So my bone stock Note 3 phone all of a sudden started eating up battery. Up until a couple days I could leave it for 9 hours and maybe 2 or 3 percent would be gone. Now after 5 hours it eats up 10 percent. I checked battery use details and it says Android OS is keeping it awake the whole time. So I installed Better Battery Stats and it shows that something called SMD_TTY_DS_RA is keeping a constant wakelock on my device. I'll include a screenshot and a dump file from BBS.
If anyone could help me figure out what this is or point me in the right direction I would really appreciate it.

So my battery life so far has been hugely inconsistent. The first day it was draining so fast (60% in an hour) that I contemplated turning around and taking it right back to the Verizon store.
I decided to give it a better chance than that and gave it a full conditioning cycle and all seemed well - I got 16 hours with moderate usage including an hour and a half where my screen was constantly on! I was very pleased. Extremely pleased.
So I charge my phone back up to 100% before I go to sleep then take it off the charger once it does. I drift off into dreamland, dead to the world, and five hours later I decided to check my phone for calls, texts and email.
Before I could even pull my notification bar down I saw something horrific - an extremely low battery capacity, nearly red. Checked battery usage and it said it went from 100% to 13% in about 5.5 hours.
Android OS - 64%
Phone Idle - 10%
This is the big indicator. Under Android OS, my phone (not the display) was kept awake for an hour and a half overnight. I'm really not sure what's going on here and what's causing this to happen. I haven't downloaded much - 1 game, Skype, Google Reader, Facebook, Tweetcaster, Evernote and Foursquare - and none of them showed any signs of being the culprit.
As you can tell, this is very worrisome. If I can't get more than 5.5 hours on a full charge what use is this phone to me? Does anyone know what could be going on or has anyone else run into this issue?

Thank you! I will direct my attention over there. Mods please close this thread.
Hi all,
I've had for the past couple of months some pretty dire battery life on my phone and I'm unsure as to what exactly it is thats causing it.
A couple of months ago I was on the Modaco custom ROM, i think it was version ir8, and I was able to use my phone lightly during the day from 7am every now and then, and by the end of the day say around 10pm id still have at least 60% left. At the time the longest i went without a charge was about 2 days and maybe 4-6 hours. I can't remember exactly.
Anyway, I updated the rom a couple of times, and things have never been the same. I tried reverting to the older version but things were still bad. I also tried a different rom (AOKP) which im still on now, but still things are not right.
Right now after ~14 hours on battery I have 45% left, and this is actually a good day...usually with similar use id be lucky to have 20% remaining by now. I'm unable to post images it seems. I wanted to post an image showing 63% battery, 9 hours 49 mins. Android OS > 28%, screen > 26%, phone idle > 17%, mobile stand by > 12 %, maps > 5%, wifi > 3%
Up until I noticed my battery life going down the drain I never noticed the android os using up much battery, but maybe I just wasn't looking for anything. It doesnt seem right to me however....
What steps can I take to properly figure out where the problem lies?
For reference I'm on the AOKP ROM build 40, and franco kernel milestone 4 on GSM Galaxy Nexus. Any other info needed?
Calibrate the battery. Charge full. Pull charger. Turn off. Plug back in. Charge full. Pull battery about 30 seconds. Pop back in. Turn on. And see what happens.
butter and jelly please...
You could try something like CPUSpy from the market and see what is keeping your system awake and active. Or Watchdog
Edit: I actually stopped using Watchdog because it ate more battery than what it s service was worth.
I tried calibrating as mentioned which didn't seem to do anything.
Tried CPU spy and nothing seemed odd. Most of the time was spent in the lowest frequency or in deep sleep.
I've just installed the MCR jelly bean ROM last night. And I've instantly noticed massively improved battery life, however I haven't fully restored all my apps and data yet, so I'm slightly dubious as to whether this will remain.
If once I restore all the apps and data I get battery issues again, is there anything else I could do to try and find out the route cause?
Would a log cat help?
Thanks
search the forum for betterbatterystats, if this is an app issue, then bbs will find out which app is behaving weird
I'm noticing my idle battery drain on JB is slightly higher (but not significantly so) than it was on ICS. What is your idle battery drain % per hour on JB, and with what setup (ROM, kernel, # accounts syncing, etc.). Could this be entirely due to the "update location" checkbox in Maps (possibly for Google Now)? Any other potential causes?
The first night with Jelly Bean my phone went dead overnight (from about 51%), so I went through my settings and found that it was Google Now and/or the location updating in Maps. Probably contingent on one another. I turned Google Now off and unchecked the "Update Location" settings and the second night it only lost 4% battery in 9 hours.
Note: I also had GPS turned off during that first night so I don't know if that caused higher drain but I'm going to wait to see if it will be addressed in a future OTA before using it again.
I am actually conducting a bit of an experiment to find out more about the battery drain. Im in school so my phone spends a great deal of time on idle as I work. Yesterday I got about 22hrs of battery life with 2 hours of on screen time and some light web browsing, only sync accounts is Google. That was with stock Kernel and BAMF's JB build. This was about the same, maybe even better than my stock ICS 4.0.4. However I flashed James Bond kernel (3.1.9.9) and was pulling 1day 15hrs average with the same kind of usage (maybe enven a little heavier, didnt take screenshots unfortunately). Currently I have Franco kernel (r220 384gpu) loaded and overnight with 4g left on for 8 hours I dropped maybe 5% max.
I have no reason to go back to ICS so I wont do more testing on that front but I plan to try some kernels on the rom I am currently using.
For last night only 3% for 10 hours with wifi is on.

So idle drain used to about half a percent per hour, today during work it has been 1%+. I noticed the "Keep awake" time under Android OS is over 2 hours even though screen on time is only 40 minutes. This is likely the problem right? I heard about possible issues with Light Flow on JB but I'm not sure if that would show up under Light Flow usage or Android OS. What are some other possible causes for the keep awake time here? Specifically related to Jelly Bean.
My battery drain has remained constant over the upgrade, I am getting about 2 days of battery life on idle, about 1 day on heavy usage.
Anybody else? My idle drain is now consistently at least 1%/hr or slightly more, whereas it used to be half percent/hr. I'd like to know what is causing this increase. Should I turn off Google Now? Are there apps I should try that will tell me? My Android OS keep awake time is still almost 4 times what my screen on time is...I don't think that was the case on ICS. What are other people's keep awake vs. screen on time?
Currently I have about 1hr 10min screen time and OS keep awake time of 7hr 33min. Total time on battery is 1day 2 hours and I still have 35% It seems that the kernel included with the Vicious build does not fit with my usage habbits and will be loading the James Bond or Franco kernel I had before. I feel like they had better deep sleep and governor management for my usage.
My current usage and stat on stock: 1d 16h 30m, 48% bat, 1h58m on screen with wifi is on. it's amazing
Ok, so yesterday I installed BetterBatteryStats. My phoned was unplugged for about 17 1/2 hours, screen on time less than an hour, and the Android OS "Keep awake" time was 15 hours and BBS showed Awake time as the entire 17 1/2 hours, and no deep sleep at all. However, I checked the various other things (wakelocks, processes, etc.) and even the highest item on each list didn't show more time than 10-15 minutes.
So I rebooted, checked several hours later, and it was in deep sleep for 90% of the time. That's good to see, but the issue is the no deep sleep thing keeps happening.
What can I do at this point to figure out exactly what app or process is preventing deep sleep? I've searched around and haven't seen many suggestions beyond BetterBatteryStats, which isn't showing me any major offenders.

I was thinking the same thing as you just as I was getting ready to charge my phone and wondering why Phone Idle + Maps were a third of my usage. I had 131 hours (32% remaining) on battery with 30% idle and 3% Maps, 33% screen with 2 hours 27 minutes on, 2.5 hours awake. I didn't start noticing this change until the last Maps update and turning on Google Now location stuff. Better Battery Stats also showed an awful lot of wake-ups each time I went to look before charging.
I also didn't notice this problem with 4.0.2 before I made the jump to 4.1.1 so it will be interesting to see if our increase in idle/Maps consumption is because of our Google Apps wanting to know where we are and if other users notice the same thing when they get upgrades - be it community or carrier based.
My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.
Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.
So this has happened twice recently. I'm not sure if it's the battery or an app that caused this.
Basically I left my tablet at around 40% overnight idling and throughout the day at home while I was at work. I come back around 8 pm and pick it up..battery is dead. Like completely dead, the tablet won't turn on until I charge it a bit. It's kind of ridiculous in an approximately 14-16 hour period my tablet died going from 40% to 0 on idle?
How can I find out what's causing this? I'm not really sure what changed because I haven't really installed anymore apps in the past few weeks.
@C2Q Go into Settings > Battery > and then take a screen print and post it here of what % of battery each app has used.
Should give you an idea from there. If I were guess I'd say it will be Android.System thats draining it...well thats what happened to me.
Thanks. Yeah I have tried that, I also have a bunch of other battery monitoring apps. All it says is Android OS but no specifics. I'm wondering if there's a way to tell after rebooting, what caused that much battery drain (app wise)?
@C2Q Take a screenprint and post it here..
Hmm..I'll try to get one screenshot when this happens again. Yesterday I charged to 100% overnight, unplugged in the morning before work and then came back after work about 10-11h later to see it at 99%. That was pretty normal. Wakelock detector only showed Gmail as the biggest battery usage in those 11 hours. Will keep an eye out to see if this mysteriously drains again.
What rom are you using ? It could be a faulty kernel if android os is running like crazy.
