Based on our WLAN tests, the cheaper IPS configuration can outlast the more expensive OLED configuration by almost 4 hours when browsing the web at identical brightness levels, identical web pages, and identical power profiles each.

Misleading article, OLED compared to standard IPS is more efficient at lower brightness, however becomes less efficient as the brightness and screen size increases, where there is a distinct tipping point when it becomes exponentially worse than IPS. But this is not the case on current laptops in which the brightness and size of the best Samsung OLED panel maxes out at only 500nit and 15 inches.

The real issue with the 13.3" Spectre is the pixel-dense 4K UHD resolution running on a relatively small 60Wh battery, not the use of OLED technology.
I got 7 hours of use out of my previous Spectre 13.5" with 2.5K QHD OLED paired with a bigger 67Wh battery, which would probably translate to roughly 8.5 hours in your WiFi 1.3 Browsing test, pretty decent by your review standards.

An accurate comparison of IPS and OLED should be performed with 1080p IPS and 1080p OLED models of the Spectre 13.3 using the same CPU/RAM/Storage SKU, under equal settings. And it CAN be done, since the HP Spectre x360 13.3" is the first laptop to offer IPS and OLED touch panels in an identical 1080p resolution.

I think OLED is less efficient that LCD because most computer content has white backing.

But you are right. I have a OLED XPS and if you set the 4K resolution to 1080p/2K  then the battery life goes from 4hrs to 10hr+. There's also little change in sharpness of the screen.

I agree completely, this is a very misleading article. The journalist does not understand the difference between 4K vs 1080p, and IPS vs OLED.

Very shoddy piece of misinformation, but as always, vigilant readers are ready to point this out in the comments section. This author has a habit of misleading readers, but he does not understand that he is tarnishing his image. Even a chutiya can write better and to the point articles.

...yeah, everybody else caught the issue already. Just add the Spectre x360 14 OLED to the comparison using the tool.
