5 hours of continuous battery is fine. Not even a single minute more than 5 hours. I tested it several times. 8.7 hours of battery life as the Lenovo website advertises. Its too bad. Would have made sense at least 6 hours.
In terms of performance:
My system is an 8GB Core i5 1.9GHz CPU speed. It works perfectly fine with no problems. Open applications and heavy software which captures 5GB-8GB of space and are especially electrical engineering simulation software running much faster.
Very light weight computer.
