I have a Lenovo Z580 i5, 8GB RAM, Nvidia GT 630M.
I was running Windows 7 with good 5-6 hours battery but I've upgraded to Windows 8 (64bit) and ever since I'd be lucky to get even 1-2 hours running on battery.
I've tried upgrading all of the drivers on the Lenovo site and the energy management is set for longest battery life, I can't get to the bottom of why it is happening.
It seems the only option is to wipe the system and reinstall Windows 8 from scratch but I'd really rather not do that if possible.

I dont know how you were getting 5-6 were you using a word processor with no wifi and low brightness, because i only get 3h34m on Win7 according to battery bar on my z580 just browsing the internet, i have only a 6 cell battery do you have a 9 or 12 cell???

It is the standard Z580 battery, 5 hours is fairly standard - sounds like you have an issue as well or are just at higher use but:
During the LAPTOP Battery Test, which involves continuous Web surfing over Wi-Fi, the Z580 lasted 5 hours and 19 minutes. That's slightly below the category average for mainstream notebooks (5:24), but it still bests the VAIO E15's staying power (4:34).

I use an external optical mouse, and Kaspersky Antivirus that`s a battery killer, so maybe thouse are reducing my battery life, I have 0% battery wear.

Most people use the Win7 power manger on Win8 , i don't have Win8 so i don't know why, give it a go.
I get an estimate of 5h28m running in power saver mode, i was using balanced.

Been running this from 100% for less than 2 hours and I'm near 14% battery left! Very average usage, browsing internet, with back light 2 fn presses down from maximum.
