Windows 7 users have been complaining about battery problems on Microsoft's official forums since June of last year, months before Redmond pushed out the full, public release Windows 7. Some complain that their battery life has dropped significantly, while others say the OS is suggesting they go as far as to replace their battery with a brand new one.
One user named tigger1962 says,
"Until yesterday it used [to] state that I had 7 hours battery life after a full charge; today after a full charge, it states that I have 4 hours left. I've only had it on now 15 minutes and my charge has now gone down to 2 hours 24 minutes."
Reverting to Windows XP or Vista doesn't work and neither does charging the laptop while it is off or booting to another OS to charge.
