Battery discharging vs not charging

When my Galaxy Nexus GSM is not plugged in, the battery shows itself as "discharging". Previously this used to be "not charging". I have tried multiple (Jelly Bean) ROMs, different cables, wall and USB chargers. Same problem. The larger issue: my PC no longer recognizes my phone and I have resorted to using AirDroid to transfer files.
Can anyone shed light on this issue?
I have done full wipes, including wiping battery stats.

Mine was always discharging...
And make sure that you got fast charge off if you have that on. That disables MTP capability.

I have exactly the same problem...see my thread...its recent!

I had a similar issue, and then not long after the phone refused to charge. I had to take it to get serviced, and the ended up giving me a refurb instead.

I think it has to do with the temp of the battery, if its too hot and you have it plugged in it will say discharging.

First, don't use a charger other than the original. The different volts mess with the NFC chip and antenna. Try disabling NFC and rebooting. Leave NFC off and try to charge. If that doesn't do it I have another option that might work but I'm CDMA so you would have an extra step to change lines in file.

Thanks for the suggestions, guys. I tried disabling NFC but it had no effect. My phone is the international version (the box was in Polish) which is not warrantied through Samsung USA, so I guess I'm out of luck there as well. I'm just gonna hang in there until the next Nexus phone, I guess.

When will people realize that the difference in voltage won't cause any problems with the phone as long as they're within safe range.
I've been using the charger that came with my G2 (htc) on my nexus for months and have no problems. I would've continued using the original one that came with the nexus but it had an annoying whine to it.

Really because it sure seemed to be my problem a while back and anytime i use a different one. Guess samsung and google must not know what theyre talking about.

Chargers are rarely the problem, however different usb cables might be the problem instead.

New glitch spotted when phone is of and in the charger it wil chrage for like 2 seconds and then the animation saays the phone is full!but 2seconda later its charging again so on and so on... sort of chargingloop..
But it never charges

Am using samr original charger and cord. Works fine

I have this same issue
My Galaxy Nexus from Verizon has worked flawlessly for several months now. It updated about 4 days ago to JellyBean 4.1.1 and I have been charging the same two wall chargers, car charger, and USB cables every day since I got the phone. I even was using the USB charger to deploy and debug a simple application I am building around noon today. This evening at about 8 PM while on the wall charger I noticed the charging stopped. No lightening bolt icon, status says Discharging, and I noticed one time that it said Not Charging. Neither of the wall chargers work, nor is it recognized by the laptop using the USB cable. It is at 65% charge and is dropping fast. It seems that no one has a fix for this other than replace the phone.
Very difficult for me to believe that the USB port just went bad using the same chargers every day. Hard to blame JellyBean that has run at least 4 days with no issue even though several sites point to a possible charging issue. I even dialed *#*#4636#*#* and checked the battery status, and it's health was good. I have not rooted or placed anything on this phone that is obscure beyond my simple near "hello world" development apps. I have rebooted, and performed a battery pull with no such luck. With the number of posts pointing to a JellyBean issue, and users experiencing the same issue after the upgrade to 4.1.1 I am leaning towards this being a software issue, but it is interesting at the number of posts saying that the their only fix is a refurb phone replacement from the carrier.
Pretty odd occurrence, and extremely frustrating. As I said the phone worked fine all day today. This just started a few hours ago for me.

OK I have fixed my issue. and it does appear to have been hardware related. I will preface this with you must be very careful not to break your phone with the solution below. I read several posts about using contact cleaner on the USB port, so I looked at the port on the phone and noticed that the "toungue" inside the reciever USB port appeared to be slightly bent down. With the phone off and battery removed I used a needle to wedge under the toungue and bend it up ever so slightly making sure I would not break it. Pluged in the phone and it still did not charge. (That was last night) this morning with the phone at 55% and thinking it was going to need to go back to Verizion I did it again phone off and battery removed only this time a bit more forcefully out of desperation. I definitely moved the "toungue" up and even had a bit of difficulty getting the USB cord to slide back into the connector. But when it did the Phone is charging again. Appearantly I must of jammed the plug into the phone upside down last night when getting into my car and bent the "tongue" in the USB port. Lesson learned, and hope this helps others.

Means the battery has been recharged and discharged to the point were it holds less of the charge. Basically its an older battery, or its been tappered with with, probably a rom using to much ram or pussing the device a bit too far nightly and ported roms could be the cause I say stick to stock kernal unless you really now what to do
Scrap that wrong fourm I think

[Q] GSM Galaxy Nexus not charging

Hi Guys,
Before I start, I have read many threads (I think all) relating to this problem and I have googled, googled and googled.
My Device:
GSM Galaxy Nexus
Problem:
It won't charge. No matter if turned on or off. The battery stays always at 0% and when taking a look at *#*#4636#*#* it says "charging".
What I have tried:
- Bought three different batteries.
- Tried two different cables, incl. the OEM one.
- Tried two different wall chargers.
- Replaced the Micro USB port.
- Wiped, reset etc. the phone.
- Tried different ROMs and Kernels. (Yes, I am desperate).
Any advice what the problem might be?
Thanks in advance!

could be the pins not making proper contract with the battery

They look all the same. Not bent, not damaged, not dirty.

hmmm that is really all I can think of..
The fact that it says charging leads me to believe it isn't the port (like most people experience)

I have plugged my phone into my computer. It says "not charging" now. This message appears after a few minutes when I turn it on. Same happens when I plug it into the wall.
Now it's getting really strange. I didn't observe this behavior before.
Before I changed the Micro USB port, the message was >always< "not charging".
Now, after the change, it says for 2 minutes "charging" and then it changes to "not charging".

Did you replace the whole USB board as well, or just the port? It sounds like the USB board is bad.

Hi lowandbehold,
No, I replaced the whole board if we mean the same. I can't post links at this time because I am a new member of XDA, but you can search for "Dock Connector Charging Port with Flex Cable For Samsung Galaxy Nexus i9250" on eBay.
UPDATE: Plugged it back into the wall. It says "charging AC" now and does NOT change to "not charging". Funnily enough, the voltage keeps dropping. From 2040 mV to 1961 mV in two minutes.

i'd say replace the device.

Unfortunately I'm having the exact same problem. I just replaced charging port literally just now and it still won't charge. It says "Charging" but it's not charging. In the Settings it says discharging.
Could it be the battery? I'm thinking of buying a new one and seeing if that works.

Has anyone found a solution to this yet? with mine it charged fine in the beginning, and then it would only charge to about 86%, and then 84%...then 80%...currently it will only charge to 14%. I can leave it plugged in for 48 hours and it says it is charging but will not go past 14%. it takes a few hours for it to charge from 0% to 14%, but then dies within 30 minutes of EXTREMELY LIGHT use.
I've tried two different batteries which both yield the same results. I have en external battery charger and can charge the battery to full (according to the light on the charger) and place it in the phone and the phone will tell me it is at 14% or 8% or something like that (which makes me believe it has nothing to do with the usb port).
I have explored everything I could think of on the software side. The problem started on Ice Cream Sandwhich, it didn't stop when it was updated to Jelly Bean, I recently rooted it and have tried a few different roms including stock roms and CM10. I tried battery calibration apps.
So far nothing has made a difference. Any Ideas?

Nope no solution has been found. I'm just selling the device (and telling them the problem, so far I'm selling it for $275 and people want it) and I'm going to buy an SIII or a One X

well, this really sucks...it seems that a few unlucky people (like me) have this charing issue...
I too changed my USB flex cable thinking that this was the cause, but nothing changed
the battery icon says charging, but the system says discharging
what a major p*** off, cuz I'm fed up of changing batteries all the time, I have 5 batteries
I hope that someone will be able to figure this one out, cuz its a real brain buster

Any update on this? My phone bought in July is also just started giving this problem. When it is on it simply will not charge. All these months I was using another charger with no issues. I have tried the following:
1. Using the stock charger
2. Bending upwards the male connector in the USB socket.
3. Removing the battery overnight
Nothing seems to work. When off, the phone seems to charge somewhat and charging icon comes on. But charging when off for about 5 hours resulted in battery showing about 50% (from 13%) but it drains very quickly. Sometimes when charging for 30 minutes (when off) and switching it on it shows 100% battery, but then still discharges very quickly. Sometimes it shows very low battery.
Also my notification LED is glowing red since about a month, even when phone is switched off. If I remove the battery and connect the charger, the LED starts glowing red - blinking, so it seems the USB port is providing power as sometimes the battery does show 50% and seems to last a bit from there.
What are my options here? I am on the latest JB OTA update which came around 14/15 Nov. In India, I will get no service from Samsung for the Nexus.
I am going to try a factory reset first and then next see if I can get another battery. And maybe I should return / cancel the Nexus 4 I ordered?

Maybe try wiping battery stats in recovery? I was having similar issues today with "not charging". I was plugged in to the wall with nothing, so I plugged into the computer... ADB enabled and device was connected as a media device. I booted recovery and wiped dalvick and battery stats, rebooted and now it is charging via usb and AC. Don't know what happened, but it worked for me. Hope it helps!

Thanks for the response. Well, I just tried draining out the battery (it took almost 2 days lol) till it would show shutdown warning soon after booting up and then removed the battery and held down the power button. I then charged it in 'off' mode for a few hours, I think overnight. I used the actual Nexus charger instead of the generic one I was using all this while. When I turned it on, there was about 40% charge showing.
There was another JB update which I managed to complete (leaving it on the charger). The phone seemed to work fine, but did not show a charging state, but suddenly the next day on its own when I just plugged in the charger, it showed the 'bolt' charging icon and since then it has been working perfectly.
Simply no clue as to how and why it started working fine. Probably the previous 14 Nov update had some bug which was resolved in the latest update or the latest update reset the battery stats or whatever.
I am more worried about my upcoming Nexus 4 which has a non-removable battery as to what I would do if something like this happens.

I can 100% guarantee you that wiping battery stats had nothing to do with it.

[Q] Captivate Glide battery draining issue?

Within a second my Captivate Glide will suddenly go to 0% power then slowly charge back up over time..or if I charge it, it jumps back up to about where it left off. And it happens pretty much every time I turn my phone on for more then 5 mins. It seems to happen while sending or receiving text? Any ideas what could be causing this or a solution?
I keep my data off, and theres 3 apps (Stock SMS Messenger, Handcent SMS, and the Contacts+ App) that can handle SMS on my phone, and I have locker pro that displays my notifications. And I also use the Nova Launcher, but thats the only app's I keep running. Maybe a conflict with the apps or a bug with one of the apps? I don't see how that'd effect the battery that much but possibly?
I've also changed my ROM a few times, but right now I'm back on the newest ICS update and I've rooted it. Maybe I need to change it again? I can't remember if this problem started happening before I did my last change.
Or maybe just a bad battery? I don't know much about batteries but I haven't had this phone long, I don't think it'd be the battery.
If you have any more questions feel free to ask and I appreciate any help!

I had about the same problem, with it working fine with a decent charge (anywhere between 30-80%), and all of the sudden it would say "battery critically low" and shut down. Putting it on the charger would often get the charge to show what it was before it freaked out.
I noticed that the battery was starting to bulge and get somewhat "mushy"....which told me the battery was probably going to explode or leak if I didn't replace it soon
I have had the phone for a year and four days, and this just showed up in the last few days...fortunately I bought an extended warranty and they will pay for the replacement battery I just picked up today.
FYI, the battery should be totally flat on both sides. Mine would wobble if I set it on a table.

Ok, TL1170, Thanks!
I already narrowed it down to my battery by the time you posted that because I factory reset my phone multiple times and changed the ROM once to see if that'd help, and it didn't..I was running out of stuff to blame it on ..
But yeah, my battery is pretty badly deformed and I just ordered a new one.

Thanks, mine is doing the same thing - about once every 2 days or so. I can see in the battery life plot that it sometimes goes from 90% almost completely vertically to 0% and then right back up to 90%. I don't see any obvious bulges or "mushiness" to it, but it doesn't seem to be completely flat when put on a table. I'll see if I can get a replacement battery, this phone was not used by it's previous owner for maybe a year or so before I bought it, maybe that might have been part of the problem.

Any time a battery is misshaped it can do the oddest things.

Pull out and visually inspect your battery. If there are any visible cracks or bulges, dispose of it carefully. Damaged lithium ion batteries are incredibly dangerous; a properly pissed off LIon will produce a sizable fireball.
If your battery looks fine, fully charge it (until your phone says "100%" or "Charged"), then fully discharge it (don't connect to the charger again until your phone shuts off for lack of power). This is to calibrate the charge estimator chip in the battery itself. Don't bother with batterystats.bin, it's completely unrelated.
If the above doesn't work, you need a new battery. If the new battery behaves the same way, you need a new phone

Happening to us too
It's been happening to my phone for a while now, but I'm usually using it while at a desk so I can keep it charging. However, it just started happening to my wife's Captivate Glide also. I checked my battery and don't notice any bulging or non-flatness... but it happens about once or twice a day now - Pretty much anytime I do anything more than make a call with the battery indicator saying it's somewhere less than maybe 90% charged. I've taken to using a portable backup battery when I'm out.
If you view the battery usage screens, you can see the cliffs where it drops from 80-90% down to zero and right back up. We've only had them for about a year, so I'm going to take it to AT&T and see if they can do anything for it... probably not.

If you're really desperate to get those particular batteries working, you could try cleaning the contacts, both on the battery and in the phone, with rubbing alcohol and Q-tips. But most likely you will need new batteries.

Battery( low power) Shut Down Issue Fixed
I also was having the "critical powerl level" shut down issue over the past two weeks. My phone is about two years old, and there was a few occasions in the past two weeks where i pulled it out of my pocket and it was off. Then this past week the phone (on a full charge) would go anywhere from around 90% sometimes %40, and then all of a sudden say "battery low" and shut off. It would turn back on, but would only stay on for a few minutes.And a few times it also got really hot. It wasnt doing this when plugged into the wall so i examined my battery and there was NO visible flaws or bulging of any kind, it looked fine. But as we all know just because it looks good certainly doesnt mean it is so i odered one on ebay for about $10. It arrived 2-3 days later and instantly fixed my problem. The phone is fine now and hasnt done anything wierd. It was the battery. These batteries have a limited life span, and very often the phone may say the battery is 76% charged but the capacity of the battery under load can still draw it down to 0%. You cant always trust the level the phone says its at. So if anyone else out there is having this power issue it really isnt expensive to find a good battery out there. The one i got was $9.98 and it is a Samsung battery identical to the one that came with the phone. Except the new one has a fresh date of 2013 on it. Very happy to have my phone back. Ive never been a part of any sites like this, but im posting here now because there seems to be a lot of people having this issue, and often someone will put a very complex procedure on these sites to fix an issue when its not always necessary. If you have the power/shut off issue like i've described here and your phone does the same as mine was its probably the battery, and for the price of a new one like i got, its worth trying.

charging issue

is there anyone with problems charging the t320?
it goes fine until 40%, above that or stops charging or is really slow, like 1% in one hour.
i thought it was a rom issue, so i flashed the original rom from sammobile
the charging at this moment is 56%, 150mA average, when isn't negative - 200
this is stock usb and charger, and also with other charger/cable is the same

Me too

I was just searching the forums as bought mine yesterday and have a similar problem, mine got to 56% then stopped charging. If i turn off the tablet it does start to charge again so will fully charge with it powered down and see what happens.

soon i'll be testing another charger
you can see the charging voltage on the galaxy charging current available on playstore
most likely i will use warranty

Pop the back off gently and disconnect the battery from the main board. When you reconnect it, let it charge up fully before turning it back on. After this, it will behave normally for the rest of time.

Thanks

Thanks for the reply but it seems my issue was caused by a faulty outlet socket. The socket works fine for everything else but would only charge the tablet when it was powered down. Tried charging off my laptop and desktop usb and it was the same, but tried some other outlet sockets and they charge fine. I understand the usb outlets might not provide enough to charge the tablet but hadn't considered the socket as I know it works, must be just enough high resistance to prevent it charging a working tablet but provides enough current to charge it when it's powered down. The fact it was showing a 56% charge was just co-incidence.
Thought it might be worth posting this as it's not something I've come across before.

Here's the thing. When mine was misbehaving I could get it to start charging again by switching outlets or even reversing polarity on the wall plug. It was a temporary fix as within days the problem would be back. I thought I had it fixed so many times. It always came back. If it happens to you again just remember the above post. It's been four months since I did it and never once has it been quirky. Something in the hardware needed reset that only disconnecting the battery could do.

It's the faux leather thing you pry off. Keep the angle that you pull on the cover shallow and work it slowly.

with no other solution i did too pop the back off gently and disconnect the battery from the main board, now it's working OK, let's see how long

cabel pull
hoping this works. I just filled out a warranty email today for same issue on 12.2 Tab Pro. It pried the case open with a credit card. Very slow, took about 7 minutes. Pulling the power cable in the middle, probably behind green tape. Use needle nose pliers or something small behind the wires and pull up. The pins are tiny and will f*ck the whole thing up if bent.
I get the feeling that the screen turns itself on even when eye tracking settings are off or closed in case. I hear the annoying sound at night when charging. Why Sammy does not have a smart current sensor built in is insane. Asking you to unplug when most people will leave on and charge overnight. Just dumb.
I can't get past 57% charging for last 2 weeks. Stock, unrooted for first time in a long time, so I am pissed to hear ROM had not effect. This is likely undocumented hardware issue Sammy doesn't want to admit to.

even on my T325 I had the same problem but I solved it this way ...
I have worn the battery completely until turn off my device, I loaded the battery overnight to device OFF.
wipe and install rom custom samsung
I launched and used app "battery calibraton" (root)
I have now done 4 cycles of charging to 1600/1750 mA

There is no need for physical interventions on the hardware, maybe someone does not know in depth the behavior of lithium ions

Perhaps not, but I and MANY others have encountered the same problem. Across multiple Roms, fully discharging and recharging, running the so called calibration apps. Rebooting, unpluggin, replugging. The problem NEVER fully went away. It would work for a charge cycle or two or three, then would reappear.
I finally took the back off, unplugged and replugged the connector., closed up the case, charged it for several hours before turning it back on.
Not ONCE has the problem occurred since that intervention. That was over a month ago.
Maybe it's not lithium ion behavior, it might be in the charging circuit and hardware.
If you have a suggestion, then by all means share it so others can solve their problem.

I've already written how I solved the problem, but in 5 years and dozens of Android rom installed on various devices, this problem for me was very frequent.
Always the same. On my ST325 I solved like other times in the past.
No news I found on this battery, battery charger of the same problems since I know Android

sorry for my bad English ...
for this device I've tried all the roms available (CM11 or not)
the problem is very acute especially after CM11> Pro Plus V2, but the problems had already occurred some time with the various installations buil CM11
about a week I did the operation described above (already done in the past even on my previous samsung device, Note 1, Galaxy s4, Galaxy Mega, Galaxy tab 3 g3 ) with the same result ...
The battery charges very quickly with the device ON to 1700 mA (monitored with "Monitor battery widgwt pro")
again sorry for my english

Battery Issues

Okay I've had my galaxy S3 for some years now. Randomly I started to have a problem with my battery. It started dying faster and faster. After that a new problem popped up where it would only charge up to a certain point, around 35-50% and then stop. Now i did try many things and i feel like theres is nothing left to try. Im not sure if this is a software or hardware issue as i couldnt figure out the problem. I have tried changer the wall adapter, usb cable, and batteries (all official samsung ones). I even got an external battery charger and charged the batteries there and put them back in my phone. What i noticed is even a full charge on the external battery charger would show as a 35-50% same as when it charges and stops charging through usb. The magic number i noticed is 37% for all batteries, chargers, cables. Slowly this started changing and now it no longer charges properly at all. when plugged into the charger the battery drains completely to 0% on charger and if left overnight will jump to 100%. this 100% doesnt last long however and the cycle continues. Sometimes the phone will die and i plug it to charge and it will be at the 35-50% spot. The only thing i wasnt able to do was test with another s3 as everyone i know is S4 and higher. Any help would be appreciated as upgrading is not an option right now financially.

Need more information. ROM/TouchWiz version, have you tried wiping? clean install? etc.

When the problem first started i was on a custom rom but this was a while back so i dont remember the actual name of the rom. I was running that rom for months brfore the problem started so i doubt it was a rom issue. After dealing with the battery issue for a while i started to get annoyed. So i unrooted and reflashed stock firmware hoping it would help but it didnt. I ran stock for a while. After that i decided to try flashing a custom rom again to see if it would help. Currently im running TMS3KK 3.1 TW 4.4.2 and the problem is still there. I have tried factory resets, wiping everything and even battery calibration apps but nothing seems to help. My battery indicator can go from 100% to 12% just by unplugging the charger. Sometimes my phone would die and den turn back on with like 40% or so. Really can tfigure this out i feel like it might be a hardware issue. Also is *#0228# command useful?

I have the same problem. Try using rubbing alcohol and toothbrush to clean out the USB port. Also take a look at this link to remove corrosion from the port.
http://www.instructables.com/id/How-to-fix-a-slow-charging-android-smartphone-enh/?ALLSTEPS

I dont think its a port issue as an external battery charger doesnt seem to fix the problem either. Problem seems to be with the phone not reading the right percentage.

I used Kies 3 to reload the firmware to KOT49H.T999VVLUFNH2. Battery is more stable now.

Yea i tried flashing back to stock as well but unfortunately didnt help me.
