I have a Motorola Droid 2 Global running CM7. It works fine, other than the usual quirks of a custom ROM, but it gave me a bit of a scare yesterday. Here's what happened:
- Battery was low, 28%-ish, because I hadn't charged it for 2 or 3 days
- Plugged USB from the netbook to charge it (I lost its AC adapter somewhere in the junkyard that I call my home)
- Unplugged it after only a few minutes because I had to go out in a hurry, battery had reached 30 or 31%. Dropped it from a height of about 50cm while doing so; a bundle of wires cushioned the fall (the phone has survived *much* harder falls)
- Stayed out about 20 minutes, nothing unusual to report, phone working fine
- Came home, put it on the desk, went about my business for about half an hour
- Found it blinking red, only noticed because a notification (stupid Astrid Task reminding me I should use it) made the screen light up
- Grabbed it and it was *hot*, hotter than it had ever gotten before and way more than anything this small has a right to get. Battery was down to 1%.
- Fearing a short I panicked and pulled the battery, then left everything to cool down.
Well, a short it wasn't otherwise it would have stopped working entirely; rather I think for some reason all of the hardware was working 100% constantly, though I'm surprised at just how much heat that can put out. There was nothing weird about the phone's behaviour up until this. A software bug? It had a really long uptime, something like a month and a half without being turned off (I keep it in airplane mode at night)... I've heard that Android in general and custom ROMs in particular can freak out if they're left unrebooted for very long. Otherwise it would have to be a hardware problem, but it's a weird hardware problem that leaves a phone working even while it bakes itself.
I'm recharging it right now and no abnormal heating is going on.
W, I ask, TF?
I feel your panic. My HTC Sensation can heat up even from browsing the web to around 40 degrees centigrade Sometimes eve too hot to hold.

Got an Optimus 2x that gets way hotter when using than the Desire it replaced. It also has a cheap Chinese battery which I strongly suspect does not work as it should. Perhaps your battery is giving problems and needs to be replaced or there was a temporary problem with the charging circuitry?

I don't get it. This morning on my way to school, I'm using my Nexus, sending a couple of texts and listening to music, yeah. So then when I get to class I power my Nexus S 4G off, I'm talking about holding power and pressing power off, off.
I turned it off next hour and my battery literally drained itself from a good 95% charge this morning to a 63%. The hell happened here? The phone wasn't even on!

I've seen this a couple of times, vampire drain so long as the battery is attached (phone on/off irrelevant). Never got down to the root of the problem, i believe everyone who has had it ended up calling up samsung to get this sorted as it would be a hardware issue no doubt.
However, do test it again, as follows.
Control Test:
-Take battery out of phone, noting charge
-Sleep
-Put battery back into phone, noting charge
Vampire Test:
-Turn phone off, noting charge
-Take out battery, wait 2 minutes, replace battery
-Leave phone off and sleep (for the same amount of time preferably )
-Put battery back into phone, noting charge
No touching the charger 1 hour prior and before turning on. If there is a noticeable difference between the two tests, call samsung ASAP. Hopefully you're still under warranty.
Definitely a hardware fault

I have exactly the same problem and proved it to be hardware thanks to your vampire test. (This was only after scrubbing through new apps I had installed to see if they were the cause, scrutinizing battery stats, installing a couple of different ROMs, and complete factory resets and everything - nothing solved it.)
My phone was working fine, then one day, a few weeks ago now, I noticed a sudden battery drain and instead of a day's worth of moderate use, it wouldn't last 5 hrs. Finally did the vampire test after seeing this post and discovered that with the phone completely powered off the battery would drain to nothing in < 6hrs. I verified this behavior with two batteries. The phone gets quite toasty as well, so it's got to be some sort of hardware short circuit causing a constant load on the battery.
Samsung said "send it in for repair" - I haven't done that yet, need to find out what that might cost compared to a new phone. (I'm using a company supplied phone meanwhile.)
Too bad, because I loved my Nexus S - perfect size and shape compared to all the new mini tablet phones out there.
Hey all,
I am currently running CM9 (bhundven's 7-29 herring build) on my Galaxy S 4G, and I am having some problems with random shutdown. This has only been happening for the past few days or so (EDIT: and I have been running CM9 for about three months with no issues). It seems that the phone works perfectly fine until the charge gets to about 60% starting from a full charge, and then the phone randomly shuts off. The phone will not start back up unless I have it plugged into the wall, and the results are a little unpredictable. The first time it happened, I turned it back on and it said the battery was at 1% and charging. Now, after clearing the battery stats, it reboots to 60% battery. It seems to work perfectly fine after that, and yesterday it went all the way down to about 12% before I started charging it again. It just happened again today, and when I turned it back on it said it was at about 60%.
My charging habits are pretty bad for Li-Ion batteries; I tend to let the charge drop all the way to about 10% or 5% before I plug it in and charge it all night, way past what is necessary to get to 100%.
The battery does look a tad swollen, but I might be exaggerating.
I just wanted to know if this is a bad battery with 100% certainty, or could it be a problem with the OS or internal parts, etc. I can easily buy another battery online, and I probably will.
EDIT: Also, I have had some overheating issues with this phone, and I can often smell electrical smoke in the charger port area behind the speaker, which is why I say it might be an internal parts issue.
Thanks everyone,

You need a new battery. I was having the same issue lime 3 months ago; phone was dying at half charge the when it rebooted, battery would be dead. Then when I plugged it in, it would charge in 20 minutes and the repeat the cycle. Put the battery on a table to see if its still flat. If it rocks or spins excessively, its usually an indicator of a bad cell.
Mine JUST started doing the exact same thing last week. Battery is definitely swollen. I replaced it just this evening and I'm in the process of doing a full charge from 0->100 to see how things go. I'm 99.999% sure the battery was dead. Replace yours.
Sorry for the thread necro, but I wanted to thank the OP for asking this question and to the helpful replies. We just had a heat wave here and maybe coincidentally to that, I've been having random shutdown problems. Having looked at this thread and my battery, I can tell that I definitely need to replace that. So thanks, all!
My phone is discharging even when is turned off!
Besides it have high battery drain compared to my BravoC, which in stand by last for days.
This Inspire 4G last max 15 hours, changed the radio, and flashed it to reach that, before it lasted ~9 hours max. I'm talking in stand by, not even using it nor data/wifi/gps turned on. I have checked the processor use and it was in deepsleep most of the time.
Yesterday I fully charged it and inmediately turned it off. Today I tried to turn it on but is dead, completely drained. The battery is new and it does have the sufficient capacity, i mean is not a battery failure (checked it with a hobby charger).
I bought the phone on ebay, it has the volume up button dead, so I dissasembly it to if it can be fixed easily and found out that the phone was previously open. Also the screen seems to be a replacemente (a crappy one) since the light bleed in the dark state is high, alsio the light bleed at high angles. This would explain the high drain using it, but not the drain when is turned off.
Anyone have any idea of what it may be? maybe something not connected properly when it was repaired before or a short circuit anywhere?? or is a deeper failure and there's nothing that can be done?
I'm saving for a One X in the meanwhile but i'd like to fox this in the meanwhile since i won't be buying it anytime soon
I set my N5 on my charger (it was at 90%) after lunch and then walked away from my desk. I got back to my desk and saw the LED blinking from a text message so I turned the screen on and realized it was SUPER hot and the charge was only at 81% even though it had the lightning bolt over the battery icon as if it is charging.
Has anyone else had this happen and should I be worried it damaged my phone?? The phone was almost too hot to handle, so I turned it off immediately in hopes it would cool down faster/reduce the harm to hardware.
I've been using the charger without any issues for over a month now, but this might be the last time I trust it.

This is a known issue with the TYLT and the N5: http://forum.xda-developers.com/showthread.php?t=2571188
You can try turning off Day Dream. This will help some.
my cheap ass 21$ Qi charger never does this check it out

I'm really curious as to what's causing this because I've been using the TYLT daily for a few weeks and my phone doesn't even get warm. Kinda nervous to continue using it though.
Wireless charging already can heat up the phone by a few more degrees then using a wire.
People are then doing things such as Daydream or simply running apps which are causing the phone to have a high current draw which could potentially cause issues such as:
-using more power then is being provided
-getting very hot from being both used and charged at the same time.
Welp. Unfortunately, it looks like I can be added to the list of those who have been "burned" by the Tylt Vu. I've been using two different ones for about two weeks now with no issues at all. The hottest my N5 would ever get would be around 37C (but it would usually hover around 34-35C). I've been keeping an eye on the battery temp since reading all these horror stories of overheating. Tonight, it was charging fine when I picked my phone up to check a text and mess around for a couple minutes. When I put it back on, it was probably around 37-38C or so. I was sitting next to it and touched the screen to check the temp, and it felt REALLY hot (only about 5-10 minutes after setting the phone back down to charge). So I took it off and the battery temp was showing 49.5C with "health" saying "overheating". I always make sure the screen is turned off after putting it on the charger, so I know it wasn't in daydream or anything. Kinda freaked me out. I love these chargers, but my faith in leaving them unattended while charging is now shaky at best.

When it happened to me I never turned the screen on during charging either.
And for the record I have never used the Daydream feature :-/
I was excited at first of the premise of wireless charging particularly to cut down on wear and tear to the micro USB port, but now I'm back to the old fashioned way.
So, I have a Verizon Samsung Galaxy S 3 that I got around the time they first came out. It's never gotten wet or really had any problems until the past few months. The first thing that happened was the power button broke and it was stuck down for quite a while before I figured out how to "fix" that. A little carefully applied WD-40 around the power button did the trick. I got a new battery and everything seemed fine.
Lately, however, the charging is not working correctly at all. I'm using the same charger that came with the phone and it will seem to work fine most of the time, but it has problems once unplugged. For example, I'll charge it overnight and wake up to it being at 50-80% battery. Other times, I'll charge it overnight, it will then show 100%, but after unplugging it, it will very quickly, like a few minutes, drop to the ~85%. What happened today though was the final straw. I turned it off and let it charge for about 4 hours until it said it was full. I then took the battery out for 5 minutes before putting it back in and plugging it in again. It then said it was at ~15% battery. I turned it on and, yes, 13% after ~4 hours of charging. I still occasionally have problems with the power button getting stuck and causing a rapid discharge, but I can fix that now and I carry two batteries usually. Not being to charge them though isn't going to work.
I currently live in Taiwan and use Chunghwa Telecom. I constantly have a little notification that says "This SIM card is from an unknown source", but I didn't have problems until months after moving here.
Any thoughts on what could be causing the charging to malfunction and how to fix it? I love my phone and would hate to part with it.
