When it comes to keeping your laptop battery running for as long as possible, there are a few simple guidelines to follow. Heat is one of the biggest enemies of laptop batteries, so it's important to keep your device away from direct sunlight and other sources of heat. A battery stored at a winter temperature of 32 degrees Fahrenheit (0 degrees Celsius) maintained 94 percent of its charging capacity, while a laptop computer at 104 °F (40 °C) retained 65 percent. It's also important to find out as much as you can about your laptop and its battery.
Devices like iPhones come with native battery maintenance settings and alerts that provide at least some information, but these diagnoses are harder to find on laptops unless you install them yourself. iFixit has a wide variety of laptop batteries from most major manufacturers, along with guides and tool kits to help you replace them yourself. To get started, visit the power settings corner of your laptop and learn how the battery works and what battery settings you should enable. Once the battery reaches 100 percent, most modern laptops stop charging and instead energy is diverted to the system.
You can also set a maximum battery charge threshold on some laptops, such as Lenovo Vantage for ThinkPad laptops, Samsung laptops, and Sony laptops. Additionally, it's important to put your laptop into hibernation before the battery runs out completely, as well as during idle time when you won't be using the laptop for a while. By following these simple tips, you can ensure that your laptop battery will last for as long as possible. It's always surprising how much longer you'll want to keep your laptop perfectly configured once battery life is known, not a complete mystery.
