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.
Reading up on battery life. Here is what I discovered. Its bad to have the phone running and charging at night, even though their is circuitry to stop it charging when it reaches a certain point. I do, however, need to charge my phone at night to maintain a full battery throughout the day. So why not turn the phone off at night and charge it. I tried it last night and the phone was cool to the touch when I took it off the charger(sometimes its warm when I unplug it). I don't know if that will preserve battery life, but I think this might be a reasonable compromise. Thoughts?
I've always just plugged in over night without powering down. My cell phone is my only phone. I never shut it off. If you are having problems with plugging in overnight then you should get your phone replaced. It's designed to be plugged in without a problem.
The problem with charging the phone when it is powered on, is if you have a faulty app or system process that uses too much cpu power, so the cpu gets hot, also the phone will be trying to use the battery while it is charging the battery, not a good thing, that`s heat upon heat.
I have see this happen a few times, went to pick up your phone and it was very hot.
I use batterybot to monitor my charge and battery temp levels and have a alarm set if the temp goes over 40c, also charge at 80% and discharge at 30% , I virtually never fully charge or discharge my battery as this can damage it and reduce it`s life by quite a bit.

Then that app would have caused an even bigger issue when it's actually in use, and anyone worrying about battery life who has not noticed what is eating his battery power during daytime really shouldn't be worrying at all
I leave phone for charging overnight on 2A charger, but it seems that after it's charged to 100%, current drain continues, since phone is still hot in the morning. If I leave it to be charged at midnight, it should be done in 3 hours max, so there is a lot of time to cool off. This does not seem normal and I did not have it with any other phones. I will try with motorola charger and report.

and its normal if you leave it in the charger all night, it will reach 100%, then drain a little, then charge it back, over and over. oh, and hot, what temperature? battery and CPU temperatures?

Bad signal. App/WiFi/radio scanning for connection.
Just switch the N6 one night in Airplane mode and check if the N6 is hot in the morning.
The problem is that this does not happen every time, but it's definitely not normal.
I leave my N6 plugged in ALL night, and when I unplug it in the morning, it is NOT hot..... So my only guess is that you have some apps running in the background. make sure the camera app isn't running, or any other apps. or better yet, put it in safe mode tonight, and see if you have the same problem tomorrow.
The only time my Nexus 6 is uncomfortably hot is after I play The Simpsons Tapped Out (this also drains, on average, about 20% of my battery within 30-45 minutes...) so I would echo that there may be an app running in the background that is causing the cpu to have issues. Have you checked for wakelocks with something like Better Battery Stats?
Can't figure this out for the life of me. I can wirelessly charge at any time except for if I'm using wireless android auto. Is this a temperature protection thing or is it a bug?
I have a damaged USB port so I'm stuck wireless for now. Samsung S21 Ultra
I think this has nothing to do with AA, but like you already guessed with a temperature problem. My P30 Pro is also getting really hot when wireless charging + AA and after some time I put it myself out of the charging station of my car and let it cool down, but it never stopped by itself till now
I don't know where you live...but with the hot temperatures we have now in Europe I also have the temperature issue.
I could charge my phone for only 2-3 minutes before reaching more than 40°C. At this temperature the charging current goes down and in fact I lose battery level in stead of gaining battery charge.
Therefore I'm trying now the ESR charger with cooling fan. ESR calls the cooling function Cryoboost.
With this charger I can now charge the phone for 10-15 minutes until it reaches 40°C.
Afterwards I have to let the phone cool down for 3-4 minutes and then I can put it back on the charger.
As I said, I'm currently testing the ESR charger.
So far it is a lot better with an active cooling fan, but not a perfect solution.
In the past days I also had some long trips. During 2 hour trips I charged the phone for 10-15 minutes, took it off and let it cool down and then put it back on the charger. With this strategy I gained in total 10% in 2 hours.
A lot better than before, but not perfect...
Long time experience with wireless AA and long trips (Galaxy S20). This is definitely a temp issue; after few hours of traveling wireless charging stops (with phone getting pretty warm) and battery drains. As this only happens after 5-8 hours of driving (depending outside temp? Use of android?) I put a wire to charge phone in the car and when it happens (only on long rides, more than 5-6 hours continue) I put the phone on the wired charger.
Solution with charger with cooling sounds interesting - I have never heard of it. Can You put link and your experience on the thread please? Thanks!
My experience is: it is a lot better than without cooling.
Nevertheless...as long as it is warm outside you have to cool the phone down in front of an AC ventilator of the car for 3 minutes after 15 minutes of charging. This is the case at around 26-28°C or higher or when the car was outside in the sun for long time. After driving around 20-30 minutes with the AC on, the car cools down enough to leave the phone on the charger for long time.
At temperatures of 33°C and more you really have to cool the phone down every 15 minutes during driving.
If the outside temperatures are high, but there is no sun, you can just leave the phone on the charger without worries.
At temperatures below 25°C it is also no problem to leave the phone on the charger.
Moreover I made tasker scripts:
- when the phone is put on the charger, it will tell me that it is charged and the current battery level
- when the charging is stopped, it will tell me that the charging is stopped and the current battery level
- as soon as I reach a battery temperature of 39.6°C, it will tell me that the phone battery is hot
- as soon as the battery temperature drops below 36°C, it will tell me that the battery temperature is normal
Therefore I have to say, yes it is better than without a cooling fan, but the temperature issue still exists. I could raise the outside temperature until when I can charge without worries.
So far I am happy with the solution as it is possible to gain battery level on long drives.
That's a nice solution (with tasker) - but as the battery status/charging also shows up as an icon on AA I just check the icon regularly during drivingn and when it stops charging put the phone on the wired charger. Works well on the long trips.
