Dracula?? (com.lge.dracula)

So hunting through the bloat I chance upon this interesting kibble. Using nobloat I disabled it and thusfar no issues...But doesn't anyone know what the heck it is?
Google wasn't much help in that regard.

Maybe it is the dreaded "Battery Sucker" we are all searching to disable/stake through the heart/flame to hell, cut it's scrawny head off???

that's weird, i just checked and mine has com.lge.wolfman

Imagine it is the reason why the battery life is so horrible. And if so, why is it there to begin with? hehe

makes us actually wonder that question with serious thought, just WHY is it there and named so? i can actually say i saw battery life decrease when i enabled it. i could leave my phone unused in my holster all day and see little dropoff, but when i re-enabled com.lge.dracula i actually lost 3/4 of my battery power by mid-day!! coincidence?? maybe....LTE affiliation? possibly.... "battery sucker"?? certainly.

Sent from my LG Nitro HD

Can someone run it with the others over at Skyrocket's forum n see if it's also available on their phone. If it is, then it might be LTE related.
Repherb, when u disable it, did u check to see if your LTE will work or not?

i froze dracula through Titanium backup , currently connected to LTE, no problems here, restarted to make sure. it is still frozen and LTE connected.
LG Optimute LTE. P930.

Who can we inquire to here in XDA to research on this random file? Can someone from XDA investigate with LG to find out the purpose behind this file?
Also, is there any possibility of some screenshots to show the difference freezing Dracula does to the battery life? This way we can prove that this file (or Wolfman) does suck the life out of the battery and is the reason behind the horrible battery life.

Froze it, no discernible difference in battery life imo.
Ran a video playback test, the extrapolated playback time at 40% brightness in airplane mode is about 5 hours 20 mins. The same test on my SGS2 got slightly over 8 hours.

LTE works fine when disabled, i am going to dive into the OS to see what calls this. btw: after rooting with DoomLord v3 zergrush, i am getting a serious amount of FC with nothing disabled using GO launcher. anyone else having this? just a [Q]... not trying to cross post...
**************UPDATE******************
after running top, i found that "lg_fota" (OTA updates) calls the Dracula process. hope this sheds some light on this elusive process.

I hate to reopen a two year old thread, but since Dracula is actually undead, I just have to ask: has anyone figured out what com.lge.dracula is, and if it's safe to chuck it?

Htc one x battery dies overnight...battery stats show android os use the most.

Hi,
I have been having a problem of battery.
1. Battery dies from being 100% overnight.
2. Phone randomly shuts itself having more than 40% battery but shows 0 battery when it restarts.
3. Phone restarts quite frequently when taking a picture. (once a week)
Please let me know what should I do to solve the problem. Thanks in advance.

I've got the same drain problem as your number 1, but not the other 2 issues. The funny thing is it only started a week or so ago, before that it was fine. I've been running the Viper rom, and Faux kernel without a hitch for over a month up until now.
I used to get a day out of the battery, and 2.5-3 hour screen on which was fine IMO, but not anymore.
I'm wondering if a recent app update has caused the issue, just speculating though, also it seems to be that the drain is happening when I'm not using the phone, when I do use the handset for whatever it uses the battery as normal.
Not trying to hijack your thread, just thought I'd give my two pennies worth as I'm having a similar problem.

I think you may be right because I have had the last 2 problems since a while and gave in HTC to repair the phone but it still hasnt been solved and I have got the first problem since the last week itself.

Did you manage to install Better Battery Stats? Leave your screenshots here when it happens again and we'll be able to help you much easier

I had an Arc before, so i thought maybe this will help:

You have enough network in your area. I had this issue and change the Network selection to manual which took care of the issue.

You seem to have a lot of applications running and something is keeping your phone awake. Any awake time when the screen isn't on also is an application using your phone.
Go to the play store and check the permissions of your downloaded apps, any app that has the permission to keep your device awake is a candidate for your problem. Uninstall them all and your problem should be gone, re-install one by one and see when it returns.
Regards
Phil

The problem occurred again. I have attached a image of the battery stats.

Need a shot of the 'partial wakelocks' category.
Also, don't stick them altogether into one pic, the board shrinks it massively. Just upload them individually

Here is the individual files

Looks like it's the radio causing the majority of your drain. How is the signal in your location? I see you've switched from EDGE to 3G during the screenshots... if the 3G signal isn't great then it will cause battery drain searching. It might be worth forcing your phone to either 2G or 3G only and seeing what happens.

Actually I just switched to 3g in the last couple of days. I only had 2G previously and the problem still occurred. Its funny that it happens only at night.

I think its the time for a fresh start. Format your phone and start all over.
So, how much will it takes you? Less than 3 hours? I'd say go for it.
At lest it would give you less headache and hopefully more battery.
Good Luck

I've had this problem before too, with baseband and alarm wakelocks.

CELL STANDBY battery drain solution on stock

After being frustrated for a couple of weeks and wanting to return my s3 due to overnight cell standby batty drain of around 40-50% (from full charge with no use overnight, I finally called Samsung tech support and they told me to power down, take out the battery and reinsert, and use the original charger ONLY (i was using a old clamshell phone's charger that I found lying around rather than the one that came with the phone. I freakin can't believe it but it solved the issue for me!!! I only lost about 4 percent overnight. I was soooo pissed before, but now I love my s3 again )
Curious to hear if this works for others who have also been frustrated with this awesome device...

That's been a known problem since the beginning and there was a fix zip floating around, flashed it and my cell standby is only ever 1-2% max 6%
Sent from my SGH-I747M using xda premium

Well just restarting my phone works to "fix" the massive battery drain issue (presumably because cell standby is using about 60% of my battery) but it will be back in a few days. While I do sometimes use more than one battery charger,I don't think this is related to using something other than the original charger but that is something I can test. Thanks for that tip.
This is one of the 3 big problems I have with this phone (the others being random loss of service presumably due to LTE network deficiencies and the face proximity sensor acting to disable the screen whenever I try to touch the screen with my finger). Since mine is a replacement phone for another S3 with the exact same issues, I'm assuming there is no real fix for these problems (for a stock phone). Yes, I have learned to hate my phone...

The Cell Standby Fix posted above me...which I use as well...does not fix a DRAIN...it fixes a false reporting of the drain. Charger has nothing to do with it. That was a fluke or a misrepresentation.

i turned off the voip services that i had running and now it discharges only about 15-20% over night

Do a search for gsiff_daemon. That is most likely the cause of your problem and while I can't say for sure, I suspect the charger advice worked coincidentally due to the problem being fixed temporarily by powering down and restarting.
Sadly, I don't know of Samsung admitting to this issue and it looks like even the jelly bean update does not fix it.

I get the cell standby misreporting, not adversely affecting life at all. I did flash the fix and the cell standby consumption is now reported much lower, but I seem to be getting a slightly higher battery drain. sitting idle I generally drop around 2% per hour due to syncing and email push. after flashing the fix I'm up to about 5% per hour. I backed up right before this install so I'll probably revert back...
any idea why this would be?

I highly doubt using the Cell Standby reporting fix is causing the 5% drain Russ77. It's a proven fix without reported side effects. I have looked at the code myself. It simply alters a certain math value of 34 to 3.4.....a coding typo! Once again, probably just coincidental timing. But read on....you may have this bug if you run a stock rom...
Here is a full test report on the gsiff_daemon that I performed yesterday with details on how to reproduce it, and how to work around it. Hopefully some smart cookie will look into it and fix the code from the inside!

Check out the thread linked to by themadproducer (I post up) for more details. But basically, yes, if you have root you can rename the file. I just did this a couple of days ago. I haven't noticed any issues. Maybe GPS lock takes a few seconds longer, but it's hard to say if that's true or just a coincidence.
It does seem the gsiff_daemon issue is triggered by a hot reboot, which sometimes happens spontaneously. I haven't had one since I rename the file, but I don't know if renaming that also affects the spontaneous hot reboots, which are annoying in themselves. But at least it won't cause the phone to eat through battery and turn itself into a mini hotplate...

Cell standby is the one which is concerned with network connections.
The solution that would work can be changing the SIM card. Get a new SIM from your operator and throw away the old one.

[Q] GN2 Battery Performance Degradation after Update

Hello
I have a AT&T Note2 that I got late November. Battery Performance was fabulous. I just recently got the update to 4.1.2 OTA and there was some sort of upgrade or maintenance just prior to the 4.1.2 update.
I immediately noticed a difference in battery performance. It was substantially less than what I had on 4.1.1. I cant get any straight answers from Samsung or AT&T, there is no comprehensive log for the update so its hard to figure out whats going on.
Same software load as on 4.1.1. I did notice that after the update to 4.1.2 there were substantially more items in manage apps> running than what was in 4.1.1.
Samsung claims the root cause is the update to the OS and a change to the wifi radio and software.
Does anyone know what really is going on. At&T is a lost cause and no help whatsoever.
Thank you

I will be interested what you find out as I am experienceing the same issue. I went from 95% to 65% overnight doing nothing (WiFi on). Earlier today I was losing about 2-3% battery every 15 minutes doing nothing and did some research. All I could find out was to turn off all location services and since I don't get Wifi at work, turn off WiFi while here. This helped some, but still would like to find out what is going on. My iphone was a battery hog in the end of its life and my new GN2 lasts barely as long as my 2 year old iphone did. Not a happy camper right now.

Hi, I'm hopeful one of the Senior Members or Mod's will run down a answer as well as a comprehensive change add-delete and enhancement log regarding the 4.1.2 update. All I can say is I have not added anything my daily use is the same..no games. I disabled all the att bloat wae other than hot spots. I sort of paid attention to my running apps in 4.1.1, and now in 4.1.2 there are many more things theree that wernt prior to this update. I didnt have to disable anything prior to this update.
The answer is not in disabling bloat apps. The answer is in the log that shows what was done with the update.
I hope someone can get that because it holds the key to the answers we are looking for.
Who knows maybe one of the developers will read this thread and be able to help.

try a battery pull and obviously reboot. Download the Gsam battery monitor from the market. I think it is free. It dumbs down a lot of stuff and pretty much tells you what is taking up your battery. It does a much better job than the stock battery checker. After an hour or so, the longer the better, it will show you some apps or processes that are the culprit.
Battery stats app is a paid app in the market but I think it is free on this xda site somewhere for members. That appears to be a very comprehensive battery monitoring apps with wakelocks and it gets very complicated for a novice such as myself.

can you provide additional details on your situation, for example:
what's your baseline comparison, e.g., before: 18 hrs use with 4 hours screen time, after 13 hours use 4 hours screen time
are you rooted (i suspect not)?
have you gone into Settings->Battery to see which apps, etc., are using your battery?
do you have a lot of music, pictures, etc on your phone?
not an answer to your question, but... have you considered performing a hard reset on your device and then testing battery life with at clean slate?
looking at your battery stats is a better indicator of what could be causing poor battery life. i'm on the same release as you and my battery life has been the same if not better. also download better battery stats to see if you have wake-lock issues. i'm averaging 16-20 hours per charge with 6-9 hours screen time, about 150 emails daily and 35-90 minutes in phone calls.

So yesterday at 19 hours of use (maybe 2 hours total of emails, web surfing, and using a couple apps, music for an hour at the gym) I still had 32% left. Not bad. However, my wifi was off all day, even at home, and I kept my location services turned off. So tomorrow I am going to test it with Wifi on at home and my location services and see what happens. The Gsam battery app i used yesterday was pretty cool although at first I wasn't sure because it said that the app was using 15%. But as the day progressed it never went over 4%. Still new to the android platform, but learning.

I APPRECIATE the response however I would like to know what was done with the 4.1.2 upgrade, what changed, enhanced or whatever as well as the AT&T maint just prior to the 4.1.2 upgrade. Nothing was disabled, I was runn8ng the same exact software load, same apps, no games, and wifi wS constantly on. While disabling bloatware, shutting down this and that, turning off wifi at this point is helpful, its not a acceptable answer as to what happened.
This forum has some of the most respected developers and computer genius's around. Whenever you ask for something and everyone else comes up empty, the first thing you hear is go to XDA.
My Galaxy Note2 had the most incredible battery time of any device I've ever owned prior to the updates. Im also pissed because I didnt even know that the red and grey arrows and the connecting to dnr server was AT&T doing a update. There was no forewarning.
The Note2 is still fabulous to me, I just want to understand what has happened and why. I am not asking for a say in what they did, certainly this is my phone, I believe that I should be entitled at least to know what transpired.
There should be no problem producing a comprehensive change log with a lay person level explanation.

I was getting 2 days off charger with 8 hours of screen time and suddenly the battery doesn't seem to charge past 50% and I didn't do a single thing to it but tonight I am cleaning everything out and starting fresh because something odd is going on

I think the key to many answers is 2 items.....a log and explanation of what occurred in simple terms regarding the 2 updates. There was a no warning automatic att update done just prior to and then the actual 4.1.2 update itself. My gut opinion is something was changed with wifi and how its handled along with some other software changes.
I feel like. Dog chasing my own tail...disable this, disable that...bull...nothing was disabled and wifi was always on prior the updates.

Help, extreme draining

Hi, i bought one moto z play, almost 2 months ago, and the battery was excellent, you can see on airplane mode, idle, not using it, the phone lates more than 17 days, and had 23% of juice left, after that, i boight another one, both are used, but this one, only last 2 days on the same conditions, airplane mode, even safe mode, not using at all, just 2 days, drains like 2% per hour without even touching it at all, what can i do?

What does it matter what happens when you never use it? And why buy a second phone if you already have one that lasts great?
Just sell the second and start using it like normal people. Nobody can tell you why that difference is and it doesn't matter. They have to last under normal conditions, but what you are doing is pretty much waste of battery. Letting it lie around in airplane mode for days is simply stupid. Then you could just turn it off

Seems like a reasonable test of baseline battery drain to me. I get less than 2% drain per hour with all my background stuff on with my MZP. My old S6 (notorious for bad battery) gets like 3% per day in airplane mode with no screen on time.
Just because his use case isn't your use case, doesn't mean what he's doing is stupid.
OP, I'd be inclined to think you have a hardware issue - you've eliminated all the normal software side stuff that typically is responsible for battery drain.

Exactly, it was just a test, obviusly under normal conditions the drain Is Worst, only 3 SoT and 9 hours of battery, if you compare the two phones, one drains 2% and the other 0.1% por hour, that it's not normal.

If is not hw issue, something is draining battery in background. Have you tried factory reset? Compare settings on both phones, wifi/bt scan, SIM is inside on both, sd card?
Anyway, try to make both phones exactly the same from hw and sw perspective. If you haven't already.

Maybe put a CPU monitor app on both phones, let them both run in the same condition for the same time period, and see if the histories match? Not really sure how else to look, since you said safe mode didn't fix it.

the one with the problem has the december patch update, the good one, the november patch, thats the only difference on both. already tried factory reset, wipe cache, safe mode, even on safe mode, the 2% per hour draining persist.

You can try to upgrade good one to December patch to get the same batter life result
If there's no other difference, then looks like that is hw problem. But I'm still suspecting that you are missing something.

good joke, but im not gonna take that risk; cant think what i would be missing; i think ive tried everything except for a downgrade, but i read somewhere it cannot be done, the phone is on 7.1.1.

Do not downgrade. It is doable but next upgrade (OTA) and you will end up with brick.
I've already asked you, both phones are with/without SIM/sd card?

Well, if both phones are the same from hw and sw perspective (except update on "bad one") then most probably cause is hw or update.
Do not try to downgrade, 8.0 is under SOAK (quite long already, but still has issues) and you may try it when is ready (don't flash leaked SOAK, please).
As said above, most likely is hw issue. Sorry for that.

camera app left running?

Seems like a reasonable test of baseline battery drain to me. I get less than 2% drain per hour with all my background stuff on with my MZP. My old S6 (notorious for bad battery) gets like 3% per day in airplane mode with no screen on time.
Just because his use case isn't your use case, doesn't mean what he's doing is stupid.
OP, I'd be inclined to think you have a hardware issue - you've eliminated all the normal software side stuff that typically is responsible for battery drain.

Your second pic says it's running. Sorry if I misinterpret.
