Battery life is based on testing using the Mobile Mark 2012 Productivity battery life benchmark test. For more information about this benchmark test, visit www.bapco.com. Test results should be used only to compare one product with another and are not a guarantee you will experience the same battery life. Battery life may be significantly less than the test results and varies depending on your product’s configuration, software, usage, operating conditions, power management settings and other factors. Maximum battery life will decrease with time and use.
