Lenovo IdeaPad Slim 3 15IRU9: Two-minute review

You’re not going to be wowed by the Lenovo IdeaPad Slim 3. But, if you’re looking for a laptop that’s “good enough,” a phrase you’ll see me use throughout this review, then you might be a fan of this laptop, especially considering that you can get it for fairly cheap.

In fact, its portability, decent enough performance, and pleasant aesthetics, particularly the Abyss Blue colorway, make it a contender for the best budget laptops out there right now. Considering that this is a slightly older model, you most likely will find it at a discount.

Being a more budget-oriented product does mean that it comes with a whole heap of compromises, from a mostly plastic built to shorter battery life and subpar audio quality. But, if you’re looking for one of the best laptops overall, you’ll probably need to spend a little more to get it.

The Lenovo IdeaPad Slim 3 is purely for those people who just need a laptop and want something that’s new, portable, and comes with Windows.

Lenovo IdeaPad Slim 3 15IRU9: Price and availability

• How much does it cost? Starting at $539.99 / £510 / AU$1,149.00
• When is it available? Available now
• Where can you get it? Available in the US, UK, and Australia

The 15-inch version of the Lenovo IdeaPad Slim 3 is available in the US, UK, and Australia, but, like most things Lenovo, is available in slightly different configurations per territory. For instance, the cheapest version of this laptop, which goes for $539.99 / £510 / AU$1,149.00, is available in the US, whereas the more powerful versions are available in the other territories.

While the highest configuration’s price tag is a bit exorbitant, especially since it’s mostly for more storage, the cheapest configurations make it a good idea for those looking to just get a laptop that’s thin, light, and doesn’t look cheap.

There are other options out there, such as the Acer Aspire 5, that offers a little more in terms of performance and battery life, but is a bit more limited when it comes to ports. It’s also almost half a pound heavier than the IdeaPad Slim 3.

Lenovo IdeaPad Slim 3 15IRU9: Specs

The Lenovo IdeaPad Slim 3 15IRU9 may be a more budget-oriented model but it still comes with some customizations. For starters, you can choose between three CPUs: the Intel Core 3 100U, Intel Core 5 120U, and the Intel Core 7 150U. The more powerful the processor the snappier the response will be for browsing and day-to-day tasks. There’s also a choice between 8 and 16GB of RAM, though you can only get 8GB with the Intel Core 3 and 16GB with the Intel Core 7 CPU. Lastly, you can choose an SSD ranging from 256GB (there is the ability to just do a 128GB flash drive in the UK) to 1TB of space.

There is some light customization available outside of the internal components as well. You can upgrade from a non-touch to a touch screen. And you can choose whether to pay extra for a fingerprint reader. There’s also a color choice between Abyss Blue (reviewed here) and gray.

Lenovo IdeaPad Slim 3 15IRU9: Design

• Is thin, light, and looks nice, though it’s not the most premium build
• Keyboard and touchpad are fine
• Has some appreciated security features like a webcam privacy shutter

Available in either Abyss Blue or gray, the Lenovo IdeaPad Slim 3 offers up that distinctive Ultrabook aesthetic. It’s thin, light, and, from afar, looks like a MacBook competitor. Of course, upon closer look, its mid-range bones are more apparent, like the fact that its chassis is made out of plastic.

However, it’s a nice option for people who just need a computer and don’t care about getting something expensive or top-of-the-line. It comes with a decently-sized 15.6-inch display that, at 1080p, is good enough for most people. Plus, that display on upgraded models such as the one reviewed is a responsive touchscreen.

The keyboard falls into the “good enough” camp, as it does the job but isn't particularly special. The keys are a bit stiff to the touch, so may not be a favorite of those typing out long essays. And there’s no backlighting either. At least there’s a numpad. The touchpad is equally fine; it’s accurate and responsive, but isn’t the smoothest to the touch.

Port-wise, you do get a nice assortment such as there’s an HDMI and SD card reader port, both of which you don’t always get in this caliber of computer. Of course, there’s the typical USB-C and USB-A ports as well as a headphone jack.

Lastly, there are some security features on hand that I do appreciate. Namely, there’s a fingerprint reader on the power button and privacy shutter on the webcam.

Lenovo IdeaPad Slim 3 15IRU9: Performance

• Good enough performance for day-to-day work
• Webcam is sufficient but limited
• Audio is underwhelming

When it comes to performance, the bar is somewhat low for the Lenovo IdeaPad Slim 3 in that it doesn’t need to power demanding programs like games or editing software (if you’re looking for that kind of power, there are plenty of other laptops to consider as this is not one). What it needs to do and does well enough is handle day-to-day tasks such as browsing, streaming, emails, word processing, and the like. And it does those just fine. This laptop is meant for people who “just need a computer” at an affordable price.

During use, I was able to use it normally with 15 tabs open in a browser, including some streaming, without much of a slowdown other than a split second refresh when switching tabs. The cheapest configuration, with its 6-core Intel Core 3 100U CPU and 8GB of RAM, will probably start to slow after just a couple years as it already has somewhat weak internals. The review configuration, however, has a 10-core CPU and 16GB of RAM, so should offer an additional year of use, in my opinion, before starting to feel slow.

Since this fits into that category of devices that look like an Ultrabook, but are more of a budget laptop, there are some compromises elsewhere. The webcam, for instance, is good enough but at 720p @ 30 fps, is not the sharpest or smoothest. Plus, it does have a little grain to the image in low light settings.

More egregiously, the audio is underwhelming. While this is somewhat typical for budget and mid-range laptops, it’s worth pointing out. There’s not much in the way of bass or high-end, leaving you with a boxy, mid-range quality, like hearing something through a phone. Considering how many people simply stream stuff onto their laptops these days, it’s surprising that this isn’t better.

Lastly, it should be mentioned that, like most budget laptops, this comes with some bloatware.

• Performance: 4 / 5

Lenovo IdeaPad Slim 3 15IRU9: Battery life

• Decent but not great battery life
• Has fast charging on hand

With a benchmark of six hours and almost 15 minutes, the Lenovo IdeaPad Slim 3 is not going to win any awards. That length of time is good enough if you need to do a little work on the road, but not enough to get through a full work day without a charge. And it’s pretty low compared to what a lot of thin and light laptops, particularly Ultrabooks (that happen to be a little pricier on the whole), are able to achieve. The only laptops that this really beats out are gaming laptops that have to also supply power to dedicated graphics cards and older models that you probably wouldn’t compare this to in the first place.

On the bright side, there is fast charging on hand so that you can quickly get some extra juice with a short trip to an outlet. I was able to charge back up from 55% after about 40 minutes. So, if you want to go untethered to work while in front of the TV, you have enough battery life on hand and get a quick charge for more while taking a quick break.

How I tested the Lenovo IdeaPad Slim 3 15IRU9

• Tested for a couple weeks
• Used it for work, gaming, and streaming
• Tested its webcam and audio

I used the Lenovo IdeaPad Slim 3 15IRU9 for a couple weeks, doing some light gaming, watching some online content, and working on it. I also used it on the go and tested its various features like the webcam and audio.

The Lenovo IdeaPad Slim 3 15IRU9 is one of those laptops meant for people who don’t need crazy powerful computers, but instead just need a decent sized screen, good portability, and enough power for normal day-to-day work without costing too much money.

I’ve spent the last few years reviewing tech gear for gaming and otherwise, where I’ve gotten a feel for what to look for and how to put a piece of kit through its paces to see whether it’s worth the recommendation.
