Intel Haswell CPU promises 10-day battery life

Intel Haswell CPU promises 10-day battery life

Haswell not only promises to be a power-efficnet CPU, but will have system-wide power savings too. And without compromising performance.

Intel CEO Paul Otellini revealed that ‘We’ve already completed the design of Intel’s next generation microprocessor, Haswell,’ and made the claim that laptop charging will become a weekly or even fortnightly affair with Haswell technology.

Haswell was designed to enable a 30 per cent reduction in connected standby power over the currently shipping notebooks using our second-generation Intel Core microprocessors [Sandy Bridge], said Otellini, ‘But we can do more than that, we can do much better than that.

The plan is that not only will the CPU consume much less power than current CPUs, but that the system around it will also be heavily optimised for extending battery life. ‘We’re architecting a system-level power management framework that’s supported by efficient system design throughout the ecosystem that has the opportunity to reduce the platform power by a factor of more than 20 times over our current designs.

‘This means that we’ll be able to enable all-day usage and more than a ten-days, always-connected standby capability on a single charge.


That should mean that in typical use – a bit of work and a bit of web-browsing, and sleeping the laptop in between use – will result in only having to hunt out the power brick every week or two. It’s brilliant to get a month of use from one Kindle charge, but imagine only have to charge an entire laptop only one a week.

Even more impressively, Otellini said that ‘we’ll do and deliver all this without compromising any of the performance you’ve come to expect from today’s mainstream notebooks. The implications for the ultrabook are huge.

A fast laptop with a week or two of battery life? What’s not to like. We expect the Haswell CPU design to arrive in 2013 and to feature heavily in super-thin ultrabooks (presuming Intel’s latest laptop craze lasts that long).

Can’t wait for Haswell, or are you sceptical that Intel can deliver on that promise? Let us know in the forum.

I hate to be a pessimist but if haswell features 10 day battery life I will donate £100 to charity, and I never donate.

What are they doing about displays?

Let the hype begin! :D

My bet is slightly more efficient CPU tied to a MASSIVE laptop sized battery in order to get that 10 days. Seriously, car battery sized it'll be.

I really hope this is true. Regardless if it actually hits 10 days or not, it'll still a dramatic improvement over current standards. Too bad it's not out until 2013.

More to the point will they actually manage to include overcharge protection so that when you are plugged in to the mains that you are not constantly charging the battery and reducing it's lifespan.

He says one week of general use, So how long is that when left constantly on? you know how we normally measure battery life.

Intel always blow hot air when AMD is about to get some press, still don't like them for their anticompetitive practices.

Bulldozer FTW.

Let's not get too excited now. ‘more than a ten-days, always-connected standby capability on a single charge.’ A laptop's not much good stuck in standby all day. And they can only reduce the power consumption on the cpu. I believe displays are proportionally the biggest power drain in a laptop?
Now to wait for acceptable colour e-ink to make its appearance.

Just tidying up the thread after Snips' antics - I deleted posts that referenced that silliness to avoid confusing new posters - this reason is stated if you view the thread in the forum. Either way, it's no reflection on your comment, which was perfectly valid.

Please don't follow Snips' lead by posting the same phrase in multiple threads though.

I'd like to see a smartphone last a weekend first :D

What's "connected Standby"? Connected to what?

The mains ;)

I don't believe this is for Intel to meddle with, this should be down to the laptop manufacture not the chip maker

Ok noted :)

This should be really interesting, I do find it hard to believe that a laptop can last for 10 days but then I would consider myself quite a heavy user.

That's what I'm interested in. MMy laptop is plugged into the mains 99% of the time, so imporoved battery life doesn't interest me that much. But not having the battery die on me does.

I'm not that impressed, but that's because it's a rather difficult text, all in all.
A lot is left unsaid.

What does he mean...all-day use, OR ten day standby?
Ten days of all day use AND standby in between?

Just to emphasize: current netbooks give you ~6-8 hours of use (which could be considered all-day in a work environment) OR a week in standby (lowest energy saving mode).

Or this interpretation of the former:

So...20-30 mins of excel, some email reading, 2x 10 mins wikipedia, about an hour to hour and a half a day with standby in between.
Again, this is what a current netbook will do with three days between charges.

Hey Ipad-folks, how long does your battery last when using it for some light browsing about an hour a day?

nice idea, doubt it will happen,

what would be nice to see though is some inbuilt remote charging circuits and low cost remote charging pads, so that you can position the pads around the house in convienent places, attach it under a table top so that when you put the laptop on the table is will charge, have one on your bed side table, on a worktop in the kitchen etc

this added in with the jelly batteries http://www.bbc.co.uk/news/science-environment-14852073 could make interesting solutions

I am loving the sound of this!

TBH the headline for this news piece left me salivating - 10 days usage form a laptop between charges. Unfortunately it sounds like you will be able to get a "days worth" of charge from the laptop before it will nee recharging OR 10 days in standby (possibly including a couple bouts of checking email) OR roughly a weeks use if you only use it very periodically.

with tri-gate and the new 14nm die shrink, its really not that far fetched, of course in 2013 you'd expect performance of "new" chips = current mainstream chips :)

Ten days of all day use AND standby in between?

it means at zero standby and im guessing around 50% processor usage, it will last a day of charge, 100% usage, im guessing half that (maybe 6-12hrs between charging).

ten day standby, its what it implies im guessing , just to have some kind of idea compared to current laptops, most of the laptops at work that are left on stand by on a weekend (friday) are completely drained by monday. im betting intel's platform it not just about processors, but a whole bunch of technologies including the chipsets and whatnots.

im really not a negative and BS the company kind of guy but still I wan't to see a tech demo of this :) (if it holds Id really want to have one of those laptops for work)

wouldn't be surprised if it was a quad core running at like 400mhz at standby

Intel have said things like this before. The last semi-outrageous claim they made along these lines was that they wanted to develop a laptop that could last all day on a charge. Okay, they said it quite some time ago, but I'm typing this on one such laptop. Took them about 10 years to get it spot on last time so adjusting for all the previous work on projects like the Pentium-M and Atom, I think they'll probably not only manage that claim but get it mass-produced for the consumer within 5 years this time.

TEN-DAY BATTERY LIFE!*

* Assumes laptop is turned on, not in use, no USB peripherals plugged in, hard drive not being accessed, and LCD is off.
