Why You Shouldn't Buy a 15-inch Consumer Laptop

  • MORE

Pundits sometimes talk about the "wisdom of crowds," but just because something is popular that doesn't mean that it's good. Like the Twilight saga of the PC industry, 15-inch consumer laptops outsell all other sizes by a wide margin, but shoppers should avoid them like a sparkly vampire with control issues.

15-inch vs 12-inch laptop

According to research firm NPD, 68.1 percent of Windows clamshell laptops sold have 15-inch screens, dwarfing the more portable 14-inch (9.4 percent), 13-inch (2.4 percent) and 11-inch (10 percent) sizes. These 15-inchers also make up a plurality of 2-in-1s, grabbing 39.8 percent of that market, which is significantly more than the portions occupied by 13-inch (30.6 percent), 14-inch (8.9 percent) and 11-inch competitors (15.4 percent).

Laptop Sales

Mainstream consumers like 15-inch laptops, both because they like having a larger screen to stare at and because this size class usually gives you more performance for the money.

"Consumers value screen size above else and have for many years," said NPD analyst Stephen Baker. "For the amount of portability most consumers want, 15 inch[es] offers them plenty."

Unfortunately, many home users don't understand the benefits of having a laptop they can carry around and use unplugged. Most mainstream 15-inch laptops are too large to fit comfortably on your lap and are too heavy to lug around all day. The average 15-incher weighs a portly 5 pounds, which will weigh down your legs or the crook of your arm. By contrast, an average 14-inch laptop is 3.7 pounds or less, while a 13-inch system is usually 3.2 pounds or less.

Laptop Weight by Screen Size

Even if your laptop never leaves the house, you should be able to balance it on your lap (hence the name "laptop") or place it on a small table or nightstand. If you can't move your computer around the house, it's a compact desktop, not a notebook.

12.5 vs 15-inch laptop

If you really want the large-screen experience you get from a desktop computer, why not just buy an external monitor (or two) that you can connect to your laptop when it's on your desk? A 23-inch, full-HD display is much bigger than even the largest notebook screen, and you can buy a decent one for less than $150. Then, you can have the best of both worlds: a huge workspace when you want it and a portable computer when you need it.

If you can't easily move your computer, why are you buying a laptop in the first place?

You may have electric outlets in every room, but that doesn't mean you don't need long battery life. Remaining physically tethered to the wall makes your laptop a lot less convenient. Do you really want to be limited to the right side of the couch, the back end of the table or your partner's side of the bed, because those spots are next to the sockets? And what happens when your toddler or your dog trips over the cord, and brings your $600 investment crashing onto the floor?

Among all 15-inch laptops we've run the Laptop Mag Battery Test on since 2015, the average battery life is just 6 hours and 20 minutes, and that number drops to a mere 5 hours and 48 minutes when only sub-$600 laptops, the most common price range, are included. By comparison, the average 13-inch laptop lasts 8.5 hours on our test, while the typical 14-incher endures for 8 hours. 

Average battery life

Five or six hours of endurance may not sound that bad on paper, but it's important to note that our benchmark measures a low-power scenario, surfing the web via Wi-Fi at 100 nits of brightness (usually 40 to 50 percent). If you pump up the brightness, start multitasking or play games, your computer will die a lot sooner.

Laptop manufacturers and resellers deserve a lot of blame for the 15-inch laptop's misguided popularity. Whether you walk into a brick-and-mortar store or browse a website, you'll find a disproportionate number of low-cost laptops that have 15-inch screens.

According to NPD data, the average 15-inch clamshell laptop (with Windows) costs $391, compared to $622 for the typical 13-inch clamshell. However, the average 14-inch laptop, which is a lot more portable despite having just 1 inch less display space, runs just $243. For all laptop sizes, 2-in-1s cost a bit more, averaging $724, $565 and $773 for 15-, 14- and 13-inch screen systems, respectively.

 average selling price

However, if you know where to look, you can find a very portable laptop for well under $600. The Asus VivoBook E403SA has a 14-inch screen, weighs just 3.2 pounds, has an attractive aluminum chassis and gets over 9 hours of battery life. The Lenovo ThinkPad 13 starts at $584, weighs just 3.1 pounds and also lasts over 9 hours on a charge. Neither one has the fastest processor — although you can get the ThinkPad with a Core i5 if you pay extra — but both will be more than adequate for price-conscious shoppers.

Dell XPS 13

As you increase your budget, you can get even lighter and more powerful laptops, such as the 2.7-pound Dell XPS 13, which starts at $799 and lasts 14 hours on a charge.

Who should get a 15-inch laptop?

There are many people who really do need a 15-inch laptop, but they're not spending $400 on the latest sale item at Best Buy. Creative professionals, gamers and power-hungry business users need 15-inch or larger laptops because they require power-hungry components such as quad-core CPUs and high-end discrete graphics cards that just won't fit in a smaller chassis.

When you're a professional animator, videographer or engineer, it's worth carrying a heavier computer to get the performance you need and to be able to see more on-screen. You might really need to bring that 6-pound workstation on location when you're filming a movie or drilling for oil. But when you're in a profession that requires this kind of computing power, you or your company will be more than willing to pay premium prices for a laptop. You can even get a relatively light 15-inch laptop, such as the 4-pound Dell XPS 15, if you can afford to spend over $1,000.

Many gamers are also more than willing to spend thousands of dollars to get the kind of performance they need. Considering that some people still use bungee cords to carry their towers to gaming parties, a 5.5-pound laptop seems rather light.

Bottom line

If you're not a power user or a gamer, you should strongly consider a 12-, 13- or 14-inch laptop. The difference in weight and battery life between a 15-inch laptop and one with a smaller display is the difference between being able to carry your computer around the house (or around the world) and having to leave it on a table near an outlet at all times. And if you can't easily move your computer, why are you buying a laptop in the first place?

    Hi. What are examples for "power-hungry business users"? Where is the threshold?

  • Megan Says:

    I'll switch to 17 inch. I do always carry notebook with me and that's the reason to buy bigger screen - to enjoy advantages that only big screen can provide.

  • John Illinois Says:

    15 inch notebooks are popular because users like the size and buy them.

  • macbookpro Says:

    Have You ever actually tried to hold laptop on your lap? It gets way too hot for comfort, not to mention it's not very good idea at all as it's easy to accidentally break it this way. I treat my macbook with respect and I think everybody has got table in their house so it shouldn't be any problem.

    13 inch screen is small even with new retina display I like to watch films and not gonna ruin my eyes.

  • Anthony Says:

    Went shopping at Best Buy yesterday looking for a new laptop because my small laptop is too slow. My wife nearly refused to let me get another small laptop. She said "Don't get that little thing! The keyboard will have you all crammed up." I had read a lot f reviews and after looking at all of the Laptops we decided that the Samsung 9 was the best deal since the 15" was on sale for the same price as the 13". The 15" also has a bigger SSD hard drive and 16 GB of RAM. I did worry about the battery life of the 15" laptop since I hear it gets from 6-8 hours during normal use, but this particular model allows it to be charged via the USB as well as the power adaptor. I typically carry a portable charger for my phone when away from home so this could also be used for the Samsung 9 to extend the use of it. And at 15" it weighs less than 4lbs and is super thin. I'll try it for a while and see how I like it. My wife thinks I would regret it if I get the smaller one again because even she likes a bigger one.

    This is so true. I am a computer junkie, I buy a new laptop every 2-3 years. I have owned Sony, Toshiba, Hp and now a Microsoft surface pro. In the past I bought the big 17 powerhouse to play video games and while I love my last Beast the 17 inch fully loaded Envy I needed something to travel. I dropped down to a 12 in Surface Pro. Going from that big keyborad to this little thing has been a challenge but I am enjoying the mobility I have not. Plus for day to day activities this little jewel is prefect for me. I would never consider getting rid of my beast Envy but in love with new crush of the surface. :)

  • kurt weill Says:

    15" with digitizer is a great CINTIQ alternative.

  • DanielleV. Says:

    I had a 15 inch lenovo for 3 years and then a 17 inch lenovo for 1.5 years. The 15 inch one was perfect for watching shows while keeping the computer on a chair a few feet away and then for holding on my lap for other uses. The 17 inch one has been cumbersome and feels too big on my lap. I decided to buy an Acer 15 inch laptop because I have decided 15 inches is the perfect choice of screen size and ability to hold it on my lap for extended amounts of time. I also like that there's a few extra features available to the 15 inchers. I do not use a desk, ever. I got rid of my desk years ago and just use my computer from my couch. If I used a computer for work with design etc, I would want 15-17 inch laptop. My husband uses a fancy 17 inch dell for Civil 3D, infraworks, etc. 17 inches isn't even that bad, I just kind of like 15 inches better for my needs. So, there. LOL

  • Brian Says:

    Researchers now say that research firms don't know what they are talking about.....

  • NuNYaBiZiNeSS Says:

    The article is trying to bvadger 15" laptop users for choosing a 15 inch laptop. And then ridicules those who choose a 15 inch laptop and questions why and ends with a comment "because 14" laptop s are SO MUCH MORE PORTABLE"

    Sorry. Had to raise my voice there. Because a 15" weighing only 3/4 of a pound more than a 14 inch is gonna break my solid wood nightstand. Did anyone ever think that 15" laptops are the smalles that offer a near complete keyboard with numeric keypad? Not every 15 inch has this but no laptop under 15" has one, and that is not a power user feature. That is a convenience. Maybe a poor write up but more of a personal opinion with some hints of cirticism towards people who still choose a 15". The article clearly showed the piece of the market 15" laptops have. Well, there's a good reason for it. I think everyone else who responded clearly explain why. Let the people choose. Not the writers

  • Connor Beckerle Says:

    This article is terrible. First, it states very incorrectly that 15 inch laptops are not portable at all ("5 pounds, which will weigh down your legs" is a ridiculous statement, as is the notion that the extra 2 inches of screen size will prevent it from resting across your legs). Second, it takes an unnecessarily condescending tone; I would have realized by now if I was somehow unable to move my laptop from my desk. A little nuance would have gone a long way in some of these paragraphs.

    I think there may have been a valid goal behind this article, but it was obscured by its flaws. Or maybe, like me, people like looking at two documents on their screen at once. Who knows?

  • Chirpy Says:

    I carry around a 15inch Thinkpad at work. I like it. Maybe I'm super strong but 5 lbs is not heavy to me at all.

    I want a personal Thinkpad that bends like the Thinkpad yoga. But guess what? There's no such thing 14 inches.

    Well I think the 14 inch size is a good move for some it would suck for me.

  • Khann Says:

    LOL. LOVL. This article makes no sensen whatsoever and I cannot believe this article was written this year. I have a huawei phone that has a 6.8inch screen and yes people laugh when I hold it up to my ears but I never struggle to watch videos when commuting. I'm thinking of biying a 17inch laptop soon because I like to work in bed and I haven't yet figured out how to use a laptop and a monitor in bed. And hooking up to my TV is not only ridiculous but out of the question.

  • Storia Direct Says:

    Inappropriate link. There is no relation to what Storia Direct sells. They manufacture laptop tables, not laptops so this is very technical post. Please add a new one.

  • Robert Harrison Says:

    Great article. I am archiving all the "why you, why you shouldn't" articles for review before I buy my next PC. They are so logical. Thanks!

  • 3000_Tonnen_Koala Says:

    This article is actually really good and to the point. The only thing that I will never understand is why a 15 inch 6 pound machine doesn't have an 80Wh Battery and a Core M Processor. That way you would have a large screen, and 20 hours of battery life.

  • Gerd Kramer Says:

    I am getting sick of staring at my 10in Nexus 10. I will buy a 15in laptop soon. Avram, as sturdy as you are build, I am sure you could carry a 15in around anywhere in my 2 storey house. I can, at age 74, with heart and lung problems .

  • William Says:

    @Eric Ouellet The article makes a lot of sense if you care about having the best computing experience possible, but the point is, most people don't. They see having a laptop or computer as a necessary evil. The author of this piece is a tech geek so doesn't really get it.

  • Eric Ouellet Says:

    I like when somebody tells me what I should buy for my needs. It's nice to see peoples telling what to do or not to do when they even don't know you and what you will do with your laptop.

  • William Says:

    From what I have seen, casual users want a computer they can hide. Why give over a section of your house to a massive screen and tower? They want to type out some word letters once a month and then put the thing away out of sight. They don't care about portability or battery life or raw power. And lets face it, bigger screens are just more comfortable to look at. 17 inch machines start to become unwieldy, even to get out of the draw to put on your desk. I totally get why 15inch is such a popular size.

  • Mike in Oceanside Says:

    Wow, when did Americans get SO wimpy we can't handle 5 pounds? REALLY?

  • Antonio Says:

    Yeah right. Dell XPS 15 and MSI GS63VR are slim, small and powerful, while under 4lbs. Many 7th gen 2-core 15" ultrabooks are even slimmer and lighter, altho less powerful. This article would make more sense if it were written 3 years ago

  • Person Says:

    There's good reason for the popularity of 15inch models; they tend to be more powerful (as noted), and a 13 inch screen starts to seem pretty small when your laptop is sitting a couple feet away on a table. Also, if you're unable to carry a 4 or 5 pound object room to room, you should probably be getting more exercise.

  • SouthFloridaWireless Says:

    "If you're not a power user or a gamer, you should strongly consider a 12-, 13- or 14-inch laptop."

    Just try that 12" laptop before buying. To me it's fine for browsing but useless for work.

  • Plugged In Says:

    Most laptops use bottom vents to stay cool. Never ever use a laptop on your lap.
