When you buy a laptop, the <\/span>battery<\/b> is one of the key deciding factors. Depending on how you use your machine, your expectations for battery life and lifespan will differ. To help you understand what you can realistically expect from a battery, let\u2019s look at its power consumption, average runtime and lifespan.<\/span><\/p>\n

How power consumption is split inside a laptop<\/strong><\/h2>\n

Every component in a laptop draws on the battery in its own way. Some parts use far more power than others. Here is the average breakdown:<\/span><\/p>\n

    \n
  • The screen<\/b> is the main source of power consumption, accounting for <\/span>around 43%<\/b> of the total. It\u2019s therefore a good idea to <\/span>turn the brightness down<\/b> whenever you can.<\/span><\/li>\n
  • The <\/span>chipset<\/b>, the central element that handles data processing, uses <\/span>around 21%<\/b>.<\/span><\/li>\n
  • The <\/span>processor<\/b>, <\/span>graphics card<\/b>, <\/span>hard drive<\/b> and <\/span>network connection<\/b> make up the <\/span>remaining 35%<\/b>.<\/span><\/li>\n<\/ul>\n

    To <\/span>maximise battery life<\/b>, you should prioritise optimising the display and avoid heavy workloads whenever possible.<\/span><\/p>\n
