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.

This may sound stupid but works
Charge it to 100% wipe the battery stats let it drain out then recharge it to 100 let it drain out again and then carry on as normal i do this before and after each rom and clear the stats etc before releasing each softmod my battery lasts on average 2-3days thats texting and 4-7 phone calls maybe abit of radio and checking email 4-5 times

I did that many times but without success ,my battery is dead with 1-2 hours of use

1-2 is realy extrime, try wiping data and see how long it last without anything installed. If it still 1-2, there is hardver problem.
Hot phone can be inditcator of cpu or motherboard problem. :-\

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

lg gt 540 battery
Hi
I ve got LG GT OPTIMUS 540 android version- 2.1 and i have the same problem. If i dont use my phone batery can be dead in 5 hrs but if i use it 2-3hrs...my phone battery usage says android system eats 95%...is it norm or bad?
The topic pretty much explains it. I've been using different modified stock roms and now I'm on the latest nightly of CM7, and I keep having this issue. After a reboot at around 50%, the battery drops to 15%. The weird part is that while I continue to use the phone, it slowly rises back up to sometimes 30% and then starts going back down. I've always cleared battery stats when flashing and calibrated (which I believe is unnecessary), but I don't know if this is a problem with the battery, the phone, or if anyone else is having the same issue?
Attached is a screenshot of battery usage. You can see I never actually charged the phone.

anyway guys, you need to recalibrate your battery, its not being read accuracy.
download BatteryCalibration from the market, charge your phone till 100% (not just 100% but when it beeps, that its truely at 100%), then use BatteryCalibration to calibrate your battery, and then drain it to 0.. (crank full brightness, turn on LED flashlight, blast internet radio, whatever makes it drain faster to get this part overwith), then recharge it to max.
so;
charge to full 100%
while still plugged in, run BatteryCalibration
discharge to 0%
recharge to 100%
battery successfully calibrated, you will now have an accurate reading
I had exactly the same issue on 3 different custom roms....finally resolved by going bck to stock rom

i have the same problem when i use custom roms.
i have been using pure stock rom by wannam but rooted for the past week with 12 hours aday syncing and surfing the net and plenty of voice calls via viber and my battery lasts at least 16 to 18 hours.
right now i am using odexed KL3 Kernel KL2Base KL1modem 2.3.6 and it is absolutely amazing interms of battery life and performance.

This thing only happens on CM7 for me. It had 40% before reboot and like 15% after. However mine only increased to about 17% then started dropping as usual. This never happened on any stock ROMs I've tried(stock, not themed/modded stock).

did you
did you rsolve the problem ? how? I have the same problem and I tried more stock roms ... I don't know what tot do ....
Its nothing to do with calibration etc, its just how the fuel gauge chip works, it learns and more accurately reports usage over time. For example, if you reboot and (I can't remember the actual voltages for the S2) you have 1200mV, the chip goes, "ah, that is 15% battery." Then as you use it more, it relearns its settings and goes "aaah, my mistake 1200mV is really 30% battery. I'll display that instead."
Its been covered frequently that "calibrating" the battery of the S2 in any way but actually using it, is next to useless.

I installed Batery Callibration in my Galaxy Note .. Love this app...... Increase so much my life battery
One question: How often I Calibrate My Battery??
1. After flash or update ROM.
2. When replace or pull out & put in battery for whatever reasons.
3. I do calibration about once a week.
I always drain battery till it is 1% before plug in charger after hit the calibration button.
Battery time is acceptable to me...15+ hrs with normal use (stock ICS rooted).
Thank you very much for the tips. I Have Rocket Room V07 and Speedmod kernel 3.3. With 3g and Wifi turn on all day, my battery last 24 hs.....Very good for me

Never. That app does NOTHING. You have fallen victim to the placebo effect.
Wiping battery stats does NOTHING on any Android device other than change the behavior of Settings->Battery. It does nothing with regards to fuel gauge calibration.
The fuel gauge chipset in our device does not require calibration and calibration techniques cannot be applied to it. (With one exception - resetting it after a reboot on low battery can have a temporary positive effect - but you can just wait a few hours for it to converge.)

Battery Calibration, try following the procedure stated therein and verify by yourself if it works.
At least you have nothing to lose but very poor battery performance.
You guys should have ever heard of an alternative battery product named MUGEN that selling original and extra sized batteries world wide including range of Galaxy batteries. They also supply a battery calibration app on Play Store regardless phone models but it's for rooted phone only. If this app does nothing they wouldn't bother wasting their time developing it.
Another thing is to investigate what apps or services prevent your phone from going into deep sleep, also try freezing apps or services you aren't using.
Those are my tricks for having battery performance improved.

Hi can i have the link for the calibration app ???
Search battery calibration on google play...its free
Your phone had to be root to use battery calibration
i dont trust any battery callibration app or battery power saving app
i only used cpu spy and betterbatterystats
my point is check ur device, does it goes to deepsleep everytime screen turned off. if it doesnt check using bbs what apps making ur device turned on/wake ur device. im very satisfied with this method. 1x full charge for 24 hr for my daily use and only 24 % battery drained for 24 hr if u didnt use ur device at all(standby)

I have samsung galaxy s2 just over a month or so and i have big problems, due to battery. I know this is common issue on this device.
Until now i try to recalibrate battery like that, no hard reset. The phone it;s new and it had ICS 4.04 installed on the first place.
1) drain all of your battery untill phone shuts down
2) turn on and drain battery until phone shuts down ( repeat until you are unable to turn the phone on- this step is very important because we need to drain the battery competely)
3) take the battery out and wait 5 seconds or so and put it back in
4) Charge the battery while the phone is off
5) when the charge is 100%, take the charger off then charge again to get 100% again
6) turn on your phone and enjoy your new battery
Once i try to take the battery out after charge, and wait over 2 minutes. I know this is a common issue of s2, but i have some screens, maby someone had similar problem.

Next, i'll try Battery Calibration (can't post the link, new user) tool from the market / wait for Jelly Bean official update. Then hard reset. Next step: service.

The batteries in these phones can't be calibrated per se. Just use it normally for a bit. The peaks and troughs in your battery graph are because you're clearing the fuel gauge data. Mine would drop from the 73% I'm on now, to about 14% if I cleared the fuel gauge chip data, until it relearnt its settings. Just charge normally and use it for a few days, it will sort itself out.
If not, new battery.

Im having the same problem. Tried swapping batteries with another S2, recalibrating the battery and even installed another rom, same problem persists. The phone will auto switch off after a few hours of not using (overnight especially), and batter will drain like mad when it happens. Brought the phone back to samsung for repair now.
Same here...

I'm currently having the same (really annoying) problem. My international GS2 is less than a month old and uses the latest official firmware on ICS. It happens almost daily -- or should I say nightly? The phone has at least 60-70% of battery left by the time a go to sleep. When I wake up in the morning, it's completely depleted. My stats look exactly as in the screen-shots in the first post. I'm always charging/using it "normally" but it hasn't sorted itself out.
I don't really know how to solve this and it's frustrating. The Internet has mixed "feelings" about the solution(s)... However, same as with my battery issue, I'm looking for something more stable and reliable.
Am I missing something? Does anyone know the exact cause and how to fix it?
Hello, I took the phone to a local service (pointed by Samsung from my country) and they replaced my motherboard and another pice of hardware....something in the recharging sistem, i dont know details. I think there is a "lot' of bad motherboards... people form the service call it a generic name.
In conclusion, the problem was the motherboard, not battery. I have recovered the device from service one day ago, if i'll experience any problems... i'll get back with details.

Hi,
I saw many folks are facing similar problems, but my problem is little different. Now a days whenever I play Candy Crush my S4's battery drains out very quickly i.e. 60-70% in the span of 5 - 10 minutes, also it gets charged up with equally fast (about 80 % in 10 min). My phone is just 3 months old...earlier there was no such problem. I haven't installed any new apps in between. Is it the problem with the battery or with the handset?
Any help will be greatly appreciated!!
Thanks
The battery drain in almost time cause of software problems
But charging too fast Im saying it could problem with the battery it self

It's because from what I remember, battery callibration is not regulated at rom level. It's a chip inside the battery.
For example:
With the old HTC Desire you could wipe battery stats in the recovery.
For the Samsung Galaxy S2 this didn't have any effect because the chip inside the battery regulated the calibration.
From what I remember it's the same for the S4. If the calibration does not work (eg charging to 100%, taking the battery out, putting it back in, recharge again till 100%) then his battery is faulty. So unless he messed his rom up seriously, no wipe or other rom will help. His OS just reads the data from the chip.

Thanks Guys... most of you were absolutely right... I took my S4 to the service center and it was found that it was the problem with the battery... it got deformed as well... I got it replaced now... You guys are great ... Thanks once again.
