[Q] Bad battery drain, new SGS, tried everything

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...

hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once

will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc

As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .

[Q]Battery indicator showing wrong?

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance

Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?

have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug

After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.

Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic

I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

[Q] Extreme battery drain

I am experiencing an extreme battery drain with ALL the roms i tried.
The battery lasts maximally 5h, with 20-40mins of 3g browsing.
Currently at 38%, display max brightness, 2h 12mins usage,78% in battery use / Opera Mobile usage 22 m
ins, 9% in battery use.
13h since last recharge (i went to sleep).
Also my battery magically charges itself while on standby, up to 4% per hour.
Im pretty sure my battery is calibrated, even if it isnt it would give me the same power.
Also it heats up to 59c (even when i wasnt on 1.2GHz kernel)

I think u need a new batt. Same thing was happening with the iphone and untill i've replaced the bat the same thing happened.

.
Thought so.
Will flash stock 2.3.5 or should i flash 2.3.3, which is the latest official for my network?
I think it doesnt matter...
Well the guys in the service are a$$es so it will take them about 2 weeks for it...

i'm not sure tere is such thing as stock 2.3.5 and i think only MIUI has this. Last is 2.3.4 but i might be wrong.

There is xxjvs that is a 2.3.5 firmware

No your battery isnt wrecked neither magic took place its just that ypur battery stats are messed up!
Fixing them-fully recharge your battery until it shows 100% then switch your phone off and then let it charge for another 1 minute then go to recovery mode( you have cwm recovery right?) Then go to advamced then delete battery stats from their and reboot your phone ! Then for best result ypu can fully drain your battery to nil unt it switches off! Your battery stats should be now fully fixed ! Dont worry for deleting battery stats system will make them again in a few minutes or on a reboot !

[Q] Battery drained too fast on ICS_4.0.3_MR1-RC4.2_I9000

Hi all. From 2 days im using ICS_4.0.3_MR1-RC4.2_I9000 and everything is ok (without gmail and android market). But today, after 100% full charge, my battery down for 2 hours whit 50% ?!? What can be the problem, who drained my battery ? =)

Unless you believe the internet has powers of clairvoyance.... No one can tell you this except yourself. Look at your phone battery stats, whats draining it. Also kernels can be the issue, though more often than not its a rouge app.

Now i chek the stats, 60% used from display!? Before 2 days all was normal. And now 1% per minute, its not normal.

Battery Percentage reduced to 25%

Hi
My Nexus One just completed one year by this july.
And my problem is that My battery switches OFF at 23% battery.
That is, when it reaches around 23% it suddenly show 0% and switches off.
similarly when i charge the battery after around 75+ % it suddenly jumps to 100% percent and says charging completed.
I tried manually deleting the battery stats file.
I tried the Battery Calibration tool.
I tried charging the mobile to 100% as soon as its starts to shut down.
But still the same issue.
Is there a way to calibrate it or do i need to buy a new one ?
My rom : OxygeN1mod
I am getting around 6 to 8 hours if i use Gprs or wifi.
Another query :
in ebay.in 3200mAH battery is 9800 INR which is too high for me ( i bought my mobile for 14000 INR)
1400mAH battery is 2400 INR.
So is it better to buy a spare 14oomAH battery or a 3200 Battery ?
Please help me.
THanks in advance

Any one , please help

Tha'ts not normal if it's shut down at 25% ! ! !
Normally at 10%
Should buy à New One
If you don't care about the design of your n1. I suggest you the 3200 one

I heard that you can't fully charge the battery while the phone is running, it has too leave room since the battery is in use at the same time it's charging so it wont overcharge and ruin the battery.
So I was recommended to shut the phone off once in a while to charge the phone to full 100%.
Mine is now starting to die at around 20% but when new it died around 10%, newer lower.
But then again the battery could just be going bad.

Install de battery calibrator (for nexus one) search in the google play
Verify the field "battery age" and set to 100%
Reboot and give a full charge
Drain normaly the battery, and look the percentage of the shutdown
If your phone shutdown on the 15%, set the battery age to 85% (100%-15%)
If dont work try:
