I have a new battery drain issue that just started a day or two ago. I have been on P76920F since it became available. Today, 35% of my battery has been used by Android Core Apps. I have attached screen shots. Any thoughts would be appreciated.

I have done additional searches and found some information in one of the Samsung forums on XDA. I have powered off the phone and pulled the battery for at least 30 seconds. I will update the post if this clears the issue.

Hello!
I am a long-time lurker of XDA Forums and had an issue that I could not resolve on my own. I am hoping the community can help me with this issue as it is completely driving me crazy and hurting my business life!
I have upgraded my Xoom 4G to 4.0.4, stock, locked, not rooted. Factory reset recently and have tried everything to my knowledge to fix the following issue.
The mediaserver is in a constant loop. There are no music files, pictures, anything on the device right now. Here are the few logs that have looped (I used OS monitor to find)
Code:
setup_dma
cpcap_audio_configure_power: regulator -> stanb
cpcap_audio_configure_power: regulator -> enable
tear_down_dma
setup_dma
cpcap_audio_configure_power: regulator -> stanb
cpcap_audio_configure_power: regulator -> enable
tear_down_dma
It happens every few seconds and keeps the tablet awake constantly. The battery is in a huge drain. I have no idea why this is happening. Any help would be greatly appreciated.
If anyone has any input I would be greatly appreciative...
Battery in just 4-5 hours has drained 40% with no use because of the keep awake.
After yet another battery cycle:
MediaServer is 3%
Android OS is 61%
Barely any use, screen is at 16%.
Please assist!
I decided to Flash my xoom back to 3.2.3 and do OTA updates all the way back to ICS.
I did not install any apps and went to sleep.
When I woke up I saw a 10% drain and "Android OS" was back to 80% of the battery usage and a keep awake of about 2 hours.
I know people are viewing this thread, but I am surprised no one has chimed in yet. I would appreciate the help.
Hi,
I am half watching the thread as am having a similar issue. I have an Asus Transformer and a HTC One X. On 11th June, my phone was roasting hot and had eaten all of the battery away. That was the first time and it has done it most days since. The Transformer has also done similar things since I noticed it on the phone, so am assuming the two are linked.
One Saturday 16th June, I factory reset the One X and re-installed the apps. In Sunday I re-imported the files from Dropbox. Was fine, like 2% battery use from the whole of Sunday. On Monday, issue returned. Only thing I did different was use it as a USB drive. AM therefore thinking those two are connected, but I don't know how to trace the issue.
I've been playing with LogCat and OS Monitor (following your post), but any advice on a way I can dig around to find what it's actually getting up to would be appreciated.
Wish I could help you tbh.....

I am also having same issue with HTC SENSATION, AOKP ROM, Android 4.0.4
I went through this with my sensation as well. It was caused by an odd MP3 on my sdcard. I suggest formatting sdcard and just keeping the bare necessities.
Any details on how you found the "odd MP3." I know this is the cause for me. I needs to know what to do to log or query mediaserver to see what its grinding on.
Hey guys,
I've been lurking in the forums for the past year and lately I've noticed that my battery has been crapping out. I'm running CM 10.1-20130807-NIGHTLY-i777 (I update it once a month), i777UCLE5, with CWM 6.0.3.5.
With the stock battery I get just about 1.5 - 2 hours of active usage. If I listen to music on it for 45 minutes, the battery drains over 30%. This is with JuiceDefender on.
I invested in two Anker batteries which worked for about 2-5 months then started locking up my phone. When I rebooted, battery went from 98% to 13%. Happened to one of my two batteries in month 2, and the second battery crapped out in month 5. Then I got a so called "stock battery" from eBay -- had the same model # and everything but didn't have NFC on it. Crashes my phone and drains the battery instantly too.
I'm wondering -- is there any way I can make these after market batteries work with my phone? I'm guessing it has something to do with not having NFC. They probably have much better life than my stock battery but I just can't make use of them.
Any tips appreciated.

You need to search for the free xda version of Better Battery Stats so that you can take a more detailed look at what is causing your battery to drain.
You can find some great information by reading this thread.
You likely have something (or perhaps more than 1 thing) holding a wakelock that is not allowing the phone to get into a deep sleep and conserve battery power.

Thanks for the tip. I will try that out over the weekend.
Any advice to make non OEM batteries work with the i777?

You can use replacement batteries, but they will render NFC useless. Only OEM i777 batteries have the necessary equipment to make NFC work.
You may want to do a search in the Accessories forum here and see what people recommend.
I have searched xda-developers and many, many other sites that I won't list, and I get conflicting answers with every thread I read. Some of the threads are dated and hope that someone can give me a clear answer.
Like many, I have poor battery life on my VZW Galaxy S3 (non-rooted). It seemed to get worse after the 4.3 upgrade, but that may be a coincidence. I have read several posts that say deleting batterystats.bin can solve this issue. I have also read several, and convincing posts that debunk that theory.
I somehow need to find a valid solution to calibrate my battery. Here is the behavior I experienced today -
8:00 am - full charge and removed from charger
5:30 pm - 63% battery remaining; moderate use during the day on wifi the entire time (extremely pleased with this, yet very unusual lately)
7:00 pm - full 4g service from 5:30 - 7:00, but not on wifi. No usage during this time. Battery down to 33% (still not too bad after 11 hours)
7:05 pm - 3% battery without any usage, phone shut off
7:07 pm - plugged phone into car charger and immediately turned it on. Battery showed that I had 56% remaining. Disconnected phone from charger as soon as I turned it on and the phone was functional for 3 more hours on battery.
So, it appears that the phone is "thinking" that the battery has less juice than it really does and powers off automatically. I need a real solution to fix this. I know that people may respond with conflicting information, but I need a real solution or cause. Is deleting baterystats.bin really a myth (see: http://forum.xda-developers.com/showthread.php?t=2256038)?? Will running the battery down/recharging/running down/recharging/repeat/repeat/repeat really work?
background - Before my 4.3 upgrade (on 4.1.2), I used to get 12-14 hours consistently. I didn't install any new applications or change any of my existing application settings, but my battery life dropped to 5-6 hours between charges, and all with similar signal strength.
Any help or thoughts are appreciated.
Hello all, I hope I'm posting in the right section.
I've been searching for info on the battery drain problem for some time now. I have used GSam and System Panel to find the culprit and observe it for a while and I think I see what is happening. Don't know if there is anything to be done but I'm hoping there is a fix out there.
Background:
Stock Verizon Samsung Galaxy S4, stock Rom on latest OTA update (screen shot attached)
One morning around Christmas time my phone drained the battery from full to 10% in about 5 hours. I had my phone in my pocket like every other day at work, I had noticed it was heating up as well. I got an error message at some point that morning about some kind of "Samsung Power Share" I had never heard of. Then I could not get the phone to charge unless powered off, and that very slowly; it was the "grey battery" problem. This problem persisted for several days and then turned intermittent then nearly back to normal, though never quite right.
What I've done:
Wipe cache, FDR, replaced USB charge port, replaced stock battery with Anker battery.
The new charge port dramatically improved recharge time and eliminated the grey battery error but I still have terrible battery life compared to earlier in this phone's life, in other words, compared to before the latest OTA which appears to be a disaster. Didn't notice any significant improvement with the new battery.
Here's what I've seen:
As soon as the battery drops below 50% the rate of discharge maxes out and this matches up almost exactly with the activity or CPU usage of the system process "krtccd." (See attached pics showing krtccd activity corresponding with increased battery drain below 50%). GSam shows the "Kernel Android OS" (in which is krtccd) using 50% of the battery where it used to be that the screen was the biggest drain, pic attached.
Is there any way to control "krtccd" as it seems to go rogue? Why does it only seem to go rogue when the battery gets below 50%?
This is a company owned phone so rooting is not an option unfortunately.
Thank you so much for any input you may have!
I apologize if this posted in the wrong part of the forum. I did do a lot of attaching for info on what the krtccd process does and why it changed so drastically with the last OTA update but I can't find much out there or in here. I don't have the option to root phone so am I such with this weird poor performance whenever the battery drops below 50%?
Thanks again, I appreciate any input you guys have.
As a follow-up, here is a screen shot from System Panel this morning showing that "krtccd" stopped activity as soon as the battery began to charge. I don't get it, it's like it spins full bore in the background sabotaging the battery for the last 50%.
BTW, the discharge last night (in my first set of screen shots) happened while the phone dat idle on my windowsill, don't think I even turned the screen on during that whole time as I was in discussion with a friend. It's weird...
Rooted Galaxy S4 (Sprint)
Same issue. Can anyone provide any information on what this process does?
Someone opened an issue report with android open source.
Issue 160689: KRTCCD Bug?
Hey guys, I picked up a Virgin LS665 from Best Buy when they were on sale a week ago. After playing with it for the last 7 days, I've noticed that the battery level never changes from 100% and on the "Battery & power saving" settings it says:
Estimated time remaining
Collecting battery info... Please wait.
If the phone is not plugged in or:
Estimated time to fully charged
Collecting battery info... Please wait.
If the phone is charging.
A quick search seems to indicate that some folks have similar issues with their G2's. I just did a factory reset, but it doesn't seem to have changed anything. Does anybody know if this is the phone or the battery that is at fault?
Thanks

Check in the settings menu if there is any update, maybe that works.
