Actual Time on 9 Cell Battery

Hi all,

Just bought a XPS 1210 with a 6 cell battery.

I get about 3 hours charge before I have to plug it in.

Anyone know just how much charge time you get on a 9 cell?

Thanx in advance for any info.

 

Without sounding obvious, it does depend on how you use the laptop. Watching movies, rendering graffics, playing games, all eat up the battery much faster than Listening to music or doing word processing. But, on my 6 cell battery I do an average of about 2-1/2 hours, and on the 9 cell, about 4 to 4-1/4. I have have, however, streched my 9 cell to almost 6 hours before (but only with light use). I hope this helps.

 

Should be able to get 5+ hrs off the M1210 w/ the Nvidia 7400 and 6+ hrs with the Intel 950GMA card. Dell claims up to 7hrs, with Integrated graphics.

 

I get over 4 hours on the 9 cell with screen brightness reduced slightly, Wi-Fi on, and lots of browser windows open. I can easily get over 5 by turning off my Wi-Fi and turning my brightness down more. My M1210 has the T7200 and the Nvidia 7400.

 

I get 6:30 minutes with my 9 cell.

 

the battery time reading is just an estimate, the only way to get a true guage is to charge it full, and time the drain doing various activities

with the gf7400 set in performance, and using a spare monitor to view the batery meter while looping 3dmark05 it reads at 2.2 hours, when in reality it cuts out just under 1.5, thats with the 6 cell

 

Thanx for all of the info.

I will get one as soon as I can.

 

With my T7400, 2GB Ram, Geforce 7400, 160gb 5400rpm drive running Windows Vista (a.k.a. Very Powerhungry system)

I get 5:00h with brightness turned all the way down, max power tweaking in terms of graphics and stuff, and bluetooth and wifi off. (Drains at about 15-17whr)

With brightness at max, Wifi and Bluetooth on, and High Performance selected as my scheme, I get 2:30h (Drains at about 30-35whr)


This is as calculated by BatteryMon which is very accurate

Ofcourse with Integrated Graphics, Less Ram, Slower CPU, and running XP, Battery life will go up to what people state above, my case is basically a worst case scenario. (unless you get a T7600 which would shave off another few minutes)

 

Hi,

How do you make the screen dimmer? I can't find how to do that.

Thanx

 

FN + Up/Down keys (you should see the blue sun/light symbol)

 

Changing the brightness does help the battery life. I have noticed by just going down one setting, that it increases my battery life quite a bit.

 

I get more than 6 hrs, prehaps 7 hrs or more in my D420 w/ minimum brightness and wifi on, w/ 9 cell battery.
- NHC turned on...
- turned off unnecessary software and services
- New laptop and battery..

 

bottom line, your battery life can be either very long or very short depending on how you use it and what you use it for, general productivity ( office work) with low brightness , bells and whistles turned off and low disk usage could net you almost a full days work, playing games or encoding large video files, or any task that pushes your systems capeabilities, its going to be short lived, those activites are best done next to an outlet anyway, the only thing I really wiah they would change on the m1210 is a modular drive bay, so you could switch to a spare battery on the fly, as it is, even if you have four batteries, you either need to be plugged in to change them, or you have to shutdown and restart everytime
