So I thought my FRF91 had issues but now I'm thinking it's heat.
I was using FRF91 with Google Maps Navigation plugged into a cheap eBay car charger.
Within 20-30 seconds of running Navigation, the phone would reboot.
I did this 3 times in a row, and it would reboot.
I went back to FRF85B, and all was well.
Then I was thinking, the phone was pretty hot when this happened, I checked *#*#INFO#*#* and on FRF91 when it rebooted it was like 38C!!!
(Also on FRF85B, the Temp was in F and not C... weird).
Anyways, today I was driving around back on FRF91 and it crashed again (not plugged in) but was sitting on the dash and it got hot.
So anyone know, is FRF91 pretty sensitive to heat that it would reboot if it goes over a certain temp?
Anyone using a "brand" name car charger? Does your phone heat up?
I have a Belkin charger, and when using Navigation you could almost fry an egg on the thing.
same, i typically use nav and stream music in the N1 car dock, thing gets damn hot. wondering if i should put some sort of shade around it on the top ...

I don't know if this would be of any help, but since FRF91, when i charge my phone over USB (plugged on the computer), my phone gets auround 41°/42° C.
For information, it happens on MCR21 with default kernel, and just by letting the phone charging with screen on.
And since there, no reboot at all.
So i'm not sure your reboot prob would be heat related
If I'm running something heavy while charging on the car, I at least point the vent to it and turn it up to blow a good amount of air on it.. If it's hot, I'll go ahead and turn on the AC.
Kinda sucks gas milage, as I almost never use AC otherwise, but keeps the phone cool.
Anyone else have reboot with heat issues? I'm right now listening to podcast, and charging my phone and bam it reboots, then within 2 minutes it reboots again.
I check the temp and it's 38C. I pop out the battery and it's not even warm!!!!! The phone itself was hot. I unplug it and within 2 minutes the temp calls down to 35C.
Anyone got any ideas? This is all stock ATT Nexus One FRF91.
Pretty useless if I can't use the dang phone when it's charging.

Ok good its not only me that noticed the heating issue..charging my phone it gets bananas and using the net is bad as well..going back to 85b
I'm having the exact same issue. Every time my phone gets even a little bit hot, it reboots itself. Maybe it's an issue with the ATT/Rogers N1 specifically, since the only people I've seen who have the problem are on those phones.
Same issue here. Was driving back up to CT from D.C. yesterday and the phone reboot during Google Navigation use.
Funny thing is, when I used it last week to drive down there for the holiday, there were no issues.
Could it have been the fact that it was scorching hot even with the AC running?

I'm using N1 in Indonesia, tropical country with glaring sun all the time
Yesterday I'm trying to use sat nav without charging in the car, yes it was hot to touch
but never reboots, I'm also on FRF91.
But I think if the battery didn't die first it would reboot due its high temp.
I think what we experienced here is result of constant high usage of data + gps

No I have the Tmobile version (i'm using WIND) and it get mad hot..Through charging and anything net related (i only use wifi). As well connected to usb (obviously since it also charges).
My Nexus gets broiling hot when charging in "USB" mode - which you will get plugged into a USB port OR plugged into almost any non-HTC charger. Basically, it limits it to ~450ma draw, and I imagine that HTC didn't engineer this well and some wasted current just gets shunted as heat. This does NOT happen when charging in "AC" mode off of the HTC charger.
That waste heat may be a really stupid engineering problem, BUT, I've had my phone overclocked, plugged in to a 2A charger brick, but in USB mode, incredibly hot to the touch and showing 43deg or more while running graphics benchmarks or games, and I've never seen a problem. If "only" 38deg is giving you heat-related issues, that seems like a defect, and I'd look to get a warranty replacement before the board dies.

completely agree but whats funny as the heat issue never happened with froyo 50-85
Hmmm. My problem is not simply the heat, but the fact that the slightest bit of heat seems to cause my N1 to reboot itself. Anyone having similar issues, or perhaps suggestions on what I can do? I've unlocked my bootloader, but I'm running stock firmware. Hopefully this isn't a hardware issue

This absolutely does not happen. The charge is limited by the power supply, the phone is pretty much "blind" to the source. A more likely cause is the phone is TRYING to pull the .5A of charge and only getting .45A, causing to attempt to compensate and thus running more inefficiently. Also, as far as heat goes, do you turn the screen off out leaver out on while charging the device?

REEEEEAAAAALY?
I sincerely hope that you meant to say that this absolutely does not happen to YOU.
There's been a ton about this, on this forum. There are two pins in the USB connection that, if they are open (like on a computer or with most chargers), cause the Nexus to see itself in "USB" mode, and to not draw more than ~.45-.50A. If those two pins are shorted, you get "AC" mode, and the phone will take up to about 1A.
I use several different bricks with the Nexus (iPhone brick - [email protected], iPad brick - spec'd as 10watt, several different thrid-party AC/USB bricks - all between 1.6 and 2.0A @ 5V, Milestone charger .9A @ 5.9v) and get the same story out of all of them - USB mode and a hot phone (36-38C with the screen off and the phone relatively inactive) during charging. I've never had the slightest performance problem, so I don't worry about it. If I use stock the N1 charger OR one other off-brand (so off-brand that there is nothing useful written on the case other than 2.0A @ 5V) charger, I get "AC" mode - where the phone accepts about .95A @5V, and does NOT get hot (32-34C during charge). This has been consistent with Eclair (stock and several Cyanogens) and every version of Froyo (FRF50, FRF83, FRF85B and FRF91).
My old BB Bold 9000 pulled over 1.5A @ 5V out of all of the 2A chargers that I have - it would fully charge in under an hour without getting hot. My wife's Curve 8900 charges fast as well - so I know that the chargers can do it. It's just the HTC hardware that limits the draw.
I say HTC, because I have confirmed the EXACT SAME behavior on a friend's HTC Desire. He was wondering why it took him all day to charge the phone off of a non-HTC power brick.
The phone is ABSOLUTELY not blind in this - it is the one drawing the current. I suspect that the USB-mode draw is just poorly done (at least on some phones), and there there is some leak. Maybe a specific hardware revision?

That is weird, because it definitely did happen to me (using a plethora of different kernels and speeds). Are you running anything else non-stock (kernel, OC, UV, etc.) that you were not running before?

As long as you've got a running, reliable phone that does what you want and doesn't catch fire, you don't need the highest version number (says the guy who is now running CM nightly builds...).
If you feel like figuring out what is killing off your phone:
First, take a good backup!
Then, do a factory wipe and reload FRF91.
See if you get the same behavior. If you do, it's 91 on your phone. If not, it's one of your apps.
So, if you do not see the "unusual" heating, try restoring your applications and running them like you usually would. Try using a script (if you are up to it) or OS Monitor plus a logcat to see what is eating you up.
yeah i originally put in the old radio and went back to emother's 1.9.2...then put in pauls froyo 50 (which included the new radio). So far added my apps and no extreme heat. Only when on wi-fi but the heat i'm getting was the same i normal got in the beginning and minimal heat when ac charging (before it would get extremely hot). When i come home from work imma try his froyo 91. I'm thinkin it also is stemming from a game Hero of Sparta and a facebook chat app. If i'm correct thats when i first noticed heat issues. but could be wrong i'll let you know
when i have my phone in my car dock i have one of the vents in my car pointed at the thing blasting AC all over it!
helps so much!

Ok, I've been trying to get to the bottom of this problem for a long time.
I've got unilimited HSDPA GPRS on my Tilt, so I tether to my laptop. Kaiser is connected through a 1Amp powered USB hub to a laptop. Tilt was just lying on the desk, and I noticed several interesting things:
1. If Kaiser is at 100% charge - the green light (power) will stay on for a long time, about 40-60 minutes.
2. If Kaiser is NOT at 100% charge, it will charge (orange light) but won't reach 100%. It will stop charging in about 20-30 minutes.
3. If I put Kaiser on a cup, so that there's nothing under it and air moves freely all the way around the Kaiser - I get around 40-60 minutes of charging even when battery is less than 100%. If it is 100%, I can get up to 1.5 hours or so.
4. Whenether it stops charging - I notice that the back of Kaiser gets pretty high.
5. Every 40-60 minutes the charging light comes on again and charges for about 10-20 minutes (gives couple % to battery), then comes off again.
6. BatteryStatus app shows:
6.1 When charge light is ON: + some MAh, don't remember exact number, but it's like 10 or 20.. very low charge
6.2 When charge light is OFF: full battery drain, -400 or somewhere around there (can't remember). It seems that power flow through USB port just stops, disconnects.
7. I see same results when using car charger and stock AC power adapter.
8. Traffic definitelly affects it. If I just have HSDPA on and not using it - it charges fine, it seems. When I start using up the traffic (download files, watch TV, etc) it starts to heat up and stops charging after some time.
It seems to me that the problem with Kaiser stopping to charge when using HSDPA is caused by heat. There must be something on the hardware that turns off charging if the processor/MB/hardware is overheating. I guess charging the battery generates more heat than using the battery, or why else would it turn off charging when overheating?
Just thought that this, perhaps, would be interesting to some developers or people who have the same problem. Maybe someone can put Kaiser in front of a good fan and see what kind of result does that give - maybe it will keep charging.
Assuming that this is true, I don't suppose a fix is possible. Except for, perhaps, switching to slower connection (not applicable in my case) or putting kaiser on a bag of ice.

What does the Batterystatus app read in all above situations?
Since I exchanged my Kaiser, I don't feel the unit getting hot anymore. The previous unit used to get v.hot using wi-fi and 3G/HSDPA - Possible fault?

Scary... I experienced this for the first time last night. Was streaming some vid from my tversity server whilst on the mains charger. All of a sudden my Kaiser got extremely hot. I immediately stopped streaming and let it cool.
I don't think it stopped charging though but I guess it makes sense that it would be protected against overheating.
The only thing I can suggest is try charging with .5 amp... not actually sure that it would charge too well at that though, especially if you're giving it a good workout at the same time.

Try without that 1Amp powered USB hub to a laptop....
1Amp is max i gues... so maby it's giving less, so it take a long time to get from 80% to 100% and yep lot off heat....

I don't use it anymore, but before, if I remember correctly, it showed around small charge (+) when light is on.. then, when phone stops charging it used to drop to full battery drain, around -400 MAh or something like that.
So you got a new Kaiser and it doesn't heat up when using HSDPA? Really?! Have you tried using HSDPA for a long time (actually using the traffic like tethering, MobiTV, etc..)

I see exact same problems when connected to a AC power supply that it came with. Same problem when using car charger.. and same problem when powering by USB without the AC adapter.
Here's my theory... Lithium ion batteries have on-board microprocessors to protect the battery and device from damage. If the battery gets hot the processor will shut down the charging to prevent damage. No matter what tweaks you do to the device or modifications to the charger this on board processor will override and shut down charging if it deemed it was necessary.

No, I said the replacement didn't get hot - read uncomfortably hot - It does get warm, but only in the same way it does when taking a long phone call. My first kaiser used to get extremely hot when charging which indicated a short somewhere. All is well now though.
I hope you can get this sorted though - are you able to get a replacement?

Ahh, I see.
Yeah I think I'd be able to... but mine doesn't get "extremely hot".. it's just.. warm to very warm. It seems normal for me, don't think it's heating anymore than it should.
Have anyone had this problem with 3G (not hsdpa)? Cuz if it happens in 3G as well - that means another reason to be pissed at HTC - they've design kaiser in such a way that you cannot charge and use HSDPA at the same time.
This problem can be easily recreated and a result from other user would tell if it some device or not.
HSPDA with streaming music while charging = warm
HSPDA with streaming video while charging device = Extremely hot
At this point the USB charging will shut off for whatever reason. I just wondering why the phone is putting out that much heat and can it cause problems since I am starting to stream video via HSPDA while charging a lot.

I was just thinking that on some systems it might have interfered with craptive sync. I never guessed that it was because of direct charging issues.
Do you still have problems if you are plugged into the OEM charger, and not a USB port or hub?

Yep. I tried tethering through WiFi (successfully), and same result. Maybe even heats up more, since now there's one more module to power up.

i have an att tilt with the stock rom minus the bloatware.
when i installed battery status (basic version) i noticed that my charging became extremely slow. with the ac charger after the battery status install...it registered +350ma, then it fell to +110ma and wouldn't go any higher, no matter if i soft-reset or not...sometimes it was simply 0. i tried usb connection, ac connection, it didn't make a difference. the charging crawled along slower than i had ever seen it. 39%...40%..........41%. i had enough and i deleted battery status and softreset.
when i rebooted the phone, the battery immediately read 100% (from 41% before the reboot)!!!! and the charging was back to normal.
so my suggestion is to see if removing battery status...and see if that helps?

I never got teathering to work through USB. I'd either teather through WiFi or BT with the a/c charger plugged in. I'd imagine teathering through WiFi would be the worst. Most times I teather I'm just reading email, visiting various forums, and on rare occasions I'm downloading music. I'll have to try later and see what happens while I download music over a teathered WiFi connection...

My Kaiser was absolutely baking last night.
I have a stuck pixel so was using a video that I found somewhere that you play on a continuous loop. The phone wasn't completely flat when I started playing the video but within half an hour or so the low batt notification popped up so I stuck it on charge (supplied mains charger).
I was connected to wifi but wasn't actually doing anything with it (video being played from sd card), in fact I wasn't even using the phone, it was just sat on the side charging and playing the video.
About an hour later I came back to the phone to find it was extremely hot. So hot the heat had travelled right through the phone body and even the screen was hot to touch and the battery was still flat so had clearly stopped charging.
I immediately switched the phone off and removed the battery, even then it took an age to cool down.
I don't know whether to get on to Orange for a replacement... I don't think it's right that it should get that hot.
This has been discussed before but some nice new information is coming out in this thread that ties a few things together.
The Lithium battery does have an onboard charging management system that will stop charge if the battery overheats but also if this heat is combined with high current drain. This should be at a precise point but I have experimented with three types of battery and get very different results between the three AND also between batteries of the same type.
The best performing battery seems to be the latest Samsung (P/N 35H00086-00M) with the external 'X' shaped heat spreader on the back that connects to the four earthing points in the battery compartment. Ealier batteries and some 3rd party batteries have this earthing spreader covered with potting compound or even omitted.
One other item I have found, a 1A rated USB port does not give a continous 1A output. Most ports are only rated at 1A surge and will only give out approx 600mA continuous before IT'S own thermal management system cuts off and kills the USB completely, this is probably the cause of comms loss by some people.
Nice informative thread DarkDvr.
Please, I'd like to see feedback from people on what circumstances people are seeing their phone get hot charging USB. If your phone gets hot on a USB charge, try powering down the phone completely and then charge on USB, does it still get hot?
And please, if your phone gets hot on USB charge, post how you're charging, your ROM, and how hot does it get? There are many applications for this. I use Battery Snap, you can use any program you like. If you don't have a program, please don't guess at the poll, but feel free to post results in a reply.
Also one would assume ambient temperature in the room is typical, but if yours is not (<20c, >28c) please post that information too.
Please answer the poll by the typical range of temperature your phone gets on a USB charge. I'd suggest charging around the 50-60% mark to get more consistent results.. For example charging if the phone is at 95% wouldn't be useful information etc..
One more slight constraint; if your phone gets hot "one time" but not other times, I'm inclined to think there was something else going on with the phone at that time. If your phone is consistently hot when charging USB then post results here.
Reserved in case I need to add any info..
I charged my phone off my Dell M6400's docking station today, started the charge after pulling the phone out of my horizontal case and the phone was 29.5C, I looked multiple times at the highest I saw it was 31.3, and most of the time 31.1. Using Battery Snap for the data. Started charge at 80%, as that's what charge it was from this morning until 4pm when I started I do not have USB Debug enabled by default on my phone, nor did I have mass storage.. When I got the mount prompt I just hit the back button.
Phone is about neutral to the touch, slightly cool. Normally when it's on my desk like this it's fairly cold to the touch, so I'll have to update later when I've put the phone in the same place without charging, but I'm guessing it's a few degrees warmer on the charger than off of it.
I'll repeat this a bit over the weekend here too as I have time, this time I'll set the phone sit on the desk for a while first, check temperature, then charge.
Please do post when you provide input on the poll so we know the circumstances... I mean, if your computer room is 35C and your phone gets 40C charging, I think that's reasonable My office here is around 24-25C.
Charged again today from about 75%, house is around 23C (wife likes it cold..meh) and the phone was 27C max charging on USB.
My AT&T Nexus One purchased June 2 from Google overheats and reboots.
Here's what I've found out:
I charge with the original AC Adapter and this only happens when I'm charging and the battery is LESS than 40%.
If the battery is 50% or higher, it's fine.
When the Battery is less than 45%ish, the phone gets hotter and hotter, from 33C up to 39.3C (is what I last see), then it will SHUTDOWN AND REBOOT. When it reboots, it would be about 37-38C. If it's still under 45%, temp will keep rising again, till 39.3% and REBOOT again, takes about 5-10 minutes for this to happen.
Weird thing is, if you pop the battery out and FEEL it, IT IS NOT HOT AT ALL. It's the DAMN phone that OVERHEATS.
2 nights ago, I was charging and reading in bed. IT DID THIS 3 TIMES IN A FREAKING ROW.
7AM EST, I called HTC, and doing a Device Swap.
Have not received my replacement unit yet. Funny thing is, HTC told me they send out device swaps of JUST THE PHONE, no battery no battery cover. So I have to keep my battery and battery cover. And I told them about my overheat/charging/battery issue, and they said if it still happens to mine, they can send me a new battery.
Anyways I will be testing the replacement unit with my battery and make sure it's VERY low to see if it overheats and reboots.
Other info: This happened in OFFICIAL STOCK FRF91. I'm currently running CyanogenMOD 6 RC1.

Hmm, yeah that sounds like hardware problems to me.. Curious, what are you using to measure? I'd assumed the battery temp stuff was really the battery, not .. something else?
In my case when my phone is cool, the whole phone is cool, not just blindly looking at numbers of course.
Again, would the folks voting really high temps try the things in my first post, and let us know what the ambient temperature of the room is, how hot the phone feels vs the measurement, what's being used to measure it... But particularly I'm curious if totally powering down the phone makes the problem go away.
Dial *#*#INFO#*#* then select Battery Information. It will tell you temperatures there. But I think the temps there is phone temp not batt temp, since in my case when it days 39.3C and I pull the batt, it feels less hot than the phone itself.
Also for my case, it does get hot and reboot while USB charging. Reported 3 time in a row again yesterday and I got pissed and HAD to turn the phone off.
Anyways, waiting for my replacement u from HTC.
Well got my replacement Nexus One today, serial number is higher than my 1 month old Nexus One.
I got it go to up to 39.8C and it did not shutdown and reboot, but stuff started crashing.
Music playing would stop, then if I try to start the song again or choose another one, Music app would Force Close.
Started Navigation app and that right away FC.
Anyone experiencing this?
I think you are using a goofy USB cable, or your room is HOT. Because the only time I've had my phone overheat, I was at a pool, in the sun. The phone's temp was 45 c also. I could still use it, but it was burning hot. An app notified me of the temp (I had it set that way) and I turned the phone off.

I'm using both the original AC adapter and usb cables from google.
Also AC has been on it's under 80F in the room.
The other day on the unit that keep rebooting, when I was navigating, i had to hold it up to the AC vent while i was driving to be able to use it... lol... sigh.
I usually only charge on ac but i think i can easily hit 37-39 while charging for over 30 minutes. Its has been up to 40.5 before i think but there were no crashes or anything. everything was stable (its hot but not enough to be seriously scared or anything)
the room at night is around 24? varies alot but the phone also sits on my bed and/or pillow/blanket. try not to cover it when i sleep.
Hey guys,
Wondering if any of the Hero-ologists here can help.
I have a CDMA Hero, running the most current radio, kernel, etc. Currently I'm running the CM6 nightly with JIT enabled, (Linpack is ~4.9, Quadrant ranks higher than average Motodroid, FTW)
Anyway, I've had the issues below for months now. Nothing changes with kernel, ROM, anything.
From the moment I bought my Hero it's run exceptionally hot. I've come to believe that perhaps it's simply due to the fact that I live in a 1X area, averaging about -100db signal. Battery has always gone extremely fast as well, but that's pretty common.
I have two batteries and an extra charger, and generally I keep a rotation throughout the day, and often I use all 3 batteries. I'm a pretty heavy user (hah, sounds like a drug).
Alright, so here are my symptoms, besides the rapid battery drain:
-Sometimes when my battery states it is somewhere around 20-30%, it will suddenly restart, then it will say it's around 3-7% and to connect my charger.
-Randomly, occasionally, my phone will simply give up charging. This happens plugged into USB, my car charger, or the factory charger.
-When it gives up charging, sometimes the light will stay orange anyway.
-Usually, the LED will instead switch to a rapid-flash of orange/green/2 seconds/orange/green/2 seconds...and so on....and it most certainly is not receiving any power.
Usually I just tolerate the issue. When it happens, I'll swap the battery and it works fine, charges fine. Here are the things I've tried that don't seem to make a difference:
-Battery wipe
-Full battery conditioning
-Ensuring I'm plugged into a USB 2.0 port on the PC
-Swapping to the wall from USB
None of these things work. But it happens with any of my 3 batteries, and when I swap with whichever battery is charged, it fixes the problem.
A bit more storyline here, for record:
When I first got my phone, the battery went so fast, I contacted Sprint. Unfortunately there's no service center for about 120 mi from where I am, and I was too stupid to buy Best Buy's Black Tie when I bought the phone.
They said to go to the local dealer and see if they'd give me a new battery. The local dealer is run by a complete *****, and Best Buy looked at me like I was crazy.
I bought the phone in February, and I believe it's under a 1 year warranty, so perhaps Sprint would swap it for me. I would of course have to unroot my phone, which I'm fine with. But the litmus paper is slightly smudged, and I'm not sure what Sprint would say if they got the phone that way either.
Anyway...that's my story. If anyone has any input, I would be greatly appreciated.
Thank you!
EDIT:
Note that because of the spare charger, normally this isn't a real issue. But I fear things may get worse, and just in case, I'd rather fix this issue now than later. And being that tonight I left my charger and spare batteries at work, my battery officially depleted and I have no phone until tomorrow. And it's like having your crack-pipe taken away.
I noticed this as of yesterday. My Nexus One is plugged in to the wall charger right now, but it randomly stops charging. The light at the top disappears and the phone shows that it is not charging. Give it a few seconds, and it starts charging again. Sometimes it will charge for 30 minutes without a problem, other times it starts and stops every few minutes. I've tried messing with the cable, but it doesn't affect whether or not it charges. I plan on switching batteries with my brother to see if that has a change. I'll also try a different cable soon. I've already rebooted the device, no change. If you go to the battery usage chart, it shows huge gaps in the green charging area..
Rooted, running geo411m stock rom, Android 2.3.3, stock kernel, stock HBOOT.
Any ideas? I hope the charging circuitry isn't failing. Took like 5 hours to charge, now the phone is at 95% battery.
I would try to wipe the battery stats from recovery see if that makes any difference then maybe try full wipe 1 to 5 times and maybe a clean install or even just change ROMs and check if it's the same.
alright I'll give those a try. I just don't know what could have caused it to happen. been on this rom for months, no change in setup. just randomly started. seems like a software issue to me (hopefully not hardware). even right now as I'm using it, it's plugged in but not charging.. 81%, no charge light.

Your charger or cable are most likely the culprit. When the charger doesn't provide enough current - the phone stops charging, and sometimes chargers fail.

I will also try that. I'll switch chargers with my brother tomorrow.

It was the charger! My brother has an official HTC one he bought off eBay (looks like this), whereas I have the one that came with the N1. His charged my phone fine. My charger was still screwing up with his phone. I'm just going to buy the HTC one now. Thanks for you suggestion!

Call HTC, even if you're out of warranty. They have been exceptional in providing replacements for broken accessories. I had somehow cracked the lens in the battery door, and when I called to ask where I can buy a new back cover they simply asked for my address and told me I could expect one the next day. Worst thing that could happen is they say "no".
I was searching an answer but found myself. The issue is something happen to system because of unstable voltage then keeps turning off charging.
I've added agni control kernel and activated ignore unstable charging power and voila!
I know this is an old thread but can you tell me - if you can remember (!) - how did you acticate "ignore unstable charging power"? I have the AGNI kernel for my Xiaomi Redmi Note 5 but no idea where the settings are! I've heard of an app but where it is I don't know.

How did you activate that feature? Where are the kernel settings?
So my HTC One does something really weird sometimes and im afraid if this keeps going on something bad will happen to it.
since i got 5 months ago this has happened like 4-5 times. and i charge it every night. so, sometimes when I charge it and go to bed I wake up and check the phone and even though it was charging when I left it it has only charged for like 20% and even though its connnected to the charger the charging icon wont show. plus the phone is too hot. and i dont mean warm or hot on the back. I mean too hot to touch everywhere, not only the back. Everywhere it has aluminium its too hot. this has only happened 4-5 times and I immediately take it off the charger wait a bit to cool off and then start charging it again and everything is fine. While its hot no warnings pop up and the phone works just fine, but its extremely hot and even though its connected to the charger it doesnt charge. why is that?

Hey,
This might be a problem with the charger.
Try using the original charging set provided with the phone.
Is there anything you do with the phone that may be considered out of the normal when you charge it?
Worst-case scenario, this might be a hardware fault. In that case you should be able to claim it under warranty.
Good Luck
Something similar happens to me on occasion. It'll be plugged in but when viewing in/out mah, it actually shows it's draining. Less than when it was unplugged, but still draining although it says ac plugged in. (using battery monitor to view btw). When it does that, and it's left plugged in (like overnight), it's abnormally hot when I check it. I have to unplug it and then plug it back in (sometimes a few times) before charging levels go back to norm.

It happened on me for 1 or 2 times as well, the only different is mine is not really hot. After i flashed custom rom, it seems everything is fine. I guess maybe there are some bugs in the original rom. Now i am using the rom based on google edition. Good luck
I am using the original charger and it does this but it also have done this with a samsung charger i have used some times. something else that I noticed is that when I'm charging and using the phone sometimes the battery percentage drops.
