How Long Does the Laptop Battery Last?

laptop batteryIt depends on certain aspects, such as how much a laptop gets used, laptop model, specifications, battery type, and so on. Generally, 2-5 years of lifespan i.e. about 300-500 charge cycles is concluded. If we talk of how much a laptop battery can last in one charge, it’s ideally between 2 to 12 hours depending upon the age/condition of the laptop.

If you own a high-end laptop, the battery in it may last longer as compared to inferior models. However, if the battery is kept maintained, it can go a long way. You can keep it maintained by not overcharging or getting drained so much before plugging it in to charge. You can further optimize power settings, avoid high temperatures, and so on.

What are the Reasons for a Laptop’s Low Battery Life?

Enlisted are certain common aspects that contribute to a laptop’s low battery performance:
