Sgs3 charging problem (takes too long charging) - Galaxy S III Q&A, Help & Troubleshooting

Hello.
Recently I started to have a weird problem with my Sgs3. It takes way too long to charge. And when I say too long is like, I go to bed at 1am with 9% battery and it charges all the night and at 8 am when I wake up was at 85%, just happened today these stats.
The problem I have noticed is, back when it has no problems charging it just goes into deep sleep to charge and usually was good in about 2 to 3 hours. Now, every time I charge my cell phone never goes to sleep, in the battery screen just appears it as active (with screen off) all night long when I plugged it into the charger. And there's the problem, some days it just charges normally and others I get this problem. Been trying to know if is something I do to make this problem but I just can't find it and I need help. I wiped dalvik cache, hard reset, everything and still the same.
I'm using última rom 9.0.1 (same problem with 10.1 and 11,I just like 9.0.1 better so I put it back) with siyah kernel oc 1.6ghz.
There's an screen of my battery. Notice its active with screen off and was charging ok, and suddenly just started to charge wayyyyy to slow, happening tons of time this.
I'm sorry if this is a duplicate post, I searched for a problem like mine and didn't founded, just ppl with no charges at all.
Thanks for your time in advance

As you've got Siyah, try setting the charge current up a notch.
CyanogenModded Very China-like, from my Samsung Galaxy S III
LG Familyguy59/Beatsleigher

looks stupid, but, samsung original cable seems to be bad for charging, the opposite, only samsung cables are good for data transfer, try to charge with another cable (I use a sony one) luck

In general it looks like indeed Samsung's cables aren't well-made and after some time they're losing some "power".
Luckily we have an international USB standard (micro usb?) for SGS3 so you can try really different chargers, from cameras, other phones, headphones etc.

Sometimes the issue is with the charging port also. Like, if I use a multi-plug or an extension board then my SGS3 also charges very slowly, even if there's no other device connected on multi-plug or extension board. You can still try Galaxy Charging Current app from Google Play Store and check your phone's charging current when you're charging your phone. It should be near 1000mA as that is the stock value.
Hit Thanks if I deserve it :good:

Also, it maybe possible that since you are on a custom rom and not all customs roms are stable. So, it might be possible that with your rom, there may be some bug which isn't letting your phone go to deep sleep mode properly when it's charging. Try reflashing stock rom & kernel to rule out software as your problem.

well I have the same problem...
this night from 15% goes to 35% - 8h charging

I can't remember what I did to solve the problem but I remember I solved it lol. Anyway I don't have s3 anymore... I hope you managed to solve it. And ain't broken charger for sure because I used the same s3 charger on my s4 and no problems.

[Q] Xperia turning off... and off... and off

Hi, I got a very annoying problem.
Since a few weeks ago, flashed a ROM and when I've tried to use the phone, it keeps turning off randomly, sometimes after a few minutes, sometimes after hours. So, I tried to take it back to the clean original 2.3.3 ROM, but it keeps happening. ¿Any idea? ¿Any solution? Please, help me.
Oh, something else, it only happens when the phone's used with the battery, when it's attached to my laptop and used as modem, the problem doesn't appear.
I had the same problem, it said android system shutting down. I just bought new battery and it works.

I think, it's the most logical option, but I was trying to get some feedback first. Thanks.
Maybe calibrating the battery.

go back to stock and see if it helps! try to troubleshoot the problem! Also, don't install any apps!
There are instructions on how to calibrate your battery in the first post in this thread:
http://forum.xda-developers.com/showthread.php?t=1489214&highlight=calibrate+battery
If the problem is the battery, you might find that after calibration that the battery drains faster than expected, and still shuts down, only this time it warns you that it's gonna shut down. This would then be the true battery drain. If that is the case, you might just need to buy a new one anaway.
Otherwise, I don't know what else could be causing those symptoms. (Other than an electrical fault, from accumulated damp or something)

thanks so much..............
What happens it's that the phone shuts down suddenly, the message appears for a seconds and it's off. Wait for a few seconds, try to turning on again and sometimes works for some minutes, and sometimes it's keeping turning off, and off, and off. But, the battery level seems to be correct, I mean, when I turn on the phone after one of these sudden shutdowns, only drains the logical ammount of battery for starting use the phone.
I think... if the problem never appears when it's attached to the laptop and charging constantly, and magically appears when I used the phone with the battery, it's probably just a battery issue, right?
I have a similar problem to this, my phone randomly shuts down after showing the 'Android System shutting down' message but sometimes loses ALOT of battery. Last night it went from 78% to 8% after shutting down :/ I noticed it happened more often when im playing games or taking a video, things that take up more battery. When i keep it plugged in it keeps awake so the problem stops but i cant keep it in all day every day. I dont really want to buy a new battery until i really really have to, but I have had the phone and battery since the x10 first came out about 2 years ago, so anyone any other ideas? Thanks

Yeah tried that but it didnt seem to work :/
could it be hardware problem like broke battery or bad connection on motherboard?
Could be pal are u within your warranty (sony (Ericsson) it has a 2 year global warranty but u need to ring ur network provider and ask them to put u through to se
Sent from my X10S using XDA
Yeah this happened to me before about 6 months ago, so i went to my provider (3) and they sent it away to Sony Ericsson and they sent me a whole new phone but I didnt want to do that again really, but i may have to. When im not using WiFi or 3G then it works fine, and when its plugged in to the charger it works so i guess its a case of not usuing the internet when im not near a charger
I have the same problem.
My X10 reboot random when using 3G (Wifi is still OK) and Gaming. Now i'm on Stock 2.3 and stock kernel and....wait. (Flash some ROM and change the new battery....but not solved )
Anyone help us !!! Plizzzzzzzzzzz
Maybe your solution
I had the same problem sometimes with original kernel after 1 year of using my phone.
Then i tried to install a new rom, and i was thinking the problem was solved. But it was not...
I finished by trying the X10S (v7) rom with DoomLord kernel (1113mhz) and this problem was solved...
I tried some kernels and this one was stable with a good battery life and no shutdown problem. With some other kernels i had this problem back.
So I think that kernel could be the problem.
Infortunately, with the rom X10S v8, Doomlord kernel cause issues with wifi (unable to get ip adress). So now i use kCernel-SE-stock-mod-v1 and no shutdown problem anymore.
*Maybe the solution is*
Try to change your kernel with one of thoose :
- kCernel here (in "2. kCernel-SE-stock-mod-v1")
- DoomLord (search fo x10_gb_DooMKernel-v06-1113_wifi.zip)
Note :
- With this two kernels, you'll have to download appropriate wifi patch and install it from SDcard via xRecovery
- don't try to install X10S v8 if your bootloader is locked
So, try to flash your X10 using flashtool with Doomlord kernel
Tell us if it worked, i hope it solved your problem as it do it for me.
voltage
Hi,
I have had this issue too, for the last few months. No matter what ROM/Kernel, batt stats cleared, etc, still the same. Can idle all day, but as soon as I use 3G, GPS, or use any intensive app, she shuts down.
As an experiment I installed a battery monitor that plots graphs of % charge, temp, voltage, etc over time.
I had a close look at my logged graphs and have noticed that just before each reboot, the voltage seems to dip drastically. Battery charge is fine, does not seem to matter. but a sharp drop in voltage occurs. Increased draw for the more complex tasks (3G, GPS, etc) seems to be tripping it up.
As the Battery is now 2 years old, I figured it is just starting to fail? And iv noticed lots of people are suddenly coming out and complaining about this issue.
I just ordered a few new Batteries from 'Ebay', will see how we go!...
peace.
[INFO / SOLUTION] Suddenly shuts off with red LED.
Good to know:
The X10i/a have now reached an age, where battery failures is very common nowadays. Specially if one got the device early on or just after the launch.
Symptoms of a failing battery:
* Device suddenly shuts off, even when the battery have several percent remaining.
* Device drains fast, even when not used.
* Device might just shut off for no whatsoever reason when doing something that draws a lot of power, and will restart just fine.
* Device has a surprisingly fast charge time from empty to full.
When the device shuts off all of a sudden, it's followed by the indicator LED blinking red, rapidly three times, and might repeat this at restart attempts.
Sometimes it takes several tries before the device starts up again. Battery just needed a few minutes/an hour of "rest".
There's nothing wrong with the device.
Just get a fresh replacement battery and it'll work just fine again.
But beware:
There are many fake batteries out on the market, claiming that they have higher capacity, yet very slim in size.
There's a simple rule when it comes to battery capacity:
More capacity = larger in size, which might need a special back-cover. There's no escape from that.
If one would happen to find a such incredible slim battery with super capacity, the battery security circuits and/or chemical makeup probably have been circumvented/changed, and have a high risk of catching fire and/or explode when charging/discharging.
Yeah thanks for all the advice and sharing your problems. My phone does reboot alot when im using 3G or taking a video. Recently my battery would reboot, drop alot of percentage and then increase percentage without charging...magic I dont really want to buy a new battery because my new contract starts in june i think, but maybe il have to. Good luck for everyone else dolving there problems
Also, [email protected], i am on doom kernel and i still get reboots :/

Battery problems after fleshing custom rom

Hello. I got a lot of problems with my battery. It was all fine until i rooted and flsahed a custom rom. I flsahed jellybam and wiped cache data battrey stats and everything before. I get a lot of random shut downs and reboots and battery percentage drops. Sometimes its at for example 80% and i don't use it its in my pocket and it just shuts down. Or it sais it has 30% 40% and i receive a call or sms and it gets to 1% and shuts down and when i turn it on it has again 30 40% or slowly gets to that percentage. I tried aokp, jellybam, rainbow rom (something like that) rootbox and tried dorimanx and siyah kernel. Now i went back to stock rom and krenel but the problems are still there. I attached a pic of my batt stats so pls if anyone knows what could be the problem please help.
Edit: i tried calibrating the battery with an app and manualy shutting down the phone charging the phone to 100% and remove the battery a few minutes but that didn't change a thing

Nice picture, where is that? the Alps?
Sorry for the late reply i had some other stuff going around. I tried resetting the fuel gauge chip with extweeks while on siyah kernel and that didn't change anything, i tried a few more roms and kernels but the problem remains. Now i am on resurection remix 4.0.4 rom with flexy kernel and i tried reseting the fuel gauge chip with xxtweeks and again nothing changed. I guess this is a problem with the phone becouse with different roms/kernels the problem is the samo. Lately its getting worse. The phone is on the table with 80% battery and i just hear the low battery sound and when i unlock it its on 12%, and than goes to 5% and lower and shuts down. After restart it has again around the normal 80% for example. Also one day i charged it to 100% and as soon i unpluged the charger it dropped to 0% and shut down. Could it be the battery or is something seriously wrong with the phone? Thx in advance

Could be the battery.
Just try another battery from which you know it is working in your phone, and then try your 'faulty' battery in a phone from which you know it is working. This way you will know at least if it is the phone or the battery.
Thanks for thr replay. I guess i‘ll just buy a new battery and see how that goes because i don't have a spare s2 and battery to try

I've been experiencing the same problem with my SGS2's battery and noticed that it is getting bloated. I purchased a new one to prevent severe damage on my mobile phone.

[Q][SOLVED] HELP Sudden Battery Drain

This is what happened...
yesterday at 7:00 AM my phone was at 98% Battery
Only Flight mod and Power saver mod was enabled,
Every thing else was disabled
Then i left home without taking my phone ( It was on my bed i forgot to take)
Later i returned home at 2:00 PM
And found my phone very hot.
Now the battery is at 14%
It says 88% of Battery was used for Android OS
Then i turned off my phone
After some time heat went off...
Then i turned on and plugged in for Charging
It Took 4 hours to charge 24% :crying::crying::crying::crying::crying:
Can anyone please explain whats happening ???
It sounds like something is keeping the cpu running, which is why android is is so high and explain the battery loss and heat. You could go into your settings and look at the running apps in applications manager, and see if anything is out of the ordinary.

Could be something like mediascanner scanning the sdcard if you hve one. GSAM and BBS are good apps to check wakelocks. The latter is better but it's a pay for app.

The best app IMHO is BetterBattery Stats. It's not free though, but it's a great asset. I have the widget on my home screen at all times. If you're not in a position to pay for an app, try GSAM, but BBS IS better. This will only be good until you pull the battery though so you need to ensure you check before rebooting. It will show you which apps are keeping the phone awake etc.

Yep. Best way to get good stats is to charge the phone full, unplug it and go about your business. Try not to reboot. At the end of the day lets see those stats and what we can find out.
Here is the list of apps on my Phone...
I don't have many apps...:angel:
I have Flashed my phone just a week ago..
And I haven't got time to restore all my apps again..
So, this is all the apps that i pretty much use now...

I am facing 1st issue as your post what can i do

[Q] Phone keeps shutting itself off, what to do?

Hello everyone,
for a month now my Samsung galaxy S2 has been randomly shutting itself off. It always happens with the same pattern:
The signal suddenly drops to non-exsitent, then nothing reacts and finally everything goes black.​I can maximally use my phone for about 5min but it stays alive for the whole day if I don't touch it.
Also when I switch it on again after it shut itself off a lot of battery life is lost, e.g I have full battery -> it shuts itself off -> I only have 50%.
Do you have any ideas about what I could do?
I thought it might have been a problem with ICS and therefore updated to Jelly Bean but the problem persisted...
Thanks for your help!
Sounds like a power problem. Have you tried a new battery? Could be hardware as you have ruled out software.
I had a similar (not exactly the same) problem on a friends s2. It was on full stock, never been 'messed with'.
To fix that, I flashed NeatROM & a new modem. Now it gets a lot better signal, and doesn't freeze up. It may be a long shot but possibly worth a go.
First though, do what Andrew says :good:
Sent from a galaxy far, far away
I'm currently having very similar issues......I take the phone off charge at 100%, do a little web browsing or make a call / send a text......and then the phone freezes and becomes totally unresponsive....then finally shuts off.
I reboot the phone and the battery percentage shows anything from 2% to 50% remaining. It's NOT the software.....I've changed from stock to cm10 to cm10.1 and reflashed various nandroids without making a difference......
The ONLY thing that stops it happening is to swap out the stock battery for my spare (high capacity 2000mAh) battery....so for me, it's definitely battery related.....
I'm expecting a new one in the post any day now......

Doesn't sound like much fun Keith. Let us know how you go when it comes. It's sounding like a completely different problem to the one I fixed, although it had similar symptoms.

No....not much fun.....but I had this issue with my galaxy W too....so I'm kinda used to it....lol
With the W, I'd get to the stage where the phone would (just about) fully boot.....and then shut down....
Just had a look at the S2s battery and it seems to be swelling which is ANOTHER indication of a borked battery.......

Hope so for your sake! Replacing the battery is a heck of a lot easier than finding a magic fix for a SOD which seems to randomly occur.
A couple weeks back or so there was a guy who's battery connection was sketchy between the battery and contacts, is your connection ok?

Morning Keith. If you swapped out std batt for big boy battery and problem was sorted its gonna be the battery. :thumbup: @ op glad you sorted it
OP here. Swapping the battery did it for me!
(I didn't even notice that my old battery was swollen )
Thanks a lot!

Same problem here, waiting for the new battery to arrive so I can change and test...:fingers-crossed:

Very slow charging i9300

So I woke up seeing my phone was at 58%, odd because I slept like 9 hours straight and my phone was charging during my sleep. So after I woke up I went downstairs, made some food, went back up to see my phone went down to 57% whilst charging.
So I've been doing some troubleshooting. I switched batteries, switched chargers etc. I also downloaded galaxy current charging and found out its only max 100ma, on all the 3 chargers I tried. Not sure if the usb port is jammed, always charged stable, and I can use it while charging without it charging on and off.
Using Archidroid 2.4.3. running boeffla kernel, I tried yank555 kernel too and problem persisted, didnt change any charging settings or something tho.
So how do I fix this?
Unplug charger from plug it again. I used Sony cable.?

The default charging rate is 1100mA so yours is definitely way too low. Flash boeffla kernel again and download boeffla config v2 from the play store. Then go to the miscellaneous tab (last tab) and change AC charge current to 1100 if it isn't already.
Hope this helps!

Just like the guy above, my friend had the same problems and asked me to fix it.
Downloaded Boeffla kernel and set everything up, works like a charm.
Only problem im having is that some chargers still dont seem to work, the phone just dont recognizes them while my Nexus 4 does!
Anyhow, sometimes the kernel settings seem to have reset and need to be set again.
Any chance you can help me out on this one?

I fixed it with changing some settings in my boeffla?.
I turned the unstable charging on

Yeah i forgot to mention, i do use boeffla config app, but all the settings i apply seem to reset on a reboot, like some script is just returning everything to default.
Ive already made a comment on the original kernel thread, hoping for some answers there.
Thanks for your reply tho
Charging is very slowly
I had the same issue..
My I9305 is charging very slow but sometimes it charged very fast
