manage to resolve mediaserver battery drain on my XZL.
Now battery is 45% compared to 20% previously with similar usage at 6pm.

Please refer to this link at XDA
Media Server battery issues on XDA

what i did

1. revalidate and fix all mp3 using mp3val
2. check all pictures - delete those corrupted pics ( pics that can't be viewed in album)
3. do the same for videos
4. put .nomedia files in all non media folders

a lot of work but worth the effort.
