How long a laptop battery should last after each charge?

Laptop batteryAfter the laptop has gone through a full single charge and the power adapter 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's 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.

The more software programs that are open and running on your laptop, the less time you will get from the battery. When more programs are open, it requires more power for the laptop to keep the programs running. Other factors that affect the battery life include the brightness of the laptop screen, an active WiFi connection for Internet service, and if you are listening to music or watching a video. Each of these will also reduce battery life.

What's the overall life of a laptop battery?

A laptop computer battery should last between two and four years, or around 1,000 full charges. The total lifetime of a battery is dependent on several factors. These factors include battery type (NiCad, NiMH, or Li-ion), how often the battery is used, and its age.
