The average lifespan of a laptop battery is generally regarded as about 1,000 charge cycles. That number can vary depending on the laptop’s brand and battery, as well as how it’s used. It’s also important to note that performance can still degrade over time.
It’s difficult to say how long one charge cycle lasts on a laptop as it depends on multiple factors. Some laptops have batteries that can last tens of hours, while others (particularly gaming laptops) tend to only last 4-5 hours at most. If you’re concerned about how long your laptop battery lasts, check the manufacturer’s site to see how long the average charge should last.
