I have one of the new HP Envy 14's with the new Haswell CPUs. I could have sworn when I first got it I was getting about 6 hours of battery life. Now it seems fully charged it's less than 3 hours. Is this consistent with what anybody else is seeing?
I am sending you a link to Power and Battery click here. I am also including a document on "Using and Testing the ENVY Accessory Battery"click here. If you require further assistance, please let me know the exact model of Envy 14 and what operating system you are running.
The normal amount of battery life will vary with the programs running. The more programs, the faster the battery will discharge. Some programs require more than others. I am sending a link to a document on "Improving Battery Performance (Windows 8, 7, Vista)" click here. Please let me know if this has helped.
