MagyarReview XIDU PhilBook Max Convertible: Dark touch screen and little performance
Case, equipment and input devices
The dark grey plastic case of the XIDU PhilBook Max meets the expectations of the price range. The workmanship is fine and you don't have to worry about the stability in everyday use. Only the two hinges should be a bit tighter. Very good: On the bottom, there is a maintenance flap for access to the M.2-2280-SSD.
With two USB 3.0 ports, the microSD reader and the mini HDMI output, you should get along well in everyday use. The WLAN module from Intel (Wireless-AC 3165, 1x1) is very reliable and we didn't notice any problems. We also like the keyboard very much. The key stroke isn't very long, but the keys don't rattle around and there's a lot of feedback. Thanks to the two-stage backlight you can still see something even in dark environments.

Display - PhilBook with dark IPS panel
The 14.1-inch IPS screen is highly reflective due to the touch screen. That's not unusual, but in combination with the very low brightness of an average of just 175 cd/m², the image often looks too dark even in bright interiors. In the open air you can completely forget about the use. However, the subjective image impression is still fine, which is due to the very good contrast ratio. Screen bleeding is no problem for the panel. All in all, the competition offers much brighter screens in the price range of 400 Euro.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 25000 Hz | ≤ 20 % brightness setting |  |
The display backlight flickers at 25000 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 25000 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18889 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Performance, emissions and battery life
The performance is certainly one of the biggest problems of the PhilBook Max. The Intel Celeron processor offers very little performance with its two cores (2 threads). In the best case this is enough for demanding activities (writing e-mails, surfing), but when running applications in the background it becomes problematic and the system reacts much slower. Multitasking should also be avoided.
The processor also has a clear disadvantage in a competitive comparison, even the much cheaper Medion Akoya offers more performance. At least the PhilBook Max is passively cooled, so it's always a silent device.
Thanks to the integrated video decoder, the playback of high-resolution videos is not a problem. On the 128 GB SSD (M.2-2280, SATA-3) the user has about 97 GB at his disposal. The transfer rates are not particularly high, but at least better than with conventional HDDs.
The WLAN runtime with a brightness of 150 Nits is almost 6 hours, with full brightness it's only 5 hours.

Pros
Cons
Verdict
The XIDU PhilBook Max is currently available for around 400 euros. It comes with a 14.1 inch convertible with a neat case, practical input devices and the most important interfaces. But the two big weaknesses are the display and the performance. Although it is an IPS screen with an actually decent picture impression, the brightness is very low. Together with the reflective screen surface, it is hardly possible to use it in bright rooms or even outdoors.
It is also important to be clear when it comes to performance that the planned tasks must not be too demanding. When updating or installing, the device is fully loaded, so you can forget about multitasking.
Low performance and dark display: The PhilBook Max offers some positive features, but performance is often the limiting factor. Here the competition simply offers more.
The price is still too high in our opinion, at just over 400 Euros. Especially from Chuwi there are better offers in this segment or even for less money.
