There are a number of ways to judge a laptop's value, but at the top of the list may be its battery life. After all, what's the point of owning a portable computer if it can't run without outlet power for more than a few minutes, or if its battery seems to be the reason it requires constant laptop repair? While some computer makers tout their laptops as the best when it comes to battery life, consumers need to recognize a few factors so that they can make their own judgment before purchasing.

Balance battery life and needs

Consumers might want a laptop with plenty of battery power, but experts say they ought to question whether they really need their computer to have this ability. Consider that some people now desire laptops with powerful processors to replace old desktop PCs. In this scenario, long battery life may not be as important a factor, since the laptop will likely remain on a desk and connected to AC power most of the time anyway.

Some manufacturers sacrifice convenience to achieve longer battery life

When reading laptop reviews, consumers ought to take measures of battery life with a grain of salt. Some computer manufacturers produce laptops with weaker low-voltage processors in order to lessen power usage. Conversely, other manufacturers may pack a computer with a massive, clunky battery that aims to generate more power at the expense of portability and convenience.

Consider smaller laptops

As a general rule of thumb, consumers looking to find ultra-portable laptops that will run without outlet power the longest may want to lean toward smaller computers. Netbooks, for instance, include small screens, processors and pricetags, making them an affordable option for users who want long battery life. There are a few standard size models that may provide the most power without sacrificing size and performance, and the sturdiest may require fewer trips to a Maryland laptop repair shop.
