what kind of batter life do you get?

[mamamia88]

i was wondering what kind of battery life you get while running ubuntu? i currently am lucky to get 2 hours

That depends on many factors, i.e. click once on the battery icon near the clock, then click on Laptop Battery and look at the capacity. It might be that the battery is simply in bad shape, or that it does not have much capacity from the start. If you have got low capacity, you can try to do a few charge-discharge cycles in the BIOS (enter the BIOS, pull the plug, wait until the laptop powers off by it's own, then replug, go into the bios again, wait until it is fully charged, etc).

About 1.5 hours at best for me. :(

Without attempting to minimize power consumption: 3 hours and 10 minutes. If I lower screen brightness, disable dvd polling, lower hard disk access, use energy saving functions of wireless card and sound card, etc... I can get around 4 hours.

2.5 hrs

2 hours

On a laptop that is just over a year old that has been used every day, about 2 hrs. When I got it I got just under 4.

1 1/2 hours

About 2.5 hours for my 2 year old HP laptop. Though I did trick HP into giving me a brand new replacement battery in summer of 2008.

30 minutes. :(

I have a recalled Toshiba battery, and I wasn't even informed of the recall until 2 years after it ended. So now it lives on eternal AC power, with the battery only as a short back-up.

1 hour and 45 minutes. It is a pain.

Usually I can get about a week out of batter if it's refrigerated.

4ish hours. I trimmed Ubuntu down a lot, even switched to Thunar file browser instead of Nautilus. It's a netbook. I'm going to put ArchLinux on it today, just to see if it makes a difference, and to see what all the hoopla about Arch is.

A netbook is always going to have insane amounts of battery life. On an N270, the best way to conserve it is to not use a compositing window manager, because the GMA950 is probably the most power hungry piece there.

Darn it. I read the title and thought this was about fried fish.

I wasn't the only one then !!

[gymophett]

About 1.2 hours :(
Used to get 2.5 hours.

I get about 3 hours on my HP 9-cell battery before it says its critically low. I am having a problem though in correcting the callibration in ubuntu. The power-manager says that it is critically low (1% remaining).... I try to drain it all out like other have suggested but still manage then to get another 30-40 mins before it is totally gone, so I cant really trust what the manager is saying.

1 hour 20 min max

5 year old laptop (battery in bad shape).
