XPS 15 L521X: What is your battery life?

I have factory built with only two changes, fresh install of windows 7, 64bit home and added 4 gig of ram.

My battery life on maximum power saving setting(tweaked to be even better at saving energry here and there) is 3 hours and 45 minutes. With brightness set all the way to lowest position. This seems really poor. Running A09 bios(thanks for the tips to those two that helped straighten this thread out)

Anyone else out there?

 

I think it'd help if you stated what you were doing for those hours and minutes, by comparison.

I don't have a real burn down test ,on mine yet, but I've definitely gotten more than 4 hrs in the past on battery doing basically web surfing and document writing, with moderate brightness.

I've seen quotes in the owners forum of over 5 hours for sure.

 

Good idea, so I always just try to see what I can squeeze out of doing the least, word processing, email, light browsing(news websites). dvd disabled, bluetooth disabled, etc mmm really don't do much, going through organizing files I am working on, prep for work. The minimal tasks really. With the goal of seeing the laptop get the most out of the battery.

Also my laptop seems to run at about 60 Celsius average when doing these things. I have a non-powered targus branded laptop elevator thing. Giving it some room to breathe underneath even though the fans are at the back and intake on the side I think...

I would really like to 5 hours doing so little, or at least what I think is a little.

Thanks for the reply.

 

Might want posters to also state what BIOS is installed for comparison reasons.

 

Another good idea(sorry for making this poorly, I'me running A09 now.

 

Sorry to resurrect this thread, but i thought it would be just as good as starting a new one. I can't get more than 1 hour and 30 minutes currently. Even with the lowest brightness settings and power saver on and Dell's power saving options on in Quickset.

This is really unacceptable. Any ideas?

 

what kind of battery you got. I can get around 4hours of online video. You better ask dell to give you a new one.

 

According to BatteryBar, the battery has 63,830 mWh. I believe it's a 6 cell.

It says it only has 1.8% battery wear so I'm inclined to think my hardware is drawing too much power. Perhaps from CPU throttling, fan issues, or something.
