  1. I don’t think you can charge your cell phone too much……I’m not sure though. Just charge it for a night and when you wake up if it says that it’s done charging then disconnect it and begin your day!

  2. the battery will “remember” the charge level, and it will degrade the life of the battery.

    if you wait till its low to charge, it will go back to the capacity level.. if you keep it charged, it will slowly forget the highest capacity it holds, and wont be able to charge to that height after a while.

  3. The older ‘Ni-Cad’ (Nickel Cadmium) batteries would develop a ‘memory’ and would charge poorly after developing a pattern. The newer phones use Lithium Ion or Nickel Metal Hydride batteries. they are much less prone to any ‘memory’ problems with charging. However, most all re-chargeable batteries will begin to fail after a few hundred charges.. Many laptop computer batteries die an early life, since most everyone leaves their laptop plugged in all the time. The constant charge, no discharge, leads to an early failure, and short use time..

  4. If it’s an older phone, it might have a Nickel metal hydrate battery, which remembers the charge and over time, if you overcharge the phone, the battery life will degrade. If it’s a newer phone (say less than 2 years old) it should have a Lithium Ion battery and overcharging isn’t possible. Newer batteries stop taking in power once they’ve reached capacity

  5. When it over charges, it goes… BOOOOOOM!!! And then your house would go on fire and then your cell would obviously, be destroyed. If you don’t believe me, I said this to the twins before.

  6. Easy, the first time, you charge it for 14 hours, and then let it on until you use up all the power in the battery. Then you can recharge it like every other day.

  7. NOTING BUT OVER THE YEARS THE BATTERY WILL HAVE TO BE REPLACE CAUSE IT WILL HAVE A SHORTER LIFE

  8. You need to wait until the battery is low to charge your phone. The more you charge it, the less battery power it has. You dont need to read your instuction book…. just play around with your phone until your figure it out, you can learn it whenever you have time.

  9. And yes these questions and answers are for Lithium Ion (Li Ion) Batteries.

    What happens if I leave the battery in the charger for an extended period of time?
    Extensive charging may shorten the life of the battery. We recommend not leaving batteries in a charger for more than 24 hours.

    Initial Charge for a New Battery
    New Batteries may have some charge; however, to ensure maximum battery performance, a new battery (or battery that has not been used for several months) should be charged for at least 12 hours before use.

    Battery Performance Maintenance
    Best battery performance will be achieved when you regularly charge and discharge batteries.(In other words don’t charge it if it doesn’t need it.)

    Just because Li-Ion batteries don’t have a memory doesn’t mean you can’t shorten the life of them by overcharging.

  10. the new phones , the battery will need replacing sooner .
    the older phones , you might have overcharged .

    cheers !
