Hello, I have new LG P760. First thing, what I've done was update to Jelly Bean. But I experiences battery drain. Everytime, when I look at battery stats, there is Cell Standby on a first place and second or third is System Iddle. I've done hard reset and phone recovery in LG support tool. The problem is still here. Can it be hardware problem? Is there someone with experience like that? Sorry for my english
Exactly same for me. It happened after JB update. I found that device stays active even screen is locked when mobile data are on (battery stats app).
Conditions: factory reset after update, no additional apps installed
I hope just a bug and will be fixed soon.
Hello guys,
According to my experience, I think this is happening with you coz both of you flashed JB rom which is not for your country, there is no any solution to this problem until you got jb update for your own country.
I also faced same problem and got solved after update for my country (india).

ok guys
Now that may be a bug in update.
So I suggest you to take your phone to customer care or you can call someone at LG Care.

I think Mine condition is worse... I am on indian version of jelly bean. Battery stats shows 45 % cell standby and 45% phone idle....only 8%screen
Should i go to lg care

it seems like it is happening on all jellybean roms on all countries..
i also use official jb rom for my country (indonesia) and yes the cell standby and system idle totally drain my battery
well if this bothers you that much then maybe revert back to ICS is the best solution
Its exactly the same problem for me too!
I'm using official JB update (austria) and for me its the same too!
This isn't a nice experience!

Yeah I've noticed a increase in battery drain on my P769 running V20D.
On ICS my battery would last 2 to 4 days on average, but on JB I can barely get 2 days
Same here
I updated my phone via wi-fi with the official rom. And had the same problem. Battery drain. So i downgraded back to ics. I prefer battery life instead of project butter and google now.:good:
Now I'm just guessing, but it could be the google now app. Try shutting it off or don't allow the google location stuff.
Many were talking about the Google Now service which was a battery drainer. You should try and see the results. I also tried it,and the top 2 consumers were still Cell Standby and Phone Idle.
This thread might help with the battery drain. I think csrow found the problem

This is the same experience I'm having after the recent JB update on my P769. Battery life is now about half of what it was on ICS. Cell Standby at 35%, Phone idle 22%, Screen 20%, Wifi 11%..
Used to have plenty of juice mod/heavy use, was quite impressive. Now I have to carry a charger.
I too experienced crazy battery drains after upgrading to JellyBean (OTA update, P769 T-Mobile prepaid, pure stock, not rooted). I tried turning off Google Now after reading this thread, but it didn't seem like it helped much.
Last night we decided that my wife is going to use the phone instead, so I factory reset the phone before I gave it to her so she can start over fresh with her google accounts, etc. She left home this morning with the phone fully charged, and when I came home from work in the evening I checked and she had more than 85% left! Granted she didn't use it much throughout the day as she still carries her old phone, but she did use the phone to make some phone calls/chat and take some pictures. Just as a comparison, the last time I had the phone with me before the factory reset, the phone was draining battery maybe about 15%/hour just sitting on my desk.
So, for those of you experiencing battery drains, maybe you can try doing a factory reset if you haven't. I realize this is not something most people want to do unless it's guaranteed it will fix the problem, but if it's as annoying as my experience, maybe it's worth to try.

From what I've heard, it's usually improved - BUT some power management bugs that affected stock Gingerbread kernels but were fixed in all custom kernels are still present in ICS, such as the good old fuel_alerted wakelock - so while it's better when working well, it's more prone to breaking.
I'm happy if my battery lasts for a day as i'm always messing with it(one of these days I might use it to make a phone call)! Have you tried putting it on charge at bedtime? I find that helps a lot.

I would try to avoid over-charging it, it's not good for any battery. Once it hits 100% (so long as it's correctly calibrated) unplug and use as normal.

Upgrading to custom ICS roms is usually a great way to enhance your battery life, because they're always containing tweaks and optimizations!
This worked for me
Device: GT-I9100 (Samsung Galaxy S2 international)
Carrier: Smartone
Country / Language: Hong Kong
OS / Browser / build number (if applicable): ICS 4.0.3/IML74K.ZSLPE
I can confirm that I have resolved the battery drain issue after upgrading to ICS on my device. The problem was partial wake locks caused by the exchange service.
One of these measures fixed the problem for me (it might have been any of these, although I have a strong suspicion that the factory reset is the only relevant one):
- factory reset of phone; didn't restore the settings and accounts, but set them up manually
- wiped cache
- did not reinstall ADW launcher
Hope that helps.
The good news is that now the battery life is definitely better than it was on Gingerbread.

This isn't really true. Once it hits 100% it pretty much runs off the charger.
By depleting it all the time you are ruining the battery that way

Leaving your phone on charge longer than is absolutely necessary ie taking it off charge as soon as it gets to 100% will not affect your battery life and there is also no need to manually calibrate the battery. I installed DXLP7 and was getting poor battery life due to a wakelock, I found and dealt with the cause and immediately battery life improved. In my experience battery life on ICS is as good as it was in gingerbread. Better battery stats is your friend.

I had upgraded my sgs2 to ics yesterday. The new version is draining the battery very seriously. In the previous version, my sgs2 could last for about 12 hours from a fully charged state. But now the version can only last for 6 hours, which is really unacceptable.
Is deep sleep? You can check with CPU-Spy. If not, remove the battery a few minutes and then returned.

I had huge battery drain issues from exchange and email waking the device and constantly doing something. Removed the accounts and then set them up again. Like night and day now, better than gb. On LP7 and never wiped.
Cheers

Keep a look with BetterBatteryStats, and see if there are any apps messing up.
I have better batterylife with ICS by a margin.
And about leaving the charger on during night, these are kind of myths really, you can keep it on without any worries, and also charge it without being totally drained.
Most of these thoughts come from the old Ni-Cd times with memory effect.
I had removed the Exchange Account yesterday and the battery drain problem disappeared. The account was added back after about 10 hours. The battery usage is now back to normal (a little bit better than the situation before the ics upgarde). Thanks for your hint.
Cheers.
SG S2 ICS Battery drain issue
Had upgraded to ICS when it launched in India and literally went berserk due to the battery drain issue. Googled and googled, found a lot of things, tried most of them (except for changing ROMs).
Then, Voila, last 4 days - a complete twist to my sorry tale. I first disabled the phone backup option (to Google), did a factory reset, said No to most of the options that are asked on restart, and didnt install the earlier applications from the Play store en masse (earlier, had a number of games and other 'what I thought was useful' apps). Now, only have the basic apps plus Poweramp, Shazam and NQ Mobile added. And the result - the battery is back to normal. Phew....big relief as I use the phone pretty much for mails, music, phone.
I want yo add some thing very annoying, I discovered today after upgrading to Resurrection ROM.
In fact, even with the device connected to my car power supply and using Copilot for about 1 hour, the battery continued it's discharge instead of charging.
So what to say and what to do?
Cheers
Hi,
I have recently (half a week ago) updated my SII to Jelly Bean from ICS. It's fully stock without root. However, I noticed right away that the battery started draining very quickly and the phone sometimes gets hot. Did a factory reset. Factory reset the phone and format the internal SD and remove the external SD. Didn't help in the slightest. Phone starts draining after resetting. I have tried to flash another stock JB ROM (XEU) and afterwards factory reset the phone again. No dice. I installed CPU Spy to see CPU consumption and it says the phone didn't go into deep sleep at all and 95% of the time it was at 200 Mhz over an 8 hour period or so. So there's a wakelock that's keeping the phone continuously on.
At first, "Media" in battery settings in Settings was the culprit, it drained about 50% of the battery. I have searched the web and it's a pretty common battery drain on JB. I did try to disable the service and its battery consumption went down dramatically. But for some reason it turned on again. But right now Android OS and Android System are both draining most of the battery. I have also installed BetterBatteryStats and according to that app there is a partial wakelock called "NlpWakeLock" by Google Services that's draining most of the battery. Last night, around 60% of the battery got drained overnight (80% > 23% to be precise). Which, clearly, is unacceptable.
I'm at my wits end. I have no idea how to solve this and because I really like the new JB features I don't want to go back to ICS (I did a fresh ICS install and the battery drained 2% overnight which is how it's supposed to be).
If there's any information you need to know let me know. Any help is appreciated!
Go back to GB with speedmod kernel is an option.

Do you mean going back to Gingerbread? I haven't figured out what the speedmod kernel is yet but if I were to switch back I would rather switch back to ICS. But preferably I'd stick to JB since I do love all the new features and options. I'm willing to flash another JB ROM without the battery drain issue. However, all stock ROMs that I have tried had the issue.
Do you know of any good JB ROM? I prefer to keep it as stock as possible. I did root when I had ICS installed though.
Battery Drainage is very common in JB Stock

Well repeating other peoples posts isnt helping anybody.
An update. I've installed the XEF update initially it had the same draining issue. However, I've also cleared cache and data in recovery mode and it seems to have solved most of the issue. I've got pretty good battery life now (about 1%/h idle).
But I did find another culprit draining the battery which is Dropbox. According to BBS the processes "wlan_rx_wake" and "h2_hsic" were draining the battery but I've uninstalled Dropbox now and it seems to have solved the issue. I really use Dropbox regularly though. Anyone got any idea what could be causing that?

I have always had that feature disabled since I don't want to use it anyway. I have no clue what could be causing it. I want to use a packet sniffer to see what is sending and receiving data but the phone isn't rooted so I can't really do that unfortunately.
Hold on, I'ma freeze it with TiBu.
Test time.
PS: You really need to root that phone.

I just greenify Dropbox (actually, all apps which rely on an internet connection). Unfortunately for you, it requires root. IMHO, almost worth rooting for, although there's many better reasons than that.
Greenify is almost like a temporary freezing of the app, by stopping all background processes for the app. They automatically restart when you launch the app, and automatically turn off when the phone goes to deep sleep.

Well Dropbox always keeps on syncing stuff from the cloud and that might the real cause You should disable all the automatic syncing and keep it to manual sync as it syncs only on your commands and saves your battery!!

Check how much data is being downloaded. If a lot is being downloaded off WiFi, switch it off and see if that stops your drain. Then switch off Data on your cellular. Just to check which one's causing the drain. Believe it or not, I just rebooted my home wifi router and battery drain issue was over on my Galaxy S2.

I had previously rooted my phone when I was on ICS. I never used it too often though. I wanted to use Nandroid. I have no clue how to root JB though, without flashing a modded kernel (which I did with ICS).

That's very interesting. This might just be a good reason to root the phone. So I can use network log or shark to see which apps are sending and/or receiving data. I have this feeling Dropbox is going to be one of them..

Hmm, but I guess that you can't really freeze apps like Whatsapp, since you wouldn't be able to receive any messages then until you turn on your phone. But I'm getting convinced to root the phone again so I'm definitely going to give it a try.
I bought an LG Optimus L9 P768 from a friend (my 1st smart phone ever), who has updated it to JB. I noticed that the battery behavior is not usual; I charge the phone about 3 times daily with only minimal 3G internet browsing and few calls. After some googling, found that some people reported the same battery drainage directly after the JB update.
My questions:
01- Has there been any update or patch to solve that battery problem?
- checking from the phone returns "You are using the latest software version for current OS."
- using LG Mobile Support Tool yields " Your device has the latest software available from the LG Mobile Support Tool"
"Software version V20A" (SCREEN ATTACHED)
02- As an Android primitive caveman, the 1st thing that came to my mind to revert the phone to ICS. Using "Update Recovery" in LG Mobile Support Tool.
- After asking me for my IMEI, it downloaded a 500+ file, then failed TWICE at 5%. (SCREEN ATTACHED)
03- I stumbled on [GUIDE] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX METHOD [UNBRICK], but I cannot figure out how to get the official stock roms.

NOTE:
- I'm not in love with ICS or even the official roms in general, I just want my battery to last as it should be without any weird application behavior.
- Any suggestion with any trusted custom roms are much appreciated as long as the battery will work properly.

- Any suggestion with any trusted custom roms are much appreciated as long as the battery will work properly.

Charge phone to 100 but leave it charging then factory reset and remove cable. Tell me if you see any difference in drainage after a few hours.

Despite of the fact that I did a factory reset before starting this thread, I did it again as you described with the cable on and then removed it. Unfortunately, the problem still persists. Using Opera mini on a 3G connection with 50% brightness drains the battery on the rate of 1% every 3-4 mins.
not sure about the battery problem only being with jb. but i could surely help you with rolling back to ics
and the website you found for lg firmwares is perfect. i guess everybody on the forum uses this website.

I succeeded in reverting back to ICS stock rom (downloaded a random 10A one from that page), followed cmahendra's guide and the unusual Cell Standby percentage is gone. But my impression is that the battery usage is still relatively high; why don't we, L9 users, make a standardized battery benchmark? using Antutu Tester for example, so that we don't rely merely on impressions.
I'll start by sharing mine. (See the attachments)
I know it cannot be that accurate due to different ram and cpu usage, which Antutu cannot control, but at least gives an approximate picture.

Hi, I'm havin the same battery drains after JB update, specially from cell and phone idle (ridiculous). I did the Antutu test: full charge, begin test and I lefted it with no use overnight; and I scored 463 (aprox in the middle of the chart).
How old is ur phone?

Original date of purchase is in last April, then I bought it in August from a friend. I don't think it's old enough to cause this unusual battery drain. Don't you think so?

I tested with Antutu again and the score decreased; 1st time (on ICS) was 399, 2nd (on ICS) 370, 3rd (on JB) 326. I think we need more users to share their test results.

Yeah, more results would be useful. I asked the LG support for help with this problem, they haven't answered me yet... I'll tell you if they do.
Solution?
Hi, I tried something that worked for me. I did this 2 days ago and yesterday I went from 100% battery at 9 am to aroud 40% at midnight. Apparently the battery needs to get calibrated after the update. Anyways, what I did:
Use your phone normally until battery gets depleted and the phone turns off by itself.
Then plug in the charger and turn it on again (you have to wait until the yellow icon dissapears)
After I turned on I saw that the battery was around 25%, wich was ridiculous considering it was depleted and it was charging only for 5 minutes, so I plugged off the charger and let it reach 1%
When almost depleted and before it turns off again plug it in and let it charge for a while (I left it overnight)
After that the battery estarted to work like before the update to JB. Phone and cell idle are still the most consming apps though, but well...
It's 2 days after that and battery is working fine, I'll update you if anithing changes.
PD: no word from the LG support... -.-

my first and last LG purchase
Hello guys. I bought a Galaxy Note i717 from ebay a few weeks ago. I planned to use it as a spare phone, so I normally kept it at home for my nephew to play videogames or used it for work, always on airplane mode connected to wifi. Two week ago I started using it with a sim card and I noticed the battery drains really fast. I purchased two OEM batteries thinking it might be a problem with the battery, but it wasn´t. Battery holds for approximately 4 hours with normal use. I tried a factory reset but it didn´t worked at all.
Phone is running stock 4.1.2 since I got it. I was thinking on rooting and installing a custom rom and kernel, but I am wondering if it is some hardware issue because in come cases I´ve noticed the phone is a little bit overheated even without using it to much.
Any advices? Should I try the custom rom or did I lost my money?
When the Note was updated to 4.1.2 Jellybean alot of users complained of rapid battery drain. There are some great roms out there..Bigfu or Ptrm3..just search development. I have tried them all and they all have something to offer. The developers here are great for us average users who sit back and wait for a new rom. The At&t update was horrible for me used it one day then switched to custom rom.

You mentioned that the problem started since you put a sim in it. Could the problem be that you are in a weak service area and the phone is constantly searching for a better connection? That can kill a battery quickly without using the phone.

That´s the moment I started noticing the battery drain because that´s when I was using the phone regularly. Before that, I just left it at home for my nephew to play some games or just used it for sending some work emails at home, so I never noticed if the battery was running out fast or not.

I didn´t knew anything about the users complaining after 4.1.2 update. I will take a try with a custom rom, I hope that is the real problem and not a hardware problem.

I see we have the same problem. I upgraded to 4.1.2 just when I got it, so I can´t tell if the upgrade was the cause of the battery drain. I will try flashing a custom rom.

Hello to everyone
I have some issue with battery, camera, ram memory after update to android 5.0.2.
First the battery, my screen light is 40% all the time, i use viber, whatsapp, messenger and chrome about 2h a day. Before the update, my battery life could stand approximately 2 days without charging now is about 4-6 hours a day, Does any of you have the same problem?
Secondly camera, when i shoot a picture from a distance of two meters I realized that the image is blurry in low light, but when i take a picture with flash, phone can't focus the object, in daylight the picture is pretty ok.
And third RAM, after closing down an app, and again open that app i realize that phone force stop that app, but after closing a chrome browser my screen freeze for two seconds..
I lost some Features, smart pause, widget on lock screen, plug and pop, LG Software when plug usb to pc, lost two or three options in connecting method?
I apologise for my bad english.
Thank you in advance

It's official version for east europe.
OTA.
I used 5.0.2 from first release and I can tell you the truth. It just sucks. LG probably released this update without fixing bugs to make people angry... They did it intentionally to tell us "Sorry, but your phones are aging. They can't handle it better" and forcing us to buy new smartphone. Sad, but It's true. On Lollipop I saw they fixed some things that was broken in Kitkat like GPS, blinking screen on low brightness (in my opinion they just increased minimal screen light equivalent to 10% on kitkat but I can be wrong) and some others. Battery life is worse and RAM management is terrible. I tried to make swap partition or test some settings on Low Memory Killer but without success. Phone started lagging and freezing from sometimes to often. 2 days ago I returned to kitkat and I am on ART. It's faster and more stable. I recommend you to flash good old 4.4.2 too
Some people will probably tell, that fresh rom is always faster. It's truth, but my uncle have D620R too. He's using stock and updated Kitkat on dalvik without root. When I get his g2m in my hand I just noticed that Kitkat is much better compared to my slow Lollipop

Would like to ask which software version you guys have? I have the V20b-esa-xx
Update
I have been testing out 5.0.2 on my D618
Here's what I have noticed:
The image quality from camera is the same, gps is still bad (still tells location inaccurately), speed is the same as it was in kitkat, and I believe battery is almost the same as it was in Kitkat. There are also some added and removed features and added lollipop animations

After checking out for a few more days, I can definitely confirm that the battery is a bit worse that it was in Kitkat. A few days ago, after I woke up in the morning the battery went from 24% to 14% (It went down by 10% just being on standby). Plus, I tried charging the phone overnight but to my surprise the phone is not event fully charged yet? I slept at 10:30pm and I woke at 4am, I checked the phone it's still charging at 98%...
Anyone know's how to fix this? I'm getting terrible battery life and one reason I bought the G2 mini over others is it's battery life...
