Fujitsu LifeBook T935 Convertible Review

Broadwell upgrade. Fujitsu does not hold back in its 13.3-inch LifeBook T935: A slim metal casing as well as a hinged display is configured with decent hardware, costing almost 2000 Euros (~$2244). However, the computer exhibits some weaknesses.

For the original German review, see here.

We now have the LifeBook T935, a new edition of Fujitsu's 13.3-inch business convertible. Outwardly, nothing has changed compared with the former LifeBook T904 model. However, the built-in components have undergone some modifications: The Haswell processors have been replaced by CPUs from the Broadwell generation. Our report reveals whether the LifeBook benefits from the new processors.

The LifeBook finds rivals in various device categories. Of course, convertibles like Lenovo's ThinkPad Yoga 14Dell's Latitude 13 7350Toshiba's Portégé Z20t-B are but a few of them. Tablets, such as Microsoft's Surface Pro 3, can also be named. However, even conventional 13.3 and 14-inch laptops, like Acer's TravelMate P645-S or HP's EliteBook 840 G2, are rivals.

Since the LifeBook T904 and the LifeBook T935 both feature an identical build, we will not go into details about casing, connectivity, input devices or speakers. The corresponding information can be found in the review of the LifeBook T904.

Display

The LifeBook T935 is equipped with a 13.3-inch touchscreen. It has a native resolution of 1920x1080 pixels. The laptop is also available with a WQHD touchscreen (2560x1440 pixels). The screen of our review sample has a very low brightness of 192.8 cd/m². Such a low rate is not sufficient for a portable laptop - especially when its screen is glossy. We would have expected a rate of at least 300 cd/m² here. After all, it should be assumed that a laptop would be used in a variety of light conditions.

The screen's contrast (836:1) and black level (0.25 cd/m²) do not give any cause for complaint. We cannot say anything about the screen's color space coverage because the measuring software crashed every time we tried. The screen's color reproduction is already appealing in state-of-delivery. Its DeltaE shift was 3.48, which just misses the target range (DeltaE less than 3). It does not have a bluish cast.

Fujitsu has equipped the convertible with an IPS screen. The feature of this kind of screen is its wide and stable viewing angles. Therefore, the screen remains legible in every position. However, the screen's low brightness and glossy surface make outdoor use impossible.

Processor

An Intel Core i5-5300U (Broadwell) dual-core processor beats inside the LifeBook. It is a frugal ULV processor that clocks at a base speed of 2.3 GHz. Its speed can be boosted to 2.7 GHz (both cores) or 2.9 GHz (one core). The Turbo is utilized in both AC and battery mode. The Multithread tests were mostly performed at 2.2 GHz. The processor sometimes accelerated to 2.7 GHz. However, the Turbo's utilization varied in every run, and thus the scores of the benchmarks we performed were different every time. We ascertained rates ranging from 2.47 to 2.71 GHz in the Multithread test of the Cinebench R11.5 benchmarks. It looked similar in the single thread tests with speeds ranging from 2.7 to 2.9 GHz. In our benchmark tests, the processor remained short of its potential because it could never max out its Turbo. We observed the same behavior in the LifeBook T904.

System Performance

Thanks to its strong processor and a fast solid-state drive, the laptop runs smoothly. We did not experience any problems. Overall, the PCMark benchmark scores are good, but they lag behind comparable laptops like the LifeBook S935. We see two reasons for this: First, the CPU cannot fully utilize its Turbo, and second, the working memory in the T935 operates in single-channel mode. The user cannot change either of these points because the LifeBook has only one working memory bank.

Storage Device

Fujitsu has installed a fast solid-state drive in the LifeBook. The SSD comes from Samsung and has a total capacity of 256 GB. The owner has approximately 200 GB available for use. The rest is reserved for the recovery partition and Windows installation. The SSD achieves good transfer rates. It is a 2.5-inch model (7 mm/~0.27 in height). Theoretically, replacing the SSD would be easy, but it proved difficult in practice. Since the LifeBook does not have a maintenance cover, the base unit's tray has to be removed for accessing the hardware. Even after removing all the screws, the tray still fits very firmly on both sides. Eventually we dispensed with opening the case to prevent damaging it.

Graphics Card

The LifeBook does not have a dedicated graphics card; Fujitsu relies on Intel's integrated HD Graphics 5500. The GPU supports DirectX 11.2 and clocks at up to 900 MHz. The 3DMark benchmark results are in line with the GPU's performance potential. It could achieve somewhat better results if the working memory in the LifeBook operated in dual-channel mode. However, this is not possible because only one working memory bank is available. The LifeBook T904 sister model still features the precursor of the HD Graphics 5500 core - the HD Graphics 4400. The new GPU offers roughly 10 to 20% more graphics power than its precursor. The graphics core is not only responsible for rendering graphics; it also unloads the main processor when playing videos. The processor's load is below 20% when playing a Full HD video (H.264 encoding).

Gaming Performance

The frame rates in games are lower than a comparably equipped laptop, such as the LifeBook S935 (dual-channel mode enabled), because the working memory in the LifeBook operates only in single-channel mode. Thus, even games with a low hardware requirement provide playable frame rates only in low resolutions and low quality settings at best.

Emissions

System Noise

The user of the T935 will be spared from any noise. The fan is normally inactive in idle mode. The convertible then runs silently. The fans increase their speed very slightly under load. We measured a noise level of 32.7 dB(A) during the stress test. Many other laptops achieve this rate just in idle mode.

Temperature

The LifeBook in the stress test
The LifeBook in the stress test

The CPU clocks at 2.3 GHz and the GPU at 900 MHz in the first few minutes, before throttling to 1.3 to 1.4 (processor) and 650 to 700 MHz (graphics core). These rates are maintained for approximately 30 minutes. The graphics core's speed drops to 500 to 550 MHz, while the CPU accelerates to 2.2 GHz. These speeds then remain stable. The LifeBook does not get excessively warm. The casing's temperatures come close to forty degrees Celsius (~104 °F) at two measuring points.

Energy Management

Power Consumption

Fujitsu's convertible did not display high power consumption while idling. We measured a maximum power consumption of 5.6 watts, which is a touch less than its T904 sister model. The energy requirement climbed to 38 watts for a moment in the stress test. Since both the CPU and GPU were throttled, the power consumption dropped to 22.8 watts. The power supply has enough reserves with a rated output of 65 watts.

Battery Runtime

The LifeBook achieved an idle runtime of 20:17 hours. Rivals such as Lenovo's ThinkPad Yoga 14 (12:17h), are depleted sooner. Idle mode is ascertained using the Battery Eater Reader test. The screen is set to minimum, the energy saving profile is enabled, and the Wi-Fi modules are off. The LifeBook shut down after 1:40 hours of load. We did not perform this test with the ThinkPad. The load runtime is measured with the Battery Eater Classic test using maximum screen brightness, the high performance plan, and enabled wireless modules.

The T935 stopped the real-life Wi-Fi test after 6:08 hours. The ThinkPad (5:25 h) is on par. In this test, websites are opened automatically every 40 seconds. The "Balanced" profile is enabled, and the screen's brightness is set to approximately 150 cd/m². We test the video playback time by running the short movie Big Buck Bunny (H.264 encoding, 1920x1080 pixels) in a loop. The wireless modules are disabled, and the screen's brightness is set to approximately 150 cd/m². The LifeBook managed a runtime of 5:35 hours. This test was not performed on the ThinkPad.

Overall, the T935's battery life is roughly on par with that of its LifeBook T904 sister model. Apart from the idle runtimes, the rates did not really impress us. We would have expected more from a 13.3-inch ULV convertible. Fujitsu does not have secondary batteries in its range.

The battery has a capacity of 45 Wh.

Verdict

Fujitsu LifeBook T935, courtesy of Fujitsu.
Fujitsu LifeBook T935, courtesy of Fujitsu.

The name of the LifeBook T935 does not immediately suggest that it is the Broadwell upgrade of the LifeBook T904. Fujitsu's 13.3-inch convertible features everything that is expected from a laptop: TPM, docking port, LTE. The installed processor is sufficient for everyday use. Unfortunately, it cannot develop its full potential. However, the laptop runs mostly silently and barely heats up. A fast SSD ensures a speedy system, and the input devices are impressive.

Despite the purchase price of just under 2000 Euros (~$2244), Fujitsu's convertible has weaknesses.

The battery life in our real-life Wi-Fi and video tests was good, but it is nothing to brag about. We would have expected a little more from a 13.3-inch ULV computer. The screen is not entirely impressive either. Although Fujitsu has installed a high-contrast Full HD IPS screen, it has a very low brightness.
