Some brands of laptop have less than half the battery life promised by their manufacturers, a study by consumer group Which? has found.<\/p>\n

Only Apple’s Macbook Pro lived up to its 10-hour battery life claim in the tests, which included watching films and using the net via wi-fi.<\/p>\n

Models by Dell, Acer, Lenovo and HP came in with around half the advertised battery life.<\/p>\n

Manufacturers tend to test in “optimum conditions”, one analyst told the BBC.<\/p>\n

“Battery life metrics on consumer electronics devices such as laptops are typically measured in optimum conditions, which maximise performance,” said Ben Wood from CCS Insight.<\/p>\n

“There are lots of variables when it comes to real world use such as how bright the screen is and what applications you are using, which can have a major impact on battery performance.”<\/p>\n

‘Different mileage’<\/strong><\/p>\n

Dell also told Which? it was difficult to define average laptop use.<\/p>\n

“Every individual uses their PC differently,” it said.<\/p>\n

“It’s similar to how different people driving the same car will get different mileage depending on how they drive.”<\/p>\n

Which? tested a small number of laptops by seven different manufacturers.<\/p>\n

It found that:<\/p>\n
