LONDON:-Smartphones get more and more sophisticated every year, from flashy edge-to-edge screens and facial recognition to professional-grade cameras. Despite these high-tech upgrades, it seems battery life hasn't gotten quite the boost many would have expected to arrive by now. That's according to a new study by The Washington Post, which found that battery life in many handset makers' flagship phones suffered compared to older models.

 

The Post conducted a series of battery life tests on 13 phones, including the new iPhone XS and Google's Pixel 3.

A light meter was used to make sure that every device was set to the same brightness.
