Here’s something to get your teeth into. Over at LaptopMag, a whole host of Androids have been put through their paces in a grueling battery life endurance test. The goal was to keep the phones’ screens on while doing a moderate amount of processing, namely cyclically browsing a collection of web pages. Despite the supposed power savings afforded by AMOLED screens, the phones employing that screen technology fell quite a ways behind in comparison to the traditional LCD phones.
Why is that? AMOLED is supposed to only use up power on non-black pixels, right? Well, as LaptopMag points out, the majority of webpages are actually dark text on a light background, a scenario in which AMOLED actually uses more power than an equivalent backlit LCD.
