The battery-life from the new models of cell phones are underperforming their previous models, Washington Post tech columnist Geoffrey Fowler writes.

The details: Fowler performed the same battery test for 13 phones and his findings show battery life doesn't match up to what phone makers advertise. The new iPhone XS died 21 minutes earlier than last year’s iPhone X. Google’s Pixel 3 lasted nearly an hour and a half less than its Pixel 2.

Why it matters: Phone companies are trying to keep up with the demands of high-resolution screens, more complicated apps and "our seeming inability to put the darn phone down," per the Post. New phone features like better processors, low-power modes and AI have tried to keep battery life under control for users.
