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?

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.
Hi !!!
My Kaiser (Schap's lite 4.31) randomly stop charging, whenever it wants, at home (USB to computer) or in car (as GPS use for example)
With my laptop, i use my Kaiser for "Internet Sharing" to get HSDPA, the orange led stays for a while, and without raison, it turns green and blinks, as stand by mode. So battery decreases very fast. The only way to solve is to stop "Internet Sharing", then ActiveSync re sync, and then led shows orange charging again. Then i can start "Internet Sharing" again, but for how long ? Problem comes again and again...
In car, same problem. In GPS use, with car charger (brand Motorola), it starts Orange charging, and randomly, orange led stops and i'm back with green blinking, running on his own battery (but linked to car charger !!!)
With AC Charger, no charge problem.
Probably my Kaiser has charge problems while running apps ?
Somebody can help me ?
Well I have noticed this same behavior with my Tilt with various
roms. (Stock, Dutty's and now Garmins) It seems to me that at
the time the Tilt stops charging, the device is pretty warm. It
happend when tethered for ICS or when used as GPS. I may be
wrong but I have come to the conclusion that it is designed to
stop charging when the device reaches a certain internal temp.
Just using those two particular applications (ICS w/HSPDA and
GPS) causes the device to heat up, Combined with charging I
think it may be too much and the device stops charging to cool
off so that there isn't a component failure due to the heat build
up. I also say this because after an idle period with ICS (say I
am reading a long article) and the device cools a little it will start
to charge again. Likewise in the car with GPS.

This can help your problem to resolve,go to settings-system-power,make sure when device is turned on do not charge battery when connected to the pc,is unchecked.

@ Darkhynde : You're probably right !!! Last time i saw this non-charging behaviour, it happened after long GPS use (started on its own battery, summer temperature, hot in car, and it stopped charging 5 minutes after switching on car charger adaptor), and long, long HSDPA (more than 5 hours on USB) use.
Temperature must be the answer, you're the king
@ korakesion : Obviously option is checked
Thanks guys !!!

I've used my Tilt as a tethered USB modem during several disaster recovery tests for periods up to 14 hours and I've never had it stop charging.
But I can see the part about GPS because my phone gets hot as hell after 30 or so minutes with GPS running; still charges though...
100% Confirmed Temperatures is the key...
Not sure anyone is still reading this post... but I just want to let yo guys know that I have the same problem... (it stops charging when using internet sharing and it get really hot)
The only solution I have found is to put the Tilt in front of a fan... If you put the tilt in front of a fan... you can use internet sharing/GPS 24/7... done this a million times... and it works for days without a problem.
Hope this helps... take care everyone...
I've had my phone since October 2007 and have tethered with it pretty much everyday since dial up is the only other solution where I live and NEVER did the phone get hot or stop charging until yesterday. If while I am using ICS and I go into power settings and check don't charge while connected to PC and then immediately uncheck it it will charge for a few moments and then go back to flashing green. I put a new battery in and no difference. I hard reset the phone and tried ICS without loading anyhting on the phone still same thing. It charges any other way except when using ICS and I DO pay for tethering on mine.
Just an update to my situation. I plugged my phone into my other computer and used ICS and this time it charged until full (granted it was almost full already) So here I am on my laptop which it would not charge while using ICS and so far after about 10 minutes it is still charging. Only thing I did was poke around in the registry looking for some magic setting but I never changed anything. I don't know if leaving it on a wall charger all day and night did something or I just got lucky. Hopefully it will continue to work since i only have less than a month left on my 1yr warranty.

Doesn't this affect battery-life? I was under the impression you should not charge until the battery is (nearly) empty?
I have a feeling my hermes battery got wasted because the hermes starts charging every time I connect it to my pc (which is every day during office hours)
It's a defect. HTC sucks and I'll never buy one of their phones again. How disrespectful of them! I bought the phone hoping to use it as a modem permanently and go home to find the device heats up within 1 hour of usage and stops USB charging! I can't remain online for more than 2 hours without leaving the air conditioner on. What about the 3D display driver? No drivers! Down with HTC!
99% of the time, i charge my phone over night when im sleeping, however everytime i do this i wake to find my phone has frozen. This means anyone who has tried to call or txt me during the night hasnt gotten through. The phone rings for them, but at my end the phone just stays blank.
This is the only time my phone freezes (within limits) and the fact it happens every night without fail seems a tad odd.
My old kaiser did the same but iv started to get a tad fed up of this, does it do the same for anyone else? Or does anyone know a way around it?
Im running Dutty's 6.1 hybrid, on UK t-mobile.
cheers guys

Is it plugged into a PCs USB port, using a mains charger (if so is it the official one supplied with the device)? Have you tried swapping charging methods (or chargers if you have a spare) to see if the problem goes away? Do you have a spare battery you can swap in?
thanks for the response!
Its an offical HTC charger plugged into the wall, and as far as i can tell charging it via the computer is fine, but then again i dont leave it plugged into the computer for 12 hours.
I dont have second battery to try but the fact that this is a totally new phone & battery and i had this problem with my old phone aswell. iv also swopped the chargers around and it still happens.
are you in wifi mode
Sometimes when I leave the wifi mode on it will freeze, make sure the wifi is off at night. Hope this helps.
Cheers
cheers, wifi is always off though!
Kind of bugging me, especially is id like to use the alarm on my phone, but im too hesitant incase phone freezes & it doesnt go off.
Time to give it an overnight charge from the PC and other tests

The next step then is to restore the phone to an 'as new' state in terms of software/ROM/Radio/spl etc (unless others with the same setup can verify this problem never happens for them) and charge it for the normal period solely via USB from a PC. You mentioned you don't normally recharge the phone this way for long periods but try it for a night or two just to see if this makes a difference. It would also help to rule out power fluctuations as a contributing factor if you could power the PC via a UPS. As this has happened now with 2 phones and 2 mains adapters, its extremely unlikely to be a hardware fault and more likely something associated with the configuration or your neigbourhood power supply. If it locks up most nights, take a note of the time displayed on the phone when that happens - is it the same time on each occasion?
What happens if you leave it on charge while in flight mode with all 'options' such as wifi, bluetooth etc turned off (just for diagnostic purposes)? If you can get it to charge properly without locking up in a basic state, then if you reintroduce any differences one by one and test after each change, you'll find the culprit.
I am trying to setup USB tethering on my phone. Instead of bringing the old threads back from the dead I just linked them below.
First lets get the obvious stuff out of the way.
1. I do use wifi tether, but if I want a file to download all night this isn't a good solution, battery goes dead after about an hour hooked up to the wall charger.
2.PDAnet - this works well if you have time to constantly monitor the connection or for casual surfing on a dead or close to dead battery, it randomly drops and doesn't reconnect on its own.
3. AziLink - The OpenVPN thing ruins this option, to big of a pain in the butt. Having to install an run in a VMAppliance.
I have looked at the other 2 options for USB tether. -
The Race condition between Mobile Network Connection and Mobile Network sharing here I just can't seem to "beat the clock" the network always connects first and gives me error 67. I was thinking this may have been patched since the thread is old, pre-update.
And this other one no one can seem to get to work.
So what I want to know - Does any one actually have a working USB tether option? I more or less want to be able to hook my phone up start a download and walk away with out having to worry too much about the connection droping (like pdanet).
I find that charging via usb doesn't heat up the battery as much, and it lasts longer.
but this is relevant to my interests

This thread makes me really very thankful for my 40 dollar a month roadrunner high speed. 2 mbps and I don't have to worry about anything.
Ps I am not an employee of time warner cable nor am I receiving any compensation for this post
AT&T has great DSL, for low prices available in most areas.
P.S.:
DirecTV and AT&T are in no way business partners, and I do not get compensated if I convince you to sign up for their services...
Even though I'm supposed to...
****ing payroll.
I cant get anything except the "race" one to work. I have gotten it to work with every ROM ive tried as well. Usually takes a few tries and you eventually get the feel for the timing.
Very difficult to explain the timing . My internet went down one night and i did it desperately for god knows how long until i figured it out. I guess it takes a serious catastrophe like network outage for 10+ hours to make you desperate enough to fail, repeat, fail, repeat...
I figured out if you hit it to soon, it doesn't work, and if you hit it too late it doesn't work.

I don't get either of these services up where I live, and I absolutly refuse to deal with Comcast. USB Tether has always been my primary access point until WiFi tether which is just not near as helpful since my battery goes dead so quickly with it.
I got the race condition to catch one time last night in an hour and a half of trying, but when it did work my computer wouldn't actually show a network connection.
Just to make sure, when I turn on MNS it shows up as "HTC RNDIS Driver". Is that what everyone else is getting?

That's because USB charges at 500 mA, half of the wall charger's current.
When using WiFi tethering, USB charging cannot keep up with the current draw, and the battery will be completely dead in an hour or two. I've taken to plugging the phone in the wall charger, turning off the screen, removing the back cover, and placing the phone face down while doing WiFi tethering. This keeps the battery from overheating.
I can go all day with wifi tether via usb charging. I download a lot too

Really? I definitely can't. Lucky you
If I connect to wifi tether and let the torrents go, plugged into the wall I am lucky to get a little over an hour. Plugged in USB isn't a whole lot different if I start with a full battery. Just browsing the web I can go a few hours.

my computer has a metal case, and I use it as a heat sink.
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?

The only other froyo i've used was Kang o rama (85B) which doesnt heat up for me..as soon as i put in any froyo 91 in i get mad heat...I currently gonna test with applications as maybe its an app that is causing it somehow..I could be completely wrong but worth a try..But as I said i'm back to pauls froyo 50 and no heating issues

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!
