[Q] Any concerns about the heat the GT2 (7") produces? - Galaxy Tab 2 Q&A, Help & Troubleshooting

I've removed the back protective film and notice that just through normal browsing usage that the device tends to get a good bit warm. I also own a SGS2 which only gets warm during excessive gaming sessions.
Is there anything to worry about here or do I just need to get used to it? Due to the size of the device, it's easy to notice the temp change and it's always a concern. Is there an acceptable temp range and if so, how do you guys measure it?

Mine does the same thing. While browsing the Web the left side gets noticeably warmer. With that said the device never gets too warm. I checked it with a heat gun and the two sides(in portrait) Vary by about 5 degrees Fahrenheit(89 and 94) so it's definitely nothing to worry about.

My N5 comes nowhere near as hot as my N4, only slightly warm. And that is while playing Ingress and streaming music at the same time, something that would make my N4 choke

Mine's so f'n hot I can't stand it :good:
Warm across the top half and it seems I only need to have the screen active to cause it.
As I've said elsewhere, web browsing, email reading....nothing that should be stressful makes that top half of my phone notably warm (front and back)
Edit:
Just played Carmagedon, top half isn't getting any hotter but there's surely no way that web browsing should cause the same heat levels that a game does......

when i ran benchmark software(separate cpu and gpu apps), I only noticed the top half getting slightly warm. only on the back side
I noticed this afternoon that my phone was getting really hot in my pants. I pulled it out to check and it appears that the phone had shut off. I had to turn it back on, apparently something wonky happened.
Don't judge me....
I was playing Tiny Death Star for 2.5 hours (burnt %40 of my battery). I am extremely happy with that. I'm assuming I could easily get to 5hours screen on time. I did notice that the top half was getting warm (read:not hot). I came from using a HTC One X and it is definitely running a lot cooler than that phone.
Judging by the massive heat sink I have on my quad core processor in my computer (it weighs 500g), I think the phone is doing alright only get warm and not melting through your fingers.
Top portion heats a lot in my nexus 5. It all started after using fault 3.5 mm jack.
My n5 gets warm, but no where near as burning hot as my n4 did. But a lot of that has to do with plastic/glass. I've actually read that the snapdragon 800 on average runs hotter then the snapdragon of the n4. It's all about the materials.

Nexus 5 Heating
I have been using ma new N5 for the last one month and I realized that the device is getting heated up while browsing on 3G network and also playing HD games too.
Following are the few solution I am preferring:
1. Avoid stressing too much the Nexus 5 to prevent overheating injuries. Take a break sometimes.
2. Remove any casing whenever you are playing HD games(High Graphical) to let heat flows out.
3. It is recommended not play games while the phone is being charged unless your room is very cool.
Phones are getting silly thin and super power full = heat

Avoid using the Chrome browser as it tends to make the CPU run at high frequency and heat up the phone. Its a known issue for users but Google has done it deliberately to make the chrome run smooth.
Gets hot while playing certain games
i have tried a lot of games(asphalt 8, badland, dead trigger 2 etc) my phone generally has no major heating issues but two games plants vs zombies 2 and injustice really heats up the back of the nexus 5 to the point of unbearable. Also PvZ 2 drains the battery really quickly. Is anyone of you having the same issues? though anything else like videos or webbrowsing does not heat up the phone just makes it warm but such few games are causing lot of problems.
I can easily reach 100 F (or higher) just using dolphin browser. I haven't owned that many android phones, but that seems a little excessive. I would understand that temperature for a game, but not just for some web browsing...
It gets warm, but not hot like my Note 2 did.

[Q] Overheating Battery

I have two questions.
My Nexus' battery tends to overheat whenever I'm either playing games or charging. From what I've read, a hot battery will shorten the lifespan of the battery. What method do you use to cool down your battery?
This is a simple solution I came up with:
1. Take out an ice pack.
2. Envelop the ice pack with some sort of thin cloth (I used a microfiber cloth).
3. Take out the phone from its case and place the phone on the cloth.
I'm rather concerned about this method because it does cause condensation. However, the cloth applied over the ice pack is supposed to absorb the moisture emitted from the ice pack. Thoughts on this?
Hi,
First thing: can you provide the real temperature instead of saying "overheat" (it's like "it feels hot, warm, very hot, etc...")?
Second: are you sure you are speaking of battery temp and not CPU temp?
Phisically where your device is "overheating" (bottom, center, top right)?
what do you consider "overheat"? how it feels in hand isnt an accurate way to measure temp, as it could feel hot but still actually be cool. while charging, its normal and expected to get warmer. also while charging and using the device it can get significantly warmer. and the chances are that you will long get rid of your nexus before you see any real noticeable battery loss(2-3 years +).
Sure, sorry about that. I'll specify more in this post.
The heat is coming from where the battery is located and it feels very warm.
My phone went all the way up to 46C. (After cooling it off, it's 25C)
As for the CPU or battery temperature, the app I use only states "temperature: ". I'm assuming. it's battery temperature since the app monitors my battery statistics.

46C is normal for battery temp, especially while charging(its not that much higher than body temp, which is 37C). if getting up around 55-56C, then its getting a bit too warm. 60C is overheating for the battery(100C for the cpu).
Nothing to add much as what simms22 said, in any case there is a thermal protection (thermal throttling) and the last protection is a shutdown (for both about CPU and battery temp)...
We have a quadcore device enclosed without any "hardware" cooling system, so under some conditions you can expect some heat, nothing to worry about since there is a thermal protection.
You are on stock kernel? What is your room temperature?
To me your solution seems too extreme and useless ("an ice pack", all day, near you, ready to use it when you reach YOUR temp , stop using your phone in this case...) , search for "heat" in this forum, nothing wrong.
While charging I have something like 39/41 °C and if I use my phone it can go at about 44/45°C for the battery temp. For the CPU temp while charging it can go to 70°C (all browsing the web in Wi-Fi and in 4G it's more, 88°C but with custom kernel and custom thermal settings).
Honestly, your use phone like you want and like you need, don't bother, in any case if you have a real overheat you will know (see above)...

Does the device get hot?

Does it get hot under normal usage? How much degree celcius are you getting while doing basic task and watching video?
No no heat problems on mine. I believe Sony has introduced new technology for the heat problem.

Nope no signs of phone getting warmer. Played perfectly fine.
My XZ or XZs didn't get hot or even slightly warm, exactly the same deal with this, I would say it runs even cooler!

The phone is runs cool and somehow has what's turning out to be quite a long battery life

Well, I have been testing my XZP for two now. It is getting warm - definitely. If you put it under extreme load, it´s getting warm, even that warm your palms get a little sweaty - but not uncompfy warm. My LG G4 in comparison got that hot you´d barely wanna touch it.
Look for an app on Google play called "epic citadel" and run it.
Left it going for about 30 minutes and walked around a bit. Phone got Luke warm. Used 8% of the battery.
Not so much hot to me
Sent from my G8142 using Tapatalk
Any and all computer(s) CPU's will get warm to hot depending on the load. This is the nature of the beast. But mine does not get warm at all the way I use it. My battery life is phenomenal!
Gets warm if you play games for a long period, but nowhere near hot. Also I noticed that, compared to my old phone, the warmth is pretty much the same on the entire back. It's not just hot where the chipset is. All in all, the phone is awesome regarding heath control.
The phone does get hot after a while.
It's cool most of the time, and even if it gets hot, it has great cooling so leaving it alone cools it off in minutes.
As for the temperature, i was doing a stress test the other day (3D) and the phone seems to have capped at 38-39 Celsius degrees (that is slightly higher than body temperature so you can definitely feel it). I didn't check temperature after that though.
It also gets warmer while both watching and shooting at 4K, or high speed (even 1080p though).
However trust me, if you had the Z3 Compact like I did, that phone was a freaking furnace. My battery was affected by it. If want to use my Z3C as a gps in my car, i have to shove it in front of the AC to keep it cool otherwise I'm afraid it's going to evolve into a Samsung Galaxy Note 7.
So this phone is a big big improvement. Though I'd like a phone someday that definitely doesn't get hot. But maybe that's too much to ask.
As I'm typing this, after about 30 minutes of active use, my battery is 35 celsius degrees. From normal use.
A cell phone is just too small to dissipate heat in a very efficient manner. That is why super fast, and powerful, gaming desktop PC's have several fans installed in them along with huge heat sinks sitting right on top of the CPU. The heat sinks are larger than this entire phone! I am an IT Systems Engineer and if you've ever had the opportunity to go to a large data center where servers are housed you will quickly notice the high volume of moving air in the entire area. It can even get quite cold in some data centers all for the same reason... Computers can get very hot! So the fact that OEM's can keep these things as cool as they do, with the CPU housed in such a small, airtight space, is really a marvel of engineering.
Hello , the phone doesn't get hot like my z2 is used to be , I've managed twice to get the phone (on purpose) , but with normal usage 4K video / gaming etc it won't get hot unless you spam many task at hight speed

HTC u11 heating

I just bought the HTC U11 and it's amazing. The only issue is that since I turned it on it feels quite warm in the hands. (I'm not used to that unless it is on heavy usage)
Is this normal? What are the normal temperature ranges? What are the temperature ranges that you are getting when you use it?
My phone seems to be at 36-40 degrees when connected to the internet, not downloading any apps and on light use.
What's the highest temperature at which I should start worrying?
For 20 days I have it, I have yet to experience it warm in hands (no matter what I do). This is current situation:
Maybe it's doing some updates in the background? Like for me, the Google photos in the beginning (of setting up the phone) would be downloading the thumbnails from my account. My phone run pretty cool to touch, even when running Candy Crush... on my Moto X pure it was hot when doing that.
35-40 degrees is standard for me under normal use, with HTC's bundled case and 28ºC room temperature..
The phone only gets a bit warm (not burning hot at all) but I'm worried about the long term effect on battery life.

Thanks! This sounds similar to what I'm experiencing. What's weird is that whenever I use the phone I also get a tingly numb sensation in my hands and arm (which has never happened with any other phone)which is also making me more sensitive to it.

It's still the same case even a day later, so I don't think it's because of any background updates.

Are you used to smaller phones? Phablets like this are a bit awkward to handle unless you have huge hands, maybe that's the reason.
Mine heats up as well. I only play games like Angry Birds, Plants vs Zombies and Candy crush. I installed CPU-Z to monitor the temperature. Cpu temperature is around 45-47c whole playing games. It reaches 50c while video recording. While Browsing and reading, the temp is around 38-40c. The area above the fingerprint sensor gets warm first and then the rear (near the camera). Is this normal?
50c is nothing unusual for a htc device. If the device feels warm to touch then everything is normal. If the device feels ice cold and you record those temperatures then you have a problem. The chip will have a thermal cut out switch so if your phone gets too hot it'll switch off. I think it's somewhere around 60c-65c as 70c is the standing temp for boiled water which can cause serious burns to skin, like a cup of coffee or tea.

Question about heat issue and screen dim

hey guys !
iv got real issue with the flip 4 , i like the brightness to be full and also the extra brightness
but every min that i just do simple stuff like open face book or just playing few sec with the phone my phone begin to warm in the upper side
and the screen dim much , but i only do stuff like few second so whats the point of the brightness
im at home and its not hot in my room.
maybe its defect of the screen or its like that ? cause when i hade s 22 ultra it also dim screen when get warm and the iphone also dim the screen when become hot but in the flip 4 i just do simple stuff and the screen dim then even the brigthness slider when i play with it is not function wtf? can you help me thx
Why are you burning up your retinas? Dim light isn't harmful to your eyes but bright light can be.
There absolutely no reason to use full brightness indoors all the time.
Moreover full brightness greatly reduces battery run time, lifespan as well as display lifespan.
It's best practice to not use these devices in direct sunlight... it will rag them out.
If you're hitting the thermal limits of the device and its battery or cpu core temps are too high ie the device is operating within normal parameters as opposed to a defective thermal sensor all you can do is reduce the load.
By turning down display brightness, reducing bandwidth usage and better optimizing the device to reduce power consumption. What's it's average mAh usage? SOT?
Heat is the inevitable byproduct of power consumption; reduce power consumption to reduce the heat.

Is it just those 2 social media apps doing this?
I don't allow any social media or shopping apps on my phones. Trashware at best, spyware and/or malware at worst.
Just general use outside/car mine gets pretty warm and screen dims. Compared to my S22 Ultra it rarely dimmed but also a bigger phone
You likely know this but it bears repeating:
The processor and other circuits are mostly on the upper-half of the phone, near the camera. These chips do get warm, even hot, when applications are in use.
A lithium ion batter, when being charged or discharged, gets warm, even hot, depending the current flow needed to operate the applications, chips, and screen.
An OLED display can get warm, even hot, when lit brightly.
An OLED screen in sunlight will get warm, even hot, even if powered off, because it appears black.
Outside, if the OLED is bright white, it still gets hot because turning on all the pixels takes power, which is expressed as photos (light) and heat.
A very compact phone, like the Flip, has little surface area to expel heat. It doesn't have a fan, so the only way the phone cools is by convection (passing heat to the surrounding air) or transferring heat to your hand or (don't try this) water.
A folded Flip has about one-half the area to dispel heat because the screen cannot effectively radiate heat to the air or your hand.
Some applications use a lot of processing power even if you think you're using them. This is why so many people on this site discuss removing and/or disabling applications.
You can check in Settings --> Battery and Device Care --> tap on Battery --> tap on the graph, and the phone will display which applications are using the batter.
It's my understanding that the processor, battery and screen all have "checks" to ensure they don't get too hot, and Android can throttle these components to prevent wearing them out, burning them out, or causing a fire.
Hopefully others will better understand some of the challenges Samsung has in creating such a unique phone.

My flip4 is up and running and no negatives so far. Just slightly warm while I was downloading over wi-fi some 15GB of my music. The overall quality of this phone is pretty good, just like my S22, but it folds to 1/2 of S22 in size. Spent several hrs setting it up and debloating, I always do these things manually. This phone is very responsive and operates smoothly.
On the side note: picking up the delivery from Bestbuy, rather than getting it to my door by Fedex, wasn't a good idea - now I have to look somewhere for an mt box for packing up and shipping my trade-in, Bestbuy just handed to me two small retail packages w/ the phone and silicone cover. They don't handle trade ins.
