[Q] USB/Battery Charging Bug

Alright XDA, checking if anyone else has got this issue?
Bought the galaxy nexus almost three weeks ago, everything was fine with the phone until last week thursday. My battery was running low so I decide to charge it, only to find that it wasn't charging. I took out the battery and put it back in, still wouldn't charge (or at least it didn't say it was charging). I left it in the charging plug whilst the phone was turned off, hit the power button and the black charging screen comes up. I turn it back on to see that the battery is at 44%, after being at 12% 5 minutes ago.
Anyway, ever since then the phone hasn't been charging right. I plug it into the charger, and it doesn't recognize that its charging, or maybe it actually isn't? It takes a while for it to recognize that it's plugged in, and takes a while to actually start charging. I unplug the phone after it's finished charging and is at 99%, only for the battery icon to display that it is still charging.... it's constantly changing from charging to not charging even though I'm not doing anything.
I got the battery indicator app and that would display that the battery has been discharging since say 1 o clock in the afternoon, yet I took it off the charger at 9 o clock in the morning,
Furthermore, I'm now trying to charge it through my computer and put some music on my phone, but my computer won't even recognize that anything is plugged in even though it is quite clearly charging through the computer. (have had to plug it in and out several times, and sometimes it'll recognize that its there...)
is the USB plug ****ed? should I just send it back? I would go to my provider to get a new one from them as I still have warranty and thing, but they will only accept returns within the first 7 days of purchase. Otherwise that leaves me with sending it to samsung which is my last resort because they'll probably take their sweet time getting the phone back to me and I'm going to leave the UK for 4 weeks next week and I really want to take my nexus with me instead of risking it not coming back before I leave.

Have you tried a different USB cable?

Yes, I've tried the original charger, a blackberry charger, USB cable from original charger through computer, and another micro-usb cable. All have the same problem with recognizing that its plugged in/charging... And now funnily enough it's unplugged from my computer but it's still saying it's connected as a media device.

Don't power up or turn off samsung devices with the USB connected. It messes up the battery stats. I've had the same thing happen to me before on the Nexus S. Since then I learned not to do that on my phones.
I don't know anything about your other charging issues though.
edit: you could always try a factory reset (which will wipe the whole device) to make sure it is not software related.

Interesting about the Nexus S, trying to track back if I unplugged or powered up the phone with USB in...
I just tried factory reset - still showing up that the battery is charging even though it isn't plugged in

Hi, I have the same problem since the 7th of December, first i thought an app or some sync was eating up the battery (i updated G+ and facebook the previous day) but then I noticed that it was not charging, now my GN is dead. I manage to turn in on when is on the charger a couple of times but now not even that. (I have used several chargers and usb cables with no luck)

Did you manage to solve the issue? I sent mine today to Samsung after trying to get a replacement from Phones 4 u.

Possibly chip in battery is bad? Havent confirmed but supposedly we have fuel gauge chips.

Iv had this problem twice now.....
it wouldnt charge past 12%, it would not show the charging symbol.... i shut off the phone (it seems to charge while the phone is off).. after 5 minutes, i turned it on and the phone was at 65%?
I tried to tell the guy at the verizon store and he would not do anything about it unless he could see the problem happen.... this doesnt always happen and its annoying as hell...
im thinking it is a software issue since it charges fine while the phone is off...

I was looking for a cause/solution as to why my battery life reporting seems so erratic, I will definitely take this advice and see if this might be why. So it should be ok if I only connect and pull the charger with the phone already on? What if I plug the charger in with the phone completely off and then pull it before booting, is that alright too?
It's funny all the new rituals you need to learn to get around the quirks of a new device (like having to turn the screen off and then back on again after docking my Nexus One if I wanted the touchscreen to work right haha).

I've been having strange issues with my Galaxy Nexus and charging for the past few weeks - I can't seem to get it to charge over 50-60%. Also, whilst it's 'charging', the 'Battery' details page reports 'Discharging' or 'Not charging', even though there is a charging icon in the status bar?
I left it to charge for around 9-10 hours last night, off the mains charger, and it only got to ~45%...
...as I mentioned, whilst it is charging, it never reports that it's charging. The lock screen also suggests to 'Connect your charger'...
...charging whilst the handset is off still results in a half charge. I've tried many different chargers/cables with no luck.
Strangely, I used to be able to only charge the handset off of USB, to 100%, but I've now lost that 'work around' :-(.
I guess I'll phone Samsung returns and see what they say. I'll post their response, in-case anyone else hits this issue.

Looks like they're sending me a jiffy bag to return it to them...

hmmmm, sounds broken

Mine is charging OK.
My biggest problem is that even when I have my charger unplugged, the icon is still showing that it's charging.
Look at the screenshots, the battery level is going down the whole time because I'm not charging it but it's showing a bar for charging at the bottom.
And if you look at the time on the clock, a few minutes go by and it still says 38 seconds on battery.

The gap in the stats is from a battery pull.

Did you ever find a solution for this problem? I'm experiencing the same problem and am unsure whether to try and return the phone or send it in to samsung.

Nope
Have to back my phone up in the next few days and send it back for repair/replacement.
It takes ten days, but if you haven't sent it back by then, I'll let you know what they say the problem was.

GN just died. Could static from pocket caused a short?

UPDATE:
Turns out my phone is not completely dead.
If I plug it into the computer, it registers a sound indicating a USB is connected,
but not more than 2 seconds later, it sounds again (the sounds of a USB error, Ba, dum, dum)
When I look at device manager, I see: Omap4440 quickly, but then it goes away. This recycles about 8 times and then it just stops.
I read that this might be due to the phone constantly rebooting.
The screen never turns on. I can't get into the bootloader since the screen is dead.
The only problem now is how can I go about this?
-----------------------
I had more than 90% battery because I just unplugged it. I did a reboot to clear any background apps (like restarting a computer, right?) and it just never came back on.
I placed it into my pocket for that minute while it was rebooting but I never watched as the screen went off. When I took it out of my pocket, it was a dead screen.
I already tried volume + power. And/also holding power itself for a while.
Plugging it back into the charger doesn't do a thing. No charge. Screen remains dead. No vibration is present to indicate the phone at least came on.
What is going on here?
My only conclusion is my jacket may have created a static field which caused a short when I pulled it out. Could this be possible? Especially since there are 3 contact points for the dock on the sides?
Using a GSM version if that matters.

try pulling the battery out for 3+minutes, then put it back in and try booting.

Sorry that happened to ya. I would plug it in and keep it plugged in for a solid hour, then try booting it up. I had that happen to me on a previous Android....HTC EVO. I was rooted and just died (even though it said it had plenty of battery). For some reason it lied and was actually out of juice bigtime.
Rooted custom ROMS have known bugs, albeit extremely minute bugs. Give it a try and report back.

Happens every now an then with most galaxy nexus users, battery pull always fixes it, no need to wait 3 minutes, out an straight back in works for me then hit power on button an you will get the vibe an boot.

yeah, i know what you mean because it has happened to me before plenty of times. But this, it's different. It's practically dead and all methods i've tried has not seem to work. I'm seriously out of ideas.

So it's been charging over night and the phone is still dead and wont turn on.
I've even replaced it with a spare battery which I know is at least 90% full.
Anyone? I'm so sad why my nexus just died like that.

rebump... =-( I am so that it just died with no reasons as to why... I've had zero problems with it!

You could attempt an OMAPFlash on it, then reload the factory image via fastboot.
That works for me about 90% of the time in GNex repair situations such as this.
Good luck.

Any water indicators showing water damage? If not, start contacting your provider / insurance / Samsung about a replacement.

Replacement man!

Simms is that you from the nexus s? If so, can't wait to see you uploading a quadrant shot of your next over clocked phone.
Op, plug it to a computer and check what happens. Otherwise call for a replacement.

Does this mean I will get a refurbish model? Can anyone quickly explain to me the process to get a new GN and the time it took for you to get your replacement?

If the power button itself is at fault, you can send a power on signal by plugging in the phone with no battery installed and then with the wire still plugged in insert the battery. This method requires no button input whatso ever
Edit , i used to do this by accident all the time while flashing htc devices. Not sure if samsungs hardware offers the same troubleshooting functionality and im not at a wire right now to test the theory. But its worth a shot.

I had something with these symptoms about 4 days into owning my phone.
The way I fixed it was booting into ODIN mode (vol down & power). The only way out of that one is also a battery pull.
Sorry: I meant to say: battery pull, ODIN, battery pull, then it turned on again normally.

I'll give this one a try. But I never thought a combination like that would revive a dead phone. I mean, it's dead as if it was just a children's toy with no electronic board inside. No power even though all 3 battery I tried have at least 90% charge. MY Charger is not defective as it works with my other phones.

Won't work since I can't even turn on the phone. Computer doesn't see it (Obviously because it can't power on).

Indicators show no water damage. This was in my pocket. Unless I pee'ed in my jacket, it shouldn't be wet there.
Thanks for the help guys, but I'm running out of ideas. There's only so much you can do with a phone that cannot turn on. =(

Basically, what you're seeing means the phone is still alive, but the firmware is corrupted.
Try this thread, and particularly this post.
No idea if it works or not.

Is this a hard brick or a soft brick?

This sounds like hardware failure to me. Drop the phone at all, ever? If not, could just be faulty hardware.
Honestly the Galaxy Nexus seems to be of poorer build quality (internals, screen, back cover, etc) than every other Android phone I've ever had. Not that I don't love my Nexus, just an observation.

[Q] P930 wont charge even after replacement port

I have an LG Nitro and for some reason it stopped charging. The notification icon shows it as charging but the battery continues to go down. I tried buying another battery as I thought maybe the battery was going out but this was not the issue. So next, I ordered a charging port and attached (soldered) it to the device, this also did not resolve the issue. I am kind of at a loss at what to do as the phone is in perfect condition but will not take a charge. The Nitro is rooted with TWRP recovery and CM 10.1 installed on the device.
I now have a Nexus 4 but was planning on giving the Nitro to my cousin but then this started happening right before my Nexus arrived.
Does anyone have any idea what is going on? All of the symptoms point to either a bad battery or charging port but this is obviously not the case.
Thanks

Also, if I plug the device in and hit the key, it shows the battery icon going up and down but it does not charge.

Come on, I know one of you has an idea as to what is happening

A few thoughts...
1. Are you using the official LG AC Adapter? If not, are you using an AC Adapter that's outputting AT LEAST 500mA? For me, in the car using GPS, even with a car adapter that outputs 1.0A, it can't keep up with charging the battery. It shows that it's charging, but the capacity continues to go down...
2. Are you using any kind of CPU under/over clocker? Like SetCPU? Check the settings and make sure you're not using some crazy profile, or better yet just uninstall it and test to see if things get better.
3. How about the USB Cable? Have you tried other cables to make sure you're not using a bad cable?
4. Double-check your solder work. Are you're connections clean, no globs or solder points covering more than a single pin? Connections are solid, nothing loose or gaps?
Good luck!

Thanks for your suggestions. I will look into your idea.

I do not think I have the charger that came with the p930 as it got stolen but I do have the charger from my Nexus 4. Do you think it will work? The N4 charger has 1200 milliamp output or should I order an OEM charger.

I think I used the charger from my HP Touchpad which is 2000mA but it didnt work. I may be mistaken.....
I will look into getting an OEM charger.

Might be charging...
Ok I made some progress finally!! I have a 700mA charger plugged in and now the LG logo comes on and then blinks off. :good:
Hopefully the battery is charging and by morning it will be working.
Wish me luck!!! :highfive:

I can get into download mode and would be able to get in to the twrp but I do not have a backup and my sdcard got corrupted.
What are my options now?
Thanks

The 1.2A from the Nexus4 is great. That should do nicely.
1. Are you ABSOLUTELY sure this adapter from the Nexus4 is working properly (have you verified that it's working fine with your Nexus4)? If so, then plug it into the Nitro.
2. If the Nitro is powered off, then when you first connect a power source, you should see the 'LG' logo come on for a second then go back off. After a minute you can short-press the power button and you 'should' see an animated battery icon that looks like it's filling up. The battery charging icon looks like this (lower quality image on the phone):

}
3. Let the phone charge for an hour. Now, press and hold the power button until you see the 'LG' logo, let go of the power button. The phone 'should' start powering on.
When you say 'Still blinking on and off', what is? If it's the soft-touch buttons on the bottom, that's an indicator that the battery is low...So, indeed the issue continues.

I mean the phone turns on, I see the LG logo and then it turns off. Then it turns back on and I see the LG logo and it turns off again. Make sense ?
I can get into Download mode just fine and would be able to get into TWRP but my sdcard crapped out.

I know about charging the device with the phone off (seeing the charging dialog) but the phone keeps turning off and back on blinking the LG logo.

If I still had TWRP on my sdcard, I could of went to the Factory Reset screen and went into TWRP and let it charge from there and then wipe it and install cm 10.1 again.
Is there anyway to load the recovery.img to the sdcard without being able to boot the phone? I am pretty sure I cannot use adb in Download mode so I am kind of stuck and I do not want to flash to stock if I can help it but I will if I have to.

I think its a hardware problem and your phone need to be repaired

The repairman told me he has exchanged some of transistors

I tend to agree with nss007, the constant fluctuation of the power/charging going on and off is a big red flag to hardware issues.

Well I actually took it to a cellphone repair company (only one in the area) and they had it for about a week and could not get it to charge. They also changed out the charging port and looked the board over. Of course, they were obviously not using the right charger as they could not even get the LG logo to come up. I am hoping that it is a software issue as the company could not find a single thing wrong with the phone or board. Of course, they mainly fix hardware (broken screens, charging ports, etc.) so I dunno how much experience they have with software.

A few months back, my Nitro fell off my table while the charger was attached. Ever since then, it is doing what you say; showing a charging icon but it actually isn't charging.
Just a few suggestions that I've learned over time dealing with this problem... When you are plugging it in, be sure it is setting where you intend for it to sit. Basically, don't plug it in THEN set it down. I've noticed that ANY movement whatsoever will knock the phone off charge but still show the charging animation/icon. This problem is completely independent of the state of the phone; i.e. what ROM I'm booted in to, whether or not I'm in recovery, and even with the device powered off.
How to tell if you are actually charging; open your settings and go to the battery settings. Where it normally says "Discharging" will change to "Charging (USB)" or "Charging (AC)" if you are actually charging. Even with the charger attached, any movement of the phone will almost instantly throw it into "Discharging" while still showing the animation/icon.
Hope any of this helps.

Invalid Battery Error With Genuine Battery

Hi All,
I have a LG G3 that I OTA updated to SEA 20c last week (second lollipop update). Since then, when I rebooted I have been getting "Invalid Battery" error with the genuine Battery that came with the phone. It was working fine until that OTA update. Since then I have factory reset the phone. Changed the battery to a brand new genuine LG battery. I don't have warranty on my phone because it wasn't bought in my country of residence.

Sometimes it will shutdown with this screen and other times it will just crash and try to reboot.
At random times while booting up their is this blue screen
Any help in this matter will be much appreciated. Is there a way to go back to an older version of lollipop?
P.s. Battery I am using:

so no developer has had this problem?
I am also currently having this same issue with a NEW, ORIGINAL lg battery.
Desperately looking for a solution but cant find anything at all....
Have you found a solution to it? if so, can you write down what you did in order to fix it?
thanks

Batteries are covered by warranty
Just take it into the place where you got it or your local LG Service Center and they should replace it for free

Nope no solution. I even bought a brand new battery and still having the same issue. Even downgraded still the same issue. What I was told is it is a Power/Battery Kernal Panic that is causing this issue. But not been able to find and solution. Mine is not covered under warranty and the service centre won't service it because it was bought from another country.

check if the battery pins are pushed down. I have the same problem recently and was able to solve it by aligning the battery pins

Have you tried re calibrating the battery by charging to full with the phone off?
taken from the web.....
What does it mean to calibrate a smartphone?
The Android operating system has a setting called Battery Stats which indicates the battery capacity, when it is full or empty. The problem is that it sometimes become corrupted and starts displaying data that isn’t real, which causes the phone to turn off before reaching the 0%. The process of calibrating the battery would correct the information.

First you must check the capacity of your battery, which you can see on the battery or by searching for its specifications on the internet. Check our hardware section for your device.
Install an application called Current Widget: Battery Monitor:
This application will show the battery charge in milliamps (mAh). Charge your smartphone for the duration of time needed until you reach the total milliampere amount indicated for your specific battery.
When the required amount is achieved, turn off the phone and restart it. The battery will now be charged to 100 % and in theory shouldn’t cause any more problems.
Method 2
Fully charge the battery with the phone on and when the phone is fully charged, unplug the charger and turn it off.
When your phone is off, plug it into the charger and let it charge to 100% again. The green LED light will indicate when this is done.
Next unplug the charger, turn on your phone and set the option to ensure that your screen doesn’t turn off, if you have this option. Then reconnect to the charger and wait for it to charge again to 100%.
Once loaded to 100%, unplug the charger again and do not load until the smartphone turns itself off after reaching a 0% battery level. Once off, fully charge it again and it should work properly. The screen setting can put back to normal again (meaning turn off after a certain amount of time).

Hi All,
I have a LG G3 that I OTA updated to SEA 20c last week (second lollipop update). Since then, when I rebooted I have been getting "Invalid Battery" error with the genuine Battery that came with the phone. It was working fine until that OTA update. Since then I have factory reset the phone. Changed the battery to a brand new genuine LG battery. I don't have warranty on my phone because it wasn't bought in my country of residence.
Sometimes it will shutdown with this screen and other times it will just crash and try to reboot.
At random times while booting up their is this blue screen
Any help in this matter will be much appreciated. Is there a way to go back to an older version of lollipop?
P.s. Battery I am using:

Im having the exact same issue, I even tried 3 different batteries and nothing!
Did you find a fix for this?

LG G3 ınvalid battery
I could not upload images
(Invalid battery), the device resistance burned

Could you solve the problem? I have the same problem with a replacement battery :/
It's maybe possible to disable the battery id check in the kernel?

Have you tried re calibrating the battery by charging to full with the phone off?
taken from the web.....
What does it mean to calibrate a smartphone?
The Android operating system has a setting called Battery Stats which indicates the battery capacity, when it is full or empty. The problem is that it sometimes become corrupted and starts displaying data that isn’t real, which causes the phone to turn off before reaching the 0%. The process of calibrating the battery would correct the information.

Please revive hard bricked Desire 820 dual sim please. (recognized as QDLoader 9008)

Hello.
I have Desire 820 dual sim. Three days ago, screen blacked out suddenly, phone poweered off. After that, the phone didn't power up.
I tried push a power button for 10 seconds or more, and volume up + power button, volume down + power button with similar way. Without charging or connect to computer with USB cable, no reaction has shown. When it is connected to power, orange led is blinking and does not power on.
When it is connected to computer, device is recognized as Qualcomm HS-USB QDLoader 9008(COM3). I found that is download mode for snapdragon SoC. I think flash memory is wiped out with unknown reason, and main board seems alive.
I searched the internet to revive this bricked phone, but I can't solve this problem. Even in xda developers.
Is there any solution I can do? I installed QPST package from Qualcomm which contains QFIL and etc. If I can install proper fastboot on this phone, it will revive. I bought this phone in Hong Kong, and I live in S.Korea now, there is no service center for HTC. Please help to revive my bricked 820. Thank you.

A similar situation just happen to me, the phone was ok, I got a voice chat and while hearing it the phone make a strange noise and went off. After a few seconds it came back up at the HTC logo, so I guessed it would boot back up and everything was going to be back to normal working conditions. To my surprise it didn’t happen that way. The phone was on a boot loop and I wasn’t able to go into fastboot, recovery or anything. Some minutes later the phone went off totally and it wasn’t turning back on. I plugged it to see if it was discharged and the orange led was just flashing, I leave it there for more than 30 min and the same thing was going on, flashing orange led, no power whatsoever.
What I did was to remove the device back cover, disconnect the battery cable from the main board for a few seconds and put it back. The phone first comes on normal and enter into android, but just of a sudden it start boot looping again. This time I was able to power it off and enter into bootloader to perform a factory reset. Once finished the phone seem to try entering into android but something happen during the boot process, phone goes back to the boot loop.
So what you can do is to try reseating the battery cable and see what happen. Be careful doing this since you could damage the phone or short the battery out which can be dangerous.
At least now when charging I have a solid orange light, I still have to work out the boot loop issue.
Let me know what happen.

How can I disassemble the phone?

Thank you for your thoughtful reply.
After read your reply, I decided to disassemble the phone. I searched the internet to do it, and I found a video disassembling it very easily. They peel the steaker(?) cover off located upon both speakers. How can I peel it off? My desire 820 is still in deep sleep.

you will need a small flat head plastic screwdriver or an lcd pry tool to just lift up the speakers plastic. beneath you will find two screws you must remove.

Failed to show boot screen after disconnecting the battery. orange LED still blinks.
I removed the battery line assembly and reconnected the battery.
But... orange LED still blinks. It's not different between before and after states.
When I connect the phone to my computer, it is recognized QHSUSB_BULK.

Never dropped the phone at all. Just after a call, it turned blanked. My PC isn't recognizing, can I do anything about that.

The problem can be accumulated, which mean it can caused by some environmental elements ( e.g. humidity, charging current and voltage ). These can lead to a sudden dead. Is your warranty still in effect? If yes, take it to your local retail shop and ask for repair!

My personal opinion here is that you may not want to pay for the repair fees as it cost you the same for a new phone...
