How to Improve Your Laptop's Battery Life

Do you know that there are billions of computer users in the world and a very large percentage of them are laptop users? Out of every 10 computer users 7 users use laptop. If you use your laptop on battery power, you’ll know how annyoing it is to lose battery power at the “worst time”.  There are some guidelines that, if followed can help in improving the battery performance and keep it long lasting.

The simplest tip of all! Keep the laptop running on AC power instead of battery.If you are nearer to any charging point,then you should connect the charger to power it up AC.The reason is simple – when the AC power is ON, battery is not used at all.  Running the laptop more with AC power saves the charging and overall battery life.

Keep the CPU fan’s vents clear. If its vents are under the laptops’ body then make sure you’re placing it above the surface on which it is placed. This keep the air flowing under the body which helps in exhausting the heat from the vents. Remember heated system will force the fan to rotate faster which will require more battery power.

You can control or minimize CPU speed if you’re laptop is running on batteries.
To do this:
Open Control Panel > Power Options and Select the “Balanced” or “Power Saver” profiles to keep the CPU at minimum speed.

This is best if you’re working on single application like MS Office or just typing or watching a movie. You can create a custom profile for power settings by clicking “change plan settings” beside preset power plans.

Low amount of RAM forces the CPU to create a virtual memory inside hard drive. Accessing files from hard drive requires more battery power. RAM is not only faster medium of transferring data to CPU but also lighter on power resources and consume much less battery power.

Most of the users like to stand by the system when they’re away and it is assumed that from standby state system wakes up early. But in standby mode system’s hardware are still awake and eat battery power. It looks like the system is sleeping but actually it isn’t. While the Hibernation mode is useful when you’re running on batteries. Hibernating is little different from standby in which the system is completely shut down but the the opened programs, data in memory and opened files are preserved and you’re taken to the same state before hibernation when you turn it back on.  So instead of using standby try to hibernate it when on batteries.

LCD Screen and hard drive are the two most power consuming devices on a notebook. Turning off the screen saves a lot of battery power when you’re away for a while. Similarly dimming it also saves a good amount of battery charging. There are always shortcuts/functions keys given on all laptops to directly control the brightness of the screen.

USB devices, like flash drives, external keyboard and mouse etc are the biggest external sources that drain out the charging. If you do not need them when running on batteries, plug them out and you’ll notice a prominent increase in standby time.

Most of the programs are set on automatic execution when system is idle. While installing application some of them set themselves for automatic execution or say for example checking for updates online. Carefully check for all these type of application from Task Scheduler and turn them off when you want to prevent them from running while system is battery-powered.

This is the most obvious one. Applications running in background increase CPU usage. The more the CPU runs more the battery will be taken. Check the taskbar to see running applications and close all those that are not required. Try not to perform power-intensive activities while on batteries. Avoid multi-tasking  and playing heavy games.

The above  tips can easily extend and improve life of the battery of your notebook. You’ll definitely notice a huge increase in stand by time of your laptop if you perform all these.

Let me know if these tips helps you to extend your laptop's standby time.
