Help Why is my battery draining so quickly after putting music on my SD card?

I've got an LG G3 which was working fine. I got a new 128GB SD card though and after I transferred my data from my old 16GB card to this as well as a load of music, the battery life on the phone became ridiculously poor. It only lasts maybe 5 hours if I'm lucky when it used to last all day, sometimes 2 if I didn't use it much.

I tried reformatting the SD card and left it empty for a while and the phone worked fine. When I went back and added my music again though (not the old Android files I'd added before) the battery went crazy again. The top of the phone gets warm too.

I've looked at the Battery Usage and when I've got the problem the biggest battery use is coming from Android OS, with Android System not too far behind and Screen, which is as usual.

I tried SD Card monitor which was supposed to detect SD problems, but that didn't show anything.

I know people have had this problem before, but the answers have always been a bit all over the place, so I thought I'd open a new one specifically for my problem.

On other similar posts people have suggested that there's a corrupt file causing Android to get caught in a loop indexing it, but is there any way of finding out which file(s) is corrupt? I've got about 100GB of music so it'll be a nightmare to work out what might be broken through trial and error.

Thanks
 
If you can connect your card to a PC you could check it for errors. Did you format in the phone or PC? What file system? What class is the card?
 
I use a Mac (yet an Android phone - I got sick of Apple's over-priced handsets), but I assume I could check it there too. What sort of program should I be using to check it?

I formatted the card on the phone, just through 'Storage' in settings so I'm not sure what file system it used, probably FAT32 I imagine.

It's a 128GB class 10 San Disk Ultra micro SD card bought from a reputable company ( http://www.memorybits.co.uk/shop/mi...rosdxc-uhsi-memory-card-sdsdqua128gg46a/28451 ).
 
Hmm I have no idea how you would do it on a mac. Perhaps someone else will assist later
 
I ran it through the Disk Utility on my Mac and verified the disk. It said 'the volume appears to be OK'. Like I said, the micro SD doesn't cause any problems when it doesn't have much on it. It's just when I load it with music that it destroys my phone.
 
Some of the SanDisk cards are having problems with certain phones. You can check on SanDisk website.
Maybe you can try formatting to fat32 through windows and check if it work.
 
I've seen a lot of this before.

If you get a corrupted music file on your sd card, it drives the media management software trying to catalog things into outer space and your battery drops like a rock.

The way I've traced it is to copy over your music in smaller chunks of files or folders, wait, see if battery ok - if yes, proceed - if no - remove the last chuck, break into smaller chunks - repeat until you find bad file or files by process of elimination.
 
I was considering doing that EarlyMon. I might have to. I've got 100GB to get through though!

I can format to FAT32 through my Mac so I can give that a go too.

Cheers guys.

Reformatting to get the magical filesystem is overrated.

Android is going to mount it vFAT.

http://en.wikipedia.org/wiki/File_Allocation_Table (page search in there for vFAT if interested)

And despite what it says, nope, you're not going to get files above 2 GB.

I just let my phone format mine - but - I've formatted the smaller ones as FAT32 on a Mac before and they've worked just fine as well.
