HP has launched a new laptop aimed at business execs, claiming the world’s longest battery life… for a 13-inch business convertible. As standard, it lasts up to 16.5 hours, but an optional Performance battery boosts this to over 24.5 hours.

Weighing a fraction less than a kilo with the standard battery the Elite Dragonfly is an attractive-looking 2-in-1 laptop whose screen folds back behind the keyboard for those times when you want to use it as a tablet. It’s also compatible with HP’s Active Pen G3, allowing you to sketch and scribble notes on the screen.

It’s one of the first laptops to meet the criteria for Intel’s Project Athena program, which is essentially a template for what next-gen laptops should be like.

As well as light weight and long battery life, it also means good performance and security. And to this end, the Dragonfly uses 8th generation Intel Core vPro processors (i3, i5 and i7) and has built-in Wi-Fi 6 for a faster connection where a Wi-Fi 6 hotspot is available.

There’s also a fingerprint scanner for authentication and the option of a SureView Gen 3 privacy screen which prevents other people seeing what’s on the screen. A physical shutter prevents anyone abusing the webcam.

There are a few display options: the privacy screen has a 1080p resolution and a high brightness of 1000 nits. A 400 nit 1080p screen is a second option and will mean better battery life. Last, there’s a 550 nit 4K option, but that will be more power-hungry.

4G is also optional, but will be essential for some mobile workers. Ports include two Thunderbolt 3, USB 3.1, HDMI and a headphone jack.

Accessories include a sleeve, a Bluetooth Travel mouse and a Thunderbolt dock.

The Elite Dragonfly will start at £1099 / $1549 and is expected to go on sale from 25 October. You can find out more about the Dragonfly on HP's website.
