Hi guys,
I've been noticing the battery temperature hitting 38-40C when charging my phone through wireless. Is this normal? The temps hit that high when charging from 20% to around 80% and then I believe it starts to go down to around 34C. I tested my turbo charger and the max temp it hits is 36C.
The battery can handle much higher than that.
Just concerned because I know heat is the number #1 enemy of these batteries.
Get worried if it goes over 50

have a Nexus one running Cyanogen and the UV UC Kernel from persian.
I do not have setcpu to run it overclocked but have setcpu to run at normal speed, and with prolonged use the temp can reach 94-98 degrees. Standby etc it runs upper 70's.
Problem I am having is that when I run it in my car using a car charger and with GPS running it quickly hits 99 degrees. Mind you that setcpu is under-clocked it to 763 while it is charging. I have my failsafe set to 98 degrees and it goes to ~650 but the temp still rises albeit slowly.
What is a dangerous temp for the phone? I have not had any adverse effects, but I believe with my 98 degree failsafe setting I am being very conservative.
Has anybody watched their temps while charging and using to see what temp you phone stabilized at? modded or un-modded?
Nearly 106. But now I've got an Air Vent holder for the phone and it stays pretty cool. Don't remember exactly what temp it was, but I believe that it stayed in the low 80s (with music playing on top of GPS & plugged in). Haven't used GPS lately.
+1 I did notice my battery was abnormally hot when I run GPS. My failsafe is 40C or about 100-102F... Usually over that FC's the Phone or makes it hang. At least my experience.
Thanks, I did notice this evening that my phone hung up after exciting Copilot a couple times. I could open up any icon on the home screen but it would not scroll, however the temp was only about 96 so I am wondering if it was more of a problem with co-pilot. I also ran pandora and copilot at home for over an hour hooked up to the computer and the temp only hit 91. The phone still gained positive charge but not very much. I might try getting a USB charger and slow charge in the car instead of the 1a car charger I am using now.
Hello guys!
My Razr i sometimes is so warm, I installed an application to see the temperature of the battery and when I'm not doing anything it's 29-34°C (84-93.2°F) and when I use facebook, listen to music and surfing the internet simultaniously the temperature increases to 38-41°C (100.4-105.8°F) What I know is that batteries must not be exposed to temperatures higher than 40°C (104°F)

What do you think, if your theory sustain, how could people near equator get along with mobile phones? The max temperature for Li-ion batteries is 45 degrees C when charging, and 60 degrees when discharging (use).
Some background on the Nexus 6 that I've owned for 5+ years. Battery life was fairly stable for ~3 years. There were occasions where I played Clash of Clans while quick charging that the phone got scorching hot. So hot that I couldn't hold it against my skin for more than a few seconds. After regularly doing that for a while, the battery degraded to less than half its original capacity.
I bit the bullet and bought a replacement battery. I made sure to get a good quality one, not a cheap Chinese knockoff. I tested the capacity of the new replacement battery and it was close to the original battery's new capacity. However after about a year of clashing and quick charging the phone to stove-top temperatures, the replacement's battery capacity degraded severely.
My friend's N6 suffered similar battery degradation during a road trip while he was charging it in the car, using map GPS, and playing music. The phone got so hot he had to hold it in front of the AC to keep it running.
I like the screen enough to where I'm considering replacing the battery again. However this time I want to prevent it from overheating. Is there a way to disable quick charging in the firmware? Which firmware aggressively throttles CPU to keep temperatures down?

Not shure if this is what you want, but I implemented power profiles in LineageOS 15.1 and 16.0.
You could use the Effcient or Power Safe profile in situations like you mentioned.
Why not simply use a power adapter that cannot deliver much power?
And not wireless charging - that always creates more heat.

That sounds great. My N6 is currently running Lineage 14 and I only see Power Save. Is the Efficient profile better? Power Save makes the phone run quite slow. It'd be nice to have a profile that adjusts performance based on temperature. When it's cool it runs faster, and as it heats up it slows down.

I use a standard 10W charger at home (5v @ 2.x A). However when I'm on the road, visiting friends or traveling, I may have to borrow someone's charger, and it might be a fast charger. It would be better if the phone throttled its charge rate based on temperature.

Oh I can't remenber what the Profiles where on 14.1. It's too long ago and 14.1 is far outdated. Profiles in 15.1 and 16.0 are totaly different to 14.1.
I guess a profile based on temperature wouldn't work properly, but we already have thermal limiting. That means the cpu / gpu is throtteld if a certain temperature is reached.
The charging rate is already based on temperature. But fastcharging is always generating more heat then normal charging. If you would limit it to the same temperature levels then standard charging it wouldn't be fast charging.

Thanks for the info. Is there any way to disable fast charging via firmware, or is that locked in by the hardware?

Could be limited in firmware but I guess you have to do it yourself.

Would I need to build a custom kernel, or could I send commands to a device in /proc to disable fast charging? I do app development but not familiar with the inner workings of this in particular.
Thanks bud

Kernel needs to be changed
This Nexus 6 has been running LineageOS 16 for the past 6 months and the power profile is vastly superior to both Lineage 14 and stock ROM. Great work @Elektroschmock on the improved power profiles.
I'm sure there's a custom kernel out there that will let you manually set the thermal throttle temperature. They really pushed the 28nm process to the limit on the Nexus 6 the clock speed of the CPU is 2.7ghz that probably explains why the phone gets so hot when you play Clash of Clans. I don't know what the Krait 450 cores equates to but most of Qualcomms quad core CPUs on 28nm are maxed at 1.4ghz. I'd set the CPU clock speed to 1.8ghz max and lower the graphical settings in the game that should help your heating issues.
Look guys just this year I realized what's causing the Nexus 6 to overheat soo bad look at these pictures in the link below it's because Google was Soo stupid enough to put the CPU right under the battery actually the battery is right on top of the CPU I'm like why the hell did they built the phone like this. If the CPU was far away from the battery the device would not get sooo hot and causing the battery degrade quickly because of all that heat.

I can't be the only but has anybody noticed the phone overheating quickly with moderate gaming or even an antutu benchmark. This is without X mode. When I do the same with my K20 Pro, it doesn't overheat like the Rog Phone 2.
How are you defining overheating? The device throttling? Do you receive overheat warnings?
Just because a phone gets hot doesn't mean it's performing worse. If anything it could mean it has better heat dissipation due to better contact between cooling and cpu. I play dual screen 2 games at once for 3 hours straight and the cpu remained cool around 40C. I kept my cpu speed down because it was overkill anyway

Can feel the heat near the upper left of the back of the phone. Temps were in 40s.
40s is not overheating at all. ROG phone has higher surface temperature than some phones but it's because it's barely throttling even after 1 hour of gaming. No need to worry

Exactly, it's not overheating, it's doing its job. It's moving that heat away from the internal components and to the outside of the phone via the vapor chamber, external vent, and aluminum side body section near the vent. Throw a slim case on the phone if you don't like feeling it warm in your hands, or tweak the game mode profiles to underclock the CPU and GPU and/or lower the thermal limit during games that make it heat up too much in your hand.

Agreed. It makes perfect sense that the t6ip left is getting warm, that's where the vent is
Rog phone 2 tencent edition overheating and shutting down
My Phone overheats and shuts down when under heavy load, or while charging while im sleaping. it first happened while playing pubg mobile and streaming my game to youtube. I can feel it gets very hot and after a while it just switches off. i also tried the antutu stress test and when it reaches 5% it switches off, i opened the armory crate to check the temps while antutu was doing the stress test and saw that my cpu reaches 73°c and then again it switches off. this is with xmode off.

That's definitely abnormal. You should try to get a replacement or warranty repair.

any updates. i’m having the same issue.
Same here. When I play games like ML or any games my phone overheating fast then my screen will turn off ..and another issue when I charge my phone while overheat my phone will shutdown
does anyone knows how to fix this?:crying::
I'm having the same issue. Charging overnight - it gets really hot, and sometimes it'll randomly reset. Not gaming or running much in the background. It happened since the last update prior to the most recent
Keep in mind that Rog phone 2 has a SnapDragon 855+ and + means it's overclocked. While other normal phones out there runs on default speed settings. So that's probably why Rog phone 2 can get hot quickly due to it's overclocking.
Mine gets very hot along the edges. In fact it gets so hot along the edges that it burns my fingers. CPU temp doesn't ever go much above 45 but the sides become untouchable... Is this a feature designed to stop you playing and thus save the phone from melting in your hands? ??

I had this problem on Android 10, but the problem was reduced when downgrading back to Android 9.

Yep android is a dealbreaker. Extreme overheating cause of the software.
After long time and intensive research, I found the real problem which is cpu/gpu refusing to throttle while on load. Usually the system reduces the clock speed of the cpu to keep the temperature between acceptable working range (room temperature - max of 60°c)
If cpu doesn't throttle, the cpu temperature rises until it reaches the max (i.e 65°C which is critical temperature as per A10s updated thermal framework) and shuts down the device.
I found a workaround which involves reducing manually the clock speed as the temperature increases.
But it requires tasker app(paid) and root to work.
Hi everyone,
I recently bought an S23 Ultra, after installing various device info apps (devcheck - device info HW - aida64) I realized that the Cpu temperature reaches 95 degrees in a moment ...
I put in screen sharing an app info and geekbench6
Do you think it is normal or a defect of my phone?
I add some screens.
194°F at idle? That's way hot even under load.
What's display brightness at? What's the ambient temperature? Battery temp?
168F tops is all I would go for the CPU, maybe 186F but that's pushing it for a smartphone.
Find out what's using all the power and tone it down. Don't count on temperature throttling or auto shutdown to save it from a thermal runaway. It may shutdown and never wake back up...
If the device is hot to the touch, shut it down, power it off. 140F is the top limit for the battery and that's too hot. With a full charge on the cell it can degrade it permanently.
Room temperature : 24 degrees
Battery temperature does not exceed 42 degrees.
That is the CPU Temperature during geekbench6 with cpu running at 100%

I wouldn't bench it if it's running that hot!
Lol, if my battery gets above 105-6F I shut it down.
