hi, my battery was really low than my phone turned off. i went home to charge but no charging sign. tried to charge it for 1 hour nothing happend. did my phone just died? or can i do somthing to get it back to work?
also i drained it 3 times the past 3 days, could i have broken the battery becouse of this?
try plugging the charger in with the battery out, and fit the battery after and see if it starts to charge? maybe leave it connected overnight or try another battery if possible.

I'm not an expert, so double check the information I'm giving you, as it might be wrong.
Have you tried to use a USB jig to revive the phone? You can buy one on eBay for €5. Hopefully it will solve the problem.
Otherwise, I don't think that it should be the case, but it is reported that SSD drives can be completely erased when they suffer a subtle power cut. In this case, there is no damage other than the complete wipe of all information on the memory. As far as I'm concern, the phone's memory is quite similar to SSD and other flash memories, therefore it would be a possibility, although it is not likely.
Should it be the case, it's better to seek Samsung Service Centre's help. Running out of battery should never damage the phone, therefore, if you have warranty it should be covered.
also i noticed that after a few hours of trying to charge it the battery feels really colld. could this mean the battery is dead?

normally when you charge a battery it heats up a litle. mine stays really cold
Have you tried another charger, or charginging with the usb lead? Soundlike the charger could be duff.

hi any chance did u solve your problem?
i am having the same problem my voltage on the battery drops down to 0 so it does not charge or power on when connected to a charger.
i had to shock the battery with 5v dc till i got the voltage upto 3.2v than put back into phone than on charge but it still drains out completely. any help on how u solved your problem?
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

Received my WCP-700 wireless charger and twice I have put my phone on the charger and minutes later phone is rebooting and battery temp close to 50C. I have noticed others having similar problems with other phones so I suspect it is a problem with the technology.
Anyone else having problems with the wireless charger?
If it happens again I am ebaying, it may be convenient but at least my usb charger does not cause my phone to shutdown from overheating.

I called up fazle and he says that his phone isnt as well. :bowdown:
I have the same one and mine doesnt overhead.
Surround electronics can mess with the charging and cause things to heat up. Also, make sure the cord isn't running parallel with charger. Check the manual to see what I mean.
Also the farther electricity has to travel, the hotter it gets. Try lining it up better.
I have zero trouble with my wireless charger, same LG wcp700 as you. And I've got a case on mine as well. You've definitely got something else going on.

Mine doesn't do that either. My suggestion is to pull it off of the charger as soon as you're at 100% and don't put it on until you're below ~10%. Magnetic fields inducing current causes heat to be released in the wires and surfaces -- it's something you can't stop if it's happening. I'm sure HTC took (some of) all the necessary steps to lessen this, but it still happens.

I wouldn't be making a habit of waiting until 10% to charge, you should get better battery life over the long term by charging before 30%
My phone becomes warm to the touch when charging, but not hot. I have left it on the charging pad while fully charged for hours and haven't had any issues with temperature.

I VERY much disagree with you -- all of the phone manuals etc. say to wait until the battery is dead until you charge. The higher the battery is when you charge the more detriment to the battery life. With modern batteries, however, it doesn't very much matter because they've been designed to be better about this and you won't get much more time out of your batteries by discharging completely before charging.

There are varying views on this, but I was told never to let a LiPo get completely depleted. Beyond all of that, I feel heat is far worse for the battery. It looks like I am not the only one with problems with the tech, others are experiencing the heat issue:

mine gets hotter than just plugged into outlet but not too bad. not like fire lol
My phone was becoming very hot especially while charging and also during daily use. What seems to have fixed the heat issue is I removed the chin with the battery from the phone. I charged the battery while it was detached from the phone. That seems to have reset something.
Now when I charge the phone while the battery is inside the phone or using it, it no longer heats up.

I detached the battery and 'chin' and tried to charge it. After a hour I inserted the battery and turned on the phone. Battery was not charged (battery % stayed the same).
Can you please say if you first attached charger and then detached the battery (with charger) so it was charged?

No longer hot.
I do this once a week.

Agreed, something is wrong. But nonsense? I don't think so.
I have 2 OEM batteries that I rotate using. Both batteries have the same issue. They get hot.
I'm just passing on something that works for me. Use it or don't. Up to you.

Yes nonsense. I wont use it if it gets hot, could suddenly explode and harm you or other people. So dont do something illegal of risking that.

Hey Guys,
Anyone else experience slow to almost non existent charging speed if the phone has been on for a few hours?
The only way it goes back to charging fast is if I restart the phone while its plugged into a charger.
I have tried using the stock charger and aftermarket ones and different cables as well. Makes no difference until restart.
Chime in if anyone has any idea whats happening and/or how to fix it.
PS: I am unlocked and rooted if that matters.
Is the screen off? Having the screen on during charging will skew the charge cycle.
Does it charge normally when shutdown?
Possible battery, charging port, or mobo failure.
Check phone for any signs of battery swelling.
Same issue here. Got the phone today, charges sloooow by USC-C as well as QI... Although it shows "fast charging" in settings. I will check, if it's better after a reboot.

Doesnt matter if the screen is on or off, I even left overnight and gained like 8% charge.
Battery seems to hold a charge fine, there is no swelling and discharge behavior is normal. Used to charge normally a few days ago.

SOT has it diminished significantly?
Charging at a start temperature above 72°F?
If so it sounds like a charge port or mobo failure... sorry.
Try clearing the system cache and a hard reboot.
Try toggling fast charging on/off 3 times.

Ill have to check the temp next time I am at room temp. I was playing some COD so I was over 80F when I started charging just now. Did not have to restart so maybe its good.

Make sure the port is clean and free of debris.
Inspect and carefully clean* if needed with a toothbrush and a small amount of anhydrous isopropyl alcohol.
Lol, RO water if needed than the alcohol.
Allow to dry completely.
*I live in a dusty environment and even after 2 years never had to clean my C port. However my bdu cargo pants pockets are lint free, not all pants pockets are. In general these ports seem to stay clean but you know how that goes...
Same here. Did someone find a solution?
In my case it just normalized itself after a few days of usage... strange thing was, that the slow charging affected both, usb and qi charging.
Glad you fixed.
Btw maybe intelligent charging. If phone can't detect a time where you don't use it it have problem adapting charging speed. If you change everyday the moment you put it on charge better deactivate that option
If I may continue this thread, I have another question about the charging. Is it possible to disable fast charging?
I only charge at night so I don't need my phone to warm up from quick charge. On my old Samsung Galaxy Note 9 I could do it, but now I can't find the setting.
Thanks.

The only harmful part of the charge cycle on this phone is the top-off, and you can adjust that. You could use a 5W charger but I doubt it would extend the life.
More beneficial is checking other threads for features that may drain (add wear to) the battery.

Simply use a 12 watt or less brick.
Fast charging needs a compatible 25w brick and cable (Samsung). In most phones it has to be enabled. Disabling fast charging is easy... enabling it sometimes is not

The whole point of having a feature is to use it when needed. If I am in a hurry I want to activate 30W charging with a single toggle in the settings. I don't have to bring two different power bricks, one 5W, one 30W, and manually switch between them.
