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.
Sent from my SGS Vibrant.
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%

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?

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.

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 have two Arias, one freshly rooted with the rooted stock ROM and one running attn1's FR008 flashed straight from the freshly rooted state. The only additional app installed is BattStatt, so I can easily monitor battery state. One battery is new, with only a few cycles (over about a week) and one battery is older, purchased in August.
Over the next few nights I will be doing an experiment. Both phones will be on, same settings for GPS, WiFi, Data, and Bluetooth. They will only have the displays set on about every hour or so to check battery states. The following night, the test will be done again, with the batteries swapped. I will then run the test again with WiFi on, with intermittant connections due to my work environment.
I expect to update this thread after each night's experiment.
The first night is an exception, I'm comparing my normal ROM (loaded with apps, widgets, and running Tasker) My first night has been interesting...one running freshly rooted is still 100% after 1.5 hours. The FR008 with many apps is down to 89% (note that this is the older battery). Perhaps at the 4 hour mark, I shall swap them. It would be nice to do this with 2 new batteries, but I have what I have.
This is being done to lay rest to the claim that one ROM gives better battery life over another. Seems like it is going to be conclusive if the first night is any indication. Perhaps we'll see what app is the culprit? (Widgets??Tasker??)
Phone calls?
Interesting article regarding battery life
Interesting experiment !
Just FYI - an provocative article :
Your Battery Gauge Is Lying To You:
Everything You Need To Know About Bump Charging
And Inconsistent Battery Drain
No phone calls on either. Just to be fair, since one is without a sim card, both of them have data turned off.
At the 4 hour mark, the original rooted ROM is still at 100% and the FR008 with mucho is at 82%. I have swapped batteries.
This gave me an opportunity to race bootups. The stock ROM booted up and was usable before the FR008 (with UOT cooked startup bootup animation) even got to the dancing droid. Makes me want to undo that to see if that is slowing down the bootup.
I am eager to do this full swing with clean ROMs tomorrow. I shall make a backup of the FR008 ROM then go back to the aria_shipped_rooted_signed.zip
(found at http://forum.xda-developers.com/showthread.php?t=783508&highlight=Original+ROM). I will then flash FR008, adding only a widget for easy monitoring of battery levels, BattStatt.
This experiment is going to have to wait. Part 2 of last night's experiment indicated that my older battery drains fast in either device/ROM. The article linked in this thread is good reading. Thanks for that info.
My last Intruder was a Grumman A-6E.
Awesome idea
What a great idea - I hate the battery life on my Aria, and have tried multiple ROMs and multiple battery programs. I look forward to watching your progress with different settings and ongoing informational reports

I pretty much ran a similar test
I have two Aria phones - both the same age
one is stock 2.1
one is FR008
I set them both up the same - running HTC Sense -
I set the phones down (while I slept) for 8 hours
the stock phone drained 10%
the FR008 phone drained 43%
Did it twice
I know its not a 'real' test , but it does make you go hrmmmmmmmm.

You set the phone down for 8 hours and your phone drained 57% battery on idle for FR008? I find that very hard to believe because I have set my phone down over night and it drained 2% of my battery if even that. FR008 has shown the best battery life to me over the entire FR series. As of right now, my battery has been off charger for 6 hours, and Ive used the internet, wifi, and light texting with my battery at 100% still.
Edit: Im also using SetCPU...I dont know how much of a difference that would make, but there should be a difference. Try using SetCPU
FR008 is a battery drainer from hell. I just accept it.
SetCPU slows down my phone to epic proportions--no thanks.

It wasnt just one night - I tested this for 3 nights straight before I made this post -

Here is a note :

I said I have been off the charger for 6 hours. Not necessarily using the phone for 6 hours. I browsed the web for around half an hour and sent about 30 texts since Ive been off the charger. I just dont see how its possible for your phone to drain 57% while youre not using it. What happens when you start using it?

Before I left the house to go to work, my 10.1 Tab (Google I/O Limited Edition, rooted with 3.1) was at around 80%. I get home 9 hours later and the battery is completely drained. I plugged it in to the charger and turned it back on to see the battery at 1%. That just doesn't seem right to me. I can usually go about 2 days without putting it on the charger.
I've attached an image of the Battery Use graph, you can see it just drops like a cliff for no apparent reason. Has this happened to anybody else? Also, I just noticed that the time it was off (approximately 9 hours) is missing from the graph, so it only shows just under 5 hours.
I had the same issue last night. It had ~40% battery left when I went to sleep last night and this morning it wouldn't turn on, so I plugged in the charger and found the battery drained completely.
Interesting that it happened for you the same night. For me, it seemed to have happened around 5-6pm Pacific time on June 23. I don't know the exact time because I didn't have it with me at the time.
Happened the same to me a couple of weeks ago.
Battery was at 40% and overnight went to 0% and the tablet turned off.
Very weird
Came home to find mine with the screen on but completely black so you could BARELY tell it was on. Had to reboot as it wouldn't respond. When it did I only had 20% charge. I had unplugged it about 5 hrs earlier and left it with about 95% charge. Only happened once though so I haven't worried too much, maybe a similar issue though

If I had to hazard a guess.. it would probably have been a runaway process in the background somewhere that totally drained the battery. If it was the battery itself losing a charge like that, I would be worried.... When batteries discharge like that for no reason, they can actually explode... (it is rare, but possible..not trying to cause a panic).

Wouldn't a runaway process drain the battery slowly over time? This seems to have happened instantly.
I really hope i dont find mine doing this... If I watched a laptop do it I would say the battery was shot. Now that its been charged does it hold a charge just as good as it was prior?

Hi, I've had my Play for about a week now and absolutely love it. The only thing I don't get about it is it's weird battery usage.. it seems to charge slower than it uses for one thing, and the usage seems kind of random.
Last night I went to bed with about 70% battery usage. This morning I woke up and my phone was off. I tried turning it on while charging but it didnt work (not even a charging indicator), I took out the battery and put it back in which got it working. Once it booted I checked the battery usage and it showed it basically went from 70% to 0% at once..
Also when checking what processes used the battery it seems off.. Camera 15% while I hardly used it, Keypad 5% seems weird as well.
Anyone know what's going on? Is this a common thing with the Play or is my device possibly malfunctioning?
Thanks
Your usage seems nothing like mine. Mine says standby, display and wifi take the most and doesn't even show keypad. And my battery draining is always consistent, it doesn't fluctuate like yours did.

@Naatan I've sent my device to service for the second time now. First time it was something different than this, but since i got it back last monday it has acted like you posted, not exactly the same as you describe but close. My phone also turns of during the night at some point, first i thought it was drained. Had to pull the battery first and then leave it in the charger untill the charging symbol showed before i could boot again and when booted up the lockscreen showed 35% one morning and 62% another morning. So my phone is not draining but acting weird. Even when i turn it off i have to pull the battery to turn it on again. My phone is updated to the newest firmware 4.0.A.2.368 - 2.3.3.
As i said it's at a service place right now (they broke my volume button last time they fixed it, so i had to go back) and when i get it back from repair i will downgrade to 2.3.2 and run it for a week and see if the same thing happens and then i will update to newest for a week and see what happens. I think it's a bug in the new update, randomly hitting devices as they are not all alike as in the hardware behaves a little different from device to device, hence when oc'ing you have to do it a little at a time cuz one clock works perfectly on one device but messes with another.
Will report my findings.

I have CM7.1 on my MT4G. Over the past week or so, my battery has been dying after 2-3 minutes of use. I'll get a full charge, take it off the charger, use any app(Angry Birds, Gtalk, text messaging...) and the phone will shut itself off after just a couple minutes of use. When I turn it back on, it says 2%-3%. It then shuts itself off again, I plug it in and turn it on...says anything from 3% to 90%.
I've always ran the battery down and charged to full. Is my battery kaput? Is there a way to fix this?

Most likely.. take out the battery and inspect for leaks(might be very small discharge you might not see it clearly leak can and will damage your phone)..let it die completely, and let it stay off, charge it till the green light comes on, reboot into recovery, clear battery stats, reboot and see how long it last, also change your brightness, and other settings that might be consuming battery use..if none of these helps.. just buy another battery.
Sounds like your battery is screwed. Just buy a oem battery or get a mugen power 1650mAh

My issues aren't quite that bad, but after I upgraded to CM7.1 from 7.0, by battery has been terrible. 15-20m of phone calls over BT takes ~20% of the battery. 15m on Angry Birds chewed up ~40% of the battery. I downloaded the latest nightly (252) and will see what happens.
Try a dif battery and see if it does the same thing. So you can rule things out

Mines also been horrible since I went from CM 7.0 to CM 7.1. Not sure whats up but it dies in like 6 hours on standby. the battery use app shows that most of the battery usage is by "Cell Standby". So effectively, doing 'nothing' is eating up the battery?
~Phil
I guess I'm not having the problem you guys are having with battery drain. Granted I didnt use my phone that heavily, but still sitting at 60% after 10 hours. But if your battery is dead after 3 minutes something is seriously wrong, I agree and try a new battery.

You need to calibrate the battery after changing ROM's. Download a battery calibrator from the market. (Don't pay for one. There are like 10 free ones)
Charge the phone fully overnight. Calibrate it in the morning.
Give it a few days to gather new battery data, and then enjoy getting a full day's use from the phone.
Update
So, it's gonna have to be the battery. Recalibrated, no good. Tried a few different ROMs from CM7 nightlies to MIUI, no good.
Waiting for the new battery to get here to be sure.
Thanks for all of the help and advice!
same problem here
hello there, i got 2 mytouch 4g both running the same rom (virtuous unity 2.39) one of them has eaten 2 batteries that i bought thinking that the batteries were somehow broken or damaged... i came across this thread, read the reply recomending battery calibrator when i reached for my phone (that i left sitting on my drawer waiting for a new batt AGAIN) to give it a try and to my surprise it was still on and i has been on for 2 days 11hours and the fricking battery was at 97% before that it started to turn off-discharge so i put the thing on airplane mode and there it was till now... dunno why or what but i think it has something to do with the radio/network... hope we find a cure for this
I've been having this same issue, and I was wondering if replacing the battery fixed the issue? Thanks.
