Which Lenovo Has Longest Battery Life

I have a T410s. Love it but despise the battery life, and I have the extra battery in the CD/DVD slot....

Any thoughts on what the longest running Lenovo laptop configuration is? I am looking for something that can go 6+ hours without being charged. Ideally don't want anything larger than a 14" screen though.

Is the longest running Lenovo option capable of powering a 30" display via a DisplayPort monitor? If not, any thoughts on what the longest running Lenovo would be that can power a 30" display via DisplayPort?

Thanks!

Well, there are MUCH longer-lasting devices out there, but will they do what you want them to? A fully loaded T410 has a lot more hardware capability than, say, an X100e. Also, how much battery life are you looking for? And what would you be doing while burning up that battery?

 

X200/X201 with 9-c battery would last 6+ hours easily

 

Microsoft Office Apps, sales reports, Citrix sessions, web browsing, and the occasional iTunes TV show.

6+ hours would be ideal. I used to have an HP 2730p with a battery slice on the bottom that would go 10+ hours but I am too addicted to ThinkPad keyboards to do another brand.

 

Thanks for the reply. Will it power a 30" display via DisplayPort when docked?

 

With the Ultrabase a 30" (2560x1600) display is supported with DisplayPort.

Note, the absolute best battery life would be held by an x200s or x201s with the 9 cell battery. The low voltage CPU and LED display should give a 10-20% increase in battery life compared to a comparable x200/x201 (although both are superb performers in this area).

 

for clarification, the X200 supports 1920x1200 over displayport where the X201 can support 2560x1600.   the X200 was limited by intel's implementation of displayport for that generation of processors.

 

I stand corrected. Thanks Erik.

 

It looks like the "s" models are discontinued. Is it a safe bet there will be a replacement for this model soon or should I just get the non S version?

Thanks - this forum is awesome!

 

The X201i is still current. Lenovo does not carry it online, but you can find it - with discounts, occasionally - at resellers, even newegg.com. As you can't configure-order at those resellers, you need to purchase an extra 9-cell battery, which I recommend if you want to be brick-free mobile the whole day.

I checked out the HP Elitebook: nice looking, but not as robustly built. X201 it is.

 

You will be fine with the non S version. While not exact science, I have had quite a few X200 and X200s and my experience is about 10% extra battery life with the X200s SL9400 over i.e the X200 P8600. I found the difference negligible and while the SL9400 1.86GHz is more than sufficient for most people's needs, it is always nice to have an extra 500 MHz of extra processing power for i.e. Video coding.

 

after using the x200s for couple of days, i find that it is not much better than a regular x200, especially if you ordered it with a WXGA LCD rather than the WXGA+.

 

I believe the longest running Lenovo is the T410 with the 9 cell main battery, 3 cell ODD battery and 12 cell slice battery for 24 hrs of battery life (supposedly).

 

The X301 supposedly can have up to a 10 hour battery life (using the 6 cell as the primary battery, plus one in the bay). However, the X301 is non-dockable.

 

For the X301, i never got 10 hrs when i had the 6 cells and bay battery, the best i could get was like 6 hrs.

 

I'm thinking this Lenovo has the longest battery life:

Wow, that sucks. I only have the 3cell with my X301, and I manage to get about 2 1/2 hours out of it. Looks like Lenovo lied about their battery life claim on the X301

 

the battery life varies, i can't really say whether they lied. Mind you when i quoted the less than 6 hrs time was with a normal platter hdd and with wireless on. So that should take about 1 hr off the battery time as compared to a SSD and with wireless off.

 

Both the X301 and the T410s rely on Li-Polymer batteries that hold much less charge than "equivalent" conventional Li-Ion batteries offered in the X201 and the T410, thus resulting in lower battery lives. In addition, there is no extended 9-cell battery option for either, so there's a disadvantage in battery life there as well.

 

What's the advantage of li-po batteries over traditional li-ion? What was the benefit to Lenovo to use a li-po battery. They seem to degenerate faster, take longer to charge, have a lower maximum discharge. Are they cheaper?

EDIT: nm, I see that they're lighter than li-ion batteries and more malleable, which makes sense in super thin laptops and cell phones etc.

 

@MAA83, have a read of this article.
