[Q] Battery charge/connection issues - Captivate Q&A, Help & Troubleshooting

I'm thinking there is a hardware issue going on here, but any insight is appreciated.
I cannot boot from my battery. When I pull the battery and re-insert it screen shows it as empty, but... when I put in the battery with the USB connected to my computer, then it does show the battery as full. (and I am able to boot normally).
I've also noticed:
When booting this way (or out of recovery) I get a brief scrambled image before the i896 - Samsung logo appears
The battery charging and USB connected indicators will not change from what they are in when the phone is booted. So if i remove the usb after it has booted with them in, the battery indicator remains charing, and USB connected. (If I leave it for a long while, sometimes it does eventually detect it properly and switch over to disconnected).
Any thoughts would be really appreciated. I've talked to Rogers and they are sending a replacement, but I'd like to know what the problem is before I let Samsung start pulling it apart to look for water damage.
Thanks!

I found the solution to my issue:
(cannot link, search for usb connected notification stays after usb disconnected on android central.)
Turns out there was either surface corrosion or simply crud in my phone side USB port which was causing the connection mechanism to misfire or not fire at all. I guess when booting without USB, the phone thought it was connected so it just doesn't try to get power from the battery (who knows).
The linked thread had lots of responses, so I'm not sure why I didn't find it here or on android forums. I was able to fix the problem by cleaning out the port.
Hope this helps,

[Q] "USB Connected" always on

Captivate build 1008 here, running stock Froyo now (but the same problem occurred with stock JH7). Not rooted, but unlocked.
The problem: the "USB connected" notification comes up pretty randomly when the phone is NOT connected via USB. When this is the case and I power off, the phone refuses to power back on. If I pull the battery and put it back in, the "spinning sun" icon (???) comes up, followed by the battery charging icon, exactly as if I had connected the phone to the charger---and the battery is shown to be completely empty, even when it's not.
Usually, after doing this a few times, the phone comes back up.
This is driving me insane. The fact that the problem is random makes me think of a hardware issue, but any wisdom would be greatly welcome. I'd hate to have to send my phone in for service or replacement :-(
Thanks in advance! M

I had the same issue yesterday. Here's what I did: turned off the phone, pulled the battery, pulled the sim card, pulled the microSD card, waited one minute, then put everything back in. USB icon is all gone!
My phone did that after I upgraded to froyo. I turned off USB debugging and powered off my phone and I have not had the issue anymore.

I'm seeing the same/similar issue when I charge my phone and remove. I can get it to toggle off by inserting the USB and messing around with the various connection prompts ("Kies" or "Mass Storage"). Don't recall exactly.
@aicirt17 OK, I'll try removing the SIM card, too (I haven't done that). I don't have an external MicroSD car. Thanks.
@mmarquis I also fiddle with those settings. It's the randomness of it all that kills me :-(

USB port issues

I appear to be having wired issues related to the USB port as has been previously reported on the Galaxy S2.
When not plugged in to anything, it constantly says it is charging. It will not let me select between USB debugging mode as it says the cable is connected.
Despite it's belief that it is charging, when I actually plug it in to the mains to charge, it doesnt charge!!
If I power off the device, it shuts down correctly, however it will constantly switch between the grey battery icon, then a almost full green one, then off. It then wont allow me to turn on the device. Ive tried plugging it in to the mains (but I guess that as it wont charge this way, this is why it wont let me turn it on this way either) the only way I can boot it up is holding vol up, middle button and power together for 10 seconds or so. It then goes to CWM recover where I can reboot the device
If I plug in a jig, that allows me to connect a USB flash drive, it all seems to work OK. it no longer says it's charging, and i'm able to mount the drive.
The only way I can actually make it charge, is by plugging in to a PC.
Im very careful with my USB connectors, and I can only think that slight dampness may have entered as the phone has been with me in the bathroom during showers.
I dont want to send my phone in for repair, my first plan is to wait it out and hopefully any moisture dries out. Ive tried cleaning the inside of the USB port, but it makes no difference.
If I changed the USB port myself, a) is that a hard task, b) would it solve my issue?
I had a very similar problem with my note.
Solution was to take out the battery and leave the cover off, in a dry p;ace over night. It could definitely be related to dampness in your phone.

[Q] Galaxy i9000 won't boot - waits for a charger every time

My Galaxy i9000 - currently on DarkyRom 10.2.2 (Gingerbread 2.3.4) - has developed a nasty problem: It doesn't boot without a charger attached.
The main problem seems to be that the Galaxy seems to detect a connected charger all the time - even if there isn't one. Battery stats reveal that - if the Galaxy is up and running - a connected chargers is indicated for all times, even if it isn't through prolonged periods, e.g. during the day in normal use. At the same time a different page of the phones's status info indicates that the battery is being used - confusing ...
I've cleaned the USB port thoroughly, tried different batteries, different ROMs (installed stock 2.3.6. for instance) - even dismantled the phone to see if any dust or signs of corrosion were detectable at or near the USB port. There weren't any. At least I didn't see them.
Now I don't mind that the Galaxy thinks that it is charging all the time if it runs properly anyway. Even if it means that there is a 30 second delay until a plugged in charger is recognized (the charging beep is heard and the charging animation in the status bar starts only then). Also I don't mind that the phone needs even more time - around a minute - to detect a disconnected charger; this is the time it takes until the charging animation stops in the status bar after pulling the plug. BTW: This doesn't change anything in the battery stats - they shows continuing charging all the time, regardless of a charger being plugged in or not.
I could live with all that - but the thing that really hurts is the Galaxy not booting at all without a charger (and a wall socket) at hand. Without a charger the Galaxy boots only to a charging animation - in this order: 1. rotating hourglass icon, 2. empty battery symbol, 3. black screen. These three screens repeat themselves in a loop. If you plug in a charger you get a filled battery symbol after 1 and 2 - and at this time you even can pull the plug, and in spite of that the Galaxy will boot instantly and without problems.
So it seems that the phone senses a connected charger, waits for the current, doesn't detect it and goes at it again and again. Once it detects it it's ready for anything further.
Now my question is: Any ideas on what to do? Which USB port lines could be having a short circuit causing this behavior? Is there maybe a software solution for telling the phone that a charger isn't connected? I got root access and Root Explorer is available.
Thanks for any help on this!
Phil
... hope I wasn't too confusing with my original post?
To keep it simpler: My Galaxy S i9000 doesn't boot without a charger attached. Reason is that it detects a connected charger all the time - even if it isn't actually charging. My question is: Is there any solution to this via software? Any possibility to change the "connected charger" status?
Or is this a problem that cannot solved via software? Where do I have to look at the hardware then - any locations where to spot and rectify a short circuit maybe?
Thanks for any help on this!
BTW: Attached find a screenshot of the battery stats running for several hours and days - it clearly shows that the uncharged battery slowly depleting, while the "charger connected" status is on the whole time.

you may need to change the USB connector , its shorting inside vbat to vbus, best to send it samsung, if still under warranty or try checking your micro USB port and cleaning it first

Thanks, it's out of warranty, but I'll try to clean it again more thoroughly.
Your explanation that it's shortening vbat to vbus is greatly appreciated!

[Q] i9000 battery problem, charging port or hardware problem?

Hello. Recently i bought SGS and didnt know of problem it has. It ran stock eclair. Once i plugged charger it started to chage but when i unplugged it showed i charge it anyway. I reset default settings but then phone showed that usb is plugged in although it wasnt. But the most annoying thing that i cannot turn it on if charger or usb not plugged in. After it shows start screen with samsung galaxy logo i can unplug it. If i do not plug charger in, then it start showing circle then grey battery and then restarts that same. I upgraded to gingerbread stock but booting problem still hapens each time. My husband tried to look inside the phone, in the charging port there were signs of liquid but all other parts of motherboard were clean. Dont know what to do. Phone works fine when i use it, no other complains.

try cleaning the USB port as mentioned here and also the image at the bottom, for a guide on how to identify where the problem may be to resolve it.
Check this out! Links to useful Guides and " Banned " Documentaries ​
My husband cleaned the usb port, and i updated software. It is charging normally and usb recognizes it, but with a little delay, and also chen i unplug charger, phone detects it but with delay. But not turning on still present. it looks like in other posts battery bootloop. show little circle, then grey battery wih same circle and again. it tries to start even if i turn phone off. I turn it off, after 10 secs it starts to show that circle and grey battery.

I think those are hardware related problems. The problem when turned off could be that the phone knows that its getting charged not only through the voltage of the charger but also through a shortened (to mass?) pin. Maybe this pin is always shorted because of the liquid etc. you could try to clean it again or buy and change the usb port
Probably the phone have a history o drowning/soaking from water or some kind of liquid. If you could dismantle all the parts, but be sure you can assemble them again (try to search Youtube, I think there's a lot of guides on how to do it). Clean all parts with anti-static compress air in can, I think you can buy them from electronic shops. Give special cleaning on the USB port and buttons contacts. You can also blow-dry it with hair dryer.
Hope this helps solve your problem...

[Q] Droid 4 not powering on or charging after battery replacement

A coworker decided to replace the non-user-replaceable battery in his Droid 4 (it's actually pretty simple to do). The surgery seemed to go fine, but immediately afterwards the phone is basically acting as if it doesn't have a battery in it:
'M' logo comes up when plugged in
Holding VOL UP/DN+PWR allows access to the boot menu, but none of those options allow it to boot past the 'M' logo
No response from power button when not plugged in
Immediately powers off when power cable disconnected
I read that a factory data cable might help him, so we ordered one of those. This cable allows the phone to boot now (furthering the suspicion that it doesn't think there's a battery in it - the factory cable is supposed to allow this, and there's just an exclamation point for the battery status), but isn't much help otherwise as data can't be transferred from it. Point being, it's not a software brick - it boots fine with the factory cable.
Could this just be a bad battery or something? Has anybody here ever seen this behavior?
Thanks!

Hi,
It might be a loose connection. Did you make sure that the screws were fastened properly? Also check the battery contacts on the phone and the battery, clean it if necessary.
Are you sure that you didn't bend the battery ribbon cable? It is pretty sensitive, can be damaged by bending.
I'm pretty sure that the phone is OK, it's a battery connection problem.

This is screaming bad battery to me - either it was duff in the first place, or has been damaged during installation. Having said that, I've swapped lots of batteries multiple times, and have never damaged one during removal or installation, so if they were careful I suspect it was bad in the first place.

Thanks for your input guys.
He's ordered a new battery and I'll be the one installing it this time. Will update when we get it in.
