[Q] Battery drains over night on my LG p500 - Optimus One, P500, V General

I have a LG optimus One P500 with 2.3.3 stock OS and i have high battery consumption . i check the battery status in the morning and it shows that cell standby and phone idle takes 45 - 50% after 1d and 6h .
Is this normal ? It happens every one or two days. So when i go to bed the device is charged but in the morning i have 75% of battery left.
excuse my english !
P.S. with only 3 or 4 apps installed ! that does not cosume battery .
Please help or advice!

Hmmm doesnt seem normal.I get just 1-2% battery drain overnight,but i have rooted my phone and installed franko gb kernel.U can read the guides and try installing this kernel.
P.S:I also had somehow high battery drain with stock kernal,but not as much as yours.

I had a similar situation once. I fixed it by copying all the files off the SD card, format the card (using the menu on the phone settings-storage-format) then copy the data back.
It appears a something was going wrong with the card.

thanks i will try this at first and see if the problem is solved . If not i dont know...

It drains battery on GB !(Lg Optimus One P500)
So after 13 hours my battery was at 19% on my Lg P500
I checked in Settings/applications/Battery use and guess what :
Cell stanby 31%
Phone idle 30%
voice calls 39% , and when i tapped the meter on top of the display to see the graffic i found out that the line assigned to "awake" it is uninterrupted.
And now after 1 hour after charging the battery use section : cell standby 50%
phone idle48% and display 4% ! AND all the lines in graffic are also uninterrupted.
ADVICE NEEDED !

If the Awake bar is uninterrupted, then some background apps are running continuosly in the background, even when the phone's screen is off. This should not happen unless you have turned ON data-sync and if you've applications which try to connect to internet every 10 mins like facebook, twitter. Check these. You can see what are all the applications running in the background in Settings -> Applications -> Running Services

Yeah...such applications do sync often and you have to make sure that they dont sync every 30 mins for example.
Having root and installed setcpu could makes such differences, for instance, you could make a custom Sleep profile, which undervolt your cpu frequencies when the display is off. Having this and your phone could get enough sleep while you were

Did you transfer songs or any other media recently? My stock phone had a bug wherein a new media transfer would trigger an unending SD Card scan which would suck battery like Ms. Jameson.
I solved it by deleting those files.

How did you discover that this bug was active? Would it actually keep saying Scanning SD Card or something? Because I have had noticeably higher battery drain just yesterday after transferring all my old files back into a newly partitioned card + newly flashed ROM. Just using the ROM and card before moving the files gave me a maximum of 1 day and 5 hours... Today it went to 50% in 8 hours.

I did but by usb cable. After that i erased all data.
Today after 12 hours i have 76% left . It's very strange! Do you have an explanation? I wonder.
Thanks

Oh so that worked? Great.
I was testing a friends music player app when it happened to me. I told him that his album art rendering was very buggy, so we both ended up investigating and he found that the stock rom was performing continous scans. I didn't see icons or anything.

How can you tell if your phone is continuously scanning the sd card?

We at caynogen mod 7 enjoy the sleep button about zero percent change in sleep mode ...its great .. well I was no help to you but I hope you fix your problem

Indeed it's drained battery terribly after upgrade stock rom to official version 2.3.3 (V20D in my country). I have the same problem as well. I found it 25% battery life gone after 4 hours from fully charged status before upgrading to version V20D. I did try playing or testing the GPS & data network 2G (GSM) around after done upgrade. Previously in V20G Android version 2.2.2, 1 full day drained battery for about 30% only.
I have tried GO Launcher EX app before on v2.2.2. I wonder if I should install this launcher app again. Will Launcher app drain more battery life or save power battery? Seeking any recommendation from xda experts here. Please advise.
Thank you.

drains no more
Now that you have 2.3.3 you must kill some apps . try in settings/apps/running and see what apps are active ,then you go to all apps and close apps that are running.
In my case google maps , facebook , yahoo mail and another 2 apps drained my battery . So i closed them and it's ok ! Now every time i use them i stop them after.

if you Maps installed then Uninstall it.
it starts up any time it wants and takes a lot of battery.

Hello.
First I would like to thank istoner for the this great advice. I had the same problem with my optimus one and this helped me a lot.
I just bought the phone a week ago and about 3 days ago i installed winamp app and transfered a few mp3's on the sd card. Just last evening, when i stumbled into this topic, I realised that my high battery drain problem started just after i did the fore mentioned changes to my phone.
Yesterday(data from "Battery use" in Settings) with ~14h since full charge i had like 20% battery left with moderate use during day. So after that, I followed this advice and removed the whole folder from sdcard containing the mp3's and let the phone charging over night again. I used the phone with the same moderation as yesterday. As i'm writing this i'm reading from "Battery use" a 13h 52m uptime since last full charge and my batter is at 74% percent left.
I can't tell you how glad i am i stumbled into this topic. I was just ready to uninstall all my apps and possibly get the phone in service.
I find this a somewhat important problem of the cellphone and i think more users should be informed about this. Could be a nice addition to some faq/tips and tricks topics.
I still have a couple of questions though and i hope someone will be nice enough to answer them.
What could be the cause of this problem? The android os(upgraded official 2.3.3 from stock 2.2.*), the phone's hardware or the sdcard?
What is there to do if I, let's say, go on a trip and i need some music to listen to on my phone?
Thank you.

i highly recommend to FREEZE it using titanium backup pro..
den unfreeze it if your gonig to use it

Afaik Titanium Backup is for rooted phones. Mine is not, as i said i'm using official 2.3.3. I don't know if i'm gonna root it atm just for using titanium backup.
I still hope there is another workaround that doesn't involve rooting the phone.

I started having the same problem a couple of days ago too. I think it is one of the apps that I recently installed from the market (flight view). I did a hard reset (uninstalled the battery while phone is on) and everything was fine for a day or two. Then it started happening again, so I suspected it was that particular app since it was there in "Running Services" despite not starting it. So I just uninstalled it and will see how things go.

Go into settings and make sure all Auto-Sync options for updates and social web sites are not ticked, if they are ticked these run constantly to check status check them manually when you want to, also turn WiFi on and off manually don't leave it on all the time.
Had the same issure. Apparently the problem was 3G/EDGE data transfers. By disabling all data transfer battery life was improved a lot, but then i needed internet frequently so having to turn on and off data transfer wasn't the best idea. Flashed the phone with generic firmware, and so far battery life is decent.
i'm having crappy battery on the latest update 2.0.2.A.0.24
i'm using the rooted version and JIT v2 enabled.
lost 15% in 6 hours last night with the phone not being used at all.
cell standby is killing my battery (57%), but i have good signal strength.
phone idle is at 17%, display 15%, system 5% and acore 3%.
something is going on with the cell standby.
i can't figure out if it's because i'm using google voice or something else.
something else is that my phone is now listing it's model as x10i, when it's an x10a. i know this is because of the generic update firmware. but i wonder if that has something to do with the standby battery drain.

FYI - total battery use must always add up to be 100% - It may appear that the cell standby is using up the most resources.. that may not always be the case. Check your time without signal..
Hmm it seems happen to me too since I tried Jit v2. Will try to revert back to v1. Will report back when I tried it.

Alright, so to update you guys, it has been 2 days since I removed the "culprit" app called flight view and my battery life is back to normal. So, if you all of a sudden see that your battery life is reduced, then go back and check the latest apps you installed. It is probably one of them that is causing the problem. Hope this helps.
I agree with certain apps constantly running in the background draining the battery. One way I found to determine what's doing what, is by using Advanced Task Killer, and periodically checking to see what apps are running(without being opened by myself), then killing all apps, then check back in a minute for the culprits. If it started up again on it's own and uses a lot of resources but I don't use it every day, I disable or uninstall it. When I need it again, I enable or reinstall it.
Also, set advanced task killer to kill all apps on screen off. That will help your standby time. Set apps you need running in background, like messaging, to ignore.
Also, turn down the brightness of you screen, and shorten the screen timeout length. They all can add a few seconds and a few clicks to certain tasks, but I still have 30% battery the mornings after I forget to hook up my charger the night before.

The problem is I don't install new apps after applying Jit v2. And my battery works fine with Jit v1. Well today I tried to remark #dalvik.vm.execution-mode=int:jit. Let's see how the battery performance today. ^_^
Btw the linpack score is still the same around 32.

I've deleted some recent apps and my battery return to normal.
It might be because of apps running in the background. Things like moixer mail and track id is notorious for battery drain issues. Better get them removed via titanium backup

If you updated your X10a into X10i, and you are now experiencing battery or connection problems it could be due to the missing cell broadcast widget called Cell Information only found in the X10a firmware and possible other unknown differences.

[Q]*UPDATE 17.06.2011* Battery (Its not another complain thread)!

I know there are a lot of threads already but bare with me....
A lot of users have been having issues with battery (me inlcuded). These are the following things I have personally tried:
Screen Filter
Freezing Apps in Titanium
Green Power (though I had issues with it not enabling data when screen on)
I have tried VillianRom the CF-Kernel and currently I am on stock K7 and the stock Kernel (rooted using insecure kernel then flashed stock again)(figured that might help since Samsung wouldn't actually sell a phone without testing the battery).
I am not a gamer nor have I been abusing my phone. Today scenario:
(3G/HSPDA always switched on or wifi when available)
Removed phone from charge at 1400 Hours.
Wifi was on till I left home at around 1530 hours during the process I must have barely checked a few messages on Whatsapp and made one phone call. Since then I have been out met a few friends showed off the phone. When I say showed off the phone all I did was this:
Showed the S2 playing a video
Played a song from google music (streaming over 3G)
Used whatsapp for about 10 minutes
Spoke on the phone for a total of 30 minutes
Got back home around 2200 hours and the phone was screaming for attention which I believe on stock is around 15%.
As you can see from above I have hardly used the phone. Now my query is for those users who are not having battery issues. We have had a lot of threads complaining about issues can we just have a brief post from you guys who are having fantastic battery?
Something like:
Firmware
Rom
Kernel
Root Status
Applications Installed/Frozen
Other Steps?
How much juice have you gotten out of it
I think all of this would greatly help. Coz clearly some of us are having problems and some aren't so could we just share the knowledge?
Sorry for my rambling but I wanted to explain all of it as clearly as I could. Instead of starting another thread as to WHAT CAN I DO!?
Cheers.

[UPDATE]
I read this in one of the countless threads regarding battery life and android OS eating away battery. Still in the testing phase but it seems this might be a genuine solution as well :
Format your SDCARD. I know sounds stupid but like I mentioned earlier I am still testing this out. Most of us if not all have shifted from our old android to the Galaxy S II. The probability that this might have been without a format to save pictures or some sort of data is most likely. Once again this *might* help. The title hence states update and not *FIX*.

after all this mods and stuff i barely got 21h from it with a very very light usage .. now on standby my phone dropped from 100% to 90% in almost 4 hours of nothing
hope this problem get solved with 2.3.4 update

Other Steps? : Wifi on most of the day, 3G off unless necessary. GPS off Screen brightness: auto
How much juice have you gotten out of it: 4 hours of screen on time, or 24 hours of light use. Usually 16 hours of 3.5-4 hours of screen time.
I hope this helps. Ah not to mention, I have had this phone for 5 days now, and I haven't had ANY Samsung apps show up.
Here is an image of my list of services, but I must say, I unplugged it last night at 10 PM, and left it mostly alone until this morning. That's why my screen usage is so low. In other threads i've posted a lot higher screen on time . But it's just to show you that on KE1 there is no Samsung services going rogue.
One step forward two steps back while charging!
I had the bizarre issue last night where my S2 was losing power while it was charging. Only app running was Words with Friends (checked cpu usage and seemed ok) and I had Screen Filter running at 60%
Phone was near dead by 9pm even though I had topped it up during 2x 30min drives. Was playing Words against 4 family members (all on their iPhones) and I had to give up trying to play while huddled on the floor by the socket as it slowly dropped percent by percent lower.
Not Happy!
KE7 btw
I had a ****ty battery life too but then after reading some tips how to improve it, I froze wifi sharing in Titanium Backup and disabled Google Latitude (not sure which one did the trick but if I had to choose, I guess Latitude was the issue since Maps was always showing up in Battery usage) and now my battery life is perfect. Before my phone would die after like 8 hours and now 24 hours is no problem . I hope the new firmware will fix Latitude but until then, battery life > Latitude. I'm on VillainRom 1.1 and CF-Root 3.7 btw.
ActiveSync
I had an activesync account which really chewed on my battery, had only about 12 hours battery life. After removing the activesync account it lasts at least 40 hours!
i have mobile internet on 24/7, everything syncs every hour, if i dont touch my phone all day, it drops from 100% to 90% from 8am to 4pm....I use my phone for music most of the day for music, txting ect, easily has over 50% by end of the day...cant understand why so many people have problems!

Battery is always the problem and it will hinder the development of smartphone or other PDAs. Maybe we should get nuclear battery
Always turn 'mobile data' off when you are not using your phone. I travel a lot with work and can tell a huge difference in battery life depending on where I am. If you leave 'mobile data' on where 3G service is bad, your battery will drain fast.

Other - 3G connection, no 3G packet data, no WiFi, no GPS, looking at the time from time to time, screen brightness either small or auto
I have none of the problems mentioned by others (like display banding, tint, unstable WiFi, the pink camera spot is small), if this makes a difference.
(By the way, the number within the battery compartment says i9100H)
I get about 11% battery discharge per 24 hours

Whichever way you swing it, Android battery life ain't that great... i'm coming from a Nokia phone which had 7-10 days per charge.
S2 is my first Android phone it's stock unrooted, Optus Australia version. With 100% wifi on, I get 9 1/2hrs out of box, 19-20hrs with Juice Defender free and 52hrs with XP8000

Haven't flashed it yet as phone is only 10 days old, so giving it sometime and probably wait for 2.3.4 to come out. I know KE7 is meant to give me better battery life, so may do the update or wait for 2.3.4.
My advice just get an external battery pack. My Energizer XP8000 will give me 2-5hrs extra S2 battery run time per 1hr on the charge (basically every 1hr 25-30% charged). So if you're away from home or at work, plug in XP8000 for 1hr and give the S2 a 2-5hr top up charge. But probably quicker to charge on S2 AC adaptor as USB = ~450mah and AC = ~650mah. So on AC every 1hr on charge = 40% top up on S2 battery life.
The added bonus of XP8000 is it has tips for 1000s of devices, so i can use it for my Acer 3810T notebook too which gets 10hrs itself and XP8000 can give it an extra 4 1/2hrs on top.
One thing I notice is I'm getting better battery life after each successive charge, with Juice Defender free started out around 17-19hrs, then 19-20hrs and now 23-26hrs. Been charging off XP800 @450mah for past 4 charges maybe it conditions battery batter than AC @650mah ?

A phone and a PDA (so called smartphone) are two different animals.
I forgot to say that my 3 years old HTC Polaris (with Windows Mobile 6 and a 2.8 inch LCD display) had about 12-14% battery discharge in the same conditions (but the battery was smaller, like 1300 mAh). Just for comparison for those who believe that Android is at fault.

[Q] Mini Pro getting hot with fast battery drain on ICS

Like the title says:
I use the stock rom and after the Update on ICS i noticed my phone is getting really hot even when im not using it. I tried using advanced task killer to close app running in the background and i also close every app i use in ics multitasking... its draining battery very fast! 40 % in 30 minutes. Its not warm the whole time just sometimes it gets warm and drains battery... dont know what to do :/

I had same thing using google maps with gps (as car navigation) but this is the only case. Idle it acts normal.
Taskiller self can take very much battery and make phone hoter. I really dont see + for using them. You need just check battery menu which app take so much battery and then we can help you more.

Taskkiller itself is not running in background. i use it sometimes to look which app are running in background and to kill the ones i dont need. The problem is the battery status is looking normal. Display 33% phone 19% and some other apps do also drain battery.... but the problem is its only getting warm when i dont use it. sometimes when its laying on my desk i pick it up and notice this. when i look at my battery then its sometimes 20% less then 10 minutes before when i checked facebook for example. for me this must be something with the firmware or not? or some hardware defect?
maybe take it to a mobile service
Did you make wipe after ICS update? Maybe its a bad configuration after the update.
Also, you can try CPU Spy in Google Play and tell us if phone is on state "deep sleep" (when you lock the phone, it should enter this state where battery drain is minimal).
Make screenshot of Battery Usage screen and post it here.
Then install BetterBatteryStats, use it for few days, then make screenshots(Partial Wakelocks, Alarms and Processes) and post these here.
I have the same problem, but I know it comes from the Exchange service. Sometime it becomes crazy and drain the battery + heat the phone.
For now, I just have disabled my Exchange account... Not really a good solution.
I have found others thread talking about this problem on other phones (all with ICS), but found no answer.
I did not made any wipe, nor before, nor after the update (from stock GB to stock ICS).
It's not very helping, I fear...
just a few senteces about my day:
The battery was loading untill 7:15 today then i went to school; my phone in silence mode and i used it for 4-5 whatsapp messeges and maybe 3 facebook checks and 1 or 2 instagram checks.
it got hot a few times again and its on 34% now. really bad i would say. on gingerbread i had like 60-80% after a half day in school with much more use.
Now i looked what drained Battery. in ics i cant take screenshot so i just write it down:
40% Facebook Calendar Sync
19% Display
10% Phone
8% STandby
6% WLAN
5% Android Core Apps
4% Facebook
4% Android OS
2% Android System
This is the first time i look at the battery drain seeing that Calendar Sync is taking so much Battery. I still believe it could be something else because before it was nearly the same without calendar sync and display on first place.
So for now i think im going for a wipe, hoping it will be better then.
i will share my experience with you asap. :good:
woah, 40% on that FB crap?
also, the system standby usage seems a bit large also.
try to wipe it, maybe flash some other ROM and see if it helped you.
a healthy battery usage would have display at 70% or so, phonecalls 15%, then all the rest.
depends on your usage tho.
but something is definetly wrong with your phone.
you said that the problem occured after you updated it,
so i think the hardware is out of the question (if the phone worked normal before the update), i'd definetly flash something there, the stock rom is useless anyways..
there are very good roms even if you have locked BL, check kamarush and the new CyanogenTimescape rom also.
keep us updated about ur problem
Cheers!

you must root first, then copy the rom to SD, reboot in CWM, and install from there. it's pretty straightforward from there on just make sure you select "locked bootloader" when prompted.
After the update from gb to ics I didn't notice a much higher battery drain. I use it like on gb and on my feelings battery lifetime stays equal to gb. I have got an unlocked bootloader but still on stock rom using rage kernel ics 3.2.

Soooo. I looke up what have drained my battery and it seems that the Xperia Facebook sync (The stock sync thats buildin in the normal firmware) have drained the battery. on GB everything worked fine. Now i deactivated the sync and the battery life is much better. It seems that my phone also stopped getting hot. But for me GB still had a better battery life. Today i woke up at 7 am (germany) and played Football Manager a few times between the lessons and in a free lesson so im at 16% battery now (should be ok because the football manager drains a lot of battery) and battery usage shows:
64% display
16% FMH 2012 (football manager)
7% Android System
5% Mobilfunk-Standby
4% Facebook
etc etc etc.
looks normal for me :good:
guys my battery life is fine now but i have freezes now... if i use my phone for whatsapp it sometimes just completely freezes. no chance to see a reaktion for any button any ideas wtf is going on there?
Battery drain that you've encountered is definitely not normal. I get about 3 days on ICS, and think that is what you should be getting as well. Crappy FB application is either bugged or broken, because you're not the first one that got their battery drained by FB calendar sync. My advice would be to remove FB calendar sync service, or disable it somehow, if you're not using it.

On the xmp with ics you have xperia facebook. its a facebook calendar, contacts etc sync by sony. This was the app draining my battery. i disabled it and now i have like 1 1/2 day battery with normal usage.
And for my problem with the freezes. i removed all bloatware i could but my phone is not rooted. i was thinking about rooting but i'm kinda new to the xmp roms and its hard to find ics ones that are working perfectly. before i had an lg p990 and i was using cm7.2. it was working like a charm.
i know how to root the xmp i saw some tutorials but im still not convinced

Phone battery draining quickly after JB update

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

Hey Kaigo ,
I have faced the same problem as you have faced ... Gone through a lot of problems to fix this Many of the Stock JB's for GS2 are having a lot of issues with the battery drainage
Well I had found a solution to this problem You can try installing the JB France update (XEF) & the UAE update (XSG)
It worked pretty well for me Try it and let me know if it worked for you

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?
Thanks for the help so far everyone! :laugh:

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.
Sent from...this is not even my S2
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.

[Q] 1) Upgraded from 2.3.3 to 4.1.2 by Samsung. 2) Battery hates me. 3) :( :( :(

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
5) Read about jb settings/issues.
Sent from the little guy
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?

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.
