Notice the charging at the same time the battery is plummeting?
Sent from my SGH-I777 using xda premium
I had this happen to me once. For me, I had been using the phone constantly for a while one day. I plugged the cord in to charge it and also kept working on it. I was using apps that pull the battery hard. I could feel the battery getting warm, and I noticed that even with it plugged in, the battery was still going down. I closed everything, unplugged it, let it cool down, then tried to charge it again and it was fine.
Not sure if this will help you; just what happened to me.
edit:
I was using A LOT of resources when this happened. Havent had it happen in a long time.
I unplugged from charger, and plugged back in and now its charging like normal again. Weird. Now, if I could figure out how to get away from the Android OS battery drain...
Typical behavior while charging if being used. Depending on what you're doing, you can expect it to charge slower or actually discharge, as you witnessed.
A couple common issues from other electronic devices.
You are drawing more current then the charger is providing.
The cable is not fully seated so there is either resistance in the
connector, lint in the way, surface corrosion in the connector, etc.
I once plugged mine in, set it down and left it for a few minutes to find it really hot and battery draining while charging. I opened set CPU and it was stuck at 1200. Unplugging it didn't fix it. I had to reboot, but it was fine after that.
Other than that the only time I have seen the battery go down while charging was Netflix over 3G over MHL.

Hey all,
So, was over at the other half's house today. Before I left I asked her to stick my x10 into charge for a few mins. When I grabbed it on my way out I was surprised to see it was mostly charged, then I remembered she uses the wall charger while I normally USB. I understand the limitations of USB ports in charging, but it got me thinking.
Can charging the pack so quickly be good for the battery. I'm more up on my Ni-Mh cells than Li-ion but I would have thought that ~1hr charge cant be good in the long run? Where possible would it be better to slow charge via USB like I have been doing?
TIA,
Scratch.
personally, I have charged my phone overnight using the wall charger every night for almost 2 years and my battery appears to be fine. No temp spikes, no sudden drain

battery drains
I nearly always charge mo phone overnight in a power socket aswell, only on a rare occasion i find the battery drains mega fast for no apparent reason. I just reboot, recharge and turn it on again... it is weird but that does the trick for me sometimes. no clue what causes the drainage, even tho its idle. got an app killer on aggressive so that should help, but i'm not sure its just the apps that drain battery.
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.

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:

How long should our Note II take to recharge from 0% to 100%? Problem with practically all Android phones is that it just takes way too long to recharge. Last night I plugged my Note at about 1AM, depleted all the way down. When I woke up at 7AM, it was still at 70%. Does that sound about right for everyone? I understand that we have a huge battery capacity but the limitation with the microUSB port is definitely there.
no something is not right...my device recharges in 2.5hrs from below 10% to 100%
You using an outlet or CPU?
if CPU, are you directly connecting to a USB port or a hub?
My cpu charges so slowly compared to an outlet.
I'm plugged into the wall using the provided OEM charger.

You tried different outlets?
I would turn the phone off, try dif outlet, try charging it, see if it is any better.
If no, probably something hardware related.
if yes, probably something you have installed then i would just restart from stock.
It takes me about 2-3 hours with the oem charger.

I've been having this problem too, and I can't really pin it down. I'm using the charger that comes with the S3,which is only rated at 1amp so I know that's the biggest factor. However, sometimes it charges to full in a few hours, other times after a night on the charger it will have only made it to 60% or so. The real stumper is that it only tends to drain about 1-2% an hour in deep sleep, so it's not like it's draining faster than the charger can keep up. It seems completely random. I'm ordering a 2amp charger to see if it helps, im sure it will, but I'm just confused by the random nature of this.
Yea something is definitely wrong. Mine charges in about 2.5 hours from near 0%. Try a different outlet

I use the cable the phone came with and I can go from 2% battery life to 100% in about 3 hours. Hella fast, luv it.

Yeah about 2-3 hours is my usual charge time from 20% to 0% range respectively.
I still can't help but feel that that is somehow slow though. Can't tell, it's been so long since I had a small battery I don't know what a fast charge is nowadays.
Going from zero is way different than going from 1% the battery tries to protect itself so it trickle charges for a while. Honestly going from 10-100 should not take more than three hours probably closer to two

not sure if this helps, but do you have light manager installed? I had an issue when I first downloaded it and set it up, that night when I went to charge it it would charge VERY SLOW...I finally isolated the issue to light manager....I uninstalled it and reinstalled and it has been fine ever since. The Note 2 for me now charges faster than any device I have ever had.

Hi,
This is what I have found. Sometimes when the microusb end is plugged into the phone that the phone charges at usb rate instead of ac which is wall outlet. I only have this problem with a standard usb cable in the car. Will change it soon but. What you can do after you plug in the microusb into the phone goto settings then battery and see how the phone sees the charging its getting. It will say either usb or ac. Ac is full charge rate usb is much slower since usb like off a pc or laptop has a lower output to your phone.
If you see it takes more than 3 hours to charge your phone and it says ac in settings then you definitely have a problem with either the charger, usb cable or phone.
Thanks,
Bryan
If you're using the cable and charger that came with the phone, you have a problem. Based on what you reported, I'd say you're using a 1A or less charger.
I just got the phone today, and for the most part the phone has been great.
I got it on 11b, and was able to downgrade it to 10c. I rooted it with Stump, and used Bump! to install TWRP. I used Xposed framework, G3 Tweaksbox, Titanium Backup (a lot of bloatware disabled), and root explorer.
The phone is lag-free after some tweaks and all.
Though, one thing that has been bothering me is the overheating.
At first I did disabled Thermal Daemon Mitigation, then realize this was the reason for most of it.
Next, I reenabled it and it fixed the very hot phone (which caused my phone to constantly turn on and off. Like, it would unlock and turn off.)
I let the phone sit, and it got cold. I placed the battery back in, and used it like normal.
I plugged the charger that came in with the phone. When it was connected via PC, the wire did not heat up. I plugged it into the wall charger, and into the outlet. The adapter became VERY hot, as well as the ends of the cable.
I used my old charger (one I bought on Amazon, it's a pretty new and very good charger) and a different wall adapter. The wire and adapter are fine, yet the phone still runs warm.
I disabled most of the bloatware, and the only app I have that takes up a lot of up power and resources (though it's nothing to the G3) is Facebook.
Due to process of elimination, it cannot be the charger. So it's obviously the phone.
I knew it was prone to overheating (more than over flagship devices (apparently) at least), but is it supposed to run this warm when on WiFi? Seems abnormal.
It could be that I am not used to it.
TL;DR
The original phone charger runs VERY hot at the tips to the cable and the charging block does at well. I changed them.
(Even when not on the charger.)
The phone itself is generally warm, far more than most phones I've used.
Is my device defective, or is this normal for this device?
Some heat worse than others. Mine gets quite warm while playing Ingress, for example. The heatsink on the G3's is reportedly horrible generally.
It might be possible to disassemble the phone and apply heat sink paste or something to help dissipate heat better, but I am not sure.
Also, yours might really be defective.

You may have damaged something. Doing this allows the thermal sensors to reach 120 degrees Celsius and then the phone is supposed to shut down.
Mine gets warm, not hot, when charging. I do notice it charges fast, faster than other phones I've had, when connected to the outlet charger. The outlet charger I have is bigger than most that I've seen. I'm wondering if it's the fast charging that causes this?
Does anyone else think the G3 chargers faster when using a wall outlet than most other phones?

I don't know what happened, but the phone is fine now.
It gets warm, but I am going to ahead that is normal for this phone.
As for the outlet charger, I just use the USB cable to my PC and I haven't had any issues.
The first day I had it, it took forever to charge (didn't use the LG cable), but now it charges pretty fast and only gets warm!

That's good. Mine gets warm just charging, not hot as I stated. However, if plugged in and I start playing a game or something, then it gets warmer, but not scalding hot. Of course, that's if I'm playing the game for a long time.
I still think the wall charger must be charge it quicker than on the PC, but yes, I've also noticed hooked up to the PC it charges PDQ. I like that!

Had SkyDragon's custom kernel since I basically got the phone, so yeah.
It was thermal daemon being changed, reverting it fixed most of the issues.
The phone just gets warm, I guess.
