Tablet temp vs phone temp - General Questions and Answers

Are tablet CPU temps going to be naturally higher? My gnex and my N7 are running the same ROM and kernel but my N7 runs 10°c higher. Could it be due to screen size or am I the only person with this issue? My gnex runs at 30 and my N7 is usually around 42 Celsius.

Phone do get hotter as compared to tablets due to their size which is comparatively small from tablets. Enthu phone makers/innovators has started to produce demons which adds the heat to due to thermal effect.!!
No Solution as of now...however reports show Snapdragon series has gud thermal resistivity..lets wait once the chip is available then only able to comment further on it...

battery temperature?

i notice that when i use my phone on 4g when charging the temp exceeds 40C. is this normal? i kno this is dual core but what is the max safe temp for this phone?
I made a post about this a couple days ago and no one answered but mines usually at 94 F and 110 while charging . . i was wondering the same thing..
In my experience
I think this is just a normal occurrence in the android world. Because in both my N1 and G1 i had this same problem they would just become super hot when using extensively(Which kills the battery faster fyi) or when charging, but for charging I have heard of people using Set CPU to lower settings so that it doesn't get as hot. As far as i have ever heard though it isn't great for the phone/battery, but have never heard of actual damage coming from it.
Yes, it happens to my G1 and also my G2x. Usually when I'm charging the phone and using it at the same time, the temp would go up to 43.5C.
Extensive overheating of any semiconductor is bad and will shorten the lifespan i believe, but i think these temps should be 'normal' for these processors. Maybe there's code to tell the phone to automatically shut down after the cpu surpasses a certain temp? Like how modern desktops would.
Well hopefully when custom roms and kernels come out this will improve. My mytouch 4g used to get to 40C sometimes, but after loading up cm7, it never exceeds 35C even when OC'd to 1.2ghz

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.

Anyone had doubts between: Xiaomi Mi4C & Asus Zenphone 2 (and can share)?

Hi,
Curretnly i'm on the G3 and i dont like it much.
Thinking on 1 of these:
Xiaomi Mi4C
Asus Zenphone 2
Now, I asking that in Mi 4C Thread bc's i thinking that there is some people that might had this.
What do you think?
Thanks!
It comes down to preference really as I dont really like phones bigger than 5" and xiaomi is quite established. Its got the right size, ir blaster and a good SOC which should get good rom support, cm12.1 already available
Where are you based? The Global version of the Zenphone 2 has band 20 which the Mi 4c doesn't have (may be able to be unlocked manually but I'm doubtful). The Zenphone also has expandable storage which the Mi 4c lacks - you may already be used to this and the larger form factor due to currently using the G3. That said, I've heard (but cannot personally verify) that the Zenphone has erratic battery life and performance in addition to being more expensive than the Mi 4c.
ermacwins & wingsfortheirsmiles,
I got used to 5.5" so this is not an issue at all...
I from Israel and LTE bands are 1800 & 2600.
So from my understanding, both of them would work, right?
32gb are more than I need, so the expandable storage is not too important.
If the Zenphone do has erratic battery life and performance, it's a good reason to go for the Mi4C, isn't?
Anyone else suffered or heard on it?
Thanks very much!

Well, my Mi4C had battery drain. Around 3%/hour on idle with WiFi and 4G all off, so when I woke up a third of my battery was already gone. I ended up fixing it by flashing the international ROM but after that, I've been getting 5 hours of SoT which is great. Can't comment on the battery of the Zenfone.
Regarding the battery problem:
Looks like it could different between your's to anyone else.
I read a review in a site in my country and the person who made the review praise the battery life.
Thanks!
My Mi4c has very good battery life. The same like the z1 compact i had. Other phones i had i charged sometimes more than 2 times a day.
The zenfone 2 has worse battery life, build quality and performance. If you don't mind the SD card and 5" screen then the Mi4C is your phone. Zenfone 3 could be very interesting when (should be kinda soonTM) it gets released though!
Thank you all!
Go for the Mi4C.
P.S: A newer model of Mi series also coming soon?
How abt Redmi note 3?
No battery issue with my Mi4C. Left it idle for most part of the day with cellular and Wi-Fi connected the whole time and managed 0.7% / hour idle time. I also have many apps installed (not facebook or any messaging apps though). It's rooted and greenified, running original stable Chinese Miui 7 Rom with some Chinese bloat apps removed. It's also scoring 52K on antutu 6.

Processing power wise, ZenFone 2 (the high end 32 GB internal memory with 4 GB RAM model) is comparable to Mi4C, the GPU is even slightly better. However, when it comes to video recording, ZenFone is waaaaay below Mi4C. The still image, if you use latest firmware, is already fixed though. Note that due to the use of Intel processor, some apps that use native libraries might not be installable. Ensure your apps are architecture-neutral or have both arm and intel version available.
OTOH, Mi4C has thermal issues and I still can't find the best thermal configuration so far. This causes the cores, both CPU and GPU, get shutted down or their upper limit is decreased to lower down the temperature. I break this limit by changing the limit a little bit higher, but if you play games while charging the phone, my best record reaches 90° C. Hot enough for a sleep killer tea
Happy deciding!
Having owned both phones i can say the Zen2 is a dud. The screen is dim, the speaker is weak, some apps drain crazy battery as they are using an ARM emulator to run on x86. It wobbles on the desk and the battery dies after your lunch break. The camera has low exposure that makes everything look darker than it is. The Mi4c just works like you expect a flagship to do.

I dont believe in 90° C unless your phone is borked and termal throttling doesnt work, also phone would shut down anyway with that temperature.

It is, well the screenshot I have is 87 actually in one of the many thermal zone (they're all varying from 60 or so) but during that time I did see and feel 90 (as a hot tea drinker, I know how hot is 90). Thankfully I have a flip cover that absorbs the heat, but if you touch the scree, it's really damn hot. Thermal throttling doesn't work on my device, because I've disabled the thermal driver :cyclops:
I don't really know the actual upper limit, but I guess it should be around 100-120. My PC was 120, but I don't think smartphone's SoC will differ much.

Hahaha, worry not, it's been back to normal temp (30-50). The problem only happens if you play resource intensive games while charging.
My last phone Mi4i also reached ~90°C after playing with the thermal engine. The flashlight turned on in the pocket of my pants and burned for half an hour. I just noticed it because my leg got hotter and hotter luckily the phone wasnt damaged through this. Also, i think the CPU can handle these temperatures without being damaged, but i would worry about other phone components such as SD Card, battery or glued components
Sorry, my antutu 6 score for my Mi4c was 685xx, not 52k.

mmmh i think xiaomi mi4c only for battery

Is it possible to have a partially working processor?

It has come to my attention through benchmarks that my CPU is not performing anywhere near where it should be. It also has a -1C reading on Core 2 (technically the third core) in Synapse that occasionally flickers a temperature that is MUCH lower than the rest of the chip (like if the rest of the chip says 70, it will say 40 and it idles at 27C while the other cores don't go below 33C).
My AnTuTu is 62k and my AnTuTu beta is only 76k. In the AnTuTu beta, even the One M9 is destroying my chip (I only beat it on RAM score, Multi-Core, and 3D) - the UX scores are all about 25% under the throttled Snapdragon 810 and in the beta, the Note 5 should score almost 84k. The only benchmark that my phone is beating it on is the 3D benchmark (14602 to 13929).
If my CPU IS damaged... How on earth would I even go about getting T-Mobile to understand what I'm talking about? I mean the phone performs admirably anyway but if this isn't the performance I should be getting, I don't want to have a defective phone...

Is your phone working properly when doing phone things? Is it modified?
What software version are you on? Kernel?
We need all that.
By the way......scores don't really mean anything as It's a cellphone, not a gaming rig but understandable people want to test performance. Do you use your device mostly fire gaming? If so do you get any lagging dieing play now compared to before?

I just got a note 5 from t-mobile today and my antutu benchmark is 41022. Under the Note 4. Im thinking I should take it back. And I did a system restore.
Gonna be fun explaining this at the store.

1.6 GHz max and only using 6 cores...

Hey guys,
i just got my LG G Flex 2 here in germany for christmas and im very happy with it
But there is 1 but important (for me) problem.
It only uses 6 out of 8 cores and the max clock is ONLY 1.6 GHz...
in Antutu im even behind the LG G4 with that "SLOWER HEXACORE" ...
Can someone help me and tell me how to get rid of those 2 problems and get 2 GHz for the Big Cores?
Also, how to easily root my german H955 with Android 5.1.1 ?
Thanks for answers and help
Edit: I got "V15-c-EUR-XX"
Edit2: GPU runs 600 MHz max instead of 650 MHz ...what did they do with my phone
Edit3: I already checked temps, before you ask. 35-40°C max.... i dont think it should throttle at that low temperature.
Okay, now, on the next day it shows up to 1950 MHz for those 4 cores.
Seems to be a temperature problem at only 35 °C ...
Whats the easiest method for rooting the flex 2 (V15-c-EUR-XX) ?
I am not sure if for this phone is the same, but sometimes if u have low battery the kernel switch some core off.
Its normal,sometimes it underclocks the CPU and not always is phone running on 8 cores.... And what about GPU? Well,i have same distribution (DEU) and max is 600 MHz,but currently i have it on 305 MHz. Personally,i never saw higher clock of the GPU,and i own this device for almost month.
Edit: the GPU underclock may be caused by Energy saving mode. However,this has no impact on CPU,CPU-Z shows 1,96 GHz even in Energy saving mode. I had same problems too,CPU-Z showed 1,56 GHz maximum,after restart 1,96 GHz max.
Thanks for the responses. One last question. Why do i get only 60k in Antutu where others get 75k+ without fridge or such?

Well. about an hour ago i ran Antutu test and got 68 000 points. However,it was much worse before (first antutu test had 48 000 points and i was shocked). There are many things that can influence the score. For example-power saving mode,current RAM status (how many apps you got in background),battery percentage and temperature. Maybe best time for test is cold start,when you jump right to Antutu after start (of course not right after,phone needs some time),because you have lowest temperature,highest free RAM and no background apps. If i did such test, i would score more points i think. And last thing-the performance drops significantly when you do many tests in in a row (i mean 1st test and then in about 10 secs other one)

Yeah my performance also seems to increase over time. Weird.
And yes this soc throttles easily. But it doesnt get as hot as my nexus 5 was sometimes with benchmarks and is still faster when throttled. Would not call this processor a fail at all.
Still hoping that the SD820 will be better in thermals though. But this chip is still more than what I need.
How is the battery life when it runs on lower clock speed?
Can someone please use the phone with underclocked cpu (1.6 or 1.8GHz) for some days and post the experience on battery, temperature and phone responsiveness? Thanks.
Battery life is not improved when the phone runs in 1.6 GHz mode. I usually get about 3 h screen on time. The phone heats up a lot under load. I never saw my phone using the full potential with this Snapdragon 810 CPU. It always runs at 1.6 GHz and that seems to be fixed by the ROM on mine.
