I had a media process that was draining my battery on my Bionic, I've heard of this problem on the nexus, the galaxy series devices, you name it... Problem: In applications>running, there is a process called MEDIA and when you click the process it says the process was started by an app, it also says download service & android.process.media....it causes your android OS to be significantly higher AT ALL TIMES than screen etc no matter what you do, it's a battery drain. The solution offered by all the other forums I could find suggested that this was caused by a corrupted media file and the solution was to remove all media from the SD card, then one by one, add a file then check running processes until you find the culprit! This is time consuming and I thought there must be a better way...so I did some digging and found a solution that worked for me and I wanted to share. First, this problem occured on my stock but rooted Droid Bionic, because I utilized an application that downloads mp3 files for free, it's a good app, it's not malicious by any means, but shotty programming from the app developer meant that failed files stuck, causing mayhem for my download manager... Solution: If you are running jellybean and notice the media process running and would like to end it's reign on your battery/ram...simply go to apps>all, scroll down to DOWNLOAD MANAGER, and click on it, scroll down to clear data and select ok. This won't harm anything, what it does is stops the media process from running a loop. I wanted to make this post so those out there like me who spent days trying to figure out the source of this running process could finally have an easy, viable answer! Cheers!
