DVT6QE Battery Life

Couldn't find it in the 400 page thread.

How long is the battery life for the dv6 qe with a 6770m and the upgraded 6cell battery? Is there a noticeable difference between that and the SE? Thanks guys and gals. Was gonna order the SE tomorrow but the coupon expired so I probably am gonna get stuck getting the QE for 100 bucks more. But if battery life is well below 3.5 hours I'll need to rethink it. Or consider paying 60 bucks more for the SE?

 

The QE > SE in every way. I'd say getting the QE is totally worth it. Sorry that i don't know much about the battery life though... I heard it's quite long.

 

I have the DV6QE with the standard 6 cell battery. I can get about 3.5+ hours from it if I switch to the Intel graphics. Compared to other laptops with a quad core in it, it isn't that bad. The upgraded battery should get a little bit better performance. The battery life with the ATI graphic on is significantly reduced. I haven't done any real testing, so take my information with a grain of salt.

 

3.5 hours? That is kind of disappointing. I thought that SB was supposed to offer a significant improvement to battery life. My dv6z with an AMD quad core could get 3.5 hours on normal use

 

According to this graph from Andandtech, the i5-2520m (DV6t SE) vs. the i7-2820qm (DV6t QE), the dual-core will do 10% better in battery life during internet usage. Battery capacity has been taken into consideration.



However, when doing other more heavy tasks such as H.264 playback, the dual-core i5-2520m battery life outlasts the quad-core i7-2820qm by 30%. Battery capacity taken into consideration.

Yeah I think I'll still order it... I know neither computer will get the 5.7 hours HP claims, but I figure that being able to get 3.5 at least should be solid, and I'll just keep it on intel mode unless I'm doing gaming or something intense, and in that case the QE + 6770 should run stuff very well. Besides, I don't plan on playing BF3 on an airplane.

 

I haven't tested it because I haven't gotten my notebook yet. But has anyone (can anyone) test how disabling 1,2,3 cores on the Quad-core i7's affect battery life? Either through run > msconfig (windows) or BIOS?
What about disabling Hyperthredding (probably not much with this)?
And finally limiting maximum processor state to 60%, 50%, or maybe even lower?
(some of these suggestions might actually have no effect or negative effect (lower processor state, longer time to carry out commands) but I haven't ever had a multi-core laptop to test it with.
And by the way, what about disabling the fingerprint reader, the ethernet port, and anything else I'm leaving out?

And some of you might find this annoying, but I would also close all unnecessary apps, processes, use disable Aero Desktop and setting the screen dim and to turn off after a minute of non-use.

I want to see what the MAX battery is and then start checking for realistic settings...

 

I did a simple test of my DV6-6091 with standard 6 cell battery. I got about 4.5 hours of light/real world usage. This includes thing like music, videos, and web browsing. 4.5 hours is not that bad for what I was expecting. (I hear that other i7 laptops get about ~2-3 hours) Hope you enjoy yours.

Edit:
This test was with the ATI GPU off and screen dimmed to about 40%

 

That's pretty good! :yes:
When you hover your mouse on the battery, does it just display a percentage? I know that HP laptops (their batteries specifically) don't give the estimated time. I know many people argue that it's not a good indicator, but I would have to disagree, of course it changes depending on the things your doing!
And I would like that simple indication as opposed to installing some other software to do it for me. Anyone know of any good ones in case I really want it?

 

So I just started using the Batteries and (since they aren't exactly calibrated, I can't guarantee 100%) but with the 9-cell on integrated graphics, fans low, (look at files on the computer) I got an estimated 10+ hours. With Wifi on and browsing it gets about 8-9.
Will keep you guys posted!

 

From experience, 8.5 Hours max (9-cell).

 

I tested the max battery life with the 6-cell battery. At night, I left my notebook to download torrents (on wired LAN Internet, wi-fi turned off) on battery with the screen closed. I noticed that the notebook went on hibernation at critical low battery level near about 4 hrs. later.

 

That's pretty cool. I was looking at your Signature, and wanted to ask is there really a reason you added a 4GB Memory Module that is better than stock? Wouldn't the stock limit the better one?

 

I don't get what you meant by better than stock. Both memory modules are of 1333 MHz and are working fine in dual channel mode without any trouble so far.

 

Oh sorry I assumed it was more than 1333.

 

i don't think this is a good comparison for a battery life in any stance imo.

but i do thank you guys for the information on this thread.
