battery drains completely in less than 12 hours

On Galaxy S I9000.....what can I do to fix it? This happens even with minimal usage.

Which rom?

2.3.4 Gingerbread xxjvp

try to overcharge your phone and see if there still any battery drainage!

I have same "problem". It will be fixed when there's been few batterycycles.

I've only had this rom for 1 day.

I have this issue on Darky 10.1 (2.6 kernel), 2.3.3
Battery lasts around 10 hours with light to medium usage (its a new original Samsung battery as well).
Does anyone have any quick advice to fix this? Bit under time pressure due to job at the moment and don't have much time to research this. Any advice to fix this easily and quickly?

I had this problem after switching on the “Vorabruf über Mobilnetz“ in the Cache-Settings of Google Maps. Maps was closed, but battery was fast going down. Using XWJVH.

I too have almost the same problem with Darky Rom 10.1 - but I've heard that it has been fixed in the new beta version. I'm gonna flash it at the end of the week and after a few days of observing, I'm gonna tell you the results.

It's been through quite a few cycles.

I think I figured it out.....I think it was Skype. If you sign in the app is always on...it doesn't have an exit feature. There is, however, an app to close it. I used it and got normal battery life today!
We'll see if it keeps working like it should.

So I've upgraded to 2.3.4, (Ficeto.Deodexed.XXJVP) and Android OS battery drain stopped. Now it shows 70% battery usage on display (before it was 70% android OS). I recommend updating your system too

with darky on medium use never had more than 14 hrs )

I've given up for the moment and gone back to Darkys 9.5
Now at least I can get through one whole day and have about 40% left

Are you willing to flash the rom again? or you can try to use the speedmod 15g t11 for the kernel to replace the JVP kernel.

it's said that when you use the USB connection to your PC, you need to reboot it. So this battery drainage will not happen.
In the ROm 2.3.3 JV5 and JV6 for Asia, I do the same to keep the batter alive.

Try backing up everything and then factory reset phone. Generally this happens because of a few unwanted applications excessively using ur processor, in turn draining battery or there may be a malware that stealthily connects itself to the net. This will almost certainly cure the disease. If it doesn't, then there is a serious defect in ur hardware or some of ur system app required for properfunctioning of the phone is corrupted, causing excess pressure on the processor

It is a big problem to everyone, I charge twice per day for this.

Calibrate your battery
Let the battery go down to 0% and turn off
Then turn the phone on, it'll turn itself off again cause battery is low
Keep doing this until its totally 0%
Plug in the charger, charge it to 100%
Turn the phone on
Download SGS Tools from the android market place
Run the app
Go to "scripts"
click delete battery stats
Unplug charger & you're done
battery should be more stable now
go to settings
applications
running services
check what you have in the background
close them down if they're unecessary
I get through the workday with only 10% loss

If you have an really old SIM card, try and replace it with a brand new one. This may also help. I had bad battery run time with two LG Optimus 2x phones (about 10 hours) and not so stellar 20 hours with the i9000. Finally I stumbled over some advise to replace old SIM cards. Since mine was over 12 years old, I ordered a new one. It is not gonna change the world, I know, but it was worth a try .

Plz DO COMMENT if u HAVE/HAD ABNORMAL BATTERY-LIFE..!!

hey guys i m having abnormal battery health...
battery ends in an hour..
nd it turns off in a very strange manner .. it nvr goes 0% wen it shuts down.. it turns off drctly from 80% or 50% ..
so i think it is a hardware problem.. may be it is d battery.. but i hav to b sure.. coz my battery warranty is not anymore but the handset warranty is..
PS: removing battery stats via cwm dsnt give me any notification.. it that ok?? or that means it s not wrking..

try to wipe battery stats with titanium backup or some other program (needs root i think) then fully charge and calibrate with battery calibration.hope it helps

DDJP4 is even poor... within 1-2 hrs after charging my phone and keeping it idle also makes batt level fall to 80%.. backup is hardly 10-12 huous.. battery calibration app did not help also but it actually work on other ROMs.. completely lost with this batt issue for moths now.. actually lleft with no hope........... :'(

try with kyrilos or sumee rom !!

Undervolting works wonders.

same with me fon suddenly switch off between 80 to 50 % battery and darining very fast during 3g or even 2g data on. it goes from 100% to switch of within 20 minuts, i think it is not hardware problem

switch to 2g and you solve that problem

thnk u guys fr ur cncern.. but i trd them all.. none worked...

i trd stock roms.. used old roms & kernels (coz wen i used them , there was no problem) .. but the problem is still there.. i m quite sure it s abt sumthing hardware.. jst dunno if it is battery or handset.. :/

i too have bad battery life , my phone only last 12hr max in idle mode when it is connected to 3g , i have tried battery calibration and other roms but they give me the same results .

Well, i'd suggest go for a new battery and try...coz 20mins battery life is not even possible when i had 1400MHz Performance, 2G connection always ON, then also i got around 10-12 hours...

I've got this battery draining issue too. :-\
I have it when the data connection is on. But when it's off, the battery drain is comparatively lesser.

umm actly with ur latest kernel 3-4hours with most minimal usage... oced to 1000mhz..

See if the battery is showing signs of heating.
I would also suggest, try it with another battery (U would be lucky if you have someone else nearby using SG3 whose battery you can try to check).
Normally, battery draining is not so much, especially on Stock ROMs with no over-clocking, other things remaining constant, especially since its a 1500 power batter.
Let us know what you did eventually.

Bro you did not mention if there is over heating in the battery?
Its very strange bro, i hope you are not overclocking your processor perpetually. you may try and for sometime, set cpu profile to something like 200-600 Mhz if using GMOd or 67-667 MHz if using Fugumod.
If its in guarantee period, then flash a stock ROM and give the phone to service centre, they would repair for free (as this type of issue may also happen with motherboard problem which is covered under warranty).
I am actually confused because, with the info provided, it can not be 100% ascertained if its really battery problem

[Q] Do you have battery problems with SwiftDroid RC5?

Hi! I wanted to know if you guys have a problem with the battery life on SwiftDroid RC5. I have a poor battery life and therefore big battery problems.

i had mine and bought a new batt no probs after that

Yes, I do. Since RC4 and RC5 I have very poor battery life. Before it was enough to charge once every other day, now I have to do it daily.
Actually after installing RC5 it was a disaster as battery didn't keep even 24 hours but after recalibration it's better. But even then during the course of the day while doing basically nothing (say, sending and receiving 3 or 4 sms) it goes down from 99% to 40%.
Edit: I should mention that I overclocked to 800MHz, but I used to do it before RC4.

Same here. I'm moving on Cyanogenmod 6.

yeah swiftdroid is a real battery drainer but
on swiftdroid on average my battery lasted 2 days..
but still i use cyan6!!
good in battery and performance!!

Same here. Experiencing battery problems on SwiftDroid aswell. Like mentioned above the battery drains even when doing nothing. Experience this on basically any mod built on SwifDroid ofcourse. Changed to EleganceSwift, waiting for mike to release AOSP with Bluetooth-free radio ;-)

There's something more to it.
Recently I was playing a bit with my phone, installed couple of applications and then suddenly I realized that battery doesn't drain as fast as it used to. One thing I noted is that for example Videos application doesn't reside in memory anymore. I'm not saying this one was the sole battery hog but I'm starting to suspect that those cases of battery going down very fast may be related to some misbehaving app or apps and not necessarily be Gingerbread's fault.
If that's the case, the solution would be, I imagine, to trim system preferences to have such apps killed fast not to let them stay active.

using ASIS atm, but when I was using RC5 I didn't notice much faster draining. Still, it depends how many apps are running on your device and did you overclock it? I used to have min 250MHz, max 600MHz and it was pretty fine with texting, multiple apps running and music. Now with min 825MHz/max 825MHz it's draining faster ofc

Well,I remember a day when i update to SwiftDroid RC5, the batter drains and there isnt any app running in background after that i changed to a another rom.
btw fdespotovski, Multiverse is my favorite rom, in fact, i wrote on the offcial blog but i have problems with the RC3, statusbar sound widget doesnt work properly for now im on RC2

I'm not using ASIS, still at RC5, and what I reported is that both RC5 and RC4 drain battery much faster than earlier versions. Assuming ASIS is just cosmetic change to RC5 it doesn't surprise me you didn't notice any difference. And again, I do overclock to 800MHz and I do it since M5 if memory serves me well. I know principles of overclocking and I know, and accept, drawbacks that come with it. But when at the same clock RC3 can live two days or more while sometimes RC5 barely manages only one then I suspect something is not right.
I tried to check which applications are responsible for battery drain but system report is not helping when telling that 98% took Android system, 2% cell standby and 2% phone idle.

Sorry for necroposting but I didn't want to litter forum with new thread and the problem itself hasn't go away.
I'm still using SwiftDroid v2.0 RC5 and until recently I still had problem of battery barely keeping one day: whole night on the charger and after moderate to no use during the day on the evening it was almost drained.
Recently I installed one more application (rather unrelated, I'd need really solid proof that CPU Spy directly improves energy usage) and after that the battery easily keeps for two days. Which brings back the theory I have that the short battery life is not necessarily caused by Android itself but by some applications staying in memory and not sleeping properly. If so, installing extra app may help just for this reason that it having higher priority will swap out those misbehaving ones.
Thus I propose little hunt, if anyone's interested. I'd like to stay focused on v2.0 RC5 (maybe RC4/ASIS if you believe the difference is not too big). I need reported both GOOD and BAD battery life. In either case please write down all apps currently in memory (you can skip those you have installed, I'm mostly interested in what comes from ROM). And don't forget to mention which actual version do you use and whether it's good or bad case.
Given some meaningful data I hope to isolate which apps cause excessive battery drainage. I'm not sure what to do with that information next but I think it would be good start anyway.
To make said start, here's what I have:
SwiftDroid 2.0 RC5 / GOOD battery
- DSP Manager
- Usage Timelines Free
- Doit.im
- K-9 Mail
- Auto Memory Manager
- Superuser
- Settings
- TM World Clock
- Go launcher EX (doesn't report itself as staying in memory but I suppose it has to be running somewhere)

custom roms...with gingerbread will definately have faster battery usage!! u cant help it
---------- Post added at 10:33 PM ---------- Previous post was at 10:31 PM ----------
use stock roms.... if u want good battery life!

Guys help please, I have a battery/charging problem after installing RC5, this is my first ever custom ROM, it worked great yesterday, but after charging it over night I'm stuck at 99% it won't go up nor down, the phone won't charge and it won't even connect to PC via USB I tried turning it off completely and then plugged in the charger but it just booted up (is it supposed to do that this is my first android?) and that was it. Everything else works fine, wifi etc.... Is there a way to fix this ? I can't transfer a new custom rom to the sd when it won't connect to the PC

the battery stuck at 99 % is a often coming bug and i don't know any solutions mine goes to 97 % ...
ehen phone is shut down and you plug the charger its normal that its booting(because of fastboot)
connection to pc should work, try another port re-install the drivers

thanks ...............

I also have a battery problem... i have installed this ROM 3 days ago, and now i can't charge my battery over 45-55%. Phone was charging all night long, and batter lasted for a day and a half, but its annoying... btw, what now, do I delete battstats now at 55%, when i can not charge phone to 100%?

LG GT540 battery drain very fast

I have LG GT540 with android 2.3.4 cyanogen and the battery is just getting drain to fast ( its new battery) .when i go to battery use i saids that android system use 99-100% of battery waht its not normal ( my friend has about 7-8% use) and she last for 1-1.5 hours with normal work ,in idle about 4 hours till battery drops dead. Phone is getting to hot , i tryed to put others 2.3.7 and its same again what sholud i do.
solution i tryed: wipe battery stats -didnt help
going from 2.3.4 to 2.3.7 -didn help
PM me to see pic cuz i am new here so i cant post outside links at the moment.

Did you wipe data when updating to 2.3.7? If not, try it (maybe also without restoring stuff from backup, if wiping+restore does not help)

yes i always wipe data/cache/dalvik cache so tahts not issue,can i format SD card is she a problem maybe?

yeah same for me i am also using a rather new battery

The battery level stays on some percentages longer than others.

First of all swiftdroids battery is only supposed to last 1 day.. so use a differnet rom. Secondly check that ur CPU is on ondemand not performance .. cause sometimes u get the rom like that.

what worked for me
Hi
I wanted to thank for Zoe Rom on its thread, but i cant write on developer's threads yet (altough i clicked thanks button there).
Im glad i finally got rid of my memory hogging default rom and now i have a properly working phone again!
Also i wanted to reply there (to some people also complaining about battery endurance on GT540 on Zoe Rom) how i fixed my battery main problem.
Pic of current battery drain:
http://postimage.org/image/d8o8uusd7/
As you can see i am aproximatelly at 50% battery after 1day and 11h of not charging.
I had 2 problems:
1- Battery lasted aproximatelly 5 hours on standby (and i mean i wouldnt even touch the phone and the battery was gonne after that time)
2- During intense battery drain usage, the battery was reporting to have less energy than what it actually has.
1st problem solved by simply turning off the wireless after im done with using it. No idea how could that be taking away so much energy, but it was. Somewhere during the period i was using my default rom i got used to have wireless always on, and my battery on the later times was going away faster than normal (i also like to listen to music on the phone). At the time i didnt correlate the 2 things, and i just put in my head that it probably was the battery dieing on me. It wasnt! The wireless (i suppose because of the Sync function also being on) has been draining my battery like mad between charges.
2nd problem persists. As you can see on the pic, those 2 spikes down correspond 2 diferent aproximatelly 1 GB file wireless transfers with Wifi File Browser app. This transfers (PC->Phone) make the phone CPU have to unzip the two 1GB files to the SD, so they are very CPU and SD card read/write intensive (i can force this battery drops with other instense battery use like playing a 3D game for example). The thing is if during that temporarly drop on the battery level measurement, the level hits 5%, the phone will shutdown. But to be honest, this problem is minor comparing to the 1st one.
There is one other minor problem with my battery, wich is the reading being inconsistent (drops 10%, then gains 15% then drops 5% again etc), but is this a problem at all?
I read a post of a guy that had made extensive testing to his battery cycles, providing loads of graph of battery levels (cant find link) . I didnt read through all of it, but i remember the guy saying something in the end like "Dont be too paranoid with your battery levels, as they arent accurate. Instead use your phone normally and you will gain an idea of how long will it last with certain types of usage"
By the way, he also said for people to just charge their battery whenever they could/wanted as it has no negative impact on battery life. I also read a bit of a paper on lithium-ion batteries stating the same, so no more forcing full-discharges for me!
One last thing! Deleting the batterystats file is as simple as disconnecting your phone from the charger.Why? because that file serves solely the purpose of suplying the UI with info of the battery drain usage on the current battery cycle.
http://www.xda-developers.com/android/google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
And you can confirm this if you unplug your phone while looking at yout battery stats.
I hope this helps
PS: pls notice that it could have been not the wireless itself that causes the battery drain, but some service using the wireless. Finding this would require more extensive testing.

Some people says that this does not work, but it worked for me. This procedure extended m battery life from 5h to 2 days..

Update
Hello again
I just wanted to give an update on the situation since i noticed this post is linked from the Zoe Rom thread.
Two days ago i bought a new battery, an unbranded one (cost me 15€ here in Portugal). The shop had a legit LG battery for 37.50€ but i tought it wasnt worth the money. This battery has the same specs as the original, except it is 1300mAh compared to the 1500mAh of the original.
I dont have any battery related problem any more. Yesterday i woke up (100% battery), unplugged the phone, let the wireless on all morning, listened to 2-3 hours worth of tunes, browsed the web a bit, tested some messaging apps etc. Today i woke up, didnt charge during the night, and im sitting on 45% battery. Wish i had gotten a new battery sooner lol
With my old battery the phone wouldnt shutdown. It would always automatically restart. I had no ideia a malfunctioning battery could cause this.

I've have had similar problems with the battery on my GT540 with all cyanogenmods - 2.3.7, 4.0.4, 4.1.2. There were no such problems with original 2.1 I think it is the price for the newer versions, I can live with that, I don't have to buy new phone

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!
