I then took some synthetic benchmarks at the three different settings in Lenovo Vantage, all with the MUX set on dGPU. First was in Performance mode: I also did some testing with a number of games. All these tests were done in performance mode in QHD and FHD at 16:10: Once opened, you get a good look at the screen, which is surrounded by a plastic bezel. The left and right bezels are pretty small, which is the standard nowadays. The top bezel is a little larger and the bottom bezel is twice the size. There’s a Legion logo centered on the bottom bezel and a standard webcam centered at the top.

I’ve read other reports of middling battery life. I’m not sure how to respond to that though, because I think these results are pretty decent considering the hardware involved. Gaming laptops in general usually have awful battery life, so this is refreshing to see. Perhaps they also didn’t know you could turn the iGPU on – it makes a huge difference. The fans are also exactly the same. They are pretty large in size and identical to the other Legion laptops. The only disappointment I have is the right fan on the GPU side could have been larger, but Lenovo chose not to. Could be for sourcing concerns for consistency, but I hate to see such a large empty space in a laptop. Seems like a wasted opportunity. And here’s how this 2021 Legion 5 fares in the Cinebench R15 loop test on the Performance, Balanced and Quiet profiles. As for external temperatures, there were no surprises with this laptop. I took some FLIR readings so you can get a look at what to expect with normal tasks on battery and again with a heavy gaming session. As for the SSD, my unit comes with a 1TB drive which is made by Hynix. These drives are fine and have decent speeds as far as NVMe drives go. It’s an AMD laptop so you’re limited to PCIe gen 3.0, which is what this drive is. There’s also a spare slot if you wanted to upgrade, but note that SATA drives are no longer supported in most Legion laptops.I took a bunch of battery measurements, with Optimus on and with the screen set at 60% brightness, roughly 90 nits. Here were my results: In the BIOS, I was able to OC the GPU with some predefined settings. Here are the new results from adding +100Mhz: USB-A 3.2 gen2, 1x USB-C 3.2 DP 1.4, 1x USB-C with DP 1.4 and PD support, 1x HDMI 2.1, ethernet, mic/earphone

Next is Maxon's CPU-crunching Cinebench R15 test, which is fully threaded to make use of all available processor cores and threads. Cinebench stresses the CPU rather than the GPU to render a complex image. The result is a proprietary score indicating a PC's suitability for processor-intensive workloads. The good news is, I didn’t have any problems with this one like I did with the 15” Legion 5. So far, it has been working just fine. My speed test results in 430Mbps at about 30 feet away from my router. This module also has Bluetooth 5.2 which seems to work fine for me. USB-A 3.1 gen 1, 1x USB-C 3.2 gen2 with Data, gen1, power and DP, 1x USB-C 3.2 gen1, HDMI 2.1, LAN, headphone/mic The keyboard on the 17” version is almost identical to the keyboard on the 15” Legion 5. I had zero trouble typing on it, as I’ve adapted pretty well to typing on Legion keyboards for the past several months.The other thing to note is just how much better Quiet mode is on the CPU temps and the noise level. It’s so much quieter that would probably play games in this mode much of the time, if I used this laptop daily. For some games, including Horizon Zero Dawn, shifting to Quiet mode doesn’t cripple performance, but there is a noticeable impact on other titles, so you’ll have to test out the profiles yourself. This Legion 5 has an 80Whr battery, which is a pretty decent size. I’m sure it’s to be consistent with the other Legion models, but it would have been nicer to utilize that extra space and beef it up to 99Whr. The Ryzen 7 6800H and 150 W GeForce RTX 3070 Ti are each about 10 percent faster than the Ryzen 7 5800H and 140 W GeForce RTX 3070 on last year's Legion 5 Pro. The 2022 refresh is therefore merely just a minor upgrade over the 2021 model with no major external or internal changes.

It’s interesting seeing the brightness settings on this model, mainly because of how drastic they fall off between 80-100%. I found myself using 60% for typical use in low lit rooms, where on most other laptops it would be 30%. While gaming I almost exclusively kept it at 90%, mainly because 100% was too bright. But having that extra 150+ nits was prefect for those times I was typing next to my bright dining room window. We also run a custom Adobe Photoshop image-editing benchmark. Using an early 2018 release of the Creative Cloud version of Photoshop, we apply a series of 10 complex filters and effects to a standard JPEG test image, timing each operation and adding up the total. As with Handbrake, lower times are better here. The Photoshop test stresses the CPU, storage subsystem, and RAM, but it can also take advantage of most GPUs to speed up the process of applying filters, so systems with powerful graphics chips or cards may see a boost.The mids and highs sound just ok, but the bass is limited to as low as 100Hz. Even so, the sound is decent for movie streaming or watching Youtube. Just don’t expect your favorite song to sound like it does on some quality headphones or speakers.

By the way, if that light doesn’t bother you while the laptop is in use, perhaps it will find other ways to bother you. If you’re like me and shut your lid to enter sleep mode, prepare to watch hours of pulsating logo while it sits there on your desk. So dumb – Fn-L On paper, it’s a lot of what I’ve been looking for. Good screen, powerful GPU, stylish and yet not gamer-looking design, and some upgrade options. My main concerns were with the overall size of it and the weight. I am coming from a Razer Blade 15 after all, so good build quality was definitely on my list of desires. W (~5 h 56 min of use)– 1080p Youtube fullscreen in Chrome, Better Battery Mode, screen at 70%, Wi-Fi ON, screen set to 144Hz; W (~1 h 20 min of use)– Gaming – Witcher 3, Maximum Performance Mode, 60fps, screen at 70%, Wi-Fi ON.The Legion 5 Pro has an 80Whr battery, which is a pretty decent size. Judging from the inside, it doesn’t look like they had any more room for something bigger either. The bottom panel isn’t too fancy, but I actually prefer it this way. There are some very good footpads on this unit too. They are very grippy, both by the hand and on the surfaces. There’s ample ventilation for the intakes too. The entire cover is held in place by clips and phillips screws. Arguably, the main draw to this laptop is the unique 16” screen. It’s an unusual size, and it’s because it comes with an uncommon 16:10 aspect ratio. The resolution is 2560×1600, offering more than 10% extra vertical space than a traditional 16:9 screen. This article down below gathers our early thoughts on these updated Legion 5 lineups, and is a work in progress as we’re filling up the blanks. If I were to use this regularly, I would probably choose a TDP of 25C. This seemed to have minimal impact of most games, and yet limited the fan noise closer to 50dB, while in Performance mode. It also allowed the TGP to hover close to 140W for longer periods of time, offering better GPU performance. I didn’t spend a lot of time using this tool, but it’s nice to know it works.
