[Q] 4G on, getting hot - Epic 4G General

for some reason when testing out the phone with 4G on, it seems to get hot. At least hot so its uncomfortable in my pocket. Back to 3G and it goes back to normal temp. I usually get 2 or 3 bars of 4G where I'm at (Seattle downtown). This must be eating battery like crazy.
Is this what others are seeing?

does g1 get hot when charfing battery?

When I charge with adapter the bottom part is very hot so I can't hold it for long
I spoke to a t-mobile store rep, and it apears most g1s do this including the one the tech had to use as his guide.
Yup, mine gets hot as hell.
They all get hot when charging. In fact, mine gets pretty warm during extended use (web browsing, games, watching movies, etc)
it gets really bad if you've got EVERYTHING on and going at the sametime and your charging! almost burning!
I rarely do that, but it does get a bit toasty around the bottom.
I get hot when charging my battery! Ummmmmm.
If the battery gets HOT u better replace it, if its too hot for you to hold I think that is a hazard as it may catch something of fire! I can feel heat when I charge my phone, but nothing that would make me drop it like a hot potato.
Tell tmob to send you a new battery because you simply do not feel comfortable with the heat it's emitting....
is it the battery?
everyone asks if or says that their battery got warm/hot during use or charging.
I have noticed that the 'chin' area behind the trackball get warm to hot during use.
The battery, located in the middle of the phone doesn't itself get warm.
So, when you say that your battery gets hot, do you mean the chin area? or have you opened the back and felt the battery itself?
...........
in my experience all HTC devices do in the past ive had a HTC angel, Tytn, Tytn II, HTC Touch Pro all of which got hot whilst charging or extensive use nothing out of the normal with HTC devices if you ask me.
Mine got hot too..
But.. as i can remember.. The g1 was not having this issue in the past.. Are you experiencing this changing too ?

3G stability issue on Android phones?

Any CDMA Android users(Eris/Hero) here facing issue with 3G not working despite being in a good 3G area while other Sprint or VZW users having full bars while on your phone it keeps fluctuating between bars or 1X and 3G?
Very reliable for me... coverage in hawaii is excellent
I don't think its coverage, I think is more of a software thing from Googleing around
Yes, i've noticed this the past couple of days. In the same spot in my apartment ill have a strong 3G signal for most of the night, then randomly it will switch to 1x for a while, then sometimes after a phone reboot or toggling mobile internet i'll get 3G back.
I thought it was just a coverage thing but it wouldn't make sense to be, i have 5 bar signal.
Your signal is greatly affected by the weather outside. When it is cold or wet you have the chance of receiving a weaker signal. But when it is warm the signal will extend. This is because when it gets cold the particles in the air move around more causing the air to be denser. When it is warm this is the opposite causing your signal to flow freer through the atmosphere. Hope this makes sense I wrote it on my phone and didn't prof.
So, even thought is sunny outside and the weather isn't too cold(HB got very nice weather right now), the fact that I am sitting down in my living room and the data on my phone went idle as I am searching market place is due to the the weather? Odd....
http://www.the-cell-phone-advisor.com/cell-phone-reception.html Found this to help you understand and in reading it I got mixed up I think in my explanation. Sorry. Also, You don't have to sound condescending when you talk to people about things you don't know about. Or haven't researched.
Thank you. As a note the Eris was having problems with 3G idling and switching between 1X and 3G. An update came out last week to fix that, but some say that update didn't fix the issue.
You think I should exchange my Eris for another one and see if things are better? Or is that not worth the effort?
I don't think it is worth it. If it is only a firmware issue wait till 2.x comes and see if it is fixed. But I wouldn't give up the Eris for any of the other crap Verizon offers at $99 or less
Edit: Who is saying that it didn't help? I am really just curious to read what they have to say not mocking you. Link(s) please.
No I was saying return it for another Eris as I like the phone a lot. Well I am getting the feeling maybe the update VZW brought out didn't fully fix that issue that is all.
I am reading that this maybe an Android issue as my friend with a Omnia on VZW gets better speeds and more bars than I do in the same place.
The eris is imo the best handset verizon offers right now. The moto droid is a close second.
We should call and email HTC complain to them about this issue, so they can have it checked pronto. Please I ask you.
Isnt this just what Hybrid mode does?
So is this fluctuating 3G not normal? My real issue is the data connection being lost all together, which does essentially cause my 3G to come in and out.

I'd like to point out a fallacy in your post. What actually happens when something gets cold is the particles compact together, and when they get hot, the spread out. The exception to this is water, which expands when it freezes. This is why it's said you should run warm water over a cap you can't get off. Warm it up, expand the metal and there's more give.

Overheating problem

I'm wondering if anybody else's aria gets extremely hot like 45-50 degrees celcius when its NOT charging. It's not the battery that feels hot its the bottom of the back of the phone, with the case off its almost too hot to touch and the front of the phone where the buttons are. One thing I can't stand are phones that get too hot too touch when I'm using it. If it is just a defect in my phone i have a week and a half to take this phone back to the store and exchange for another one, just don't want to if i don't need to cuz Id have to unroot this one and root a new one. I know phones can overheat when they're charging but yeah it gets hot when its off the charger in the middle of the day.
Also my warranty sticker ripped the d off the word void because the battery was so hot it stuck to it.

mine has never been that hot if that helps, even after the first few nights that i spent rooting and messing with the phone
Mine gets warm if it's under heavy use, but I would never characterize it as 'hot'. Certainly not burn-my-hand hot.
If yours is too hot to touch, then I would say it sounds like a defect. Pain in the ass to have to re-root, but it's better than burning a whole in your jeans.
yea sounds like its defective... would def get a new one. Mine gets warm under heavy usage, but never hot.
i use my htc fuse all the time while at work. i use it to tether my laptop to it. when i download a large movie file which will take about 30-40 min the phone will heat up fast. and when i download back to back it stops charging the phone use the battery power. i think that the phone has some temp gauge or something to block the charge. don't care much for the phone if it goes bad. i have back up phones.
so to answer ur question. it will get hot if your using ur phone alot. and when it does it stops charging.
yeah i think i might just stick it out because i really do not want to have to re root it. i use it alot, but i hate how hot its been getting recently, i have until saturday the 18th so ill wait until friday and see how it is, it was fine today but if its still overheating then yeah ill take it back. I still have a warranty with HTC with the phone so if something happens after saturday ill send it back to them.
and yes, the HTC Aria has the overheating when charging mechanism to stop the charging process. which is nice. it lowers the voltage on the battery, stops the charging, and wont continue charging it until the temperature returns to normal. which most phones will just continue charging it even if its too hot. which sucks for people with those phones lol.
thanks for the input guys. if someone notices there phone getting "warm" if you can check the temp of the battery on your phone id reallly appreciate it. you can check it with spare parts or the battery widget(download from htc widgets) it will tell you the battery temperature. just so i can get an idea of what people consider warm.
My Aria actually got so hot while in use and charging that it turned itself off.
I was using Pandora, and Google Nav at the same time while charging that it twice that day, simply shut itself off. The whole phone was hot to the touch, so i now use a vent clip on holfer for it so its in front of the AC at all times while driving.
Glad to know I am not the only one.
I've noticed it also depends on the temperature of the enviornment your in.

Heat issues....
I usually have long conversations and this phone get really hot - even when not using speaker phone option. Last HTC I had (WinMo) got hot too. Anyone know if the Captiva get hot?
nope the captivate doesnt get hot. I mean if browsing the web/playing games on full brightness for an hour+ my captivate at most will get warm. but other then that it doesnt get hot at all.
Mine gets slightly warm after a good workout but if mine was too hot to touch it would have gone back for sure...no questions asked.
I have notices that mine does get warm depending on what I'm doing. I have also noticed that running either Pandora or Google navigation does seem to make the phone warm up. Maybe its the combination of the two apps running that is doing it.
By the way does anyone know if the cpu is located in the lower half of our phones where it is getting warm/hot at? And could it be that there just isn't enough heat dissipation is why we can feel it.
My only other question is are you using a case that covers the whole back of the phone? Are the results the same without the case?

Samsung Vibrant overheating issues?

Anyone else having an issue who might live in Texas? I notice severe delay in the OS. Also had a small 1 foot drop out of my hand while I was sitting down and it went CooCoo, had to reset, and reinsert SD card. Ambient Temp today was 97 55% humidity. I noticed my phone was actually hot in the heat, which worried me.
Humidity ? What was it temp wise? I have mine up yo 115 while charging ... it's a different processor it heats a little.. I returned one due to it but the new one is just as hot. Don't feel hott just says it is. No biggie. To me...

Been over a hundred here and 60-80% humidity, phone feels fine.
My phone has gotten got to the touch when pushed really hard and charging. I think its the battery... But this has been reported on other forums as happening often. If Tmobile says its the battery they swap it out for free. And if you aren't rooted they will swap the phone.

Its cool...
My phone gets really hot when charging
but also gets hot when doing a lot on it. Hot enough that you can cook an egg on it and I was uncomfortable putting it to my ear for a phone call.
My heat feels like its coming for the processor and not the battery.
I live in Florida and its always hot as hell an humid the phone hasn't had any weird issues. It does get hot while charging an during use at times.

I live in Texas and the temperature outside has been mostly in the 90's and low 100's during the day and in the 80's at night. I haven't noticed my phone getting unusually hot though. I does get a little warm while charging or during heavy use but no more so than my G1 did. In fact, it usually seems relatively cooler than my old G1 felt.

In tampa... handset does get warm to the touch, when pushing it through paces (GPS, 3g, heavy data use...), but not alarmingly so.
My phone hit 134.6 degrees this morning and its a brand new vibrant out the box just installed battery indicator to monitor.
I've had mine get really hot as well, up around where i'm guessing the processor is, not the battery. When this happens, my battery really drains. I've looked to see what tasks are running and could see nothing. Powering off and on didn't fix it. Taking out the battery did. It's happened just a couple times in the last couple of months.

Anyone else have overheating?

Seems like when,i use my phone between 20 30 min intervals it gets real hot in the back. I have a case and the whole case gets hot.
Today while listening to pandora for 45 mins while cutting my hair it just turned off. Phone was hot....
Anyone else with this issue??
Sent from my MB860 using XDA App
I don't have a case but I ran pandora for 2 and half hours today and the back was still cool to the touch.
I haven't had any issues with this. Used the sirius/xm app for about 2 hours and it wasn't even warm.
mine actually gets really hot as well. i used google navigation for about 30 minutes today and the back got really hot, mostly at the bottom half of the phone. i have a incipio feather case and the case got warm as well. i haven't had the overheating affect any performance issues though but am a little worried that it's getting so hot. are you going to bring yours in to have it looked at?

Same here, used navigation for about 20 minutes and the phone was very warm.
im not sure what to make of this. the first day i had the phone, i had a missed call, and the phone got pretty warm in my pocket.?!?!?! later, talking on the phone and it got to be almost HOT.
yesterday i had a couple of 20 minute browsing sessions and the phone just got good and warm. but it dosnt seem to effect permormance at all, and the battery isnt draining too fast or anything, so im not worried about mine at this point.
nope mine is always cool as a cucumber
Mine gets warm/gentle hot when browsing or doing any stuff that needs data transfer over 3G/H.
Have a movie going on (from SD) for ~2 hours now, and it is still cool.
Having come from the N1 where this was a constant issue I can tell you it is due to placement of parts. The CPU sits immediately behind the lower part of the phone. Heavy CPU use will result in a hot phone.
Also keeping it in your pocket will heat it up too. Body heat and background processes that use the CPU.
It is only and issue if you are very hot for a long time. Can result in reboots and crashing.
The back of mine did get rather warm in the car after using Nav for ~30 minutes, however this doesn't seem any different than what my old Tilt did and is normal for smart phones.
If your phone does actually get hot enough to power itself off, then I'm guessing either you've got it in a very poor case (or warm pocket with no ventilation), or it's defective.
Pandora alone shouldn't be enough to make the phone hot. I'd suggest try running it with the phone sitting on a table and no case. If it still gets hot after 20 minutes, exchange it. If it doesn't, get a new case.
I also have the feather incipio case. It got so hot it crashed.... Nice case but worried if it keeps getting hot it may, cause, life of phone to, be a lot shorter!!!
If it happens again I'm going to take it to ATT.

My Atrix that I exchanged today was getting warm alot also. Shoot the one I'm using now is warm. I figured the phone just has that problem. I have a friend who complain of theirs getting hot. Neither of us have experienced the shut down issue though. And I get it just from browsing the web!! I would have expected Motorola to discover this temperature problem during testing. They probably decided "it's not extreme, so we'll still sale a couple million." Heck Apple HAS BIGGER issues with signal problem & they are still selling like Red Lobster's biscuits.

Same here, the bottom of my phone gets warm from just browsing, which I'm not used to at all. However, it's good to know that I'm not the only one, although I wish none of us experienced this.
