(Experts please!)How does elixir work?

I sorta want an answer from anyone who knows about Android architecture... elixir is an app that reports different specs in real time. I.e: cpu temp or ram usage. (For those that didn't know). I showed a friend and he says this stuff is kinda fishy since it can only focus on one core at a time, is it giving false info on dual core phones? How does it obtain info on the CPU temp too? I don't know what to do since I like using it and he just told me its a piece of crap...

Well without seeing the apps code, you can't really tell how the app works.
I also don't understand what your friend means by "it can only focus on one core at a time". What does that have to do with reading out ram usage or temperatures?
The cpu temperature is somtimes not the real cpu temp, but the battery temp. Not all devices have temperature sensors on/in the cpu.

haha the elixir is samsung galaxy SII the battery life is very very good thanks samsung ^^

Dual core phones have two threads of data that they churn out and apparently its impossible for the app to read both simultaneously.

Cpu Usage and Ram is probably read from files like '/proc/stat'.
I'm still confused about what your problem is with dual core devices.

Heating issue explained (sorta)

So there are lot of questions about people asking if this heats up or not mostly by people who want to buy this phone nywas there answer is "YES" it heats but its like only the tip of the iceberg i have used lot of mid range and some high end phones before and believe me every phone heats now and then depends on the tasks you perform so is this with this phone but main reason this phone heats up are
1. Snapdragon 615 the 8 core processor is a beast in snapdragon 600 series but with great power comes great responsibility running 8 cores simply means a lot of work so yes if ur playing a game or something that actually uses 8 cores the phone will heat up more compared to a 4 core processor(do the math).
2.Compact motherboard you have to understand that the phone is remarkably slim and compact.
The above are the two main reasons due to which this phone might be getting a little warm. But that doesnt mean this is only phone in the world that heats up the above mentioned are only reasons for this phone
My experience with the phone..
Yes it get got hot during games but believe me it didnt surprise me because the other phones i have used got hot too. And when i say hot i dont mean hot as in a freshly baked cake hot but you can tell its hot (kinda hot)

Edit
1 2

Nd have a nice day

1st point is BS

FYI its not a true octa core phone which means that all the 8 cores never simultaneously work together. The processor is a combination of 4 low power cores for balanced performance and four high power cores for gaming and intensive tasks. They switch as and when required. So your "math" is complete bull ****. However everything else is sane and meaningful. It will be a pity if you bought the phone thinking that the 8 cores work together considering the fact that there exists true Octa core phones in which all the 8 cores really work together.

So you just mean to say that all other phones with this processor heats so that gives Xiaomi a lame excuse for heating.
If they are aware of the extreme heating problems of the processor, why to launch such a lowly device in the first place.
One should not blame and compare other devices just because you are incapable of producing a good phone.
Shameful act by Xiaomi.

You are absolutely right, it is established that all 8 cores can be used together, however I am still researching on the fact that how much do we gain on performance by using both the low and high performance cores together (at least for benchmarks and tests). The tools which I am using for benchmarks have a lower resolution rate than the amount of time a core reports to complete a thread and thus the delay.
However apologies for the wrong info, thanks for noticing and correcting.

current firmware (V 6.5.5) has options for change max.freq. for cores ?
Or only switch between "high perf." and "balanced" modes ?

No manual frequency modes as of yet. Just the in-built PERFORMANCE & INTERACTIVE governor modes. I guess we are all waiting for root.

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.

Root cause of Yuphoria's heating problem, not discussed anywhere

Hi, If you use yuphoria in a non-ac environment in India in summer where outside temperature is easily between 35-40 degree Celsius, your ear and nearby head area start hurting. Its a very dangerous, as it can cause permanent damage to ears or head.
Now before anyone say, common its a smartphone, it will heat up in such temperature, its normal, I would like to inform you, when I use my father's moto E3 power in same environment I don't feel any heat.
So obviously there is some problem with Yuphoria. consider this, your phone is sitting ideal from past one hours, a call comes, you pic the call, talk for 15 minutes and then you can feel that the screen is warm in the top right corner. you are not playing any game, doing nothing which involves heavy cpu processing, you are just taking a call for 15 minutes.
You should not feel any discomfort by doing this if mobile is Ok, as proved by moto E3 power. So something is seriously wrong with yuphoria.
So I tried to search the net to know the reason why yuphoria is overheating and came across useless advice, like stop the running processes , use different charger etc (I mean basic stuffs), but my question was still unanswered , why motoE3 power is cool even if other apps are running and yuphoria is not.
In my experiment I came across one very interesting observation which is not discussed anywhere, so here I am presenting the real cause of yuphoria's heating problem.
If we see the cpu usage using CPU-Z app in moto E3 power when no other application is running, we can find that its 201 MHz for single core most of the time. This I have checked in moto E3 power having stock ROM and data connection off. I am attaching here screenshot.
https://ibb.co/ddCmLF
If we do the same thing with Yuphoria , it never goes below 800 MHz. here are the screenshots of Yuphoria CPU usage and governors selected
https://ibb.co/bUJyZa
here is the governors
https://ibb.co/iCJXua
So obviously Yupohria CPU is always running at higher frequency than Moto E3power .
FURTHER MOTO E3 POWER HAS METAL PLATS ATTACHED TO PROCESSOR TO ACT AS HEAT SINK. you can check out the disassembling video of yuphoria and moto e3 power on youtube to see that moto e3 power has heat sink whereas yuphoria doesn't have it.
Moto E3 power is using mediatek processor which produces less heat and also the highest frequency of Moto E3 Power is less, still they included a heat sink in moto e3 power.
yuphoria is using more heat producing snapdragon 410 processor, still the engineers have not included heat sink. why yuphoria ? why?
I experimented by setting minimum cpu frequncy to 200 MHz and using powersave governor and found that now I can take calls without any heating issue. Remember still in this case yuphoria is using 3 cores with 200 Mhz frequency where as moto e3 power is using only one core with 201 MHz.
now I understand that moto E3 power is running on stock and my yuphoria is running on RR Rom, but I used to feel same heating problem even when my mobile was on original cyanogen ROM, so I think this problem of processor not going below 800 MHz is present even in original cyanogen ROM of yuphoria.
Now I want to know from all the technical experts here, why yuphoria's cpu is not going below 800 Mhz even when no other app is running. Is it the limitation of snapdragon 410 processor and nothing can be done about it, or it depends upon kernel and flashing another kernel or ROM will solve the issue.
obviously we don't want to use powersave governor with 200 MHz setting, otherwise what's the point of buying a 1.21 Ghz processor mobile. We want it to use minimum frequency that 200 single core when no other application is running and using higher frequency only when required like moto E3 power.
Is it possible? If yes , how?
I am also curious to know why they decided to not include heat sink in yuphoria?

I am not a technical expert but i don't think 800mhz might be a limitation of snapdragon 410.
Plus with ur experiment results i think it might be actually software flaw and with custom kernel or a custom rom which gives the ability to choose min and max speeds should fix it as u can choose min to 200mhz even with other governors.

what are those ,,other users"? I think only 5% of the Exynos owners won this lottery. I mean, this is a failed chipset and Sammy doesn't want to recognize this, or at least give us the ability to purchase a Snapdragon version.

35 is not high, to my mind. Around 39 i tend to notice it. But it rarely happens to go that high, usually around 36/37. Maybe if I'm charging and playing it will go high

When Samsung developed the Exynos 2200 it was supposed to power the central core clockspeed at 1.9GHz. After they finalized development (or possibly before they finalized development) they discovered any speed over 1.34 GHz generated unacceptable overheating. Instead of re-engineering the SoC they decide to throttle the crap out of it. In the meantime they've been tampering with the other cores in an attempt to find an acceptable balance. I would submit to date those efforts have failed. Welcome to the wonderful world of Exynos!

make factory reset and dont install anything - is it still heating?
disable cellular overnight - is it still heating?
enable cellular, but disable data & wifi - is it still heating?

And I don't understand why people are still buying devices with Exynos from Samsung..Only because it's a Samsung? Don't get me wrong, I would go instantly to Huawei if they would have again GMS, because I really loved my P30 Pro, but without GMS my only alternative it's Samsung since other brands are having a lot of things that annoy me.

Welcome to Exynos !
btw, 35 isn't high. my a3 usually heats up at 40-60 (when playing games) and also has an exynos processor (Exynos 7580)

Get Good Guardians and install Thermal Guardian.
It will let you change the thermal profile, like if you are in a hot day or cold place. Also logs all the apps that might warm your device, then you can turn problem apps off or set more battery savings aka less power, aka less temp.

i found when converting .vob to .mp4 on the device it gets very hot, but of course that is quite an intensive task, i would be interested to know how a snapdragon version handles that

Snapdragon!! Very useful to Cook egs, with exynos in the last ten years and for note (with s22) never seen a minimal rise in temperature
