Hello!
Please allow me to introduce myself - I am a long-time xda forum lurker, who has not had the chance to post due to the fact that I am neither an expert, nor have had any questions that weren't covered by a simple search.
However, the day before an interesting thing happened to my P880. Without updating the software, due to the fact that my operator does not support it, battery life suddenly plunged significantly. In fact currently when charging, it discharges faster than it charges. So the only way to use it is to turn it off, charge it and then use it for a couple of hours.
As I said my software is stock and I haven't changed it for almost a year since I got the phone. It's version is "LG-P880-V10h-NOV-19-2012" with 2.6.39.4 Kernel.
That is what makes this issue even more interesting in my opinion, I cannot find a cause for it.
I note that the phone is warm to touch, so something is wake-locking it. However I am not an expert, but I will do my best to provide additional information if I can.
Thank you very much!

First of all download BBS and see what is keeping your phone awake. If you say that the phone is always warm than that wakelock seems as logical culprit. Something is keeping your phone stuck on high frequency and keeping it from deep sleep. Use BBS, you will know more after that..

The awake time is 9%, similar to what it was before, however the prone has been woken 872 times by System(radio). At the moment the phone lasts for 3 hours at most, while being charged at the same time.
Check your radio settings,maybe it is connecting to network all the time. Also you can freeze it..

Thank you for your quick response,
I force stopped the radio from the applications, and I had tried that before as well, however there is no noticeable difference, I can still see % drop by the minute.
Maybe it is battery malfunction..
Can you provide a dump from BBS?

radio isn't fm radio. it's needed for signal, dont freeze it
Issue is resolved by removing the external microSD card.
Now that was unexpected...
I haven't tested it with another SD card if the problem was in the card or in the phone itself.

is there any songs/videos in the SD card? i think the problem is with android's mediascannerservice. happened a lot. try checking the micro sd card for errors using windows.

It can't open the micro sd card from Windows. It simply isn't there.
Yes there were videos on it.

well, there's your problem. it was the mediascannerservice on android. the thing that scans the storage for media files for your music player, video player etc. it will go insane when your memory card is corrupted or damaged, which looks like what has happened to your memory card.

HI
My wife has my old Touch Diamond2. She complains that after charging it overnight, the battery shows as FULL, but within a few hours it is dsicharged.
1. Does the battery need replacing
2. How can I check to confirm it is the battery and not the charger/phone.
regards
Max

Thanks Senax for the nice link.. That is very nice thread to read and understand
thanks
I think the phone possibly has a hardware fault.
It strange, because if I take the simm out the phone keeps alomost full charge for the whole day!!
Not sure if its worth fixing.

May be you can check what all kind of networks are working/used when SIM is in? Also make the network selection Manual instead of AUTO and see the difference.
thanks.

I had the same problem...
recently I did two changes...
I Flashed the last radio
I Flashed the last Photon UX Room.
And then I fixed the battery problem...
why? I don´t know
lfallasm...
Thanks lfallasm and TD2IN
I dont want to flash the phone cos I have software (TomTOm) on the phone for which I no longer have the original CD to re-install. Also I have never flashed before.
I will try the network selection suggestion.
cheers
Network selection is already set to Manual.
I noticed something very STRANGE today.
I thought it maybe due to the signal in the new house we moved to, so I took the phone to work. Made one call and it went dead. Tried to start the phone, but battery to weak.
I took the sim out. started the phone without the sim and HEY PRESTO, battery is 75% full!!
Any ideas whats going on??
You should really flash it first, and if it fails you have a faulty phone. But flash it with HTC stock Rom, because you will lose waranty if you use anything else.
Its out of warranty. (My wife uses this phone now)
Would a FACTORY reset achieve the same as flashing with a HTC stock rom??
regards
FIXED.
The battery was faulty.
Apparently is had developed a slight "buldge" in the middle. Probably due to over heating.
Bought a new battery and all seems well.
£8 battery saved me buying a wildfire S for the wife.
Hi all,
I brought a memory card of 8gb after putting it in my phone my phone started heating up even when browsing.Is this normal?
Yes heating is normal.
However I 've never heard of it associated with a memory card. It usually happen when playing HD.games or using wrong charger. Or even with original charge but doing works while charging. In short, heating is normal.
well there's a range for "normal heating" it may not be writen [well I don't know haven't read the manual ] but if the heat goes to a point where you can't handle the phone, then that's no normal thing

When your phone gets heated up to the point where there's a problem, it will let you know with a warning message. Happened to me once had the phone as gps on my car with 35 degrees outside and the sun was hitting it. Gave me a warning temp is too high. So yea.

Thanks man!!
Sometimes it heats up when you do multiple things simultaneously. It happened to me while having a comic book reader, Yahoo Messenger, Skype, Youtube and the browser open for more than 10 minutes. But only once, and it cooled down instantaneously after 10 minutes or so, without me having to close any of those apps.
Try monitoring whatever it is you're doing when it's heating. If you're multitasking vary the open processes you have open by killing them one by one until the heating problem goes away and you can locate the app/process that's causing the problem.
Another thing: try replacing the card. Is it a MicroSD or a MicroSDHC ? The HC standard isn't backwards compatible but it *may* work, causing instability though. What class is the card ? Maybe it's too high a class for your OB to handle. If i'm correct, Class 6 is the most it can handle.
Hope this helps !

Its a MicroSDHC card and its class 4.The heating problem happens only when I play some gameloft games which are stored in sd card for a long time may b for 1\2 hour.I think I need to replace the card...
Yup. Nailed it. I have a MicroSDHC myself. 8Gigs, Class 4, but I never experienced these issues myself.
Didn't your phone come with that stock, no-name Class 2, 2 Gigs card in the package ?
You could try that before buying a new card and see if it's the same issue...
Good luck !
me too have the same problem.
I am currently charging but it still drain the batt.
My phone reach 76% on charge but it turn to 74%, how could that possible?
check the battery stat, it says that media use 44% of battery but on that time i dont play any of media. just have 2 progs that run, dsp manager and easy task killer. this thing happen when I edit my configuration setting. use cm7 #20 and nova kernel V11c by Knzo.
could anyone help me?

Try to calibrate your battery if the battery stat showing you the wrong way
And for the battery stat thing, i'm pretty sure that's a "since unplugged" usage, that means you ever open the media since it unplugged and it used 44% from the showing stat

Hi, I just purchased a razr i and I am not sure if there's a problem with the battery or if what I am seeing is usual.
I charged the battery fully when I opened it, it then discharged fully within about 8 hours. I fully recharged it, and agaiin it fully discharged in about 10 hours. It is not connected to anything (I don't even have my sim card in it yet), so cannot understand why it is discharging so quickly , especially as it is not doing anything!
As I haven't put my sim in yet (I need to get a new smaller sim card to fit it), could this be causing an issue ? I don't know if maybe its constantly trying to find a network and this is causing the drain problem.
If anyone can shed any light on what's happening here it will be appreciated. I don't want to get a new sim card CID I still get this issue and the have to change back again, and I expected the battery to last a long time based on what I have read elsewhere.
Many thanks
I had the same problem on mine. Check your battery readings, I think cell standby eats up a lot of battery when you don't have a sim on it
Sent from my XT890 using xda app-developers app
Try it in Flight mode for comparison.
Thanks, I'll give that a try and see what happens
There doesn’t seem to be an awful lot out there regarding having no SIM card inserted and rapid battery drain so I think it’s worth a shot.
I think it would also be worthwhile to download BetterBatteryStats to find out exactly where and what is draining your battery, and also to turn off Google Now (with or without a SIM).

Yes, phone manufacturers say this, that your phone will constantly look for a network if one is missing, it does drain the battery significantly. So maybe try it in aeroplane mode and see how the battery goes. Also consider how many hours the screen is on. The screen is typically the biggest battery drain.
Hi,
I've recently purchased the Samsung Note 3, overall great phone so far very quick big and shiny.
I've had some problems with the battery i've seen some weird applications using pretty much battery while i can't recall which app it is.
Battery after almost 13 hours:

I tried disabling so much features but still can't seem to fix it.
PS:
Not using any music on my phone, the only thing i do is accepting photos on Whatsapp and making some.
I've placed a SD card before in this device but removed it because i've read something about battery draining sd cards.

I had the same problem with all mj5 roms I tried to some degree or another. The only thing that made it better was xnote v.7. The media drain is non existent for me on xnote.

Even though i removed the SD card the Media drain remained.
I wen't back to factory reset and didn't had the media drain anymore.
After the reset i also didn't placed my 5000 photo's back on the phone so this could be the issue also.

I never really figured it out. It didn't resolve when I changed SD Cards, however I did put back a lot of my stuff. My wife's note 3 doesn't have the same problem on any rom I put on her phone. The only difference I can tell is I still have MI9 as the base with the corresponding modem, while she is MJ5. That is my current theory as to what causes it, but I don't want to upgrade mine to MJ5.
Anyway, Xnote solves the problem, even if I prefer other roms a little bit more. My battery doesn't drop seemingly at all unless I am actually using the phone.
Hello, I've been looking for solutions to this problem for a while now. Basically when my screen is on and system is awake the top part of my screen and backside will heat up to about 50C, it burns on the touch. Betterbatterystats gave a temperature of 52C and avg of 50. Needless to say, my battery also runs out very quickly like this, also dropping about 5% an hour when the screen is off.
Another thing I've noticed is that SDcard takes 25% of my battery usage, and when I go to storage settings, it will infinitely calculate. I mounted my storages and chkdsked them, fixed some corrupted files but the problem still persists. The only storage I haven't mounted is the internal storage, which I'm unable to do. I can't seem to connect to adb from recovery and mounting /data alone does nothing. After about 10 mins of using the phone, it becomes too hot(burns my hand) and it will shut down.
I've replaced 2 batteries so it's very unlikely that it's a battery issue. Also tried other chargers and wiping everything.
Phone OS: 4.1.2 stock LT5 before.
Did factory wipe/dalvik wipe + flash to CM11 4.4.4 and the problem is still present.
Betterbatterystats doesn't indicate a draining app, just high temperature.
Removing the external SD card and sim card had no impact.
I'm getting deep sleep when I turn off the screen, so it's not media scan being stuck. Mediascan disabled and problem still persists.
Pretty much out of ideas here, and hoping that you guys could help me out.
Any help is very much appreciated.

It's not just you. I experienced the same, as have others, for example see http://forum.xda-developers.com/galaxy-note/help/process-bug-kitkat-roms-t2834819.
If you really need Kitkat I suggest Omnirom as it didn't have the heat issues when I most recently tried it out again, about a week or two ago. The other Kitkat ROMs I tried all turned my GT-N7000 into a hand warmer/hot plate, as did some older ROMs. There are good reasons why GT-N7000 is no longer officially supported in CM - really serious bugs with very few people still willing to try to fix them. Otherwise stock Samsung + root works great with no killer bugs and huge battery life Anyone still remember when this device first appeared and it was famous for having longest battery life of any smart phone? Run stock Samsung, rooted or not, and disable all the stuff you don't use, enable the power saving mode and it still is one of the best. Not kewl tho.....:laugh:

Thanks for your response. I wasn't aware of this situation. But I was having this heating problem on Samsung stock firmware 4.1.2 too?
edit: just flashed to omnirom and it's still burning my hand.
In the team win recovery repairing internal storage gives me the error: unable to repair /emmc, so I just wiped it, problem is still there.

The heat comes when the CPU is working at max. This should be quite rare but can occasionally go on for a long time, for example if there is a lot of media content to be indexed. This would usually happen for just a few minutes after booting. Example: I use Archos video player and it indexes 1000s of movies on my home LAN via smb or upnp - this adds some overhead at startup but then settles to zero impact. It can also happen on connection changes as these are a trigger for lots of apps/services to activate/phone home/update profiles or content and so on. You could also experience heavy load on CPU if your 3G connection and/or wifi signals are poor and the device is constantly seeking better signal.
Some stuff you can do:
in stock Samsung enable power save mode - this limits the max CPU state to 1000MHz.
in a rooted custom ROM you can use any of several utilities to do the same.
This makes near enough no difference to normal use but will just throttle back the CPU when it is trying to max out.
You can disable notifications for open wifi networks.
In stock Samsung you can safely disable any of the apps that you don't use.
In rooted custom ROM you can do the same but you also have the ability to disable stuff which you need just to boot to a working environment so be careful.
Disable GPS when you don't need it. Disable bluetooth if you don't need it.
and so on....
If you use an external microSDHC card try it formatted as exfat instead of fat32/vfat. There is a horrible bug with spontaneous unmounting of the extra cards but it works better if they are formatted exfat.
On rooted stock Samsung my Note runs nice and cool and just warms up a bit if I spend hours playing games. It never gets hot like it did with custom ROMS. If I get into a mega brain dead bug eyed game session with sound high and screen on and very bright I get about 6 hours battery life. If I use it a bit more normally I get anything from 10 to 17 hours between battery changes, with screen time between 3 and 6 hours, and that includes using batteries that are a couple of years old. I never even got close to this kind of performance with custom ROMs. YMMV etc.

Thanks for taking your time to write this. I've already disabled GPS/sync and turned on power saving. Clearing the storage now lets android calculate properly, and the Media/sdcard is gone from battery usage. But it's still running very hot and draining. CPUspy says 20% on 1400 and the rest on 800mhz when I'm using it. The system is freezing often and generally really slow.
EDIT: just used eMMC check and it says I'm brickbugged :'(
type VYL00M
Ran the test but it says passed.
Temperature seems to drop to a reasonable 35C when I'm in airplane mode.
With everything on and sync off it's not going above 40C even when watching videos or something, so I guess it's all good now.
So basically what I've done to fix it:
Wipe internal storage and repair all partitions
Flash to OmniROM
Turn off Sync/GPS
Problem seemed to be mainly on the internal storage corruption, maybe related to my bugged chip.

According to eMMC Brickbug Check my Note is exactly the same as yours - supposedly "Insane chip" but Memory check passed with no problems, and guess what? It works 100% perfectly running 4.1.2 rooted. I have the full capacity of storage available to me, apps do not freeze, everything works as good as new. It is absolutely stable and reliable and terribly boring (just how I like it). It never surprises me or does any weird stuff at boot or crashes or freezes. All the hardware features work, all the supported video and audio codecs and formats work, the networking is rock solid, I can rely on my VPN when away from home, GPS gets a fix in no time, battery life is excellent, video playback is great etc. etc..
I bought my 16GB GT-N7000 a few months ago, a used item on ebay. It is an unlocked retail UK item (boxed with all manuals, paperwork, accessories etc) so no network/vendor bloatware but it was supplied by the seller with Supernexus ROM installed and was obviously suffering from the usual problems often described by users of custom ROMs on exynos. After various frustrating episodes and trials of different ROMs I used ODIN 3.09 to flash an official Samsung ICS 4.04 firmware and 16GB pit file to restore the partition table and stock firmware. Then I ran Kies on Windows XP on the "virgin" restoration. It recognised the hardware and the firmware and notified me of the update to 4.1.2. I went ahead and updated over ethernet and also captured the official 4.1.2 firmware for purpose of backup.
Since then I have tried out various ROMs and have always been able to revert to stock Samsung 4.1.2 via ODIN and without going back to the scary brickbug "insane" ICS versions. As far as I can tell the brick bug is irrelevant if you aren't stuck on ICS. After trying numerous ROMs of various android versions I am in no doubt at all that if you spend half the time setting up a rooted stock Samsung firmware as most people spend setting up ROM X/Y/Z you actually get a much more reliable and useful device.
If you need a known-good pit file for a 16GB GT-N7000 you can use this: ftp://takla.linuxd.org/Q1_20110914_16GB.pit
I had a similar issue lately. Go to developer settings and activate the cpu load display. Processes and their cpu load along with a bar graph will appear on the screen. I found out that google's music app was hanging on my phone. This did not show up in BetterBatteryStats!!!
