In an ideal world laptops would be able to run ad infinitum, and the role of laptop power adapters would be obsolete. Unfortunately, despite advances in laptop portability, laptops today are semi-portable at best, and after a few hours of genuine portability, it will come the time when you have to reconnect your device to the mains.
There are ways to increase the portability of your laptop, however, and plenty of things you can do to squeeze a few more minutes (and perhaps even longer) from your device:
Efficient Usage
Certain activities that you do with your laptop have a particularly high demand in terms of power consumption; for example, it is well known that watching flash videos on a Mac will greatly affect the battery life, which is one of the reasons that Apple don’t like to incorporate flash compatibility on their devices. With this in mind, by keeping taps on your activity while using your device you can save lots of power.
On a similar note, if you want to keep your device away from your laptop ac adapter for as long as possible, then you should ensure that things like your Wi-Fi adapter, bluetooth connectivity are switched off when not in use.
Manage Power Consumption
If you’re using a windows laptop then you will be able to “manage power consumption” from the power options control panel; for instance, rather than setting your laptop to go into suspend mode, which restarts your computer faster although consumes more energy, you can set it to go into hibernate mode which is much more “power friendly.”
Unfortunately, laptop power adapters and your laptop charger will be an instrumental part of laptops for years to come, but with the right power saving strategies you can greatly increase the power efficiency of your device.
