well...when we all talk about limitations and issues of android build the first thing we always say is "battery life", but what concerns me more is the overheating.
i know the 2 issues are related to each other, but i don't care about battery life as much as the device temperature, because it might damage the internal hardware right? plus nobody likes to hold a piece of burning plastic in their hand
Does yours always get hot? Mine got hot during the first run of Android(all that loading crap). I got a little worried to I let the phone cool while off. Been running it for hours now and it feels exactly as it does in Windows. And battery life is pretty awesome.
Mine got 44 degrees celcius yesterday.. not really good for our phones I think.
The reason I use setcpu is more to control overheating than improving battery life. You can set it to underclock whenever it gets to a certain temperature.
Hi.
While playing games my Xperia Play produces lots of heat. The back of the phone, and the gamepad feels really warm.
I checked the temperature with Battery Monitor Widget and when I don't use the phone it stays around 25-30 degrees Celsius, but when I play games (even 2D ones) it goes up to 38-40.
Is this a normal thing or there's something wrong with my battery ?

I can confirm this happens. Basically it is using more charge, therefore as a side effect of that it produces more heat from the chemical reaction. Same thing when you have it charging.
It isn't horrible, but try not to let it get too hot as it may shorten the lifespan of the battery.
So this is true for all xperia plays that after some time of gaming the phone will be really warm ?
The phone will get warmer, of course... but 40 degrees is not excessively hot. It feels warm in your hand, but it's not dangerous. A dangerous temperature would be close to 50.
The highest temperature that I had was 44 degrees after a long Nova 2 session.
I am a bit worried by the fact that while browsing the net through wifi the battery heats up to 38 degrees, but it's okay as long as it's less than 50 :> ?
Thanks for the help.
I'd say if it goes above 46 or 47 you just switch it off for a while. Not only because you don't want to overheat it, but because running the phone on higher temperatures reduces battery life (higher temperature means higher resistance to conductivity for metals).
Thanks for the into that it's perfectly normal for the phone to feel warm.
Have you ever reached 50(or that 46,47) degrees on Xperia Play or any other phone ? What app made your battery that hot ?

My former phone, the Galaxy S had HUGE issues with temperature while using 3G. Every time I toggled it on, the phone became awfully hot and the battery drain skyrocketed. I got it on 53 degrees once, since it was in my pocket. I was a bit scared, but the phone resisted it. Still, it wasn't pleasant.
The advantage of the Xperia Play being bulky and plasticky is that it's hard to bring it to extreme temperatures. If it's hard to make it hot, it has a positive impact on battery life as well.

Yea, this happens to me all the time. When using anything that drains my battery it heats it up as well.
All batteries release heat as current passes through them. When the phone is idle, the heat released is low enough your hand doesn't feel it. As the current increases while gaming, so does the heat.
It's nothing to worry about. The batteries are designed to handle heat without being damaged.
Especially since android devices are becoming more popular in places like india, where there's a lot of ambient heat.

Seems the Nexus 6p has a cold bug. First phone i seen this in.
So i been doing some overclocking and bench marking on a few devices. The Nexus 6p has shown some strange behavior. When i had the phone chilled and ran some benchmarks the battery would drop drastically. Restart and all that did nothing. The batt. stayed at 39% for about 2 hours with some heavy use. Charged it back up no issues. Did it again and it did the same thing. Took my turbo 2 to an even lower temp and that was fine it did not have this.
Something you have to worry about? Nope not unless you are out in Alaska or taking a trip to the artic circle. However if you do this could cause you some issues.
Tested on a stock room and kernel. As well as a purenexus and elemental x combo. Same outcome.
Again not really an issue. And the Nexus camera visor and display survived the -40c freeze and back to room temp test. Attached is a pic of the massive drop
Not sure why the Droid Turbo didn't demonstrate this same behavior, but extreme cold temperatures definitely have an impact on lithium ion batteries. Perhaps the material of the Droid Turbo insulates the battery a bit better than the aluminum on the 6P?(pure speculation there - science geeks, feel free to rip that one apart)
I've experienced the same thing with my DSLR (Nikon D80) when shooting in the cold.

Yeah the turbo 2 was even exposed to cooler temps longer. And its not that the capacity was lost. After the bench it would stay at that + for a few hours before it started going back down. So when i started at about 74% after it still had 74% less just android was saying that it was lower. I still managed to get a full charge out of it. Not an issues just a omg my batt is almost dead. Fallowed by omg my battery has been at this % for a few hours.
-40°C isn't really common weather and is definitely out of normal range of temperatures. I live in a area where it gets cold (-30°C) during wintertime, I don't really use phone in a such coldness (my fingers would freeze pretty fast anyway.)
I once answered phone in -25°C (current phone at the moment was Sony Ericsson W910i) I talked for 15 minutes and my battery went from 100% to 21% and shut down moment after the call ended.
Don't all batteries exhibit fluctuations in total output in extreme situations high or low? I use an iphone in a work truck that is left outside in 20f to 30f temps and that thing is crazy swinging from 100% charged when I leave it in truck to dead in one night in cold temps.

My nexus 6P sorta died on me today, it was stored in my GF's bag, we were outside, 0F, for like an hour. When I go to take my phone, won't turn on, tried plugging it in, nothing.. could the cold weather (not so cold) have killed my nexus 6P ? Anyone has had this problem ?
I live in northern Finland and I have experienced this kind of behavior with my 6P lately. The battery dies suddenly under -10 C degrees if I keep it in my pants pocket. This is daily problem so have to wear my phone in wool mitten and then pocket it.
I think this started right after 7.1 update. My phone is 12 months old so it might be the battery losing its best edge or simply software feature/bug.
The battery model uses inputs from current flowing in/out in the battery, outter voltage and battery temperature sensors and calculates Open Circuit Voltage leading to the estimated State Of Charge (by use of a 3 degrees polynom)
As any resistor, the internal battery resistance will vary depending on temperature. So will the OCV calculation.
All these parameters are linked non linearly and the models are done within temperature ranges (different coefficients for say different temperatures). If temperature exceeds thresholds ( /sys/class/power_supply/bms shows a nominal range of [10 degC, 45 degC] ), the SoC will not be computed.
If temperature exceeds thresholds or SoC varies too widely, the battery current will be downlimited, meaning it won't charge as expected or could shutdown for safety reasons.
If battery temperature goes under 5 degC, the SoC is considered invalid.
As such when starting again the device within this range the SoC will be calculated again correctly and the device will stay on.
There are also high/low safety thresholds which will instantaneously shut off the device (I think they are stored in the Qualcomm IC so I can't see these values).
So while the battery can probably work fine under 5 degres C, the SoC won't be calculated properly. You can also get some feedback from the known battery health in /sys/class/power_supply/battery/health (Good, Dead, Warm, Cool, Cold, Overheat, ...)
I've gathered this information from the Qualcomm IC driver source
Sound like a Overclocking CPU with Liquid nitrogen haha.
This just happened to me today. I was out skiing and temps were -10 f. Phone shut off in less than an hour after starting from 100%. Went back inside, warmed up the phone and the battery was stuck at 39%. I moved my phone to an interior pocket closer to my body and didn't have a problem for the rest of the day.
As a avid skier, I can say I've always had extreme cold weather issues with phones, but the Nexus 6p is definitely the most severe.
FYI I'm on 7.1.1
This happened to my Nexus 6 today. I was in the garage (non heated) working on my car and had my phone sitting on a box next to me. It was about 30°F and I grabbed my phone to send a picture of something to my friend. As soon as I launched the camera it shut down. It booted instantly after pressing the power button, but after being on for about 15 seconds the battery percentage displayed in the status bar suddenly went from 51% to 0% and it shut down again. After bringing it inside to warm up my battery was back to 50%.
I've also taken my phone snowboarding in much colder temperatures and never had this issue. Even while using it on the chair lift where it's directly exposed to the cold and wind it's never shut down.
The only thing that has changed between past usage in cold weather and today is the version of Android I'm using. Unfortunately I'm too lazy to revert to 6.0.1 to see if that solves the issue since I just did a clean install of 7.1.1 about 2 days ago...
What count is the battery temperature not the ambiant one. You can use "cool tool" or wharever app to display that. If you're rooted you can even check the health file I mentionned (to see if it's Cool or even Cold from the model perspective).
The are linked by discharge rate.
The theorical unusable capacity will increase at low and high temperature but also with discharge rate. So if you are at these extreme temperatures, you could try to lower the discharge rate as much as you can by disabling all what you don't need (sync, lte).
Anyway at -23 degres ambiant your battery was maybe at -10 which is outside of its theorical range. We don't know the practical performance at these temps. I'll have to check again to confirm the low temp threshold at which the SOC is not calculated (think 5 degres that is ambiant 0 or -5). Could be that the battery is ok but the software lacks a lookup table at these ranges. There could be a reason. Anyway, I would try to preserve the battery from these temp if you can.
I have the same issue - but in +3 or +4C degrees. The battery went from 60% to zero in 15 min.

Ambiant or battery temperature? If the former, you'll need to know what the battery temperature was. That's the only thing that matters here. I guess you were talking about ambiant so the device once switched on could be at like 8 degrees so I'm surprised about your results.
I use Cool Tool but you can also use any other app like... Battery. What's relevant is battery temp AND battery health (Good, Cool, Cold ).
I've just put my phone in the fridge for some testing. Should be around 4 degrees also
OK usually my CPU hardly ever exceeds 60c. Only when charging and watching YouTube at 60fps. Usually when browsing it remains 45-55c and no more. But it decided to stay at 59-64c over the past 20 mins and peaked at 68c. I went into dev settings and enabled CPU monitor and found twitch was causing the CPU to overheat (more than the s4 does already). I uninstalled it and. As I type this I'm around 44-47c. Was that really high temperature, and the relatively high normal operating temperature damaging to the phone. Or just uncomfortable to hold?
The top part of my screen has a darker tone than the bottom part. It's hardly visible in most cases, but there are time when you can clearly see it.
Don't know about the motherboard and such, but I'm pretty sure this screen tinting is a result of the heat, since it's the top part that always gets hot.
But I'm also a heavy user - I use the phone from morning to evening and the screen is pretty much on all that time during that period.
To exemplify: I woke up like 6 hours ago and the screen was off maybe a total of 30 minutes in those 6 hours.
So maybe the heavy usage + heat is what caused this degradation.
Anyway, this is bound to happen at some point anyway, regardless of usage and heat - that's the nature of AMOLED - though the process may be accelerated by using high brightness and the aforementioned heat.

Good morning,
I want to ask about your devices' temperature.
I attach a screenshot of my device's temperature in idle state, light usage.
Every sensors are around 35 degrees Celcius, battery is around 32 degree Celcius.
On surfing Facebook, Instagram, Youtube...etc it can rise to above 60 degrees & battery rises to ~37.5 degree Celcius.
The device is warm, sometimes hot (but not hot to touch) around the area of fingerprint scanner.
Is it normal? Do you experience the same?
My device is a Korean version.

Yes. Actually experiencing the same. This is also a Korean version.
It is not too crazy hot. But I think it does get warm a little to fast for my taste.

the same issue for me! can't be normal for a top level smartphone :/
I have the T-Mobile variant and it gets warm. But never to hot to touch. The only time it ever gets close to that is when charging in the car. I use the Anker QC 3.0 car charger so I assume that's why it gets warm. Plus the sunlight.
I've had a few glass phones and I've noticed they feel warmer than normal and I can only blame it on the natural heat dispersion that glass has. Whenever glass is warm at all it always feels way hotter than what it is. With the cooling system in place that is why you feel more heat around the fingerprint scanner and on the side of the phone it's just doing its job
Also if you are using a case and you take it off and it's super hot/you feel the heat through the case it's probably because of the case trapping heat in the phone. I almost always charge my phone caseless or with my fan blowing on it since the phone is designed and tested without cases.
Try closing all apps while it charges maybe try a new case? Turn down your brightness or something. If nothing works maybe try a warranty replacement. It's possible your cooling pipe is defective
Snapdragon phones have run too hot for a while now, this one is no exception. It's always warm or hot to the touch, even when it's idle lol.

Mine too..h870ds..not hot but warms..only doing light activities..surfing web,insta,twttr..is there anything to worry about?the warm feeling arise at the fingerprint scanner and camera part..
Those who are having hot G6 Try wiping Cache in settings-storage and do reboot.
If not Format the entire phone and install apps from playstore NOT from backup you have made

Phone Speaker gets hot when full volume
The only time my phone gets hot is when I listen to music on phone speaker with full volume, for some time. The speaker area gets hot.
Other than that with web browsing, Youtube etc not even warm to touch. (Also I have a case on, if it affects anything)

The speaker will warm up but that's because it maxes out at 4w which is insane for a phone speaker other than that ive played 3d intensive apps and my phone doesnt get above 38-44 degrees Celsius. Love this phone
My phone does never get warm :/

Same issue
If you are still having issues with a warm / hot phone, I'm curious what OS / flavor are you running ? I haven't tried a custom rom yet, I'm still on stock and it takes a lot to get my phone hot.. it's even stuck inside an otterbox which can't help with the heat being cased in plastic lol.
--edit, I ask because I want to move to a custom rom but don't plan on it if it's going to make the phone hot idle !

I'm really curious to know, when everyone complaining about warming and heating up u say it barely heats even in summer.
Please let meknow, outta curiosity, i wanna know.
Which country do you live in and by meaning hot summer, how much is the temperature during summer and where do you use your phone like, Air-conditioned environment or under a fan, or just using the phone under the mentioned environment without any ventilation. It'd be more helpful for me to further raise a concern with LG if mine is misbehaving!
