A:Answer Battery life depends on how the laptop is used. After four hours of streaming a football game while casually browsing the web, I had 78% battery life remaining. I agree that the CPU runs hot - this is well-known with AMD CPUs. At 25% sustained processor utilization, my CPU temperature ranged between 80 and 85 degrees celsius, which while within specification, is somewhat concerning. The cooling system appears to do its job.
