A:Answer Thank you for the question. The battery life for the Pavilion 4m-dy0013dx is up to 8 hours and thirty minutes. It supports fast charge - approximately 50% in 45 minutes. Battery life is dependent upon your settings. Factors that affect battery life include the brightness of the screen, an active WiFi connection, and if you are consuming media, in addition to the number of programs open - when more programs are open, it requires more power for the laptop to keep the programs running. Lithium-ion batteries offer the highest capacities at the lowest prices. Handy if you want an inexpensive phone that lasts more than a single day between charges. Li-ion’s drawbacks include a gradual self-discharge. A Li-polymer is safer than Li-ion, important in these days of super-fast charging technology. These batteries also have a very low self-discharge level, so won’t go flat when you’re not using them. However, this comes with a higher price tag, a shorter life-span, and a lower capacity density. The lightweight nature of lithium-polymer batteries results in an overall better energy density per kg.
