[Q] battery drain due to sd-card presence? - Galaxy S II Q&A, Help & Troubleshooting

Hi,
I traced an accelerated battery drain on my -now again stock JB- Galaxy S2 to the presence of the extra microSD card
I setup the phone for miminal service as to save battery.
With the sd-card present, the phone completely discharges in about 16 hours - while having it on standby.

When the sd-card is removed, depletion rate is much slower
Over about the duration 16 hours, only 10% has gone! Although 5 days would seem very optimistic, but I'll take it
As far as I can see, nothing really should use the sd-card - it's empty.
reformatting the card has not helped.
What is causing this and how can I stop it - bar from removing the sd-card permanently?

What sd card are you using ?
Do you tried to disable media scanner?

thanks for your reply
card is kingston 8gb SDHC class 10
I can disable media storage, but for disable media scanner I need some apps and root the phone ?
I'll come back with further updates

Scan .nomedia files on the memory card and delete them.
Secondly, if younhave stored any mp3 scan them and if found any broken mp3 delete or repair them

Yep it needs root for disabling media scaner but try to check and fix broken mp3's
For me i have this problem only in cm based roms and on stock i dont have

I guess you have not named your memory card. Of so just delete the name.
Did u scan for .nomedia files?

Have you tried CPU Sleeper?
http://forum.xda-developers.com/showthread.php?t=1745516
I used to have similar problems that you are currently having, but they stopped after installing that app. It does an awesome job of preserving battery life when the phone is on standby. I also used Titanium backup to freeze some apps that I dont use. The list can be found here:

I am running the Rogers stock rom (rooted) + CPU Sleeper. Feel free to PM me if you need more info or have any questions.
Been playing around more it seems to be the root causing it.. what root are you using?

I use cm10 latest nightly with regular overclocked kernel from Johnsel
Try attaching a usb mouse or usb keyboard and see if it work
Try attaching a fat formatted usb stick not ntfs formatted one
Try a different usb stick if you can
Do not try a usb powered hard disk but you could try external powered hard disk
Try app from google play called paragon to mount the usb stick esp if formatted ntfs
Try fat formatted sd card
Open setting/storage and go down (lower than sd card list) and see if the usb stick is mounted if not click mount and see
Try app like astro file manager to try to access the usb stick files click up in it and see the usb directory

I have eclipse 2.3 installed on my x2 and am having sd card/storage issues. As you can tell from this screenshot, it appears that my phone is recognizing my sd card as internal memory and internal memory as sd card. I have an 8gb card and I realize that it is almost filled because I downloaded a game and a movie onto it. When I open my file manager, it says that they are on my card, but my phone is telling me that my internal memory is almost full. Any help would be appreciated.

So you are talking about your memory and not your physical storage space on your 8GB storage card? Obviously, as you mentioned, your card is pretty full which could cause it. Also, you can try just going into recovery and wiping cache and dalvik cache and see if that cleans up some stuff. Some apps keep a lot of cache on the storage space.
The problem that I have is not the lack of storage but as to why my phone is calling my external storage internal. Meaning my internal and external are swapped.

SD flip is a standard feature of eclipse
Sent from my DROID X2 using xda app-developers app
Oh, I thought you knew that part already. lol. Yeah, Eclipse switches your storage locations so you have more internal storage which is better. All your stuff on your external card is still on your external card, but the mod makes your phone think its the other way around.
Is there any way that I can reverse this?

You can see her yourself that which app is using how much space in your phone.
So uninstall the ones which are using very large amount of space.
If it doesn't work then try cleaning cache and dalvik cache..

Maybe it is possible that your internal memory is used as sdcard and the sdcard is used as usbhost..

Hmm seems odd since that's the space were ONLY apps are located in.
Are you rooted? Cause then you could re-flash your ROM and chack again.

Running out of System Space?

My phone keeps telling me it's running out of System Space but when I go into settings and look at the storage settings it shows this.

Look for recovery backups in data-media.
Available internal storage too low. If it gets below 375ish you'll get that notification.
Sent from my Optimus G using xda app-developers app
But look at how much available space the bar shows, and I added up all the "used" space and it's just under 8gb. Also no recovery backups :/
Sent from my Optimus G using Tapatalk
Did you hit refresh next to the bar graph or power cycle? The categories below that won't show all data on the internal sd, there are partitions and hidden files and folders that don't factor in to it, it'll never equal the 11.30 gigs.
Sent from my Optimus G using xda app-developers app
Yes I did refresh and yes I have power cycled, I have tried flashing different roms, completely formated my internal before.
Sent from my Optimus G using Tapatalk
And I know it won't be exactly equal, but it should be close right? Not many gbs off...
Sent from my Optimus G using Tapatalk
Not necessarily, there can be quite a discrepancy...
Sent from my Optimus G using xda app-developers app
If you have games that store a lot of data, or download a bunch after install it won't show in the settings screen.You may find it in android-data or android-obb.
