Does your laptop quickly run out of juice, destroying your productivity? Mine used to.
Now I have a Dell Inspiron E1405, with a 9-cell battery. I had it fully charged this morning. I’ve been working about 6.5 hours with no plug, and I have 35% (2.25 hours) remaining. That’s 8.75 hours.
What’s the trick? Well, first of all, it’s a 9-cell battery. That means it has more room to store juice. Second, I have my wifi and bluetooth cards turned off. Third, I exited all extraneous programs (Skype, Google Talk, etc). Finally, my screen’s brightness is down to one of the lowest settings.
But my point is that Dell’s advertising was correct – I’m getting 8+ hours out of this battery. You definitely wouldn’t get the same mileage while watching a DVD, but you can get some serious work done without a plug. That’s what I wanted, and I got it.
