REVEALED: The laptops with the worst battery life
Laptops are meant to be mobile.
You’re meant to be able to use them wherever you like, without having to worry about your proximity to an electricity socket.
Except we all know that’s not strictly true for many laptops.
An hour or two tops, for many models, and your scrambling for your charger.
Thankfully, Which? have tested a load of laptops to see how their battery power stacks up against the bold claims of manufacturers.
And for many laptops, the results were not good.
Which? tested laptops by draining each one's battery from start to finish three times, each involving different tasks.
These included watching films or browsing websites on WiFi.
Lenovo Yoga 510, for example, claimed to have a battery life of five hours but was drained of juice after just two hours and seven minutes of use.
The HP Pavilion 14-al115na also failed, falling short of its advertised nine-hour battery life by a shocking three and a half hours.
Likewise, the Dell Inspiron 15 5000 could only run for just under four hours, despite its claim of a seven hour battery life, while the Acer E15 could only last for half of its claimed six hours.
Apple fans, however, will be pleased to know that the MacBook Pro 13 lasted longer than it should have.
While Apple said it would only last for 10 hours, the test showed it last for 12.
Run the test yourself and see if your battery lasts as long as it should.
If it doesn't, name and shame the maker on A Spokesman Said.
