The short battery life of a laptop can be annoying for the user. Laptops have gained popularity mostly for their mobility. Users can take laptops outdoors or far from charging ports and do their tasks. However, when a laptop's battery gets weaker it hampers its mobility. In most cases, they need to use laptops while plugging them in. This issue is limiting. But with just a few tweaks in daily use, you can ensure a long-lasting battery life for your laptop. What Is Laptop Battery Life? A laptop battery is a rechargeable device that powers a laptop without needing to be plugged into a power outlet. Located on the underside of the laptop, it is easily replaceable. There are different types of laptop batteries such as nickel-cadmium, nickel-metal hydride, and the most common, lithium-ion, which is preferred for its higher energy density, longer lifespan, and lighter weight. Typically, a laptop battery lasts between 2-5 years or 300-500 charge cycles, depending on its type, age, and usage. Factors such as frequency of use, running applications, and power management settings can affect its longevity. Read more: Asus ROG Strix G16 Review: Is it a value for money gaming laptop? Tips to Increase Laptop Battery Life . Never Reach Zero To extend your laptop's battery life, don't let it drop to zero. Many people also ask if they should charge their laptop to 100%. The answer is no. A full recharge can be as harmful as letting it drop to zero. The only time you should let your battery drain completely is when you're installing a new one. This helps calibrate the battery gauge for your device. Optimize Your Battery Setting Your laptop has settings to help extend battery life. If your battery dies quickly, try this: type "battery" in the Windows search bar at the bottom left of your screen. This will open a window where you can turn on "battery saving options" and find other ways to improve performance. Lower your screen brightness. Look for a function key on your keyboard with a sun icon. Press it and use the arrow keys to reduce brightness. You can also find this setting by searching "display brightness levels" in the Windows search bar. Read more: Best MacBooks in Bangladesh: Which Apple Laptop Should You Buy? Close Energy Consuming Applications Closing energy-draining applications on your laptop helps the battery last longer. To save battery, close applications that are not in use. Typing "battery usage" in the Windows search bar shows which apps use the most battery. For example, Google Chrome might use 45%, Microsoft Excel 21%, and Microsoft Word 9%. Closing the biggest battery drainers, like Google Chrome, can help. Another tip is to switch the laptop to airplane mode to reduce battery consumption. Adjust Display and Graphics Settings A graphics processor on a laptop can drain the battery significantly. Opening the "battery usage" screen will show how much battery it consumes. If the usage is high, adjusting graphics settings can help save battery power. For instance, reviewing program settings and assigning different applications to specific graphics processing chips can reduce battery load. Games can be aligned to a discrete graphics card, while everything else can be set to use integrated graphics.

The material can block the battery ventilation ports, causing faster wear. Before putting your laptop in its bag, power it down or switch to standby. Once you arrive at your destination, unpack your laptop. Use a flat, hard surface like a desk instead of a softer one, like your lap, to improve airflow and conserve battery life. Additionally, dirt and debris can clog ports and force the battery to work harder. Compressed air can easily remove dust and help normalize battery consumption. Go For an SSD Replacing your laptop's hard drive with a solid-state drive (SSD) can make a big difference. A laptop will go from slow to fast, like a total transformation. With an SSD, everything runs quicker, so you can open files fast and finish tasks in no time, which also helps save battery life. Plus, SSDs use flash memory, which uses much less power than traditional hard drives. This means your laptop's battery will last longer with an SSD.

This makes programs run smoother, helping to save battery power more effectively. Moreover, updating your OS might introduce advanced power-saving modes that further optimize battery usage. Additionally, you might get a smart charging mode that improves how your laptop charges, making it more efficient. Conclusion By maintaining a few guidelines, users can significantly extend the battery life of their laptops. From simple adjustments to more substantial upgrades, there are various strategies available to optimize battery performance and enhance overall efficiency. Whether it's avoiding full charging, adjusting settings, closing energy-draining applications, or upgrading hardware, each recommendation plays a crucial role in maximizing the battery lifespan of a laptop.  Read more: World’s First Transparent Laptop by Lenovo: A Peek into The Future

Lithium-ion batteries have been ruling the world for storing electricity since they were invented. From simple charger lights to giant electric cars, most modern devices use lithium-ion batteries as their powerhouse. However, they have gone a little off-fame for their explosive nature and safety concerns for large-scale grid energy. To overcome the risk, a multinational team of scientists, researchers, and industry collaborators have come up with the world’s first water batteries. These batteries are claimed to be less toxic, recyclable, and incombustible. What is a Water Battery? The concept of a water battery is not avant-garde. However, experts have been trying to make an ideal version of such a battery to use in the industrial field for a long time and finally succeeded. A traditional battery uses organic electrolytes as a conveyor of electricity between negative and positive edges. Interestingly, in a water battery, pure and plain water serves as the electrolyte.  It took a fair deal of effort to make a water-based battery an acceptable, stable, and modern technology that is usable all across the digital industry. In the manufacturer's terms, these batteries will be termed as aqueous metal-ion batteries.

These batteries are safer than lithium-ion ones, as they don't catch fire or explode. They utilize water instead of volatile materials. The team's breakthroughs in aqueous energy storage devices significantly enhance performance and lifespan. Their manufacturing simplicity allows mass production, utilizing abundant, inexpensive materials like magnesium and zinc.  Unlike traditional batteries, water batteries use water as an electrolyte, replacing hazardous substances. They work similarly to lithium-ion batteries but without the associated risks. Additionally, managing water levels in these batteries is crucial for longevity and requires periodic replenishment to maintain efficiency. This innovation offers a safer, more environmentally friendly energy storage solution for various applications.
