First of all let me apologise if this issue has been mentioned before. Just got my One last week.
I have noticed that when tethering as a Wifi Hotspot, while being plugged into the mains to keep charge, the battery temperature is being reported as around 51 degrees celsius by the app "Battery Monitor Widget", at which point the app notifies me that the battery health is no longer "good" but now "overheat".
I use tethering frequently and have been doing so without any issues on my Nexus 4 before I came to the One.
Should I be concerned by the temperature? Surely this will decrease the life of my battery/phone?
Many thanks in advance.
EDIT: I think this should be in the One Q&A, Help & Troubleshooting forum. Please move it if so.

The phone will get warm whilst charging and if it's working at the same time will get warmer.
When tethering leave it off charge and you should be ok.
Thanks for the quick response. Tethering seem to be pretty demanding on battery life though.
When tethering and charging at the same time the mA charge shows as 0 - as in the charge from the main is equalling the usage.
With the screen off and just tethering without being plugged in the drain is between -1400 and -1800 mA !!!! Battery goes flat in no time at all
Should it be that high bearing in mind that the screen isn't even on?
Thanks
I've read in another thread here on xda (I can't remember which) a response email from a tech representative regarding battery temperature. The guy said that as long as the battery temperature is below 55 degrees Celsius the battery will be just fine.

That's reassuring to know. It's just very worrying when you reach for your phone and it's like touching the sun :laugh: Keep checking to make sure my fingertips are still there or if they've been burnt off
I understand that the case acts like a massive heatsink due it's aluminum body. I use tethering as my primary internet source so I just hope keep at 50 degrees for most of the day doesn't reduce the product life too much
Just wanted to let you know that 50 degrees Celsius isn't something to be terribly concerned with when it comes to computer parts in general. Unusually hot? Yes. Technically, a hotter-running computer (or in this case, smartphone) is not as likely to live as long, but it's a negligible effect so long as it isn't 50+ degrees Celsius 24/7.
For reference, Intel's Sandy Bridge processor architecture is rated safe up to 83 degrees Celcius.
How about this? 65 degrees for a while!
Have a look at the middle of the screenshot.

An hour of temperatures above 55 degrees Celsius with a peak temperature of 65 degrees Celsius is very stressful in my book. I have Gsam Battery Monitor installed and I've set it to notify me every time the temperature goes above 55 (that happened only once to me for a few minutes). The cause why the phone's battery gets very hot is because I'm holding the phone in direct sunlight or/and I'm in a very hot environment or/and I'm doing some demanding tasks (play a game or/and browsing internet with 3G/4G on) . The solution to cooling it is to get out of the sun or/and the very hot environment or/and not to use it for a few minutes (because the aluminium case acts like a heatsink the phone cools very fast).

try this..
- switch off your phone..
- remove the battery for 3-5 minutes..
- insert the battery back..
- start charging but do not turn on your phone yet until it is fully charged..
below 40c its normal,
above 40c its slightly higher
above 45c its higher
above 50c its too much disconnect charger immediately do not useobile for some time
for going above 50c it will take too much time
Thanks for the help guyzz....
Oh u meant while charging, yes its perfectly normal, mine gets to 40 Celsius when charging. If u want it to cool faster, u may remove the back cover and switch off the phone while charging. And btw if u charge by usb, it tends to get less hot than with the ac charger.
What is the temperature on charging?? My Galaxy with Overclock 729 MHz arrive to 50 °C, sometimes arrive to 55 °C?? Your Galaxy arrive over the 55 °C??
funny my never geoes to 30c it stays normal like 25c while charging... is this a problem?? or normal
I work in a cell phone shop ( Technician Manager ) so i fix phones everyday. Most of the people on xda and the internet have noticed the nexus 4 getting warm, I myself thought so too. I did stress test's on Three devices 1.) Nexus 4, which was mine Rooted no stock rom. 2. Galaxy nexus, GT-I9250 rooted stock rom. 3.) Samsung Galaxy III, T999. Rooted running Cm 10.1 latest nightly. Out of the three I found that the nexus 4 had the lowest temperature overall.
. The Samsung Galaxy Nexus got 50-58 C, basic web browsing and watching a short clip on YouTube. 60-68 C Gaming. Game used Eternal Warriors
The Samsung Galaxy S III got almost the same temperatures as the Galaxy Nexus 45-50 C with basic web browsing and watching a short clip on YouTube. Gaming 50-60 C. Game used Eternal Warriors
The nexus 4 with basic web browsing got 35-48 C. Gaming it got 50-62 C
All of the Three Devices ran for 45 minutes and used the same Game/ video to watch.
Just Wanted to share this information, hit the thanks if I've helped you out in anyway
My Nexus 4 gets so toasty if im running Spotify & GPS nav at the same time on long road trips. (And its charging at the same time.)
Kinda surprised to see your results.
IMHO the glass on the back may feel more warm that the plastic back of most other phones because glass conducts heat better than plastic. That is possibly why this phone has the overheating perception in most peoples minds.

That's what came to my conclusion, for the glass that's on the nexus 4. Notice that I don't have it on the charge it's just on the battery. I think you will get higher temperatures when it's charging
The glass is good in a way or another. This way, it helps the phone's internal components cool down by conducting the produced heat outside.

Hi,
I agree... I had the 3 phones.
Maybe a thread that can help user about temperature or "pseudo" overheating...
When I see a thread like "My Nexus 4 is overheating, help me" it annoys me. No CPU / battery temperature indicating to see, just a "it feels hot, it overheats" or "I see some threads about Nexus 4 overheating, mine is also overheating, I read it " (it's real ).
Plus people confuse CPU / battery temperature...
Or people complain about "overheating" when playing a game or browsing while charging their phone...
Even 70°C for the CPU temperature is (almost for the the stressed people) nothing and there is a thermal protection in any case. Thermal throttling that reduces the CPU freq according to the CPU temp, same thing for the battery. And in case of extreme temperature -> shutdown.
I remember the max CPU temp for the Galaxy Nexus: 120°C before shutdown , it's not the same CPU but it can give an idea... The max for mine was about 90°C with some benchs, I see some people (simms22 if I remember right ) with something like about 110°C...
With my Nexus 4 (about 21°C room temperature):
Iddle temperature: 24 / 26°C for the CPU and 21°C for the battery
Light use after 15 / 20 mins (XDA app in 3g, homescreen setting): about 38 / 42°C (about 45°C with only XDA app) for the CPU and about 26 / 28 °C for the battery.
Hard use (browsing in 3g, Youtube, camera): about 55°C for the CPU and 31 / 32 °C for the battery (for this I don't remember exactly).
Extreme use (multiple benchs): about 72°C as far as I see for the CPU and about 38 / 40°C for the battery (maybe 42,**°C once).
Browsing while charging the battery is about 44°C and the CPU about 60°C +.
With _motley kernel, no undervolt, 486 Mhz / 1.51 Ghz, and CPU temp set to 70°C before thermal throttling.
I do agree that some people can have an overheating problem but not all the users / phones like we can read in different threads... and people that claims their phones overheats... when tey post the temperatures all is normal...
The feeling of warmth and real heat are two different things and it's very subjective to say "my phone is very hot".
Hi Viking37,
I feel fortable after reading your post.
I have been using Nexus 4 for a month on 4.2.2. and feel very bad on the heating and warm. (compared with previous Desire HD temperature)
I am based on Bateria App, showing only the Battery Temperature.
On Light use after 15 / 20 mins (Chrome or Dolphin browser on 3G): about 30 to 42°C on Battery, but i do not have CPU readings.
On Hard use after 30-45 mins (Youtube, Waze on 3G): about 30 to 42°C on Battery, but i do not have CPU readings.
I noticed i do not gets battery temp reading more than 42°C....
Hope you can advise what app you use to check the Battery and CPU temperature.
Thanks.
Hi ykit88,
You're welcome
For the CPU temperature I use System Tuner pro (on the Play Store and there is a free version), you can add a widget or download for free an "extension" to add the CPU temperature reading in the notification bar (you can set different update time).
There is also at least one more app (I mean that it works perfectly but I don't remember the name).
Your battery temp seems normal to me, it depends also of the room temperature and if you have a case (even if it does not have much influence).
@OP I don't know maybe is just because of Easter but I can't understand your first post, - is just too many Galaxies and I don't think there's Galaxy Nexus 4? But I may be as well wrong.
On the other hand phone getting hot is not an issue for me as HTC Desire used to get a lot hotter just with some browsing where you could smell a little bit of plastic

I'm still trying to figure out what is the reason behind not gaming while charging.
Temperature isn't a concern since this phone will throttle at the same temperature, regardless of charging or not. In one game, the phone will play to 42 degrees and keep it from going over. The phone reaches this temperature both plugged and unplugged. I do notice that the phone throttles more when plugged, but it successfully keeps the phone from getting any hotter than normal gaming temps.
So what is the reason not to game when plugged?

But on the charger you wouldn't be discharging, just a slower charge. With Dungeon Hunter 4, the phone will burn through the battery when unplugged, but it doesn't tax the system enough to discharge when plugged in.
I know previously, with my One X, super heavy games would cause it to slowly use up battery when plugged in. So I'm surprised I haven't seen that with the One. Maybe DH4 isn't as heavy as RR3.
But I'm starting to wonder if playing while plugged in is bad at all... consider laptops: If I wanted to play a game on my laptop, I would definitely have it plugged in. I don't think I've ever questioned whether that was bad or not. True, laptops have fans to keep it cool, but we already know the One will keep the battery below 43 degrees (at least for mine).

Laptops are made to withstand heat, and the way laptops stay on when on the charger is different. Most laptops use half battery and half charger power. When it's plugged in, you can yank the battery out and the laptop will stay on while phones run primarily on battery regardless if it's plugged in or not (THIS IS BASED SOLELY FROM MY OWN EXPERIENCE SO WILL PROBABLY BE HIGHLY INACCURATE)

That's how it will be, and it kinda proves my theory too. Phones run on battery even when they are plugged in, and charging it while it's also rapidly discharging leads to a very hot and very slow charge.

Also, I imagine laptops would be different as their power draw is so much greater than a phone. A laptop charger provides much more than ours, even tablets are this way. So then the question also extends to tablets: are you not supposed to game while plugged in on a tablet?
It would be nice if we had a technical answer to this from HTC or someone in the field. I hate having to constantly recharge my phone because I played a game on it for an hour... Especially this phone, it takes so damn long to charge!

I doubt it's as high as 65-70 Celsius - it would have shut itself down by that point. The hottest I've ever been is 45. Download a temperature app to see what it is. Turn your phone off or just let it cool down for a while in a cool place, then charge it again and see how it is then.

Lithium Ion Batterys DO NOT like to be charged at HIGH Temperatures
After doing a heavy intensive CPU App, or playing a game and the back of the phone is getting really hot, let your phone cool off before charging
I played Plants VS zombies for an hour and the battery temps gradually rose to around 68C which is 154.4F
Let it cool before charging, use a battery temp app such as "Battery" to monitor temps
I learned the hard way on my HTC One X after letting it overheat and then charging it while it was overheating it reduced the capacity of the battery ALOT and got the Red light while flashing when charging witch means the battery has overheated
Also
Your Phone does not have any active cooling system for the CPU, it has Passive cooling witch uses the environment's temperature to bring down the temperature of the internal cpu
Your PC has Active Cooling (Heatsink + Fan)
The nexus 5 has passive cooling (Heatsink only)
same goes with just casual wireless charging. be careful
A battery dwelling above 30°C (86°F) is considered elevated temperature

Odd, Is it really monitoring the battery temps? it seems to be linked to the CPU temp and the warm part is located on where the CPU is at and not the battery.

or if the charge falls too low lets say 2 volts it cannot charge again because it isn't a safe charging voltage
I think he was actually saying that the charging circuit wouldn't allow the battery to charge at high temperatures. I cannot verify that but since the charging circuit prevents over draw and over charge by cutting "power" it makes sense

It will cut off after reaching extremes. You don't want it reaching those extremes ever though or it WILL take it's toll on the battery.
Battery's don't like heat. They don't like extreme cold either.
Don't think the battery will ever get to 110F as the phone will shut down/not charge at that temperature until it goes down. Therefore, you probably couldn't spoil the battery if you tried with this fail safe implemented.
With someone's personal testimony about a fried phone, I can offer my testimony that I used a wireless charger on my Nexus 4 + played games until hot + charged whenever I wanted to and the phone, which my GF uses now, isn't any worse for wear.
Especially because the Nexus 5 has a Li-Po (lithium-polymer) and not a lithium-Ion battery

Hi
These batteries don't like heat full stop, they are like perishable foods and degrade quicker the warmer they are, regardless of being charged or not. This is why laptop batteries do not do well when the laptop is used mostly on the mains, nothing to do with constant top up charging, it is because the battery is constantly held in the warmth of the running laptop all day and age much quicker.
Lithium batteries do not work well in extreme cold, but this isn't permanent and they return to normal when back to room temperature, and lithium batteries are held refrigerated for storage, just like a perishable food.
Regardless of being used or not, the battery will lose a considerable amount of its capacity just by ageing over a year or two. Given the various safety controls built in, it is fairly difficult to cause much more damage than time alone will cause, so you might as well just use and abuse the battery anyway, especially as most people will be replacing the phone after a couple of years.
Regards
Phil

i dont think you know what the fail safe temperature is

there's a thread with someone's n5 getting to 45C(113F) while playing games and without shutting down, and he lives in Canada. imagine what temp it would be at in any reasonably warm climate
110F is not safe if you want to preserve the longevity of your battery. period.

Irrelevant as the phone has built in protections. If it is too hot it stops charging. FUD spreading.

Not irrelevant... Mine overheated while attached to my laptop and the led screen blew up. It developed a black bubble at the bottom near the home button.

No phones currently have no active cooling on them
Also heres what happened to my HTC One X
http://forums.androidcentral.com/ht...e-x-battery-draining-rapidly-overheating.html
It drained rapidly and the backside was always hot when it wasn't even in use just sitting on my desk caused it to got hot
and i would charge it to 100% and took it off the charger ~10 mins it dropped to 70% just sitting there idle and the back is super hot
my point is the charging circuit only controls for overcharge with is extremely dangerous

Just another example of Google cutting costs to put out this cheapo piece of %$))$!
But actually I did manage to really cook my phone! I set it (plugged in!) in a south-facing window to shoot time-lapse and oh-so-cleverly the sun bright winter sun was streaming through the thermal glass, and on to the silky black phone and...physics happened! About 15 minutes in my insta-greenhouse and I heard a strange whimpering 'ding!' from the phone -- when next I looked it had shut itself down. On reboot Dashclock was reporting "Overheat" "Not charging", and temp of 60+ degrees (can't remember the exact number but it might have been as high as 68!) Panic & a few minutes in the freezer brought it back to normal.
Take from that what you will:
1. It really dislikes being treated like a tomato seedling.
2. Idiot user didn't understand the 'greenhouse effect"
3. The phone does stop charging and goes into shutdown when things get too hot.
Before you judge too harshly, I want to point out the most obvious factor; a truly earth-shatteringly great phone would have come packed with the necessary technology to protect the phone in such cases -- maybe that would be a fan, or maybe it would be better served with a liquid cooling system, but whatever it should have, clearly Google cut corners yet again!

And the size and weight of the phone would grow enormously. Are you kidding? And what phone offered anywhere by anyone does what you suggest?

I'm not the smallest guy on the planet, but can you imagine the size of a the pair of cargo shorts/pants that would be needed to carry a liquid cooled smartphone? Massive!! lol
Fwiw, my N5 routinely gets to 107-111f when doing some intensive things with other background intensive things running as well (i.e. banning trolls on my phone both through Tapatalk and Dolphin while listening to a streaming content on mobile wireless and sitting in the sun soaking up some Vitamin D).
Oh ya!!

It ain't about the pants, it's about Google being too damn cheap to deliver truer-than-true state-of-the-state-of-the-art! Come to think of it, if Google had the balls to fill those pants we'd have the phone we really deserve!
68 Celsius is about 154 Fahrenheit. But as I said, because it was actually being cooked at the time.
