Top 10 Best Laptops with Ultra Long Battery Life: 18 hours or more on a charge
Need ultra long battery life to be able to use your laptop all day and night without worrying about charging, then you have come to the right place. Today’s mobile processors and laptop components are becoming more efficient, so much so that it will last up to 18 hours or more on a full charge. Here’s what you can get.
To be fair, there are laptops that would last 12 to 16 hours on a charge, enough to get your though the day. But just getting you through the day is barely enough? Throw in another 4 to 8 hours to make it perfect. Long enough to cover your day through to the night. This is how you can truly leave your charging brick at home and for as long as you have your battery topped up the night before, you would never have to worry about running low.

Calling the LG GRAM 16Z90P ultra light (1.2kg) and slim (16.8mm) does not quite do it justice. It is certainly more than that. For one, it has a battery that can last up to 22 hours. The other big selling point is the quad HD display, at WQXGA 2560 x 1600 pixels on the IPS LCD panel, everything looks sharp and brilliant. 11th generation Intel Core i7 processor doesn’t disappoint and together with a generous 16GB RAM and 1TB SSD, it is fast and responsive. Plus the device passed seven industry standard military tests which can only be a good thing. If you are after something with an even bigger display at 17-inch, check out the LG GRAM 17Z90P. It still only measures 17.8mm slim and weighs 1.35kg with up to 19.5 hours battery life remarkable for a desktop replacement.

This Samsung entry goes neck to neck with Apple’s latest MacBook Pro 16 with a whooping 21 hours of battery life. The difference here is, one is a compact 13.3-inch convertible laptop while the other is a huge 16.1-inch desktop replacement. If you want a bigger system, go for the Galaxy Book Pro 360 with 15.6-inch display. It is still a friendly and versatile 2-in-1 machine but with a full size screen.

Next is the all-singing, all-dancing laptop from Apple that will put most professional desktops and workstations to shame. Based on the new M1 Pro or M1 Max, it will tear up any workload into shreds and eat them for breakfast before your morning alarm goes off. There is nothing the machine can’t do including lasting up to 21 hours on a full charge. However, this figure is derived from Apple TV app movie playback. For all day web browsing, it will last a respectable 14 hours on a charge. When you start throwing more demanding tasks at it, it will likely last a lot less, but that is what it is designed to do, run professional apps without flinching

Next, is our all-time favourite, hailing from 2020, the first MacBook Pro with Apple Silicone, the MacBook Pro 13. The design may be dated but so are many generations of MBP 13 based on Intel processor before it going back to 2016 with Touch Bar. While the bezel may not be as small as today’s 13.3-inch laptops and certainly no where near todays MacBook Pro 14 and 16, it is still relatively small. And, while the outside may look old, the inside is all new with a powerful M1 chip with unified memory, faster than all the MacBook Pro 13s before it with up to 2.8 times CPU speed, 5 times graphics speed and 11 times faster machine learning. But the most important of them all is it manages to do this with up to 20 hours of battery life to keep you going. The balance of four performance cores and four efficiency cores meant you don’t have to compromise on battery life.

More to a direct competitor of the Apple MacBook Pro 16, although nowhere as expensive (or fast) is the Galaxy Book Pro 15.6-inch. This full size laptop powered by 11th generation Core i7 processor still manages up to 20 hours of battery life. It is however the energy efficient Intel Core i7-1165G7 processor on Intel Evo platform with Intel Iris Xe graphics, 16GB memory and half a terabyte of SSD storage. Its lightweight at 868g, compact, slim as thin as a smartphone at only 11.2mm and sleek. Yet still manages to pack USB, Thunderbolt and HDMI ports with modern wireless connectivity like WiFi 6 and even 4G LTE cellular option. That’s not all, the huge 15.6-inch Full HD display is an AMOLED panel offering plenty of contrast and brilliant colour. If you like the laptop but couldn’t quite manage the asking price, try the Intel Core i5 option. Oh, and it sounds great too with AKG tuned audio, boots up and wakes up quickly and supports quick charging.

Scaling back to a more compact and slightly affordable machine is this 14-inch LENOVO Yoga Slim 7i Pro. It is a mouthful, I give you that. It is no slouch though. Powered by the same processor options for the Galaxy Book Pro 15.6-inch above, by that I mean the Intel Core i7-1165G7 or Intel Core i5-1135G7. While the screen may be small, it does have an edge over the rest here in that it is a 2.8K resolution display. That’s 2880 x 1800 pixels at 90Hz refresh rate and 400nits brightness. It even supports Dolby Vision with wide colour gamut at 100% sRGB in gloss finish. Matched it a pair of 2W Harmon Kardon speakers with Dolby Atmos and you have a match made in entertainment heaven. What really made it stand out from the crowd apart from the display is the 19 hours battery life. Again, you can have all of the above including the 2.8K screen and long battery life for cheaper if you pick the Core i5 model with 8GB memory and 256GB SSD storage.

Dell has made a name for itself in the ultra portable laptop market with the first Dell XPS 13. Many iterations later, it is still going strong with those super tiny bezels. Measuring just 16mm thin and weighing just 1.16kg, it is the favourite among executives and business users. One would imagine that with such small bezels, there would be compromises in the web cam department but no such luck. A lot of thought had been put into the design of its super small 2.25mm webcam including 4 element lens for sharper video and advanced noise reduction for better low light performance.

The laptop that started it all, the MacBook Air is a design icon in itself. It is also currently the only MacBook available in other than space gray or silver. And by that I mean gold. Like the MacBook Pro 13, the Air also received the first Apple Silicon treatment with the M1. The 5nm chip is so powerful, up to 3.5 times faster than previous generation yet so efficient that Apple have designed it without active cooling so you can enjoy a totally silent laptop. Not many can boast about the level of performance and thermal efficiency in the same line. To sweeten the deal, this is the most affordable M1 based laptop from Apple and it comes with Touch ID, Retina display and up to 15 hours of web browsing or up to 18 hours of content streaming on Apple TV app.

First entry from ASUS in our line-up. The ultra portable ZenBook UX425 is a 14-inch laptop with up to 18 hours of battery life. A second UX425EA powered by Intel Core i3 processor takes this further with up to 22 hours of battery life. A bit more about this later. The laptop is one of the slimmest and lightest 13.9mm thin and weighing only 1.13kg. With ASUS’s renowned solid built quality, ergonomic design with ErgoLift hinges that tilts the keyboard for battery typing angle and touchpad that doubles as numeric keypad with integrated lights, it’s a head turner no doubt. And, when you run low on charge, fast charging is supported and you can bring it back to 60% charge in 49 minutes.

So this may not be a ‘Pro’ level device like the mouthful Lenovo Yoga Slim 7i Pro but the amazing value LENOVO Yoga 6 has a secret weapon, it’s choice of processor. Using 5000 series AMD Ryzen 7 octa-core processor, the Yoga 6 with its 13.3-inch display will manage up to 18 hours battery life before you hit the wall socket. It is also a 2-in-1 convertible laptop making it the second such device with ultra long battery life. It’s amazingly great value with a glass fronted touchscreen that also supports Lenovo Digital Pen. However, our unit does not include this. The Yoga 6 is also available with AMD Ryzen 5500U processor and 256GB SSD storage at an even more affordable price.

Last but not least is this ACER Swift 3 with 13.5-inch Quad HD display, a pretty high resolution display for a laptop this size. While the faster Core i7 model only manages up to 14 hours of battery life on a full charge, the Core i5 model above is capable of up to 18 hours according to an online retailer. We couldn’t verify this with the manufacturer but the real world figure is likely to be less given that the high resolution display means the integrated graphics needs to work harder. Also from the same series, are laptops based on AMD Ryzen 5000 chip. Still, even at around 14 hours, the sharp display gets our vote. A case of compromising on battery life for a bright and sharp display.

Here it is powered by Intel Core i3-1115G4 processor, not the fastest but if you are not a demanding users, it should cover all the bases.
