No, not normal. I get home with like 55-60% battery left with
12 hours standby
1-1.5 hours calls
1-1.5 hours with activities that keep screen on like texting, mails, etc
i am on the ROM in my signature.

ok is there anyway to get reduce the battery drain without changing roms if not whats the best rom for battery life??

Try using a kernel that supports UV and setting slightly reduced voltages. I am using GB's 1280 kernel, and capped the speed at 1000. And reduced the voltages slightly.
Others would be normal things like switching to EDGE, lowering brightness levels, setting wifi to "turn off when screen off", etc.

what does UV mean sorry im a newb :/ and how do u install a different kernel

UV = Under volting

1. Load the kernel in my signature (attached to this post)
2. Install the voltage control app (attached to this post)
3. Start the voltage app and set the voltages and cap at the levels based on the pic in this thread.
WARNING: Voltage levels depend on phone to phone. I would suggest starting from low values. Take off 50 from the values I have posted in the pic and use them. If u feel it is ok, then add another 25. Take it slowly checking if the reduced voltages are freezing up ur phone.
I would recommend u starting with these values: 75 75 50 25 25 0 from bottom to top.

Ok thanks diablo I will test this out tomorrow and report back

Sounds like a good old battery recalibrate is in order:
1. Connect the phone to the charger with the phone powered on, and allow the phone to charge until it shows 100%
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the battery indicator shows 100% (you can use vol-up/vol-down to make the indicator come back up when the screen goes to sleep).
4. Disconnect the phone from the charger and power it on.
5. Once the phone is powered completely on, power it off again and reconnect it to the charger until the battery indicator shows 100%.
6. Disconnect the phone, power it on, and use it.
I did this a couple days ago, plus wiped stats, and as of right now, I am showing 20% after 30 hours. No joke.
Running Cognition 3.04,

juice defender is amazing!! it helped my battery so much!!! thanks a lot!!!

Try searching google / this forum for a post of resetting battery stats, i need to do that also since my battery life isnt all that good either, especially how im running 3.04 cog and everyone says batt. life is amazing. SO if anyone can link to battery reset post that would be amazing.

Ironically, JuiceDefender killed my phone *much* faster than with me manually enabling and disabling my data connection.
IMO, JuiceDefender does nothing that you can't do yourself, the problem is, is that it constantly has to check apps to see if any are enabled to toggle your data connection.

I am just saying

I actually use my phone and I am getting these results

I have a very similar question. My problem is, on custom roms (I've tried Assonance, Serendipity, and another), my battery drains 1%/hour. This is even after a fresh install; nothing is running in the background. When I look into my battery info, it says wifi is doing the draining. I keep hearing people saying their battery life is amazing after flashing custom roms, but I'm getting the complete opposite. Am I forgetting something?
Without custom roms or anything, and using a rooted/lag-fixed (not sure this makes any diff anyway) setup, I lose somewhere between 2-3% battery per hour on standby. I don't even use juicedefender. I really love what they're doing with these custom roms, but the wifi on standby just rapes my battery.

ICS update Battery Issues

Alright so like many other people on this and other forums, I updated to ics 4.0.3 two days ago and been experiencing battery issues since. But my battery issue is a bit different from what I've read about. My note has no problem going into deep sleep, when i go sleep and wake up deep sleep is at 98-99% and my battery drains about 1%. But when I turn on my phone and start using it no matter what I do, the battery drains about 1% every 3-5 minutes.
Phone settings:
- I always have my brightness at 0 and have screen filter on to make it even less bright(even though battery drains about the same with or without this on) (batter settings still show that screen is taking up most of the battery)
- With wifi on or off battery drains just as fast.
- I havnt started my new data plan yet so im always on airplane mode( battery drains the same with this on or off)
- My note was never rooted
- I basicly have no widgets on anymore because i deleted most of them but doesnt help battery life.
- With power savings on or off battery still drains the same amount
- The only apps i have installed after ics are ones from googe play(netflix, chrome, and other simple apps)/ i deleted my emulators and other apps that iv'e downloaded and installed
Can anyone please help me with this issue

bump

You are on Stock ICS ? Go to Settings>Battery And Post the Screenshot Here. It will help us to determine the exact situation..

Sorry I'm new im guessing stock ics means official release from kies, then yes. I dont know how useful these battery ss will be because a lot of the time im either idle or charging.

Did you perform a hard reset on your device after the update?
if not, then see if you can try it and get back again with your screenshots.. don't forget to do some re-calibration also on your battery. This works on my end before. Not sure if it works on yours, but hey.. there's no harm in trying right? just give it a shot bud...
Cheers!

Turn off the sync. Kill Background applications and See if it works for you...
Also download Battery Calibration from play store... Open it when its fully charged and start calibration... Let your phone battery fully drained and then charge it again to full without pauses...

I have sync accounts off and i only have my gmail account in the options to turn it on unless you mean something else.
I'm not really sure how to kill background applications is it the cashed applications? because ive tried killing running + cashed.
I just installed battery calibration and it says i must root my phone 1st =/

Wtf are you trying to brick op's phone? You should get a warning..
Op never ever ever ever ever ever do a factory reset from ANY ics stock kernel.. It will get your phone bricked.. Or maybe but just maybe not? Anyways will you take the chance?
I was on 4.0.3 stock and yeah the battery it's horrible.. Don't know why the phone barely goes deep sleep.. Check this with cpu spy free app from market
Since the phone upgraded itself to 4.0.4 I have been able to run 14 hours with 5 hours screen and the phone its always on deep sleep
Sent from my GT-N7000 using xda premium

yea i knew theres a huge risk involved =/ , is there anyway i can update to 4.0.4 because it's not showing up on kies

Yeah following the several guides around.. They all lead you to download 4.0.4 and a gingerbread rom from Sammobile, downgrading your phone to gingerbread by flashing it via odin and then flashing ics 4.0.4 via odin also .. So go ahead and read some..

Check Android Development Section...

cpuspy and betterbatterystats to check partial wakelocks and whats keeping phone awake. A gazilion threads on that. read them. You need these as Samsungs analytical view state nothing usefull, they need to fire the designer of that.
Next to this I see lot of screen on time, how much time roughly is that in total, you are actually using device?
Sent from my GT-N7000 using Tapatalk 2

my phone doesn't have the deep sleep problem people have. my on screen time is about 6 hours before it drains completely and by on screen time it could be on the home screen with no wifi/net and no apps running with just the screen on, and the battery would still go down 1% every 3-5 min

So ics 4.0.4 came out for the UK version of note so i updated via kies. This didnt fix battery life at all, in addition iit came with another bug where my phone gets hot and drains battery when turn off the screen after playing any media file....So my question now is can i root 4.0.4 if i have the Emmc bug?

[Q] Weird "battery drain" when lightly using the phone

Hello !
I just bought my P880 two days ago and everything is great except one thing: battery drain. It is not occouring in background when phone is in Deep sleep, it doesn't lose charge while it's sleeping, but when I just unlock it/start using it, it just starts draining.
I have rooted it, and unrooted using SuperSU. The thing is I haven't experienced that kind of drain yesterday, it was working fine except drain caused by bad signal (badly inserted SIM).
Usage by Android System is at 50% over 5 hours, Screen is at 9%. Awake graphs are the same as Screen on graphs- no wakelocks.
I have these apps installed:
Prey Anti Theft
Skype (not running)
Adobe Reader
SoundHound
Disco Light
QR Droid
Sygic (not running)
X-plore
SwiftKey 3 keyboard
WiFi, GPS, Data, everything turned off except mobile signal
Running Internation version with Android 4.0.3, Kernel 2.6.39.4-00001-g0f9182c
Mobile network type is EDGE:2 with mobile signal -70dBm
I'm first time android user and this is my first problem so I tried to include as much info as possible.
Thanks in advance

I see 2 mayor issues, first is the android deft app, it may be running and trying to sync but bcz the data is off it will try to connect foreva.
Also, edge is (in other words) ROAMING and this forces the antenna to use more power to get signal from another provider, it get worst if you have a phone with sim card.

Thanks for pointing that out, but I have disabled every sync and I have set phone to 2G mode only, the reason is that UMTS signal was low and was draining battery even more.
I am only losing sharge when just doing random things on phone, even if that means only adding/removing widgets/apps on main screen with WiFi off.

Then you must try the Deodexed version of v10f, removing the bloatware with the script in the same thread.
The issue may be some lg apps that are running in the background so doing this will have 6 hours in standby time with 100% still, like me (if I turn all radios off ).

I have just woken up, while sleeping (9h) phone was awake for about 50%, no wakelocks but there were 30 alarms from Android/Google maps ans 29 alarms from com.google.android.gsf
Hope this helps.
I may try custom ROMs if nothing else works.
While typing this message I have lost 7%.

Similar state here as the OP. Got the phone two days ago.
All is good, it rooted OK, Directory Bind works fine, phone runs like hell (about 10 times faster than my old Galaxy S) BUT it drains battery like a genuine power guzzler.
Ok I get that according to the performance you get, it comes with an accordingly high power draw, so I don't ***** about it, I just want to know if this is normal. I mean I played 2 hours and 15 minutes of Sprinkle and the battery died, starting from a full charge. Screen was set at 50%.
GPS is off, Bluetooth is off, no 3G mobile network and screen is at 50% brightness as I said. There's an NFC icon on the notification bar next to the battery icon, which I am not sure if it should be there.
Here are a couple of shots from the battery section of the phone and from Battery monitor widget if these help.

Please note that as the OP said, the phone consumes nearly nothing when idling. Firmware is 10f.
PS I am not trying to hijack the OP's thread. I just noticed the same behavior and I'd like some help on the same matter, as well as to contribute in whatever way I can. If the OP is offended somehow, I will gladly start a new thread.

@psolord No, not offended at all. I'm glad you posted actually.
My phone has encountered 20 more Alarms, wake ups since I left it standing:
com.google.android.apps.maps Wakeups: 50
com.google.android.gsf Wakeups: 45
You can see pictures below, the drop on the second picture happened when I was writing me previous post from P880.
- I am also rooted again (after factory restore)
- I have reenabled 3G networks but the signal is only at about 50%.
Any additional info please ?

Ok buddy, so we can keep discussing it here together.
For the matter at hand, I see the same behavior, when I unlock the screen, it's like I have opened a whole in the battery.
It dropped from 85% to 65% just from downloading a new map (500MB, 20min download on a slow wifi) from Sygic downloader. I mean this can't be right, right?
I also checked cpu spy and it reports the system 75% at deep idle, 15% at 51Mhz and the rest are 0% to 1% up to 1500Mhz. So if the cpu has so little operation, what on earth is draining the battery?
I wonder if we could be looking at a bad battery batch.
Is there an app that reports exactly what activity consumes power and how much?

Indeed, the hole in the battery.
I even restored to factory from recovery mode since I screwed up the root, so it was just stock, but guess what, nothing has changed :crying:
I really hope this can get fixed, else I'll get a replacement.
I hope someone from this forum with more experience can help :/

I think I am onto something.
Can you please check how is the phone doing if you disable everything under location and services?

I am going to try this, I am also talking to LG Support right now. WIll let you know when I get more information.

I disabled everything, and I didn't see pretty much any improvement. LG Support suggested me to return the phone.
Pretty much draining the battery atm so I can charge it back to 100% and use something like Battery Calibration. Maybe it can change something.

Yeah indeed I was onto nothing. Nothing changed for me either.
Playing 30mins of a 720P resulted my battery dropping from 62% to 50%. I also used the gps for the first time with Sygic (Jesus even the GPS is lightning fast) and the battery went from 50% to 30% for a 20 minute ride. It seems that my phone cannot give me more than 2 hours of use. That's just silly.
BTW do you or anybody, know of an app that can show battery usage per app?

Stock application ?
Also you can use Better Battery Stats to see if there are any wakelocks or anything is waking up the phone etc.

What is happening right now is rather strange, I disabled screen turning off (trying to drain battery to 1%/2%) looking at stock battery app, it seems to be stuck at 21% and it's not changing.

The stock application does not do so much analysis, but the batterystats you used above seems more like it.
I am getting panicked and I miss some stuff haha. Ok lets cool.
It makes me sad that we don't get any input from the community. Something like "yeah this is normal, live with it" or "your phone is faulty, take it back to the shop for a replacement" or something.

Agreed, ANY, ANY kind of input would be appreciated, but I guess we are getting none.
I am going to fully charge it today, do some stuff and report back tommorow. Also anyone, please do post any suggestion you may have.

Maybe this has to do something with the built in power saver. Maybe it kicks in when the battery drops to the 20s and stops whatever is draining it.
I am thinking trying some battery saver to see if it does the same thing but from the beginning of the full charge.

Actually I have disabled it when it asked me if it should turn on. So I guess nothing to do with that.

I am going to backup now, fully unroot and somehow get it to pure stock. Than I'm probably going to exchange the phone in case battery life doesn't change.

[Guide] Calibrating your battery

Ok so I'm going to tell you how to calibrate your battery, this is advised every time you flash a new ROM, you're probably asking why yourself why you would do this...
Advantages: every time you flash a new ROM your system gets confused and can result in your battery stats being incorrect meaning your phone might believe it has 0% battery and shut down despite having power left, this will fix this and so will actually give you a longer battery life
What you need:
The ability to read, and either
Cwm or the app "Battery calibrator" from Google play (I recommend the app)
OK.. so first charge your phone to 100% battery then go to either cwm recovery mode or the app, on cwm go to advanced settings and delete battery stats, on "battery calibrator" simply click the calibrate button and this will reset your battery data...
After doing either of these methods you're done, its recommended to let your battery drain completely before charging again but not needed...
I have included a screenshot of the very easy to use battery callibrator app... (having a problem with upload ill try in next post)
---I've definitely noticed that my battery lasts longer especially at staying over 80% before it would drain from 100 to 80 in literally half an hour now each percentage is equal and drains alot slower---
IF THIS GUIDE HAS HELPED YOU DONT FORGET TO SAY THANKS

There's no way to specifically see if your device needs calibrating which is why it's recommended after each flash, however if you believe your battery is draining quickly even while doing nothing on your device it's probably because you need to calibrate
Just uploaded the screenshot of "Battery calibrator app"

Clearing battery life wont give you a longer battery life. It just corrects the battery reading. Thats about it.

And other simpler way to calibrate is to reboot recovery - Go to advanced - Wipe battery stats.

When I clicked on the calibration button once it said calibrated....when I again clicked it prompted your phone is not rooted...I am running jellyblast rom....so device is definatly rooted....after some time it prompted this....moreover the app is not showing in superuser list....

The recovery method is in the guide, also this does extend your battery if your phone is switching off early because it believes you have no battery left when you do
Also to the guy who's having problems: that's normal after you click calibrate once you're done if you click it again you get that message

Yes, once you clicked it it's done, and if you click it again that happens... It's all normal, the battery stats will be recreated when you run out of Battery which is why it's recommended to let it all run out

Used my ACE without calibration (on Simplicity v3.5 Rom) - Phone was fully loaded, after around 10 min it was from 100% to ~90-85%.
This morning i calibrated and after ~10 min it was from 100% to 93% ... guess it helps?!

Yes it means it has calibrated your battery,
its giving a more accurate reading now,
P.S The only way this can help "Extend" your battery is if your phone was reading 0% and shutting down despite still having power left,
alot of people pming me asking how it extends your battery... So yes it can extend your battery.... sort of

Yeah, but i have to add:
I'm using "One power guard" atm - this app is really awesome and helps alot against battery draining - i like this, plus Supercharge, DOMscript and battery calibration - its really nice

Yeah I've recently tested this, it even has an official review by XDA, but tbh it basically just changes your CPU parameters quickly (Several other apps can do this such as frills CPU meter app) and when certain conditions are met such as low battery, this app is by far the best of its kind (Fully customisable and autimated) but ... I don't really need it my phone lasts all day even when I'm gaming... I only lose 5-10% battery ovetnight
It does have a nice layout and good features graphs etc but... meh, my phones working good already

[Q] Is it normal for my battery to be so bad?

Hey all!
I've bought my Optimus 4X HD recently. I'm loving everything! Except the battery...
Today, I've tested it again and here's what the battery is able to do!
- 6 hours of standby, 3G and Sync enabled
- 4 times checked mail for like 4 minutes total
6 Hours later: 30% remaining.
Is it normal for this battery to be so weak? I've "calibrated" (drained to 0% and charged to 100% - left it for a long charge the first time too)
If it's abnormal I'll contact the helpdesk and see if they can replace my battery, just want to be sure if it's normal or not.
Software is latest available, non-root, very few apps -- verified with taskkiller of AVG: nothing is running in background or anything.
Thanks!

I think there are some wake locks denying the system to go into deep sleep.
Search the forum for solutions, it's a well discussed topic on here

I usually get at least fourteen / sixteen hours on a single charge when I unplug it in the morning before work, varies with how long the Wi-Fi turned on, and I get at least three hours of screen time, one or two of voice calls. I also have mobile 3g data always on with alerts for email, Facebook and Google+. Usually I listen to music for about an hour and half too. I'm running the 20a euro rom official, rooted. Try factory resetting and rooting to remove bloatware and LG logging software.
Hope this helps!

Very few apps installed by you... there is a lot of stuff running in background that you don't even imagine.
Search for the threads about "battery drain" and you'll get some more info.

Do you run the new 4.1 Jelly Bean? There is some huge debate going on, how the update affects battery life. Personally, I ran into huge battery problems after updating to 4.1. The drain was especially heavy during the night, when I usually active airplane mode. With ICS I lost about 1% during an 8 hour night, under JB it was 20-30%. I read up on the threads in this forum and followed many suggestions. I started to monitor battery drain with different apps running/frozen, wifi, 3G, airplane mode enabled/disabled and so on. To analyse the battery I found the apps "CPU Spy", "Wakelock Detector", "GSam Battery Monitor", and "Battery Log" helpful.
But to be honest, I am no "android pro". I monitored my battery drain for over a week and did not find a satisfying solution for the problem. Thanks to this forum and many excellent posts I managed to roll back my phone to 4.0.3 ICS. Now my battery drain is the way I remember it and I am happy again
For me, this solved the problem. Although I do not run JB, and some of the enjoyable improvements it had, anymore. I know that for some people rolling back is no option. If you cannot locate the battery killer easily and you are willing to play around with your device (rooting, freezing apps...), you might as well roll back and give that a try.

You should explore your device and your stock apps...
My battery last in JB for so long as in ICS.
If there are differences they're small.

Yes!
Thanks all, very useful replies!
I've tried simply factory resetting it and, for about 3 hours it stayed on 100%, 2 hours on 99% and etc, very awesome!
I then set up my mail and other things and it went bad again. I had this sync symbol in my notification bar -- no clue why it was there all the time.
I googled why it was there and it's because the sync fails so it keeps trying. I removed the picasa for the email account (because uni mail doesn't support picasa and other google services) and my battery is top notch again! For now at least .

Looks like you're on WiFi which has good standby time. 3G standby is not good at all. That's when baseband_xmm_power starts acting up for me.

Following is my Battery usage still left some 17% with normal usage.

I've had terrible battery life... But when I went to cyanogen mod... It's been great for me ever since... Well two days actually. Lol
Sent from my Koala via the XDA App.

For me the same result with HSDPA. From 8:00 to about 15:00 oclock 15-20% of battery Just IM+ on, sync, some web browse + maybe one hour some games like beach buggy blitz or subway runner.

mine is bad because of the baseband_xmm_power wakelock, had this on stock 20A but didn´t had on 10h... as far as i can search, there is no solution other than revert to old 10h....
I bought a spare battery so i never run out of juice! Reverting firmware is not an option for me.

baseband_xmm_power wakelock, same problem here, battery drain cause this at v20A Jelly bean.

i believe this wakelock is affecting every phone since 20A, just install betterbatterystats and see it plague and suck our battery juice
