I am running CM 5.0.5.3.
I charged my phone over night while I was asleep for 9 hours. When I woke up, I was unable to hold my phone because it was so hot. I have a screen protector and the screen was not hot to the point where I could not touch it so I checked the battery temperature, and it was 58c. The track ball lights were flashing both green (email) and cyan (text). However, the cyan light was altered; it was instead very dim and looked a bit like dark blue.
I then held the power button to turn off the phone and removed the battery. I turned back on my phone 5 minutes later and everything seems to be in working order, even the cyan light. The battery is at 73% though, after I just unplugged it from 9 hours of charging.
Am I looking at a defective phone? Buggy firmware? Poor settings?
Charging the battery usually heats up the batt, but thats too high. Try setcpu from market first and set up a battery failsafe, 58c is VERY high! You can also try Pershoot/persiansown - UV kernel.

Damn! 58! At least now we know that the N1 will survive up to at least 58C! Holy, I get nervous when the phone reaches 41.

yeah I'd set up some custom stuff in setcpu.
Also, since it's asleep, make sure the phone is underclocked to the lowest and on charging put it at the lowest.
I think the OP is wondering why the phone even got that hot in the first place. Weird...maybe if it happens again...call and get a replacement.
I also have the same problem.
When the phone is hot I also can also see in battery statistics that about 80% of battery life was drained by Android system.
After reboot my phones goes cool quite fast, so I think it can be software problem.
The interesting questing is if it is the battery pack that is damaged and gets to hot during charging (in that case i would rip it out of the phone right away) or if the phone is using all the power.
I guess you could try to rig up an ampere meter between the bat and the phone...
Did anyone try to run the phone without the battery in, running it from the charger? If it gets still hot, its a phone problem.
Update:
when you log into the phone via adb and run "dmesg | grep batt" the phone prints out how much amps it gives or receives from the battery. when the phone gets hot the next time, plug the usb port in without booting and pull the data. after that you can reboot it.

So normal discharge rate when idle is below 10mA. Plugging usb in charges it with some 300mA at about 80% charge level (slow charging as indicated). additionally charging will get slower when the battery is nearly full, so at 20% it may be pulling all the 500mA out of the USB port. The charger is rated for 1000mA I think, so there should be some "charging FAST" message or so.
please post what you phone shows
EDIT:
nope, doesn't work without the battery, just flashes the charging indicator orange and green, to bad. who designs theese things?!

After I read several infos about this topic ...
Is that true that the Nexus S has limit of the amount of power it takes from the wall charger?
Suppose, it has limit of 750 mA.
Even if we use 1000 mA or 2000 mA, the Nexus S will take 750 mA during charging.
So, having much bigger mA charging rate will NOT speed up the charging time.
Am I correct?
Yesterday, I checked my Nexus S during wall charging:
65% charged at 01:57
87% charged at 02:48
So, it is about 22% per 50 minutes.
100% = 227 minutes (3 hours 47 minutes) ... almost 4 hours.
No task was performed, except turning on screen to check batt %.
And I was using HTC Desire charger (5v 1000 mA).
How long is yours?

Using an iPhone (1000mA) nubby it takes sometimes over four hours to charge mine
It definitely seems limited to me - though it seems that 1-2A chargers do cut 10-20% off of the charging time of the .7A stock charger. I said 30% in another thread, but further testing indicates that's not the case. Maybe the limit is around 750 or 800mA, and the stock charger doesn't really give .7 ?
if you want to charge the battery real fast
don't charge inside the phone
use a Wall charger for the battery, and it charges 100% in a little over 2 hours
the ones you find on eBay or Deal Extreme
find the ones that charges at 1000 mAh
you wont find any wall chargers for 2000 mAh (only available for cars)
the highest i've seen for wall is 1200 mAh
in my case it came in a combo so i got 2 extra batteries + wall charger

Could you share the ebay link please? Thanks!
Any idea if this works with the note? seems like a nice deal

11000 mAh??? Uhhhh....
I've got a nice one, about 39 euro in the stores, but only with a 1800 mAh battery
It charges untill 50 % of the Note's battery...
Specs:
Varta V-MAN Power Pack Type 57054
3,7 V Li-ion battery
1800 mAh
6,7 Wh
Input 5V 500 mA
Output 5V 800 mA max
You can try the 2000 mah Energizer XPal XP2000.Around USD$25-30. It's what I use
How about this one.. but not portable..
4500MAh
http://androidcommunity.com/samsung...extended-battery-kickstand-included-20120103/
i am using an app called battery monitor widge from the play store t and have logs for the past day .
its showing different values when charging with the stock HTC charger.
Not sure if the phone or battery circuit does this , it seems the charging on the htc charger is on/off... like charging in pulses
sometimes +600 mah, stops , sometimes _ +300 mah stops , sometimes - xxx mah ...
i think its trickle charging they say the phone trickle charges after 80%. but the prob here is on the HTC charger the charge is fluctuating even below 80%
i tried a note 1 charger which has the same rating as the HTC charger. same behaviour
so it tells me the battery does not like 1A
then i switched to a 700 ma samsung charger . so far it shows a constant current of 800 mah...there is no on/off behaviour
and there is a constant charging current applied except that around 90% onwards the charge tapers off
I seem to recall reading something on the web a long time ago that said that charging at less than 1C could actually result in a faster charge to 80-90% charge.
The rationale being that if you charge at a higher rate, it forces the voltage up to the maximum faster and then the charger has to ramp down the current faster.
If you charge at say 0.7C then it takes longer for the voltage to hit the maximum and then, counterintuitively, the average current for the duration of the charge is actually higher.
I am tested this theory now... but it seems like it could be true.
using samsung charger rated @ 7C and using the battery monitor app, the samsung charger is keeping the phone charged at a constant 700 mah but the HTC charger is fluctuating from 500+ mah to 600 mah ten sometimes to 900 mah
not sure why the samsung charger seems to charge the HTC one faster than the HTC charger..
cant explain why though
They say there are different chargers behave differently with different batteries.
can someone care to share some light here?
is the HTC charger defective?

Even I will like to know. I have been using the blackberry charger for charging my HTC one. The charger is rated 5V, 700 mA. Is it safe to use it permanently with HTC One.
So, In Marshmallow as you all know by now we get to see the MAH of usage. So bascially I was doing some investigation.
Turns out my SOT at 50% was 3 hr 30 min, at 430 MAH
And screen usages 51% Rest of android 49%
And When You calculate 50 % of 3000 MAH you get 1500 MAH obviously.
SO, I added all the usages in battery usage included Screen ON Power 430 MAH . i get 835 MAH
SO MY Questions is where has the rest of the 800 MAH gone??
why my dash charger is slow sometimes is in 3500 ma and sometimes is in 2400 mah , it happens also when I have 30% or 50%

Cool down phone..
I have seen this as well depending on the plug is turned. I get dash charging on one side but slow charging on the other.
