Battery duration on X60 vs X60s

[thomas1977]

Hi,

I want to buy a Thinkpad and I am a little bit confused about the time the battery will hold its charge. I cant find a link, but i believe i have read something like that:

X60 up to 4 hours
X60s up to 3.5 hours (both with 4 Cells)

But the X60s has a LV processor, so it should hold longer? What has the most time without plugging in? X60,X60s,X61, X61s?

thanks alot
thomas

The best battery life is achieved on X61S. I've gotten close to 8 hrs on an extended one.

A lot of factors effect the battery life. Screen brightness, the CPU load, whether the WiFi is turned on, to name a few. Without knowing what the settings are during the test, it's kind of hard to say. Since the X61s uses the LV C2D it should get better battery life. The one I saw last summer went about six and a half hours with WiFi on and the screen dimmed to about half.

+1 with FredGarvin;

I have an extended battery (the 8 cells one) and about a year ago I did this screenshot (NOT retouched in any way, just cropped the pic)



This has been taken right after the machine started. I recall killing a couple of process, but none of the TP native software. The screen had to be toned down to minimum, no wireless or bluetooth. Of course she was idle at the time. The real total running time was about 7:30 hours while coding some Java under Eclipse and having a couple of ebooks loaded.

With the Wifi enable and browsing the web, she last for about 5-6 hours of autonomie.

My advice is when you get your machine (regardless to the brand) disable as many unused processes/devices as possible: I don't use bluetooth on a regular basis, so I have it disabled. It makes a hell of a difference on the autonomie.

Consider the 8 cells battery if you are on the go. Compared to a T serie of the same generation you will never have to carry around a power supply for a full day working (5-6 hours continuous) as long as you don't plan running heavy application.

Thanks for response. I now bought a nice X60s with 8cell, which holds for 6 hours with full wireless and bridness. I wonder, how much it is with new L8100 CPU on X61s. I am really impressed and quite happy Would buy it anyytime again.

The X61s has a shorter rated life because the battery it comes with is the "slim" which has a smaller capacity than the X61's "enhanced" battery. I couldn't get it the battery estimates to stay constant enough to compare well, but I would say the X61s could do about 1/5 bettery on life.
