[N7100] Overheating Issues? - Galaxy Note II Q&A, Help & Troubleshooting

I believe I am facing an overheating issues on my N7100 while charging - the battery temp will go up to 38°C or even 39°C if i constantly check my messages and email during the charging period. I done nothing to the CPU nor the frequency and no overclocking app install.
During my normal usage, temp fluctuate between 28°C and 31°C, and that of course depends on the whether and usage activity. Is it normal for N7100 to get to that high temp? My phone will get very hot especially on the top (speaker) part.... be it during charge through the main power plug or power bank.
However, if i leave it there for it to charge. The temp will remain between 34°C and 35°C which i think is hot too. Anyone mind to provide me the correct temp scale for me to follow and take notice of for N7100. Gracias!

Underclocking artemis, worth it?

I've set tomtom to run at 175mhz using batterystatus, will this help battery life at all?
reason being is today the sun was heating up my car nicely, and my phone was running at 40c which i thought was a bit hot, so i thought i'd try running it a bit slower withtomtom open since its sits in the sun directly all day when using it, set it to 162mhz but noticed sometimes it just didn't seem smooth, set it to 175mhz, seems perfect!
Another side affect i've noticed, although i'm not sure if i have a faulty charger, but when the phone was set at the default 200mhz charged fine, after 15 minutes of driving with the phone clocked at 175mhz my charger stopped charging the phone, and i seemed to be able to smell faint electrical burning from the charger, would underclocking/overclocking affect charging?
also, does running it 25mhz slower have any impact on battery life? since my charger has now died wondering if it'l give any noticable gain in battery, just hoping it helps keep it cooler
Clocking does not effect the process of charging, only the time the battery lasts. When you connect your device to a charger and the battery is full, it won't get more charge from the charger, this is software regulated, so the battery stays full and the phone runs on AC power.
For your purpose i would check if the device is any cooler than it was with 200 mhz. I strongly doubt, that 25 mhz less CPU Clock have any major effect on Temperature or Battery life. If in your case your device runs longer and stays cooler, just leave it that way if you do not experience any performance problems, but i think you might as well clock it to 200 mhz again.

Battery temperature constantly rising to over 45.C

My battery temperature rises to almost 45.c+ after a few minutes of HD gaming on my Stock HTC WFS Rooted, Is this normal or theres something wrong with my battery.

the phone has to heat up especially when you play games that use a lot of cpu and gpu...
but idk is it normal to heat it to 45 and more... i think that 50 degrees is a MAX that may happen, and that reffers to battery heat? I mean its just going to shorten life of battery, extremely ... and about processor i think u dont have to worry... it can stand some heat ... i have read that temps went over 70,80 celsius on the phone, and they were still running fine. Of course its not recommended, as you can guess
I don't think that it will be a problem. I have my phone running that hot for four months already when charging, and when not plugged in it also easily reaches 40c. When I dial *#*#4636#*#* my battery health is still good. Also note that on the back of the battery it says that the max operating temperature is 60c.

Never looked at the back of the battery that closely, that clears my doubts.

G4 warm while charging

So I got this phone 2 days ago and I love it except for the battery.Anyways,the battery temp while charging is 34c is this normal?(37c while writing this in chrome)And I noticed that battery drains pretty quickly while gaming(like clash of clans)and hot from the back-top.So is this normal?n
Yes, this is normal. Having the screen on while charging will make it even warmer. Be aware that the phone charges more slowly when the battery rises above roughly 90F/32C, so keeping the phone cool will help with charging speed. Mine will drop from the max of 1600mA with the stock charger, to about 300mA, as the temperature reaches the low-90's F.
Thanks for the reply!
Yeah I noticed that.When ive put the phone in an air conditioned room,battery tempreture decrased to 31.5c and the voltage increased to 4300 mV.But I did a research and found that li ion max voltage is 4.2v anything up is dangerous unless the battery got some sort of overvoltage protection.So should I be worried?
No. Mine charges to 4.4V. I'm comfortable that this is a safe value for the battery.
If LG had it dangerously overcharging every single battery, that would be incredibly irresponsible. I'm sure they picked a safe voltage.
Guys - what app/s are you using to measure. I use Ampere but is there any better?
Thanks.
Just go to the hidden menu by dialing *#*#4636#*#*
That doesn't show the charging Ma?

Stupid battery question

Does a bad battery cause spike in Ma or that's in hardware my battery is shot considering it goes to zero when I open camera at 30-40 percent
It doesn't spike in mA if the battery is getting older and you need a lot of power the Voltage can drop. If the Voltage drops below 3.3V the phone will shut down.
The Problem is that the voltage drops extremely fast so almost no logging software can log that, and it's gone after the crash anyway. So except external Battery monitoring hardware thats quite hard to proof.

Question Charging issue due to phone temp?

People keep saying that their chargers are not working. I noticed via AccuBattery that once my phone exceeds 100-104 F, that the phone stops charging until the phone cools down. I don't think this is a power brick/cable issue, I think this is a thermal management issue.
It's done to try and protect the battery from unnecessary stress and possible damage.
Optimum Li charging temp range is 82-99F
A start temp of 85F is better.
Never attempt to charge below 40F
Avoid starting charge below 72F
Fast charging will likely not engage if temperature is too low (around 71-50F or less).
Charging will disengage if the battery gets too hot about >103F.
Fast charging may disengage at 100F and will start ramping down around 80% and ramp down even more as it approaches 100%
