colinneagle writes "Consumer site MoneySavingExpert.com reported today that it has seen "many complaints" from users who believe a recent increase in data-related charges on their cellphone bills are the result of Facebook's auto-play feature. The default setting for the auto-play feature launches and continues to play videos silently until the user either scrolls past it or clicks on it; if the user does the latter, the video then goes full-screen and activates audio. The silent auto-play occurs regardless of whether users are connected to Wi-Fi, LTE, or 3G.
However, it's likely that Facebook isn't entirely to blame for this kind of trend, but rather, with the debut of its auto-play feature, threw gas on an already growing fire of video-sharing services. Auto-play for video is a default setting on Instagram's app, although the company refers to it as "preload." Instagram only introduced video last summer, after the Vine app, a Twitter-backed app that auto-plays and loops six-second videos, started to see significant growth.
