I have read these forums for a long time but this is my first post. I recently updated the JI6 via the official T-Mobile over the air method. I have been on JI6 for two days now and have noticed that my battery life is terrible. Usually I am able to make it through a day of average use without any problems and I charge at night. Yesterday my phone did not make it through the day and it was a low use day at that. When I got home from work I started charging the phone, before bed I unplugged it and figured it would be no problem to just leave it in standby all night, my previous experience was that a night of standby only dropped my battery by a few percent. When I got up and looked at my phone before leaving for work it had already dropped to 21%, I looked at the battery usage statistics and found that Cell Standy and Phone idle had leapfrogged over display which is usually the biggest draw of power and were now using significantly more power than even the display. Also I do not live in an area of poor cell phone reception so that could not have contributed to this.
My phone was pretty much stock besides being rooted to run the WiFi tether. My wife also has the same phone and she said she is experiencing pretty much the same thing since the JI6 update.
Below is the list of the top 4 batter using processes were on my phone and their percentages.
Cell Standby 41%
Phone idle 30%
Display12%
Android System 9%
Is anyone else experiencing similar battery usage since the JI6? Is there a known problem with this JI6? Has T-Mobile or Samsung acknowledged this problem? Any suggestions for fixing the problem at least until Froyo comes out?
Perhaps others can post their experiences with battery performance post JI6 here as well so we can get a consensus.
The radio in JI6 is stronger than previous versions to help with reception. That being said, it drains battery more. However, the stats your provided seem to point to you having apps on your phone that are pulling internet information too often. My cell standy or phone idle is never higher than my display and I do use widgets and apps that update a lot.
There just seems to be a bug somewhere that causes random drain, I've seen what people are saying about and I pulled the battery, it stopped draining for me until I guess I trigger it again.

I do have some apps that are pulling data down from time to time, but I have been careful about setting these apps to not update too frequently. Also last night I specifically went in and closed any unwanted running apps, I think the only apps I left running were Seesmic, K9 Mail, and Gmail.
This thread is precisely the reason for why:
a) I finally registered to xda-developers for support
b) I decided to root my Vibrant
I received the JI6 OTA update around 5 AM on Wednesday, thinking *oh sweet this must be 2.2* I didn't hesitate to install it...the first 24 hours after didn't seem to show much signage of battery drain, but by Thursday morning things seemed...off.
6:00 AM - 100% charge, fresh off the cord
Around 11-noon - 15%, low battery notification pops up
This was by far the quickest drain I've seen, and even though I've only had my Vibrant for a month...right out of the box I was getting spectacular batt. performance with light-moderate use + wifi + sync, lowest brightness*(auto off), somewhere around 24-30 hours.
My initial reaction was to reset to factory, only to discover here that it did absolutely nothing to remove the JI6 update.
Now, post-root I've been reading through similar threads about the OTA effects and finding all types of tricks to extend the batt. life. Today the battery hasn't been as bad (with nearly everything off...sync, intervals, gps, blah blah), lasting around 11 hours. Not sure if there's any fix in sight, though I'm not really anticipating it reading how the cell standby / baseband is cranking out more power and in effect more juice.
My battery is about the same as before, getting 24-30 hours out of normal use. I'm currently 14.5 hours unplugged sitting at 42%

Flashed JI6 via Odin, and my battery life has sucked since. Talking on the phone kills it especially fast. I talked for about 45 mins yesterday morning and the battery gave out after 7 hours. Today it at least lasted 12 hours, but that was with pretty much everything turned off. Anyone flashed back to JFD? It's not like JI6 brought anything to the table.
My battery drains while idle after the update. Yet my wife's phone battery is fine. Hers is stock and mine is rooted with mobile AP flashed. I even reconditioned the battery.
Tonight I decided to flash bionix 1.91 rom to see if that would fix the battery drain issue. So far it's looking good. I'll know better tomorrow after a full charge.
JI6 installed Media Hub, right?
Sprint Epic users found that when Media Hub was installed on that platform a couple of revs back, it loaded a DRM background service that is constantly running even if Media Hub is never used. It is now pretty standard practice among knowledgeable Epic users to stop the DRM service whenever the phone boots. Many rooted users go further and delete it.
Vibrant users might try the same methods to improve battery life.
My battery usage has been fine. I installed through mini kies though rather then the ota.

It totally sucks for me. I have tested it throughly this past week. Ran JDF and left it idle over night, barely lose any battery life. Update to JI6 via kies mini and lost 30% over night while i'm sleeping. I also tested the various versions of JI6 posted on xda and all of them give me horrible battery life (losing 3-5% per hour doing nothing).
I'm flashing the JDF modem file on the JI6 from kies mini. Will report back...
Again I'm completely confused here. Running stock JI6, went to sleep last night at 24%, woke up this morning at 21%

I removed mediahub via titanium and a bunch of bloatware while I was at it yesterday morning, I can report that last night before dozing off (11:45 pm) battery was at 90%, this morning (8:30 am) its at 63%...37% loss in almost 9 hours. Only wifi on throughout the night:
Display: 41% (brightness 0)
Cell standby: 27%
Phone idle: 19%
Android system: 7%

That makes no sense, if you're on WiFi it wouldn't be the cause of this. Are you sure it's set to be on WiFi 100% of the time/when the screen is off?
That's ridiculous, something is awry

Just kidding stupid me, just checked wifi sleep policy...changed it to 'never' now. Yeaaa that might've helped lol.

Switching to bionix 1.91 stock kernel solved my idle battery drain issue. I was losing ~4% an hour and now with bionix it's not draining. Unplugged the phone this morning at 100% and an hour later it was still at 100%. Same as before the JI6 update. I'm happy now. Bionix is smooth as butter.

I'm contemplating this option, how long have you been on bionix now? Any stats on batt performance afterward, hours?

After the update I got horrible lag and bad drain. I'm talking 4 hours on average usage.

Does anyone else see the irony or possible logic that Samsung gave us a stronger modem that uses more power and a new task manager to monitor what else is running draining power with the Ji6 update? Granted there are better task managers for root, but kinda clicks in my head.
Also after all my settings have been checked, apps, wifi sleep (used OCLF), widgets and internet, syncing frequency, wallpaper etc. I used Rom Manager to recalibrate my batteries. I thought that the battery data might have been wiped during the update and at first my phone behaved like it.
All good now. I'll never have the stand by of a flip phone, but it all seems reasonable. I use my phone a lot, a real lot. I go through 2-3 charges a day, mostly 2. I have extra batteries also. Stand buy time almost seems better, but I have not recorded data and I have made many changes.
Theres a good thread a dude put up in the Vibrant general section about his anal battery saving habits, he uncovered more ideas and things I didn't know. Hes admitedly extreme put its a good read. Also a couple of threads on how to recal the battery, some disagreement there so I did not chime in here with specs.
I am running the stock DL30, and like a lot of others, I have experienced pretty poor battery life. Took my phone off charge this morning at 100%, and about 3 hours later with very little use, I'm at about 80%. Decided to take a look at the services running, and SnsService is constantly restarting. Could this possibly be the culprit of my poor battery? Is it safe to stop it? Or is there something I need to do so it's not restarting? I know the service has something to do with Social Networking Services, but that's about the most I could find.
I already tried wiping the battery stats at 100% charge, draining to 0% and wiping the battery stats, deep charging (drain to 0, then charge to 100% powered off), and a few other things I have read on here to improve battery on DL30, but so far, it's still pretty poor. I keep hearing about people getting excellent battery on DL30, so there has to be something I can do to be one of them.
Thanks in advance
EDIT: Honestly didn't realize I was posting this in Dev forum. So sorry. Please have mercy on me. Please move to General
You might as well just update to EB01, since that's now out, and DL30 is very likely to be abandoned very soon. Upgrading to EB01 might also 'fix' whatever battery issues you have.
My battery is not doing to well either. I can's use exchange because the email app runs at 100% all the time and it drops like 5% every few minutes. went to 70% in an hour.
I've had poor battery life on DL30 and Eb01 as well, I have services that constantly run on these builds that don't normally on others. Not sure what the deal is but battery life sucks

Upgraded to EB01 as first reply suggested. It appears the SnsService constantly restarting thing is not happening anymore, but my first impression is that battery life is still pretty poor. Decided to go with Superclean 2.0, too.
I'll have a better idea tomorrow using it a full day on a full charge. Plus, I did not wipe battery stats after installing EB01, so I'm planning on trying that tomorrow morning when the charge is 100%. We'll see what happens. But I can honestly say, I'm a little tempted to just go back to DJ05 or DL09. I had amazing battery life with both of those.
Try cycling both gps and data twice after reboot..that stopped the 100% system up time for me.
Anyone else's phone running extremely hot since the update? When I have it charging and streaming pandora it just sucks my battery. Before this update, I was able to do this without taking a hit on the battery.
I went to the sprint store yesterday and they tested my batter and it was good. The radio in particular gets extremely hot, put it in airplane mode for a few minutes and the phone cools off. I'm wondering if I should load a different kernel. Could that potentially help? I noticed most of the kernels are overclocked, which I don't really care about. All I want is something stable that gets decent battery life (6-8 hours) of heavy use and the ability to have it on the charger without draining the battery to 50% after I unplug it.
Anyone else seeing any issues with heat and poor battery life?

Download either Spare Parts or BatteryHistory from the market.
Open the battery stats and toggle the top drop down to sensor usage. See if any application has a high % of usage. If nothing with high usage, then toggle partial wake usage from the same top drop down and look for the same.
My OTA install is wonky with the Gallery. The moment I open it, it destroys the battery with sensor usage. Even if the app isn't open.

I'm using spare parts right now. I don't see how you can find the percentage of usage. Android system is using about 30% (guessing) under sensor usage. Under partial wake usage, android system is about 10%.
Nothing that throws up a red flag.
Just rooted/unlocked my Nexus 4, installed TWRP, and decided on going with LiquidSmooth because of the consensus that it was easier on the battery than other ROMs. While running stock, the only time my phone became warm was while playing an intensive game. I'm noticing now after installing LiquidSmooth that it's getting hot, to the point that I'm actually quite nervous about it being damaging.
At first I thought it was due to charging, but idle and charging in my car, off an a/c outlet, or my computer shows no increase in warmth. I noticed it happening again while laying in bed and listening to a podcast (using Podkicker). To rule it out being any audio source I started streaming music over wifi, but it's gone cool again.
In addition to the heat being generated, it appears to be draining my battery pretty heavily, 15 minutes of Podkicker brought it from 95% to 78%. Some of that is definitely due to the phone having very little information on the battery since it's just been flashed though.
Any thoughts or ideas as to why Podkicker would be causing it to overheat so badly now that I'm running LiquidSmooth?
I've enjoyed the ROM from what I've seen so far, but seeing as I've only invested a few hours into it I'm looking to hop into something else. If there are any suggestions for another ROM to try I'd be interested.
Edit: New discovery - it only happens when using the audio output?
I've been having similar problems, but they happen when I play online games on the phone. Kinda getting frustrating.
