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.
Somebody told me some time ago that iPod charger fixes these problems... can anybody confirm that?

My Kaiser would get hot with a teathered WiFi data connection, but I don't think it ever stopped charging on me.

Hmm.. sorry, but, are you sure? Try tetheting through a powered USB and.. I dunno.. do a big download or something, play an online game.. do something traffic intensive.. it should stop charging.. if it won't - hell, please let me know!

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?

That's really bizzare.. I had BS for a long time and never seen any problems, actually.. I just reflashed and haven't installed BS on it (I have no need for it now). We'll see if it makes any difference.. I hope it does.

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.
Guys, I have a problem with my htc diamond.
I purchased it used, and although the seller showed it to me working it started to go all funky on my an hour later. The problem I am seeing is this:
Sometimes the phone does not turn on, I would have to take out the battery and placed it back in, sometimes a few times before i can get it to turn on. When it does turn on, it doesnt last long, sometimes 2mins sometimes 5-10mins. The battery shows 50% charge. THis thing does not want to stay on for more than 30mins! I can not change this thing either, sometimes it charges and than something when i plug it in nothing happens. As well if the phone is one it gets pretty warm for a cell phone. I have never held a phone that got warmed liek this while not talking on it.
Does anyone thing this cell is cooked and i got a lemon or do you think it is a battery issue?
Thanks for any advice.
Don't know for sure, but sounds like it can be a battery issue.
And the Diamond DOES get pretty warm if you have wifi / GPS / data turned on for a while.
Thanks for the reply.
Do you know where I can get a 2.03 diamond gsm rom?
I tried 2 rapid share links and after installing i get an error saying the rom is corrupted...
Rapidshare doesnt seem to work for me too well and i can't download from HTC
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?

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!
I have my htc hd7 for 4 days now and i had no problem with the phone so far except a few hours back, when i left my wifi on (i usually turn it off after using) while i continued with my work on my computer. Suddenly the phone vibrated and restarted itself in front of me, i picked up the phone and felt that the lower back of the phone was quite hot.. Turning off the wifi seems to have allowed the phone to cool and no random restarts thereafter.. Anyone encountered the same?
I used wifi for 4 hours (after that the batt was empty) on my hd7 and it was only a little warm and it didn't reset it self .
No such problem here
No problems here. I leave Wi-Fi on all the time when at home, for many hours sometimes, with no overheating issues or random resets.
Ok.. Must be something else that I did.. Anyway I noticed that the phone has notification LED light for missed called but not for unread text messages. Any1 knows how to enable it?
No problem here either. Use wifi as soon as I get it in range.
Mine does this to. It gets super hot at the bottom especially when wifi is on. Im guess that is where the CPU is or the WiFi chipset. About time to exchange.

I noticed this twice. I plugged it to an ac outlet and it began to sync with Zune on PC. I was adding a bunch of new playlists and after a while I caught it restarting. At first i was excited; i thought T-Mobile had sent out an update or something. picked up the phone to embrace the new goodies and then felt the warmth of the phone.
I turn off wifi now to prevent Zune sync unless I need it.
First, sorry for my bad english..
The problem started a few days ago when my phone started to get really hot.. About 49 C, according to the battary software..
But, it is not only the battery, which is hot.. Its mainly the place left for the camera, if you see the mobile from the behind.. And the screen get hot too.. and sometime the mobile shutdown too..
The battery also acts weird. It keeps power only for 2 hours, maximum, and often less than an hour..
I was using the Cyanogenmod 7.2.0 Stable rom, and thought that was the problem.. So i reinstalled the rom, and it didnt help..
Now im running the Nova HD 1.1.0, with android 4.0.4, and the same problem is still on..
Some ideas, why it is doing it?

I think I had the same problem. I got it fixed after sending my phone five times to a repair center. The problem that I had was a defective motherboard.
I think that HDMI broke the motherboard. After I sent my phone for the second or third time for repair, the phone received a board swap. It fixed the problem. But shortly afterwards I tried to connect my phone to a TV again. It worked OK for a while but then, after some minutes, the signal was lost and my phone froze with a black screen. After that, my phone began showing the same problem as before. At both times I was using CyanogenMod 7.x
So, have you ever used the HDMI-out on the phone? And did your phone freeze/crash while using it? If yes, then I am afraid you have a defective motherboard.
Though I am not 100% that that's the reason
Another issue that the phone had was when the phone was turned off, the phone still sucked power out of the battery, resulting a hot phone.
Now I am afraid to use HDMI on this phone.
