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!
Hello everybody,
i wonder if any of you encountered the problem of not charging the battery in the car while using TomTom 6. It happened to me many times and it's quite annoying because at a certain point the phone will go off and it will need to be charged while off otherwise it will not work.
Since it happened in different cars it does not depend by the charger but has to be a software problem either of WM or TomTom.
Any suggestion?
Thanks!
Panco
Buy a decent charger with at least 2A.
2A? 1A should be more than enough...
(I'm not sure you'd be able to find a 2A USB charger as the USB2.0 spec requires connectors to be rated at 1.5A tops so if there was such a beast I personally wouldn't touch it)
Mathew
Do a careful inspection of the USB connector on the phone and the car cradles/leads - my money is on a piece of cloth/fluff etc breaking the charger connection.
Today, I tried using CoPilot (with a live internet connection going for Traffic updates), with bluetooth switched on (so that I could connect with my Parrot kit in the car), and the phone on charge.
On the journey back home, CoPilot was running (and on the screen) whilst I was on a call via the Parrot. And yet, the battery was still getting charged properly! I was actually impressed that the charging would work automatically once the cable was inserted - my MDA Pro needed the display to be off before I could see the red charging light come on and for the phone to start charging.
FYI, the charger was a cigar_lighter_adapter-2-USB_cable type.
I've got an MDA Compact IV with the original ROM (but TouchFlo tweaks, etc).
So, I'd say either there's something wrong with your adapter, cable, or indeed TomTom is using a lot of juice!

No, it does this with most GPS SW and the problem is heating preventing battery charging to avoid the battery to catch fire, especially with the the phone placed in the windscreen with the sun on it. At night the issue is no longer an issue. So when you have a break for coffee let the phone have a break too to cool down and recharge.
Or mount it infront of an air con vent

Thank for your post, i think you got the point with something (the heating of the battery+gps) preventing the battery to recharge; i'm convinced of this because the problem is not always present but it comes at certain conditions.
I'll try to let the diamond cool down at regular intervals and not to position too exposed. I also noticed that it's advisable to first connect the phone to the charger then after some minutes run the tomtom otherwise the problem is likely to happen.
Thanks to all.
Panco
There are many tool available to show you the internal temperature of the device - the battery monitor 'Batti' is one such tool (and it's free).
Give something like that a try then you'll be able to see if your problems bear any correlation with temperature.
Mathew
Im experiencing the same with Garmin, yes, it was hot...first I thought the cigarette-to-usb-adapter was not strong enough....
Will try to keep it cool
You need a USB car charger with at least 1A, as said in previous post, but with any USB cable the current limiting will be lways be 500mA.
Only the original Diamond cable will allow you to charge with currents over 500mA. To measure the charge current you can use several programs, like my TodayWarrior (as it is a plugin you will need to disable temporarilt Touch Flo or use Second Today).
It's not heating of battery, but just that when Using tomtom, with backlight, Full GPS usage, phone on and that VGA screen just pulls more than your charger can bring
Got the same issue, and yes, as said before, get a heavier charger.
I have the same problem using IGO8.
First point, using Full GPS in car will consumme a lot of energy.
So it's better to use a 2A/5V charger (5V is the important thing ... And for your information, HTC is selling 2A car charger for their last phones ...)
Second point, the GPS chip is badly placed in the phone, behind the battery.
So yes, when the GPS is used for a long time, it makes the battery hot and the phone stops the battery charging ...
The point is to use a good car craddle, one that lets the phone "breath" (one that doesn't cover to much the rear of the phone) ...

The input sideon car chargers inclusive of HTC is 500 mA at 12 V and the output side 1A at 5V, which is what the phone requires and all car chargers I have do. But the important thing about ion-lit batteries is that they require very controlled charging conditions (contrary to the older Metal or Cadnium). E.g. If the battery is completely flat (2 V or below) it is extremely hard to recharge and will require several hours in the charger while building up the voltage to about 3.2V, only then normal charge will start. Sometimes the stand-by consumption of a phone makes it imposible to recharge it while in the phone, and requires an external recharger. This may explain the observatiobn that it is better to wait a couple of minutes before starting TT after connecting to the recharger to ensure correct initial charging.

This is the way to get a battery to explode, but fortunately the phone will not allow charging to take place and adding more amps will possibly increase heating and just worsen the situation. But correct as more power the device draws as hotter it gets and as sooner charging stops.
As Nani says there is an element of disign problem (cannot be a surprice to HTC that people actually will like to use the Navigation also on long drives), so if placed so it can cool will defenetly help. So will dimming the display to the minimum.
There are times when my HTC Touch Diamond refuses to charge on the battery even though it is plugged in. Other times, like when I just get off a hike where the phone is at around 5-10% charged and I get into my car and plug it in and continue to listen to say a a streaming podcast, thus the phone, bluetooth and data connections are being used and the phone is drained to 0% where it shuts down. All this while plugged in! Can't the HTC Touch Diamond run and not drain out as long as it is plugged in???
When you plug a charger the phone's battery starts increasing the temperature. When you use the bluetooth, GPS, WiFi etc. it heats the processor and the phone becomes more warm. When the phone exceed a determined temperature it stops charging to preserve destroying of the battery and the phone. When the phone stops charging it begin consuming the power from the battery.
P.S. I hope I explain it well and you managed to understand me. If you couldn't understand Sorry for my English!
So then you're saying when this happens I should submerge my phone in ice water?

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.
