Hi everyone! Sorry for my poor english but I need help. I know that maybe there is solution inside the forum but I can't find it (blind!). So...few weeks ago I noticed that tablet's energy suddenly went down from about 30% -> 0% (and it happened after each charching) . Before this situation I was able to work on 1% (with dimming of course) for quite long time... So a week ago after connecting charger I saw on the screen a charching logo but there was now effect (You know - the green battery). I connected tablet to AC charger and to USB port on my PC there was no effect. When I tried to switch on - tablet starts and after booting showed 0% of charge and ****ched of. So... I took back cover and disconnected battery for few houres...and without USB charging tablet starts and showed 6% of battery then went o 5% (dimming) and it happends again and again. So my question is: Anybody knows if changing the old battery for a new one (replacement) about 30$ will solve this situation? Thank you in advance for your replies
Battery and charging port will fix this. Only mention charching port because its cheap and easy to replace while swapping batteries
Ok! So now I have to look also for a charging port . I'll do it. Thank you for advice!
I had the same issue. I sent the tablet to a service center. They said the charging port was gone, and the battery is weak too (after 3 years of heavy use). Both replaced for $69 (including tax). The battery is OEM, much better than cheap Chinese ones on eBay.

red light means extremely low batt.....guess your battery is faulty
i got the same thing.
and no it's not the battery.
it's the charging circuit on the main hardware isn't working.
open your phone and check the five small wires that they connect the mini usb to the main mother board, one of them must be cut.

so, is there a solution to this? or there really is nothing more for the device but the trash bin or for spare parts?
Have you tried this?

If you already replaced the battery and nothing, and you want to get rid of dear Uni place it for sell in parts on marketplace, a lot of people will go for it!

I had exactly the same thing with my old battery,after my try to discharge it with a lil electro-motor. then i found a post of a guy with the same thing,who fixed it-by "zapping" the UNI battery with a 9V battery,connecting + to + and - to -,for a few second. I tried it without thinking twice. It worked for me. Dunno how and why,but it did. I use the battery again,normal. But beware,it is dangerous to play with this type of battery,it can explode. Do a search on this subject and you will see
I agree with keeping_sg
how long have you left your uni on the charger?
just plug it in and leave it on the charger all night and see what happens.
I bought yesterday a 4800mAh battery from Hong Kong... 10 euros included shipping + FREE black back cover
Good battery life but still prefer to carry 2 original sized batts rather than get that big one, making even bigger our Uni
Respectfully,
Yes, that absolutely means your battery is dead. Try charging for a few more hours and then turn on your PocketPC. If the error persists, try changing the battery.

Hello,
I bought a GN, I9250, European model, made in China 4 days back from a vendor online.
I am having problems charging the phone.
When PHONE is ON
1. When plugged into the included charger/cable, the battery status shows CHARGING (AC) for a few minutes and then changed to NOT CHARGING. Removing the USB plug or switching off the mains and restarting in a minute takes the status back to CHARGING (AC) but again for a few minutes.
2. Tried with multiple chargers and cables with exactly the same results
3. When the phone is connected to USB port in laptop, the charging happens, for a longer duration. The laptop also detects the phone immediately and I can access files etc. After say 20-30 minutes odd the status again goes to NOT CHARGING. However, while the phone is not charging, I can still access files on the phone. This implies the USB connectivity is still perfect, only the charging has stopped.
4. Under no circumstances does the charge go beyond 50% odd, irrespective of the duration of charging
When PHONE is OFF
1. The phone shows the battery icon with bolt for a few seconds and then shuts off. If I click the power button briefly I can see the battery charging icon.
2. I kept the phone in charging with the wall adapter all night, and got 49% charge only, starting from about 10% when put to charge.
The battery indicator graph shows the phone is has never hit a charge level above 65% types.
I have not seen the other charging issue of the phone showing a bolt in the battery icon even if the phone is not plugged in ! (thank god!!!)
I bought it "as new" condition, and performed a factory reset immediately on receiving the phone. So its running stock applications, with almost everything except voice and 2g data on. No applications except Whatsapp are running.
All other aspects of functionality are working well.
I have read hundreds of posts across the web and am not sure what the problem could be with my phone. I am in India and since the phone was bought off the net, its unlikely that it will be provided warranty etc here. In fact I'm not even sure if there will be servicing competency in the technicians here.
I have tried to puch the micro USB tongue by pushing it upwards gently, but cannot really say whether or not it did bend or i was just too fearful. Have tried removing battery etc and all other soft methods written everywhere.
Any help ???
maybe a screwed battery ?

Hello,
I do suspect it myself, but I don't know how to verify this. Can any other Samsung phone battery be put in the phone or is the phone compatible only with this one? Getting another battery is not possible in the near future since this is not available in India...
Any thoughts on how to check this?

I have the same problem, but it's not the battery's fault. My brother also has a GNex, and I tried charging my phone with his battery, and vice-versa, without any luck. I think it's the USB port's fault. Something about power not getting to the phone correctly. Luckily I bought it at a store here. I talked to the owner, and I'm going to exchange it for a new one tomorrow.

Hello,
I found another GN and did this experiment.
1. When I plugged in my battery which was showing 53% on my phone into the other phone it showed 79%.
2. When I charged the other GN with my battery inside, it charged to 100%
3. When I put my battery back into my phone, it showed 67%
4. When I put in the other GN battery into my phone it showed 49%, while it was showing 82% in the other GN.
5. I was able to charge this other battery in my phone to 60%.
6. When I put it back into the other GN it showed 94% charge.
Apparently my battery seems to be ok. Also, it seems that my phone is charging ok too. But there may be a problem with the phone detecting the battery level !!
Any thoughts?
Hello,
i have exact the same problem. I tried 3 batteries a lot of chargers and i changed the Charging Port Flex Cable.
This all without success

Hey guys I'm a newbie here so please excuse me for my mistakes (if any).
My 13 month old Galaxy Nexus i9250 started giving me problems last week when it randomly started doing 'phantom charging'. It was gone for 2-3 days then it came back again. I removed the battery cleaned up the Micro-USB port a bit and then it became normal for another 2-3 days.
A couple of days ago when I connected my phone to my laptop, Windows 8 gave an error "USB device not recognised". I tried different USB cables but without success. Yesterday the phone stopped charging from the official Samsung charger. Somehow I charged it using USB charging by connecting to my laptop. Today even the laptop charging stopped . I've tried powering off, removing the battery/sim and plugging back in countless times but to no effect.
Weird thing is, when I Power off the phone and then charge (via charger or USB) then the battery charging icon on the phone appears. The charging bars fill the large battery icon 2-3 times and then the icon vanishes. Again the battery charging icon is displayed with the same battery icon getting filled again 2-3 times. This cycle continues and even after an hour or so but the phone doesn't charge a bit.
My guess is the micro-usb port of the phone is faulty. I'll be going to get it repaired tomorrow, most likely. Sad thing is, Samsung service centers won't provide any support for the Galaxy Nexus here (I'm in India) so I;'ll probably have to shell out a lot of money.
Anyone with a probably cause/solution? Anyone with similar problem?

Try bending middle pin of mini usb port with a needle.
use search button, there are too many threads about fixing usb port
Hi,
yesterday I bought a used R800i, the seller said I just need to charge the Battery. So back at home i plugged it to a charger an the LED near the power button startet blinking. First I thought it´s not a big deal but after a couple of hours it was clear that this is not alrigt. Even if i remove the battery the red light keeps blinking continuous (not 3 times or something similar, just every second once). I don´t know if it´s a software or hardware bug but could you help me to get it fixed?
best Regards
Lukas
It could be empty battery (but voltage level is not high enough to start charging).
Check with flashtool can you enter flash mode or fastboot mode (if you can, then it's probably empty battery)
If you can, check voltage level of battery with voltmeter.
It can be that motherboard is dead, but to be sure, you must know what is voltage level of battery.
For now, try leaving it charging, it might take some time (few hours or more) to actually start charging...
Sent from my R800i using XDA Free mobile app
Over USB i only get unkown device, but USB with the Test Point works, measuring the Batter was 0 Volts but charging over hours didn´t help

If battery have 0 volts then it's dead and (most likely) can't be charged anymore. You need new battery, so you can know is motherboard is working or not.
But that is just my opinion, and i could be wrong...
Maybe to try and charge battery from external source of 5V power , easiest way is cut some usb cable or take two wires from PC's molex connector (red is +5V, black is GND) and charge it for shortly (about 30sec-1min) and measure does it have at least 3.2V. Repeat short charging untill it does. If it stay on 0V then is dead for sure.
I was really able to charge the battery over a cut USB cable. I got it to boot until lookscreen (digitizer does not response) but then the battery turned hot and the Xperia shut down. I ordered now a new battery then it should work again

Digitizer not working could be faulty slider-flex cable or simply software error due overheating. You'll know with new battery...
Flex Cable looks like this, should I get a new one?

Yes, that's slider flex cable.
But wait untill you get new battery. Then you'll know does it have more problems or it is working normally
Sad News, today I got the new battery and i was even able to boot up the phone, but like the last time i was able to boot it up the battery and the mainboard got hot. I think the loading circuit is broken. So there are two options 1. buy a external charger for the batterie or 2. sell the phone as rarely used on ebay
No really I´m selling it, even if i get a charger theres also the problem with the not working digitzer. Thanks for your Help but this is ways to big for me.
Regards Lukas

Sorry to hear that. Obviously problem is much bigger and hard to tell what is wrong without some proffesional look into it (lot of reasons for phone to get hot by itself - there is short circuit somewhere and that's why it's draing battery fast and causing overheating). I don't think external charger will solve problems.
Anyway, good luck :good:
The title is a little barebones so I'll try to explain. I recently had to get a battery replacement due to the original one exploding, and all was great, until it hit 0%. It stopped charging. I thought maybe it was the battery again so I replaced it once more. The phone charges while it is on, but once it hits 0% and turns off, the battery refuses to charge at all. I thought maybe it could be the charging port, but wireless chargers don't charge it either.
I did a dumb too and didn't send it back to LG to get it fixed in the first place, so it's officially out of warranty and will cost $900+ to fix. So far nothing on the internet has helped at all, so I'm thinking this may be a unique issue and I have no idea how to fix it. Any ideas?
Thanks in advance!
Try booting into download mode without battery.. Then try to connect it while phone is on.

Hi I've got this very issue, was it ever solved?
No help but disharging your battery to 0% is realy bad for your battery. Try to charge it as offen as u can. It will extend your battery lifetime
What chargers did you try to charge the phone with?
I've had multiple "bricked" devices live again after connecting them to a charger that supported Qualcomm Quickcharge (or at least supply more than the average laptop USB port).
