Asus ROG Zephyrus G15

Asus ROG Zephyrus G15 is one of the most famous gaming laptop in BD. It is now available in our shop. Get Asus ROG Zephyrus G15 Price in BD and other info here . Buy this laptop from our shop with best Asus ROG Zephyrus G15 Price in BD .


Design and build quality:

The Zephyrus G15 is pleasing to the eye, especially the white version of the laptop I used to review. Asus has been churning out some very beautiful laptops lately, and for me, this is at the top of the list of beautiful laptops. Its profile is very thin, only 19.9 mm. It’s not exactly a slim and light laptop, but it weighs just 1.9kg, which still makes it lighter than most similarly spec gaming laptops on the market. The body of the Zephyrus G15 is made of a mixture of magnesium and aluminum, and the chassis is very hard.

There are more than 8,000 small holes in the lid of the laptop, and underneath are thin strips of prismatic film. I’d say it creates an interesting rainbow stripe pattern based on how the light hits it. To be honest, I like this better than the dot matrix display they released on the Zephyrus G14 last year. ASUS ROG Zephyrus G15 is also equipped with 6 speakers, two front tweeters, and a set of force-canceling woofers under the palm rest. Unsurprisingly, they sound great. The sound quality is clear, the bass is strong, and the percussion is strong. With Dolby Access, you can also jump between various equalizers. I can’t write this often, but Zephyrus G15 provides one of the best laptop audio experiences.

Battery life:

The G15 includes a large 90 watt-hour battery. As far as the cost of the laptop is concerned, it is great, but it cannot compete with it in this price range. I tested the battery using the Modern Office battery life test of PCMark 10, the PC was set to power saving mode, and Armory Crate was set to Windows mode. The IGPU mode is set to “Auto”, allowing the use of the RTX 3070. The external radio is disabled, the screen brightness is set to 50%, and the keyboard is reduced to the lowest backlight setting.

In this case, the battery lasted 5 hours and 1 minute. However, I noticed “this situation” because it can be expanded by changing some settings. Completely switching to the integrated GPU will definitely yield better battery life, as will reducing the screen resolution to 1080p. The versatility here is very good, allowing users to decide what tradeoffs they want to do. Due to the 30-minute half-battery fast-charging capability, the impact of a discharged battery is also less.

Keyboard and touch panel:

the keyboard gives us mixed feelings. Starting with the size of the key, this is only convincing when it comes to the master key. On the other hand, the arrow and Frow keys are very narrow. Not all users will like this design. In this way, for example, Left Shift and & lt stick directly. For the German model, the single-line Enter is also unusual. ASUS should also work on the label. Depending on the ambient brightness, the keys are almost unreadable when the backlight is turned on. At least, if needed, the backlight can be adjusted in several levels or turned off completely.

In addition, we describe the typing feel as very mild. The keyboard’s response to input is not particularly violent or particularly gentle. Practical: The sound can be comfortably controlled with special keys. ASUS’s large touchpad is commendable. 13 x 8.5 cm is rare in the 15-inch market segment; allows you to run long distances on the screen without having to restart your fingers. Thanks to the huge touchpad, the size of the palm rest is also very spacious, which is conducive to ergonomics. In addition, the smooth, easy-to-slide surface of the touchpad is impressive. There is also nothing to complain about multi-touch support (zoom and scroll with two-finger gestures). Only a loud and somewhat intermittent click is a disadvantage.

As long as you know that the GeForce RTX 3080 laptop version can only reach its potential to a certain extent due to ASUS low TDP settings, and it may be slower than the fast RTX 3070 laptop. ROG Zephyrus G15 GA503Q is a good figure. One of the highlights of the WQHD panel, because it attracts customers with 165 Hz, relatively fast response time, Free Sync, and good color space coverage. Other selling points are surprisingly rich sound, long battery life, and sleek design. In terms of appearance, the white version stands out from the competition. We do not like the noise level and keyboard layout in 3D mode. The fact that Asus skipped the webcam and soldered some RAM was also annoying.


Software and features:

Unfortunately, if you don’t have a built-in webcam, you can’t use the Windows Hello thing out of the box, but the power button on the Asus ROG Zephyrus G15 has a built-in fingerprint login. Many British media report software, McAfee is also the only real, movable criminal. The only other main software feature that needs attention is ROG Armory Crate, which allows you to control various performance settings of the hardware, as well as the RGB lighting of the keyboard.
