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

Battery life after Jelly Bean Update

how was your battery life after update . my was suck drain very fast

I don't know how most people got better battery life, but mine worse, not extreme, but noticeable worse.
Android system and Android OS takes second and third place, which on ICS I barely see their place on top of battery usage.

Seems the same for me...at first after updating battery life was terrible..but after a few charges and reboots it seems to be getting better.

Download an app from the play store called "CPU Stats" and see if the CPU is under serious load when you're not doing anything. If it is, you may have the same issue I had which was that the media scanner was getting stuck in folders that had a lot of files in them. My idle cpu utilization now hovers between 8-30% on core 1 and core 2 stays sleep for the most part.

If you're rooted, look in system/bin on the root directory and see if you have a file named gsiff.daemon (also do the same for qosmgr) If so, add .bak to the end of it.
this will kill the high android usage!

I offloaded my Titanium Backup folder to my PC & deleted it from my phone plus made sure to get rid of any corrupted pictures (aimed at the 0 bytes ones). So not only is my battery life better, but the performance is also much better because the CPU(s) aren't really doing anything until I actually use the phone. Note that this is an issue I've only had w/ Touchwiz Jellybean and never had it with CM10 or any AOSP based rom. This is a bug that Samsung/Google really needs to get on top of because I'm sure that a lot of people are having this problem and don't know how to fix it.

My battery life has been amazing
This was after the weekend. Friday Morning I charged it and then I was off I went to work. After I went to a party didn't charge my phone. Woke up in some girls room. Still surprised I had more than 50%. I didn't go home that day and everyone had an iphone so I couldn't charge my baby. Wake up go home and I had this much and I was like wow holy sh**.
Stats: I had a little over an hour of talk time and a little under 2 hours of screen time.
Yeah I know why is battery life good if you don't use the phone but dude seriously I had a GS2 and drainage on standby was so bad. I like that they improved standby battery drainage this was beautiful. I have the latest Stock Jelly Bean. Rooted, debloated myself with stock Kernel. Might add a new Kernel but don't really need to this is just great.

I was having this exact issue and fixed mine by copying my external SD card contents onto my desktop and then reformatting my sd card. After that I just transfered my old pictures and videos back to my card.
For people who are having poor battery life, the best thing you can do to help others help you is post a screen shot or at least write down what is using your battery and how long you have screen on time. When I was having my media issue it was obvious when looking at the battery usage since my cpu was constantly awake. Just saying "i have poor battery life" really doesn't explain much at all.

That would explain things... I had my media scanner get stuck and take down my battery a couple of days ago... after a reboot though it was much better... Though I should have let this run longer on battery just to see how long it would run.

Ok so since the JB update it seems my battery has been draining a bit faster. I've tried turning off sync and all the other normal stuff but it doesn't seem to help. Here are my stats and the slight lapse on the time line was when I was in CWM doing a nandroid backup.

I don't think that you can compare yours since you did a backup, that always drains the battery more than normal use would.

Well all I can say is its normally like that. I pull my phone off the charger at 7 am and by 4pm its usually at 10% with maybe an hour of on screen time. I'm just trying to figure out why it dies so much quicker than what most people are posting here. I try to keep everything closed and off and I've frozen all the bloatware.

[Q] Awful Battery, Not Sure if ROM or Phone

Hey guys, I have a little bit of a question for ya.
Now my phone's battery life has been awful lately. Certainly not what it was when I first got the phone. I'm lucky if I can get 6 hours mostly on stand by.

Theres what my battery usage is looking like right now, as you can see, its a steady decrease for the most part, but not a steady amount of use on my end.
I use Advanced Task Killer religiously, and even have it set to autokill. The weird thing is, my phone will get insanely hot sometimes while I'm not using it, I'll check ATK, nothing out of the ordinary, check running apps, nothing out of the ordinary, and if there is always kill it.
Right now I am running a CM10 nightly that is a few months old. Do you guys think that could be the case? I'm really not sure what else to do.
Any help would be greatly appreciated!

Get rid of the task killer. They are useless and actually make your battery work harder. I'm not sure, but it looks like you don't have a solid, steady mobile signal. It looks like it goes in and out. That kills battery life.

Thanks for the replies. I got rid of ATK. I had a slight feeling it could be that because its on 24/7 monitoring apps, but I guess I just didn't wanna believe it lol. I got GSAM battery and I'm gonna run that for a few hours, see what's going on, but hopefully things will be all fixed. Thanks for the help!

#1 problem: Verizon GNex, the battery life is dreadful. Screen on time is lucky to be half the GSM version.
#2 problem: Verizon GNex. There's a factory flaw in many of them that leads to the phone getting extremely hot at the top and having atrocious battery life. Only permanent solution is sending it to Samsung to get it fixed. The temp solution that's worked for me is draining the battery dead and recharging it with the phone off. Don't know why it's worked but it keeps the heat away for about a month or two for me.
#3 problem: (you guessed it) Verizon GNex. In areas with weak or no LTE the radio will endlessly consume. Try turning the radio to CDMA only and see if you get better life. Just pop it back on to LTE when you're using it.
Yeah... these are just a couple of the reasons why there is no Verizon Nexus 4...

I agree with this. Task killers are really not necessary in Android. Android manages applications in RAM just fine and by removing them from run you are making your system even slower in loading them to the primary memory and thus can lead to a decrease in battery life.

[Q] Slowly Decreasing Battery Life

I updated to 4.1.2 about 3 weeks ago or so. Not sure exactly. And the battery seemed to be just fine then. But slowly over these weeks, especially the last 4 days or so, it seems to be decreasing. I used to be able to go a whole day easy. And still have 45-50% left. And that would continue into the next day. Sometimes I would get 2 whole days and sitll have about 15% and then decide to charge it back.
Now, I can barely get a full day. And when I don't charge the phone at night, the battery charge decreases quite rapidly. Sometimes 15% or so with no usage at all overnight. It used to maybe move 3% at the most overnight with no usage.
My settings are the same. My usage is the same. I see time without signal is 2%. Nothing extremely high there.
Is this just one of the downside of 4.1.2 or is there something else happening that I'm not picking up on?
I didn't want this to really turn into what apps are out there to make the life better because I hate jumping through all those hoops and settings to get the most. I know this phone has the potential for 2 days of moderate use out the box because that is what I used to get. Seeing if I could get back to that state.
I was told to go into Wifi settings and change the setting not stay on while the phone is sleeping. Did not help at all. Per this video:
http://www.youtube.com/watch?v=mInF-ZRX5bs
Did that last night. Charged it 97% and went to sleep. Slept for 5 and a half hours. Did not touch the phone at all. Woke up and it's at 82% this morning. Here's the screenshot of the battery stats:

Glad it's not just me then. Have you found anyway to make it a little better?

Well if you don't need to wanted at night, then what I do is put it in airplane mode and take off when waking up.
If you still get wake locks, check to see which ones they are off a wake lock app.
Also before I put into stand by, I exit all apps, also restart phone with airplane mode on. Doing this I haven't lost any battery life at all and seems to help throughout the day as well
Currently 60% right now and over 3 hours on-screen time and 16 hours.
Doing much better if I don't do what I have been doing.
Also make sure all GPS location settings are off. Huge battery drain for me.

Yeah I know airplane mode will work but I receive texts late at night sometimes and those would not come through. Before this update, I never had a problem. I never had to make sure apps were closed and all this other stuff. It just never drained on me at all. When I first had the phone, I used to have to try very hard to drain the battery to zero so I could let the phone die and then get a full charge. The battery life used to be very great. Now, not so much.
And I have no idea why Slacker is being used like that. I haven't used that app in 3 weeks. And I don't see any settings that would cause it to being used in the background when I'm clearly not using it.
Yes I never have GPS on until I need it for navigation purposes. I'm hoping Key Lime Pie fixes this or we get another minor update before that.

Same here owned it since december...great battery and after update it went down the drain (especially losing 15-20% overnight with just about everything turned off. I would usually let it get down to 10-15% and then charge. Well eventually my phone would only charge "when it wanted too" so I got a replacement, updated to 4.1.2 and battery lifes has been great.
As far as not doing full cycles or not...ive looked and looked and everyone says diff. Some experts argue it's good to let ot drain till about 5% and then charge And other experts say charge often and not let it below x percentage. Soooo confused on the topic, so in the end to each their own I guess lol
