King of battery life.Toshiba's Skylake refresh edition of the Z40 business notebook is particularly convincing us with impressive battery runtimes. In our in-depth review, we check whether the very light and compact, and yet not exactly cheap companion meets the high demands of its target group.

Compact business companion. After recently testing the bigger Dell Latitude 14 E5470 extensively, the smaller scion is next in line. There is a big demand for compact devices that also always have enough computing power. Our test report reveals whether Dell successfully bridges the gap between computing performance and mobility.

Cool system. While the design of the Predator 15 is controversial, the cooling system is beyond any doubt. After the GTX 980M variant had to prove its capabilities at the end of 2015, we have tested the refresh with GeForce GTX 970M this time.

Too ambitious? The HP ZBook Studio G3 is the latest edition of the ZBook-series and follows the trend towards a slimmer device with powerful components. HP delivers a really good device in many aspects; however there are significant limitations in terms of emissions and the battery runtimes in particular.

Reliable Companion. A mobile 13-inch notebook should be highly reliable and also feature solid input devices to make the user's life easier. The E31-70 is Lenovo's affordable offering in this segment. This much we can say beforehand: the notebook meets most of the requirements.

Successful comeback! After the HTC One M9 came up short of expectations last year, HTC has made many improvements and now offers a great premium-range smartphone with a decent camera.

Just for starters. Lenovo's G51 shows just what is needed for first contact with the laptop world. The manufacturer presents a 15.6-inch device that unfortunately had to struggle with some shortcomings in the test.

New contender. EVGA shows the gaming notebook market how it's done with the excellent SC17. If first impressions are everything, then the SC17 is already hitting the ground running at full speed.

Daily companion. Large display, enough performance to handle the various daily tasks on might encounter and an attractive price point: Lenovo's IdeaPad 300 costs 450 Euro (~$500) and targets price-conscious consumers with basic needs.

4K rocket. In 2015, Acer created unique looking gaming notebooks with the Predator series. In order to not fall behind the competition, the manufacturer launches a refresh now, which is better than the old model in many aspects. We have reviewed an especially high configuration of the 17-incher.

LTE at an entry-level price. LG offers an affordable entry-level smartphone with LTE functionality for 119 Euros (~$133), dubbed K4 LTE. That is, however, its only highlight. The review sample makes a rather outdated impression in all other aspects. Have too many cutbacks been made?

Back to business. The latest edition of Dell's Venue 8 Pro presents itself as an extremely strong teammate in our test - thanks to the latest Cherry Trail platform in conjunction with generous dual-channel working memory. However, the colleague is not prepared to work overtime.

XL Size. The Shark 1 from the Chinese manufacturer Leagoo proves to be extra-large in more than one aspect. The decently-equipped middle-class smartphone with its 6-inch display and a weight of 241 grams is larger and heavier than most. In addition, it features a battery with a capacity of 6300 mAh - large by any standard. Among other things, we'll take a look at the battery life to see if it delivers what the capacity promises.

Fighting spirit. A small 10-inch convertible from Acer has high ambitions and turns out to be competitive thanks to a decent display as well as good input devices. Good: The 2-in-1 waives an active cooling solution and is therefore always silent.
