LG G3 Easy Fix For Battery Drain - G3 General

I was having a problem with an unusually high battery drain with my LG G3. I also began to notice a few corrupted images.
So I turned my G3 off and removed my microSD card. I inserted it into a USB microSD card adapter & plugged it into my PC.
I ran a check on the card using DiskGenius (free) and saw it had some problems. My solution:
1. Used DiskGenius to fix exFat file system problem (not perfect).
2. Backed up all the files on my microSD card to my PC using EaseUs Todo Backup (free)
3. Formatted the card to exFat again using the SD Card Formatter (free)
4. Restored all my files back to my microSD card.
Now my battery life is amazing again and any app that accesses the microSD card is faster!
Hope this helps some of you.

Thanks for the tip but, honestly, I don't understand how that can justify an improvement in battery life. Could you elaborate a bit more the idea behind it?.

The file system on the microSD card can get corrupted. When that happens and the phone tries to access a corrupted file, it might take multiple file reads (to compare the results of reading the same location) and/or more CPU cycles (performing error correction) to read the file, either of which drain power from the battery.
Corrupted files can also cause certain apps to crash.
Also, depending upon what version Android you have, sometimes when the Android media scanner encounters a corrupted mp3 it will scan the file over and over, draining the battery (this is a common problem).
Note that what I'm suggesting in my OP does not fix the corrupted files, it only fixes the cause (exFat file system corruption). The corrupted files must still be fixed or deleted.
Reformatting your microSD card should be done whenever there is a sudden and unexplained power drain, or once every three years.

Good finding then. Glad if it worked for you. I'll take it into account when it happens to me. Thanks.

I was also having problems with my Kindle app, books taking a long time to open and close. This fixed it fast!

I fixed it in another way. I bought a 7500mah battery ;P

Assuming it is a real 7500mah battery, that fixed the battery drain symptom, but not the file corruption or device slowdown.

That is actually a great thing to remember if having SD card issues, much appreciated.
However the title seems to be misleading. Even if there was a corrupted file on the SD card, it would not cause a significant impact on battery usage. I guess maybe if a poorly coded app (ie: with no error catching) continuously tries to access a corrupted file, maybe. But even then... I just don't see it. Also, quality and fast SD cards are so cheap now, I think a more practical solution would just be to replace the card.

A corrupted SD card can cause significant battery drain for the reasons I already explained. Besides myself, others have already experienced this problem espcially if an mp3 file is corrupted.
I replaced my SD card with a bigger one, but some people can't always afford that.

X2 beware it CORRUPUTS memory card content!

People beware!!!
This failure X2 corrupts memory cards!
Completely corrputs the content!
Sooner or later you’ll also encounter this –
confirmed by many other users!
So if you still decide to use this unreliable piece of failure,
be sure to make backups!!!!

Indeed,
I lost 7Gb aprox of very valuable stuff, like source code, documentation, photos, charts, music, software, video, backups, and so on..
I think i may found the pattern (kind of) because after the first corrupted memory it happend to me seeeeeveral times...
Its like if i start an app (lets say a game) that uses a lot of resources, the game is laggy and somehow it closes OR you use another app on the same time that is installed on the SD, like they crash by sharing some kind of resource... im not quite sure but at least two times after "playing" (i quote it because its mega laggy) i saw my Program Files folder EMPTY...
At least this time it doesnt f*** the whole card..
i wonder why OP hasnt posted a single good thing bout x2
i owe it and im quite satisfied with it it hass some things that need to be fixed but otherwise i like it
the only problem i have with it is that loses the sd card sometimes but as i read its the card problem (default one that came with it) its class2 (cheap $#"$#!%%&Z&#&"%%""% provider)
indycar: You are terrible wrong! The card problem issue is the X2 problem NOT card! I try a lot of cards (differents manufacturer, size, class). The point is, that X2 automatically turn off card when you stand by device and it turn on when you wake up X2 again. I´m thinking, that this should be a "feature" to increase power managing capabilities...

Well I wrote many good things about it before.
With a decent firmware it'a decent device and the best choice!!!!!!
But current firmware is a massacre confirmed by all users so no reason for good words....
The memory card problem is completely independent from the card, happened to me with both cards!!!
Another victim of memory card corruption. the whole content of the memory card just dissappear like*poof*. and the symtoms looks the same. system became incredably laggy all of the sudden. reboot the device and "watch your past disappear" (adapted from STFirst Contact when Borg Queen says "Watch your future ends")...
Ben
the weird thing about my card is that only SOME things disappeared, i had several folders on my card little by little they disappeared but the files that werent in folders stayed and never got deleted, thought the card itself did not gain/lose any memory.
my card is fine .. nothing happened
You corrupted people should try some file recovery software to recover your card content. There are plenty of free recovery programs on the internet. You'd have to stick your card into your computer and run the software on the disk. Report back if you get it to work because if could help others.

Most of my content was backed up so I will not hassle with this.
However I would love to know how to eventually format the card to
to not to slow it down...
This whole X2 case reminds me of N97 when it was introduced. Truly 'spooky' phone
My card is also from today one of those who messes up. My files does not get deleted but when browsing the card from the phone it sometimes contains perhaps two out of the folders, sometimes the files is there (i guess) but folder and file names seams renamed. A look at the card on my computer shows every file/folder/file name intact.
Guys,
You who had the SD-card corrupted, did you install any applications on it that you use frequently?

As you might have read, my card only looked corrupted in the phone file explorer but yes, I installed every application on the card. Most used is S2P and Pocket player and of course all my music used by the apps mentioned.
If running S2P listening to music,the app suddenly halts. I then shuts S2P down and starts file explorer to see what happened the card looks partially deleted or all folder and file names corrupted (mounting the card on PC shows no errors at all).
In the beginning I had Outlook save incoming mail on card but as the card disconnects outlook creates a folder, Storage Card in root of phone. That creates a problem when the phone mounts the card again since it gets named Storage Card2 instead. That messes up all short cuts created by me or phone to the applications installed at the card.
I use card pre packed with phone and I see no reason to try another since others here reports no difference when replacing card.

The moment my card got corrputed
I quit using X2 completely.
I've seen no sense in further struggling and
I also have no time for that.
Why the question?
MR2 also screws it?!
TLDR: Don't install programs or attachments on your storage card.
I am now 100% certain that power management is behind the disappearing storage card issue, and is a culprit in a number of other bugs. It looks like when you put the device into standby, it switches off power to a number of components.
It's easy to see what happens with the storage card if you use SPB Mobile Shell. There's a handy shortcut under Tools - Browse Files - Storage Card. If you put that shortcut on your home screen and come out of standby, you'll usually see the icon return to the default unassigned shortcut. After anywhere between a fraction of and many seconds, the SD card icon will reappear.
Seems like some genius engineer at Foxconn, not knowing much about WinMo or stuff in general thought he was being very clever by saving what, 10mA? in shutting it off. Think of all those extra minutes of standby time saved.
I too suffered from a corrupted FAT, but thankfully all I really lost was MP3s I already had elsewhere. Since I figured out what's going on, I've had no trouble whatsoever. It does of course mean that I've had to make yet more compromises in the functionality of the device. The key is to make sure not to install programs on the storage card, or if you must, make sure the phone doesn't go into standby while running them. Also, don't choose to store email and MMS attachments on the card, or you'll get the Storage Card2 problem.
Stupid power management also explains these other things that have been bothering me, and many of you:
Notification sounds and lights not working properly.
Sporadic checking of email.
Custom ringtones disappearing (Hint: put them on main memory).
The phone randomly freezing when trying to work with Bluetooth car kits.
Presumably Sony engineers are aware of this, because if they aren't, God help us. I'm guessing that power management is such a low level issue that it's very difficult to fix with firmware if at all. That being the case, I'm not confident this phone will ever work properly and has most likely sounded the death knell for me for both Sony Ericsson and WinMo.
@bedlam_au
You may be right about power management.
That may be the answer.
Before my card corruption when I was entering SlideView
I always saw it REFRESHING media content,
like looking for it again and again....
have you tried it?
Code:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\Suspend]
"shc1:"=dword:00000000
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Power\State\Resuming]
"shc1:"=dword:00000000
We have been testing it with my friend for a while (since 24th of april) and he hasn't got any storage card problems after applying this *.reg. He had them every time before that.
@ultrashot: I think you've done it! Changed those keys and didn't even need to soft reset. I've been checking all day and haven't seen the storage card disappear once. Presumably it's going to stay that way.
Does someone feel like making up a cab for this? It'd make many people's day.
bedlam_au,

SD lagg???

I keep looking at other forums and am trying to figure out if the SD card in the problem why the phone freezes? Does anyone know anything about this... Agree or Disagree

I happen to agree, based on the evidence in the half-dozen more threads here discussing that same thing. It'll be pretty easy to determine if that's your issue...try running the phone without the card in it, and see if that makes a difference.
Now, technically, I believe the issue is related to the card, but may not be beacuse of the card itself....it seems like the phone chokes when there's a lot of files on the card and it has to index them. People who install apps to the card seem to experience this (or at least report it) more than people who don't, which would support that theory because installing apps to the card fills it up with files faster (per MB of space) than even moving a bunch of music might...and a large number of files to index could lead to this kind of behavior (theoretically) as opposed to just a card that was "full" by occupied volume. Again, you can test this by starting with an empty card, then filling it up gradually, and seeing if the issue appears at some point in the process.
In my opinion, the commonly-seen lagging issues in these phones may often (but not always) be casued by a combination of factors:
-class-2 card
-high file count on the card
-sense's (and maybe winmo's..?) constant re-indexing of card contents
Now, some people have reported that copying the card's contents to your desktop, reformatting the card, then copying the files back on to it resolves the issue for them. So, bottom line...who knows?
EDIT: here's maybe a better explanation (by example) of what I'm trying to say about the card being "full"...
Example 1: you have a handful of .mkv files ripped straight from bluray on your card, ~2GB each....putting 7 of those files on your (16GB) card would almost fill the available volume. But, since that's a small number of files, it wouldn't take the phone long to index them at all, despite the card being almost completely full. (again, my guess)
Example 2: you install a bunch of apps (say, 30-40), and almost all of them to the card. Even though those apps won't eat a whole lot of space on the card total (far less than 1GB probably), each one can have potentially dozens of individual files installed for it. In this case, the card wouldn't show as being very full (just from the apps anyway), but the large number of files would potentially cause any indexing of the card to slow down in proportion. (guess what...still just my guess) And, a lower-class card could contribute to the slowness in this case too...that bottleneck could multiply the effects.
It may help some people out to hide the program folders on the card from indexing, just to reduce the file count that has to be sorted through, but that's just an idle thought that just occured to me.

Thank you, I do understand what you mean by the amount of files on the card. By the way, are you havong freezing problems with your phone??

Actually, no...I've had absolutely zero issues with this phone, and I've had it (and used it constantly) for two weeks as of tonight. No freezing, no lag, nada. I don't keep a ton of stuff on my memory card (~15 mp3's, 4 .avi's, and 30-40 archived cabs, small handful of other junk), and I don't install any apps there (though I haven't bothered to remove the stock stuff put there by tmo).
I experience this lag, and altough i kinda agree with the card being the issue at the same time i am kind of hesitant. See the Card is a Class 2 which in theory will have a throughput of about 2mb a sec right? Mine peaks out at about 2.8mbps..... to me thats fast.... so i am not sure but i feel like the choke point is porbably in hardware. Again this is probably all bogus lol.
Like i said i do have this problem too, and i even reformatted my SD card and loaded all my files again. The problem still persist, and i really only notice it when i am listening to music via usb in my car. Also when i am scrolling through the pictures in my gallery(pics are in the SD).
Hope this makes atleast a bit of sense lol.
Disable Document Indexing by editing the registry or using a cab floating around the forums. Do a quick search and you should find it. This eliminates that lag no matter how many files on you SD card, with no degradation of performance opening files on the card that I can see.
nice man, thanks will have to look into that...
I have two HD2s (mine and my wife's). The experience with the two phones couldn't be more different. Mine has been perfect. My wife's has been very problematic. She has experienced slow, laggy performance, freezing that is only cured by pulling the battery, inability to unlock, text messages freezing for a minute plus, etc....... She isn't happy in the least that I convinced her to get rid of her blackberry.
On my wife's phone. I have tried a hard reset, various tweaks from these forums, switching in a 4GB class 6 card, removing the SD card completely and a few other things. Some helped a little but the phone just never worked right. It is currently being replaced by Tmo. With the troubleshooting I did I can't blame the SD card for the problems that phone had.
My phone on the other hand has been great and I have not had any problems with the SD card. I install all my games and non-essential apps to the SD card. I have ~650 MP3s on the card as well as ~900 various files that I take to and from work. There is a little over 8GB of data on the card with all these files. The only lag I have experienced is when switching to the HTC media player it takes a while (< 1 min) for it to index all my music and get to a usable state. I can try swapping in a 4 GB class 6 card to see if it makes a difference though since I have not had a problem I'm not sure I will notice a difference.

From wikipedia, here's info on the speeds of the different class-ratings for SD cards:
The following are the ratings of some currently available cards:
Class 2: 16 Mbit/s (2 MB/s)
Class 4: 32 Mbit/s (4 MB/s)
Class 6: 48 Mbit/s (6 MB/s)
Class 10: 80 Mbit/s (10 MB/s)

so, if your transfers are capping out at 2.8Mbps, that's just a hair more than 1/8th of the 2MBps that the card should be able to handle.

Will the phone work as normal after installing the cab?? I am knew to xda and winmo. Been on android os since it came out. I hate to ask but could someone post the link for that .cab file that fixes the lag
I saw that sirphunkee had posted in another thread that simply turning off your "recent documents" tab in sense should stop the indexing and therefore the lag as well. I had turned off the recent documents tab from almost the start of using the phone. I have not experienced the lag problem so this might be a testament to this working. I will turn it back on and see if things change for the worse throughout the day.
UPDATE: I have a had a little time to play with it during my lunch break. Everything seems to be fine with recent documents tab turned on. The slider seems a little slugish in now, like there is a second of lag before it moves. It doesn't happen all the time and I may not notice if I wasn't looking for it. I can brows just fine in the file explorer, texting isn't a problem other than the clunky interface, all is well so far.
Also of note is that I am running the stock ROM with co0kie's home tab and a slew of other visual mods (mostly transparencies). I also made quite a few changes to memory allocation via registry edits. This might be the difference and worth trying. I made many of the changes noted in this thread, basically all of them after "Suitable for all ROMs" and before "Added 11/2/10". I wish I would have thought about this earlier.

Memory card erased

That was too bad experience for me. I noticed today that the apps I moved to sd card, wouldn't respond and they also disappeared from the programs list but they were listed in remove programs list. So, I went a step further and looked at the contents of my sd card just to discover that everything was lost and returned to factory default folder configuration. All my photos, music, etc. are gone. The card isn't dead but only erased. It still has some folders but I assume they are the default data folder that were created when the programs are accessed.
Now, I removed the battery today without shutting down first. Could that have caused the problem?
Any way to recover my data back?
You could try to recover them the the program "Recuva " its very good freeware. I'm pretty sure its windows only, best of luck.

I am currently running active file recovery and had no luck with quick scan. I am now running thorough scan but I don't think it will help.
nope, only folder structure discovered but empty. Too bad but it shouldn't be like that. Some corrupt files would be acceptable, but thw whole card????
As andy suggests I would try recuva anyway you've nothing too lose and it may work even where the other didn't.
Hmm, happened to me once on a crap sd card.. Had to reformat and suddenly the read/write speed drop drastically, around 150Kb/sec on class 4 card.. Luckily, i happened to keep my old class 2 sd, works like charm.. I think it had to do with the conditions of the sd card..
what did u do to yr card that made it happen that way?
like what the others said, try running it thru recuve to recover the files then run a scandisk on the card
As said, I removed the battery without shutdown or dismount. I believe that's what has caused the problem.

I don't think that's what caused the problem as i removed the battery a few times without shutting down and never faced this issue.
One time i got an error message and i could not access the files on the microsd. The solution was to run a checkdisk and fix any bad sectors.
I always backup my microsd at least once a week for a rainy day, i strongly suggest you do the same from now on.

+1, I have Titanium Backup, run a full backup (User apps + Data) every night and backup the card (using Simple backup on Ubunutu) as often as I remember then if i lose or damage my phone I can feasibly recover everything.
I was getting message from PC when I plugged my phone on USB from day 1. The message was that the card need to be scanned for errors and so I did that all the time. Last time I plugged my PC to cradle I got the same and the scan fixed some errors. If the battery removal didn't cause the problem then it should be that last scan. Maybe my card was faulty but not completely. It's the stock card.
Many users reported that their card died while they were using their DHD (most of them if not all got a Samsung microsd in bundle).
I use a SanDisk class 2 that i have for two years as it's more reliable and transfer speeds are higher than Samsung.

I know this but mine hasn't died. It has been doing this from the first day. It's working though. Can't tell for sure what has caused it to be erased but it was done in seconds.
Fortunately my photos were synced on the PC and so I recovered them from there.

oh this.
its likely caused due to when u mount yr sd card to yr pc and fail unmount it properly from the pc b4 disconnecting it.
Try photorec - if the data is physically still on the card, it will find it. No fancy interface but imo the best file recovery program out there

Solved: Android System eating battery

So, I've seen quite a few posts now about Android System eating way more battery than it should, and I'd noticed the same thing on my phone since day 1. I tried turning features and settings on and off, disabling apps etc etc all to no avail, but I've finally cracked it
Format your external SD card via the phone settings, and use Kies to re-sync your content. Mine was originally formatted as FAT32 and I'd dragged and dropped the music and photos onto it via my computer. I don't quite understand the mechanism responsible, but this seems to be the source of my phone's unusual battery drain. Android System battery utilisation has dropped markedly, and battery life is greatly extended. I noticed the media scanner working for a few hours after I initially inserted the SD card, however after formatting and reloading via Kies the media scanner didn't run, yet all the content shows up where it should. I can only guess that some process responsible for indexing the media was running amok? Either way it's now able to sit in flight mode overnight without dropping a single %, whereas previously it'd drop at least 6%. In active use the display now always sits at the top of the battery use table rather than Android System, usually by a large margin :victory:

Either way it's now able to sit in flight mode overnight without dropping a single %, whereas previously it'd drop at least 6%. In active use the display now always sits at the top of the battery use table rather than Android System, usually by a large margin :victory:

What if we don't have an external SD card?

Then this isn't what's causing your issue.

So, I've seen quite a few posts now about Android System eating way more battery than it should, and I'd noticed the same thing on my phone since day 1. I tried turning features and settings on and off, disabling apps etc etc all to no avail, but I've finally cracked it
Format your external SD card via the phone settings, and use Kies to re-sync your content. Mine was originally formatted as FAT32 and I'd dragged and dropped the music and photos onto it via my computer. I don't quite understand the mechanism responsible, but this seems to be the source of my phone's unusual battery drain. Android System battery utilisation has dropped markedly, and battery life is greatly extended.

So what should we format the memory card to? Fat32 still?

Just let the phone format it, there are no options for which file system you would like.

Much, much better. Oddly the Gallery app now shows more album artwork that was always located on the external SD card, but obviously was not being properly indexed. So far today I've got 3.5 hours of screen-on time and still have 58% battery capacity. Previously it'd have been that low with no screen time.

Couple more questions thn I'll stop annoying you :silly:
1. What's your Android System vs Screen now in terms of usage of the battery (% wise). And how was it before you did this little trick?
2. How should I go about putting everything back onto my SD Card (backups, pics. apps, etc.)? I've never used Kies before so I have no idea what to do lol.
3. All you did was go to settings, then storage and hit format sd card, correct?

You're not annoying me, honest, that's why I shared my results here ;P
1: Android System is currently 13%, screen is 29%. Previously Android System would be over 30% no matter what and often much higher if I didn't use the phone much that day.
2: Copy everything off your SD card onto your computer using whichever method you currently use. In Kies there's a file browser icon that lets you browse the contents of your phone, as well as copy things to and from it. You don't have to use the automated sync tools in Kies, you can simply drag and drop using the Kies browser.
3: Yup, that is correct. Not sure if it's maybe formatted using exFAT now, but I believe that's Android's preferred format these days.
I think I formatted my new SD card when I put it in the phone but not sure.
Is there any way to check and see what the card is formatted to? exFAT? Fat32? It was a brand new Samsung card.
I'm not really seeing bad battery life at all just curious.

Yup, you can put everything back on to the external SD card via Kies.
Maybe it is also caused by kitkat bug, which is Not only triggered by skype, but also hangouts etc etc http://www.zdnet.com/kitkat-giving-...-says-google-as-it-prepares-a-fix-7000027051/

i'm also getting massive android system use for seemingly no good reason, and it started like 4 days ago, my phone was fine before that.
I'm new to android so I don't even know where to start with regards to uncovering problems of this nature

Even dumber, you didn't read the article ? It is indeed related to battery drain and is a common bug in kitkat

[HELP] media.extractor battery drain

I have an issue about the battery. I left my phone in my bag while working, after 7 hours, my phone died. I thought it was broken or something. But when I tried charge my phone I founf out that ran out of juice. It's just weird because I left my pphone in the bag with 63% left. It's not like this before.
Here are some information about my phone
- Stock rom
- I already updated the May patch
- Not rooted or anything
And oh, when I went to the battery section. This showed up (attached image), media.extractor draining about 40% of my juice. Anyone else encountered this? Let me know if you got some remedy for it. Thank you guys!
I was reading forums and it can be caused by some corrupted file on SD card, because looks like this app scans media files. Try removing your SD card (if you have one). If that doesnt help, try moving all your media files to your PC. Then look if drain continues.

I browsed some forums and all of them said that it is some corrupted file on your storage.
