HP EliteBook Folio 13.5 in review: Elegant convertible with a highly reflective display

Windows on ARM. The HP EliteBook Folio 13.5 has a high-quality build and is versatile to use. With Qualcomm's Snapdragon 8cx Gen 2, it's also one of the few devices that run Windows as an ARM version. Our review will clarify what that means in everyday use.

HP EliteBook Folio 13.5-3G2L2EA

With devices like the EliteBook Dragonfly Max, the Elite Dragonfly, or the EliteBook x360 1040 G7, HP has several more expensive convertibles in its lineup. This range is now expanded by the HP EliteBook Folio 13.5, which has the particularity of using an ARM processor. Besides the Qualcomm Snapdragon 8cx Gen 2, the configuration in review has 16 GB of RAM and a 512 GB SSD. The integrated Qualcomm Adreno 680 is responsible for displaying image content.

There are also other high-quality convertibles available for the price of approximately 2,600 Euros (~$3,052), and we'll use the selection below for comparison purposes in this review. However, since these are equipped with x86 CPUs, we'll also include the Samsung Galaxy Book S, which is equipped with the predecessor SoC of the Snapdragon 8cx Gen 2 installed in the EliteBook Folio 13.5.

Further devices from our database can also be added under each section.

Case - Convertible with faux leather cover

HP has made the case of the EliteBook Folio 13.5 from a high-quality imitation leather and, according to the company, from 90% recycled aluminum. This makes the outer surfaces feel a bit soft, while the display, which is protected by Corning Gorilla Glass 5, and the base unit dominate on the inside.

In laptop mode, the maximum opening angle of the Folio 13.5 is around 140 degrees. However, the screen can also be moved forward, so that it's positioned directly behind the ClickPad. The third option is tablet mode, where the back of the screen rests on the keyboard.

With a weight of 1.3 kg, HP's convertible is one of the heaviest devices in our test field. Only the Surface Book 3 13.5 from Microsoft is heavier. Compared to the latter, the Folio 13.5 isn't quite as wide, and it's also much slimmer, but it has a similar depth.

Connectivity - Only USB-C ports

The HP EliteBook Folio 13.5's connectivity is very modest. Apart from the two USB-C ports and the headset port, there are no other interfaces. Furthermore, one of the two USB ports is blocked by the power adapter when it's connected.

Nevertheless, the DisplayPort 1.4 and Power Delivery support enables the use of additional interfaces when the corresponding adapters or docking stations are attached.

Communication

The Qualcomm Snapdragon 8cx Gen 2 chip integrates Wi-Fi 6, Bluetooth 5.0, and 5G as wireless connectivity options. Instead of the latter, however, mobile connections are only available via LTE in the EliteBook Folio 13.5. With LTE Cat 20, download rates of up to 2,000 Mb/s and upload speeds of up to 300 Mb/s are possible in theory. The SIM card slot is integrated into the stylus compartment.

Once again, the wireless connection with our Netgear test router is expectedly weak, and this didn't improve in any of the multiple subsequent test runs. The Folio lags behind all contenders here.

Accessories

The EliteBook Folio 13.5 comes with the convertible itself, a 65-watt power adapter, and a stylus. Carrying cases and various docking stations can be purchased separately from the manufacturer. 

Warranty

HP provides a 12-month warranty period for the EliteBook Folio 13.5.

Maintenance

The HP EliteBook Folio 13.5 lacks standard maintenance options. However, as shown in the embedded video from HP, the interior can be accessed with the right knowledge, and the SSD can be replaced here, for example.

Input devices - No stylus included in the box

Keyboard

The Folio 13.5's keyboard offers clear feedback and is well suited for typing longer text. A two-stage backlight ensures that the characters are easy to identify even in low-light conditions. The up and down arrow keys are slightly smaller, which makes using them more difficult.

Touchpad

HP uses a ClickPad as mouse replacement; it's well-suited for navigating the mouse pointer, and it responds reliably both to touch as well as to click inputs. The touchscreen also responds reliably and immediately to touches. It's also less susceptible to fingerprints and can also be used for drag-and-drop motions.

Although there's a slot for a compatible stylus from HP, it wasn't available to us for this review.

According to our measurements, the Folio 13.5's display shows a good contrast ratio of 1,163:1 and an equally good black level of 0.215 cd/m². The color-space coverage could not be determined due to the incompatible measuring software.

However, the CalMAN analysis shows that colors are already reproduced with a small deviation out of the box. Therefore, performing a calibration is not necessary.

Display Response Times

ℹ
Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
   ↔    Response Time Black to White
27 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise
↘ 13 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 60 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (22.2 ms).
   ↔    Response Time 50% Grey to 80% Grey
44 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 25 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 68 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (35.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

ℹ
To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19025 (minimum: 5 - maximum: 3846000) Hz was measured.

The IPS panel of the Folio 13.5 is very viewing-angle stable. This allows viewing image content even from very flat angles without it becoming distorted or showing inaccurate colors.

Performance - Sufficient for everyday use

HP orients the EliteBook Folio 13.5 towards the use as an office device and for representative purposes. Our test device's configuration is a bit more powerful due to the increased RAM and storage capacity, but a model with 8 GB of RAM and a 256 GB SSD is also available.

Processor

The EliteBook Folio 13.5 is powered by a Qualcomm Snapdragon 8cx Gen 2, which is an ARM-based SoC like the ones used in current smartphones and tablets. Consequently, you can't run all the applications that are available for Windows, and you should check before buying whether the required x64 applications are also available as versions that can be run on an ARM processor. Nevertheless, most x32 applications should work.

Due to the problems mentioned above, it's not possible to run all the usual benchmarks. Therefore, we will focus on the executable tests for the comparison. These show that the performance of the Folio 13.5 is below comparable devices with Intel CPUs. Graphics performance is also significantly lower and consequently only suitable for simple photo editing and the like.

A comparison with the Samsung Galaxy Book S reveals that the Snapdragon 8cx Gen 2 offers about 10% to 15% higher CPU performance compared to the 8cx in most tests. Only in Geekbench 4.1 does the 8cx perform better.

The Adreno 680's graphics performance increases by over 40% compared to the predecessor, which is considerably higher. Compared with current internal graphics units, such as the Intel Iris Xe Graphics G7 96EUs, its performance is much lower, though.

In our CPU Benchmarks article, the Qualcomm Snapdragon 8cx Gen 2 can be compared with other processors. The Adreno 680's graphics performance can be compared with other GPUs in our GPU Benchmarks article.

Gaming performance

The performance of the internal Qualcomm Adreno 680 is only suitable for very simple games from the Windows Store. Other games, even older titles with lower graphics performance requirements, can only be run to a very limited extent or not at all.

Emissions - Silent Windows convertible

Noise emissions

The EliteBook Folio 13.5 is cooled passively and is consequently silent. We weren't able to detect other noises, such as coil whine or the like, in our test model.

Temperature

According to our measurements, the surfaces of the Folio 13.5 heat up to 35.4 °C (~96 °F) under load. As a result, the device only feels a bit warm, but it never gets hot. The palm rest temperatures always remain moderate, which allows the Windows convertible to be used at all times.

Battery life

The EliteBook Folio 13.5 achieves a runtime of 14:34 hours in our real-world Wi-Fi test. This is significantly longer than comparable devices with Intel CPUs and is only surpassed by the Samsung Galaxy Book S.

HP's convertible supports fast charging, which means that 90% of the 46 Wh battery's charge is available again after 90 minutes.

The advantages of a Windows-on-ARM device are clearly the frugal operation and the resulting long battery life. The HP EliteBook Folio 13.5 can be operated for a very long time of over 14 hours on Wi-Fi, and it has a high-quality build. The input devices are very good as well. We would have appreciated that there's an extra storage slot for the stylus, had it been included in the package in the first place.

The HP EliteBook Folio 13.5 convinces above all with its high-quality case and long battery life. However, we would have liked the included accessories to be more generous.

If we look at the system performance, the EliteBook Folio 13.5 can handle office applications, Internet usage, and possibly even minor image-editing tasks without issues. The system runs smoothly and responds immediately to inputs. Compared with similarly priced Intel convertibles, however, the available performance is clearly inferior to what these devices offer with their x64 CPUs. Nevertheless, the latter only achieve about half of the EliteBook Folio 13.5's battery runtimes.

If more performance is required, devices like the Microsoft Surface Book 3 13.5 or the Dell Latitude 13 7320 are recommended. If the longest possible battery life is preferred, though, and all the necessary applications can also be run on an ARM processor, the EliteBook Folio 13.5 is a good choice.

Price and availability

You can find the EliteBook Folio 13.5 in the manufacturer's online store starting at around $1,500 for the base configuration (128 GB of storage, 8 GB of RAM, 300-nit display, no LTE). You can also customize the device extensively here and max out the storage space, RAM, and the display brightness, as well as add LTE connectivity.

Alternatively, there are also a couple of listings of the device on Amazon and newegg, for example.
