i7-640UM battery speculation.

Well, as title said. this a pure speculation.
Fujitsu have a Lifebook P770 w/ i7-640UM out. And the battery is 6 cell (10.8V, 5,800mAh). AW M11xR2 got 8 cell 63Whr, although input voltage is 14.8VDC the battery could be just 12VDC, but I don't know. According to TechRadar, this unit got 427 minutes of run time. I'm not sure how they test the battery life, but that look impressive.

Screen size is 12.1 inch (1280x800), so pretty similar to M11xR2, but no discrete graphics.

 

Thanks for posting this. Very interesting

And in conjunction with the thoughts of Seagate Momentus XT and how much that will drain. hmmm. I should have studied math more in school

 

Remember these numbers will be very similar due to the new Nvidia optimums technology of auto switching from Intel to Nvidia based card

 

i was very curious about this too-- does anyone have any speculation that they'd like to share about how optimus technology will affect the battery life of the R2?

Will it be switching that often?

 

I am going to assume only during heavy flash video's like 1080P and gaming.

 

I gonna say just gaming. Anything that use OpenGL & DirectX. Flash video could probably get away w/ Intel GMA HD. As this is new Intel redesign GPU that it suppose to be better than GMA4500 and most flash video are actually H.264 wrapped in flash. So, majority of the time Optimus will not kick in the discrete GPU.

 

Very true, but who knows. I agree and I hope that is the case!

 

From the page: Fujitsu = sleek. ROFLMAO. The piece of wood I use beneath my m17x is more sleek than that piece of junk.

I don't know what that sentence means "Most Core i7 laptops manage only average battery life, but the Fujitsu runs for an excellent 427 minutes. ". Most? How many laptops actually have i7 ULV CPUs?

On Intel GMA HD... have you actually used a laptop with an IGP ever? Flash videos rofl - Of course it's fine. It's not an iphone. The ONLY reason I use dedicated GPU is for gaming.

 

It is poorly worded, but I think they're trying to say that this ULV i7 gets way more battery life than a standard voltage i7, not comparing laptops with the same processor.

 

I'm sure with all the benchmarks that are being requested currently, I doubt we will have an accurate reflection of the i7-640UM battery life any time soon.

However, I am extremely interested in knowing if it will last very long. Nothing is worse than something that can't last long enough to get enjoyment out of it.

 

Acer Aspire TimelineX 1830T - Netbook Reviews

core i5-520um 8 hour battery life with 6 cell glad i got the i5!

 

good choice on the i5. would also been my choice, even if i had the cash for i7

 

I just read the article, and I still don't understand it. Here is the quote,

I think the 8 hrs is what is said on the brochure and not from a reviewer, since he doesn't even know which CPU exactly is in the laptop.

 

Here's a snippet about another laptop using the same processors, the Asus UL30Jt. "On display at the Consumer Electronics Show in Las Vegas, the Asus UL30Jt notebook features a 13.3″ 16:9 slim-type LCD display, Intel Core i7-640UM/620UM processor, up to 4GB of DDR3 RAM, up to 640GB 7200rpm SATA HDD, and up to 12 hours of battery life, all in a package less than one-inch thick."
I don't know how accurate that is, but it's a big difference from what the alienware representative said about 5.5 hours of battery life. Any thoughts?

oh and it also sports an 8-cell battery

 

i really hope it is closer to 7 hours of battery life

 

here's another:
Fujitsu P770 LifeBook Notebook Features:

These battery life estimations vary a lot

oh wait, but the lifebook uses a 6-cell battery

 

M11x R2 i7 Just arrived an hour ago - on first boot 67% battery already charged downloading 8 games on steam and web browsing on wifi and bluetooth mouse, on half brightness window battery estimate at current usage is 3hr 22mins (67%) remaining

 

that's bad news, right?

thanks for the update though m11ash

 

Is one of those games GTA-IV?

 

Its not bad news at all if you think about it!

 

I wish, I have the DVD retail version of GTA IV but not no external dvd drive
can't justify the extra $20 purchase from steam

Gonna see if I can DVD drive share from my macbook pro running on windows

 

Can't you just use your mac to read DVD and make an iso, then use something like SlySoft Virtual CloneDrive (freeware) to make virtual DVD drive?

 

I am hoping for at least four hours of battery life while web browsing, emailing, and social media. Also, do most of you leave all the fancy lights on all the time?

 

I'll look into this now GTA takes forever to install though so I'm not sure how long It'll take I'll post bench's as soon as I manage it

 

I only plugged in about an hour ago. on a full charge I'd say normal use at half brightness without B/T will last the Dell stated 5 - 5 and a half hours.

I'll test for defo with a stop watch tonight once it's fully charged. I'll follow that up with a full gaming session and give you batt results on that too.

 

Thanks so much!!

 

Thanks a ton!

That potentially reduced battery life is something that scares me, because this is still using ULV CPU and if it becomes power hungry then it will lose another advantage that R1 had.

 

Thank you so much, I am now a very happy zombie!

 

Update guy's I'm taking her off plug now. Fast Charge only 1hr and 20mins 7% to 100% while gaming on Batman AA

 

OK I found the GTA disks. How do I create the ISO? Also how can I transfer said ISO's over to my M11x? I only have a 16GB SD but I don't think I can transfer files larger than 4GB onto/off of it......... I haven't got a external HDD until I get back to the UK next week

 

Daemon tools Lite for mounting up ISOs. I used Nero to rip CD/DVDs. I believe to transfer files > 4 GB the drive needs to be formatted to NTFS file system instead of FAT32 which your drive probably is.

 

The Official ImgBurn Website For creating ISOS/

 

Cheers guys, started copying disk one using ImgBurn and I'm formating the Mem card too. Unreal you were spot on FAT32!

 

I just thought everybody already knew that FAT32 have 4GB limitation per file. As well as 2TB partition limit on older NTFS format. (Win7 don't have that problem though, XP does, and this including NAS volume) I'm sure this will creep up at some point as 2.5-3TB HDD start rolling out.

 

OK, she just shut down at 5%. 4 hours 24mins

I was running on half brightness, fairly intensive internet browsing the entire time. Bluetooth on, Wifi on, Bluetooth mouse. 30-45mins solid gaming with 360 usb controller. Read from/write to HDD @7200 for approx 110mins Finally it was on balanced power settings for the first 2 hours then I switched to High performance to game and write to HDD. Fairly good performance I thought not upto the C2D's however on power saving and turning off bluetooth I can easily see it lasting 5 1/2 - 6 hours

Hope this puts to rest some of the worrying on i7 ULV battery life for some folks

 

I personally can live with that battery life, thanks for the update!

 

Hmm I don't know. Window's normally way optimistic estimated battery remaining time has not gone much more than 5 hours on 100% battery, 1/2 brightness and the thing idling. The R1 I've seen 7-8 hours estimated. I seems it'll only go ~4hrs at best just doing regular Windows stuff..

 

Thanks Ash.

 

so you ran two hours on integrated then switched to the discrete graphics for the last two? that's pretty good

 

Anyone think there will be a significant difference between the i5 and i7 in terms of battery life?

 

the i5 will have one more minute of battery life than the i7.

 

I can also live with that battery life. That's a good baseline, and I'm sure that you'd get more if you needed to stretch it (ultimate road-warrior/traveller setup, low screen brightness, wireless/BT off, etc).

My current MBP gets less than that in Win7, even when I'm squeezing it, so this makes me happy.

+Rep for you, good sir!

 

For the time being, here is what I got.
Starting from 96% battery(unplug power)
both BT & wifi inuse, mainly web surfing and about 20 mins of lightroom3 including download picture from USB card reader (about 20 files). Brightness set at about 60-65% the whole time. Alienware LED(AlienFX) was left at default, Astral Aqua.
1 hour later, 72% battery, and now estimate about 3:18 left. Because of the way TurboBoost works, I think the estimate battery life will not be very reliable. Difference type of work will consume different amount of power.
UPDATE 1: another 1:50 went by from web surfing, now my battery sitting 33% with the estimation of 1:27 hour left.
Total battery usage sofar, 63%, almost 3 hours.
UPDATE 2: 45 mins went by, 15% remaining w/ estimate time left 39mins.
