Up until this morning I had considered myself one of the lucky prime owners that had no problems with their device. The My prime has not suffered any of the defects I have seen other users having issues with, no screen bleed, great wifi, only a little issue with gps, and I purchased the unit from the one extra stock that the gamestop in SF received on the day they're delivered. Very happy overall with my firs tablet.... Until this morning..
Last night with my battery hovering around 15% I plugged into to charge, and got the wonderful little sound letting me know that night the morning I would have another full charge to waste f'in about.. When I woke up at 4 my prime was at 71% and status said not charging..... Strange I thought, and maybe a fuse had blown? No.... Every outlet in my house produces the same result.... No power getting to the prime
It was charged through a protected outlet in my server cabinet, so I know the power was clean and surge free.... Has anyone out there experienced anything like this before? I am thinking now that I will have RMA the unit because the charge circuits somehow failed.. I have no provision test another power supply for charging purposes and do nothing I have even seen extras available yet.. When I get to work I will verify that I still have connectivity to my pc and see what happens.
Please I would like some constructive thoughts on this matter.... I do not want to start another thread that catalyzes everyoneone into a fit of prime bashing or or telling me why I should returnitand buy a new device.... I am lookingfor hopefully a resolution or similar experience that can help me out before I make the decision to RMA for a new unit .... Damn and I only had a few days left to waitfor ICS
If it helps I am on the latest update 33, and rooted with jcase and viperboys (thanks guys, awesome work) tool....

Your charger is overheating. Did the same thing with mine, an hour in the freezer worked like a charm. Remember to put it in a bag though.
There is a temperature trip circuit in the charger, which evidently kills charging if the charger passes a temp threshold. This was apparently a very prevalent problem on the tf101, and has been known to carry over to the TF201 occasionally. I have not experienced it, but i have seen this 'fix' used successfully.
Definitely sounds worth a try then... I can try this fix when I get to work and report back... Is this something I should expect on a regular basis? I Can do it for a while until I can source a new charger, that I do not mind... At this point anything that keeps this thing in my hand and up and running is good news in my book. Thanks for the suggestion guys!

Please keep us posted. One of the first things I noticed when I got my Prime was how damn hot the charger got when charging. You can literally burn yourself if you squeeze it.
The charger is a piece of ****. Instable, overheating, buzzing, the one on my TF died a long time ago.
If it doesn't work anymore, find yourself a new one (that provide 12v output and not the regular 5v) with a USB port, it cost something like 10$ and you won't risk to set your house on fire each time you charge your TFP.

Well its not that strange.....I used to do this with clicking Hard Drives after they over heat. This would allow you at least an hour to access your files to recover them. Its a long known data recovery secret. ;-)

I noticed this as well... seemed a bit much for my like but as everything seemed to working ok I left it alone. I am at work now and chager has been in the feezer for approx 20 min... gonna leave it till the hour mark and I will update as to the progress of this very strange yet intresting adventure....
Alright... so my update on the problem.... Put the charger in the freezer for a good couple of hours to see if it could be reset... after letting come back to room temp, I plugged it in and nothing.... charger is blown. Had to go to office depot to get a new one, but the good news is that it was not the prime itself! Thanks for the ideas everyone!
Have anyone been able to charge their Prime from their PC like it says you can do in the manual.
I tried and the Prime didn't show any indication that it was being charged, in fact it still said to connect it to a charger.

you can but it has to be in sleeping or off even then it will charge so slow unless you have a usb 3.0 port like me

Op,
I have been watching people complain about this, if you plan to throw the charger away could I get you to toss it into an envelope and send it to me, I want to do some research on it to see if I can figure out why it is burning out.
Does anyone have a link to a cheap, compatible charger? I guess the voltage can vary as long as it's not too low, but the current should match that of the original charger, from what I understand.

Flyingwolf, being an engineer myself I was very curious about doing a little investigation of my own... But I only have a multimeter. I would hope this should be enough to get a general idea of what's going on. If you would like I would love collaborate with you on this and see if we can figure out what is going on. If I get to deep over my head (I am a mechanical engineer not electrical after all ) I would have no problem at all sending it along! Let me know and we can go from there. Was planning on cracking it open this weekend.

Far from being an engineer myself, however my love of all things electronic and my hobby of RC has forced me to learn as much as I can, I have become rather proficient lol.
Me personally I would just being doing some simple probe tests, figuring out if there was an issue with manufacturing (cold solder joint, too tight wire that pulls with heat expansion etc).
I am sure as a mechanical engineer you should have no problem figuring it out.

I paid 30 at office Depot for an OEM unit... I would recommend you always use the stock system to charge as it may have integrated circuitry to actually talk back and for to the prime for charging to correct levels. Further investigation as noted in my last post should hint at this so stay tuned. I will note that they keep the chargers in the back at my local store and when I called had no idea what I ws taking about. I had to give them the item number from online before they could find it... So I would check availability online and find a store that has them in stock before you go on a wander to find one. Hope that helps

Several days ago my phone started behaving strangely. Whenever the phone is NOT plugged in, the battery icon flashes continuously. If i plug it in, it stops flashing and behaves normally to show the phone is charging. Also, when the phone is NOT plugged in, the lock screen says it is charging. My battery life is dismal.
When i unplug the phone the battery indicator remains at 100% for a long time, but then drops quickly.Since this started i have to charge the phone twice a day with only moderate usage.
I am now on Shostock2 4.1.5 and Siyah 4.1.1. I tried factory reset, clearing cache and clearing dalvik. I also tried installing a different kernel (dream kernel) and a different ROM (aberration), wiping data, cache and dalvik each time.
I searched the forums, and the only threads i found seem to point to a bad usb port. One thread suggested cleaning the port, which i did using alcohol and compressed air. It helped for about half an hour, and then the problem returned.
Everything seems to point to a usb port that for some reason makes the phone think it is plugged in all the time...perhaps it is somehow shorted? So, it sounds as if my next step is to replace the usb port.
Still, I wanted to ask if anyone had any other possible solutions i could try before sending the phone for warranty repair and get the port replaced (or replace it myself).
Any ideas?
You are being kind of vague here. For instance. U say u have to charge it twice a day with .moderate usage. What if your moderate usage is 2.5 hours screen on time or something. To me, that means of course u will need to charge again if u want to make it he whole day. A bit moar info? Some cowbell?

Moderate usage means (for me anyway having the phone on, wifi on, gps off, no gaming. I only turn the screen on to check email for a couple of minutes here and there, and to answer the occasional call. Before the problem started my phone used to go all day without recharging. Now, even if i let the phone sit, unused, untouched, screen off (like overnight) battery level will drop over 10%per hour. I tried using better battery stats but none of the triggers have been triggered: if i try "since unplugged" or "since charged" or "since screen off" they all show zero seconds...I'm guessing that being "plugged in" continuously is messing with the triggers.
Still, the battery drain is not really the problem. The problem is that the phone seems to think it is plugged in continuously, even when it is not. It sounds like a bad usb port, or a port about to fail completely, but before i try to replace it i wanted to know if anyone had any other possible ideas.
People usually scrub the inside of the port with an alcohol swab if I'm not mistaken. Thought I've seen that posted, never had this problems myself.

My USB port needs to be replaced due to wear ( loose fit of cable). The ones for I777 I have found are $7.00 but are port alone, ones that are for I9100 are $15.00 but are attached to the ribbon cable. I plan to take phone apart to try to determine if the I9100 part will work. The price to have it repaired by MobileTechVideos is $40.00 plus shipping.

Definitely sounds like symptoms of a bad USB port to me. One thing you might do if you want additional confirmation, is to flash back to stock firmware (to rule out firmware issues...though I don't know of anyone who has confirmed this type of symptom being caused by bad firmware) and grab an older copy of BBS that will continue to report stats when plugged in (or maybe it will still do this if you set custom ref? I haven't tried.) There is a wakelock that will show for plugged in...vbus_present I think it is. Or you can also watch CPUSpy - if it continually thinks it's plugged in you'll get zero deep-sleep.
Thanks everyone for the suggestions.i tried sering a custom reference in bbs but no luck. No matter what i try they all show zero seconds. If i look at the battery graph in the system menu, it says the phone has been charging non-stop for the past two days, which is not the case. I will try cpuspy and report back.
Get a tooth pick and push up or down on the metal insert inside of port. May take a few tries but will work. I believe it is caused by your chargers 5 little metal cables bent when you plug into phone...

BBS update
FYI - I just grabbed the latest RC for BBS, and it now has a toggle-able option to log stats while charging (with a caveat to use at your own risk...stats may be inconsistent). Might be another tool for further investigation.

I tried cpu spy. i left the phone untouched, unplugged screen off for about 90 minutes. Cpu spy shows the phone spent almost all of that time at 200 mhz, never entered deep sleep. So it does seem to be a hardware problem, where the phone thinks it is plugged in continuously. i will carefully try the suggestion above to straighten the pins inside the port..maybe they are bent and somehow shorting. If i screw up the port....well, i probably have to change it anyway

Well it's not my cable. What it does is act like it is connected with no cable being connected. Therefor causing it to act like it is charging. Then it prevents deep sleep and wakes and vibrates every so often. Really quite annoying and killer to battery life...

So I have had this I9100 for about a year. Flashed with CM10.1 long ago and been reflashing new nightlies when i see stuff on the github log that address bugs I want fixed. Anyway the other night I put my phone charging, I didnt flash anything that night just a normal day. Next morning phone is dead. Wont charge, wont boot, no recovery no download mode, PC wont detect anything when I connect via USB. Odd thing is that now when the battery is inside the phone it starts heating up like crazy on both sides of the back camera/sim card slot, I guess where the CPU is.
So I searched for people with dead and bricked S2 and didn't find anyone with this problem, then I searched for people with other phones and again no one with this problem.
So I was wondering if USB jig would be able to help me, or JTAG, or if its just the usb board that died since it was while charging and it gives off no signal via USB to a computer and if I changed that it would come back to life.
What do you guys think? Was it the main board or is it just a fried USB board and the phone can't regulate power without it?
Sounds like the USB board, but you never know until someone 'qualified' has a look at it. We've had a lot of similar problems on here over the past two weeks (this week in particular I've seen maybe 5-6).
Doubt a jig or JTAG would be any good given it isn't a firmware type issue by the sound of it.
I guess I'll order a usb board a replace it. If it doesnt work its not expensive anyway. About $10.
I was wondering if there have been a lot of people lately with this problem could it have been one of the nightlies that screwed up power management and fried the board?

Yep if you can get a cheap one 2nd hand it's no great loss if it doesn't work & you end up needing to replace the MB as well. If you need them, I attached the SGS2 service manuals to a post of mine a day or two ago (click on my name & have a look through my posts over the past few days) if you need/want them.
That's an interesting theory. Not being a dev, I'm not up to spec on whether anything at, say, kernel level could cause something like that to happen (In the 18 months I've been here, I've never seen a kernel/firmware pinned down as the cause of something like this), but you wouldn't say it's impossible.

Did you try the ole toothbrush trick?? Get an old toothbrush and put it into the usb port an go mad. Sometimes a film can be on the terminals of the usb port, which gives you a bad connection.

With the multimeter check is there a voltage coming from the battery. The battery by itself!. Next leave the battery out from your phone and plug in your charger (which is connected to the wall). Put the multimeter across the appropriate terminals of the phone and measure the voltage if any.
Report any voltages values you have

The battery gives off a steady 4.
The phone connected to the wall without battery gives off 1.3 when first connected or the battery removed and then very slowly starts dropping to 0 going slower as it drops. By the appropriate terminals i imagine you mean the ones that connect to the battery wherethe battery has the + and - symbols.

That USB port is working, battery is fine. Next the screen might be dead. First check to see if the backlight is working. Turn on your phone as you would normally shine a light onto the screen and see if you can see anything. Use a flashlight or something with a high focused beam

So batery and usb charging normal. No screen problems, and heating cpu while off. Most likely main board fried? I'm gonna get some resistors to make a jig and try that anyway.

Yeah...that CPU heating is a worry.....it's obviously being forced to do something that it wasn't intended to do....and it doesn't like it.....
And with regards to changing the impedance of the jig....probably not advisable. ....micro electronics is very sensitive to resistance and voltage. ...what you're doing with the jig is essentially bridging two connectors. ...
Impedance too low....too much current/voltage passes.....things might begin to get hot (best case)
Impedance too high.....too little current/voltage passes.....no effect.....

So i've had some battery issues for quite a while now, on every single rom. These were mainly that the phone always seemed to think it was charging, but the battery "value" dropped. Battery also lasted half a day or so, even with Apolo regular. Lastly, from time to time, after resetting it, the phone would be at around 14% and start increasing every five minutes or so. So i just dealt with all that for a while, noticing that usb almost never worked and it would take the phone a bit to realize it was actually charging (it wasn't always "passively charging").
So the other day, i turned it off due to low battery, just saving some time later. Then i see the battery "loading" icon, then a green battery 3/4 full with the 5 dots in the bottom, it would get to the third one, then vibrate and turn off. I tried turning it on only to see the S II splash and having the phone turn off instantly. I also tried turning it on while charging, no luck. So finally, i tried google, and found this. I did it with a paper clip and a toothpick, it seems to be separated but there is a tiny bit of dust i believe. Well this did nothing for me and now i'm desperate to fix this battery problem that i have. And pretty sure i can't return the phone cause i violated the warranty.
PS: Running AllianceROM 4.1.3
My wife's S2 had pretty much these same symptoms. I replaced the USB board and everything went back to normal. I wrote a guide on how to do it.....

It's quick, easy to do and inexpensive to buy the part (compared to what a service centre would charge you).
Read the guide IN FULL if you want to DIY it........

Hmm...
Seems kind of a desperate means, isn't there a way i can do that without replacing it?
You got the best possible advice & a simple/cheap (guaranteed) fix from the person who is the expert on this sort of problem with this phone & you're questioning it ?
*shrugs*
Your phone stays like that then.
You *might* get a temporary fix by playing around with the contacts within the port.....but even if it works, it will ONLY BE TEMPORARY......
The Samsung service centres will certainly NOT faff around and desolder/resolder a new port to the board.....they'll just replace the entire board.
It's not like you are replacing the entire motherboard because on the S2 (unlike on some phones) the USB board and the motherboard are separate........

it happens when your charging port is having a short connection. perhaps u'd need to change the charging port. if your device is shorted or not, it can be tested. if you have a multi-meter, you can easily test it.

It wasn't meant as disrespect, just that ordering this kind of stuff down here in Chile is not easy or cheap, so if there was any other solution i'd prefer it.

That's the problem for me though... No Samsung services here in chile. Any way i can return it is with my service provider, which will probably see the triangle and blame this on that.

It's never as difficult as people think, all you need is access to the internet and a credit card or PayPal.
In my guide, I'm pretty sure one of the suppliers ships worldwide.....

Hey everyone,
I'm just gonna get straight to the point my charger has completely stopped working and I need a new bottom module. My phone model is the H850 is it really necessary to get the right one because I read up about people getting bottom module replacements and the phone says Insert a supported module and the phone will refuse to work. I'm from the UK could anyone link me a H850 Battery Module so I can buy the right one.
Many Thanks

A good idea is to find the charging cradle and spare batt. I got 2 g5s. So i ended up with 3 batts and a cradle.

God damn Scientist Hahaha you're well prepared! Yeah I got another spare battery with me obviously with the lg g5 battery's performance it is necessary to carry one with you. I'm not too sure about the LG battery cradle I just dont think its that useful to me I charge one battery when its full then i charge the other one.

I have several type c cords numbered the batts 1 2 and 3. So its never a out thing. I like the cradle as it protects the batt from pennies and such in the pocket. No one likes a rocket in the pocket. Lol:silly:
Im not big on the modular swap out as does wear and tear on the modules but my usb ports like new....

Hahah thats true swapping it does deteriorate the battery when swapping it on a constant use. My bottom module has come but It still not charging at all, I don't understand whats wrong with the phone I've checked for anything thats effecting the charging port especially the new one and found nothing. I had like 3% of battery left on my phone everything seems normal nothing is wrong with the phone except that its not charging at all.

Gonna be a pretty dumb question. BUT have you replaced your cable?? It might of had a sudden death or is your wire damaged by any chance, any exposed cables showing? If so then replace your charger wire not saying it will repair your problem but give it a try.
