Liquid is too hot?

I mean really hot! Normal usage is ok but when I play games or use web browser for half an hour, it turns hot (back and front, lower body). Does anyone have the same problem?
Another thing is the charging time is too long!

Here are the answers from other forum:
Yes the liquid tends to warm up at the lower back half and once that happens, theres no way you can recharge it till it cools down. Feedback from acer engineers theres a temp sensor right behind the battery and if the temp goes above 40c...it'll stop charging. I think that maybe is one of the reason Acer didnt really launch this model worldwide?

Phones with Snapdragon chips in them get warm. The Desire does it; the Nexus does it. I wouldn't worry. My nexus takes about two hours to charger to full.

I have the same problem, its very hot, im worried for the health of cpu and battery..

At least for the charging troubles, using setcpu I defined to run at 500 (around) MHZ when on charge and no overheating then, plugged from evening till morning or using gps for 2,30 hrs with charge connected. It stills warm but no overheating... Tips from EvIl rom, not mine

The lower part is where the CPU is, battery heat would be from the upper back part. Also computer USB charging is slower than wall socket charging.

How does your phone heats up when running stability test cpu/gpu?

It would be nice to post your results here so i could compare them. Im suspecting that there is something wrong with mine from when it was returned from warranty repair.
That ****tards broke network reception when repairing power button, then led flash and gps. (Britex s.r.o., Kladno, Czech republic)
So here are mine

I think you dont know what you're talking about. You mean battery temp?
Obviously they didn't break your phone, what the hell are they gonna do to make your battery heat up, stab it with scissors? Short out cells?

Hey Mungulz,
I have trouble understanding you... sometimes you are very helpful, other times it seems you just want to bully people.
Maybe some anger management classes?
It doesn't seem that obvious to me that they didn't "break" the phone... damaged tracks (increased resistance) can lead to more heat due to a little something called Joule effect, I believe.
Also, afaik, our phone uses its case as a cooler. I don't know if it is supposed to have some thermal paste somewhere for thermal connectivity to the frame, but, if it is, openning it up for repair and forgetting to check/reapply paste can also lead to overheating.
So... for me it's not that obvious. Can you elaborate on why you think it's obvious?

I know what im talking about but that shows only battery temperature. just for reference. If its overheating its logical that battery temperature will be also higher because of heat cannot be diverted to the cooler parts of the phone.
I have disassebled the phone and the pcbs were badly alligned not to mention loosy heatsinks.
Sorry for my bad english.

Is it obvious for you now Mungulz that the repair shop might very well break a phone?
xtrustkillx, your english is great I don't understand what you are apologizing for!

@Lars: Or there are 2 persons using Mungulz' account.
@trustkill: be careful with those stability apps mate. I guess you already know that they increase the wear and tear on your CPU and GPU by subjecting it to threshold load right?
About the temperature, it's a difficult one to compare. I have my battery temperature at 1 to 2 degrees above room temperature when idle. (Therefore 33C from a 31C room.) But it goes as high as 42C if I charge it and not point a fan or AC to the phone. Thing is, I notice that my phone rarely goes above 41. I believe that our boards have an initial level of fail-safe where it lowers down the clock speed when the phone reaches 40C.

I just struggle to see how a poorly installed heatsink (assuming LG messed it up) can attribute to higher battery temperatures. in my mind this would increase CPU temperatures dramatically to the point of thermal shutdown, while the heatsink is not absobing as much heat as it should.
In theory the battery would be cooler if the heatsink wasn't functioning, as the CPU would shut down. I think this is just a case of far too much load on the phone. Really though if you put 7 watts into a phone this size it's going to get hot regardless of how good the heatsink is.
Furthermore, benchmarking while AC charging is always going to produce high battery temperatures, no matter if your phone was built on a Friday or Wednesday.
To me this thread just seemed like an opportunity to rant about LG or the repair centre, with no real goal.

@salisbury: I've seen in vadonka's thread (if I'm not mistaken) that you're right. It's actually something controlled by the kernel. There are three "charging modes". If the phone is cool, 1A (providing you're not in USB mode), after a certain temperature it switches to USB mode (that's 0.5A, either you're charging from an USB port or nor) and after a certain critical temperature it shuts off charging completely. These temperatures can be tweaked at kernel level.
@Mungulz: It seems you switched into your polite mode now. Much more pleasant and informative, thanks. I do not know how the phone is built, but, depending on how far the CPU is from the battery, are you saying it is impossible that having very high CPU temperatures will affect the battery's temp? I mean... in my head this is how I'm thinking... the phone uses its case as a heat sink (and there could be some very small heat sinks inside it), if these are not properly assembled, anything that is in contact with the CPU/GPU/whatever heat source will get hotter with it.
I can agree with you, if you really insist, that it is improbable that a battery in a poorly assembled phone will have temperature problems... but I don't think it's obvious! Even if it was there's no need to talk down on someone that suggested it as a possibility.

Well the heatsinks job is to divert temperatures away from the CPU.
If the heatsink wasn't installed properly, then the CPU would get extremely hot while the heatsink isn't getting as hot as it should be. Which would make the battery cooler than it normally would be. Just the phone would shut down within minutes

Note 3 Battery Temps? Is this high?

Hey all. So I have been monitoring my battery temps since getting the phone a week or so ago. (worth noting that Im on MJ5, with root, and have xposed + wanam installed). The temp while idle is usally around 70-75 deg. With some usage like surfing the net, etc, it is usually like 80-85 degrees. I believe this is all fairly normal. With that said, I also got a wireless receiver and a charger (TYLT), and while charging it shoots up to 90-98 degrees.
I do also have a Nokia charger which I plan to check shortly to see if different results. Also this is while in a case, going to see how much cooler naked.
Anyhow, can you tell me, is 98deg considered hot? Would this do damage to the battery or any other boards in the phone? I dont mean to over react but I dont recall my previous phone getting this hot so I wanted to check with the community.
Thanks all!

You failed to mention the most important thing, HOW are you monitoring battery temps?
How many amps are you charging at?
I may be an android noob, but I am a battery expert.
Might even call me a "know it all" when it comes to li-ion and li-poly

Sure the apps I use are GSam and Battery Monitor Widget
The receiver I got on amazon and is by the company fonesalesman. It has the added nfc piece in there
It charges on the tylt charge around 500mah
Also my phone is in a case from caseology if it matters
Thanks

Any battery when you charge is going to get hot. The faster you charge IE: the more amps your charger puts out, the hotter it will get. As long as it is not bulging or to the point it is uncomfortable to touch, it is fine. Even a little over 100F is still fine for a charging battery. If you top 115 then you are charging to fast as too many amps or your battery is bad. You should never use a charger that does more than 2.5 amps.

I would ignore them stupid apps and just go about your life.
There are only two ways for a battery to get hot, discharge faster than the "C" rating & charging with too many amps.
the N3 can't possibly draw too many amps, and charging at 1/2 an amp wont bother the battery either.
It is perfectly normal for any battery to get warmer than ambient temperatures while being used or charging, (that's how you know it's working),
and in your case everything is perfectly normal. :good:

Those numbers are totally normal.

Xiaomi MI5 temps while charging.

I can feel very hot the phone while is charging but i know at some level is normal for the quick charging, but i will like to know what parameters are normal or acceptable?
I try with a different charger (Xiaomi Redmi Note 3) and is gettin hot too.

My charging temperature is 43 degree Celsius using stock charger, I search on Google battery should be charged between 5-45 degree Celsius, so I think it's quite normal.
What's your charging temperature?

Around that too man. Thanks

I think it's not necessary to use quick charge provided by original charger most of times.
During night for example using a normal charger will warm and therefore damage much less the battery

Phone overheating issues

HAS ANYONE NOTICED OVERHEATING OF PHONE MOSTLY WHILE CHARGING, GAMING (should expect some heat not this much). I play PUBG on smooth basic plus extreme with no AA and gfx lower settings. Still phone heats up. FAN seems to be a marketing gimmick too. Circulation of air is v poor.
My question is can this be fixed via twrp custom rom tweaks. I'm willing to experiment.

Excuse me. Are you one of those geniuses who charges his phone while gaming?

I think nubia have fake temp status.
Or is that a bug i don't know
When i turn the fan on at max speed. Temp increased. Things like that happen. Or when i come back to auto from performance mode. Tem goes up.
Which is weird. Makes me believe that all this temp and gpu turbo and fan is a gimmick.
Air temp is 26 deg Celsius.

How do you measure the temperature? Was it a temperature of the CPU or the battery?
If your sentiment is not a user error or a fluke, then your unit is defective. Here's what one of the most prolific Youtube reviewers said about the fan - "it was keeping my phone 8 degrees cooler than my Samsung." I assume 8C, not Fahrenheit, because the reviewer is from UK.

YouTube ers are paid. I check the temp stats from gaming app . Inbuilt.
Plus the phone feels hot in hand. Not 8 degrees cooler. And Hunan hand can easily feel 8 degrees change in temp over 5-10 minutes

Instead of admitting that you were sold a defective unit and exchanging it for a working one, you think there's a conspiracy that involves the Nubia corporation and "paid youtubers."
But hey, I'm thinking this guy is not a psychopath. Maybe it's just a user erorr.
Maybe he thinks that having a fan in the phone should make the phone feel cool to touch during gaming.
Maybe he simply doesn't understand that the fan may be lowering the temperature from 55C to 47C, and that 47C will still feel hot to the hand.
Hey guy,
Can you actually provide real world numbers with screenshots?
No one has experienced anything like this before, so either your phone is defective or you have a nervous breakdown.

Yes, the phone overheats while charging but if you switch on the gaming mode to check heat also in certain Celsius comes down gradually and quickly in my case. So fans not a fake gimmick. Also when you are playing games heat is normal for heavy graphic 3d rendering titles like pubg, fortnight I play pubg with extreme HD and it heats but the fan keeps decreasing the heat. My suggestion is to charge where there is air free flow of air like a fan, AC, or cooler to keep ambient temp in control.

That is understandable, but then what is the fun of a fan gimmick when you need additional external air circulation with AC.
Even with clash of clans. Not much demanding game phone heats up. Plus additional charging while playing the temp increases continuously.
Circulation of heat and cooling inside the phone is poor. I'm starting to wonder if the battery has nay issues of heat while charging.

Low iq behavior? Projection much?
You are the one who's playing games while charging the phone, something that should not be done to a cellphone battery especially with 26C ambient air.
You realize that by charging and playing you are heating up the battery and the cpu at the same time and that's really going to cut battery's life real quick?

Apologies for the mess. Was relyed on Google voice without proof reading. I have edited now.

I'm not suggest to plug in a charger while gaming, it will make the phone hot, especially when you using the original fast charger. Anoher thing is you hae to know you can't get a high performance with the low temperature, if you get a very hot phone, the cpu will running in a low clock speed. The RM3 can get highest score on Antutu so I think the fan is doing something.

I agree the fan is going something. Had the circulation been a bit effective i think it could have been utilised in a more better way.
Anyways i was just charging the phone while gaming to test the heat limits. Not actually doing it.
Still i have noticed battery heat while standby charging
