My sister just texted me asking about random shutdowns when she leaves it to charge overnight. She noticed that in the morning the phone is off, and fully charged. Not rooted or anything, new, two week old stock phone with the stock AC charger in the box.
Could it be overheating and turning off? Is there a temperature history monitor she can turn on and check? Any other suggestions?

I've been having random shutdowns as well, but it usually happens in the afternoon when it's been in my pocket while driving and such. I was running the stock rom rooted, then switched to plain jane v1. Issues with both, so I think it's a heat thing. Just my $.02
I have not had that problem, yet, I charge at night, sometimes I leave it on sometimes I turn it off.
But I had a thought. If she were to charge it while it was standing up on its kickstand, there would be better air circulation and maybe that would help keep it cooler while charging. Might be enough to stop the problem.
if it's bone stock, the phone has a weak cpu that can't tolerate standard operating temps. she will have nothing but problems with it. tell her to return it to VZW and get another Tbolt
this piece of crap phone started to go worser by the minute.
First, it heats up the battery whenever i use wifi or 3g and it will also shut down. Switch battery and it will last a bit longer then still shut down.
Now, it give me this problem where a 91% charged battery would turn out to be red under 5% once insert. The battery indicator will recover slowly over time for no reason.
And i am also having trouble charging the battery by phone, if i charge the phone by usb when the phone is ON, the phone will heat up and turn off and continue to heat up for infinity until unplug.
I don't know what should i do with my x10 anymore... i am not paying out another 700 bucks CAD for a new phone in canada after just 1 years use *out of warranty*.
anyone have a fix for these? or know how do i revert back to 1.6 android?
Where is justice! Samsung should crush Sony already.
As the title would suggest, my poor GS2 gets VERY hot when charging. Not all the time, but often.
If I charge from my PC's USB, it doesn't, but when I use a mains charger, it overheats.
When I finish my night shifts, my battery could be down to 20%, so when I go to bed, I plug in the phone, set it's alarm and pop it under my pillow, like I have done with every phone I've ever owned without issue. I wake up during the night and pull out the phone to check the time and almost leap out of bed because of how hot the device has become.
To make matters worse, it's discharged in battery power. This morning was the final straw, as when I checked the phone and it was red hot, it was also dead. I held down the power button and booted up the phone. It showed 15% battery left. I know people say that when it's charged, remove it from the charger, but it isn't practical. Besides, I've never had to do this on any other phone I've owned. This is unacceptable for me to rely on any more. Is this a common issue?
Or my fault because I have rooted the phone the tried custom roms/kernels/modems on it before?

1) change to a diff kernel and see for the issue.
2) well charging from 10~20% to full 100% will lead to heat up the phone than charging from 50~60% to full 100% , hence also check for the same and see

I should have mentioned. This happens on any Rom and I've tried 4 kernels and still the same issue. Only thing I haven't tried, is going back to Samsung stock rom. Going to try that today, see if that solves it and report back.
Like Samsung told my wife "when it gets hot dial *#*#4636#*#* and note the battery temp".
Is it still under warranty

Well the PC's USB output would be limited to .5 A whereas your wall charger could provide 2 A. This might just be normal IMO, although I can't say that my phone gets ridiculously hot during charging. As others mentioned, I would check the battery temp.
The issue is already in his post and the solution as well.
1) The S2 has the tendacy to get hot. Its all very compact and there are no internal ventilators so the S2 dissipates heat to the rest of its body.
2) There is a Power difference between the charger and a USB cable. The charger gets hotter since it delivers power directly of a higher voltage and slightly higher amps then a usb port.
Your issue comes from one sole thing. Your bed. beds have very poor heat dissipating abilities, in fact, it has none. Considering no fresh air is delivered to your device, because it is stored under your pillow. Not to mention your pillow, the rest of your bed stop heat from leaving and it builds up. Ontop of that your heavy head is resting on it, pressing the pillow tight around the device.
in short, it has no way to relieve the heat. There is a simple solution of a non technical matter. Don't put the darn device under your pillow.
(the same counts to people that use there laptops on there beds pillow or covers without a proper cooling matt, before wondering why the hell there device shut down all of a sudden.)
The problem is you put your phone under your pillow. I made this mistake a few weeks ago and the phone was too hot but no problem when i charge it somewhere not under the pillow
I agree, I should stop doign that. But one question, if that's the case and the getting hot is normal, then why did the battery drop from 100% to 8% while plugged in?
Your cooking the battery, thats why.
i'll admit i charge my phone and leave it ON the bed so air still circulates but it did used to get hot. Not sure if any changes i've made such to things kernel, ROM, modem or undervolting has caused my change in temps but my phone never feels warm anytime day or night weather its on charge or not where as my partners phone (stock sgs2) does get hot using the same charging habits as myself

Another odd issue. If I mains charge my phone or connect it to my laptop(not PC the PC charging seems to not effect it) the phone lags. Menus take longer and it really struggles to register my touches on screen.

For the AC charger this problem is known: if the charger is of poor quality it will generate too much 'noise' (ripple) which disturbs the electric field used by the touchscreen. However the original Samsung charger is of good quality and does not have this problem.
Experiencing these kind of problems when charging by a laptop USB port however is abnormal.
Interesting.
I bought an official Samsung charger off ebay, and it produces the same results. Much to my frustration.
Leaving it plugged in all night however was fine, I placed it on a shelf and the phone was actually cold when I woke up. I'm just worried the battery is ruined. It seems to drain quite quick.

Another problem i faced recently was the battery draining to fast, i was told to pull the battery out for atleast 3 mins, this lets the CPU etc cool off, since then i've had no problems at all and getting a good 12 hrs atleast on battery use

I've had my SGS2 for quite some time and never really had issues until recently I suddenly started seeing 'drive mode' appearing on the top left corner of the screen - the phone behaved erratically in that whatever I was trying to do, drive mode and vlingo would keep popping up. At the same time this started to cause the battery life to drain rapidly - on a full charge and in flight mode the battery lasts about 7-8 hours, before this I'd get more than a day easily on sensible use - there's also the issue of the back of the phone feeling abnormally warm (which i think is causing the battery life to drain). The phone also doesn't get picked up as a storage device on pc, if i charge it i get various issues like voltage being too high or the battery icon showing a warning triangle and sometimes the battery icon is flashing. I've also tried a factory reset - to no avail. Has this happened to anyone? if so what did you do to get it fixed? Some times when i swithoff my phone, the phone will automaticaly restart. Even in swith off mode also the battery charging symbol is coming. And i had put my screen light to 15 seconds after inactivity.. Bt it is not getting off.If I check the battery details it is showing 79 or 80% for screen... Can anyone tell me the reason?????? How can I solve this problem?????
So this is the second time I noticed battery not charging over 80%. So those who put the phone in the water noticed moisture detected and can't charge. Samsung put a monitor on the charging port. So I'm guessing this monitor noticed phone is 2 hot from being in the sun. It got to 80% and that's it only says fast charging with no estimate. If leave it with charger it still won't charge and phone remains hot. When phone cools down it'll go above 80. I tried turning off while phone still hot, and still didn't charge

Probably a safe guard after the Note 7 mess.
