Over the past decade, portable devices like laptops, tablets, and smartphones have become essential companions for people of all ages and lifestyles. Among these, laptops stand out as powerful tools that let you stay productive wherever you go. But when it comes to performance, battery life is a major factor, and high-performance tasks can drain it quickly.

Here’s a general breakdown of battery life depending on your activity:

1. •Web browsing or document editing: 8–12 hours
2. •Video streaming: 5–8 hours
3. •Gaming or 3D rendering: 2–4 hours, even on premium models

But have you ever wondered how much energy it takes to fully charge your laptop from a low percentage to 100%?

1. •Ultrabooks / Low-end laptops: 30–50 Wh
2. •Standard laptops: 50–70 Wh
3. •Gaming laptops: 70–100+ Wh

Battery Life by Laptop Type (On a Full Charge):

1. •Ultrabooks (e.g., MacBook Air, Dell XPS 13): 8–18 hours
2. •Standard laptops (e.g., HP Pavilion, Lenovo IdeaPad): 5–10 hours
3. •Gaming laptops (e.g., Alienware, ASUS ROG): 2–5 hours
4. •Business laptops (e.g., ThinkPad, HP EliteBook): 6–12 hours
5. •Chromebooks: 8–14 hours

Please keep in mind that actual battery life depends on factors like screen brightness, internet use, background processes, battery age, and capacity. Whenever possible, charge your laptop without interruptions for better long-term performance.
