An affordable laptop like the Acer Nitro 5 is expected to deliver 5-10 hours of battery performance for normal tasks like playing music, running ms office, reading pdf, or browsing. Still, it is not expected to last when playing games on the laptop except if it is plugged into a power supply. The average lifespan of Acer Nitro 5 is between 3-5 years for a laptop of its kind.
