is unplugged. the same goes with the cell phone. the only time the battery should be used with the phone is when it is unplugged unless the battery is charging.

Answer 5

So you don't over heat the battery and you don't start a fire.

Answer 6

its so you would not over heat your battery

Answer 7
