Use the power management settings on your computer that come built in. On Windows XP, click "Power Options" in your control panel. On a Mac, look for "Energy Saver" in System Preferences.


Switch off the wireless card if you do not plan to access your network or Internet connection. For Mac laptops, there is a button for powering on and off your wireless device is found on the toolbar at top.


Disable Bluetooth. If you don't use this feature, you can safely disable it to avoid draining your laptop battery.


Shut down or hibernate the laptop rather than using standby, if you plan on not using it for a while. Standby continues to drain energy to keep your laptop ready to go when you open the cover.


Turn off unused ports. Disabling unused ports and components, such as VGA, Ethernet, PCMCIA, USB, and yes, your wireless, too. You can do this through the Device Manager or by configuring a separate...

Keep Your Battery Going with Anti-aging Battery Technology

Anti-aging Battery Technology is a technology offered on Samsung notebooks designed to let you discharge and recharge your laptop battery up to 1,500 times. That’s better than three times the longevity of a standard laptop battery, which typically wears out after 300 cycles and three years of daily use.

Most battery damage occurs when the cells inside are at or near capacity. That’s because batteries get a bit hot under the collar when they max out their charge at 100 percent. This heat causes the delicate structures within to start to break down, which ultimately makes the battery less capable of holding a charge. Eventually capacity drops to the point where the battery won’t hold a charge at all and it has to be replaced.

Anti-aging Battery Technology works to avoid this problem by keeping your battery properly conditioned, thanks to a set of technologies that helps prevent this kind of damage to...

Notebooks tend to lose their charm quickly when you find yourself searching for a power terminal once in every couple of hours to help your dieing battery that is plunging towards the red zone! How do you keep your laptop/notebook battery going for as long as possible? Here are 15 easy tips to do so. Read them now. You’ll thank yourself later.

1. Sleeping Rejuvenates your Body, and your Laptop Battery Too
Use your laptop’s power management features (in Windows XP, under Power Options in the Control Panel; or in Vista, under Mobile PC in the Control Panel) sensibly. The system will run at lower processor speeds when enabling power management features and it will go into “sleep” mode faster when inactive. And if you can spare the extra time it takes for the machine to resume, make sure that you set your laptop to hibernate, not just sleep, when you close the lid.

Laptops have an advantage over smaller electronics when it comes to the battery. They have more room to put a power source in a laptop than phones or portable media players.

But as applications become increasingly demanding and your work requires more and more mobility, it's very possible that your laptop battery still isn't up to snuff.

Try these tips to prolong your battery life. Can you make it through the work day on a single charge?

Keep your laptop battery cool. Battery power saps more quickly when the battery is hot. Keep vents clear and don’t put your laptop on a pillow or other surface that will cover vents and trap heat. Don’t keep your laptop plugged in. If you rarely unplug your laptop, you’re leaving it in a state of perpetual charge at 100 percent. That's bad for the battery’s long-term health. Unplug it on occasion and let the battery drain. Put your computer to sleep when not in use. If you're taking a break, let your computer take one as...

I've been able to more than double the battery life of my netbook by turning off a bunch of services I don't need, and unloading their kernel drivers.

Use service --status-all to see what's running on your system, and service stop to shut it down.

Use lsmod to see what kernel modules are loaded, and rmmod to unload it.

If/when you want to bring things back, easiest way is to simply reboot.

Sometimes you also need to kill daemons or programs that are using the service or driver before they can be turned off. Look at output from ps aux to see what's running, and kill -9 to terminate them.

Services I usually turn off include: Ubuntu One, ssh, apache, databases, avahi, pulseaudio, cups, apparmor, acpi-daemon, bluetooth. Modules I unload: The whole audio stack, usb_storage, webcam drivers, wireless, bluetooth. (Some services like audio don't die easily.)

I've even gone as far as shutting down x (service gdm stop) and working entirely just from...

The lifespan of a laptop battery depends on a number of factors and is hard to predict. All rechargeable batteries wear out with time and usage. As time and cumulative use increase, the performance will degrade. For the typical user, noticeable reduction in run time generally will be observed after 18 to 24 months. For a power user, reduction in run time generally may be experienced prior to 18 months.

General Performance Tips

Update to the latest software.

Apple software updates often include advanced energy-saving technologies, so always make sure your device is using the latest version of iOS, OS X, or watchOS.

Avoid extreme ambient temperatures.

Your device is designed to perform well in a wide range of ambient temperatures, with 62° to 72° F (16° to 22° C) as the ideal comfort zone. It’s especially important to avoid exposing your device to ambient temperatures higher than 95° F (35° C), which can permanently damage battery capacity. That is, your battery won’t power your device as long on a given charge. Charging the device in high ambient temperatures can damage it further. Even storing a battery in a hot environment can damage it irreversibly. When using your device in a very cold environment, you may notice a decrease in battery life, but this condition is temporary. Once the battery’s temperature returns to its normal operating range,...

Most laptops don’t last too long once you unplug them from the mains. Some don’t even have removable batteries, so swapping the empty one out for a fully charged spare isn’t an option.

Here, we share our top tips for squeezing those extra minutes out of your battery. A lot of the tips are similar to those for improving smartphone battery life and no wonder: at their hearts, laptops and smartphones use a lot of the same technologies.

Whether you own a Windows laptop or are running a different operating system, follow these general tips and your laptop will last longer between charges.

1. Dim the screen

By far the biggest power drain on most laptops is the screen. Or, to be more specific, the screen’s backlight. This is what enables you to see the colours on an LCD screen, and some laptops have power-sapping fluorescent backlights. More modern notebooks have LED backlights, but even these use a fair amount of juice.

Discover what causes Li-ion to age and what the battery user can do to prolong its life.

Battery research is focusing on lithium chemistries so much that one could imagine that the battery future lies solely in lithium. There are good reasons to be optimistic as lithium-ion is, in many ways, superior to other chemistries. Applications are growing and are encroaching into markets that previously were solidly held by lead acid, such as standby and load leveling. Many satellites are also powered by Li-ion.

Lithium-ion has not yet fully matured and is still improving. Notable advancements have been made in longevity and safety while the capacity is increasing incrementally. Today, Li-ion meets the expectations of most consumer devices but applications for the EV need further development before this power source will become the accepted norm.

What Causes Lithium-ion to Age?
