Does the top half of your phone get hot with light usage?

I just noticed that after about 5-10 mins of just surfing the internet (wifi or 3g), the top half of my phone gets pretty warm. The source of the heat isn't from the screen, but from the actual innards of the phone in the half that's above the battery.
The phone isn't plugged in either.
I'm considering getting an exchange if others aren't having this issue.

Yes I've noticed the phone does get quite warm. It doesn't seem like there are any openings for heat to escape from inside and with as much power as this thing has it wouldn't have hurt to have some opening for air flow.

Not really. One thing I noticed is that my phone doesn't get hot even when playing games while plugged in.
On the other hand, my Nexus One would get REALLY hot when charging and using Navigation at the same time.

Not here either..

Mine gets a little warm during certain app usage. Not site which one causes it.
Its warm now and I was on Facebook, Firefox, xda and I have tune in radio streaming.

I had an N1 too. If I were to rate the N1's temperature as 100 points, my G2x gets to about 80 points on the same scale. But the only time my N1 would get that hot is if I was busy navigating GPS while charging. My G2x gets hot with me surfing in the shade, without charging.
So I guess I should exchange this sumbitch.

I don't get any noticeable heat on this phone, even when charging.

[Q] HTC Sensation 4G Battery and heat concerns

Hi All,
I got my Sensation 4G from T-Mobile US last week, and generally loving it. Beautiful form factor, great performance etc. However, I'm quite underwhelmed with both the battery life, and surprised and a little concerned with how hot the phone seems to get.
Regarding the battery, I've done a few full discharge-full recharge cycles, and what I find is that in idle, the battery seems very good. In fact it will stay at 100% for quite a while, but, when using it, the battery will visually decrease, losing charge every few minutes. This is with web browsing, twitter, facebook etc. The concerning thing is that when the battery goes down, it will frequently do a sharp 2-3% drop, instead of a 1% drop. I'm not sure if there are issues with the battery monitoring on this phone or not. If I leave the phone on idle, even for several hours, the battery will drop only a very few percent, which is great, but whilst using, half an hour or so will drop the battery by 10-15% or more. That's with the screen turned down to 25%, and sometimes 11%.
Does that more or less fit in line with everyone else's experiences?
About heat, on idle, the phone will generall maintain a temperature between 80-90F (26.6-32.2C) and feels almost completely cool. Same on charging, it barely noticeably warms up. However, when using, after maybe 10-15mins of web browsing, twitter etc, the phone will have reached temperatures of 105-110F or more (40.5-43.3C). The highest I saw it shoot to was 112F (44.4C). When at these temperatures, the phone is almost uncomfortable to hold. Not burning or dangerous, by any stretch of the imagination, but a little unpleasant. The heat is concentrated around the bottom of the phone - largely on the metal bottom back segment and base, but also the front of the screen - the capacitive buttons and the bottom of the screen.
I used it as a GPS navigator the other day for about 40 minutes in the car. Admittedly it was a sunny day, but by the end, the phone was displaying a temperature of 123F (50.5C) and showing an overheat warning. In addition, despite the fact I had it on a car charger, it had actually lost about 3% of battery.
To clarify, all the battery percentage and temperature readings I've quoted have come from the apps "batteryminder" and "battery life" - both with free versions on the marketplace.
I'm still within buyer's remorse period, so debating on whether to take it to the T-Mobile store and request a replacement unit, or, if this is normal and expected behaviour, then I have a decision to make about whether I want to keep this phone, or return it. Incidentally, I did take it to the T-Mobile store and got a replacement battery, to try that first, but it has so far made no difference.
So, I'd appreciate you folks' opinions and experience. Does what I've described seem like normal behaviour for this phone, or might I have a defective unit?
Thanks in advance for your help!

Do you have the screen on automatic brightness? Having the screen on for long periods at 100% will heat up the phone. Charging the battery and running CPU intensive tasks like navigation will obviously do that too. Add in some sunlight and this all adds up to a lot of heat in a very confined space.
Heat is a huge enemy of batteries and electronics. I'm not surprised you actually lost battery.
Moral: try to keep it cool.
Sent from my HTC Sensation 4G using XDA App

Hey, thanks for your reply! Generally, I keep the screen brightness down at 11% or 25%. Those are the times when, after some use, I'll see the temps of 105-110F
The time I used navigation, it was up at 100% (or else I wouldn't have seen it, in the sunlight). I had an HTC Thunderbolt which, when I used it for navigation, with screen up at 100%, would also get pretty hot, although it wouldnt lose battery whilst on the car charger.

Where do you live? Ambient temperature may have something to do with it. I live in San Diego and I've seen mine get to 44° inside the house.
50°C is too hot though. Keep it out of the sun and if it continues to get that hot get a replacement.

I'm in the Chicago suburbs and, yeah, it's been pretty hot and humid here recently. Also, my apartment doesnt have too great air conditioning - generally, when the phone is hot, I am too! I noticed the other day, at work, it was a noticeable few degrees cooler than it would get at home. Work has great AC. In addition, in the car, the day it got REALLY hot - it was an extremely hot day, and the car was like an oven anyway.
What you say certainly makes a lot of sense. I actually ran a test with the Thunderbolt last night, and found it would get up to 105F (40.5C) after a lot of browsing in the house. The sensation was maybe 5 or 6F higher than that - which is explainable by the dual-core and metal body. The metal body also being the reason the Sensation FEELS hotter.
Seems that the day-to-day general heat of the Sensation I experience may not be out of the ordinary. I am concerned about the overheating and battery loss when I used it for navigation though.

When i used my N1 for nav on its dock and charging for about 30 Mins (during fall, limited sun) the phone would get super hot as well. I checked the temp and it was around 47C. I have yet to test this on my sensation but i would imagine it being similar due to the similar materials.
In regards to battery temp on normal usage on the sensation I get as high as 38C while playing games, I haven't seen it go past 38C though. On idle it is about 26C, and ramps up to about 33C when I use the phone and not playing games. Compared to my Atrix which runs just as hot at 38C, being largely made of plastic, it actually FEELS hotter in the hand compared to the sensation, I don't think I will ever go back to a plastic phone due to this.

Mine gets to around 45C during Angrybirds play and the ambient temperature is around 25. I don't think this should be a problem since the battery is new and may be it gets hotter during the first few charges/discharges. Furthermore the aluminum body helps to disperse the heat better.

Thanks for the replies! I think its looking like my experiences are not a problem, and the heat is not out of the ordinary.
Regarding my GPS experience, I tested this evening whilst driving home from work (a 20 minute drive). I used navigation on both the thunderbolt and the sensation to guide me home, and put both phones on the dashboard, in bright sunshine. By the time I got home, the sensation was reading 132F overheat, and the thunderbolt not much lower - 125F, overheat. Sensation felt hotter in the hand (not hot enough to burn though) than the thunderbolt - due to the metal backing I'm sure. Thunderbolt felt pretty darn hot though!
The really interesting thing was, once I got inside the house, the sensation cooled down WAY faster than the thunderbolt. I think the comment above about the metal casing dissipating heat better was right on the money.
I'm more and more edging towards keeping the sensation!

ya camp i have the same phone as you and the battery ranges from about 8-14 hours with moderate use for me. if i'm using it a lot though i can get it to 0 in about 4-5 hours-before root anyway. so i believe yours is acting normal

Severe overheating?

Hey guys,
This last week has been absolutely brutal in the northeast us. We've had high 90s pretty much everyday. [Especially in the car] my g2x has been suffering from "random reboots" running fauxs 1.2.8 and kernel 0.3.2. It was a new phenomenon, I thought it was the DS kernel I had rather than CM7, but all that did was affect battery life.
I finally was using my device when it decided to "turn off" and the screen just kept turning off ( less and less time being on, fractions of seconds.) Then it just stays off and the battery temp reads 100+° at turn offs.
It requires a battery pull to turn back on ( and I guess turn off) but the heat doesn't seem to come from the battery, but behind the camera, im thinking processor.
Could it be from the OC/UV kernel. I had on? It's on standard now.
Sent from my LG-P999 using XDA App

OC'ing can easily overheat/fry the processor (hence why there's always large warnings around it), especially if the kernel hits a race condition or similar.

The phones are passively cooled. and the radios in the phone heat up the phone when used heavily. I have not had anyphone that didnt get extrememly hot while it is using the radio when its in above 80 degrees ambient temperature and overclocking would just add to this. luckily most have a feature ot turn off the phone at a certain temp to protect the hardware. But I dont think this is a specific g2x problme my old droid does the same thing.

I took mine to a pool in Vegas. It was probably about 90 degrees. I had it under my lounge chair shaded listening to music. It had a heat stroke after about an hour.

I understand why/how overheating can be caused by oc but honestly if its not running at stock (or benchmarking) I have it set to 800mhz by default- its still fast as hell. It hasn't overheated in the last few days, but the problem was that even if I don't use it, it'll overheat.
I use juice defender to keep my radio off when the screens off, so I can't even lay blame to that.
I haven't really dove into undervolting, but in theory wouldn't lower voltage equate to less residual heating?
Sent from my LG-P999 using XDA App

mine does this running stock. Mostly when I have the charger plugged in and am still doing something. It will be taking a charge but the batery level will still slowly fall, once it gets below a certain point it gets really hot behind the camera and the screen starts locking and unlocking. faster and faster until you finally have to pull the battery and let it cool down a while.

YES!!!! I have 2 G2x that do this, and a guy at work has one. All stock phones, and can be doing NOTHING - gets hot near the camera lens, and LOCKS!!!! Have to pull the battery. I pull the battery for 1 second, re-install, and G2x works fine. I know of 3 G2x, and all do this. I can't believe I don't see more of this on this forum. T-Mobile has a "discussion number" on this: 265747. LG claims ignorance. I'd love to know how to "fix" this. I'd also like to know if GB fixes this.
The occasional re-boots are live-able - this lock up is NOT.

I can verify this is an issue with my phone as well! It was happening all the damn time in both stock Froyo and EaglesBlood Froyo, but as soon as I went to CyanogenMod 7 RC1, I haven't had it happen once.
And to those of you who haven't had this happen, it's like the Sleep of Death + your phone gets REALLY hot by the camera lens and it keeps draining the battery and putting out TONS of heat until you do a battery pull. It brought my battery from 100% to 25% in like 30 minutes of doing this.
But CM7 seemed to solve the issue. No more SOD+heat!

This problem has been driving me absolutely insane. My wife and I both got g2x's at the dame time (new from tmobile), and hers rarely does this, while mine does it continually. I was wondering if it was related to the case we have - but we both have the same case - the speck one sold at tmobile.

My wife and I both have the little rubber buggy baby bumper condom case thing that does cover the back - that would reduce heat dissipation. I often carry mine in a belt case that came with the phone from CostCo - she almost never uses that case.

How warm do you guys let your phone get?

Hi everyone,
I'm about a week-long user of the M8 so far, and I'm loving it. I've been a fairly long time HTC user as well - I started with the Ozone, then fell back to a feature phone until I picked up the Incredible 2, which lasted for a long time.
At any rate, I'm no stranger to hot phones, literally. During my commute back and forth to work, I would use my Inc. 2 to record the drive with Dailyroads Voyager, while simultaneously monitoring road conditions with Waze. My good old Inc. 2 would power through those tasks like a boss, while at the same time burning up, and usually unable to pull enough power from the car USB charger. The only way to keep my phone stable was by running my car's defroster to blow cold air over the phone.
Now that I'm up to date hardware-wise, the M8 is no exception in the power house category. It can even keep charging while it's doing these things, although it does still get pretty warm. It's currently in a protective case which seems to dissipate the heat pretty well.
My question is, how warm do you guys let your M8 get? (Note: I'm rooted, but still running stock with no sort of overclocking involved.)

The only time I've ever had heat issues was when I mounted the phone to use as gps. And this was under direct 90 degree heat. Other than that, I've had no problems with heat whatsoever, even on prolonged lte usage and video watching.
My experience might be isolated though. I'd say, if your phone is uncomfortably hot to touch, you should probably ease up on it to be safe.

Yeah, always with the GPS navigation it seems. I wonder if this is something that can be fixed software wise (I.E filling a bug report to Waze/DRV), or if it's more on HTC's end for software/hardware...

I would assume it was just the metal body absorbing direct sunlight but I might be wrong. My HTC rezound used to double as a portable heater the way it used to get hot with extended usage. This one doesn't seem to be like that though.

Usually only heats when running tether for a period.

That's been my experience from the Inc 2, as well. So it seems like the mobile radio may generate quite a bit of heat...

I recently accidentally let my M8 get too hot while listening to music with it laying in direct sunlight face up. Didn't think about the black screen absorbing so much heat, got so hot it went into safety shut-off. It was almost too hot to touch, but after a couple minutes off it was relatively cool and turned back on fine with no problems or battery issue.

Low 40s Celsius is when I start to get uncomfortable. It's still safe, I just simply don't like it that warm. I get mad when my OC'd Intel cpu hits 60c even though 75+ is fine. I'm just anal about temps I guess

I agree that the only time (and it was only once) my unit got hot was while I was using it in its car mount and GPS was on. Otherwise I have seen none of the heart issues that plagued my Rezound and my Incredible.

I usually put it in preheated to 400 degrees and flip halfway through at 10 minutes.

If you're rooted, install XPosed and than install "CPU Temp in StatusBar" to keep really good track of the temps. Mine doesn't ever get over 110F, even under hard WiFi and streaming use. I've never used it for GPS in the car. At idle, it sits under 80F.

Thank you, I've been looking for a CoreTemp-like feature for my phone. I'll give this a try!

I've been hammering on my new m8 (swapping roms, installing massive amounts of apps, running tests, playing games ) for over a day and the phone has never gotten beyond lukewarm. Nothing close to what my m7 used to do

I never look at the temp. It will auto throttle if it gets too hot anyway. Just use the phone how you want and don't worry about it...

Well, I gave the temp monitoring thing a try (very cool!) and I don't think my phone ever passed 65 degrees Celsius, which I guess is ok. So no worries it seems!

That's a hundred and forty nine degrees F. Lol you need more ac.

Heat issues?

Has anyone experienced hot spots on their edge? there is a huge amount of heat coming off the upper right potion of my edge.

All Notes that I have had (1-3 and the Edge) would only get warm when running hard (nav + music) while charging at the same time. The Edge seems to do the same thing, but mine doesn't get warm at all under typical use.

I've had mine since Monday and it's barely gets warm whereas my GS3 would get hot. I haven't played many graphic intensive games yet, but have watched hrs of video continuously and the i think the only heat really is coming from me holding it. Other than that, it's been exploring the phone, surfing and other everyday use.

hows your battery life? mine is terrible and even though it's on a charger (not the fast charger) and shows that it is charging but, the %s keep dropping

My Note 3 got warm when I was online a lot of playing games. The note edge hasn't done this. Also I haven't play the game I normally b do.

How many days have it been?
I got mines on launch day the 14th. And it took a few days of draining it low and charing it back up before it started to last.
I remember when I first got it was it dripping to 50% really fast then start to go a bit slower from there.
But like today. I check a few emails and got on the Web and it went from 99% to 98% in 10 to 15mins vs day one where it would drop from 99% to 90 in 15mins.

Its actually pretty good. With moderate to heavy use, i get about 11 hrs but if i just let it sit with light use (checking email, light browsing etc) it drops slowly. It's at 4:45 mins now and I'm still art 91%. I wonder if your other charger is bad or an app is draining it. My nexus 7 (2013) drains on the charger if my daughter played her my little pony game. That app keeps draining in the background.

Specifically around the camera area on the back. This happens whenever I am downloading or updating software and similar activities which suggests to me it is a wifi issue (I dont have bluetooth enabled most of the time) Not sure if I should worry about this or not - the phone seems otherwise OK but does get hotter than my Note 3. In normal use, even while charging it is cool to the touch
