Incredible Battery Issue!!

I put the leaked 2.2 update onto my phone and it has been great. I have only had one issue with it thus far. Starting yesterday my battery life plummeted drastically out of the blue. It seems like it came out of thin air. There is no water damage or anything. I am avoiding doing a data reset. Does any one have any other suggestions?

Is your phone staying constantly awake? Is there an App causing it stay running? Are all of your apps up to date?
I've been on a 2.2 ROM for over a month and I have great battery life, even with my overclocked kernel.

I use Advanced Task Killer and my phone goes to sleep after 1 min. 2.2 Worked perfect with great bettery life for about 2 weeks. But last night everything went downhill. It maybe an App i downloaded? but i looked in my apps and things seemed to look normal.

Do you have the task killer automatically set to kill after a certain amount of time? If you do you may be killing processes only to have them be restarted right away by android system, then killed again, restarts...and so on. That will kill your battery like crazy! To be honest, try going 24 hours without your task killer and see what happens, I noticed an improvement. The way android manages it's processes there is no need for a 3rd party task killer. Also try the KingzKernel's they are fantastic with battery life.

K, regardless, uninstall it for 1 day. U may notice a decrease in it benchmarks but ur actual performance will not change. I was a skeptic too, just give it a shot.

I'm having the exact same issue. I flashed the virtuous 2.2 rom. The battery is dropping waaay too fast. This needs to be figured out

I'm having the exact same issue. I just flashed SkyRaider 2.5.2 the other night and Radio 2.15.
The problem I'm having is that my charge is taking almost 4-5 hours to charge when it use to only take a couple hours. Also, my battery is draining QUICK.
I just clocked it and I went from 100% battery after a 12-hour charge to 93% in about five minutes.
PLEASE, someone help with this issue.

I never had any issues with the original 7/28 leak (or whatever the date was), and once having the bugs worked out, never bothered with the 8/1 leak. I did the 8/26 leak as soon as it came out and was plagued with charge times exceeding my 7-hour per day sleep schedule, and battery life that would drop drastically with the screen off. I literally went from 40% to 5% in a matter of two hours with my phone sitting on my desk, screen off. I used nandroid restore to go back to the 7/28 leak i had backed up. I'm not sure where the bug is, but I hope Verizon/HTC release this update soon, so the OTHER 95% of Incredible owners can start *****ing too. Then maybe something will get done.

I tried bump charging this morning and it made no difference whatsoever. Withing 2 hours I'm at 35%. No Facebook syncing or really anything syncing for that matter... Just a crappy battery issue. Tried different Kernels and no difference which leads me to believe it may be Froyo or the Rom I'm using which is the virtuous Rom but that doesn't make sense....

I'm surprised this has not been addressed on a much larger scale within the XDA community. There is no way anyone could enjoy their Dinc with that much battery drain.
I am using the 3500 mAh battery and with stock phone and no root I was able to charge my phone in about an hour and could get nearly 2 days with heavy usage. Now I'm not sure I can even get 12 hours, but I haven't fully tested that theory yet.
My plan today is to do a full charge (Which will be done in a matter of minutes) and then I am going to do some clocking to see exactly how long it takes to discharge.
Regardless, why is this not a major concern in the community? I only see a few posts relating to it.

Ok, so I think this has been brought up before.
When my phone is at a complete IDLE (89%), my CPU is rocking out at 900+MHz.... I think this is what is causing my severe battery drain. Can any developers respond to this or can someone else advise? My sister who uses her stock phone with no root, etc is idling between 245MHz and 320MHz.
My battery is dropping way to quick and this has to be the answer. Please help. Thanks!

Thing is...
If you're on this forum, you're probably a constant tweeker. The so called "battery issue" is all over the place depending on who you talk to. I wrote "Making Your Droid's Battery Incredible" over at my website, but essentially you need to figure this out yourself. Battery usage depends on so many things like the programs you run, the kernel you're using, and the battery you have (and the condition of said battery). If there were a uniform problem, it would be much easier to identify.
Oh, and if you're humming along at 900mhz while idle, try SetCPU.

Battery Life dreadful after ITL41F

Hi Everyone,
I was wondering whether anybody else has experienced this side effect of the ITL41F update? My battery life has been really really good, much better than that of my HD7. I was really chuffed with it. Along comes the ITL41F update, and since then the battery will drain itself on standby. Nothing has changed on my phone. I have not installed any new apps or made any settings changes (such as sync frequency, etc). So the only difference is the ITL41F update.
To give you an idea, If I charge the phone in the late afternoon, and then pretty much leave it alone, by the morning it will have gone down to 15% battery or less. This morning I plugged it in again, and now it's down to 50%. And I only sent a single txt message and didn't do anything else on the phone. This is properly rubbish.
Anybody know where I can report this bug to Google/Samsung?

You have a lot of awake time without your screen been on which seems a little strange.

I would say your mobile signal is using up a lot battery. when it is yellow that means its weak, and grey means no signal. Since this is the main 2 colours on your chart I would say this would be the main reason for your battery drain

How would someone go about improving that? My mobile connection is mostly yellow as well. Could APN settings help that? Or would I have to go about flashing a different modem and all that

Are you seriously asking that question?
You improve your mobile signal but getting your network provider to install another mast, or switch to a different network with better coverage in your area.
If you could improve signal with APN settings or flashing a different radio it would be done like that from the factory!

WEll, I have a LG Optimus One and use franco kernel with it, and am soon buying a GN because he develops for it too, SO:
FLASH FRANCO KERNEL!
DOnate him a beer before and ten after the WOW-experience you'll get when you realise 4 days later that your battery is only 10% becuase of the popup.
And now read my words again.
It's the best option!

Your phone was awake for more than 50% of the time. If you really didn't use it, there's most likely a rogue app which is preventing phone from going into deep sleep.
Use an app like System panel to locate the culprit.

nevermind - delete me

Thanks for the fast replies guys, it's much appreciated! =)
What I find puzzling is that absolutely NOTHING has changed on the phone, apart from the update. So if there was a rogue app that was consuming the battery, it should have exhibited that behaviour before the update, right?
I will check with system monitor though, to see if I can spot something. The strange thing I noticed is that the OS is consuming *more* battery than most other functions. Even on standby.... weird!

After finally getting the patch I can't say the battery has been worse. In fact it seems to be better. Although I think that is down to the fact I've been through a few charge cycles now.

click on android OS, and check out the awake and CPU times. The cpu time should be a fractions of the time awake.
example, my phone has been on this charge for 22 hours (still 36% battery left.. didn't use it too much this charge). the leading battery drain is screen at 51% (2.5 hours awake time), and the 2nd leading item is Android OS which has the following:
CPU Total - 18m 53s
Keep Awake - 4h 46m 9s
I'm just curious on why your CPU total was in relation to the awake time by Android OS.

Mines great.

its funny how many similar theads appear everytime a phone gets updated. And most of them all go down to user error.
Just saying. my Gnex is fine after 11F update, OP should probably do a wipe

Guys, I'm not ruling out 'user error', but at this moment in time I cannot see what I could have possibly done to cause it. I have purchased System Panel on the Market and I'm running it in monitoring mode to see if it can shed some light on the issue. Strangely, 'Cut the Rope' and 'Exchange' are running constantly and as a service. Not necessarily consuming CPU while the phone is asleep though. Just though it would be strange for a game to be running as a service? Must be a reason for it....

Ask the developper of "Cut the Rope" why does it need to run that way. Exchange is run as a service because you probably need it.
Anyways, you can try a clean flash with stock ITL41F. But i'd say apps are to blame

Did you factory reset after the update? If not I realize it sucks to do, but.....that's the road I would venture down.....have yet to own a Samsung that it wasn't almost mandatory to do. Always a battery and sleep issue.

Bad battery?

I have had some issues where my phone won't wake up so I have to pull the battery and when it reboots the battery drops like 20%. Is this a bad battery or what causes this?
Sent from my SPH-D710 using XDA Premium App

what rom are you running? if i remember correctly there was an issue with one of the roms but i cant remember. but I do remember it being an older rom that did that.
as for the batt. % i get that all the time even when i reboot..tho i get a bigger drop in % when the batter is lower.. like if i was at 50% batt power.. reboot then i would be like at 20% batt. power.. but it would stay at 20% for a really long time till it caught up with it. and sometimes the batter % would rise up a bit. but eventually start to go down again.
But maybe I have a bad battery also.. so im not sure...lol

I had the exact same problem my phone would constantly reboot and shut itself off then I would lose half my battery % I thought it was the battery too so I returned it to stock and took it to sprint they looked at the phone for 2 hours and said there was absolutely nothing wrong with it or the battery. So I took it home and re rooted using Qbking77's latest method the one that does not give you the yellow triangle and I have not had one reboot or sleep of death since and the phone just runs soo much better now so I think it was a bad root for me. I would try re rooting with the latest method and see what that does for you. Also ya out of curiosity what rom are you using because I have heard similar stories from people running the ICS leaks.

I'm running caulk's fc07 1.1 with the repacked kernal. It happened to me before on GB while also running caulk's rom but it only a few times. It seems to happen more now. Here is a screen of my battery
Sent from my SPH-D710 using XDA Premium App

I believe this would happen more in most recent ROMs because everyone is focusing how fast we can run it or how long we can use it. In either case, there are lots of tweaks and mechanism to make it fast and last long.
For the battery life, there is some background process monitoring unnecessary processes and kills those or tweaks to less frequently monitor the status. So, if the process which is related to battery life is killed, next time when it wake up, it may detect the different life time based on current Voltage or mA. I'm not an expert in this area but it's highly possible scenario. Tweaking the system brings lots of good things to us but in the other side, there could be some
side effect.
If you want to verify this theory, you can just compare the non tweaked rom versus tweaked Rom.
Be sure that you don't run any battery saver apps on non tweaked rom to measure it correctly.
Attached is my last screenshot yesterday after I removed the battery saver app. Currently I'm using Calk's Stock Rom FC07 (non tweaked version). Based on my test, the battery last longer than when battery save app installed and running.

Cool I didn't know that would be an issue. Well I'll try that thanks for help

Also a note... with my experience anything to do with 3g service... I can kiss my batter life goodbye... if im at 100% battery life.. and i have 3g on... it will last around 5 hours and its dead

Battery dead overnight.

So, I had about 50% juice when I went to bed last night. Woke up to see phone dead. Had to plug in charger to start it as battery was fully drained.
So what causes such sudden battery drop?

It seriously looks like some apps have been doing some heavy tasks while youre sleeping..
Check with your nearest dealer. Then contact samsung if you think your battery is faulty

Battery doesnt seem faulty at such an early stage.
Best solution. Download BetterBatteryStats and check out what is draining your battery
Its the solution i would do with myself

I dont even have much apps installed yet. & battery life so far was really good until this morning. Seems quite stange. Has it happened to anyone else?

I don't think that could have been any apps to deplete the battery that quickly. I mean, that literally did a nose dive. Ever heard of Ghosts?!? DunDunDunnnnn

Does battery reset itself somehow?

Yes, an app or some apps drained your battery No other solution possible mate . As mentioned before install BetterBattery Stats and cpu spy and check for unusal app behavior.

The thing that surprises me is that on the steep drop, the green border-line is missing. It doesn't look like drain; it looks more a short circuit...

Its actually not a drain. Its a sudden cut off.

In your case, don't bother with better battery stats or any other that other crap people are suggesting. I don't think the majority of the people who read your post bothered to look at the attached image (or didn't understand it.)
During the time that your battery dropped off, android wasn't even active (as no battery stats were logged.) That drop-off looks to me like some type of system crash or something rebooted your phone into recovery (or download) mode and left it there until the battery died (causing a power down.)
I can't tell you WHY that happened, but I can't think of anything "normal" that would cause it. I used to see something similar when I was doing kernel work on a specific samsung tablet if the user had one of the so-called supercharger scripts installed. In that case, the kernel would panic (wifi bug) and the script had re-written the kernel parameters to cause an infinite loop instead of letting the kernel panic reboot the device. The result was that the device would get warm and drain the battery until there was no more power.
Recovery meant charging the device first and upon finally getting it to boot, the battery page would look similar to yours.
Another possibility is that your phone hit what it THOUGHT it was around 46%, but the battery stopped giving juice.
In your shoes, I'd do something I usually tell other people never to do: Purposely run your battery down below 40% to make sure the same thing doesn't happen. (If it does, consider restoring your phone to stock, testing again, and possibily calling Samsung.)
Good luck

Thanks for the prompt reply.
Meanwhile battery life was normal throughout the day. I will follow what u suggested n if it acts weird again, I'll have to go to samsung i guess.

Battery drain during standby.

It used to be that with the screen off and the phone on idle with the screen off, I would lose maybe 2% per hour. This morning, my battery quickly dropped to 50% with some phone call but very light use. So I charged it back up to 80%. For the last hour, it dropped about 9% with the screen completely off and I had cleared the memory prior to that. That is unusually high since the phone is sitting in one place in an area that has good 4g and 3g.
How is your standby battery drain? I am on LJC stock rooted.
Edit: reboot phone and now it is better. Loosing 6% in 2 hours of standby. Much better.

Glad a reboot helped. I'd recommend rebooting every day. I usually do it first thing in the morning and before going to bed.
My battery life on LJC rooted was fantastic. Never had a phone like this. My EVO3D with 3300 extended battery was good, but still not as good as the note2.

I experienced a really weird battery drain a few weeks ago but cannot replicate it. However it dropped from 100% to 42% in 2 hours time. Pulled battery recharged it and nothing since. But I usually get 16+ hours a day with extreme usage. I am talking 5 hours of netflix and some pandora and games. On my weekend when I dont use the phone much I get 48 hours usually.

Which app is that? I've been looking for something to view battery current, many I used on HTC phones don't work on Samsung.
Does that app also have a better understanding of what apps are causing battery drain? I'm tired of seeing "Android OS" and not knowing EXACTLY what it is...Might help me diagnose my Fiance's E4GT (GS2) with "Android OS" as the main culprit at 67%...
