N1 gets really warm when charging....................

well when i first got my phone i only charged it when the battery light was red and hollow. And at times i would put it under my pillow due to the alarm being so loud, didnt want to wake up my son.
But the past few days when i charge it and put it under my pillow it gets really warm, it never did this before, any reason why?

AFAIK all phones do, as well as any battery you charge (MP3 players, laptops, etc).

yea I agree, I think that is something most smartphones do, my mytouch did it... so did the g1

Thats because it charges at 1000mA via AC.
Don't charge it under your pillow! definitely not good for it.

Today I charged for an hour my n1 over usb.
It was really hot.
Then I go to home, and when I arrived, it was again really hot, and battery life is over.
So I reboot and now is ok, but is very very strange...

yeah they get hot, i have the battery life widget and also shows the battery temperature, when it was charging it peaked to 110 degrees lol

I came from a mytouch 3g, didnt have it long, i love Android, i guess i change the alert to something more calm. But before i charged it under my pillow and it never got hot. Maybe its a wear and tear thing

Any device to which you're pumping power into, or using power, generates heat. That's how it works. The only difference between the devices is how much it draws; the more it draws, the hotter it gets.

Yep. Don't charge under your pillow. It needs air or it will get super hot. Not a good thing.

Man...I thought my N1 was going to burst into flames today. 114.5 degrees...not sure if it would have gone any higher.
I was in the car using an AC/DC adapter. Had my navigation going along with my music. The glass on the phone got hot to the touch! I unplugged it right away.
How high of a temp can this phone endure without damage? If it were to overheat, would it just freeze up and shutdown?
Anyway...what's really weird is that the phone was plugged in when battery life was at 80...when before I unplugged...it was at 79. Huh?

warm nexus!
i charged my nexus tru the usb a few days ago, yes it got warm like always but when it was fully charged. it stayed warm even when it was unplugged from the usb. i know that was kinda odd and it drained the battery, it was at 76% just after 30mins. so i reboot and everything went back to normal. what the hell?! i think its a bug. what i do now just to be safe is i reboot the nexus after every charge and check if it stays warm...

Hot Battery

My phone is getting so hot while it charges that it is uncomfortable to hold. Are any other people having that problem? I'm afraid it's going to over heat to the point of no return.

Mine sits on the bed with me when I listen to Pandora at night. After a few hours I reach over to kill the tunes and it is hot. Not painfully hot but very concerning hot.

Yeah, when my phone was on the bed covered by my blanket, and my alarm was ringing for quite some time before I woke up, it was pretty hot. But it cooled down in no time.. so I wasn't worried. And it has happened twice only in my days of using the phone.

I can use mine for hours and hours and it doesn't get hot what so ever. Listening to music while browsing the internet and taking calls in between...

My Battery seems fine. I use setcpu with notifications if it goes above a temp. Never got one. and i check the temp now and again.
and it never feels hot at all compared to the vibrant.

So you guys think maybe I have a defective device? This morning it was was like my own personal hand heater.

I don't let my device get over 98 degrees farenheit. If its getting hot while you have it under the covers and listening to music for hours, you should consider not doing that anymore.

My phone has never been under covers while running. It heats up when I charge it which I can't stop doing because it needs power to survive. Also, it's spelled "Fahrenheit."

Right now when I put my phone to charge it gets extremely hot for some reason...I'm using the charger it came with and in just 10 minutes charging it gets to 112 degrees fahrenheit..i am running setcpu to the minimum when asleep and it still gets super hot for some reason..can anybody explain why it gets so hot?

My G2 gets hot when i charge and play angry birds at the same time... Sometimes it gets super hot when I charge from the USB port of my head unit (5V @ 500mA, I dunno if this affects anything).
It's pretty intermittent for me.
Also do you have a case on it? I have the black Tmobile gel case. I don't know if that acts as an insulator lol. I haven't checked temps

I had the same issue... I listen to Old time radio at night while falling asleep. Upon wake up one morning to an alarm on my phone stating my battery was over heating.... I ripped that sucker right the H3!! out and threw it in the garbage just in case it exploded.... scared me so bad that I went on amazon and bought a pillow speaker LOL

I think I may have fried my Incredible

I think I may have fried my Incredible last night. I was flashing or backing up my phone last night, I don't remember really, and fell asleep with it in CWM. I woke up some time later to find my phone in my bed in CWM and it was scorching hot. I took the battery cover off and took the battery out and went back to sleep.
About ten minutes ago when I woke up (yea I'm lazy lol) I tried to boot into CWM, nothing. I tried to turn it on normally, nothing. I plugged it into the charger and all I got was a blinking red light.
Anyone know if the battery is just fried or if the whole phone is fried? If it's just the battery I have an extra one at my other house about 90 minutes away (which I'll be going to in a few hours).

Hey I'm kind of a noob myself. Never had this problem, but which part was the hottest? You might be able to put in a new battery. Maybe you can order a new one like the extended battery

I don't remember, I had taken ambien lol I remember I had stretched out, felt it in my bed and it was hot, saw it was in CWM, then took the battery out and passed back out. IIRC the battery was pretty damn hot. I had this happen with my OG droid but it was only scorching hot for a few minutes and it was fine after, possibly because the case was aluminum and acted as a heatsink.

The red blinking light indicates that there is not enough battery power to boot up the phone. Leave it on the charger for about 20-60 minutes, and if it doesn't boot up then you may need a new battery-

Thanks, I'll give that a try.
Edit; that fixed it! Any idea why it would get so hot in cwm?

What all are you doing on CWM and how many hours. Brightness is also a factor.
I'm glad you saved your Incredible, though lol.

I'm not sure, like the user above pointed out it likely depended on what you were doing. If it was something that involved constant CPU usage then that would cause the battery to heat up since it'd be draining more power than if it were idle.
I really don't know the workings of CWM well enough to give you a good answer

Thats the odd thing, I wasn't doing anything it was sitting there idle while I was sleeping. I have no idea how many hours it was on (could have been 30 minutes or it could have been four hours).

Just a guess, it's probably because there's no power management going on, so everything's going 100% and loading down the battery.

CWM seems to drain batteries even while charging, and causes my phone to heat up a lot. I don't know the cause, only that it happens.

[Q] Charging phone and extreme heat

So I was charging my phone last night and it was under my pillow on airplane mode as usual, because I use it to track my sleep patterns. But this morning I woke up phone was off, with the charging battery icon showing only, and was so hot to the touch I literally couldn't even pick up the phone. I was really surprised it didn't melt or start a fire, that's how hot it was.
Now today after letting the phone cool down, it doesn't seem to be taking charge well at all, I'm having a very hard time getting past 25%, if I use the device while charging it will actually drop charge while in use (and this is with the wall charger).
I'm thinking the battery cells have been damaged by extreme heat. but just wondering if anybody else had the phone get this hot?

Sounds like damage to me! Sorry to hear that man.

Also seems like an irreversible damage to me :/
Some day I accidentaly left my LG GT540 letting it charge under my pillow. It got EXTREMELY hot and I unplugged it swiftly; I was so frightened that the battery (Li-Ion!) might have literally blown up.
To be honest, you should be grateful that your pillow didn't catch on fire together with your head, really... NEVER EVER LEAVE YOUR PHONE CHARGING UNDER ANY PILLOWS!

Well guys funny thing is, seems to be charging ok now.
I believe I'm having a similar problem that a lot of other people are having with the phone getting stuck on USB charging mode even with the wall adapter, so not accepting ACpower. But once I reconnected it a few times now its charing on AC and got back up towards 70%, so I think luckily I might be ok.
But damn this phone gets so much hotter than the galaxy nexus.

My phone never gets hot when charging...ever. I think you might have an issue with your phone

Moto X frozen

Welp had my phone for less than 24 hours and its basically dead. A little backstory, I had the phone down to 4% battery and decided to try the turbo charger out. I had it plugged in for about 20 minutes and came back to a pretty hot phone that was frozen. I unplugged it and it was at 50%. I plugged it into a normal charger and went to sleep. When I woke up the phone was off and still somewhat warm. Since then it turns on fine but freezes after being on for about 5 minutes. Any idea what is going on? I am pretty disappointed; but on the other hand sounds like I got the first lemon.

Looks like a faulty device, better return it and have a peace of mind.

Oh man, that sucks! I have noticed the phone gets extremely warm when charging ...
I guess you are going to have to get on the horn with Motorola support and see what they say. If they can't solve it hopefully they can get you a replacement rather quickly!
Keep us posted!
MOTO X PURE EDITION!

The heat concerns me on these phones. I've got an LG G2. I kept it on kitkat due to their lousy Lollipop upgrade that basically ruined my phone. It charges faster than any phone I've had, does not get hot and has the same size battery. I don't understand why the phone has to get so hot when charging. I hope they don't start having exploding batteries or other hardware failures like the OP is having.

Yeah I used my normal charger because I didn't trust keeping it plugged in over night. After about 10 restarts the phone started back up and was "optimizing apps". Now it's working but does get hot still. After a few talks with moto support I can confidentiality say they are worthless.

I definitely noticed the heat the first time I charged it. I pulled it off the charger this morning and it didn't feel warm at all. Not sure what the deal is.

I had a Nexus 6 for a while and any of these quick charge phones get warm when they are being charged. The quick chargers pump a lot more current into the battery than a standard charger. Electronics can take a lot of heat before they fail.

Has it frozen up on you again? I was going to recommend a factory reset, but I would definitely call Moto and see if they can get you a replacement sent out.
The phone will definitely get hot when charging at times. That's just a byproduct of charging, especially at 25 watts. Nothing to worry about too much, but it should have some smart circuitry that cuts off after a certain temperature or time is reached.

Mine did the same thing! Out of the box everything worked great - for like an hour. After that it's been non stop freezing up and the screen staying off with random vibrations.
I tried factory reset and going into recovery and wiping the cache. Nothing helped.
I had to call Motorola and they refunded my money and emailed a return label to ship it back. I'm going to have to order a new one.
