FRF91 Heat issues?

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!

[Q] Salsa touch response works weird while charging

Hi,
I have this strange problem happening since yesterday on my brand new Salsa. When I put it on charging and leave it on a wooden table, the touch screen responds weird to my touch. The ring lock will not open all the way or shortcuts will work weird. The soft keys at the bottom too go absurd not responding or giving different options.
If I pick the handset (probably providing grounding), everything works normal thereafter. I'm using only the original charger provided with handset.
Additionally even the sound into my car's auxillary port is behaving as weird filtering or dimming the vocal frequencies but allowing the music to get through.
Does anyone know why this is happening?
Only incident to have caused this I guess is when the sales guy I went to plugged the phone onto a blackberry charger yesterday for a few seconds.
Could it have caused some damage to some internal part - diode or something that is leaking AC voltage onto the capacitive screen ? Can I have it repaired at HTC ?
Since it's not even a week old, I'm too distressed about the weirdness. PLEASE HELP!

does seem like it could of done some damage as blackberry's do take a lot more juice than the salsa, personally i would take it back and tell them about the problems you have had only since the dude abused the phone lol

I will surely be taking it back but want to confirm if its the problem with the phone or charger, because I do not see this problem when I charge from my laptops USB.
And I want to know what it is before I take it to them. Its much safer to find the problem and tell them rather than allowing them to figure it out themselves and in turn damage something else.
Thanks

your laptop will deal 5v 1a max before the computer will cut off the usb supply due to risk of overload, new blackberry chargers deal a lot more than that due to the juice the device needs to charge, almost like different laptop chargers the difference in the supply would kill your laptop, i don't have any problems with my device regardless of surface it is resting on.

I have the same problem
I have the same problem, but it was observed from the time of purchase. So do not worry and take the phone in hand))

Resolved
With some searching I resolved this problem or I can say I at least know why this is happening.
It is the charger that is faulty and not the handset. I changed it with another HTC charger I had and the problem disappeared. I figured the most logical explanation is what I read in one of the post elsewhere in this forum.
The charger could be faulty to be leaking some AC voltage along with the charging DC juice. This leaked voltage interferes with the sensitive capacitive touch screen. If we hold the handset in hand, we are providing a natural grounding and hence the problem disappears.
I personally would not like this to continue and so I'm going to take it back to my vendor for replacing the charger or if the need be, buy a new one.

Try using another charger and see the difference. Hope you can get your charger repaired or replaced!
Take care.

this is due to a grounding problem or/and leaked ac current....

This problem occurs when your charger supplies more power than required by the phone to charge.The only solution for your prolem is changing your charger.

I had once another problem, that my Salsa overheated (red-green blinking) when I charged it and my Wifi was on. Maybe a background-process could be responsible.

[Q] Unresponsive Screen Charging

I've been using third party chargers for a few days since my original email charger broke. However whenever I'm using the phone with a third party one the touchscreen is a bit less sensitive and responsive. However, I as soon as I take it out it behaves as normal. I wonder if this happens to anyone else? And also can it cause long lasting damage to the phone?

I too have the same problem.. its not that quite responsive when its charging.. Im using by the way the latest stock LC2.
I think this is inherent irregardless if your using the stock charger or any 3rd party charger for that matter. This issue is not on the chargers actually but on the 'laggyness' on the Note's screen when your using it (while it's charging).

+1 Also observed this when charging from a friend's HTC charger, also read a thread about this a while ago, although there was no definitive answer from what I read, just people reporting the issue...
Sorry mate, no solution from me, but you can be sure you're not the only one experiencing this issue.
I'd imagine it has something to do with the fact that the charger may not be able to supply the power that the larger Note battery needs...
LE: No, charging with its original charger or my S2 charger, or even my Galaxy Ace's charger does not make it less responsive. HTC charger...does

Used to have same problem with iphone too. Cheap Chinese chargers have same effect.

I think from a simple deduction, when your charging, your actually charging the phone's screen itself. Now this maybe wrong but I've read somewhere that what's mainly holding the power on all touchscreen phone is the actual screen itself.
So if your charging the phone, your actually charging the screen and if your using the phone(naturally using the screen itself) you are in effect disturbing the charge because the power it needs to fill up to recharge the phone is being use also to discharge it (thru constantly using the phone itself.)

This is an issue with many android devices. And some do it even with the OEM charger. I've personally experienced it on 3-4 of my phones.

This happened on my HTC EVO even with the factory charger.

Sorry, but this is bull****. Phones have batteries like any other portable device, and this is what is charged.
I am speculating entirely but it is most likely that the voltage coming in from the USB cable is ****ing with however the screen detects your finger (i.e, via capacitive sensing). More speculating but I assume that having some sort of electric field near a capacitive screen will cause issues in detection (I've had the same effect happen with the capacitive buttons near a plasma ball; they caused false detections of the button being pushed). Then again, the phone is full of electronics + radio transmitter so I might be wrong.
Basically, buy a better cable, or it might just be a general fault with this sort of thing.

My HD2's screen used to go crazy when I charged it with a Chinese charger, like random screen touches at warp speed. If I used a well made charger, all was well.
The touch screen did eventually die on the HD2, and I had to send it back for repair under warranty. Now, if I get any jittering/non-responsive screen behaviour, I ditch the charger.

I've experienced this too, but it is not necessarily the charger, but the amount of power delivered by the charger.
I used to live in a rural area and the power supply was bad. We only got about 150V through the wall socket instead of the full 240V.
Using my stock charger on my Galaxy S, the screen was laggy, but if I used the same charger on a good power outlet in town, it was fine.
I've also used cheap no name chargers that are laggy even on a "good" wall socket.

speculation and assumptions are just cousins..
Anyway, you are talking about capacitive sensing and stuffs. Capacitives and resistives only apply to touchscreens and none on qwerty phones. Your 'speculation' about electric fields on capacitive screens are actually correct, but I would like to go back to what I said again, the phone draws power from the screen itself. So when you touch the screen (to perform gestures on it), you are actually drawing out power from the phone. your finger performs a conductance to the screen. Your say of 'false detection of the button being pushed' are actually magnetic fields that is try extrapolate from your fingers (as a magnet) to the screen, thereby causing a marginal errors on the screen's predefine calibration.
That is why you may have notice that whenever you have your phone charge, and your actually using for example to type a message on your phone, you can clearly see a margin of seconds in delay when letters will be registered to your message.
Try to simulate that with the phone charge and when it's not. Clearly you will see what I mean.
this is what the word- ferromagnetism is all about.
anyway, I won't delved with that as it's in the realm of physics already.

Had this same problem on my Dell Streak5 when using a non stock charger. The fix at that time was to purchase the small longitudinal magnets that are made to surround and clamp onto the usb cable. I had to place two on the end closest to the Streak. Corrected 80-90% of the problem.
I got the magnets at Radio Shack. It's been nearly two years ago, but I think I paid about $6 for a pack of 2.

What? Only 150V? I don't believe it. How then other things work?
Sent from my GT-N7000 using Tapatalk

Well I was told it was 150V.
It took a lot longer to charge my phone or laptop there than it did at work in town (using the same charger in both locations), so there was definitely a lower current coming through.

Solved irresponsive screen when charging
After eight months trying to find a solution, today I have tried with my iphone 4 charger and my Kindle cable and, for the first time,I am able to write properly, as I weren't plugged. I have to say I don't like this device, it's very slow and the screen goes green almost everyday.

NICE GUY

Well this problem is not because of screen quality. Its all about with the wavelength of current supply and change in frequency . Its create some magnetic field and makes your screen behave weird. When we get proper ellectric supply we don't face such problems. Also cheap chargers don't follow quality levels and they generate uneven frequency thats why flux created by them makes screen behave weird.

This happened to my old HTC Incredible S (Vivo).
It only happened when the 5V charger was lower than 1A.
Quite strange.
But you could check if your charger has at least a 1A output.
Should be on there somewhere.
The stock Samsung chargers are 1A as well I believe.

Temperature at the USB connector is too high..

My unit is the tencent 128 gig version..May charging port is overheating within 5 seconds after inserting any charger. Tried factory reset but the problem still persist. I've been using the stock charger. Now I'm using the side port for charger. Anyone who experienced this?

I haven't had that problem. Is it only the port on the bottom of the phone or does the one on the side do it also?

I also started getting that error since today morning... It's quite irritating

Recently have had the same issue
I've had the same issue as well, noticed my port smelled like a shorted circuit, also noticed it only occurs when connected to fast chargers (the stock charger that it came with) started using the side port for fast charging, but noticed earlier today that the side port began to give off the same smell and disconnected it before it gave a notification for it. The phone instructs me to go to a Asus service area like there's gonna be a convenient one around the corner but I live in California and according to the Asus website closest one is in New York.

I have the china model(tencent games) 128 gb version same as OP, when the issue first happened the first thing I did was try to blow any possible lint out that could've been in there, I didn't explicitly see any but I did so just in case.

I don't know about the smell but that thing certainly overheat randomly when charging.

I have 2 ROG phones, 1) 512/CN converted to WW version 2)Utimate Edition WW.
Both phones having charging issues. 1 got the overheating message while in my pocket and not being charged. Now only works with non fast charging on bottom port but side still works. 2 I put on charge one night and woke up to it not having charged at all. It's basically brand new and in same situation as the first one, fast charging only through side port and only certain slow chargers work on bottom port.

I am having sudden issues with bottom usb port. It refuses to detect any kind of charger after 4 to 5 hours of being unplugged.
A restart solves the issue and I can charge. But re-occur after another 4 to 5 hrs. Its so weird
Side port is working fine

I have the exact same issue, but mine comes up with the temperature warning and doesnt charge at all.
Haven't tried the side port which I will do later.
Not really keen on sending it back to the place of purchase (I did report it) because they may charge a fee (plus shipping is already out of pocket),
anyone get anywhere on a fix?

I have it too just 3 days after purchased. USB port was short circuited I guess. Seems a latent design defect not an user issue. Mine is global version not Tencent

I have the same issue as well. Sometimes it just writes USB port temp too high, then restarts on its own, but is still overheating. I switch it completely off, then it seems to work. I have this problem mostly even without any charger plugged in... It is occurring since the last update in March-April more frequently

I use a Rog phone 2 ultimate edition and i also experience the same problem. I have been charging for less than an hour when the alarm sounded that the usb port is overheating. Charging port smelled something like a short circuit and tried to charge again on the same port. Now red light blinks and the alarm still on. Now im charging on the side port. But still this is alarming. Considering it is a gaming phone. It supose to endure long and extreme usage.

I had issue with charger and via twinviedock overheating message.... CN 128gb ver on WW... Safe to say after ROG 1 and two ROG 2 broke screen small fall... Not buying again

Same here. Bottom port burnt off, so I'm using the side one now. Hopefully it doesn't get any issues until i send it for repair.

It just happened this week on my phone, exact same problem as others. Short circuit smell the first time the warning appeared. I only knew about it because of a loud 'ding-dong' alarm that went off with the notification.
I'm also getting the alarm and notification when I'm not charging the phone. The alarm went off at 06:30 a.m. today.
Have to use the side port now.

I'm just glad that none of these phones are exploding.

Wireless charging stopped working 4 XL

I see on some sites that users are reporting this and some think that it's related to the security update in March. That seems to be when mine quit charging wirelessly on known-good chargers.
On mine, it intermittently will never handshake with the charger, start to charge then lose connection or never charge beyond a certain point.
Wondering if anyone here is having this problem.

This sounds like the issue people have had with battery connector. There seems to be a faulty battery connector or easy to break small piece. Many have reported this and have had to either fix it themselves, get another unit or pay to get it fixed. Search around you will see what I mean. I haven't heard anything about an update causing this. I have heard that there is a piece that connects battery to phone that breaks easily. I've read quite a few reports of this and how a slight drop can cause it to break and cause charging issues... Read one person put a piece of electrical tape on it and fixed it that way.. idk. That probably doesn't help much. I hope you get it fixed. If you think it's March update and want to rule it out install April update.

On mine, it intermittently will never handshake with the charger, start to charge then lose connection or never charge beyond a certain point.
Wondering if anyone here is having this problem.

Check for a swollen battery. On mine the glass started to separate near the volume buttons. I didn't find it until I took the case off and inspected it carefully. I was able to get a free replacement. There was extended coverage for 4XL battery issues... maybe still available. My issue was not the same as the battery connector issues also documented on XDA.
Erratic wireless charging and swollen battery
This issue is related to the battery, but not the connector issue others are having. About 3 weeks ago I started experiencing erratic wireless charging. Sometimes it would be fine, other times it would just stop for no reason, or not even start...

That was it exactly.
I talked to them and they escalated me to the "product safet6y team" and I'm waiting to hear back from them to see if they will replace it.
I was heartbroken when it lost wireless charging because I really wanted to keep this phone as long as possible and hated that something was broken. It's almost perfect in every way (and no notch or punch-hole.)
I also had the Soli unit go bad and they replaced my phone early on under warranty. I think LG did a great on these as the ODM, but it looks like their component sources were the problems.
Thanks again for the excellent help.

So I was having the same problem. I had to pop the back off my phone. You can see where the wireless charging pad has a spot where it contacts two pins on the phone side. I bent those two small pins slightly upward and put the back back on. YouTube how to get the back off I only used a small pry tool and my fingernail to bend the pins. You don't need to unhook the back. You can do everything with it connected.
Go slow be careful Good luck
