[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%

Humm.. Strange..! U sure the other battery dsnt got any prob??
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..
Sent from my GT-I5800 using Tapatalk

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?

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.

[Q] 6hrs and the battery is dead

hi!
im on ARHD 3.6.4 , my phone battery used to drain more then usual but still i managed to work with it.
this morning i think i broke a record while my battery last only 6hrs!!!
i changed only two things this morning.
1. i installed battery calibration app and when my battery was on 100% i ran the program to wipe my battery stats file.
2. i installed mighty text to text sms from my computer and not my phone..
any chance doing one of these two caused the prob?
any help will be great!
thanks!

after calibration it takes a few days for the battery to settle. So wait a few days and battery will be better

I think it's a kernel problem, I switched to the Bricked kernel and back to normal now. There was a problem with the phone staying awake. I killed my first battery in six hours too and that was using Juice Defender also!

Yep kernel problem. Mentioned a million times on the arhd thread. Best bet is bricked kernel for now. No more issues since

i restored 6.3.3 and resolve this issue until confirmed new and good version of a ARHD

I was also using ARHD with Faux kernel.
The battery was really back and would be under 80% after a couple of hours of doing nothing!
Flashed the Bricked kernel and no problems now. Battery is great!

i understand but as much as i saw from other posts around the forum is that
faux kernel is something which is working better with ARHD , it uses all it tweaked and stuff..
is bricked kernel will work good with ARHD? if so why mike doesnt post his rom with bricked also?
there must be a reason

yea i was also in the 5 hour battery life boatt. but im using coredroid 2.5 and was using fauxs kernell. Faux definatly knows what hes doin and is a very respectable dev, he helped my g2x feel like i didnt get soo ripped off by buying itt lol butt yea i listened to everyones advice and switched to bricked and so far my battery is alot better, i fell asleep with out plugging it in to charge and i woke up with 75 percent, i fell asleep with it at 78..... fauxz kernel is great but it does hav some battery guzzling bug

Check out guide in my singature.. It will solve your battery problems in no worires

well i just installed the new ARHD with the new faux kernel and the battery is back to normal.
still getting dead fast but not in 6 hrs
so i guess it was rom / kernel issue and not something from my phone.
im 4 hrs without a charger and im on 80 percent so i think im good.

well , sorry to update that my phone battery keep getting drained fast.
i cant finish a working day.

[Q]Battery Problem

Recently i bought a new battery for my ace plus as the old one overcharged while using usb tethering stuck at 100 for hours and then turned off my phone. After recharging it normaly the battery life was reduced greatly.
The problem with the new one is that when it completes charging after 2 hours which is normal it stays at 99% for quite a time while using it and after that it drops 1% every 2-3 minutes if im using it to browse or play games. It takes 1.5 to 2 hours gaming to turn off a fully charged battery now. The 99 stuck thing is normal ?
Calibrating and deleting battery stats didnt help.

vickyg, I've also experiencing the same issues,
I have done battery calibration several times and tried juice defender, from 5-8 hours of battery life with average usage, my battery only improved to 12-13 hour battery life,
I've figured out that, the problems wasn't with the custom ROM or stock ROM. :silly:
I've dig some research and found that it may* due certain hardware problems, not sure
(going to sent my ace plus to samsung center soon)

[Q] Is it battery or ROM or Kernel issue ?

Hi,
My phone is almost not charging full or it doesn't show as such.
This is detailed breakup of my issue :
I put phone at charging exactly at 2pm at 2%
3pm it was at 36%
4pm it was 54%
5pm it was at 64%
6pm it was at 73%
7pm it was at 82%
7:30pm it was at 84%
after this I removed phone from charging and rebooted it. Surprisingly it showed 100%.
Battery doesn't last more than 12hrs no matter what I do. I am using Greenify too.
BT, GPS, Auto-Sync, 3G, etc all are off. WiFi On 24hrs.
Screen-off battery drain is also around 8-9% per hour.
Can I do/try something on software side before I order a new battery ?
Right now I am on Carbon ROM (20131008) with stock kernel, 1512, Ondemand, SIO, No OC. Its same on every ROM I tried except seemingly on ARHD 7.3 (used it less than 24hrs. Its rock solid and smooth.)
I would greatly appreciate any help/advice !

I also has this issue still looking for the solution
Sent from my HTC Sensation using XDA Premium 4 mobile app

the battery misreading while charging is a common htc's fault after rooting and there is no solution yet
i have the same thing while charging my device
but the difference is i don't have that fast drain
how old is your battery?
did you try a different battery?
make sure it fits correctly to the pins

Battery is just 1yr old. Yup I checked the pins. They are correctly fit.

this is a rom issue i think as this has also happened to many people and and this happens after many days on a single rom (and u make the rom unstable)
the solution is simple just backup ur data and full wipe and flash rom again and u will be good to do for next many days (if u keep the rom stable)

I flash ROM almost every alternative day and I always do Full-Wipe

Battery Kernel issue
I am new to xda. I actually flashed a new rom after that phone doesn't charge after switching off. Could it be a kernel issue or the rom's issue. I have a Canvas HD. And sorry if this is not the place to ask the question. I couldn't find any other thread related to this. Please help.

Similar issue here. My charging often stops at about 80%, but after a reboot the battery's full charged.
My battery also gets drained very fast, but it's about 2,5 years old so that's probably the problem.
With the CPU clock speed @1,5GHz and the GPU @266MHz i get about 15h +/-2h of battery life.
I keep battery saving ON most of the time. Bluetooth, GPS, 3G etc all OFF. WiFi ON for about 1-2h per day (if i would keep it on longer, my phone would be dead in 4-5h).
I'm using ViperS 5.2.1 right now (full wiped before install). I got the same experience on ARHD and previous ViperS versions.
Tested the charger - it's fine.
I was wondering if anybody else got an old battery like mine and how long does it last on full charge

Hi guys,
I have a HTC Sensation XE that i bought three days ago (second hand) and i have the same problem with the battery % not reading correctly.
Now this is what i observed:
- the charging is very slow - from 20% to 40% in 2-3 hours
- after 2-3 hours of charging if i reboot the phone the charging LED turns green and the battery reading says 100%.
(i tested to see if actually it got charged to 100% and it did, i turned everything on, watched a HD movie, played some games and after 5-6 hours of playing with it i still had 50%)
- tested the battery to see how fast it drains from 10% to shut down and it went on at full brightness and everything on for about an hour and something so this means there might not be any problems with the battery
- so the reading is wrong because the battery is charged after a few hours.
- i did a test to see if the same thing happens when the phone is off and i left it to charge for 2-3 hours and when i got back the charging LED was still orange. When i started the phone the LED went off and back on as green. The battery was 100% charged.
- If the same behavior happens in off mode it means it's not a ROM problem (by the way from what i know the phone is stock, the guy never did the rooting.....that's what he told me - can't know for sure).
- from my electronics background it seems the phone updates the battery information sometime at boottime. When charging, the software keeps the charging LED on because it's supposed to charge due to incorrect data but the hardware charging controller drops the charge current because the the battery is full. So this can be an incorrect sensor reading by the software or an incorrect feedback given by the hardware controller.
So what do you think, what can cause this.
Should i try rooting the device?
And i tried factory reset from android and factory reset from bootloader and the problem is still there.

Ok so i did the following:
- unlock the bootloader
- flashed CWM
- installed superuser
- wipe battery stats
- wipe device
- calibrate battery with an application from market
The problem is still there.
I figured that when in bootloader first thing you can read is the S-ON/S-OFF. Before doing the unlock it was "LOCKED" and after "UNLOCKED".
I did a relock and the status changed to "RELOCKED" so this means the guy that had the phone before me didn't root which again means the theory that says this problem occurs when the user tries to root the device is not true because it seems the behavior is observed on an unrooted device.
I will dig deeper maybe i find more ideas on what i can do.
I'm running out of software options so this is pointing at something hardware.
I'll get back with updates when i find something else.

probably it is htc's bug
the same happened to me after rooting the device

For now I will try to make some full cycles of the battery and see if anything changes. I usually use the phone at work and by the time I get home it's almost empty. Plug to charger and till morning it's full with a green light. I will have to monitor the charging times and get back with results.
Sent from my HTC Sensation XE with Beats Audio Z715e using XDA Free mobile app

Well i did some full charging cycles and nothing changed, still the same long charge time(read by the phone) and with restart it bounces to 100%.
I had the original Android 4.0.3 with Htc Sense 3.6 at the time. Got 4EXT recovery and an 4.0.4 rom with Htc Sense 4.1. Did a full wipe and battery stats , installed the new 4.0.4 rom but the problem persists.
At this point i think the battery is the problem so the next thing to do is to change it. I will get back after i change it, hopefully sometime in november.

After a long time I managed to change the battery and after a few tests it seems the problem is still there. The time on battery improved as I expected but everything else is the same which means it's something hardware defective in the phone. Also did some tests with android 5.1 and the same results. Meantime I sold the phone and got a Samsung Galaxy S3 Neo. Hope this research gives some answers to someone at some point. Cheers.

[Q] phone sometimes dies when using camera with flash

Sometimes when i use the camera with flash and the battery is low my phone just dies.
But on other occasions it might work perfect.
I bought a new battery 2 months ago and i am running ViperS 5.2.1
Does somebody know a solution?

make sure your battery fits correctly

The new battery is a very tight fit
although thanks for the answer!

I have the same problem. When battery is under 40%. I have tried CM11 and Carbon roms too, but same problem. A half solution is to underclock cpu to 1.2 GHz (tested on my phone, it dies when battery is under 30%), clean the battery and board contacts. BTW my battery is old, so for me, maybe that's the problem.

Does your phone always crash when the battery is under 30% ?
If this is the case you should try to take a photo when you are charging the phone.
If it works when you are charging you might need another battery.

I have tried right now to take a picture with flash on at battery level 22%. Rom: latest Carbon. It just died. Tried to take a picture with phone carghing from usb, it died. So, i think i'm gonna need a new battery.
