If it seems that your mobile data usage doesn't seem to go as far these days, you may not be imagining things.Anyone that is actively using Facebook every day on their smartphones may find that it's a big reason why.If you've noticed that videos in your newsfeed automatically play as you scroll past, it can eat a hole in your data plan if it's not unlimited. Take a second to check the settings in your Facebook app specifically to check the Video Auto-play setting. When it is turned on, it is eating up your data plan when you are scrolling past the videos. If you enjoy the auto-playing of videos, you can change the setting so that it will only work when you are connected to Wi-fi only to preserve your mobile data plan. If you have no need to have videos ever auto-play, turn it off so that you have to tap the videos when you want to see them.Now if auto-play comes back, you will know that your default setting has changed. The link to change the settings is posted
