High SoC Temperatures - Xiaomi Mi Mix 3 Questions & Answers

so according to JerryRigEverything Teardown of the Mix 3, there is thermal paste on the SoC to lower the temps, however according to Antutu and CPU-Z sensors my SD 845 reaches 40-45 ALOT during light use; almost at idle being 36-40C, as high as 50C a couple of times, and 45-47C average during gaming opposite to my previous Honor Play which topped out at 42C after like 2 games of Pubg and ranges from 30-35C normal light use.
my antutu scores aren't suffering though my average is 295,000. (a bit higher than other SD845 phones that aren't "gaming" phones)
is it normal for SD 845? since it boosts to 2.8 GHZ
is it xiaomi pushing the SoC a bit to gain an edge? more heat due to more sustained boost for example.
faulty phone?
on the other side, my battery temps are low, like 28-30C idle, 30-32C light use and like 33-36C gaming & wirless charging

Any Surface Pro mods?

Had my pro 2 about 3 weeks now. Slightly undervolted using XTU (CPU -55, Cache -70, GPU -85). Tweeked a few settings here and there, use a different stylus and wacom drivers, but nothing major. I wondered if anyone had done any serious mods to their device to have it running better?
Could you underclock the turbo therefore while leaving a lower max potential performance increase the amount of time that it is in turbo rather than throttled?
Since it gets so hot under load and some of that heat gets transferred to the case I wondered if putting to smallish heatsinks on the main hot spots would increase the thermal dispersion from the processors. The back of the case near the vents get to about 55 deg from what I can see through searches. Those little fans really seem to struggle under load resulting in fairly regular throttling. Not sure if this would make much of a difference though. I'd seen ones that were 40 x 60 x 6mm which i thought wouldnt be too much of an additional bulk but would increase the thermal conductive area and mass.
Cut back the turbo boost and max turbo boost from 17.5W and 25W to 15W and 18W. The XTU benchmark score was reduced from 307 to 306, so marginal difference but there was 0 throttling and a max temp of 78deg. I think I have my solution to keep the temp under 80 to eliminate throttling and thus large fluctionations in fps in games.
Conclusion, lower max performance and ever so slight reduction in average performance under high load, but much more stable performance for games and other processor intensive activity.

[Q] Normal temperature

Hello, i had a at&t lg g (e970), and now i have a D850 that i bougt a few weeks ago, but since i bought ut i feel it a little warm, it isn't too hot but it still is a bit uncomfortable, and i want now if someone have a cpu temperature monitor, battery is cold, and can tell me how much is normal in this model, and which monitor you used.
I readed that it have temperature problem, but i only open for example a web page and it feel warm, if you can test it without any extra app running would great for me.
I used:
https://play.google.com/store/apps/details?id=temperature.mugich.com.thermo&hl=es
and only opened it i had at least 40 celsius, if i wait a minute it up 2 or 3 degrees.
i read some post, but i didn't see any value for normal temperature, i hope you can help me, thz
During normal usage my cpu temps are between 40 - 50c and it exceeds 50c when I play games. I think this is the standard for the G3.
Temperature
hello, thz for your answer mine start in 40-45 celsius, but if i open camera it go to 62, do you have same temperature with yours? or is only mine that have that temperature?. thz
My temperatures:
Normal use (facebook, instagram) ~45C
Camera ~48C
Opening a lot of apps sequentially ~55C
Randomly jumps up to 60C-65C for no reason when messing around with different apps and WiFi sync is open with LG PC Suite
Google Maps: ~62C
AnTuTu toped out at around 84C
I was wondering if my temperatures are high. Comparing to my friends Huawei P8 Lite the temperatures are about 60% higher. This is normal due to the 2x clockspeed of the 801ac vs the Kirin 620 of the Huawei.
Battery temp never exceeded 32C
Are other SD801 phones have such high temperatures? That's the question

Heat

Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Xiaomi Mi 5s stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.
Then, drop a comment if you have anything to add!
Which rom are you using?

heating doesn't seem to be an issue, unless you're playing grafics demanding games... overall it's acceptable
playing Implosion - Never Lose Hope for about 2hours on highest settings didn't feel any heat at all...
it just lukewarm..... SystemPanel2 reported temp around 40C - 41C only....
The snapdragon 821 in known to thermal throttle. That fact is the same with this device. When the device is at room temperature, performance is great but as it approaches 35-40 Celsius, performance decreases noticeably in order to reduce heat. Overall, it is equal to what you could expect of any device using a snapdragon 821.
Yes, the only problem I got so far is the heat. It's above average but not the most.
Yep, i feel that the heat also i didn't push harder the device yet, just internet and a few app.
Mine would heat up quite a bit before but then I used some thermal paste, Thermal Grizzly Kryonaut, on the cpu and gpu and it seems to fair a lot better now. Running PUBG for a while it doesn't go beyond about 52 and averages around 48.

why is this processor so battery hungry?

I previosly owned a Moto X Play and it didnt consumed more than 3% and at redmi pro is minimum 12% . Data and wifi always enabled

There's definitely something with the thermal management of the processor, as evidenced by the difference in Antutu scores hot vs cold where I see 30% difference, low 70000 versus > 100000 - and by "hot" I mean after 10 minutes of browsing, not playing intense games.
That said, compared to a similar spec phone like Elephone S8 the Redmi Pro looks pretty good. With a similar battery rating and X25 if I leave both idle the Redmi Pro still has 35% charge when the Elephone S8 hits zero. Yes the Elephone has a larger screen, but by idle I mean mostly just sitting there with the screen off.
Can't comment on the Moto X Play but if the Snapdragon 615 is anything like the 625 in, say, the Redmi Note 4X then battery life will blow it out of the water and performance will remain pretty much constant (it never gets "hot hot"). But... so here's the thing, in Antutu the performance never reaches the heights of the X25 at it's hottest/worst.

Oneplus 8 throttles immediately it gets to 44 degree Celsius.

Help, I got a oneplus 8 but the device throttles and starts lagging profusely immediately it reaches 44 degree Celsius, I've tried everything from custom roms to magisk modules, nothing works, I got this phone to play games but it cant even do that for more than 10 mins as it starts lagging.

(1) Does it overheat when only playing games?
(2) Does it overheat when not playing games?
Meh, load DevChek and see which if any sensors are running hot.

Only when playing, it's a Snapdragon 865 with 12gb of ram phone and it cant even play games at the lowest graphics for more than 5 minutes without lagging

There are modules designed specifically for gaming needs. Here are a few for testing purposes.
A phone’s internal temperature can be 36-43 degrees Celsius (96.8-109.4 degrees Fahrenheit) and still be considered normal.
Arguably, its fine, if anything that's considered "cool" considering the chips can withstand up to 90°+.
The temperature reading you're seeing is simply the "system" temperature. The CPU and GPU hit well above 90c on games like Genshin Impact, there is nothing to worry about as those chips are designed to run these high temperatures. If high temperatures on SoC's would have been as damaging as some people make them out to be all devices would have been dead by now, but they still run despite thermal throttling at almost 100c nonstop.
-- YMMV
Taking any sensor above 160F isn't a good idea as a runaway component frying temperature excusions (caused by temperature control hysterious) can and do happen. You need a buffer zone to help avoid this...
High temperatures and current drain trash Li's prematurely as well. Any constant drain of 800 mAh or greater will effect battery longevity. Some of these newer phones are drawing an average of 1Ah when not even gaming, ridiculous.

Thanks, I've tried some magisk modules in the past but none of them works and some of them bricked the phone and I couldn't boot up without formatting it, I'll need to make a back up before trying any of these so I won't loose files again.

The phone is fairly strong for it to start throttling at 44 degree Celsius is just barbaric, I'm in Africa and 44 is just the normal temperature for any phone, because the weather's hot

If the humidity is low use a damp microfiber cloth to cradle it in. If the battery goes above 108F it may trigger throttle back even shutdown.
It likely will not charge above 104F.
Keep it out of the sun, always. Use manual brightness control and keep it under 50% whenever possible. Optimize it and take out the trashware like FB, WhatsApp and such.
I can use my phone at 100F for prolonged times with no cooling for browsing but need cooling for vids or such as well as charging at those temperatures.
