[Q] Battery drain on Galaxy 3 when on voice call & other battery problems

hello,
i have I5801 galaxy 3..
currently on kies Froyo firmware..
from since flashing to froyo ..
1) whenever i talk on phone (ie do voice call) battery drains out in even less then a hour when fully charged..
2) when kept for charging.. even if battery shows like 10% remaining .. within like a min or two.. battery indicator shows an 100% charged status.
and it drains out in like 10 mins if removed from charging
what i think is somehow froyo is assuming it's charged and is stopping the charging process.
i've rooted it, and tried calibration.. still no luck.. I've deleted batterystats.bin regularly, still a new file is created and no change in battery condition is seen
plz help.. too much frustrated
PS: i am not a pro.. so help plz

don't delete batterystats.bin do some full charge discharge then report.

tried that.. still no change
battery drained off in 30-40 mins..
does ATK make battery drain? somewhere along on some phone someone said that draining battery to nil and charging back cycle makes battery life even shorter.. dunno what to do..

Calibrate your battery after doing a full charge. And use as "normal" for few normal cycles, just like you usually did.

Hi
Try using light version of g3mod kernel instead of oc based.
You can flash your phone with my Rom and test after full battery charge. note some apps are battery drainer like tweetcaster etc due to continuous sync.
Try to stop those services and test your phone thereafter..it will show improvement. .and dont delete any battery calibration seetting once done after you flash thats all.
Do let me know if it not happens.
Cheers.

i flashed g3mod-2.0-nonoc
still when i try to put it to charge..
say currently it shows like 40% charge.. but as soon as i put it on charging (via AC) .. it shoots up directly to 90-100 in two minutes.... this should be wrong, right?
darin rate is also bad
it showed 100% charged and a 3 min call .. made battery level goto 45%

Ok try this .. convert all partition to rfs & flash any stock ROM with stock kernel.. Use Ur phone like that 2-3days.. See if any improvement..

err STOCK kernel means official right?
also how to convert parition to rfs.. is this about partitioning SDcard? coz if it is i've tried using without any card insert .. still same
i was thinking about G3mod 2.0 Beta2 kernel .. heard it uses very less battery..
but i've got a question ( and i can't ask in development forum as per post limitation) that does the 2.0 Beta2 uses less battery than the official samsung jp6 kernel? or should i try flashing that?
(now i may look like stupid asking these question)

first of all, sorry for bumping this after a month..
actually G3 wasnt with me from then, now it's back and problem persists
what i notice is that
1) phone when put to charge, shoots up to 100% in 5-10 mins, even when off
2) and same with the drain, it goes to 1% in 5-10mins
i checked out with battery, and it is fine they(samsung service center) say,..
plz help, i am at question as to what is the reason for this sudden rise and fall of battery level.

if u got a costum rom use battery calibration from the market its free it fix the drains happend whit me to

nope... i had used it before but now i am currently on I5801DDJP6 updated from 2.1 eclair via kies
its stock,unrooted, no modifications..
i'd calibrate battery, but the fact that it shoots up t0 100% in 10 mins
and what i guess is when phone detects 100% battery, it pretty much stops charging after that, thus battery starves ..
can something be done so that it actually gets accurate reading on battery status ?

Switch off your cell...let it full charge....
Then switch on the device and flash the cyanogen mod...
Its fast,stable and also increases the battery power...
had the exact same problem...did that and now works for almost two days...

cyanogenMod site doesnt show Galaxy 3 support...
btw u are saying ROM or kernel?? coz i like stock ROM of samsung as it's easy to use
@bscraze i contacted service center.. they say battery's good and doesn't need replacement...

hey i discharged until phone switched itself off couple of times
and charged it back to 100% while phone was off and then again when ON..
then, i increased brightness,turned on wifi,bluetooh,gps,etc and it dropped to 90% ..
as it is stock rom i think it was between 90-100% (coz with 1% mod)
but as soon as a call came, which was of 2:38 seconds, my phone battery dropped off to 3%
any guesses, why this is happening?

Cm7 is being ported by marcel and still has a few minor bugs and isnt fully working i think thats wjy the cm site doesnt show it. I have about the same problem as you im waiting to get my batt replaced. If it works i suggest you get one too. I'll probably get it nxt wk and I'll report here if theres any difference

what i have been able to detect from last two days is,
that battery fall is severe only when on voice call,
i have been playing music,games without much battery drain
but a mere voice call with everything off (GPS,bluetooh,dataconntection) for not more than 10 mins, drains battery by 20-30%
any ideas about it's reason??

Check out which app uses more battery in battery - settings - usage. That particular process may use more battery than others.
I have a similar problem with my G3 - I'm running CM 6.2
While I checked the OS takes 76% of the battery. I found CM6.2 better in handling FC than 7.1..Or should i just go back to Cm 7.1??
Experts, please advice

Hello everyone. its long since i posted here and thats bcoz of only one reason .. battery problem with my phone. i really was getting pissed off by the issue that i stopped posting here .. cursing my bad old phone.. my battery was lasting near abt 6-10 hrs lately .. finally i decided to..
1. flash eclair (stock) JG6 which came along at the time of my purchase and had reasonable to good batt back up. flashed that and i was like 18-24hrs of batt backup. Used it for almost one week. and as i was surfing thru our threads.. saw some really encouraging post abt Kyrillos 9.3 and its battery backup. so..
2. I flashed kyrillos 9.3 for last 3 days .. and did the calibration on my very first charging after flashing 9.3.. yesterday got almost 36 hrs of batt backup .. right now m on 84%.. unplugged @ 8pm yesterday .. it 10:15am right now in india. so its around 14 hrs .. which i feel is quite good considering my past exp with my battery ..
I dont know what actually has done the trick or its illusion to me . but after flashing eclair my phone performance has gone up smartly.
Using 9.3 NON-OC. with a2sd enabled.
i hope it can help ppl abt our all confusing battery issue .. if not .. at least it can throw some light ...
Press the thanks button if u find it helpful. Hve a gr8 day.

Updated to ICS, lost hours of battery life?

I have updated to the official ICS (AT&T) and now I'm no longer getting much battery life. I had some issues with the update, so I wiped my phone and I have little to no apps.
I used to get 10+ hours of battery life, and now I don't even get 8 idle hours (so now it doesn't even last the work day). I checked Battery Usage after it was down to 20% and cell standby took up 90% of battery life.
I used to run JuiceDefender, but I reinstalled it on ICS.
Why have I lost so much battery life; how can I fix this?

I have noticed the same thing on the stock ICS. Also noticed very slow charge times using USB (possibly true with A/C charging but I am normally asleep when I charge with A/C).
Is this just caused by the bloat that they put in? I want to flash a custom ROM just for battery life at this point.

install sky ics rom , this is the best battery . you can easy use more than 15hours . nexus mod 5.04 is also good . and much easier for noob to install . stock sucks .

Instigator's kernel is for AOSP (CM9/AOKP) so for ICS based official or roms you will need a different one such as mohan's kernel:

As for battery loss, there are some cases where if the flash wasnt done with 100% battery it could be reading the battery wrong and some people have had success with recalibrating their battery (look up battery calibration on play store). Now it was said that it really doesnt do anything for battery improvements and was just for stats use or whatever but for some people it helped their devices read the right battery stats.

how much battery back-up do you get?

how much battery life do you get? I seemed to have very less battery life. Just wanted to know if there is some problem with my battery

Wow. Two battery threads from you. That really makes us want to help you. Not to mention all the details you provide if somebody did want to help you.

ROM: ICS( MIUI ROM). Within 2 hours and 33 minuts the battery level has dropped to 78%. Is it because of the ROM I am using? I have also experienced sudden variations in battery level. When the battery level is somewhere around 60s when i reboot to recovery the battery suddenly drops to below 20s .

That's about right for ics roms and moderate use. I consistently get about 10-12 hours with 1-2 hours of screen on time. Rebooting to recovery screws up the battery readings but you should see it creep up and come back to normal eventually.

Try the Proton kernel if you haven't. I used to get 10-12 hours similar to what you said. Proton improved that for me. Also use Autostarts app or Gemini App Manager to stop apps you don't need from automatically starting.

From what other people have said, inconsistent battery levels on reboot generally means that your battery is on its way out. You can see by using Battery Stats Pro or something similar that the voltage will sometimes drop by 200ma (at least, mine does) on a reboot. Which is why I ordered a new battery... which would have been here last week if it hadn't gotten lost a state away. Stupid Fedex.

I'm running pacman for now and using greenify to keep maps and google services from killing the battery in 5 hours. It went 15 hours the other day but I hardly used it at all. I have another battery but I hardly use it, it's a 1500mah and it doesn't last nearly as long as my good old stock battery which is in fact a bit swollen and slowly dying. I guess that recovery battery thing is like the distant early warning of impending battery death.

Battery life bad even on Anker 1900!!! Help!!

Hi all,
I brought my HTC Sensation z710e about 14 months ago, and I'm a pretty heavy user, so battery life took a hit.
After about 8-9 months i got 4-5 hours screen on time on the stock battery. About 7 hrs heavy usage. I tried formatting the phone, and kept an eye on battery abusive wake locks, but to no avail.
To rectify that I've tried various roms (Elegencia 4, VipersS 1.6, Albinomans CM 10.1) among a few and also tried undervolting the phone. Nothing.
Then about a month ago, I brought a 1900mAh Anker battery which according to a lot of XDA threads is the problem solver for all battery issues.
I've been using that battery with Albinomans rom, and I have tried wiping battery stats to ensure the battery starts from a clean slate, but still I get barely 7 hrs, far from the promised 2days.
That leads me to conclude that something is wrong with my setup. And having tried many roms and kernels, formatting my phone and doing most other stuff suggested on the XDA threads, I cant work out whats wrong.
If it is a hardware issue, is there any way of finding out what it is, and what would be the way to rectify.
Any help would be higly appreciated
(although I've been and rooting and playing around with my phone for abt 3months now, this is my first thread on XDA. It may be a little unorganised in the way its written. If i've left any info out plz let me know. Thanx)

hello, if you use many applications that constantly require the 3G part of your mobile , it is quite normal ...
With my stock battery, i'm about 20hours and more but if i play games for a long time it's normal that battery drops.
I even think that you can be happy that your battery takes 7 hours using it a lot.
Try these CPU settings :
Governor Lazy or Badass
Min : 384Mhz or 432Mhz
Max : uses frequencies between 932 to 1188Mh
When u change ROM try to wipe battery stats before first start
Before u change the Kernel, make a Full Kernel Reset. Flash new Kernel

This part all rings true. You cannot measure the battery life by how long you go between charges. That's almost irrelevant information because if ti's set up properly the phone will use very minimal battery when the screen is off.
The proper way to measure the battery life is by how much screen on time you get plus phone talk time between charges. With an Anker on Albino's CM10.1 ROM that should be 3 to 5 hours depending on a few other things. If that 3 to 5 hours happens all at once, then you'll need to recharge in 3 to 5 hours. If you use it sparingly over 2, 3, or ever 4 days before you've use it for a total of 3 to 5 hours, then it'll last that long between charges.
The 2 things that use the battery are the screen's backlight and the cell radio. Those two things are the battery users. Bluetooth and Wifi are too. But theoretically you're not using bluetooth or wifi unless you are talking on a call or having the screen on. So you can still measure by the scren on plus talk time. And if you use bluetooth and wifi a lot your total use will be closer to 3 hours than 5 hours.

This part is not true. It has no effect on anything. And when you install any ROM the battery stats are going to get wiped anyway because you are replacing the entire contents of the system directory.
No amount of wiping battery stats, calibrating batteries, or any of that mumbo jumbo is going to help. It's all snake oil.
Also keep in mind that you do need to give a new ROM 3 to 5 full charge and discharge cycles before you really see what the battery life is like. If you're jumping from ROM to ROM every day to test battery life you'll never get an honest look at what batter life is like on any of them.

On albino's ROM? You only have 2 options. The one that comes with it, which is perfectly fine. Or SultanKernel, which isn't terribly different. But the install process of sultan gives you more configuration options.

[Q] Heavy battery drain issue - help troubleshoot

Of late, I have been having heavy drain of battery on my Atrix 2. I am running JB 4.1.2 (672.300.404.ME865.Retail.en.05). Trying to troubleshoot it (including recalibration) since the last few days without luck.
The symptoms...
- Sudden shut down - Have had 50%+ charge levels. Goes down to 5% and shuts down within minutes. (You can see the random drops in the charge levels in the pic)
- Completely drained out battery charges from above 40% when plugged in & charges to 100% in no time. (that 67% charge in the attachment is within 5 mimutes of power plug in)
Does the battery need a replacement?

Try changing battery... even i had same problem with Custom rom. Battery used to last only for 10 to 12 hours but now its more than 17 hours on JB 4.1.2 leak,,,,...Use stock rom. and remove any unncessesary apps and installl ROM again if u want :good:

How old is your Atrix 2? If over a year then battery surely begins to give lesser performance. Disable any other task killer / memory manager & just let OS do its thing. See if installing Media Scan disable from play helps & do not keep using random chargers, make use of original charger as received with phone. Finally see Better Battery Stats. It is said battery stats should never be wiped but see if it helps you and finally search for Apex's better battery life guide for many handy tips.
I disabled notifications, sync, froze higher wakelock apps & my battery life improved a bit but then it is no fun existing in a bare bones environment.

The phone is just about a year and half old. The drop in battery performance is just too drastic, sometimes it doesn't even last an hour after the charge. Will try to go back to original ROM and see if it improves else will probably have to go for a new battery pack.

Look like a battery problem to me its not the ROM but anyways turn off location services and wifi they are a big battery drainer
Use 2G when u dont need high speed.......
Try this app called Greenify https://play.google.com/store/apps/details?id=com.oasisfeng.greenify
(it helps to reduce wakelocks and improves your battery life)
:laugh: Let me know if it helped (btw chck your battery and see if its defected they are amny ways to chck it read up the forums )

i have the same problem whit any rom of 4.2. when the custom rom shows 5% i change to stock ics rom an that show me 45%

CM 10.1.3
I couldn't write to developer's forum so I'm asking here.
I've recently firmwared my AT&T A2 CM 10.1.3 and battery drains really fast! The previous build was CM 10.1 (25th of June). I wiped cache and dalvik cache and firmwared CM 10.1.3. At least 3 people report that thie batteries on this ROM drain slow.
What did I do wrong???

Battery life varies so much from user to user that it is impossible to answer your question without A LOT more information.
Go here:
http://forum.xda-developers.com/showthread.php?t=1179809
Download the app and follow the directions in the op. That and reading through that thread itself should tell you everything you need to know about what is using up your battery.
That being said, everyone has different habits and expectations when it comes to their battery. What one person says is good battery life, another will likely say is bad. So just keep in mind that there is not a right or wrong, just what is right or wrong for you.
If I had a dollar for every time I said that, I'd be making money in a very weird way.

Thank you fro your answer. When I used previous version of CM the battery lasted 3 days with minimal using and turning the flight mode at night on.
As long as I installed newer version with JBX kernel the battery lasts 20 hrs max.
