Example of "real world" battery life

[vtan]

I thought I'd share my experience with battery life on the W510 over the past few days. I have a unit with the keyboard. Autobrightness is OFF and I set the screen to about 25%, reasonably bright under the office lights and plenty bright in any environment dimmer than that. My wifi and bluetooth are always on for network connectivity and a bluetooth mouse. So, I left the W510 charging Tuesday night then:

Wednesday
- did email and read for about 40 minutes first thing in the morning once I got to work
- had 4.5 hours of meetings throughout the day where I used Onenote in all meetings and opened various spreadsheets and docs in one meeting
- read news for about 40 minutes before supper
- watched a 45 minute TV show streamed from my Plex server
- read my tech blogs for about 30 minutes before bed
- did NOT charge the unit overnight

Thursday
- read for about 20 minutes once I got to work
- 4 hours of meetings throughout the day where I used Onenote
- read news and tech blogs after supper, bit of email for about 40 minutes

Battery check:
- at 56% (100% for tablet, 2% for keyboard)

Friday
- did NOT charge the unit last night
- read for about 20 minutes once I got to work
- updated my jounal (Onenote) for about 30 minutes
- a 45 minute meeting where I took a few notes

Battery check:
- at 46% (83% for tablet, 0% for keyboard)

So, I'm pretty darn confident that the W510 would be able to last a third full day at work ... but I don't have any more meetings today (fortunately or unfortunately?) to confirm that theory. =)

Certainly sounds better than the W500. I can get 6-7 hours from its battery.

i do not have the keyboard dock so i cant really compare but with just a tablet i think it's just about 4.5 to 5 hours of full usage (i mean full, without any idle moment. The screen is always on). This is with 25% of brightness and same thing with you (auto brightness off)

forgot to mention that's with 3G external modem and a bluetooth mouse

with just wifi (and off bluetooth) i can get about 6 hours

and without wifi i can get about 8.5 hours
