Hello forum! Recently my phone died due to unknown circumstances. I thought it might have been water damage so I disassembled the phone and swabbed the PCB with isopropol alcohol and left the phone in dry rice next to a heater for 24 hours. This didn't fix anything so I took it back to the store of purchase and asked to test a new battery. Success, the phone turned on with a new battery in, however, when it was put on charge, the phone became abnormally hot. I thought this may be due the new battery, but it wasn't. After a small period on charge the phone paused charging because the battery temperature was to hot, I removed it from the charger it had only accumulated 30% charge and 20 minutes later the battery level had dropped to 2%.
Someone has suggested I was sold an aftermarket battery, however at the time the person from the store claimed they had to get a battery from a new S2 box.
So, I'm a bit lost as what to do next, could flash stock firmware and take it to a samsung service center, but I'm more interested in a possible DIY fix and the knowledge that comes with it.

Okay, yeah a return would probably be the best way to go about it. When I opened up the phone and had a look inside, the moisture indicators looked like a small white square with purple crosses on it. I would post a link, but new users with less than 10 posts cant post links.
But otherwise I think I'll follow your advice, and return to stock/un-root, I don't want to risk toasting the phone even further.
Thanks.

Have encountered more issues. Was in the process backing up phone. Turned off phone so I could reboot it into recovery and do a full wipe. But it refused to turn on, and doesn't show any signs of charging again.
So can't really return it to samsung or its place of purchase because it's still rooted.
What are the chances it the power IC that is malfunctioning?
I'm considering buying a charging/usb port from parts4repair, I've heard that the xda community has had good experiences with that website.
Any advice for a person in my situation? Bite the bullet and buy a second hand SII?

First, sorry for having to repost this as its own thread, I tried within the jokersax ROM thread, but I think that my question got lost in transition. Anyway here is my issue:
Am on Joker;s ICS 6.0 and I have been using his rom since 2.0 and from 3.1 have just been cleaning cache and dalvik. then installing whichever was the new ROM. But since 5.0 am having a very crappy battery life and if I let the phone die (0%), the battery doesn't charge back. I tried to use a USB connected to a PC (3 hrs on charge), plugged into a power socket (Overnight) and I even tried two other chargers and all those did not work. I could tell that the power was getting to the phone as I had a steady white LED on all the time.
To go around this I had to remove the battery and charge it with an external battery charger, then once I put it back (30%) I was able to continue charging it using a USB cable connected to the computer.
Now I can charge the phone if I plug it into a USB port on the computer, but when I plug it into a power plug directly, the phone shows the charging indicator, but instead of charging it discharge.
Any help?? ...Please !!
I just found that they are other MoPho users on Motorola official forum who have/had the same problem: Mohp won't charge on AC/DC, but unfortunately no solution found so far
<MOD EDIT> Thread moved. Belongs in Q&A
Either a bad charger or you got corrosion in the charging port and/or spilled into the circuit board. Here's a question for you: do you find you have to jiggle or hold the usb charge cable in the port a certain way or apply pressure to get a xharge? Likely a bad charging port. You may not think you have corrosion but it's more common than people think who swear they never had water damage to their phone; in my case, progressively leaving my phone in the shower room on and off for a year and a half degraded my charging port causing increasingly inefficent charge until I had same prob you did. Could be electrical too (maybe overclocking?). Before you rule the software as a culprit my advice is go tour manufacturer's phone store and FIRST buy a new high quality charger. Ask to test in store first. If it works, you should be ok and if it fails most phone company in store purchases on accessories come with a 1 year free replacement warranty. If the new charger is not working you can get a free diagnostic test to see for hardware or software issues which may entitle you to a free replacement or if it is "your fault" which most in store testers may say so they can sell you a new phone or get credit from the insurance company they work with (it might be), then if your sevice is insured, go through the insirance process and get a new ir remanufactured phone for a small fee. These usually have a 1 yr warranty and you can keep your stock sd card and charger and shipping is free. Warranty is usually for a year but unlike unforeseen issues like corrosion (shower steam will do it over time if phone is unexposed) then warranty is void from insurance co. It could also simply be a bad battery and you can always in store try before you buy a new battery (can't be oem). Even if it is a bad port ir corrosion damage, a "new charger" might work like a charm. Just be sure to tell store you used its products and don't be rooted when you bring it in. The store should be able to transfer most if your sata once your "new" replacement phone arrives. Make sure before you go through insurance you exausted all other options because as soon as you send in the affidavidt even if you later find a solution or fix to your phone's charging issues, you still have to send it back or be charged the full price of the usually refurbished phone. You could also always try a nandroid backup, save to an external soure, format/wipe phone, then restore and see if that helps (assuming you're rooted).

I ended up sending the phone in to motorola and they gave me a replacement unit. Thanks for your help
Ok, Here's what happened
I was cleaning the toilet at home and foolishly placed my phone on the tank, as I finished I picked up my phone, slipped out of my hand and fell in the toilet. I know I know, why did I take my phone to the toilet? I have no idea, its the first and last time have done that.
Anyway, I removed the battery, sim and sdcard straight away and tried to dry the phone off as much as possible, then placed the phone and battery separately in a concealed bag filled with dry rice (to absorb moisture), I can now boot my phone.
The problem is that the phone says I need to charge my battery, now when I try and connect the charger, it says, 'Charging has stopped due to overheating'.
My question to all you pros, is this a battery or phone issue? I don't really want to order a new battery to find it's a problem with my phone. If it helps, when I tried charging it, I noticed excessive heat down one side of the phone, as shown in the attached image.
Be gentle :crying:

You didn't mention how LONG you kept the phone components in bags of rice before trying to reassemble and power the phone.
If it was anything less than several days (if using rice as a desiccant, most recommendations I have seen are a week, minimum) and this is the only technique you attempted to use to dry the phone out, then it is very likely the phone was not completely dry when you powered it back up, and you may have permanently damaged key electronic components by allowing an electrical charge to flow through them before they were completely dry.
MistahBungle's call of the board responsible for the USB port is a good guess on which component, though.
Thanks for your replies guys.
I only kept it in the bag for 48 hrs. As you mentioned this probably wasn't long enough. I may just try and claim through our house insurance as it does cover smart phones, I don't have normal phone insurance because I've never needed it until now.
Thanks again for your help.
Hey guys! I'm needing some advice/tips.
I've had my g tablet for about a year and lately it really has started acting up. The power reading on the tablet was either like 100% or dying. Last week it just crashed when loading even though I had charged it. I figured the battery was bad and bought a replacement on Ebay, The power socket had been loose for awhile and the whole thing actually fell out of the tablet when I took it apart. I had the socket soldered by a local guy at radio shack since I have no experience soldering. I replaced the battery with no problem and now the tablet will not charge. I can not tell if the new battery I bought is defective or just need a full charge since it seems my tablet won't charge with either battery installed. The connections from the power socket to the motherboard look good, but I'm wondering if the repair man could have messed up the soldering. When I put the original battery in, the tablet will boot up for a bit and then die, but I get nothing from the new battery. I left the new battery in and plugged in the charger thinking maybe the indicator light had gone bad, but that didn't make a difference. I just wondered if anyone had some suggestions for me. (I've been taking apart and repairing my own electronics for years now, so I am confident no damage occurred while I have been tinkering). Any ideas are much appreciated! Thanks!
See this thread. If you can boot into the ROM or ClockworkMod, then you can use the awk script I've written to find out what your battery is doing--charging, discharging, full, RSOC, etc.
i've been using my phone since last year and last month it died.
i put it on the table, went to bed, then in the morning it was dead.
i've tried to boot it(didn't boot,no download no recovery), charge it(wall charger,usb charger no charging), different button combos(soft reset?),different batteries; tried to clean the usb port etc.it didn't responed to anything.completely dead.
it was running a cm nightly(june maybe), no oc or uv or anything out of casual.no eMMC bug, no software change(inc. apps).
after i left it in charging couple hours, i sent it to samsung.after a week they said "motherboard issue,liquid damaged;so no warranty".
funny thing is,there wasn't any water near the phone that night.
i asked "did you replace anything in the phone" they said no and i left.
then i got home,plugged the phone, nothing.no sign of life.
and without anything to lose i hit the power button and,and IT'S ALIVE,IT'S ALIVE IT'S ALIVE!!!!
it was a emotional indeed.it brought back to life.
everything was there as i left(messages, call log, candy crush everything, also recovery and download).
a lot of questions popped in my head.but i thought samsung fixed it but forgot to bill me.
after i used it for couple hours battery got low.so i plugged it left it for couple hours then checked it back and it didn't charged.i plugged it to my laptop and nothing changed,just nothing happend.
i called the samsung, asked about my phone they said that they didn't do anything(didn't replaced any part or software).
phone can boot but cannot charge(and no usb recognition).everything else works normal.
every once on a while i call my phone back from death with a fully charged battery for a little fun,i use it like 12 hours then the phone dies again.
i don't know what happend in that service center maybe they did some sick satanic ritual,or voodoo on my phone.
maybe it'll kill me i don't know...
did any of you heard anything like this.
(
note:this is a sudden death case but it's different than others.the phone booted but couldn't charged.i don't think it's a software issue could be hardware but can't say for sure.my warranty is ended so i can't take it to samsung for free.
motherboard costs a lot of money and i wont buy it.
now some say it could be damaged because of humidity or sweat or rain or tears ...
but i want more from that, i want a solution from you people.
it's a cliche but "sory fo my englis"

Check on eBay for usb connector board, it's about ten bucks and easy to replace, you got nothing to loose..
Good luck!

thx for the suggestion.I already ordered one two days ago.I just hope i won't need any sorcery.
btw do you have any idea about how can this happen.
Phones don't have to be exposed to ' obvious water' (drop it in the toilet, spill a drink over it, etc) to be moisture damaged. People either don't notice or forget the time 12 mths ago they checked their text messages & a bit of rain got on the screen, or the time they had it in their pocket in the bathroom half an hour after they had a shower. It doesn't take much, and it almost always takes a long time for problems to manifest.
As Karpfenhai said, if you're lucky it's just the USB board/port, but don't be surprised if the problems reoccur intermittently again after a while; in that case, you're probably better off getting another phone than going down the motherboard replacement route.
Hi folks,
First things first: I know there are a lot of threads concerning the "red light of death" for Huawei and other devices. I already read so many of them that my head is spinning xD However, I have some questions left and I need to distract myself from getting crazy due to the possible loss of data on my phone (and I have to wait at least until Tuesday for any news regarding the phone...)
What happend?
- Phone restarted while surfing
- Went into a bootloop
- Tried a soft reset
- Tried eRecovery --> Not succesfull
At this point I had to leave the train and the phone had turned off anyway. Wanted to charge the phone at the airport and back up recent data. Removed the protective cover and noticed that the battery was bloated. Since I was afraid I unplugged the phone and came to the conclusion that the phone doesn't work due to the defective battery. Back at home I ordered a new battery - didn't help. Phone won't turn on, softboot doesn't work. I only see a solid red LED when I try to charge it. Bought another battery - nothing. Went to a repair shop: This is the point where I start to have questions
They are all very nice at this place and maybe everything will turn out fine but I just can't wrap my head around certain things.
At first they also wanted to check for a defective battery and possible repairing errors since I replaced it myself. Today they called and let me know that the new battery is alright and they now want to order a new screen module. Later today I went to their shop to ask how much everything will cost and also to ask them about the procedure. I asked them why they want to change the display. Answer: Since the battery is fine, we believe the screen cable got damaged when taking out the old battery - its a common issue because the cable is underneath the glued battery. Once the new screen module is ordered there is a good change that it'll work and we can save your data. Note that I don't have to pay for the new screen, since I said that I only want the data back and that I don't need the phone back fully working. So I don't think they suggested it for the sake of making money.
I have indicated that I suspect a hardware problem, but the guy said the motherboard is fine. He continued to explain, that since the red LED is on and the mainboard as well as the battery are fine they assume a problem with the screen.
My questions:
How can they check if the logicboard "is ok" (I asked if they can do micro soldering and since they can't I doubt they can measure the components). Are there easy ways to exclude an hardware error on the board?
Is it possible that the phone doesn't start, vibrate, is not detected by the PC all because of a faulty screen? Any ideas why the LED is visible then?
Doesn't the red solid LED indicate charging? So how come I "charge" while not being plugged in? (LED stays red all the time)
My initial problem wasn't a possibly ruined screen cable/connection but a bloated battery. It just cracked the backcover open but nothing happened to the screen --> Is it possible at all that the bloated battery killed the display module?
If anyone has read this far: It would help me if you speculate with me about the problem, share your experiences or help me in any other way. Somehow I have to pass the time until next week and I'm going insane xD
Thank you so much!
