They have become very popular thanks to their <\/span><b>compact format, great mobility<\/b><span style=\"font-weight: 400;\"> and the ease of getting a powerful configuration at a more affordable price compared with fixed systems.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">However, after a few years of use, a laptop battery starts to show signs of fatigue, which pushes users to treat their device like a \u201cdesktop PC\u201d or to <\/span><b>constantly hunt for a mains socket<\/b><span style=\"font-weight: 400;\"> to recharge.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Battery life is a crucial buying criterion, coming right after raw performance. Most users expect their battery to last long enough to <\/span><b>cover at least 8 hours of work<\/b><span style=\"font-weight: 400;\">. This runtime depends on several factors, including the physical capacity of the battery, the workload demanded of the system and the laptop\u2019s own power consumption.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The good news is that the market offers laptops that meet and even exceed this expectation. Our league table highlights these standout models. To stay as objective as possible, we based our ranking on two types of tests: those that push the battery to its limit and those that simulate power\u2011saving conditions.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Power\u2011saving tests are considered the most reliable for comparison because they are carried out in standardised conditions: full battery, Wi\u2011Fi off, aeroplane mode on, screen brightness at 50% and background apps disabled. Only the playback of local video content draws power.<\/span><\/p>\n<div style=\"padding: 80% 0 0 0; position: relative;\"><iframe style=\"position: absolute; top: 0; left: 0; width: 100%; height: 100%;\" src=\"https:\/\/player.vimeo.com\/video\/1147656975?autoplay=1&amp;loop=1\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"> <\/iframe><\/div>\n<h2><span style=\"font-weight: 400;\">Top 5 laptops with the most impressive battery life<\/span><\/h2>\n<h3><span style=\"font-weight: 400;\">MacBook Air 2020<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">Whether you are a Mac (iOS) ecosystem user or not, you have to admit that Apple laptops are consistently ranked among the <\/span><b>best for battery life<\/b><span style=\"font-weight: 400;\">. Native apps are specifically developed to reduce power consumption, which helps the battery last longer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The MacBook Air 2020 comes with a 49.9 Wh (4379 mAh) lithium\u2011polymer battery. The manufacturer claims a theoretical battery life of around 11 hours.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Because runtime is directly linked to workload, web browsing, media use and gaming all tax the battery differently. In maximum load tests, the machine lasts around 8 hours.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The results of the so\u2011called \u201cpower\u2011saving\u201d tests are outstanding: <\/span><b>the battery reaches 29 hours<\/b><span style=\"font-weight: 400;\">. That\u2019s enough for continuous film or series viewing over an entire weekend without needing to recharge. This record is explained by Apple\u2019s optimisation, which ensures <\/span><b>very low power consumption<\/b><span style=\"font-weight: 400;\"> from the processor during video playback.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Asus ExpertBook B9450<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The ExpertBook B9450 is fitted with a 66 Wh (4280 mAh) battery. This Asus laptop is also notable for its <\/span><b>clean design, light weight and comfortable user experience<\/b><span style=\"font-weight: 400;\">, making it an excellent choice for working on the move.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In heavy\u2011use tests, the battery lasts between 9 and 10 hours.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Against Apple, Asus positions itself as a serious rival: the ExpertBook B9450 manages around <\/span><b>28 hours of video playback in power\u2011saving mode<\/b><span style=\"font-weight: 400;\">. The choice between these two champions will mainly come down to your preferred operating system (Windows or iOS).<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Dell Inspiron 14 7000<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">The Dell Inspiron 14 7000 uses a 4\u2011cell 52 Wh (6840 mAh) battery, with a manufacturer estimate of 8 to 9 hours. Independent tests place it just behind the MacBook.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Under heavy load, battery life is around 7 to 8 hours, which provides <\/span><b>solid coverage for the working day<\/b><span style=\"font-weight: 400;\">. In minimum\u2011load tests, the battery reaches <\/span><b>21 hours<\/b><span style=\"font-weight: 400;\">, which is more than enough for unplugged multimedia use.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">Dell Latitude 9510<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">This model is available with two distinct battery configurations: a 4\u2011cell (52 Wh) and a 6\u2011cell (88 Wh). The two are not interchangeable. The Latitude 9510 is often cited for its <\/span><b>extremely long<\/b><span style=\"font-weight: 400;\"> battery life.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In maximum\u2011use scenarios (browsing, video calls, streaming), tests record around 14 hours.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In the \u201clight use\u201d battery test, the laptop reaches <\/span><b>24 hours<\/b><span style=\"font-weight: 400;\">, which is very impressive. It\u2019s worth noting that these figures come from tests of the more powerful 6\u2011cell battery. It\u2019s reasonable to expect the 4\u2011cell version to be closer to the Inspiron 14 7000. The two Dell machines therefore share third place.<\/span><\/p>\n<h3><span style=\"font-weight: 400;\">HP EliteBook x360 1040 G7<\/span><\/h3>\n<p><span style=\"font-weight: 400;\">After being less visible on the market for a while, HP is back with some strong performers. The EliteBook x360 is equipped with a 54 Wh (7012 mAh) battery. It can last around 17 hours under heavy use. In favourable conditions, it reaches about <\/span><b>20 hours<\/b><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">As mentioned earlier, standardised tests are the best indicator of real\u2011world battery life. Despite its excellent runtime, the HP EliteBook x360 comes in at the bottom of this list.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Key points for choosing the right laptop<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Your final choice depends on a <\/span><b>careful look at your daily routine<\/b><span style=\"font-weight: 400;\">. If your life means constant movement, travel and a permanent need to stay connected, any of the models listed will be an excellent investment.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">On the other hand, if your work is mainly desk\u2011based or you have easy access to power sockets, a <\/span><b>more affordable option with shorter battery life<\/b><span style=\"font-weight: 400;\"> may well be enough. The choice is purely about what you need the laptop to do.<\/span><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In recent years, we\u2019ve clearly seen laptops take over from desktop machines.
