You're in a classroom, meeting, or getting some work done on the road, and unfortunately, your laptop is almost dead. For whatever reason either you forgot your adaptor, or there is no available outlet, and you need your PC to get your things done! But how to extend battery life and buy some time to respond on important mail, before it goes off? There are a few things you can do to buy you a bit more time on that almost dead battery. There are some preventative measures, and techniques to stretch your battery in emergency situations. If you are in a situation that you need your laptop a little bit longer, there is things to do to extend your battery life at the moment. But none of those methods will increase the amount of power inside the battery, but it will reduce the amount of power the laptop is using, and it will squeeze you a bit more precious time.
1 - ACTIVATE BATTERY SAVER MODE
First of all, Battery saver mode. Battery saver is designed with these sorts of circumstances in mind, it will engage a number of automatic changes to extend usable battery life. This saved profile will adjust your laptop's settings and shift components into low-power states to help you use your laptop a bit longer. This is done by adjusting settings to reduce power consumption, turning off not needed apps and processes, adjusting your activities to use less power.
2 - DISABLE UNWANTED DEVICES
The easiest way to reduce power consumption is to turn off or disable – simple like that. Every component in your laptop needs energy to function, it means it’s ruining your battery, but that doesn't mean you need power for all components, all of the time. Start by disconnecting any unneeded function at the moment, but make sure you don’t disable hard drive or processor, of course, only disable functions and devices easy to turn off – USB mouse, Wi-Fi, Bluetooth, Radio, external drive etc.
3 - ADJUST YOUR SETTINGS
While you'll still have to use the display and the keyboard,
you can adjust the settings for each to reduce the power drain. Start from keyboard
backlighting, if you are still able to see - put it off. While you need to keep
it up and running to use the laptop, you don't need it running at maximum
brightness or resolution. Reducing the display to 50-75% when you're running on
battery power can add a significant amount of time. Additionally, dialing down
the screen resolution to a basic 1,366-by-768 resolution or lower reduces the
amount of power used in graphics processing without negatively impacting your
ability to work. The last thing, if you really don’t need sound, turn it off, but
if you need it, keep it as low as you are able to hear, this will buy you some
4 - CARE OF THE BATTERY
It starts with taking care of the battery itself. If your
system has a removable battery, take care not to damage the battery contacts,
and if the contacts get dirty or damaged, it can reduce the flow of power.
Next, you probably heard about old tips about charging your battery to only 80
percent, and not leaving it on the charger all the time but this advice is very
old because today this doesn’t apply to Lithium-ion and lithium-polymer
batteries. While modern laptop batteries don't require you to be as conscientious
about how and when you charge your battery, sometimes take the opportunity to
let the battery drain completely through normal use. Clean laptop vents and
fan, in order to provide optimal cooling and airflow, as heat is a huge enemy of
your battery life in long terms.
5 - HAVE A SPARE BATTERY
One thing you can do when you are buying your laptop, the easiest way to ensure that you always have enough battery power is to bring along an extra battery - spare battery or an external battery pack. Laptops with a removable battery, the simplest option is a second battery. These batteries can be ordered directly from the manufacturer, or purchased from another company, usually for cheap. In order to save your battery health, swap the old battery for the new once when you are running out of power, change it with charged-up spare anytime you expect to be away from power.6 - KEEP IT SIMPLE
You can also stretch your battery life by keeping simple your own activities. Multitasking is fine when you have full power, and when you really need it, but running several programs at once increases the load on the processor. This drains much more power from your device. Adjust your PC use starting with single-tasking, for example when you need to type a document, close any unwanted programs. Doing this, you will get longer battery life by not running extra apps in the background.
