Edit:
From what I have gathered from those that have provided info.
Around 120*F is normal for heavy use, around 105-110* for medium use, 100-105* for light use. This is with cell data enabled, wifi lowers temps 5-10*, also temps are for extended use scenarios. (over 10-15 min)
Heavy use= 3D game or graphically intensive 2D game, streaming videos especially HD
Medium use= basic games web surfing sites with lots of images or some flash content
Light use= sending SMS, basic fooling with settings or other basic functions, streaming music with the screen off
I think we need to get a bit more scientific about testing this overheating issue out. I need help from a large group of people. I need those who think they have overheat issues and those who do not for the info to be useful.
First off... I believe these temps are just the battery, not the CPU. I think the CPU is running relatively cool as the rest of the phone does not heat up, or it seems what heat is felt is coming from the battery only.
This would explain why people claim that the extended battery does not have this issue. As batteries with higher mAh ratings are able to handle the higher power demands with less heat.
We need to do comparison tests using the same apps across tests and the same use times as well. Also no over or under-clocking and using the same CPU governor. (and between everyone participating where possible)
I have Minecraft and Sleepy Jack, they both produce similar temps after 15 minutes of play time. (around 117-120*F) I do not know if it gets any hotter with longer use because I rarely play longer than that at a time. I am at about the same temp after only 10 minutes so maybe that is the highest it gets.
I know for certain that enabling WiFi has a big impact on the temps. My fiance's phone would only get about 95*F, (according to the SetCPU widget) but when LTE is enabled it would get to 115*F. Mine hits 105* on WiFi.
I want to do at least two tests.
Lets use the following steps to test:
-For all testing the test time will be 15 minutes of play time.
-Lets all use Minecraft since there is a free version and I know the app causes the phone to work hard.
-No over or under-clocking
-On Demand governor
Test 1) Airplane mode enabled
Test 2) 3G enabled (not everyone lives in a LTE area, if you do, data from LTE enabled would be useful as well)
Now some optional tests. I did some rudimentary testing and there seemed to be an impact on temps.
Optional 3) Using interactive governor or Lag free governor
Optional 4) Use a different kernel... If you are on stock switch to ziggy's and vice versa. (this may be the most promising test as since switching to ziggy's I have had a few lockups where the old Android logo pops up on the screen and I need to do a battery pull to fix it. This happens to the fiance's device as well)
If you do these tests, please post the results, and what ROM and kernel you are using. I will keep track of the results and update as appropriate.
Lets see if we can find some consistent data and narrow this heat issue down.
Edit:
Running Ziggy's kernel I hit 108*F kept playing and shortly after the phone did the odd crash I mentioned.
Nice, had the same idea to do one of these over the weekend - you just beat me to it
I've done alot of research/ testing heat wise, and the pseudo-scientific conclusion that i've come to is that in a room temperature environment something like 75-85F idle & 110-115F netflix is normal for this gen of phones (Rezound, Galaxy Nexus, Galaxy S II, etc) - Give or take another 5F if you're using 4G. Seems like some devices are luckier than others & stay slightly cooler, but i'd gauge that they aren't the typical use case. IMO, (along side battery) data is a huge reason we've seen some of the face melting temperatures people have been reporting.
One thing I think would really help this thread is to set an easy to follow format for posting results. For example, here's a few tests I've done:
### Phone Info ###
ROM - Stock
Kernal - Stock
CPU Speed - Default (1.5)
Battery Type - Standard
Case - Generic TPU
## Test 1 ##
Charging - No
Data - 4G (4 bars)

Hope this helps, i'd really like to see people participate - this information will be helpful for pretty much everyone in the Android community with a current gen phone.
Stock rom
Extended battery

3g, 3bars
This extended battery will get just as hot as the stock, just takes a little longer.
Edit-not quite as hot as the stock, but pretty toasty.
if it's the battery, then isn't the only parameter we need to test is current draw from the battery? no matter what radios/apps are enabled/disabled. It's bottom line is, the more we're drawing off the battery the hotter it's getting? I'd have to bring a pro in here on how Li-ion works in this form factor and why it gets hot, or what corners the battery manufacturer cut to make it possible!
The only time my battery gets hot is when I am in a weak signal area and the phone is searching for the 3G-4G signal. During daily use in a good signal area it never heats up.
My phone (and wife's also) heats up most notably during charging, especially when the battery is around 99% and going 100%. Usually the temp goes to ~ 45C (115F). In some rare cases, it was too hot to touch (dunno the exact temp). But some other times it would stay cool at all time.
Wife's first phone went into bootloop and her current phone is a new replacement. I kind of believe the overheating was the main cause of the bootloop problem.

It's more than just the battery. Also: feel free to post a test - the more data we get from everyone, the better.
One important variable missing: ambient temp.
I was just playing words with friends for ten minutes:
Ambient temp: 67, Screen brightness: 50%,
4g: ON
wifi: OFF
my temp went to 105F, it's NEVER gone to 105F when playing before... and I play it every evening. It was hooked to the USB charger at the time, and when I felt it getting so hot, I looked at battery monitor and my net charge was negative, so it was using more than it was charging off the usb...
maybe something in some of those apps triggers something that causes the temp to rise? a loop? something?

Good layout... and I think you are right about 115-120 degrees is normal for heavy use with apps that really stress the CPU or radio.

A pro huh... good thing I'm here.
Ok I'm not a "pro" as it were, but i know a thing or too.
Its not going to be simply the battery, but I think it is a big culprit, and most of these devices only provide battery temps, not CPU or internal temps, this limits our overall knowledge of what is going on internally. The battery getting hot causes the device to heat up as well so a bad battery that overheats can cause the device to overheat.
All batteries will convert some energy draw into heat. This is caused by the internal resistance of the battery. Li Ion batteries have fairly low internal resistance compared to other types, but battery design an affect power output handling. Pulling more power than the battery can handle or near its limit and you get more heat than normal. The heat to output ratio stops being proportional and becomes exponential. So that means the real kicker is the actual amp draw on the battery. How much power the battery can handle is related to both the capacity of the battery and the manufacturing process/ design of the battery construction. I bet the new devices are straining the battery more than the current design can handle. There are better battery manufacture processes for better power handling, but that increases the cost of the battery.
(BTW battery is a misnomer for these, they are cells, specifically one 3.7/8V Li Ion cell. The difference is that batteries are made up of 2 or more cells. This goes for AAA, AA, C and D cells as well. Car batteries for example are made of six 2V cells, 6V lantern batteries are made of four 1.5V cells and 9V batteries are six 1.5V cells)
This is one reason I want to do a test with airplane mode on. This helps lower the power draw and allows us to get a better overall device temp, this helps us know if there is an issue with the CPU getting excessively hot vs just the battery being stressed to hard.

I assumed most testing would be done at room temps of 68-72 degrees. If anyone tests in temps that are much higher or lower, then that would throw off the measurements.
I switched back to stock kernel, going to check for lockups and issues like I had before.

Charging always causes heat. You are forcing power into a small space.
Charging via USB should only get the battery a little warm to the touch. 95* or so at most.
Charging with AC should get it a few degrees higher. I would think over 100* is odd.
as you reach 100% is when the heat should spike to the max temps I mentioned, before that it should just be warmish.
I will check mine to see how it behaves, but all my R/C batteries behave that way.
Replacing the kernel with stock lowered my temps quite a bit. I was around 110-115 degrees after 30 minutes or so. This was with LTE enabled.
Nobody else have anything?
noticed most of my heating issues when 4g was on (even when idling on 4g). Leaving in wifi and 3g keep the stock battery cool...on the extended I never really notice the heat, even on 4g.
I realize that you're trying to keep things as similar as possible, but I had an issue today listening to the broncos game in the NFL app while charging. It got so hot it boot looped. After getting it back up and running I started monitoring battery temps and even with the screen off and just listening to the game, it would get extremely hot. Btw, I have 4G 4 bars. A couple of times I ran to the freezer and put the phone in it for a couple minutes to cool it down as the temps got above 117°F.
From here, I thought it might be the CPU, so I set the maximum setting to 384 in antutu and then let the phone sit there with the screen off just as before listening to the game and still charging. Same thing, phone got extremely hot, 115°F. Although, what I find strange, is I can watch Netflix while charging and even tho it gets warm, it never gets above 115°F and never goes into the boot loop issue. Same exact location, charger, ambient temps, signal, the works. So I'm wondering if an app is just poorly written and causes some sort of excessive use of the radio.
On another note, I had a rezound battery in my thunderbolt and never had any issues what so ever with heat.

What temperatures are you people expecting to see just out of curiousity? I mean if we run 3d intensive apps, videos, extreme web browsing we're going to see high temps since we are stressing the devices. We do have to remember these are compact devices and they are limited to what type of heatsinks/cooling they can add. From the multiple posts form this thread and others like it, we can see the majority of our devices run at same temps while under load. If it hasn't already been done maybe we should contact HTC and see what they say? Just a thought.

I am trying to find the norms and what is too hot.
I am thinking 115 is normal for heavy use. But we need to be sure, if someone says they only hit 100 under similar conditions as someone that hits 120. it may be that 120 is a problem temp and that 100 is normal. It may also be that the person only hitting 100 is just lucky.

Go play an app that is heavy in 3D, lets see what temps you get. If you go much over 120 it may be an issue.
Running Gun Bros for about 20 minutes gets me up to about 105°F. Right now after the phone had been sitting for 5ish hours doing nothing its at 98°F.

I think it is Ziggy's kernel I have never got 125f when tethering for 30min or playing GTA for 30 min. I am going to try another kernel.
I made this thread so that we can discuss about batteries and battery temperatures and how can we make our batteries more sustainable , i recently got my battery dead after 9 months of use so now im having a new battery. (My phone use is HARDCORE)
Recently ive noted that mobile is getting hot so i started to monitor my battery , im getting normal temperature in standby arround 30°C-33°C and when i normally use the phone it reaches upto 35°C-38°C but while playing games it starts getting above 40°C - sometimes 43/44°C and it feels hot too.
So i was just curious to know if there are people in xda who monitor their battery regularly. It would be good if everyone will post their battery temperatures so that everyone of us can have an idea of battery temperatures.
The app i use to monitor battery is "Battery Indicator Pro".
Thanks.
About the same on my infuse

But android phones means gaming to me, so i dont care about temp now ;D

Mine also goes upto 42°C
I have yuphoria on stock android. Its temp is 35c when idle , during normal usage 38-39c and while watching YouTube for 15-20 min it goes to 40-41c
It mostly depends on the device cooling mechanism.
Mine's Redmi Note 10. Unlike other phones, that come with at least copper heatsinks, mine literally got nothing but open aluminium sheets & a polycarbonate outer cover.
Stock MIUI temps are very bad. You can feel at your fingers radiating warm air.
After I unlocked & use a rom like lineage (without any bloat & heavy apps), temps really got down stable.
On hot summer, on standby, it usually sits at 32-33⁰c. On idle usage, it goes upto 38⁰c when I use social media. And 40-41⁰c when I watch YouTube at 720p. I think these are good numbers despite not having a cooling heatsink mechanism.
I go screen off at 100F.
If you're getting high temperature shutdowns you are at risk of damaging the device...
100% charge, high current drain, high temperatures, back to back high current drain/ charge cycles with no rest inbetween, discharging past 20%, charging with screen on... will take their tolls.
A battery should last at least a year and I'm a very heavy user. However if your SOT is higher than 14%@hour you are killing the battery. This type of Li doesn't like constant high current drain especially at temperatures above 102F.
Any battery swelling is a failure, replace it immediately.
Never charge below 72F, a minimum start temperature of 82F is better. Low temperature charging can cause Li plating which will permanently degrade the cell.
Hello, phones already, let's set clearly , very hot when you use it normally while charging (~45C° NOW in summer) then when playing , app report about 50C but it feels like much more... Those sorry of exploding galaxys are worrying me. What do you think?
Constantly running the phone @ high temperatures will probably shorten the life of the battery a bit, how much is hard to say. Does it shorten the life of the CPU or other components ? Maybe. But lets face it many (most ?) people change phones every year or two these days so that's not really an issue. You're more likely to notice the battery thing if you do it often enough.
Me personally, I don't do anything heavily CPU intensive with the phone while it's charging. I mean, how easy is it to do whatever it is you have to do with the phone (play a game or whatever), then throw it on charger when you're done & not using the phone ?
With the poor battery of the SII, I prefer avoiding such situation : playing with kill battery in 3h or less, so unless I'm closer to full charge, I'll play will charging. This to avoid ultra low battery at any time. I'm not concerned by battery dying, I'm concerned by the explosion as said...

As you said, high temperatures will shorten battery life.
An important aspect is that you shouldn't fully discharge the battery before charging it.
Charging from 50% to 100% will permit you about 1500 recharges.
Charging from 0% to 100% will permit you about 500 recharges.
I'm getting ready to pack in my M8, and I want to go the same size or smaller for under $450 (tops). The Z5c seems to be the only Android phone that really fits that bill while keeping respectable performance, but there are two issues that have me thinking twice: overheating and the "self-cracking glass".
I know nothing can be done about the screen (unless a tempered glass protector helps to keep it intact), but the overheating, if fixed, could sway me away from the Honor 8 or LG G5. I've read that the firmware update that came along with Marshmallow has largely fixed the problem, and combined with a patch available here that throttles the phone a little more aggressively, heat is no longer a big problem. That said, I'm concerned about gimping the performance of the phone in order to keep it from char-broiling my hands. How noticeable is the throttling and, if thermals are still an issue with the phone, how big of one are they?
If you wouldn't recommend the Z5c, the thermal issues remain or the throttling hurts performance in a noticeable way, I'd be curious if there are any other phones (with a micro SD slot) that you think are worth looking at.
Thanks!
Hey , i have my phone from March
this year, 3-4 updates still overheating..
battery top 46C, and cpu 60C MAX so far and stays there,
but! when battery reached 40C+ and CPU 60C+, device become 50% slow (i guess to prevent overheating)
on some games\apps you feel it, some not,
even on anutu cold device is about 90K hot device is about 50K score
after 5 -15 minutes of gaming already from 28 to 43, (depend room temp and game\app) sometimes i can shoot 4K videos for 10 minutes sometimes 1 hour
i think self cracked glass happening because two reasons
1 mainly reason: moving fast from cold when the glass is pretty hot by much (heat cause expanded)
2.sitting on device without notice
ps
sorry if my english is bad

Thank you! Do you know if the X Compact will run any cooler? The lower power chipset can only help, but I'm concerned about paying $500 for a phone that might not be as powerful as its older brother, which now retails for $100+ less, especially if the overheating and cracked glass issues aren't solved.
If only the Honor 8 wasn't riddled with iOS disease...
you're welcome
As far as iknow for the X compact does not have 4K, slower GPU,(CPU speed is about the same) not water resistant \proof
but he run abit cooler and got more RAM 3 for multitasking
i own only Z5 Compact
X compact base on youtube reviews and reading online

maybe hardware defective on some line, i remember every 3 months came new line ver 1 2 and 3 ( i think i have revision 1 or 2) 3 was available but didnt sold here
you can check your temp history somehow? like C3 widget?
or real time small app (shows cpu and batt temp)
maybe you dont play heavy games?
try run antutu 3-4 times see how much score is changing each run ,mine is from 90K to 50K more annoying then overheating himself

anyway , your antutu score is much higher than mine in the first time (i think depends what rom, kernel do you use..) , but like u see, mine didn`t drop at 50.000 in 3 attempts .anyway my max cpu temp was 42c when i run for first time antutu,

Any S810 device will overheat, it's inherently badly designed. Sony's hardware thermal solution is probably the best any OEM have done with the S810. It's also possible that Sony has optimized under-the-hood settings to further reduce load on the SoC and keep the temperature down.
Other software tweaks are mostly just a balance game of performance and throttling threshold.
Stock Sony firmware goes the more conservative route, so usually you won't experience noticeable heat when using it lightly.
It will still get pretty hot if you use it for intensive tasks that utilizes the full capacity of the hardware, such as playing demanding games, record in 4K for a long period of time, or watch videos that need a lot of complex decoding... etc.
If you're looking for performance without "unnecessary" throttling, just avoid all S810 devices.
Personally, most of the time I had no problems with the temp and perf of my Z5C, but there has been a few cases where I did experience slowdowns due to the throttling.
Got mine from December 2015. After few weeks of usage, it really overheats a lot. After several updates through the months, Device still overheats until now, still uncomfortable to the touch when it overheats. Tried reformatting yesterday, performance seems better with less bloatware stuff and on regular usage. But when cpu is under heavy load, device heats up and performance is reduced a lot to the point that it lags. But overall, still love my Z5C~ <3
It overheats uncomfortably. I tried xpower 4.0 ROM, smarttemperaturex mod, etc although it does reduce heat but not enough to be comfortable and im not talking about heavy tasks I'm talking about Firefox browser, WhatsApp and tapatalk.
The phone is almost never room temperature when using its either warm or hot which gets annoying after some time, don't even let me mention how hot it can get with few minutes of phone calls.

I'd say go for X Compact. Zero overheating issues. This heat actually gets on your nerves at one point. While the gpu of X Compact is inferior, in long periods of gaming there won't be any throttling on XC but Z5c will give half the performance so at the end of the day, the X Compact will feel a lot snappier

It overheats like crazy. I'm flashing 5.1 in hope that it will help.
When running Antutu i put my phone in refrigerator so that I can get a better score! :silly:
Any new cpu is hotter than quad-core of sd800/801 bcoz it's now much faster, even sd820 gets hot during heavy loading though better than sd810.
I've flashed SmartTemperatureX v1.61(no charging bug) and found temp is acceptable and battery life improved a bit.
Hello, I recently acquired the red magic 7 supernova, and I would like to know your experience regarding the battery issue, I obviously use it to play, and playing games such as genshin, 60 fps high graphics (not at its maximum) consumes almost 40% Battery in 30 min, that is ok? I do streams and I use only for games and daily use. I end up charging it about 3-4 times a day, would that be a problem or could something be wrong with my battery?
The smartphone consumes little both in Active and idle, this in normal use, during the game has high performance and three different power management settings, if you use balanced and 60hz it lasts you slightly longer. It is advisable to use charge separation to exploit it to its full potential for long gaming sessions.

You can always play on a charger with "charging separation " and you want lose battery
