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.

3A- Will any rom with the same model, i.e. p768, work regardless to the country?
3B- I also found THIS but the website looks suspicious, doesn't it? tried downloading that one from United Arab Emirates section, as it's the closest to Egypt where I bought the phone with it's working warranty in country, but I always get "Size mismatch after 23%".
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.

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 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... -.-

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.

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
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).

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.

update: the wifi radio is always on change the setting as of csrows thread it is always on even if you dont have it clicked it has improved my battery some but much more is needed on alot of things im working on things ill update you all when i figure some things out
Just for those who don't know where this setting is:
System Settings >> Wi-Fi >> Click Menu button >> Choose Advanced
Change "Keep Wi-Fi on during sleep" option to "only when plugged in" (or "never" if you want).
4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

Hi OP,
I haven't been on the i9100 for that long, but have also been annoyed with short battery life. As have many others from what I read. A 12% drop over about 8 hours of sleep, I'm sorry to say, doesn't seem that bad actually for an SGS2 with stock jb 4.1.2 and stock battery.
Personally, I tried different lightweight ROMs that are known to spare your battery. The advice to turn off 3g and other core functions never made sense to me, as I want an operable phone, not some sort of deflated piece of junk.
After reading on xda I went through Slimbean , Liquidsmooth, and other ROMs to see if they would increase battery life.
My current ROM is NeatROM 4.8, which actually seemed to give better results. Please note that this is purely subjective, though, I have no fancy battery analyses to back up my statement.
What REALLY helped was getting a replacement battery.
I tried Qcell 1950 mAh batteries. Stay away from those. They are clearly not 1950 mAh. Now running with a genuine Samsung 2000 mAh which is worth every dime.
Now I imagine you would be frustrated having to buy a new battery just because you updated your firmware and I do understand. I never owned the SGS2 before jb, so my choice was simple I guess. That having been said, though, the 2000 mAh battery really turned the phone into a whole new sort of usable. It easily lasts through the day even with regular use.
Just my 2 cents.

yea.. u said it...even i have tried several custom roms ( NeatRom, WanamLite,RR etc) all give 15-19 Hrs max.. and this also by tweaking all the settings..
S2 is a undoubted beast, but the cost in terms of battery is very hight..my previous Android Motorola Defy was a Mammoth in itself..huge custom fanbase and loads of ROMS + Awsome battery.
Any ways i got no regretts for having a S2..but battery s a lil concern..
Currently am on Asnet MIUI V5 and its going good..fast, responsive, smooth and decent battery of 18 hours avg..
@jsiv - i wanted to ask u a question.. which country u hail from ?? because the stock 2000 mah battery is not available in India, my region.

What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?
I live in Denmark. I ordered it off Ebay, but I see now that the UK shop I got it from doesn't ship to India.

Can you please point me in the "settings" direction? I think I'm doing all things right, going real low on app usage, sync-ing of apps, screen settings, etc.
What exactly is battery calibration here? Please pardon my ignorance. I did a full charge when my phone hit got switched off the day after upgrading the OS. Is there something else I must be doing here?
I've had this problem right after the upgrade. So, I don't think it's an issue with my battery per se. It could just be JB.
How good is the Cynaogen Mod ROM in terms of battery life?
Or would it be wiser to switch to Android 4.0/ ICS?

This has to be done every time you do a ROM upgrade or change ROMs.
CM has excellent battery life when compared to other ROMs.
If you are switching over to ICS stay away from version 4.0.4 as it has EMMC brick bug.Any other version would be fine.

4) and it's very very annoying... so much so that I sometimes (multiple times in a day, actually) wish to get back to Android 2.3.3, which I had before updating to Samsung's (India) version of Android 4.1.2 for my GS2.
What could be the problem? I rarely ever connect to WiFi (am always connected to GPRS/EDGE, but that has never been a problem in the last 2 years... the phone still used to get nearly a day of battery life) and the brightness is almost always at the lowest. I rarely use Bluetooth, GPS, etc. I don't even use Facebook and WhatsApp anymore, so the screen isn't used to the max. I've turned off all the Location Sharing settings for Google Maps and/or other apps (I use very few apps anyway, but have a bunch of them installed on the phone... none that execute in the background though | also not more than a couple new apps after my OS upgrade).
It's been nearly a week since upgrading the OS on my phone. Last night when I hit the bed at 1.15AM my time, the battery was at 100% (after charging). With no activity whatsoever in the night, the charge had dropped to 88% by 9.35AM. That's less than 8.5 hours of no use and 12% charge gone. That never was the case earlier.
Also, for each minute of using the phone with the screen on, I notice 1-1.5% drop in the battery. That is, to put it very very mildly, PATHETIC!!!
I don't know what to do. Would a "clean rom" install help? If so, what exactly is a "clean rom" install?
Or should I be doing something else?
Any help would be greatly appreciated.
P.S.: Please let me know if any other info is needed too. BIG BIG Thanks in advance to anyone reading this

As reported before, it seems that many official JB ROMS are not as optimized as other national versions and are battery hungry. It was suggested to upgrade to the French release (XEF).

I did this... and unfortunately, it did nothing in my case.
I went to the CM site, but I didn't find any stable build for SGS2. Is there a thread on this site I can refer to for the same?
Also, what's the best way to go about installing a different ROM? I have so many apps, sms messages, pics, mp3 files, 3gp files, etc. Sure I can take a back-up onto my SD card. But won't I lose all the apps once I flash the current Android installation and install a new ROM? Any article or video on YouTube that addresses these points? Please point me in the right direction. I practically don't use my phone even half as much as before and I'm having to charge it twice a day, as against once a day earlier.
Also, the rapid battery loss seems to be causing the phone to heat up a lot if I'm on a call longer than 15 minutes or having the screen on for 2-3 minutes straight.

There is no stable version of CM 10 on I9100 because of the some issues. You can flash one of the nightly builds.They might not be necessarily unstable.
No you wont be losing everything when you install a new ROM.You lose once you do a data wipe.It is suggested you wipe everything before you install a new ROM.
With a data wipe you'll lose the following - SMS,contacts,call logs,apps installed and respective data.
What you wont lose - Anything stored in the sdcard partition - Pictures, Videos, Music, Apk files and Anything stored on the Ext SD card.(unless you format them specifically)
Best solution is to use titanium backup app(You need root). This way you can backup your apps and resp. data,wipe data-install ROM,and restore the previous backup on the new ROM.

As far as the battery issue is concerned,do a clean ROM install through Odin.

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

On my d620r with v20c vodafone and v20c poland gps works better. On KK I must wait longer to get fix and it drops connection often. You can try fastergps from google play if you have root

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...
Hello everybody, here I am for some informations about the battery life of galaxy alpha. I am using an official stock rom 5.0.2 of Samsung. I charge my phone 2 or 3 times per day, but recently I check the battery usage in the setting and I see the wifi seems to be actived all the time even I set it off. Please check the attachment file for screenshot. I just wonder if the problem comes from firmware or I just have to change my battery?
Best regards

I don't know which firmware I have to use, I'm afraid I will lose all the functions of Samsung. I had flashed the cyanogenmod on my old galaxy note, it's not stable at all. I just hope the Alpha will receive any update (marshmallow) even this may not be happend.

Yes, I am using this battery and it is perfect (2500 mAh instead of 1860), but it hasn't NFC (I don't care... never used it)
Does it last longer than the 1860 battery? There are cheap ones on eBay that claim to be 2500, but I doubt they last longer than the 1860.

I am on official firmware update from OTA, if I flash the official firmware from sammobile, it's the same thing I doubt... I am in France, if I flash the firmware that come from other countries, I'm afraid it wouldn't run correctly and there's maybe some problems with the network.
Wi-fi location scanning
There are two possibilities for excessive battery consumption with wi-fi. If your phone is set to always scan, then this will still cause the battery to drain as the wi-fi is never really disabled.
Disable this function with 'Settings > Wi-fi > advanced > always keep wi-fi on > never' the advanced settings are under the little 3dot menu at the top right of the wi-fi settings screen.
The other option may be that Google's location services may be causing a drain by using wi-fi to geolocate you.
Try disabling location services for a day and see how it pans out for you.
If neither of these help then I'm all out.
Good luck

Is the battery thicker and do you need a different backcover to fit the battery?
