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.
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.

I am looking to buy a tablet I come across 2 tablets which have intrigued me the xperia z3 compact and the nvidia shield k1. I liked them both for the specs and low price. The tablet will be used for surfing the internet, youtube, Facebook, games, watching movies things like that so I was wondering if someone who has both or has had experience can recommend me which one is better or if there is another tablet that is better suited for me.

I bought the Shield yesterday because I want to play games with.
But If I was not in this situation (more video/internet/app usage) I will definitively go for the Sony because despite the smaller battery she has better battery life and not a little it's like 10 hrs more in certain condition so very well optimized rom from sony.
But maybe I can fix the shield battery with a custom rom will see
The z3's bottleneck is the GPU.

If you set the Shield power mode to just 2 CPU cores, you'll get much more battery life.

No problem for watching video and stuff or it start lagging?
It still runs smooth. You may sense a difference with highly demanding games. Or when you transcode videos.

You cannot disable cores on the k1. You can verify this with cpuz. Also the z3 compact tablet has a terrible processor combo by today's standards and doesn't come anywhere near the k1. It also does not have nvidia specific games, console mode, or gamestream (although this can be done with a 3rd party app call moonlight streaming). The speakers are also not as good and it will probably never get another update, ever. There is no reason to buy the sony tablet over the shield.

Then cpuz is apparently showing wrong data, I'd say.
Plenty apps have compatibility issues with a myriad of Android devices.

Unfortunately cpuz is accurate and you cannot disable any cores on the shield tablet, despite what the UI might be telling you.

Ill run antutu for you right now, 2 and then 4 cores, and post the results. I assure you the cores will all be active no matter what. They are always firing no matter what you do.
The benchmarks do indicate that there is a performance hit, surprisingly. I ran a total of 8 benchmarks to be sure. I am not sure exactly what is happening, but the cores are not being turned off, that's for sure. You can verify this with any CPU monitoring app, I tried 5 different ones and they all said the same thing. I think maybe when you force the CPU into 2 core mode, it may under clock two of the cores or something, but not disable them. It's helpful to know that the option at least does something and is not just there and fake lol. However like I mentioned in another post of mine, setting the performance mode to custom to enable only two cores, will perform worse for battery like than just using optimized. Forcing two cores for individual games, might be helpful however, but probably not by much. As you can see from the following benchmarks, the scores are not halved by disabling half the cores, they are only slightly reduced. Not exactly sure what's going on, but may look into it further in the near future.
Benchmark 1 - two cores enabled:
CPU: 18378
Benchmark 2 - two cores enabled:
CPU: 18374
Benchmark 3 - four cores enabled:
CPU: 22660
Benchmark 4 - four cores enabled:
CPU: 22409

Under what kind of conditions would that be? Engadget's review says 13.5 to 14 hours for their continuous video loop test, and they estimate 10 hours in "real world" use conditions.
https://www.engadget.com/2015/01/11/sony-xperia-z3-tablet-compact-review/
I get around 7 hours of screen-on time with my Shield, running stock and not messing with the cores.
The Sony tablet's battery life is impressive, for sure. But to say a 10 hour difference, is probably an overstatement.
This thread makes me wonder (yet again) where are the tablets? I know the tablet market is pretty stagnant, but its still a bit ridiculous that we are sitting here comparing a tablet from 2015 versus one from 2014. NVIDIA shelved its plan to update the Shield tablet this year. Not much else on the market. On the higher end, Samsung neglected to update its Galaxy Tab S2 this year.

So under what circumstances will you switch to 2 core mode to save battery? The tablet has great battery until it fires up a game and there's not much you're going to do about gaming battery life.

Switching over to 2 cores during a movie will likely cost you battery due to the fact that the minimum clock speed for custom is much higher than the minimum clock speed for optimized.
Hi,
Need some advice here. Two phones for sale, both same brand/model however two separate specs and I need the one that will draw the least battery as I use the phones screen time for 8 straight hours a day (satnav) so the less battery draw the better. I do not care about anything else!
1) Snapdragon 625 - 14nm but 5.5" 1080p Screen
2) Snapdragon 435 - 28nm But 5.0" 720p Screen.
So the first phone has the newer 14nm CPU however has a bigger screen area (5.5") and Full HD.
However the second phone has a smaller screen area at 5.0" and is running less resolution @ 720 but has the older 28nm CPU which draws more power.
So which setup, in theory, would use less power?

It comes down to usage I suppose. If the task at hand requires a lot of processing power but is less taxing on the screen/GPU then the SD 625 is better. If its the other way around then choose the device with the SD 435.
What about battery capacity, are those the same as well?

Yup both phones have the same battery capacity, they are both identical in most respects, one is the note version the other is not.
The usage is 100% satnav (Waze) no other apps will be running. Any ideas on the usage of Waze?

I'd go for the newer/more efficient 625. As things such as GPS, Mobile Data and WiFi usage are embedded in the SoC. Screen brightness and density can be easily be adjusted to reduce power consumption. And you can also underclock the CPU (or turn on some sort of power saver mode) to squeeze out as much juice out of the battery as possible. The difference between a 720p and 1080 p device isn't that much anyway. But the improvements of the 625 over the 435 is far greater.

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!

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
