    Default Having a battery drain problem on LG G3?

    I had performed a Factory Data Reset more than a few times with no success. In my case the battery continued to drain while the top potion of the phone continued to overheat; I assumed that to be the processor in overdrive, but what was causing it? I downloaded GSAM Battery Monitor and noticed SYSTEM (SD) was over 50% in usage by itself. I swapped out the 128 GB SD card with a lesser 64 GB SD card. Now the phone is back to being as cool as a cucumber with normal battery drain. I had the phone operating normally for about 3 weeks before this and even after installing the 128 GB card the phone operated great, so I suppose it must be something recently installed onto the card, or the card itself that was doing it.
    One thing for sure, the GSAM battery app tracked down the problem quickly.

    This.

    SD Cards are just NOT reliable. You'd think that after all these years manufacturers would come up with a way to keep these things running, but more often than not, they're just like the old floppies. Eventually, they'll die on you.

    Now you see why manufacturers are moving away from SD cards hehe. A bit unreliable, I don't know why. I once had a corrupted SD card on my Note 2 and it drained the battery like crazy, since the system keeps trying and trying to do the Media Scan.

    No such issue on my S4 with 128gb card. As far as sd cards, Google does not like them since they want you on their data mining, revenue drawing cloud.

    That said, more are offering cards now and apparently sd cards are implemented better in L's framework. Card writes apparently back as well.

    I have you since formatted the card and tried to use it again?

    Samsung, especially, has a really bad history with SD Cards. Mine didn't start failing right away, it took a while. And it happened on the Note 2, the Note 3, the S3 (a friend's, not mine) and an S4. All different SD Cards, all different brands (SanDisk even had a full year replacing SD cards if you only said you had a newer Samsung device in 2012), all fried.

    I will continue to investigate the cause, formatting the card, etc as soon as I have the time to make sure all of the vital data is exported to my laptop.

    The OP's description is really a bug in Android, that should have been fixed a long time ago.

    Android periodically scans memory (internal and external) look for new files that need to be incorporated into the Gallery. If it encounters a corrupt file or directory, it will sit there and churn forever trying to read it. That's what eats the battery. Every other OS on the planet is written to stop trying to read after a certain number of failures, but not Android.

    There are apps in the Play store that will prevent this. Some, maybe all, require root:

    https://play.google.com/store/search...20media%20scan

    Reformatting the SD card will map out any bad sectors and probably fix the problem, too, but if the card is failing it could happen again.

    Are these problems usually caused by placing apps/app data on the sd card?

    What percentage use would be normal for the System? Mine reads around 9 %.

    I have a 64GB SD Card already and I'm on my second G3. I checked my System Usage and it was 20% with a wakelock. Nevertheless, i have re-formated my external SD Card. So ill report back how it goes.

    Usually? No. Possibly, if the app data includes media files. That's all the scanner reads for purposes of indexing and building thumbnails.

    I reformatted the 128GB but I'm afraid to try to re-install it. My G3 has been on 100% for about 4 hours now unplugged with the 64GB SD, mostly on standby except for the few things I check on, but still I don't remember it ever lasting this long at 100%. I have Battery Doctor and GSAM Battery Monitor installed. The face of the phone as well as the rear buttons are absolutely cool to the touch. Sorry guys but unless I get more problems I'm not messing with it.
    EDIT: Make that about 5 hours at 100%.
    Other things I've done for these results:
    Once the G3 is operating with less battery drain (from swapped out SD card) I Use LG Backup service and back up on the SD card.
    Next I Factory reset
    Next restore using LG Backup file on the SD card.
    I'm using a Sandisk Ultra 64GB with a 10C rating
    I did all of this around 12:30pm
    Finally shows 99% after 6:PM

    I wished companies started incorporating bigger memory sizes into their devices. If they had a G3 with 64/128GB variant then there's no need for SD card slot.

    SD Card storage is slower and less secure than Internal storage.

    Default Re: My LG G3 Battery Drain Cure!

    Hello all, I have not been here for a while simply because life always has something to deal with. I saw this post and wanted to share my findings. I bought the G3 a little over 2 weeks ago and from the beginning I quickly deleted what I could and disabled what I wanted to delete but since carriers like to take up space on phones we buy, we have to root in order to remove that junk, however I did not want to do that until I was sure I wanted to keep the phone.

    The phone is top of the line compared to SG5 and M8 and I noticed I was getting 150+ hours on the very first charge and it got better. Once the 14 day period was over I quickly rooted my G3 using towel root, no issues there.

    I must say that prior to this I did NOT use any google services as I do NOT trust them.
    Once I was rooted I started to debloat all the crap at&t adds to MY phone and installed things like xprivacy and appops xposed modules to better control things.

    Once all the stuff I needed to feel safe where in place I enabled google play store and you tube.
    After downloading a few apps from the store I charged my phone up.
    Over night the battery drained so much it was ridiculous and I was on the hunt for the problem.

    After using some helpful apps like greenify and others I still had the battery drain problem.

    Here's the answer to it all, now I bought a 128gb card for $14.50 shipped. That was cool.
    The sd card is not the problem here and everyone who is factory resetting and reformatting their cards are wasting their time.

    The REAL problem is google play store and mostly "google services".
    So I disabled google services and quickly noticed a difference. I will update this with further testing but as of now my battery is already better without google sucking the life out of it.

    Download receiverstop from Defim and see just how many it has and you will know why google restarts itself all the time after you force stop it.

    Using receiverstop will not help though but simply disabling the google service will do the trick, when you need to use the play store just enable the google service again and disable after you are done.

    Hope this helps as I notice its helped in just a matter of hours.

    I guess it depends on how you define reliable. I think I've only had one fail in the entire time I've used them in cameras and phones. Probably at least 6 or 8 years. (yes, that includes regular SD cards as well as micro SD).

    After re-formating my SD Card yesterday, I charged it up over night and took it off the charger at 6am when I went to work. I used the phone "normal" today. "Normal" for me is basically not being on the phone constantly like we normally are when we first get a device. I used the phone to send texts, make a few calls to my kids, check the web, FB, Hangouts and G+.

    My G3 stayed was still at 100% 2 maybe 2 1/2 hours after I took it off the charger and checked some of the social media apps. When I got off work at 5PM I had 62% battery remaining, which is quite good imo.

    However I found that when actually using the phone for long periods of time, it does drain rather quickly...maybe because of the screen..idk. I say because after I got home from work, I used the phone a lot more than I did at work and I was at 37% in a matter of 2 hours. Which consisted of checking emails and replying back to them.

    But for the most part, I'm content now seeing that the battery works good for my everyday use.

    My (lg g3) battery drains so massively I don't know why but I think my phone came defected. When I first got it when it came out a day after I charged it played with it fine after a week I started noticing that my battery would die so fast I was like wait a minute I charged my phone from night to mid day when I woke up at lunch time it whent from fully 100% to 35% in a matter of 3 and half hours of me hand using it. Then when I played games or I would go on tumblr, my phone would overheat so badly. I literally just burned my finger when I touched the volume button. That's how hot it was. I was going to go return it the next day. But I was too lazy to do it. I don't know if can change my phone now I already scratched the phone and their noticeable only on the sides though I have a screen protector their not big but they are viewable. So I'm stuck with this stupid broken phone for awhile ugh. Sigh.

    That's kind of the way my phone was.
    It was fine during the first two weeks, then it just started having battery drain issues and overheating.
    Hopefully an update will fix these issues.
    For now anyone with overheating, lags and battery issues should keep posting.
    Maybe they will see all these reviews and do something about it.
