Lenovo's 15.6-inch IdeaPad C340-15IWL convertible beats most office laptops in terms of battery life

With the IdeaPad C340-15IWL, Lenovo has a 15.6-inch convertible in its range. The 360-degree foldable IPS touchscreen display allows for various usage modes. Not only can it be operated with the fingers but also with the optional Lenovo Active Pen 2 (about 50 to 60 Euros (~$55 to ~$66)). The display provides stable viewing angles, a good contrast and a reasonably decent color reproduction. However, the maximum brightness is too low, and the color-space coverage isn't convincing either.
The convertible's highlight is the excellent battery life, which many office devices can't achieve. The backlit keyboard left a good impression too and proved its suitability for everyday use.
