Safe Temp Charging/GPS - Nexus One Q&A, Help & Troubleshooting

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.

Screen Off: 245-480
**Stock is 245-245. 160 as a minimum seems to produce a LOT of wait time from when the call is coming in to when the phone lights up. More than 245 seems to whack the battery.
Keep in mind, when you wake up your phone, this Screen Off SetCPU Profile is active for at least a SECOND or two. The problem is that if you have your maximum at 245, you experience BAD lag trying to pull the lock bar down. At 245-480, the maximum is high enough that a) the lock bar pulls down as smoothly as a stock Eris, and b) even if SetCPU takes a couple of seconds to change the profile, at least you're at 480mhz for the first scrolling of the screen left/right (so you don't embarass yourself in front of iphone users). Anything higher than 480mhz is a different voltage. Almost the whole time your phone is 'Screen Off', it will be operating at 245 anyway. So 480 is a good setup for it to jump up when a call comes in (to play the ringtone and show the picture a little faster, and for the lock screen bar to pull down smoothly, and the first second of SenseUI to be smooth enough, until your phone changes the profile to your <100% profile.
Battery <100% 245-806
** Zanfur's take on how this processor clocks up/down its speeds will lend itself to a general wisdom that 768mhz isn't really slower than 806mhz, and that in instances of high variability of clock speed (aka you have some Power Save bias in SetCPU keeping it lower/higher at random, or you're doing very intermittent tasks), the processor rests at 768mhz more quickly, and wastes less time/'effort' changing speeds. Changing to 806 is another 'step' altogether, where 245 to 528 is one 'step', and that to 768 is another 'step'. Going to 806 is absolutely another step yet after that (which means your phone responds a LITTLE slower because it has one more step to 'throttle' up to). BUT, if you're doing a dedicated task, such as running a Linpack benchmark (which is a terrible benchmark anyway) your phone will move faster at 806, or if you're playing a game, or playing a video... generally the processor will stick at one speed (and not have to 'step' up or down), so 806 is faster. I clock friends' phones at 768 to avoid problems, keep it clean, etc etc. Some people put the minimum here at 160mhz, but I feel that this is too low (and another 'step', just like 806 is over 768, 160 is another step down from 245).
Charing (any) 480-806
** I keep the minimum here HIGHER than when the phone is on battery, because I'm less concerned about how much energy it's consuming, and having a minimum of 480 makes the phone very snappy no matter what, from the second you touch it
Overheating > 48C 122-528
** Clock speed here matters a LOT less than just getting your phone out of the heat. This phone doesn't overheat because it's overclocked, it overheats because you run it at an overclocked speed for a long time. MOST overheating instances are from wireless tethering and from broken charging systems (that keep trying to charge the battery and generate a lot of heat). The 'Failsafe' profile here provides a 'notification' option which I HIGHLY recommend.
My ex-gf's Eris actually CAUGHT FIRE, as in it looked like it was a zippo, right above the volume buttons. It used to overheat EVERY NIGHT that it was on the charger, excessively, so hot that you couldn't touch it. For a month or two it did this, actually, and caused no real damage to the phone. Since the night of the Flame (you can actually see the melted plastic and even on the outer case - she has a blue snap shell case on it that is melted as well), the phone has NOT overheated even one time on the charger. (Sorry for the story, it was a waste of time).
The point is that, the first time it happened, her phone System sound was on Silent, and she DIDN'T hear the notification that her phone was overheating. Apparently it doesn't matter (or she's very lucky her phone isn't damaged in terms of its operation!) how much it overheats for some people, but I like to have it warn me it's getting close to 50C. The notification's the important part there (so u can cool your eris), not the clock speed.
@pkopalek I like your settings you posted with a full description of each. I changed my settings to yours and give it a day or so and will report a status update as to performance quality
I've never lagged at 160mhz =p but that could just be my phones/ roms.

my audio skips and it won't wake up when in a call at 160mhz. I keep mine at 245mhz minimum to keep phone working smoothly.
What does the different prioritys mean? Is that like what one its.focused on more?

How do you guys clock your CPU so high? Whenever I try anything over 729 bad stuff happens. If I put it on 748 it lags and if i try 768 it freezes up. You guys are all using the droid eris right? What ROMs and kernels are you running? I'm on Kaosfroyo

When a processor is made at the factory, it will always have flaws in it. The chip is tested to see what frequency it is stable at. So that is the speed that is stamped on the chip and the frequency that it is set at to operate for the consumer and not have any problems. When you overclock a processor, you are bypassing the frequency that the chip as been deemed to be stable at. After that, there is no set speed that your processor can handle, because each one is different according to the flaws it might have.
So in short (what I'm trying to say), the processor in your phone just can't handle those without causing problems. That's why when you overclock it, it's kind of a trial-and-error process to see what speed you can get out of it, but be careful, because too high can cause permanent damage.

[Q] Overheating

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).

[Q] Normal device temperature????

hi
What is the normal device temperature that you see.. I m not talking abt the battery temperature.. I am talking about the device temperature ...
I am checking the device temperature using the cpu temp app
The normal temperature that I noticed when I got up in the morning was 32c
It is with wifi ON and brightness set to auto and normal 2g
after some minor use the temp now is 40-45c
If I do a 4k recording for 2 minutes.. It becomes really hot and temp goes to 70c
If I play a game the temp goes to 55-60c
While running antutu benchmark it restartEd once... He temp was around 65 for some time
while charging the temp is around 50c?
The device screen really feels hot , even more then the leather back
So are these things normal?
Or is this some hardware problems
I have already checked the battery stats and don't see anything unusual hogging the battery
I have not installed any apps.. Just the ones for speedtest, antutu, cup temp etc
Awaiting replies
Anyone... Any replies... At least the average device temperature
So many views...but no replies...
Ran antuntu and it capped at about 62C. Chill and uninstall the temp apps and use your phone normally.
thanks for the reply.. also can you check the temp while shooting at 4K for couple of minutes?
There is no such normal device temp. The device temp depends on the battery temp. If its between 10-15° c above the battery temp. Then its pretty normal in running conditions ... If the battery temperature rises then automatically the device temp will rise ... In most of the devices its between 40-45°c .. The normal device temp. And 1 more thing the device temp also depends on the type of ui u r using

You just said there is no normal, but the normal is 40-45°. It also depends on the temperature of your surroundings. I love in southern California and have to mount my phone in front of my air conditioning because our summers were up to 44c this year. I once had my Nexus 5 shut off from heat when it wasn't in front of the air.
Anyways. You're fine buddy, processors throttle at a certain temp and also shut down automatically around 75-80C.

Wireless Charging

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

Overheating quickly

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.
