Liquid Cooling in the S7 - T-Mobile Samsung Galaxy S7 Guides, News, & Discuss

Now that I have your attention I'd like to talk to you about our lord and savior....
Seriously though, let's talk cooling here. The S7 has some nifty features in this arena. Do some benchmarks and you'll soon notice that this phone gets hot very quickly. More so than the S5 or even the S6 (used mine as a hand warmer once this last winter). This should be a bad thing, right? Not really.
The S7 has a heat transfer pipe in it, a copper one. Similar to what you would expect in a laptop. Cool, that's nothing crazy and should have been implemented a long time ago. What about this liquid cooling? Well Samsung set up an interesting system here where the phones cooling system pulls moisture out of the air and then evaporates it to aid in cooling. While this isn't true liquid cooling (there's no liquid circulating in our phones sadly), its a form of it called evaporative cooling. I have no numbers yet on how much cooler the SOC remains under load but I would suspect the heat exchange pipe alone helps immensely.
I'm trying to find a decent photo of it and I'll update this when I do. Until then, Google is your friend.

I seen some photos in a review where the guy punctured it to see what was inside, which was obviously nothing (actually gas).
EDIT:
http://bgr.com/2016/03/03/galaxy-s7s-liquid-cooling-system-doesnt-have-any-liquid-in-it/

I wonder what gas it is? I did some tests last night and many sensors showed the phone getting hot, others didn't. I just don't know where each one is located and what part its measuring. Once I killed the test it cooled off very quickly which I think is more what they were going for rather than keeping it cooler longer.

My gf pre ordered her GS7 from bestbuy... we're gonna go see if she can pick it up right now.

I think you might have posted that in the wrong thread. Maybe you were looking it the preorder one? Unless of course you were planning on seeing how fast this nuclear reactor cools off after pulling all the control rods for a bit....

oh **** lol i meant for this to go into the best buy thread...but, she ended up getting her phone and what not..

Ive been with the phone for 5 hours now and have taken notice to how HOT this device heats up to. It heats up doing literally "normal" navigation and video watching. However, It does cool off pretty quick though. May be what the headline was referring to. My concern is how many processes are going on in just normal tinkering with my device? Does it really need to heat up this quick? Are the bug fixes coming soon? Wanted to take off the battery cover to cool it down but cant obviously.

Mine heated up while setting up. It's fine now.
It even took several restarts to upgrade Google play services and some Google apps.

I think it's meant to heat up quickly due to more efficient heat transfer. Copper is a very efficient medium for heat transfer which is why it's used in computer cooling, cookware, and many other things.
The more heat that pipe heats up (or rather, the more quickly it can) the better. Next time you have some time put this phone through some demanding tests and benchmarks. Use something like AIDA64 and watch the thermal tab. You'll notice that many of the phones thermal sensors hit 37-41C rapidly but once the load is taken off the hardware they drop down 8 to 14C or more in a matter of 20 or so seconds. That's ~46 to 60F for those that hate math. That gives us an average of 0.4-0.7C or 2.3-3F per second.
On a side note can anyone help me map out the thermal sensors? There's quite number of them on the S7 but their names don't exactly tell me where they're located except for a few.

Is the Nexus 4 really overheating?

I know many people have been saying the low benchmark scores on the Nexus 4 are due to "thermal throttling" but I don't really believe this. It's supposedly based on the optimus g, and if that doesn't suffer from this thermal throttling issue, then why would the Nexus 4? I personally believe it's just due to the software. People are also saying that an update won't boost the performance by that much, but I'm not sure what to believe.
So do you guys really believe that the nexus 4 is over-heating and under-clocking itself, or do you believe it is just in need of an update?
It may be a faulty unit from that reviewer, I only recall one review saying it overheated. The software is also to blame. I made a post in another thread about the performance with these pre-release software versions the reviewers have.
http://forum.xda-developers.com/showthread.php?p=33634026#post33634026
Unfinalized software on all these review devices is probably the bottleneck. Not to mention benchmarks have zero bearing on anything ever.
And Testing units and software do have a tendency to carry heavy logcats and monitoring software... I remember from the ICS days how "heavy" most leaks would run progressively getting better by the update ...

Whilst benchmarks shouldn't matter too much, when this beastly specced phone is getting worse scores than the msm8960 with adreno 225, then it will obviously raise some concerns.

Also, another thing I wonder is this: is it called the nexus 4 because it has a 4" (4.7", I know) display, or is it called a nexus 4, because it is the fourth nexus?

I wouldn't say I'm good or experienced enough with Android smartphones to decide whether or not it's due to software, but I sure hope it is. I'm really only judging this particular issue by what everyone else is saying.
In regards to the sceen size and "Nexus 4" theory, I agree. Nexus 7 and Nexus 10 are a good example of device names in correlation with screen sizes here.
just wondering why did google name their nexus phone 10 wbefore the fourth one
I think it all came from a comment at Anandtech, they attempted to run all the GLBenchmark tests one after another, most web sites just chose 1 or 2 tests, usually Egypt HD. Most devices crash when trying to run all GLBenchmark test serially, it does on my Nexus 7, something to to do with running out of memory allocation.
Nexus 4 in a kind of suicidally awesome way completes the entire GLBenchmark suite in one go, but running all those test including offscreen & onscreen is a long brutal test, maxing out the SoC in a way no game is likely to do, so the fact that the device is thermal regulating itself is not that strange.
If Anandtech tested individual elements of GLBenchmark, as most other review sites do, this issue would not have occurred. In fact they admitted that the Optimus G could not run all tests consecutively, so they only tested individual elements, hence no the device didn't get downclcoked due to thermal limits. It is not good that Anandtech has this disparity in testing methodology, I like the website a lot, but some thing recently have led me to question a few things, but that is another story.
Every phone overheats nowadays so there's nothing different with the n4.
This is pretty interesting
Benchmark comparison. Once at room temp, once in freezer. Freezer scores are significantly better
http://techie-buzz.com/mobile-news/...es-show-the-real-power-of-the-s4-pro-soc.html
So yeah... Kinda does look like pretty bad thermal issues Hopefully just cause it was pre-release or something

But they singled out the Optimus G, because it was unable to complete more complex tests because of crashes.

Wow, that is a very interesting find. I was actually thinking that someone should do a freezer test just see if it is overheating. This article would seem to prove that it is. Those retests show dramatically higher scores, more on par with what the S4 processor should be capable of.
They said that perhaps the retail versions will have a higher tolerance for heat because they did not think they felt that hot. More testing and info is needed though.

To elaborate, straight from the source, in the Anandtech podcast this morning Brian commented that the phone seemed to be set to throttle at 60 degrees (for the dual-krait S4 at least it's usually around 80 afaik) and at that point the exterior of the phone was much cooler than a lot of other phones. (He talks about it at about 00:51:00.)
Something to think about.

That means it's a simple tweak, and so as long as people aren't noticing excessive heat (which we would have heard from reviews) on the phone itself then is sounds like things will be fine for the release.
Yes IT FREAKING OVERHEATS

I've had the phone for five days now and it definitely overheats. The last time it overheated was this morning. I got up, looked at the phone and unplugged it from the charger. Went to attend to my toddler for 20 mins and came back and saw that the phone was very warm and battery life was hit 20 percent. I did a check on battery usage under 'battery' in settings and saw that the playstore app had sucked 50% of the power of late. This is HIGHLY unusual becuase usually the screen is what sucks the most juice. I turned it off and turned it back on and it went back to being normal. During this overheating the phone stutters EXTREMELY visibly. Probably due to the massive thermal throttling of the cores. Once it cools off it goes back to being normal. This happens randomly and occurs once or twice a day. I've reported the bug to google. Otherwise the phone is superb.
That sounds like the Play Store app is misbehaving. Have you tried clearing the data?

Remember it's winter at northern hemisphere. So overheating might not be obvious.
Any friends in southern hemisphere (Australia) wanna chime in with their temperatures?

Same thing happened to me earlier today, I unplugged the phone from the charger and was extremely hot. I panic and shut the phone off. I rooted the phone last night so that was the only thing I did differently. I've had the phone for almost a week.
I also noticed the battery was draining way too quickly.
More like rogue apps... had the phone for over a month now, heavy usage every day and never once has it "overheated"as people say.
If im multitasking, like listening to music, downloading a torrent in the backgroud while playing angry birds or something the top back of the phone will get warm, but nothing unbearable if i deliberatly grab and hold the phone at that spot.
It's a glass phone... it will get warmer than most people are used to... its bascially the same glass that the new kitchen ovens use as a top surface... if you can cook on a glasstop stove... a phone heating up will be the same principle, albit on a smaller scale..
So yes, for the people complaining about heat.. then say in the next breath that they lost battery in some % form... funny how nobody is telling what they have installed as extra..or post screenshots of the battery page to back up the claim with info so we can help...large loss of battery % right away points to a rogue app somewhere.. you dont magically lose 10-20-50% whatever battery when unplugging the phone... thats something stuck running that is forcing your cpu to run at max for an extended period of time.
so as the internet expression says "fraps or it didnt happen" (screenshot or it didnt happen) lol
I am seeing battery temp reach 40C during antutu benchmark test running 4.2.2. Looks like it is only affecting a few devices. It gets warm during the benchmark test but nothing like unbearable heat.

[Q] Is it normal that the phone reaches THIS temperature?!

Hello, I've got my Nexus 4 from this Monday but only yesterday I noticed that it warms up a little too much.
Today I tried a "Classic Stability Test" to see how much the CPU and the battery warms up and after 7-8 minutes... The phone was like lava! Battery was at 50,7 c° and the CPU at 84 c°!
With games like GTA Vice City I got like 46 Battery and 64 CPU, and this should be normal, right?
P.S. I live in Sardinia, 30 Degrees today...
lol well.... is running stability test part of your everyday routine, and something you require to be able to do with your phone? thats like putting a brick on your gas pedal with the car in neutral and getting a little bit worried that the engine temp is rising.
on a more serious note, 64* is fine, more than fine for every day use. games like gta will probably stress your phone as much as anything youd do on a regular basis, even nova 3. mainly because gta optimization sucks, so it still strains your cpu as much as games with better graphics. 84* is getting up there, but lg didnt add a thermal shutdown limit just for the hell of it. you havent hit it, so you havent damaged anything.

In all honesty, I have no idea what the limit is for the battery, I don't even care about this "too hot" nonsense, you should have seen the amount of threads we had on here a few months ago. I do know that 80* is pretty warm for the CPU, but still pretty far from even beginning to damage anything. The thermal shutdown for the CPU is 100*.I don't worry about battery temps, I've left my phones in my car on a hot summer day and it pretty much burned me when I picked it up.... everything was fine. Is that kind of stuff good for it? no. If someone snuck in my car, and brought it into my house and it was completely cooled before I touched it, could I notice that something was funky with my battery? hell no, any difference from any kind of battery abuse on any of my phones has been completely in-perceivable.
Brand new nexus 4 batteries on ebay are really easy to find. And cheap (all things considered). At 40$ a pop, I'll pay that a year and a half later than letting some kind of OCD drive me insane lol, To add fuel to this overheating scare everyone has, I've had my thermal throttle completely disabled since I got my phone, 6 months ago.
Electronics have ALWAYS produced heat, that's how they work. But now, having a quad core 1.5ghz processor in your pocket, that isn't even air cooled, you WILL feel the temperature. That doesn't mean anything is wrong. I dare you to open up your computer right now, flip it off, pull off the heatsink and touch the processor. You will get burned. But that's how it runs, and you never would have known if you didn't feel the heat coming through the case or touched it for yourself.
Sorry for the rant, but yeah, your good and in the clear... long ways to go before you cause damage lol
edit: looks like batteries are closer to 20$ now, they used to be around 40$

im glad i dodnt have to reply to this, that someone else answered, lol! but seriously, if the phone overheats, battery or cpu, the phone will turn itself off as a safety, to cool off. anything below the safety temps isnt overheated. when things get pushed, itll heat up, thats jusy how things work. and if the surrounding air temp is warmer, the phone will heat up quicker and warmer.

dont be. there is a lot of misinformed people out there, that just dont know, that publish blogs and posts that end up scaring people for no reason. the thing with the n4 is the "being able to feel the heat", thats what freaks out many. its all because of the glass. my other devices(galaxy nexus and nexus 7) get much warmer than my n4, but you cant feel the heat because of the plastic backs.
Sorry again but this is what i obtained after 20 minutes of Vice City.
OK, Maybe it's the game bad programmed but this can't be "normal".
I've 15 days for ask for a new one, star should i do?
P.s. I just coocked the CPU of my PC like 1 year ago, it works but it got some damages. I really don't want to burn anything else

its hot, but could be normal, especially while playing cpu and gpu intensive games. i play lots on my n7, and i can reach 85C easily when gaming. so its not out of reason. the safety is 100C for cpu, when the device shuts itself down to cool off. out of curiousity, were you plugged in?

[Q] LG G2 Operating Temperatures

Ok, I searched the forum about this topic and didn't really find anything answering my questions. I'm currently coming from a Droid RAZR and it ran hot to say the least. I can't get a straight answer on this phone's operating temperatures and I'm trying to determine whether to put a thick case on or not(with almost no bezel, I'm paranoid it will break on first drop). From what I've read, about 60% of people aren't reporting very much heat. The other 40% say there is a huge problem and most have had to replace their phones thinking it was a defect.
When it came to my RAZR, at rest with a case on, battery temperature would sit at just under 87 F. Under heavy use, I've hit over 124 F. Without a case, 83 F, the highest I've hit is just under 117 F. Extremely significant when you can't remove the battery and swap it out. I believe that it led to it's premature failure. I want to avoid that with this phone.
Is anybody keeping track of their phone and battery temperatures?
What apps and/or widgits do you use?
What is the normal at rest temperature?
What is the heavy use temperature?
Thanks everyone. My phone gets here in a few days and I want to be ready with a case.
I don't keep track of it. However this phone does get really hot (uncomfortable to hold) when playing games. With Tpu cases this was less noticeable. But lately I installed skinomi stickers for back protector, and it always bother me when it gets hot this way.
That being said, normal uses such as Internet, music, YouTube, xda, camera.... The phone only becomes slightly warm.
-LG G2
I keep wondering why no one makes cases that help dissipate heat, for how hot modern phones get! If anything, most cases insulate the phone and make them get even hotter!

Admittedly, I'm not a gamer but the only times I've felt the device get hot enough to register with the Incipio Feather case were: 1) after a wipe/flash, and all my apps were downloading again from the Play Store and 2) when wiping and the device was plugged into the wall charger (CPU temp was around 100 degrees) - other than these 2 instances, I've never felt heat thru my Feather case.

I was actually looking at getting the dual pro. Thanks for the feedback. Exactly the type I'm looking for.
Honestly i just replaced my phone due to overheating issues. It would literally shut down or restart just running the camera for too long. After reading some other reports in the forums I decided to send it in and get a replacement. My new one came in yesterday and absolutely no overheating issues. Even can run antutu without a reboot (my other G2 would reboot about 14% in). So from my experience there was a batch that had some thermal issues... I got mine the first day it came out. Loving this second one

I use Battery and CPU-Z to check battery temps. Even with over an hour of straight gaming, I have yet to see it get above 98F. I constanty run the screen at 80% brightness as well, as that can be a contributing factor. The games I have played this long with are Riptide GP and Madden 25.
You really cant feel any heat through this case, and hand temps are too subjective anyway.

yeah, especially while gaming.. and it's not the battery drain that concerns me, the heat is ridiculous for long term gaming..
and slapping a case would be good for your hand but not for your phone
plus there's not one manufacturer that make cases for heavy gaming yet..
i wonder what the case would look like if it was made for dissapating heat.. probably has a lot of thermal pipelines built in that would be awesome..

One thing I've noticed from people's screenshots is that the screen doesn't use that much battery. My RAZR would sometimes draw 46%. I'm sure that also contributed to the heat. smh.

lol, I've actually thought about making a case like that, then I realized if there was a way to burn myself, I'd find it.

I'm currently in the design step of a case that uses tubing to disperse heat at the top corners of the phone to cool it down and keep heat away from the hand.
If you'd like to give input shoot me a pm and we can discuss it further.
OnT: I very rarely pass 24c on mine, then again I never game on my phone either. Highest I've hit was 42c during some testing.

Are you guys talking about battery temps or cpu temps?
Get the app CpuTemp from play store, it overlays cpu temp while you're doing whatever, enable only the top two options, enable overlay and start on boot.
Then get stability test app and run the first option at top, classic test.
Then report back here with your temp after you do the stress test for about 27 seconds. I hit 66c after 27 seconds.
Curious to see what everyone else hits.

Is overheating an issue when wifi tethering? I want to use this thing for desktop PC games and downloads; does it overheat after hours and hours of intense wifi hotspot use?

I have used it for a couple hours and it gets warm. Not warm enough for me to worry about checking the temperature.

Thanks for your feedback. Would you say it was with heavy usage?
I have made the tests , and i get 72 °C after 1:20 secs running the standard test. About 35 °C in idle,and about 50-55 °C when i am using the phone for facebook,browser,youtube. Is this ok? (These are Cpu Temps).

My G2 gets also around 55°C when using the phone normally (youtube, browser, etc.) and over 67-68°C while gaming. I think this is normal for a high frequency 4 cores CPU. Right?
Hey, I received my LG G2 yesterday and i've been experiencing cpu temperatures of:
42-48C being idle
52-59C during browsing, facebook, viber etc
62-64C when on youtube (after the first 5 seconds)
65C when on gps
As for the stress test after 1:20 and up to 20:00 it was around 72-74 C
The phone feels hot all the time though with no apparent reason.
Screen brightness is set to 30% all the time, 3g connection is off and I only keep Wi-fi on. I even tried turning off features like gestures, I don't know if it is of any relevance.
Of course I haven't trying gaming yet, since I'm not really interested in it, but I want my smartphone to be functional without burning up.
Should I return it and ask for a replacement? Or is it an issue with LG G2 or Snapdragon 800 generally? Will it be a waste of time?

Phone getting hot easily

As the title says, my phone gets hot really easily with simple usage. Today I was just changing my ring tones and notifications sounds and it became warm (not that hot) where it shouldn't have, with such light usage. And then I played a game for about 10 minutes and the device got hot and was untouchable. The game and UI started to lag too.
This is my replacement phone, the first phone did the same. But I think this one is worse.
During normal usage it does get hot (very uncomfortable), but it won't lag.
My phone is always above 40-42C.
Is it due to my climate?
Or should I get another replacement.
Please help me on this, I can't really figure out if it's the phone or me getting defective devices.

I had the same problem when it was summer where I am. The SD810 is terrible when it comes to heating up, and the lag you experienced is due to the chip throttling back from the heat. Is it hot weather where you are?

The weather is indeed hot nowadays. But the problem is, if the phone heats so much on simple usage, then what is the purpose of owning this smartphone..? :| I'm really disappointed considering I changed my previous device cos of overheating (Note 4).
What's confusing me is, some reviews/reports say this phone is cooler than the S6 /Edge. But my friend has one and it doesn't heat this much at all.
My dad's 6S Plus runs insanely cool (compared to my 6P).
Should I go for another repair/replacement? I've already wasted 1 month waiting for a replacement.
Everything else is amazing on this phone (except the DAC of course) .
Edit: the battery is also disappointing(like 4:30 to 5:00 average). I guess it's due to the phone heating up quickly.

Didn't you research this phone and its chipset before buying? The SD810 is well known for this. I think most reports that say the phone runs cool were written just after release, which was just as the North American winter was taking hold. You could try getting a replacement but I'm fairly confident that this is a problem with the chip.

I chose this phone over the Note 5. I heard there's absolutely no heating issues with the Nexus 6P and the 810 is implemented well in this phone.
My MacBook Pro started to heat much more than it did a few months ago too. But I can't confirm it's because of the weather because it might be some new software I installed or anything.
But the thing that bugs me is, even Yureka, a budget phone, which is known as a heater, heats only like my Nexus 6P or maybe sometimes it's even better at handling heat.
My display is very very yellow too.
This phone is literally the hottest phone ever!
Two minutes of web browsing and the upper portion would have already gotten quite warm.
I think it's getting worse lately, maybe because of the aging of the thermal compound.

Agree. I think the aging of the thermal compound is def going to make thermal throttling worse over time. Plus the thermal compound they used is absolute crap. It had a marshmallow like texture. For those able, I'd consider doing the thermal hard mod posted here. Even if instead of the thermal pad you just replace the crap thermal compound with good stuff. The phone is not nearly as difficult to disassemble and some make it out to be.
You've got a Nexus, go ahead and get your root. Custom kernels like EX do pretty well with excess heat management.
EX kicks in an optional hexacore mode just in case your phone gets mad on heat (generally while charging).
Custom kernels are great in that respect.

Any way to disable the automatic over heat screen dimming?

Is there any way to disable the automatic over heat screen dimming? I'm tired of the screen dimming in the middle of my game.

Sorry but if it's overheating then it's a safety feature.
I'm sure you wouldn't prefer to be playing whilst you're phone is on fire.
I'm short, no it cannot be disabled, which I'm glad of as people would just point their finger at OnePlus.
*removes screen overheat dimming"
after 20 minutes of heavy gaming screen dies
*blames oneplus saying very bad phone bad quality etc.*
been there, seen that. to this day many indian users remove thermal configs on their oneplus/xiaomi devices and eventually ends up with dead batteries, ghosted screen, hell some just burn their phones (x3 nfc)
Cool the phone. A fan on it and/or a damp microfiber cloth. Avoid overheating the device.
It's possible for hysterious to cause the thermal protection to fail to adequately protect the device especially in direct sunlight.
The display's thousands of semiconductors are vulnerable to thermal damage, not just the chipsets.

Slap a nice big heat sync on the back of the phone.
Problem is the battery is still going to take a massive hit every time anyway.. so you can't win really

Meh, yeah pretty much born to lose
The problem is the long game jerk off sessions on a micro laptop with very limited heat dissipation.
Limit to 5 or 10 minutes or use a gaming PC.

Turn down the brightness...
its not like i leave it dim when it automatically dims., i raise the brightness right away and do this until im done with my gaming session. Phone doesnt catch fire. Thanks for the thermal tip.

It's getting around a 100F ambient here, I use a damp microfiber cloth plus fan when charging and otherwise as needed.
I just watch the battery temp as the chipset runs cool (>120F) for browsing.

That's insane... Have you under locked or played about with CPU speeds? They don't always stick but may help.
I've seen a difference.
Are you using a case on your phone?
It'd be nice if a cooling vent was possible so we could point a solution at it, almost like a latch then have a pass through fan.
Or even plug in and stop using the lithium battery, that should eliminate a bunch of heat.

A stock N10+ snap running on Pie, brightness 30-40%, power setting: optimized, it's in a Zizo Bolt case. Optimized; no cloud storage, wifi, Google play Services, Playstore are normally disabled, and no social media apps. When I first got it it was a hot running power hog... a real menace.
At >95-98F if streaming vids* I need to cool it or give it a rest by browsing after 20-30 minutes. At 100F ambient that's getting near the 102F limit I try to stay below on the battery for best lifespan. That's what's limiting me, not so much the cpu core temp.
It's a clean running machine that's gorgeous, and gets good SOT. Samsung has given me zero incentive to upgrade it... so I bought a second new one about a year and a half ago.
*streaming vids uses almost twice the power as just surfing on the browser. Watching downloaded vids uses less as surfing.

It's already 91F here, the only reason it's not hotter yet was it's a bit overcast. That's burning off, no rain forecast for the next week, just heat.
I never use the power saving mode as it's a pain.
Oddly using peak cpu performance doesn't really add more speed than in the optimized mode.
Using max resolution you take about a 4-6% hit per hour. Even with 20/10 vision the difference is hard or near impossible to spot, mostly pointless to do.
Without a case the N10+ is hard to handle and would get destroyed. Not sure how much of a difference in heat dissipation no case makes as I never tested it. Not worth the risk.
The only bad thing with a case is spotting a failed swelling battery is hidden. Had that happen 2 years ago. Was very lucky the display wasn't damaged. Normally I take the case off every 2-3 months for cleaning as it attaches very little dust and dirt.
Always watch for changes in battery capacity and fast charging performance. If fast charging fails to engage or doesn't stay engaged within its normal temperature and charge % ranges it maybe a battery failure in progress. Batteries can fail at any time but is more likely to happen once a Li is degraded (80% or less of its original capacity).
This current Li has been hovering around 80-84% of it's original capacity for 6 months now. It's a little over 2 years old... I need to change it out soon. Lol, it's outlasted the OEM battery by over 6 months In all fairness though when I first got the phone it was a power hungry hog, took a few months to figure out how to tone it down. Another reason you want to always optimize a new Samsung; battery lifespan, not just for SOT/heat/performance.

Yea defo don't use qhd it's pointless..
Also wouldn't use power saver, I meant actually underclocking in Franco kernel
manager.
I knock them down a few notches, definitely helps.
Also with heat your phone will charge a tonne slower.. first step is 37c then 39 then 40 and so on...
Under 37c and you're getting the full 80 watts.
I think a case with some space In it would help with heat dissipation..
Android 12 also seemed to be much more efficient than 13, I've contemplated going back again and have done a few times.
Certainly shouldn't have to but needs must.

I'm still running on 9 and 10. Pie seems to run the best and is more functional. 10 has some nice tricks but has many dozens of new system apps for the UI. Oddly my disable list is nearly identical for both phones right now. That may change as I play with it more... but I really like Pie.
No plans to upgrade either. No malware on this phone (Pie) in over 3 years so it's relatively secure as configured/used.

The Snapdragon variants are notoriously hard to root. They also have a good vapor phase heatpipe on the SOC.
Not worth it as they run well now
