The batteries always create some concern to the users regardless of their location as laptops are integrated in their work, education, and entertainment life. The greatest portion still faces the problem of battery drainage and the inability to use gadgets without the physical place of electric connection, despite the high-tech hardware and software. What most users do not know is that even a few tweaks and strange settings can actually make the battery life to appear dramatic in real-life but does not influence performance.
Optimize Screen Brightness

Laptop screens are one of the biggest battery consumers. The brightness level can be adjusted to the lowest comfortable brightness that can significantly contribute to saving your battery life.
Use Battery Saver Mode

System settings will also have a battery Saver or Power Saver in new laptops. This mode can be switched on so that it minimizes the rate at which background activity will be conducted and will even limit the performance but will not be noticeable by the normal activities.
Manage Background Apps

Background apps will drain in battery power. Look in your task manager or activity monitor at regular time intervals and shut the programs you do not necessitate and do not let them drain their energy without making noise.
Adjust Power Settings

Windows, macOS and Linux possess high-level power optimization which can be sustained in high durations. To save battery, it is possible to reduce a time interval between two when the screen is off when the laptop is turned off and at the same time makes the laptop sleep up sooner.
Disconnect Unused Devices

The USB devices and the Bluetooth devices as well as the SD cards use power even when they are not active. Disconnection of these accessories when not in use can also help to increase the life of your battery.
Reduce Keyboard Backlight

Keyboard back lights may look cool to use but they also consume power. You need to turn it off when you are not in need, especially in sunny places and put it to the minimum brightness so that you can save the battery.
Use Airplane Mode

It is always good to switch off Airplane Mode when you are not required by Wi-Fi or Bluetooth to save wasting the battery in searching the network. It is useful especially when in the field or use of the availability of the Offline applications.
Keep Your Laptop Cool

Heat influences battery efficiency. Make sure that you got a clear-vented laptop. Sitting it in a flat surface rather than lap or a soft surface also stagnates the air and increases the life of batteries.
Update Software Regularly

The characteristics of battery optimization are available in operating system and driver updates. To ensure that your systems are up to date the manufacturer will ensure that you are supplied with all the recent efficiency boosts.
Calibrate Your Battery

In other cases, re-calibration of the meter of the battery can be achieved by emptying the battery to a low level and charging the battery entirely. This renders the system precise in regards to indicating the remaining battery life and this has the potential of improving the overall system performance.
Use Dark Mode

Dark Mode of applications and system menu does not just save power, especially in the case of laptops with OLED displays or with high contrast displays, but also helps to avoid eye strain.
Limit Visual Effects

Flashy effects and graphics within your operating system might not be ugly, however, they use processing capacity and battery.
Close Browser Tabs

Web browsers are battery consuming, high frequency, especially when many tabs are open. Systems with unnecessary tabs need to be closed and extensions, which block a tab, can be handy in reducing CPU load and enhancing the battery life.
Optimize Startup Programs

There are too many applications which are launched during the booting process and those which do not even require their services.
Unplug When Fully Charged

You should also ensure you leave your laptop plugged despite the fact that it is charged to reduce battery life in the long run. Leaving a phone unplugged even after complete recharge, as well as, charging it once the battery is drained are some measures that can be taken to conserve the battery.
