64gb micro sd draining battery? - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey has anyone noticed their memory card draining their battery. When I pull the memory card and check the battery stats the phone seems to sleep twice as well with the memory card in it. I can unplug my phone leave it for 5 hours and be at 90% with no memory card if I try the same with the memory card in it ill end up at 75%

I have a 64gb card -- no noticeable extra drain. Actually I'm on day 2 without a charge, about 45 minutes screen time, and still at 60%.

I actually do, I'm using a note 3 and i didn't have this problem before. I had a water damage and after drying, changing the charging port everything is working fine except my battery would die within hours; even if i Do Not use the phone it would drain within 6-8 hours. I just tried it without the sd card today and so far in 4 hours i have 80+ % and i have over an hour of screen time. Im not sure what the causes this problem, i'm thinking of cleaning the motherboard with 99% Isopropyl Alcohol Antispetic Solution to make sure the is no power leakage.

No... memory card does not cause battery drain, brightness setting needs to be lowered to compensate excessive battery drain. Mine is very low. As far as the phone beung dropped in water, replace the battery before overthinking on cleaning the board..etc..etc...etc

Anyone with Battery drain problem?

Anyone having any battery drain issues at all? My wizard only lasts 12 hours till it dies on me. Even if it's on standby for the whole 12 hours.
This is obviously abnormal. I want to see how many of you in here have this problem, or if it's just me. I have replace a new wizard (from the same store), and this problem still persists..and i have also tried using a new battery with the same result.
I recently came across this program on this forum:
http://forum.xda-developers.com/viewtopic.php?t=45168&start=25
B_uptime which records your usage time. The you are using your phone the processing time will be incremented, when you have it on stanby the idle time will be incremented. But with my phone no matter if am using it or if it's on standby, only the processing time is incremented.
I am suspecting this is the cause for the battery drain. Can people with or without this problem try this out please? And see if the idle time increment when you put the phone on standby?
Hoping to get some feedbacks. Thank you so much!
See this big thread here with people who have similar problems. http://forum.xda-developers.com/viewtopic.php?t=45601
I personally have my battery standby set at 2 mins.
jpflaw00 posted an interesting observation in the b_uptime thread too:

Try to remove the memory card and see if the phone still refuses to "idle".
I am making a new topic, to get a survey on howmany ppl are having this problem and if they have their's fixed.
I have tried pulling out the SD card, but the idle time still won't count, and this is my 2nd wizard.....so I am pretty screwed....I just don't know why....
ppl please post your comments and fix thx
ok, I have just tried pulling the SD card out, and it KINDA works! It only works when I take the card out, and let it turn itself off after 1 minute. If I manually press the power button, and then turn it back on again, the idel time still will not increment.
Did you just let it go on standby or did you also tried pressing the power button? So I guess the problem is not fixed for me.
I am using a Kingcap 1gb Mini SD, what about you guys?
How about people with battery issues state the brand, size, etc. of memory card if used. Otherwise people should state if they have a battery problem even if they don't use a memory card. Let's narrow it down to see if the issue really is the card :!:
jpflaw00, so does the counter still work for you if you press push the power button, and then turning it back on after 1 minute?
Want to know if I am the only one having this problem.
I had the mem card out since yesterday @ 3, fullly charged, and I didn't press the power button, letting it turn itself off, after almost 24 hours, it's @ 50%, so very good....but very inconvenient......and I do want to press the power button.
OK, I confirm, my phone finally works with the SD card out.
When the SD card is in, the idel counter stops working.
So we have narrowed the problem down to being some kinda of problem with some brand of SD card, OR simply the SD Card Slot.
I am using a Kingston 1gb. Really want to try a Sandisk and see the result.
Well this will blow your mind.... i DONT have a Memory Card, and yet my Vario battery lasts 1 day tops without charge. No WiFi, no GPRS, no BT, no IrDA, no Crazy Today Plugins.
gazzrenn, you have a more serious problem than me.....did you try hard resettting it and not install anything? and what rom are you on?
OK, I CONFIRM, THE PROBLEM IS NOT THE SD CARD! It is a problem with the SD CARD SLOT! I tried putting in a blank card (The piece of plastic that came with the phone), and the counter stops working, so there must be something wrong with the sd card slot..when something is inserted it keeps the phone running...
omg..anyone having this problem?
Hey jpflaw00, any news on your Wizard?
Does your battery still drain? Have you tried putting in the Plastic thingee in the slot and see if it still drains?
Thx/
well as far as i can tell no...i haven't really noticed anything...to me it seems as if the battery is fine, but i haven't really been testing it out...i think i have better battery life now, but i'm not too sure...i recently upgraded my rom, but maybe the problem has to do with phonealarm or something that keeps transmitting info back and from the memory card...but if you are having battery problems without a memory card, then i suggest trying the new roms out to see if this fixes any issues you are having...my suggestion is the mobiz edition i am using right now...if i'm right i'm getting better battery life, but then again i could be wrong...just try it out...anyways i will charge my phone as soon as this cycle is done...then i will examine the phone battery stats, and then i'll get back to ya...good luck!

My personal battery killer is..

the micro SD card!
i checked it twice overnight and during the day.. so i can say that for sure!
I own a Samsung micro SD 8gb class 6..
Night 1: lost 35 % in 7 hours with SD in it, constant data connection with hourly updates
Day 1: lost about 54 % in 8 with SD in it, constant data con. , hourly updates, some calls,texts & browsing in Opera
Night 2: same conditions as night 1 but without SD card.. lost 7 %
Day 2: nearly same conditions as day 1 but without SD card.. lost 27 %
Now a question: are sandisk cards better? i really need a new 1 cause my samsung's ****ed up!
Hope i could help someone with this..
Use BsB Tweaker which can enable power saver for SD Card.
And keep in mind that Battery lose first half capacity very fast and then stay on long time on the level 30-40-50.

In my case it's the exact opposite, power loss from 100%-50% is slow, below 50% it can go empty within 7 hours in STANDBY (reproducible). Thanks for the advice with BsB Tweaker.
PS: I have a sandisk 16gb class 2.
you mean the power saving option? it's enanled since the first day..
i know that with the first half but the sd card is really killing me! currently working outside so im in need of the radio.. with sd card in it and running fm radio, battery drainage is about 19 % per hour.. thats not even a bad joke anymore, its realy frustrating!
thank god that i have electricity here
That can't be right. Must be a rogue application. I have a 16 GB card and the phone never loses more than 1-2% (radio off) during the night.
must be my samsung card.. apps are all closed over night!
i got tomtom,navigon,some music & games on my card.. no idea
Formaty sd card and try again.
Must be some application installed on sd or some problem with the sd card itself
Ill try it when im at home!
is there an alternative for the built in fm radio? tried listening without sd.. same result 3 % loss in 10 mins! how can a dumb radio use so much battery?
i remember listening radio with my nokia e90.. listend for hours with minimal battery loss
It makes sense to me, thats why I was saying this here http://forum.xda-developers.com/showpost.php?p=5230146&postcount=10
Any fellows here are using the A-data class 6 16gb and dose not affect the battery life? I'd like to ask this again.
Thanks in advance.

I tried mine too, and I lost 4% in 10 minutes, but that was with the screen on. I then turned off the radio and lost 3% in 10 minutes with the screen on, but not doing anything (other than usual-for-my-phone background tasks). I then turned the radio back on and turned the screen off, and it used less than 1% in 10 minutes (I say less than 1% because the indicator had not changed.)
To me, that says that (in my case) the battery killer is the screen, which I can accept because I have it lit very high (I just don't like it dim.)

The only major thing I'm considering changing, to see if it has any effect, is my windows live config. I currently have my sync frequency set to "as soon as it arrives", which requires a constant data connection (before that starts a flame war, please read this.) I'm gonna turn that off and see if it improves, but I still think the screen is my big problem.

Sounds like you need to recalibrate the "remaining-charge-estimate-circuit-thingy" in your HD2's battery. Drain battery to as near as nothing as possible and fully charge it without unplugging it (I have heard its suggested to do this with the device off). Might work straight off the first time, might take a couple goes.
Do not leave the device below 20% charge for any long period of time as it can cause problems with the Li-Ion battery.

I'm gonna try it on mine and see if I have any improvement anyway. I'm sure we have different things running on our devices. I'm just trying to narrow things down before removing the SD card to see if that does anything.
SD Card is one of the factor
To my sense, if a lot of softwares in installed in your SD Card, then definitely the battery will deplete rapidly.
I install all 3G-constant-data-softwares in the system memory, not card. Those not required CONSTANT 3G data connection and not to be running 24/7 will be installed in SD card (eg. 1-Calc, TCPMP, Lexisgoo, Resco Explorer).
So far, with the stock ROM and related softwares (installed at "right" locations) gives me average 1 full day battery juice having 25% balance. And again, battery consumption is a very very subjective topic. SD card IS definitely one of the battery earter.
I have not tested the following in a very detailed way but I think it worth while trying it:
Even so I have used the power saving tweak from BsB Tweak I found in sk Tools in tuneup that all Power Saving features are switched off.
So I switched On all Power saving features in sk Tools and I have the feeling that the battery usage is less now.
For example:
From midnight full 100% charge till 8am in the morning I had 89% left which is a little bit more than 1% loss per hour and this is not bad.
But with the new Radio 2.06 I have the feeling that battery power is getting more drained during a talk or during interent connection.
On the other side the reception is quite good and I have also the feeling that data connection is better - receiving data faster after a connection is established.
Again: This are all "soft" fatcs I have not done a sientific evaluation
I have a San Disk 16GByte Class 6 storage card.

Hi, are you sure that your micro sd is a sandisk class 6? cuz I've never found Sandisk has released a class 6 16GB microcard..thats why I had to buy the A-data one.
The only software I have installed in the storge card is a GPS software IGO8.
This battery issue is driving me crazy, I begin to miss my HTC HD(original 1.43 ROM) which drops only 2%(My hd2 loses about 40% power) every night, even I always have kept my data connection on.

CONFIRMED: T-Mobile USA HD2 MicroSD is Faulty!

We've uncovered that the 16gb microsdhc card that comes with the T-Mobile USA HD2 is faulty in 2 ways.
1. When the card is used battery life is AWFUL
2. Files are "deleted" but space is not freed.
For example: I have 10.5gb free on the card now. I delete a 2gb file from the card. After deleting I still have 10.5gb free.
Can someone test this a little more for us? Do other cards have the same effects?
Thread this was discovered in: http://forum.xda-developers.com/showthread.php?t=653229
My SD from T-Mobile completely died after 5 days, they're sending me a new one in the mail...it won't recognize on a PC or in a phone at all, lost all of my docs/pics/music/etc...
Remember boys and girls, back up your data!
Oddly enough.. I don't have these issues. My battery drains roughly 1% per hour on standby (a little less actually). I unplugged mine this morning at 8am, and had a day of heavy usage (15 mins talk time, 3 hours browsing, 20 mind of fpsece, 1 hour of music, and 30 mins of video), and I am at 34% as of writing (8:35PM). That's not bad for 12 and a half hours.
Also, when I delete items from my SD card, my remaining space reflects the changes I've made. I have had 0 issues with the card.

I have a feeling that there was a faulty batch.
I had bad battery life with another 16gb sd card that was mine. It's not the sd card that's faulty but the sd socket itself or the drivers. Hopefully it's the drivers. Or something about Sense polling the sd card.
I have bad battery life with an italian hd2 and 16gb SD. I don't think it is something from t-mobile.
I put the 16gb card I was using with my Touch Pro2 in the Tmobile HD2 and it wouldn't even recognize it. I think it even corrupted it because my laptop takes forever to access it.... I will try the 4 gig I have and post if anything changes.
I purchased my HD2 on launch day and so far haven't had an issue with it. I have had issues trying to sync my Win7 64-bit PC and the phone with Active Sync but so far no issues with the card itself. It's like a portable Harddrive to me. I have VLC player installed on my work computers and put XVid's onto the phone and run them off the phone at work without issue.
I'll look further into the space issues with the deleting large files, but I've moved lots of vids on and off and never noticed anything.

Is this for the Tmobile USA HD2? I have terrible battery life on mine and honestly its annoying and frustrating knowing I cant even browse the Web for 15min knowing my battery will drop 10-15%. I have blu-tooth off, and screen brightness at 30% and battery life is still horrible. This has worse battery life than my Sprint Touch Pro 2. This phone reminds me of the horrible battery life of the Sprint Touch. I dont know how you get those amazing numbers.
By the way, I dont have the weather or email autochecking. Everything is set to manual. I send about 30-50 quick texts a day.
really? i can use my phone on the internet for half an hour with the battery dropping oonly ~5%.
this is on wifi.
have you tried a couple discharge/ charge cycles?

I think this is a batch specific problem. I've done discharge and charge cycles and my battery goes down about 8% an hour on standby.
Also, the sd card will not get rid of things deleted off of it. they are gone, but no space is freed.
I'm going to go in to my t-mobile store and try to get a replacement.
Sandisk 16GB cards have problems!
I think Sandisk has been having MAJOR problems with their 16GB MicroSD cards for a while. I had one in my Touch HD and I needed to reformat it about every 6-8 weeks. Major pain. The last time it would not reformat again and after a major effort, Sandisk agreed to replace it (had to send in old one at my cost).
I am convinced they sent me the old one back because it is pretty much DOA!!! If it is not the old one then this one is buggered up too. It worked for a couple of weeks then stopped being seen by my HD. I tried to format it from 3 different PC's and two different (compatible) readers with no luck. I gave up and bought an A-Data 16GB card with no trouble at all!! Over 6 months later and not a single hiccup with that card. Keep in mind that I pretty much just leave the card in so "wear and tear" is non-existent.
My suggestion? Dump it and get a different brand (card that is).
Gordo
PS. Just do a Google search and you will find MANY people having issues with it.
mine works fine so far keep us posted....i deleted alot and i got my mem back

Yes, this is for the TMOUS HD2. What I did:
1. Bought the phone
2. Let the battery die once
3. Full charge, and let the battery die again
4. One more full charge, and then normal usage..
I know battery conditioning isn't exactly needed at this point, but i did it anyway. My email is pushed every 15 minutes, and WIFI is on about 60% of the time. No blutooth, and my weather and facebook are set to manual updates. Stocks are diabled as well.
Obviously BSB tweaks is installed with power management, and automatic screen dimming is on as well. I really didn't do anything out of the ordinary.
My SD card also works outside of the phone, and in my G1 as well..
I have the HD 2-NOT from tmo-and haven't had any issues with my 16 gig sandisk card-ever. And my battery life is really good. Best of about any PDA I've ever had.

Thanks bro. I will do what you did on letting the battery die and charging it full again. Now, isnt it bad to let the battery die fully on li-ion batteries? Im a little worried on this but will still do it. Thanks again.
You can buy another 16GB microSD and copy all data, and leave the original card secured.
Dane-Elec (class 2) is relatively cheap, and it's made by Toshiba (same as Kingston class 2 16GB).
Though it's a bit slow, it appears to be reliable.

sandisk is super slow... :/ I'm formatting mine. it gives me my space back now, but the damage has been done. only 5gb free with like nothing on it.
I just formatted the card and didn't put my backup back on. I'll report on battery life compared to what I had today.
Should the two posts be merged (or one close) to keep the issue on the same thread?
Couple of points to consider:
1) Having a memory card in a device will always drain it faster. In my netbook, if i leave an SD card in, I drain the battery faster than with out it. And I'm not even accessing the card, its just in.
2) There's a "FilesToBeDeleted" folder on the SD card. I don't know much about the file structure but is that like a virtual recycle bin?
Besides the first day of getting my phone and charging it that day, I've only done two full charge cycles (besides plugging it in to flash a new rom). I've had it off the charger for 9 hours and I lost 66% so far. My battery drain has lessen quite dramatically after I did some tweaks. I plan to reformat my memory card to night to clean it up and move some apps from my memory card to the phone so that its not perpetually hitting the card.

MicroSD preventing idle

MicroSD: Genuine Sandisk 32GB card from a reputable retailer.
ROM: Stock 1.72.831.1 Hong Kong.
I loaded all my music and some games onto the card and found that using Battery Log which I found on here that my phone was going from 100% > 87% overnight with everything off which translates to 16ma idle with Battery Log. With the card on the table overnight that the phone went from 100% > 97% or the same numbers when I put in a 2GB and 16GB cards that I have lying around. I've had the phone for 6 months and these are my consistent figures. With these cards inserted, Battery Log registers approximately 4ma consumption at idle.
I then formatted the 32GB Sandisk card using windows 7 (I'd been using the phone's utility until now) and did a full format at FAT32 with default cluster allocation as a last resort and left it empty without any files whatsoever. Well, Battery Log is still reporting the same 16ma consumption at idle and I'm out of options here so I've come to the masters here at XDA for their thoughts.
I never get any errors from the card, have filled it. The only unusual behaviour is from the idle.

I want to solve a technical problem for myself and other users about correct idling and memory card problems not just get by on a charger.
My phone used to give me 2 days moderate usage on a single change. With your solution I would get 2 days on standby with zero usage. Or that's 40% drain over 24 hours instead of the previous 10% drain while idling - big difference and reason I want to get to the bottom of it.

I don't see it as a problem, it's a known fact that the phone uses more charge when the SD card is in use.

Your post states the phone goes into idle, with a higher mA consumption. So it is idling, it's just drawing more current, maybe it's a design flaw of that certain class/size of SanDisk card?

Something is causing my S4 CPU to be running 24/7 and killing battery

For the past few days I've noticed my S4 randomly go from 80% battery to completely dead while just in my pocket... when I take the phone out, I notice that it is running very hot. I also keep getting notifications that my memory is completely full (I have 16gb + 32gb sd card).
This is a screenshot of what is causing the cpu to be running. 'Media' caused 80% of my battery to be depleted. Also, the battery decline seems to be a steady slope.
Is there any way to figure out what is causing this and how to stop it? Thanks!

Install wakelock detector. Charge to 100% and let it drain. Then check wakelock detector PRIOR to re-charging. THis will tell you exactly what is keeping the unit from hibernating properly. Poor case design can cause overheating as well. My i377m gets quite warm charging with the case on, so I just take it off. BetterBatteryStats also works.
