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.

Fried battery?

I was using a wifi tether on my phone running PCForce's CM7 and my phone restarted (it was connected to my PC via USB) and when it came back on it said "Charging 0%" and whenever I unplug it it switches off, never seen this before but it seems, to me, like the battery has been fried anyone think the same.
I also have a spare battery that works fine, which also tells me that it is some problem with the battery, and running a wifi tether can heat things up a bit which brought me to that conclusion.
Anyone wanna throw any ideas on if its possible to fix it, I am now using the battery that came with the phone but it has a crack near the contacts which doesn't fill me with confidence.

try with 600 mHz it solved the problem for me

With mobile data and Wifi tethering enabled, my phone can get up to 52 degrees celsius in some cases without charging. I usually turn the phone off and take out the battery for a few minutes for it to cool down. I guess a temperature that high is caused by overclocking. I'm not sure if its damaging or not but I do prevent progression of operations in that temperature.
I also have a crack on the battery. Had it for a few months now and no problems so far
How 'cracked' is it?

Its only about half a centemeter long, and it only seems to be affecting the case, but got a replacement last year (was the repacement that got fried)
Havent tried it with andreas's advice yet but I will

I don't think the crack will be that much of a problem. If you want, you could take it to someone experienced just to be sure.

It shouldnt, but I like to be sure lol.
Also setting to 600MHz didn't help, guess i'm stuck with my stock one for now.

wow, good job. Yep, mine charges up to 100% before the crack. After that battery hardly charges up to 97-98%.

I have crack to, but battery go to 100. Btw, i glue mine with tape.

my battery didnt passed 99% but i do wipe battey and solved the problem

well it's look like the rom's fault,change rom maybe work

My battery cracked as well, but it has been dropped a few times...
It is a real shame because my previous LG phone was the LG Viewty and that was an amazingly well built phone. Cost ~£100 and came with an amazing camera and 3G front facing camera too. Shame it didn't have android. So I don't know why LG decided to go really cheap on the build qualities - you'd think having cracked batteries would have come up in their design tests but they probably didn't care...

I got the same trouble...

PSA: Dont ruin your batterys!

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

I can't care less. It has 1 year warranty.

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.

it's to my understanding there are 2 sensors in the N5, one for battery and one for cpu

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

Explain my dead HTC One X battery? Exactly not everything works as it should be.
http://www.ti.com/lit/ml/slyp087/slyp087.pdf
if the temp gets high enough the chip cannot react fast enough
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
http://productforums.google.com/forum/#!topic/nexus/cVuWVDW-hyY
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.

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!

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.

[Q] X gets hot while charging? normal?

today is the 4th day with my Moto X...and i'm a little worried about my phone because of my battery issues.
the first day i got my phone, it came with 50% of charge and after some usage it got down to 14% but then, suddenly it dropped to 3%. I have some experience with this issue in my previous android phone, so i just tried a charge cycle and it is pretty much ok now.
BUT THEN
yesterday, my wifi was on and i was charging my phone and it went really hot, according to Antutu Benchmark the temperature was 45.1°C (113.18°F)... i quickly unplugged the phone, and it cooled down within 3 mins..
now today morning,
i made the phone shut down itself by draining its battery, kept on charge, i was not ussing it, only wifi was on and the temprature went 44°C (the charge was around 30-40%).. i left the phone as it is.. and then when the phone charged up to 92% it got better (37°C)
IS THIS ALL NORMAL? DO YOU GUYS FACE THIS?
if not, i'll have to replace this, so please help...
apart from this, i noticed that the device runs for a pretty long time at 1% charge

My phone definitely gets warm when charging. I don't have any apps to tell me the exact temperature, but it doesn't scare me. 45 °C is far below what the electronics can handle, and I wouldn't be concerned, it is well inside normal operating range in my opinion.

My battery is currently 102°f on network surfing the net unplugged. I've seen it as high as 113° and have not had any issues with the battery. I'm still getting 24+ hours between charges.

Batteries naturally degrade over time. That simply speeds up the process slightly (light tasks) or slightly more (gaming). I've done it on all my 7 smartphones (including my first from 2011) and all the stock OEM batteries are working to this day.
I've even gamed heavily (when I enjoyed those things..) on my S2 i9100 and iphone 4s and both those phones get awesome battery life to this day. The S2 was even left on a shelf in the garage over an entire winter lol.
It's just the word damages could misguide people so I wanted to clarify.
But charging temperature can vary between two identical smartphones. My first iphone 5 was rather cool to the touch while charging where as the warranty replacement I got (dust under the lens, they swapped it for a new one) I got tends to be warm and even slightly uncomfortable to hold while using the device moderately and charging at the same time (same charger). It's just variance in manufacturing. No two processors are alike, no two batteries are alike.

thanks for your reply everyone... i guess i'll have to live with it..
maybe i'll just avoid using my phone while charging..

fast charging issue?

hi guys, my problem is when i charge my phone on fast charging using original charging adapter it shows (fast charging for only 10-15m) after that it turns to cable charging and I'm still on Oreo no root, is that a hardware issue?
tried:
- cleaning the charging port
- factory reset
- flashing a new firmware
- tried another adapter and cable.
any suggestions? thank you

Maybe temps are to hot so it switches down to a less heating method for battery protection ...in the summer the fast recharging often doesn't work because temps are to high. To be sure, you can even try another cable (because adapters give rarely these problems but cables often get broken inside for bending them or the USBs plugs get worn for using it) when having the problem and if the result is the same, the reason is the one I explained. This thing happens even to other models so I don't think there's a software problem (as I know, never happened for this) so wipes are not necessary.

More the charge gets fast, more the battery gets hot especially if using the phone for something else while charging. In the summer, when the hoter outside temps gets the battery even more hot then it normally should be , to protect the battery (because it might even explode if to hot) in these cases software slows down charging. This happens for all models and even if it's true that cables often get broken slowing down chargings, a lot of people change unnecessarily there cables in these periods because don't know about the temp protection...
This is not a rule for the summer, but for everytime the battery gets hoter then an established temp so, it might happen even in winter if necessary .

Good thing doing this even for another reason : since having my phone, I used fast charge only a couple of times because I needed the extra speed for not having anough time to do the normal one. This because fast charge stresses the battery a lot so it's durability drammactly goes down if using it for every day charging and you will replace it sooner compared to using it after using only the normal charging for everyday usage . Sorry, but I don't agree... Don't think it's not good or worst than others because note 9's fast charge is coming out from the other previous models (S9, S8 ecc) and like for them, used when necessary is the best thing to do for having a long life battery and I'm also convinced that it's meant to be used when necessary.

If this problem occurred after update?
