Do you feel that the battery life of your notebook never quite the statements in the informational materials equivalent? For example, the words “up to five hours,” but actually it is only half. One thing is sure: others are doing the same. I hear it again and if you at Twitter only shortly thereafter seekYou will find a lot of discussion on this topic.

I can assure you that this information is not hidden behind the intention to lead you astray. It deals with three simple factors:

1: The data are taken from the ideal case: Like the “number of liters per kilometer on the highway,” which is calculated according to the ideal case (with constant speed and driving over a longer period without having to stop and re-approach), the data is based on the DELL Latitude D830 Battery life on the benchmark MobileMark ? 2007. This value represents the benchmark for battery life, which runs the laptop and no applications have not even connected wirelessly to the Internet. An equivalent to the measurement of battery life in the “city traffic” does not exist – yet.

2: Different paths for different types of users: Laptop users are different. We all use laptops in a different way and this is how well different battery life. Some see the HD videos on YouTube, others may only send e-mails and still others play more games than others. ALL leads to different battery life. This Data from AMDillustrate this phenomenon. It is also a sign that the DELL Latitude D620 battery life may vary during use even more components to manufacturers.

3: Battery life varies over time: The older your laptop is, the longer you use it to load and charge again and again, the more the power to the battery. They are therefore the longest battery life on the first day experience in which you tear open the packaging. Have you ever noticed, how many are sold new batteries for old laptops? Some even claim that the Dell Studio 1737 battery life of temperature depends.

What you can therefore take as a consumer?

* Evaluate the DELL Studio 1537 battery life according to a curve, say 60%. The label says 10 hours, I guess it is probably in reality only 6 hours. (UPDATE: Please note this is not always linear.)
* Ask your dealer or system provider for the “number of liters per km in city driving” or apply the proven mobile phone compared to the “talk time”. Any distributor or system vendor has a website. And if there is no other way, you can ask them about Twitter.

I unfortunately could not be returned to you the 40% of your Dell Inspiron Mini 9 battery life, but hopefully you now know why you can not get only 60% of battery life!
