Lenovo U400- Battery Life

Hey Guys,

 

I've bought Lenovo U400 I think a year ago and I've read some reviews about the battery life. They wrote that the battery life is 6 hour and 15 minutes, mine is 2 hourse and few minutes. I would like to know how it is possible.

CalciumKid,

Note that battery life varies depending on what brightness the screen settings are on, WLAN / BlueTooth / WWAN, external devices plugged in and the usage of the CPU.

Hope that helps. You can also try setting the PC to energy saving mode in Lenovo Energy Management too to improve battery life.

When my battery is 25% charged, it shows that I can use it for 40 minutes. That means that when its 100 % I can use it for 160 minutes.

CalciumKid,

Try turning off WLAN, BlueTooth, brightness settings to low then use only applications such as MS Word and you will see that the battery can last longer. You can try disabling Windows AERO too, that would reduce the need for the processor to make the Windows look pretty.
