Asus Vivobook S15 hands-on review: The brand’s first ARM PC offers excellent battery life

The Asus Vivobook S15 is its first laptop powered by the ARM Snapdragon X Elite chip. This 15-inch OLED screen boasts record-breaking performance.Asus Vivobook S15 Laptop Battery

It boasts exceptional battery life, but ushering in the era of ARM PCs is a tall order for the Taiwanese manufacturer. Conclusion

Asus’s first laptop powered by a Qualcomm ARM chip showcases the architecture’s potential under Windows. While its raw performance, especially in graphics, isn’t up to x86 standards, the Asus Vivobook S15’s battery is worth keeping.

Its battery life is impressive. With a well-built chassis, a stunning OLED display, and comprehensive connectivity, the Vivobook S15 is feature-rich. However, its software still needs time to mature. However, if you need a new computer but don’t plan on using it for gaming, the Asus Vivobook S15 laptop battery…

If battery life is your priority, the Vivobook S15 is already a very good choice, and its performance will continue to improve over time. In fact, battery life is undoubtedly a strong point of the Vivobook S15. The Snapdragon X Elite X1E-78-100 platform, with its 70 Wh Asus Vivobook S15 Laptop Battery

 and Qualcomm’s power management technology, delivers impressive endurance.

It even outperforms the M4-powered MacBook Pro 14 (which we tested a few days ago). This computer outperforms other PC competitors, as we were able to work away from a power outlet for two days without needing to recharge. We’re talking two days a week, nine to ten hours a day. So, with typical office use, theAsus Vivobook S15 Laptop Battery

It should last 18 to 19 hours! The VivoBook S15 also comes with a 90W USB-C charger, which can charge the phone to 50% in just 45 minutes. A full charge takes about two hours.

The HP Envy x360 is one of the best 2-in-1s we’ve used this year.

The HP Envy x360 is a 2-in-1 laptop that supports Microsoft Pen protocol and touch gestures and is available in a variety of configurations. You can choose between two sizes: 14-inch or 16-inch; our review unit is the 16-inch model. For processors, you can choose from the AMD Ryzen 5 8640HS, Ryzen 7 8840HS, Intel Core Ultra 7 155U, Intel Core Ultra 5 125U, Intel Core 7 140U, or Intel Core 5 120U.
RAM is available in 8GB or 16GB configurations. For storage, SSD options include 256GB, 512GB, 1TB, or 2TB. You can also choose between a 1920 x 1200 IPS display or a 2880 x 1800 OLED display.HP Envy x360 16-inch Laptop Battery
: 68Wh lithium-polymer battery. Short battery life isn’t uncommon for large laptops, but even this is disappointing. The HP Envy x360 lasted a total of 6 hours and 18 minutes before finally running out of power. This is an improvement over the older HP Envy x360, but it’s not a significant improvement. When testing the laptop, we set the display brightness to 200 nits and switched the battery settings to power saving mode. We then simulated a moderately productive workday on a fully charged laptop, cycling through approximately 20 Google Chrome tabs until the HP Envy x360 16-inch Laptop Batterydepleted.Other 16-inch laptops, notably the HP Pavilion Plus 16 and the 2024 Dell XPS 16, offer eight hours or more of battery life without compromising performance or thinness. Yes, this is a premium laptop at an affordable price.
You have to accept that.Envy x360 BatteryThe battery life is just over six hours. Among 2-in-1s, the HP Pavilion Plus 16, Lenovo IdeaPad Flex 5i, and Lenovo Yoga 9i Gen 8 all outperform it; if you’re willing to consider a traditional laptop, the Acer Swift X 14 and LG Gram 17 also offer excellent battery life.
While the Envy x360 isn’t a perfect laptop, it’s well-made, reliable, fast, and offers an amazing user experience. At this price point, you’d be hard-pressed to find a more powerful 2-in-1 laptop that’s also more affordable.

Gamers will definitely want to use headphones with this machine. The speakers are all about clarity. HP Envy x360 14 Laptop BatteryBattery life has indeed improved significantly.
This company is constantly innovating, pushing the boundaries in design, features, and an overall excellent display.

Acctual Battery Performance (HP Envy x360 14 Laptop Battery Life)
The Envy x360 14 is positioned as a high-end portable 2-in-1 laptop, so battery life is a key selling point. Actual battery life will vary greatly depending on configuration (especially the processor) and usage scenarios. Overall, its battery life is excellent and among the best in its class.

At 50% screen brightness, with power saving mode enabled, and primarily engaged in document processing, video conferencing, and web browsing, the HP Envy x360 14 laptop battery
typically lasted 7-10 hours or more.
Best of all, you have access to HP’s extensive service center network. This is one of the best 2-in-1 convertibles I’ve used in a long time.

MSI Katana 17 HX laptop review: RTX 5070 gamers still have room for improvement

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…

Battery life. There’s little to complain about the screen: aside from a slightly lackluster brightness, the 240Hz display performs well in almost every way.

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.”

This is a budget-friendly gaming laptop equipped with an Intel Core i7 and an Nvidia GeForce RTX 4050, with good overall build quality.

While the 75W battery life sounds impressive, it’s a different story if you dare to crank up the brightness and try to game for extended periods unplugged. I averaged about three and a half hours playing less GPU-intensive games like Deadly Company, but with more demanding titles, I could only average two hours.
Even when I put the device in power saving mode and performed only typical productivity tasks, the battery dropped to 50% in just two hours. By enabling Windows 11’s power saving mode, I managed to extend the Acer Nitro V 15 Laptop Battery life of my Acer Nitro V 15 laptop until I had to remove the power adapter.

Asus ZenBook Flip S UX371 review: Tiger Lake processor, OLED screen

ZenBook Flip S UX371 Industrial Design and DisplayThe ASUS ZenBook Flip S is made of aluminum alloy with exquisite copper decorations on the edge of the top cover and around the body. For those who like black laptops, but not too bright or eye-catching, this laptop will definitely be popular.Regarding the battery information of ZenBook Flip S UX371, here are the key points:ASUS ZenBook Flip S UX371 Laptop Battery
CapacityThis model is usually equipped with a 4-cell lithium polymer battery with a capacity of 67Wh (specifics may vary slightly depending on configuration or region). Supports fast charging technology, which can be charged to 60% in about 49 minutes (original adapter required).

ASUS ZenBook Flip S UX371 Laptop BatteryLifeThe official nominal battery life is about 15 hours (actual use is about 8-12 hours, depending on screen brightness, performance mode and usage scenario). Flip touch screen and 4K resolution (some configurations) may increase power consumption.
The display has a maximum brightness of 500 nits. The display has 100% DCI-P3 color gamut coverage, and the same wide 178-degree viewing angle as most IPS displays. Between 500 nits for bright white and 0 nits for dark white. ZenBook Flip S UX371 Thermal Solution, Keyboard, and Audio System
Above the display is a 720p webcam with an infrared sensor that works with Windows Hello’s facial recognition system. The infrared sensor works very quickly, but sometimes it can’t recognize us even when we are in its line of sight.Asus ZenBook Flip S UX371 Laptop Battery ReplacementThe battery is built-in and cannot be replaced by yourself. If you need repairs, it is recommended to contact Asus official after-sales or authorized service centers. When the battery life decreases (such as significantly reduced battery life), you can use the Asus diagnostic tool to detect health.


The 720p camera sensor also performed well in Skype calls. A good lighting setup is always essential for video calls, and the ZenBook Flip S’s camera is as clear and light-sensitive as any other webcam we’ve looked at recently. Two microphones are located on either side of the camera to cancel out room audio, and callers had no problem hearing us.
PrecautionsAvoid prolonged use in high-temperature environments to extend the life of the Asus ZenBook Flip S UX371 laptop battery replacement.>>>>>>>>>>>>>>>>>>>>C21N1706 5070mAh Battery Replacement for Asus ZenBook Flip S UX370 UX370U UX370UA

In terms of appearance, the camera area of the two products in the ThinkPad X9 series protrudes upward, while the main body is as thin as possible, and only the I/O interface parts at the rear and front are in contact with the desktop, making the X9 series visually closer to Lenovo’s other notebook series.
The 14-inch model is expected to be equipped with a 1920×1080 resolution non-touch matte display and a 55Wh Lenovo ThinkPad X9 BatteryIn terms of configuration, the ThinkPad X9 series is expected to be equipped with Intel Core Ultra 200V series processors, with at least optional Ultra 5 226V (16GB memory) and Ultra 7 258V (32GB memory), equipped with 512GB or 1TB solid-state drives, and support Wi-Fi 7 and Bluetooth 5.4.The 15-inch model will be equipped with a 2880×1800 resolution non-touch matte display and 80W Lenovo ThinkPad X9 BatteryThe latest exposure of the ThinkPad X9 series 14-inch and 15-inch models uses a new material in design, abandoning the iconic red dot of the ThinkPad series.

It is equipped with Intel’s new Core Ultra chips (Core Ultra 7258V and Core Ultra 9 288V processors) based on the Lunar Lake platform and integrated Arc Xe2 graphics.Lenovo ThinkPad X9 BatteryMaintenance advice: Avoid long-term full-charge storage (charge thresholds can be set through Lenovo Vantage software). Use the battery regularly (avoid long-term plug-in without battery).
It has many features required for top-level business devices, as its 2.8K OLE display with HDR, 120Hz refresh rate and 1ms response time should attract professionals who need clarity and speed. Lenovo ThinkPad X9 Moonlight White with a new aesthetic design Its on-device AI acceleration of up to 48 TOPS is another nod to the engineering and creative crowd, making it a strong contender for the best laptop for the needs of engineering students.
However, as the drastic reduction comes at a cost, practicality is also compromised. With only two Thunderbolt 4 ports, an HDMI 2.1 port, and a 3.5mm headphone jack, users who rely on multiple external devices such as USB-A devices, SD cards, and Ethernet may find connectivity poor.

MSI Raider 18 HX AI review: A benchmark-breaking beast of a laptop

The MSI Raider 18 HX AI is a typical “desktop replacement” laptop. It’s bulky, looks unremarkable, and has a mediocre trackpad, which means users actually need to connect a mouse.MSI Raider 18 HX AI: Specs and FeaturesThe highlight of the MSI Raider 18 HX AI spec sheet is undoubtedly the Nvidia RTX 5080. This new mobile GPU is destined to become the new go-to for mobile gamers, with an impressive 175 watts of graphics processing power.


But there’s more to the story than that. The Raider 18 is also powered by Intel’s new Core Ultra 9 285HX processor, which has 24 CPU cores. The model I reviewed came with 64GB of RAM and a 4TB PCIe 5.0 SSD. It also has a Mini-LED display.MSI Raider 18 HX AI Laptop Battery
Capacity: 99 WhThe MSI Raider 18 HX AI isn’t the company’s largest, most powerful laptop—that’s the MSI Titan—but it’s still solid. It weighs about 8 pounds and is about 1.25 inches thick. That’s not unusual for a gaming laptop as large and powerful as the Raider 18, but it’s worth noting. You’ll notice it when you carry this laptop in your bag, and it won’t even fit into many mid-sized backpacks.MSI Raider 18 HX AI: Webcam, Mic, BiometricsMSI equipped the Raider 18 with a 1080p webcam. It delivers good video quality in a well-lit to moderately bright room.

The Raider 18’s own camera output isn’t great, as 1080p is well below the display’s 3,840 x 2,400 resolution. The camera’s image quality was decent on a Zoom call, though. The camera also features a physical privacy shutter. Well, that usually takes a long time.MSI Raider 18 HX AI Laptop BatteryIt took just over six minutes to complete the test, which is an incredible result. The Intel Core i9-14900HX system, the fastest we’ve tested to date, took more than eight minutes to complete the same task. MSI Raider 18 HX AI: Battery LifeThe MSI Raider 18 HX AI attempts to deliver acceptableMSI Raider 18 HX AI Laptop Batterylife with a massive 99 watt-hour laptop battery, which is the largest capacity you’ll find in a modern laptop (due to FAA restrictions on battery size in carry-on items).


However, the laptop comes standard with a 400-watt power adapter, while MSI claims it’s rated for a total of 260 watts. While you won’t use that much power when powered byMSI Raider 18 HX AI Laptop Battery you can still see the problem. 260 watts is a lot more than 99 watts.
It’s not a demanding test, but it still keeps the Raider 18’s battery life in the low single digits, behind most similar laptops.
MSI Raider 18 HX AI: VerdictThe MSI Raider 18 HX AI is a model of hardware. It has an Intel Core Ultra 9 285HX processor that sets new records in multiple benchmarks; an Nvidia RTX 5080 GPU that’s close to the performance of the RTX 4090; and a pair of PCIe 5.0 SSDs with read speeds of up to 13,000 MB/s. It also has a bright Mini-LED display. The Raider 18 HX is designed to deliver top performance in every task possible, while its competitors, such as the Gigabyte Aorus Master 18 and Asus ROG Strix 18, are more focused on gaming performance.

M4 MacBook Air vs. M3 MacBook Air: Here are the biggest upgrades

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.
