Lenovo IdeaPad Slim 3i 15 (2023) Laptop Review

The Lenovo IdeaPad 3i's design is simple and doesn't stand out in any way. It has a plastic chassis, relatively thin bezels around the display, a full-size keyboard with a numpad on the right, and ports on both sides. The speaker grills are at the top of the keyboard deck, and the air vents are on the bottom. This laptop is available in three colors: Abyss Blue, Artic Gray, and Frost Blue; however, availability varies depending on the region.

The Lenovo IdeaPad 3i's build quality is good. It's entirely plastic but feels sturdy; it just doesn't feel as premium as higher-end devices. There's some flex in the display and keyboard deck, but almost none on the lid when the laptop is closed. The finish doesn't pick up fingerprints or scratch easily, and the feet feel solid and stick firmly to the bottom.

The hinge is okay. It doesn't feel particularly smooth but is very stable, so there's almost no screen wobble when typing. Unfortunately, you can't open the laptop with one hand because the base of the laptop is too light and lifts with the lid.

Consider the HP Pavilion Aero 13 (2024) if you want a more compact mid-range option.

The Lenovo IdeaPad 3i's serviceability is decent. Accessing the internals is straightforward; you only need to remove 10 Philips screws and undo the clips holding the bottom panel. Unfortunately, the memory isn't user-replaceable, and there's only one storage drive slot.

The Lenovo IdeaPad 3i is available with the following displays:

• 15.6" TN 1920 x 1080 60Hz
• 15.6" IPS 1920 x 1080 60Hz
• 15.6" IPS 1920 x 1080 60Hz Touchscreen

A 1080p resolution looks decently sharp on a 15.6-inch screen. 16:9 is a standard aspect ratio that's well suited for media consumption since most videos are in the same format; however, a 16:10 or 3:2 aspect ratio would have been better for productivity, as the increased vertical space lets you see more text when reading a document or website, so you don't have to scroll as much. For the best viewing experience, it's best to get a model with an IPS panel because TN panels have worse viewing angles and color reproduction.

All available displays have a 60Hz refresh rate, which is typical for productivity laptops. The IPS (touchscreen) panel has a slow response time, causing noticeable ghosting, so it isn't ideal for viewing fast-moving content or gaming. The non-touch IPS and TN panels will perform similarly.

The contrast ratio is decent for an IPS panel but is still relatively low compared to other display technologies like VA and OLED. This contrast level makes blacks look gray in dim settings. The non-touch IPS panel will perform similarly, as it has the same advertised contrast; however, the TN panel will likely be worse, with an advertised contrast of 600:1.

The touchscreen IPS display gets reasonably bright. It's enough for use in most indoor settings but not outdoors in broad daylight. It gets very dim at the lowest brightness setting, which is great for dark room viewing as it causes less eye strain. The non-touch IPS panel will perform similarly. The TN panel is slightly dimmer, with an advertised brightness of 250 cd/m².

The reflection handling is excellent. The matte coating does a great job of diffusing and reducing the intensity of bright reflections. You can still see reflections when viewing light-color content with the screen at full brightness, but they aren't distracting.

The TN panel's uniformity will likely be much worse due to the TN panel's narrow viewing angles.

The horizontal viewing angle is okay. The image gets dimmer and more washed out fairly quickly when moving to the side, so you have to be close or directly in front of the screen to get the best accuracy. The TN panel will have a significantly worse viewing angle.

The vertical viewing angle is okay. Like the horizontal viewing angle, the image dims and washes out when viewing from above or below. You need to look at the screen almost straight on to get an accurate image, which can be hard in places where you don't have much space to tilt the screen, like on a bus or airplane. The TN panel's viewing angle will be worse as TN panels typically suffer from chroma inversion.

The Lenovo IdeaPad 3i's display accuracy is decent out of the box. The white balance is outstanding, but most colors are inaccurate due to the display's narrow color gamut. The color temperature is a tad cooler than the standard 6500K target, giving the image a slight, almost imperceptible, blueish tint. The gamma follows the sRGB curve reasonably well, although dark scenes look too dark, and bright scenes look too bright.

The display's color gamut is bad. It doesn't even have full coverage of the commonly used sRGB color space, making most content look washed out. Its Adobe RGB and DCI P3 coverage is also bad, so it isn't suitable for color-critical work like photo and video editing. The other displays perform similarly.

The Lenovo IdeaPad 3i has a good keyboard. The layout feels fairly spacious and is easy to get used to. The plastic used for the keycaps feels alright; it isn't particularly premium or cheap. As for the overall typing experience, the keyboard feels good to type on and doesn't cause fatigue over time. The keys have a lot of travel and don't require much force to actuate; however, they aren't the most stable keys, and the tactile feedback is just okay. Typing noise is relatively low and isn't bothersome in quiet settings. There's one backlight brightness level, so you can only turn it on or off. Backlighting is optional, so it's best to check the specifications if you need it.

The touchpad is decent. It tracks movements and gestures well; it's just small, making actions like dragging and dropping over a long distance more challenging. The surface feels smooth, allowing the fingers to glide easily, and there's no problem with palm rejection. Unfortunately, you can only click in the lower half of the touchpad, and the buttons feel a tad mushy.

The speakers are sub-par. Although they get very loud with minimal dynamic compression at max volume, they sound tinny, unnatural, and slightly sibilant. Also, they have no bass whatsoever.

The webcam is good. There's a fair amount of detail in the image, and the colors look natural; however, the exposure is slightly too high, and some smaller details look blurry due to noise. Voices sound loud and clear over the microphone with almost no background noise. Some models have a 1080p webcam, so it's best to check the specifications if you care about this. Keep in mind that a higher resolution doesn't always mean better image quality, as image processing tends to be more important when it comes to webcams.

The Lenovo IdeaPad 3i has a good port selection. Both USB-A ports support USB 3.2 Gen. 1 data transfer speed (up to 5Gbps). The USB-C also supports USB 3.2 Gen. 1 data transfer speed, DisplayPort 1.2 (video output up to 4k at 60Hz), and Power Delivery 3.0. The latter allows for fast charging of the laptop and other PD-compatible mobile devices connected to the port.

The Lenovo IdeaPad 3i's wireless adapter is a Realtek RTL8852BE.

The Lenovo IdeaPad 3i is available with the following CPUs:

• Intel Processor U300 (5 cores (1P + 4E)/6 threads, up to 4.4GHz, 8MB cache)
• Intel Core i3-1305U (5 cores (1P + 4E)/6 threads, up to 4.5Ghz, 10MB cache)
• Intel Core i3-1315U (6 cores (2P + 4E)/8 threads, up to 4.5GHz, 10MB cache)
• Intel Core i5-1335U (10 cores (2P + 8E)/12 threads, up to 4.6GHz, 12MB cache)
• Intel Core i7-1355U (10 cores (2P + 8E)/12 threads, up to 5.0GHz, 12MB cache)

All available CPUs are designed for general productivity tasks like web browsing, text processing, spreadsheets, and video playback. They all have a hybrid design with a mix of performance and efficiency cores. The Intel Processor U300 and Core i3-1305U have one performance core and four efficiency cores. The Core i3-1315U, i5-1335U, and i7-1355U have two performance cores, but the number of efficiency cores varies, from four on the Core i3 to eight on the Core i5 and i7. As usual, a higher core count and faster clock speeds will result in a smoother desktop experience with less slowdown when multitasking. The Core i5 and i7 can handle more demanding applications; however, if you're using your laptop for heavy workloads like 3D graphics or video editing, you're better off getting a laptop with an H-series processor, as those CPUs have more performance cores and run at a higher wattage.

The Lenovo IdeaPad 3i is only available with integrated graphics. The Processor U300 and Core i3s use Intel UHD Graphics (48 and 64 execution units, respectively), while the Core i5 and i7 use Intel Iris Xe (80 and 96 execution units, respectively). There's a performance difference between the various GPUs, but ultimately, they're all designed for light productivity tasks, not demanding workloads like video editing or 3D graphics. The Core i5 and i7's Intel Iris Xe can handle some lighter or older games, although you'll have to play with low graphical settings to get playable frame rates.

You can configure this laptop with 8GB or 16GB of RAM. The memory is soldered onto the motherboard and isn't user-replaceable, so get the best configuration for your needs upfront.

You can configure this laptop with 256GB, 512GB, or 1TB of storage. The SSD is user-replaceable; the slot supports an M.2 2242 PCIe Gen. 4 x4 NVMe SSD.

The Lenovo IdeaPad 3i has an overall good score in the Geekbench 5 benchmarks. These scores indicate that the Core i3-1315U can easily handle light productivity tasks but will struggle in extremely demanding multi-threaded workloads. The Core i5-1335U and i7-1355U are faster because they have more cores. That said, If you need to run intensive, heavily multi-threaded applications, it's best to get a laptop with an H-series processor. As for the GPU's performance, the Intel CPU's integrated graphics perform poorly and aren't suitable for heavy computing tasks.

The overall score in Cinebench R23 is excellent. However, if you're a professional with strict deadlines, you can get far better performance on a mobile workstation or gaming laptop with an H-series CPU. Upgrading to the Core i5 or i7 on this laptop will also give you better performance, but it won't be as good as an H-series processor.

The Lenovo IdeaPad 3i's performance in Blender is sub-par. The Core i3-1315U takes a long time to render the simple bmw27 scene. The Core i5 and i7 will perform significantly better, but it's still better to get a laptop with a dedicated GPU if you need to render images professionally. Even an entry-level GPU, like an NVIDIA GeForce GTX 1650, can render images much faster than almost any CPU.

The Lenovo IdeaPad 3i performs poorly in the Basemark GPU benchmark. The Intel U300 and Core i3s' UHD graphics can only handle simple card and puzzle games. The Core i5 and i7's Intel Iris Xe GPU isn't bad for integrated graphics; however, it's starting to show its age and isn't fast enough to provide smooth gameplay in graphically intensive titles. You can play some older or extremely well-optimized titles at 1080p, but you'll have to play at a lower resolution or with low graphical settings to get playable frame rates.

Borderlands 3 isn't playable on the Lenovo IdeaPad 3i laptop. The average frame rate is too low, even with low graphical settings, and the game sometimes freezes completely. Also, the game can only run on DirectX 11 because it keeps crashing on DirectX 12. The Core i5 and i7's Iris Xe will perform better, but not enough to make it playable. You can expect the same performance in other similarly demanding titles.

Civilization VI runs poorly at 1080p with high settings because the average frame rate is too low, even for a strategy game. However, it runs much more smoothly if you lower some graphical settings. The Core i5 and i7's Iris Xe graphics will provide smoother gameplay and faster turn times.

CS:GO runs poorly at 1080p. Although the average frame rate is over 60 fps with low graphical settings, the game stutters a lot due to frame drops. The Core i5 and i7 will push slightly more frames per second, but the game will still stutter.

Shadow of the Tomb Raider isn't playable at 1080p. The game is too choppy and sometimes freezes completely, even with low graphical settings. The integrated GPU simply can't handle this and other similarly demanding games. The Core i5 and i7 will perform better, but not enough to make the game playable.

The Lenovo IdeaPad 3i has good thermal and noise handling. The keyboard is only mildly warm when idle, and the fan is completely silent. Under load, the keyboard gets hotter but is by no means uncomfortable. Likewise, the fan is audible at full speed but isn't annoying or distracting.

The Lenovo IdeaPad 3i has many pre-installed applications, including:

• Dolby Access: Adds Dolby Atmos support and lets you tweak the speakers or headphones settings. Includes a seven-day trial; additional one-time purchase required for use after the trial period.
• Lenovo Hotkeys: Lets you create keyboard macros.
• Lenovo Smart Appearance: Improves your appearance on video calls.
• Lenovo Vantage: Checks for drivers and BIOS updates. It also lets you view the system's status and warranty information and access various settings, like power and audio profiles.
• Lenovo Voice: Text-to-speech application.
• Lenovo Welcome: Provides general information about the laptop for new users.
• McAfee LiveSafe: Antivirus and internet security software. Requires subscription.
• TikTok: Social media app.

You can get this laptop with Windows 11 Home pre-installed or without an operating system. Some models ship with Windows in S Mode, a stripped-down version of Windows designed for low-end hardware. It only lets you install apps from the Windows Store, which means you can't install apps like Google Chrome or Mozilla Firefox. You can switch out of S mode free of charge, but you can't go back to it once you've activated the full version of Windows.

The power button has an integrated fingerprint sensor. You can use it to log into Windows, authorize Windows Store purchases, and auto-fill saved passwords on supported websites. The fingerprint sensor is an optional feature, so it's best to check the specifications if this is a feature you care about.
