How long a laptop battery should last after each charge?
After the laptop has gone through a full single charge and the power plug is unplugged the average life of a laptop battery can be anywhere between one and six hours. This time is dependent on the battery, its capacity (mAH), what's being done on the laptop, and how old the battery is. Over time the laptop battery total capacity decreases, which means the battery will not last as long as it did when you first got the laptop and will continue to decrease over time.
