Shopping for a new laptop can be expensive. Although the $699 MacBook Neo and XPS 13 try to make a premium-feeling laptop more accessible, Lenovo’s IdeaPad lineup does the same. It bridges the gap between the best budget laptops and those that aren’t — especially if you’re looking for a no-frills computer for school or office work.
The new entry in the family, the Lenovo IdeaPad Slim 3i 15 (2026), continues that tradition. It is a great laptop with a spacious 15-inch touchscreen, solid everyday productivity performance from Intel’s new “Wildcat Lake” processor, and decent battery life to get you through the day.
I loved this IdeaPad, as it comes at a tough time, when laptop prices are always on the rise. At the sale price of $799, that makes it even more of a great laptop. But at the full price of $1,299, it isn’t a chart-topper among similar competitors when it comes to the design and its keyboard. It will, however, help you get your job or assignments done if you need a new dependable laptop.

Lenovo IdeaPad Slim 3i 15 (2026): The ups
The Lenovo IdeaPad Slim 3i 15 (2026) has a lot going for it, including a vivid 15-inch display, excellent performance, and long battery life.
A big and bright 15-inch touchscreen
The top reason I love the Lenovo IdeaPad Slim 3i 15 (2026) is its large 15-inch 1920×1200 display. As a lab tester, I am constantly digging through spreadsheets, so this laptop really made my job easier. I can stack multiple windows side by side, including Slack and my Google Chrome browser. I didn’t have to connect to the portable monitor on my desk in our test lab, as I usually do. This helped free up my desk space for the multiple devices I tend to test on a day-to-day basis.
Switching through all of my work was smooth, thanks to the 120Hz refresh rate and the ability to touch and scroll the screen with just a few clicks. This 120hz touchscreen is something the MacBook Neo doesn’t have.
While the MacBook Neo and the XPS 13 might be cheaper than the IdeaPad Slim 3i, they also have smaller screens. On those systems, you’ll likely need to adjust scaling in Windows 11 or macOS to get a good view. That makes everything look smaller, so it is nice not to have to deal with that on this big-screen IdeaPad.

The screen gets pretty bright, too, reaching 408 nits in our lab testing. It also covers 116% of the sRGB color gamut and 82.2% of the DCI-P3 volume. That puts it 50 nits below the MacBook Neo, ahead of the XPS 13, but behind the MacBook Air in terms of brightness.
As someone who has used and personally tested all those laptops, it’s not something you’ll likely notice in everyday use. The screen still shines bright. When I watched a replay of one of my favorite cartoons, Disney’s Hailey’s on It!, the brown in her face looked really rich, and the colors in this animated universe really popped and came to life. It might not be OLED, but this display is still a real treat.
Productivity performance from Intel Wildcat Lake
Intel’s new Wildcat Lake processor delivers exactly the level of performance most students and office workers need. You can already find it in the cheaper XPS 13, but the IdeaPad Slim 3i 15 is one of the first 15-inch laptops we’ve tested with the higher-end Core 7 version of this chip. For productivity, the Intel Core 7 350 delivers with a 2,669 single-core score and a 7,827 multi-core score in Geekbench 6.

Even though our lab’s benchmarks might show this IdeaPad trailing just slightly behind the Windows-powered competitors, it is still good enough for $799, since most people who don’t want a laptop for raw performance at this price. The IdeaPad had no issue juggling media-rich tabs like Reddit, YouTube, and the Tom’s Guide and Tom’s Hardware homepages. Even with around 20 browser tabs spread across Edge and Chrome, the system remained responsive.
I even enjoyed playing some Microsoft Store games like Solitaire in the background during my lunch break. I also played Shadow of the Tomb Raider at 1080p, with a few settings tuned down. This game is pretty old, but it is known to stress the CPU — so it’s surprising to see this kind of performance from a laptop that isn’t meant for gaming.
You’ll still have to keep expectations in check, though, as this is not a laptop for video editing and gaming, as the 9:22-minute result our lab got when encoding a video in Handbrake shows. For that, the MacBook Air 15-inch, which is priced the same as this laptop when not on sale, might be a better buy if you can switch to MacOS. For something cheaper, you also might want to consider Lenovo’s own IdeaPad Slim 5x, which has higher multi-core performance for more demanding tasks beyond everyday productivity.
Strong battery life
Having used the Lenovo IdeaPad Slim 3i 15 for work, I found the battery life good enough for my needs. Thanks to the power-efficient Wildcat Lake chip inside this laptop, I was able to get through my full workday on a single charge with the screen at a comfortable 44% brightness. I even had about 40% of battery life left when I came home to finish off the day streaming YouTube videos and browsing through my social media apps.

With a result of 10 hours and 33 minutes on our lab’s web-browsing battery test, this laptop falls behind its competitors and comes nowhere near the 15 and a half hours achieved by the MacBook Air. It also isn’t quite up to the Arm-powered IdeaPad Slim 5x sibling. However, 10 hours and 33 minutes is still a decent result, considering the large 15-inch screen and the 120Hz refresh rate, which consumes extra power.
Our lab’s synthetic battery test is also fairly demanding on the laptop, since the screen is set to 150 nits and the laptop auto-browses through websites, streams video, and runs OpenGL tests until the battery is exhausted. In the real world, you shouldn’t have a problem living away from your charger.
Lenovo IdeaPad Slim 3i 15 (2026): The downs
While there’s a lot to like about the IdeaPad Slim 3i, it’s not perfect
Plastic chassis
For $799, this laptop will have some compromises that many budget Windows laptops in this range that predate the aluminum XPS 13 and MacBook Neo frequently carry. One of those is the plastic chassis.
There’s a good reason this laptop has a plastic frame: it helps make it lightweight and durable. Lenovo also has this IdeaPad with a MIL-STD-810H certification. That is a huge plus, and it means it can withstand lots of drops and survive the beating a notebook for school or work might take.
Plastic also means the laptop is pretty lightweight for its class. Coming in at 3.51 pounds, it’s heavier than the 2.5-pound MacBook Air, but lighter than my 4.7-pound 16-inch MacBook Pro, which I frequently bring to work.
Lenovo says that the IdeaPad Slim 3i offers plenty of customization options in case material and color. There are five color options, as well as a polycarbonate or aluminum chassis. I would suggest the aluminum option if you can find it.
Outdated barreled charger
The port selection on this laptop is great, with three USB-A ports, a full-size SD card reader, USB-C, and a headphone jack. Unfortunately, to charge it when this laptop runs out of juice, you’ll likely need to use a barrel charger.
A USB-C port onboard the laptop allows for USB-C charging, but doing that means you lose access to the port. USB-C became standard for a reason: to avoid carrying around extra chargers. Nothing annoys me more than proprietary chargers like this one.
No back-lit keyboard
I often look back at my work late into the evening, and while typing part of this review in bed with the lights off, I found myself relying on the display’s backlight to find the right keys. It wasn’t impossible to type, but a backlit keyboard would have made the experience far more comfortable.
To Lenovo’s credit, the keyboard itself is pleasant to use. The keycaps have a lighter gray finish than the rest of the chassis and a slightly textured coating that makes them easy to distinguish by both sight and touch. That contrast helped me orient my hands in dim lighting, but it still isn’t a substitute for proper keyboard backlighting on a laptop at this price.
Lenovo IdeaPad Slim 3i 15 (2026): Verdict
The Lenovo IdeaPad Slim 3i 15 (2026) isn’t a bad laptop. It’s a dependable machine for $799. It checks three big boxes for what I look for: a bright screen, solid performance for productivity, and battery life to get me through a day’s work. For the students and office workers this laptop is designed for, there won’t be much to complain about.
The main issue is a few small compromises, such as the lack of a backlit keyboard and an outdated barrel charger. It isn’t Lenovo’s fault, though, as the ongoing RAM crisis likely led to cutting corners to keep the price down, which is why this laptop would normally be $1,299.
The MacBook Neo and XPS 13 are easily worth your money at around the same price. But if you ever see the Lenovo IdeaPad Slim 3i 15 for sale between $850 and $999, rather than at its full price of $1,300, it might be worth considering for its bigger screen.
