Anyone else experiencing heat?

So, I've had my phone in my pocket for the last 30 minutes or so while listening to a podcast (not streamed, one that was downloaded) and I pulled the phone out and it was fairly warm. Nothing else going on with the phone besides the gmail sync, no downloads, no wifi, nada.
Anyone else seeing this as well, or do I potentially have a bad battery?

Mine gets a bit warm during charging, but not during usage i've experienced yet - but I haven't done heavy 4G data yet, only wifi and light 4G
Though to see it with no data usage is somewhat weirder.

I noticed with some heavy usage mine gets warm

um, your leg is typically warmer than your hand.
I notice my phones are usually warmer right out of my pocket.
or maybe i just have hot pants. BA DUM, CHING!

Mine gets warm as well with usage.

yes, when using my charger it heats up and after playing select games it heats up. Farm,city, and bakery story all make my phone heat up.
never when i'm not on the charger no matter if i am on wifi or 4g though.

I had the Zagg invisishield on mine melt and bubble last week while using GPS navigation for a few hours.

I noticed the exact same thing today. I had flashed das BAMF 3.0 RC2 the night before, followed by the newest dream kernel 2.2.2, and noticed battery was diminishing very quickly (could just be coincidence - not saying it had anything to do with ROM or kernel). Then I noticed the battery was getting very warm - something that has never happened to me, even with heavy duty use.
No idea what it was, but I ran out of battery pretty quick and just turned the phone off. Flashed imo's lean kernel when I got home to see if I could save battery.

I've definitely noticed when it's warm, the battery drains extremely fast. I'm surprised how hot it can get...using extended 2750 battery.

Thunderbolt definitely has a heat issue. My phone overheats when used in official ThunderBolt Window Mount for navigation. I have Tasker produce a voice alert when this happens. This makes ThunderBolt pretty much unusable for any long distance navigation, something my old Treo did well. It is probably combination of charging and rather mild San Francisco sun shining on the phone. Anyone from Texas had their phone explode yet?

What's odd is that when I'm on 4G at my office, and put my phone on the charger, there's no issue. When I'm on wifi at home and I charge my phone gets very warm; so bad in fact, that I get an inevitable reboot from overtemp. I'm having trouble diagnosing what could be causing this issue.
This is on a stock unrooted phone with MR2.

i was in Texas when my original droid got up to 170 degrees. i was sleeping with pandora playing, so it was probably that hot for several hours.. it bricked 3 seconds after unlocking it. no explosion or anything it just burned the **** out of my hand.
soooo happy i have the tbolt now!!!!!

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.

Bottom area gets warm/hot - everything else is great?!

This is odd but my Sensation is perfect from a hardware perspective right now (no guarantees on dust under screen in the future!) but for some reason the bottom area where the capacitive buttons are and the backside in the same area gets pretty warm/hot at times. Strangely no other area of the phone gets warm and the battery remains pretty cool. Also the phone doesn't exhibit any weird behavior or instability. I haven't had a single reboot or crash with this phone and I've been pushing it quite a bit.
So my conclusion is this heat is normal and how it's meant to be. Am I right?

I have the same occurrences with my phone. Great performance- I have YET to have it freeze/lag up bad or reboot.. and that is just amazing. Like I said in the other thread, the back of my phone will get warm, but never hot. I do think its normal, because it only happens after I have been using it constantly for 20+ minutes. (Still frightens me though)

I don't know about the bottom area but my screen gets pretty warm while charging and I am using it to play games or whatever but for normal use I never noticed anything else getting warm.

Just as a theory, the bottom there could be the location of the CPU.. I have yet to know or see a dissection of the device but i think maybe either CPU or memory is there.

CPU, cell radio, and charging/discharging circuitry is down there. The screen getting warm is just heat passing through from the before-mentioned stuff. Pretty typical from a beefy phone like ours. Good stuff!!

My phone gets noticeably warm too, especially when transferring a lot of data.

Mine gets warm when charging it at the same time I'm playing a game. My G2X is the same exact way. I really could give two ****s less how hot it gets. These processors were made to burn and if they burn up. Get a replacement.

Amen brother!

This happens to me too. It gets really hot when I'm charging it and doing something CPU-intensive.

all my touchscreen phones back to SPV's have got warm when in use for a while, so I wouldn't think this is an issue.

I think the reason why it gets warmer than other phones is due to the aluminum case. Aluminum is a great heat conductor, and the way I see it it's a good thing in this case. I'd rather have the heat spread to the outside of the phone, vs having all of those internal components burning up. With plastic shell phones, the heat builds up internally with nowhere to go. Hooray for heat.

If im charging and playing games for many hours, it gets a tad warm. A far cry from my other phones and unlike my iphone, the sensation does not lock up when. warm

I have same issue.I just buy sensation from tmobile store in full price and one day later I found when I am using phone for more than 10 mins the phone getting very very warm (hot) on the bottom of phone even more hot than hd 7
it is normal or not?? if not normal what can I do? can I call tmobile to exchange ?or htc ?

I think it's normal for our phone. and to be honest i'm sacred of using the phone for a long time either for gaming or web surfing it. well i just wonder would there be any water cooling solution for our phone like the one the pc. hahaha

Yes heat is normal. The CPU is in the bottom front of the phone. So that's where it gets hot. Heavy surfing and gaming will make for lots of heat.
For liquid cooling, place in ziplock and use under water

Extremely hot phone using GPS

Yesterday on my road trip, I was using the GPS. Had it on for like one hour, and towards at end when I went to turn it off, I noticed that it was really hot on the back , especially towards the button area. Also the screen was really hot. Is this normal? By the way, I don't know how to check CPU temp, but I got a program and it showed the battery temp at 40c/104f.

I'm interested in this topic, so ran a test on my Vibrant.
Went into Google Nav and set a route. Let the phone sit on a table for 1 hour. Screen stayed on the whole time. The charge dropped from 98% to 80%, and the battery temp ended up at 31C (87.8F).
Two factors may have made the results somewhat better than yours. First it was in my air-conditioned house the whole time, rather than on the dash of my car under the sun through the windshield. Also, the screen brightness was set to lowest, rather than max as it likely would be in the car.
Once I get my Sensation replacement I can run a similar test on it.

What did you use for the temp?
My phone gets very hot when using the GPS. This is on my 45 minute commute to/from work. It is almost too hot to hold.

Sorry to troll but I was outside today and my evo shift heated up to 139 degrees and I was only running my music player. No ill effects from the intense temp either... Shocked the hell outta me to see it get so hot though. My solution was to put shifty on an air conditioning vent, after 20 mins, back down to 90 degrees...

I used app Android System Info for battery temp.

Heat that high will shorten battery life.

Comparative and helpful 'trolling' is welcome!

I mentioned his in the Q&A forums but I average about a minute per battery % when using the GPS. At night in an air conditioned car my phone gets up to 39C with the GPS running. Yesterday I tried using it on the golf course like I have every other android phone I've ever own with Skydroid and the temp got up to 52C.

i'm getting another unit sent by t-mobile CS in a few days. i'm gonna extensively test it to see how it responds, i'll report back

Same thing occurred to my phone. I honestly have no idea if this is normal behavior as 3/4 phones had this heating issue either on the charger or off.

I am using my phone on GPS and my battery is getting very hot also. Just browsing the web is what I'm doing but should this happen when I'm not under direct sunlight or the phone on my car dashboard. Anyone else experiencing this and have a solution?

Newest version of Google Maps (ver 5.7) claims to have an update that improves battery power management during navigation.
Be aware that the Android Market app does not detect there's a new version. If you look at your apps Google Maps does not show a pending update, but if you select it the Update button shows up and it does the update.
Other good feature is the ability to download map segments for offline use in a 10 mi radius from any location.

[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.

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
