So what does Media Hub has anything to do with JI6 modem ? Media Hub is a part of JI6 software. I personally have seen HORRIBLE battery life with JI6 modem even with Media Hub killed. I switched to JI2 modem and everything is back to normal.

ps. I compared my Vibrant with JI6 modem and software to my Nexus. With about the same light use on both phones, I had 25-30% on Vibrant and about 75-80% on Nexus after 10 hours.
[Vibrant General] kolyan:
ps. no offense, but i dont believe you.....I can make that screen shot myself. You claim that your Vibrant lasts 15-18 hours with normal use, on 3G network, with GPS ON..... How is that SO many people (70% in this poll), and ALL developers agree that JI6 modem drains battery alot, and somehow, your battery is actually better then before.....< I am sorry but I call BS on this or you are still on JI2 modem.
[Vibrant General] presence06:
It's more of Media Hub and services that run along side it. OADRM or something like that is a big drain on the battery for some reason too. If I reboot my phone, I kill this service and the DM Service. I removed/Uninstalled Media Hub and just kill the other services. I have seen better battery life now.

I don't think it's just Media Hub that's the culprit, I think it's MH and the DRM service that enables itself.
[Vibrant General] kolyan:
So are you saying that its not the modem that drains the battery ? I mean if you kill Media Hub and services, is the battery the same as before the OTA update ? or is it just a bit better but still not as good as before ?
[Vibrant General] presence06:
From my experience before the update, I could get 24+ hours easily. This was, a hand full of text, calls, twitter/facebook updates, web use, taking pictures and playing Angry Birds. When I put the phone into Airplane mode while at work sometimes or when I have no service, I'd lose 1% or less an hour.

After the update, Media Hub kept running the download manager, DRM service kept running and same with DM Serivce (Which I think was running before the update? Not sure). The first day was okay, noticed the battery wasn't as good as before but it was okay. I had to charge it at night while I slept, which is fine. But after that it kept getting worse, I couldn't make it to work with a full battery, I was actually down 10% in less than a hour. So after that, I rooted my phone, downloaded Titanium backup and uninstalled Mediahub. I thought this would help, I didn't reboot (should have). Next day battery was still ****ty, I was down 10%+ before work and by the time I got home around 5pm I was down to ~20% ( take phone off charger around 6:10am and work until 5).

I rebooted my phone after I didn't when I removed MH. Once I rebooted, went into the services and killed DRM and DM service. On my way to work the next morning, I sat at 100% until I got to work, I made a few calls and text on my way and I sat at 100%. Put my phone into Airplane mode while in the school and I dropped 1% in 2hrs...

So what I take from this is that MH Download manager, along with DM Service and DRM were all somehow killing the battery.

I'm no genius but that's what I took from it... Now I'm going on 29hrs with 36% left. I've used it the same as I always have.

Part the problem might be the Radio.. IDK. I went to bed with 72% and woke up with 60% left..? Lost 10% in ~8hrs, not unusual I guess.
[Vibrant General] Shrivel:
That's why I'm here trying to HELP. I'm just as curious as you as to why I can get great performance out of my battery, when many others can't.

But I'm NOT BS'ing anyone. What can I do to prove it to you?
[Vibrant General] kolyan:
posting About page would be nice. scroll to the button though....

i am, just like everyone else, trying to figure out what the hell is draining the battery and why. and why the hell didnt Samsung fix it.

[Vibrant General] kolyan:
do you have Media Hub ? did you kill the services ?

I used to get 8-9 hours of heavy use (mostly web and calls) on JI6 with Media Hub + Services and about 12-14 hours on JI2 modem with the same use. Both Auto Brightness ON from 8:30am to 5pm

now my set-up is: JI2 modem and I uninstalled Media Hub and killed the services. I am also running on the lowest brightness setting now.

Also ALL test are on Bionix ROM with JAC's kernel, but NOT overclocked. < both ROM and Kernel are made for better battery (at least thats what the devs say)
[Vibrant General] Shrivel:
I did remove a few of the bloatware apps, but I left MediaHub on my phone. I don't ever kill any services unless I notice that my phone is warm and some app is running out of control (only happened twice since I went to JI6; used to happen every other day with JI2, but never on original stock). I always use min brightness unless I'm in the car. Then I click on the middle brightness on Power Control Widget. I've only ever used the stock ROMs.
[Vibrant General] presence06:
This sucks and makes me sound like a douche, but I used the phone yesterday off and on and let the battery get to about 15% and charged it full.

Took it off the charger around 9pm. Used it a few times for twitter and gps/foursquare and that was about it. Put the phone into Airplane mode when I went to bed with 87% battery life. I woke up with 55% left at 8:45am....

Battery stats:
[Vibrant General] disturkis4u:
I too decided to delete drmUa.apk, drmprovider.apk, as well as media hub after reading this thread. Typically I would get around 15-16 before I'm in the 20s. My cell standby would be the biggest battery drain for me.

Some other settings I use are overclock widget (standby 200-600, wake 200-1200), Facebook refresh OFF, only one email account using touchdown receives every hour. These settings haven't changed at all from 2days ago to the time I deleted drm related apks. This is where I am currently...

1 day, 1 hour with 44% remaining. 35% voice calls, 27% cell standby. Phone idle 20%.

I tried to upload a screenshot but it says wrong file type for both .jpg and .PNG =/
[Vibrant General] kolyan:
Well after a day on JI2 and MH removed and service killed I got about the same as I usually get on JI2 modem with MH. So I still don't understand how people on JI6 and MH gone get the same or better results then I get on JI2 WITH MH......

Ps. I also noticed that my first 10-15% get dropped quickly.......about an hour of use....
[Vibrant General] novafluxx:
I've noticed more running services since the update, however my battery life seems about the same. I usually kill the MediaHub service whenever I see it as well, maybe this is that helps. I wish I could just disable that thing, or better yet, remove it. I might have to root
[Vibrant General] heygrl:
I deleted the DRM services and things seem to have stabilized, I wasn't on WiFi and battery life was OK. Not sure if it fixed anything yet.
[Vibrant General] darkmuck:
My Vibrant is rooted, but how would I go about deleting MediaHub, the DRM service, etc. as I see you guys doing? I couldn't find any sort of proper instructions on the forum (I did search!)
[Vibrant General] Tpavey:
I have bionix fusion. Media hub removed. Drm and dm services off. Beautiful widget updating every three hours and no other auto updating widgets. A gmail account that gets about 20 messages per day and one exchange account on push that gets about 3-5 messages per day. Even when I force gsm in a constant 3 bar environment my phone drains 8% power hour on standby. I need to call t mobile. My battery blows.
[Vibrant General] presence06:
Someone posted before that they removed the Task Manager that was installed with JI6 and it seemed to help. Has anyone else done this? I've removed all the crapware T-mo/Samsung has put on this device. Just curious.
[Vibrant General] HotShotAzn:
Few different ways:

1) Download the free version of Titanium Backup. You can remove from there.

2) In a terminal, enter in the:

mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system (press enter)

cd /system/app (press enter)

rm [file name] (enter)

3) Use Root Explorer and go to system/app. Delete the files from there.

Where is omadrmconfigservice located? I see the name as com.sec.android.providers.drm but dont see it anywhere I can permanent remove it (besides stopping it in the app settings menu).
[Vibrant General] mr2t32:
Just out of curiosity, for all that are having battery drain problem, are you guys running any IM apps or Gtalk?
[Vibrant General] Tpavey:
Ihave not lodged into talk. I just disabled the service to see I'd that helps. I feel that should not need to be done though.
[Vibrant General] dekka83:
Disabling gtalk and gvoice does seem to improve the problem by quite a bit, but I remember this was not an issue before the update.
[Vibrant General] heygrl:
Google Talk has always been a battery drain
[Vibrant General] mr2t32:
gtalk is not as bad as other IM apps, but it still pulls quite a bit to cause the battery to drain at a fast rate. This will all be solved once we get 2.2 froyo because it'll have the push capability. I tried the froyo rom and with the IM apps that are made to take advantage of the push, the battery does not drain like it will on 2.1.
[Vibrant General] martin0641:
People that have installed Fusion 1.1 (Comes with the JI2 modem) and then patched JI6 on top of it are posting over 24 hours of battery in the forums.
[Vibrant General] Tpavey:
Those are usually people who had good battery life with ji2. I may try it anyway.
[Vibrant General] pavvy:
I'm skeptical that these services affect battery life (unless you're actually using Media Hub). When I let the phone sit in airplane night overnight, with all stock services running (including a few from apps/widgets I've installed, such as Battery Notifier), I get a 0% drop in battery level. (Only when I leave my "Missed Notifier" service running, from a notification app I use, do I see about a 4% drop over the same period.)

Now, maybe throwing the phone in airplane mode "stops" a drain that these services cause when the antenna is on (I don't know anything about it, really) -- but don't know why that would make a difference, since (correct me if I'm wrong) they're not "doing" anything either way (again, unless you fire up the Hub - right?). And I will say that when I have tried disabling those services, I haven't noticed any "improvement" in battery life during the day.
[Vibrant General] asianhookr:
My battery was terrible the first few days after the ota update, only getting around 5-6 hours of life. I was turning all the functions off completely and still battery was terrible it would drain overnight. Called T-Mobile got a replacement battery drained it completely fully charged it and it works perfectly. It's been 6 days and I am averaging 20+ hours without charging. I can leave GPS, wi-fi, and screen set to auto brightness with no problems. Basically what i'm saying is get a replacement battery from t-mobile and you should be able to use your vibrant the way it was meant to be used.
[Vibrant General] Tpavey:
Got one on the way. The guy was surprised it let him send me one as I'm more than ninety days out. Hopefully I get the results you did. Yesterday at work it died at 6pm after being at 90% at 8am, 2g only.
[Vibrant General] sandhuxda:
Running Bionix 1.9 w/stock JI6 and no mods.

I stopped the DRM service by going into "Running Services" menu and later my wife reported that podcasts and pandaro do not work properly (lots of stuttering). Stock music player works ok, though. I looked at Epic 4G forums and people have reported similar issues of podcasts/pandora apps being broken after stopping DRM services or uninstalling DRM and Media hub.

Any similar issues here?

Just to cross-seed a thread...

Search threads for: Critical SyncManager Bug in JI6 (can't post a link. NOOB and all.. )

Nutshell: "There is a critical bug in JI6 with the SyncManager and Exchange Push synching. Periodically it will turn into a run away process while synching. The process will get stuck downloading and uploading over 3G.

It is critical because it makes the phone very hot to the touch, rapidly drains battery, and uses a lot of data. The process will not stop until the battery is dead. It happened last night to me, and from a 100% charged battery, I woke up to 5% while on the charger and a critical low battery warning. Looking at T-Mo's data tracking, it used 60MB of data.

Has anyone else had this issue? Where can I officially report this issue to T-Mobile/Samsung?"

I think this is worth investigating. I turned off/deleted my corporate mail settings and I'm back to normal (for me) battery life. Seems like a smart developer with a heart of gold could fix this. Sadly, I'm neither a good developer, nor do I have a heart of gold.

A work around depending on how secure your "work" email is, is to create a rule and have it forwarded to your gmail acct that you all have. :) Poor man's "unified inbox". Discuss...

FYI... Odin JI6 flash, JI2 modem, Bionix Fusion 1.1 ROM, back to 3G, all DRM .apk's removed via root explorer, all sync to manual.
[Vibrant General] heygrl:
I deleted all DRM related services and my battery life is good.

I always have Trillian running, a few Social Network clients running, did some light surfing, played some music, had a few phone calls, Overclocked at 400-1000MHz.
[Vibrant General] Tynen:
How do you delete services in Android? I've deleted and uninstalled all DRM apks in system/app but the OmaDrmConfigService is still running.
[Vibrant General] presence06:
Use Titanium Backup or another backup program, heard some say MyBackup?

Anyways, use one of these to go through and find DRM services. Read through previous posts about what not to delete and then reboot your phone. Check to see if they startup again.

Good luck.
[Vibrant General] d_bot:
i will have to agree with the Email.apk issue. I had exchange set to push, and had horrible battery life even after removing all drm crap. changed my exchange settings to 15 min checkin, and went 19+ hours on a single charge, granted 8 of those ours i was sleeping but still...
[Vibrant General] :
i removed the 2 .apk files mentioned in the beginning of the thread and the associated .odex files. however, on the aforementioned epic thread, people also state that removing the associated files in the applicationg manager after doing this (com.android.providers.drm / com.sec.android.app.drmua / com.sec.android.providers.drm.) started to cause issues.

my question is, are you guys just killing the services, are you removing just the apk files or are you removing the apk files and the associated items in the application manager? i want to get rid of them but don't want any problems like the epic users mentioned.
[Vibrant General] regP:
I completely removed them but get FC whenever I tried to play any audio so I ended up putting them back. Having them gone didnt seem to make much of a difference in battery life anyway.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Antonyjeweet:
I just flashed a battery mod on my galaxy s.

But i think i downloaded the Wrong one!!! When i did a reboot, the process 'android.phone' stopped working. Mmmm.. OK.

Tried a factory reset through the 3 button menu. Well now it does not do anything, i can see the boot movie, but then i get a Black screen with an heartbeat on the vibration thingy.

I did not panic and tried to flash an other firmware. Well it did not work. I see the boot movie, but then the screen blacks out and nothing works......

I searched for this, but i didnt get a good answer on how to solve this.

So if anyone is kind enough to help me, and tell me what to do in simple steps.
[Galaxy S I9000 Q&A, Help & Troubleshooting] Cartier23:
The same here. I used version D for JP6 & the 2nd method.

I had to reflash the softwear.
[Galaxy S I9000 Q&A, Help & Troubleshooting] TheNikkoMan:
Exact same problem with me, had to reflash. Could someone tell the guy who has the battery mod thread?
[Galaxy S I9000 Q&A, Help & Troubleshooting] petzku:
1st. You need to flash a fresh firmware I suggest a official one so you can download the latest JP6 from kies without knifing the registry. you can get those firmwares from http://www.samfirmware.com/WEBPROTECT-i9000.htm but you need to register first. And here are the intructions how to flash http://samsunggalaxysforums.com/sho...and-and-flash-newer-firmware-to-your-Galaxy-S

2nd. After a succesfull flash go to recoverymode (shut down device, hold: vol-up, home and power)

wipe cache and do a factory reset just incase, and boot your device.

3rd. Install JP6 through Kies :)

edit:

BTW im a noob who did just this after i messed my phone to a state like mentioned in op :) So i dont take any responsibility about any damage you do to your phone. I did something like this and now i have official JP6 inside my sgs and its flying :)

[Droid Incredible General] 1967ls2:
Root and use "SetCPU".

[Droid Incredible General] SR3TLAW:
What's a strait forward guide to using set CPU.
[Droid Incredible General] ozzman54:
Here is the official setCPU documentation: http://www.pokedev.com/setcpu/

I am using the Adrynalyne Custom Kernal (v2) which defaults the cpu governor to Conservative in setCPU. For my setCPU profile, I only have one entry that underclocks to the slowest speed when the screen is off.
[Droid Incredible General] Deltaechoe:
I have it set to run at conservative from 600 so mhz at 50%, 300 at 25% and powersave and lowest clock setting when the screen is off on powersave.

It does edit a lot of files, so you may have to apply it more than once to see all of the changes due to a bug in metamorph.

[Touch Pro2 CDMA] Kooper113:
Hi guys,

My girlfriend somehow has borked her phone.

From what she's explained, she used Task 29 to wipe her phone, or something to that degree, and then tried to flash a GSM ROM to it. However she in on Sprint, so I assume it's a CDMA phone.

As of right now, the phone appears off. If you hold the power down, nothing. If you take the battery out, put it back in, and hold Vol Down it'll boot into the bootloader (I believe that's what it is, the colorful background thing) however the bootloader soon goes away and back to the black screen.

Sometimes the phone will randomly boot up to the HTC logo, and then back to blackness.

Does anyone have any idea what she's supposed to do at this point? Or what I should do to get a ROM on there? I have 0 experience with Windows Mobile roms, so I don't know what happened or what to do next. Guidance of what happened and what to do next would be appreciated so I can solve this issue and understand the situation past 'is it borked' :p

Thanks everyone

EDIT UPDATE: I figured it out. Her battery was dead lol however USB charging wouldn't work. I happen to have an external charger hah so I saved the day. I was now able to boot into the bootloader, have it stay there, and put a ROM on there. Easy Peasy.
[Droid Incredible General] GatorsUF:
I am not sure if this is related to Ultimate Juice Defender or not. The settings are a bit confusing on that to me. I turned off the "perfer wifi" and made it so UJD doesn't mess with my data connection "I THINK".

Either way the only way I noticed is if I use Grooveshark and turn the screen off. As soon as the song that is playing is over, it fails to play anymore songs and gives me an error for the rest of the songs in the playlist. Alternatively if I leave the screen on it will play everything fine. As you can tell this is a drain on the battery so....any ideas?

I don't have any experience with Juice Defender, but you wouldn't happen to have "Enable always-on mobile data" unchecked in Settings>Wireless & networks>Mobile networks would you?
[Epic 4G General] troyolson92:
Until android 2.2 I can definitely say that using a task killer wisely is needed for some users. I use advanced memory manager for root and have set to (bottom up) 150, 140, 135, 120. In my case it doesn't ever free up memory fromm my storm live games or opera. So I use ERAY to auto kill all games and browsers when screen goes off. This Is A NECESSARY. these programs will drop my memory down to 110 which gets sluggish.

Don't let people fool you. Using task killers wisely IS a good idea.
[Epic 4G General] megabiteg:
I beg to differ.

I was a big believer in Task Killers and I used them from the G1 all the way to my Epic 4G and I discovered one thing. It's Android's nature to have programs in Dormit state in the background, what really sucks is to have porgrams in the backgorund consuming processor time, not memory.

I have uninstalled the Task Killer software and I've been task killer free for more than 2 weeks now, and I have seen more improvements. I notice in my task killer days that the phone would become somewhat sluggesh after 112 - 110 MB becuase the programs were restarting in memory and thats when the impact on the processor was being made (thus draining some more power).

After uninstalling task killer, I installed Watchdog which can kill apps but its main focus is to find the programs that will not be dormit while not being used, so far i've seen a jump in performace and longer battery life. I notice that everytime my phone may become sluggish there is always an nonused / nondormit software that needs to be killed, but its just one, not a bunch.

Also killing apps is not right for the phone, this can corrupt the services and programs in the long run.

I don't curse the people who use task killers, but I just don't think that we need it, specially with such a powerfull phone.
[Epic 4G General] baconnbitz2010:
I had advanced task killer installed but I'm interested in watchdog.

Why is killing apps not good for the phone but allowing bunches of apps is good?
