I just replace the battery (PX03XL) and am wondering what I should expect for battery life. I realize it is an old laptop, approx. 9 yrs old, but I only seem to get about 3 to 3.5 hours of combined use before needing a recharge. Usage is mostly e-mail, web browsing and idle time. Keyboard backlight is off and display is approximately 70% brightness. Is my expectation for 6 to 7 hours unrealistic? Is 3 to 3.5 hours about right? Thank you.
What are the capacity of the new and old battery? Get HWInfo and monitor the average power draw over a full charge-discharge cycle and then compare it to the rated capacity to calculate the expected runtime.
