So my phone overheated with twrp- my phone did not like the version I updated to. I was using a replacement battery- non OEM. When I got my problems solved-I noticed a chemical odor coming from the phone when I pulled the battery and restarted after the initial overheat.
I went back to the OEM battery, got past my twrp problem, and was on a custom rom- Jedi-SofA. Weeks go by and yesterday my bluetooth refused to turn on. I restarted several times and no go. I thought it might be the update of the rom- build 4. When I got home the phone was hot and half the charge was gone in an hr or so. I pulled the battery, the same chemical smell was in the phone again. I restarted the phone and when I got back to it the bluetooth was now on. I could turn it on and off several times with no problems. So something was stuck and overheated my phone.
My question is What is that chemical smell being put out? Is the battery putting out gasses from overheating? It looks fine- no swelling, and it recharged fine and held the charge.
Any battery specialists out here? Thanks.
The chemical smell is most likely a component or solder point within the phone being heated beyond its limits.
I round recommend only OEM batteries, as applying too much voltage can fry things.

Our Cingular 3125 has seen its share of rough use. Our 2-year old got a hold of it recently and dropped it. The casing around the battery broke. Since the battery door would not stay on, the phone wouldn't boot. We sent in the phone (10 days left on the warranty at that time) and they replaced the casing and the phone now works.
However when on battery power, the battery indicator cycles between "charging" and "battery", just like you're plugging in the charger and pulling it out. This results in the external and internal displays turning on and off. It happens only when the phone tries to go into "sleep" mode. As in, you close the flip or with the phone open, you wait until the power saving kicks in.
Its been a couple months since we got the phone back (my wife switched to a different phone while the 3125 was being reparied), so the warranty is expired. I did flash the phone to WM6, but the phenomenon continues to happen. Any ideas?
failure
in this case it really seems like a mechanical failure - some shortcut most possibly.
Maybe someone here has good instructions on disassembly of the phone?
So about 2 weeks ago I was booting into the bootloader and BAM black screen of death. The phone would not turn on, it would say it's charging with the red light but nothing I tried worked. I let it charge for hours and nothing. I had a bad feeling because I was literally just booting into my cwm recovery when it turned off and all went to sh**.
Luckily there was a cheap solution. I knew the phone was somewhat alive because I could see it in adb recovery. (./adb devices)
2-3 days went by no luck charging etc.
I decided to stick a the battery inside 2 zip lock bags and freeze it (old trick)
After 12 hours in the chill box I popped it in and the last bit of juice left booted my phone to the last animation.
I took another battery that fit somewhat from another phone and luckily it booted.
Ordered a battery on ebay and now the phone works perfect.
Don't freak it could just be a battery.
I don't think my battery was dead when in recovery but I have read that a low battery or dead to dying battery in cwm can cause this sort of thing to happen.
Anyways back to flashing
Hope this helps someone in need.
Cheers
I was going to post this later, but thanks for the post. My phone has done this twice and my Evo 4g did this. If you're 20% or lower on battery and try to reset, or power on, it freaks out and doesn't want to turn on. My first purchase after I buy a smartphone is always a backup battery. Ebay always have cheap ones. I just pop off the old battery, put it on the dock charger, and then pop in the fully charged backup battery. My friend has replaced his evo 3D twice already "thinking" he had the black screen of death. These phones just have issues with low batteries. If my phone dies and I put it on the charger, sometimes it won't turn on until it's above 20% again

Helpp!!!!!!!
Dropped my xperia mini and it got very slightly wet.
It didn't turn on when i tried.
I took out the battery, wiped it and put it back in.
Then it booted normally. After a while it shut down.
And it didn't turn on. Then I started charging it after about 15 min of not responding it turned on. It was charging till 20%. Then when i started using it for a bit turned off. Now waiting for it to turn on.
What should I do?
Should I get new phone with warranty?
Or is there solution?
Thanks in advance.
Had two incidents like this, the first incident shorted out my phone (just one second in the water), the second one I wiped dry, wrapped a piece of cloth around it and put it in a sack of rice to absorb the moisture (googled it).
Moral of the story: Never turn on a wet cellphone immediately (even after wiping it dry) lest you want a shorted out unit.
Dunno if doing the latter will make much difference seeing as you turned it on and charged the unit. If it is still under warranty you can try to have it fixed, just don't mention the water incident (though there is a possibility they might find out even after it's dried, dunno really)

Thanks my friends told me not to turn it on straight after i wiped it so am getting it fixed.
Hi everyone! I've a problem that's bothering me since i've bought this phone. Let's start from the first day when my beautiful gs2 arrived and there's no way it would turn on, i tried charge the battery but it didn't work too, it displayed the grey battery logo and then reboot in a loop. Then magically after some hours it started working. After a few months the phone started rebooting or powering off by itself and after a few more weeks it wouldn't turn on or charge like the first day and like that it returned to life after few days. I took it to a samsung point and they changed the usb connector.
It all worked fine for a few months and then here we were again and the phone died and turn to life after few days and also this time they changed the usb connector.
Now it's begun rebooting again and i think it won't turn on few weeks from now.
I've noticed that when the phone reboot there's a vertical drop in the battery charge, almost to zero, only to recharges by itself instantaneously after rebooting. Few days ago the phone didn't reboot but the battery charge went instantaneously from 60% to 10% and then started slowly charging by itself till almost 25%.
What do you think about it? I'm starting to think the problem is the battery chip that control the charge, is it possible? It's integrated in the battery right? so if i change it the gs2 would be ok?
i would personally try another battery.
if that doesnt work, it might be the u503 chip on the phone.
i recently had an issue with that chip after slight water damage (http://forum.xda-developers.com/showthread.php?t=2462207) and noticed the same issue with the battery level, and it not turning on sometimes. tried with 3 different batteries and had the same problem.
got rid of the u503 chip, and its working fine now.
The problem is i don't have another battery. I tried the battery of a friend and it came back to life but there's no way to tell if it did the trick because it's random. The other times one second it was dead and the next one it was working again even without changing anything.
In my case when the phone reboot it doesn't get hotter so i think it's different from yours. More over is still under warranty so it's better not to touch it yet
So I have an odd issue here... I have a tmobile v10 that suddenly stopped working. Can't boot up or anything anymore. Here's some events (not in order) that have happened. I dropped my phone about 6 months ago and cracked the screen. Was fine up until about a month ago. I pulled it out of my pocket one day and it was off. Thought I had accidentally turned it off while in my pocket, so I went to power it back on, but nothing. It wouldn't boot up at all. Thought my battery died so I plugged it in, but again, nothing. for the next couple of days I was able to randomly get it to power up and boot up to the main home screen. After a few seconds it would freeze and then shut off on it's on, sometimes rebooting automatically, but never making it passed the "LG" splash screen. Any who, before all this the phone ran fine, no issues. I didn't update anything or add any odd ball apps. I got it to show some life when plugging into the computer via the lg usb cable with the battery removed, but as soon as I threw the battery back in and try to reboot, nothing.
The other odd thing I noticed is that when I threw a charged battery in it, it would kill the life of the battery (verified by placing a charged battery in the dead v10 and then after trying to boot, removing and placing back in my good v10 and checking battery life). It would always say it was either 0% or 5% when I put it back in the good v10. The batteries will still charge on the good v10 so I don't think the batteries are bad (one is a brand new LG brand battery).
I'm leaning towards the prongs being shot on the battery connector that's on the motherboard, rather than the charging port. Anyone ever have this issue or even hear of it? I did some searching online but realized I didn't even know what to look up to find what I was looking for.
Any help will be greatly appreciated and thanks in advance.
Sorry for the story, just trying to give as much details as possible. I'm sure I forgot some stuff, but I'll edit/update as I remember them. Thanks.
