Question: How Do I Know If My Cell Phone Battery Needs to Be Replaced?


  • Cell phone batteries usually last between one to two years, which equates to approximately 300 to 500 charging cycles. If the phone battery is older than two years, it should be replaced.
  • Turn the phone off and place it into the charger or insert the charger connector into the cell phone. Allow the cell phone to charge for the amount of time recommended by the manufacturer. The average charging time is usually between 4 to 6 hours.
  • Remove the cell phone from the charger and immediately turn it on by pressing the phone's power button.
  • If the battery level is lower than full, it indicates that the battery is not fully charged. This means that the battery is getting old and the level of charge it holds will continue to decrease. Replace the battery as soon as possible.
  • Use the phone as normal and pay attention to the battery level. If the phone dies within a few hours, or the battery level drops rapidly, this is a sign that the battery should be replaced.
