Temperature & Noise
Temperatures when idle are generally cool. When running intensive apps, the laptop gets hot in areas such as under the screen and the base area. Fortunately, the palm rests and the keyboard stays cool even under heavy usage.
For heat dissipation, the UX371 uses a single dedicated fan. It stays quiet as long as you use the default Windows power plan but picks up rather quickly on other modes.
Upgradeability
Access to the internal components requires loosening 9 Torx screws found at the base. The memory is soldered on to the motherboard and the only the SSD can be upgraded on the UX371.
Software
The UX371 comes with the standard MyAsus app which let’s you control power profiles, battery and screen settings, updates, etc, while the Audio is controlled using AudioWizard.
Audio
There are two stereo speakers located on the lower front edge and directs the sound towards the bottom. one on each side, with an output of 2 watts. The speakers are loud enough to fill small to medium-sized rooms with minimal distortion, but they lack bass.
The quality is good for calls or conferences, while media playback will be better with headphones. There is no 3.5mm port on the laptop and the included USB-C adapter needs to be used to connect the same.
Battery
The UX371 packs a 67Wh lithium-polymer battery and promises an incredible battery life of 10 hours on a single charge and can quick charge up to 60% in just forty-nine minutes.
Based on the usage and screen brightness, the UX371 lasts between six to nine hours. When browsing the internet, you can expect around eight hours of battery time.
In terms of charging, it took 1 hour 30 minutes to charge back from 0% to 100%. One thing to note here is that the power adaptor is very compact and short, it can send the laptop flying if you are not careful with the cables.
| Idle (one third brightness, no WiFI) | 9h 40 min |
| Web Browsing (one third brightness) | 8h 32 min |
| Video Playback (one third brightness) | 7h 12 min |
Verdict
The ZenBook Flip S is a premium 2-in-1 ultrabook with a fantastic 4K OLED display, brand-new Tiger Lake processor, great build quality and decent battery life.
In terms of performance, the new Core i7-1165G7 is great for everyday tasks and work. The only downside here is the price, there are really some good 10th-gen Intel and Ryzen 4000 alternatives currently available for much cheaper, although not as stylish or slim.
