Fujitsu LifeBook P728 (i5-8250U, UHD620) Laptop Review

Mike Wobker, 👁 Sebastian Jentsch, Stefanie Voigt (translated by Mark Riege), 06/07/2018

Convertible without compromises. With the LifeBook P728, Fujitsu has a convertible for business users in their product line that not only includes numerous security features, but is also upgradeable. Our review clarifies what to expect from the small workhorse with Intel's Core i5-8250U processor.

For quite a while, Fujitsu has proven itself as a consistent manufacturer of business devices. Aside from having some minor weaknesses, these are mostly devices that can be maintained easily and ensure a good system performance. We had a similar impression of the LifeBook P728, which can be transformed from a full-featured Ultrabook into a usable tablet within seconds. On top of that, the Japanese manufacturer also includes a stylus with various tips.

Combined with the equipment inside, we do not notice any faults, at least not on paper. An Intel Core i5-8250U CPU ensures sufficient computing performance, supported by a UHD Graphics 620 graphics unit. Together with 8 GB of working memory and a 256 GB SSD, smooth operation of most office applications is ensured.

We do not find many competitors in the price range of our test unit of about 1500 Euros (~$1766; $1299 for preconfigured version in the US; starting at $1764 to customize it). Therefore our comparison list includes convertibles within a larger price range between 1000 and 2000 Euros (~$1178 - $2355) and a comparable performance. These include the Lenovo ThinkPad X1 Yoga 2018, the Acer's Spin 5 SP515-51GN, the Asus Transformer 4 Pro T304UA, and the HP Spectre x360 13.

Case and Equipment - The Fujitsu convertible has a robust case

Fujitsu has constructed the tops of the base and lid from metal, while the bottoms are made from a robust plastic. The selection of materials communicates robustness, and accordingly our test unit resists attempts of twisting it. Only the display can be bent with some use of force when it is opened.

All the control elements including the power button are on the sides of the device and can be easily reached. Only the fingerprint sensor has been placed below the keyboard. Correspondingly, you always have to put the convertible in laptop mode before you can unlock it via fingerprint. The USB connections, only one of which is USB 3.1 Type-C, offer a good connectivity.

You can fully insert storage cards into the integrated SD card reader. While the Fujitsu P728 achieves good read and write rates of about 70 MB/s using our reference storage card, it is significantly slower than for example the ThinkPad X1 Yoga from Lenovo.

In addition to using LAN and WLAN, the LifeBook P728 can also connect to the external world via Bluetooth 4.2 and LTE. The integrated mobile modem supports the LTE Cat. 6 standard, which allows transfer speeds of up to 300 Mbit/s during download and 50 MBit/s during upload. The Fujitsu convertible also offers fast WLAN, and thanks to the fast ac standard, transfer rates of more than 600 Mbit/s are possible.

The only negative point is the webcam, which only takes bad recordings at 0.9 MP. During video chats, your own picture looks very blurry and the transmissions are slightly delayed.

Input Devices - P728 has a bad touchpad and good touchscreen

The regular keys of the P728 have a comfortable size and the smaller special keys are also easily reachable. However, things are very tight between the arrow and page up/down keys and you can easily hit the wrong key. While the pressure point can be noticed clearly, it turned out a little too soft.

Things look different in the mouse substitute. Although the separate keys have a good pressure point throughout and produce a comfortable click, the touchpad itself reacts very sluggishly and often does not register tapped mouse clicks at all. The battery-operated stylus offers a good alternative here. It can be placed into a slot in front on the right side, where it can be transported and charged at the same time.

The touchscreen responds to stylus input very well and the mouse pointer already moves ahead before the tip even touches the screen. The screen also responds very well to finger taps.

Display - The LifeBook P728 display is flickering

The Fujitsu LifeBook P728 displays its image content on an IPS panel with a resolution of 1920x1080 pixels. As an alternative, Fujitsu also offers a TN panel with a 1366x768-pixel resolution. In addition, the buyers also have a choice between a glare and non-glare surface. In all versions, the brightness is supposed to be above 200 cd/m², with the IPS technology being the most powerful at supposedly about 260 cd/m².

Our measurements confirm this specification, at least for our test model. In the center of the screen, the display of the LifeBook P728 even achieves almost 300 cd/m². However, the brightness distribution is very uneven, and for example in the left center of the screen the brightness is almost 70 cd/m² lower. Moreover, the Fujitsu uses PWM for adjusting the brightness. At a brightness of below 80%, the relatively low frequency of 250 Hz causes sensitive eyes to feel irritated quickly.

Display Response Times

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
23 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 10 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 28 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 19 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 35 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41.1 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

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 detected 250 Hz ≤ 80 % brightness setting

The display backlight flickers at 250 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 80 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 250 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8677 (minimum: 43 - maximum: 142900) Hz was measured.

Color Space Coverage sRGB: 63%
Color Space Coverage sRGB: 63%
Color Space Coverage AdobeRGB: 40%
Color Space Coverage AdobeRGB: 40%

Fujitsu uses a rather bad display for this price range in the LifeBook P728. Of course, a black value of 0.36 and an sRGB color space coverage of 63% are not extremely bad. But considering the price, the competitors offer considerably more here. At 828:1, the contrast ratio in particular is below that of the other convertibles in our comparison.

Outdoors, the Fujitsu LifeBook P728 can be used as long as you stay in a shady place. Even though the display of our test unit has an anti-glare coating, it cannot overcome the reflections.

Our test unit is equipped with Intel's Core i5-8250U with integrated UHD Graphics 620 and 8 GB of working memory. Fujitsu also offers the options of a Core i3-7130U, Core i5-8350U, and Core i7-8650U processor for the LifeBook P728. While the Core i3 is recommended as more of a budget variant, any CPU of the 8th generation can be used in the office environment without any concerns.

While the working memory can be expanded up to 16 GB, there is only a single RAM slot, so it can only run in single-channel mode. A maintenance hatch at the bottom allows not only accessing the RAM, but you can also replace the SSD in this way.

Processor

The performance of the Intel Core i5-8250U in the CinebenchR15 benchmark does not live up to its potential. Its performance in the LifeBook P728 is clearly below the average of other devices with this CPU. On the other hand, the performance delivered can also be maintained for longer periods of time. While there are often minor performance drops, the system is able to quickly recover from them.

System Performance

While the Fujitsu convertible also remains below its potential in the PCMark-8 benchmarks, we have nothing to complain in terms of system performance from a purely subjective point of view. The operating system runs smoothly and the users do not have to wait when opening files or wait only briefly when starting up programs.

Storage Solution

The built-in storage also achieves significantly lower values in some parts than the comparison devices in our benchmark tests. Despite these differences, the built-in Micron-1100 SSD is still faster than conventional HDDs, which is mainly reflected in a smooth system operation. The operating system boots up very fast and the users do not have to live with long wait times when opening files or such.

You can read up on the performance achieved by other storage solutions in the benchmarks in our SSD/HDD benchmark page.

Graphics Card

The UHD Graphics 620 from Intel takes care of the display of graphical content in the Fujitsu LifeBook P728. This integrated graphics card has a clock speed of up to 1150 MHz (boost) and benefits considerably from the built-in working memory. Since in the LifeBook P728, this can only be run in single-channel mode, the available performance is correspondingly lower.

In the 3DMark benchmarks, the graphics unit in the LifeBook P728 performs on a good level and achieves about the average result of all the devices with the UHD Graphics 620 that we have tested. Looking at the result of the ThinkPad X1 Yoga, you can see that the convertible with dual-channel RAM achieves about 10% more performance than our test unit. Thus the performance loss of the Fujitsu P728 due to the lack of a second RAM slot remains within limits.

You can find out the performance of other graphics cards compared to Intel's UHD Graphics 620 on our GPU benchmark page.

Gaming Performance

The integrated graphics card of the Fujitsu LifeBook P728 is only suitable for older and casual games. In our test unit, the already five-year old "BioShock Infinite" runs smoothly only in the lowest graphics settings. Since the Fujitsu convertible has not been designed as a gaming device, the lack of the graphics performance should not surprise anyone.

You can check on our games benchmark page, which games run smoothly with Intel's UHD Graphics 620.

As with most of the devices of this kind, our Fujitsu LifeBook P728 is very quiet. During normal office operation, you do not hear the convertible at all, and it also always remains whisper-quiet under load. Thus the device is well-suited for work in very quiet surroundings.

Temperature

Stress test
Stress test

The LifeBook P728 hardly warms up during idle, and the surface temperatures always remain below 25 °C (77 °F). However, under load the values rise above the 40-degree mark (104 °F), but these temperatures are only reached in the back area of the convertible. So you can still use the laptop on your thighs, and the palm rests remain comfortably cool.

During our stress test, we put a full load on the system and test whether the Fujitsu P728 can maintain the performance of the CPU also over a longer time period. It shows that the clock speeds have dropped to below 400 MHz after about 20 minutes, so it dropped significantly below the base clock speed. Since such a load is almost impossible during everyday work, you still should not expect any limitations due to the temperatures being too high.

Speakers

The speakers of the Fujitsu P728 should only be used if you really have no other choice. Beginning already from the high mids, the sound spectrum drops drastically, causing only high and very high tones to remain. The result is a very shrill sound that also sounds scratchy at high volumes. You definitely should always use external speakers or headphones to play audio content.

Power Consumption

In terms of the power consumption, the Fujitsu convertible shows itself as a very energy efficient device. During idle, we measure a maximum of 7.3 watts, making the P728 into one of the more frugal representatives of its kind. Our test unit also remains undemanding under load, not rising above a power consumption of 30 watts. Thus the included 65-watt power supply should be sufficiently sized to be able to provide the LifeBook P728 reliably with power.

Battery Life

In our practically relevant WLAN test, the LifeBook achieves a solid battery life of 5.5 hours. Although you cannot get through a work day with this, you don't always need to look for an outlet immediately. However, in the comparison with the average battery life of convertibles, the Fujitsu P728 must be called below average.

- sluggish touchpad
- bad speakers

Verdict - The LifeBook P728 is really great, but ...

Our test unit was provided by Fujitsu Germany
Our test unit was provided by Fujitsu Germany

In our test, the LifeBook P728 from Fujitsu is able to prove that it is suitable as an office convertible. In particular, the many connections and security features are hard to find in this format with other manufacturers. This makes it even more incomprehensible that Fujitsu messes up in the input devices and loses the chance to deliver an all-around good device.

Although the LifeBook P728 does not live up to its potential, it offers many connections and security features that make it into a good alternative for office users.

While the benchmark results of the LifeBook P728 are also not outstanding, they show that there is enough performance to do some work with the convertible. Our subjective impression also speaks for the Fujitsu device. A smooth system performance and virtually no wait times ensure a fast and uncomplicated operation. In addition, Fujitsu is not too stingy and includes the in-house stylus with various tips directly in the package.
