Can this 17-inch laptop remain competitive? The Katana 17 HX B14WGK faces challenges not only within the MSI lineup but also compared to its peers. While the build quality is excellent, it’s prone to creaking and feels less premium overall. The ports also reflect MSI’s cost-cutting efforts. There are no Thunderbolt or modern USB ports (keyword: USB 4), nor is there a card reader.

The MSI Katana 17 HX is a powerful gaming laptop.

MSI Katana 17 HX Battery Specifications: MSI Katana 17 HX Laptop Battery Type: 4-cell Lithium-ion (Li-polymer) Battery

Capacity: Typically 53.5 watt-hours (varies by model). Expected Battery Life: Gaming: Approximately 1.5-2.5 hours (depending on GPU/CPU load). General Use (Office/Web): Approximately 3-5 hours. Power Adapter: Typically 240W-280W (required for optimal performance).

Furthermore, the noise level is so high under high load that it almost forces the user to use headphones. MSI could also improve the keyboard (which takes some getting used to), speaker quality, webcam quality, and…

MSI Katana 17 HX Laptop Battery life

Don’t expect too much from battery life. In our Wi-Fi test (with brightness reduced to 150 cd/m²), the MSI Katana 17 HX laptop’s 75 Wh MSI Katana 17 HX Laptop Batteryonly lasted about 5 hours. Competitors, by comparison, offer battery life of 7 to 9 hours.

The GeForce RTX 5070’s mixed reviews stem largely from Nvidia’s product strategy. Furthermore, 8GB of video memory is no longer enough in 2025, especially for resource-intensive apps like Raiders of the Lost Ark, though GDDR7 could at least alleviate this somewhat. Beyond that, the 17-inch screen is pretty mediocre—that is, it doesn’t have any particularly outstanding strengths or weaknesses, ultimately qualifying it as “good.”

Just one day after announcing the all-new iPad Air, Apple has released an update to its accompanying Air-branded laptop. The M4 MacBook Air features the latest Apple Silicon powertrain and some other welcome additions.MacBook Air M4 Laptop Battery 18 hours (Apple claims)MacBook Air M3 Laptop Battery15 hours 13 minutes (13-inch, tested); 15 hours 2 minutes (15-inch, tested)
M4 MacBook Air vs. M3 MacBook Air: Design and DisplayBoth the 13-inch and 15-inch M4 models look identical to their M3-based predecessors, but that’s not really a problem, as the MacBook Air is still one of the most beautiful laptops around. The main difference between the two laptops is the chipset that powers them. The latest Air is powered by Apple’s M4 chipset, which debuted last spring with the 2024 iPad Pro, while the M3 models are powered by a slightly older (but still pretty impressive) processor.
Apple says the 10-core CPU (two more cores than the 8-core M3) is twice as fast as the M1 MacBook Air, but the difference between the M4 and M3 won’t be that big. There are smaller upgrades to the camera. The M3 MacBook Air had a 1080p camera, while the new model has a 12-megapixel sensor and adds Center Stage technology.
M4 MacBook Air Battery vs. M3 MacBook Air Battery Life
Apple didn’t reveal the MacBook Air M4 Laptop Battery  capacity of the MacBook Air M4 laptop, so we’ll have to wait for the first M4 MacBook Air teardowns to know the exact number, but the company says both sizes will last up to 18 hours on a single charge.
That’s the same as Apple promised for the M3 models, so don’t expect much to change on that front despite the improved efficiency of the M4 chipset.
M4 MacBook Air vs. M3 MacBook Air: ComparisonThe M4 MacBook Air looks to be another premium laptop from Apple, with a host of substantial improvements. The speed of the M4 chipset, the addition of the Center Stage, and the ability to use three screens simultaneously are all extremely welcome — though not as welcome as the $100 price cut.
While it may not be worth it for users upgrading from last year’s model, owners of the M2 MacBook Air or earlier will be very tempted.
