Dual core? - Nexus 6 Q&A, Help & Troubleshooting

I watched a YouTube video review of a rom to flash, and the guy mentioned he had a 2 core kernel...
Is there an advantage other that maybe battery consumption as to why you would use a 2 core kernel vice the stock quad core?

not really pretty much the only thing you could expect is worse or same ui performance and the battery savings end up being less than the 50% you'd expect from nixing half your cores. Which is the reason Google decided to just turn all 4 cores on all the time rather than plugging and unplugging them as needed. Minimal battery savings wasn't worth the sluggish ui.

You may not get any battery savings, depending on usage. If you have fewer cores to process tasks, that means that the two that are there would have a higher percentage of run time in a higher power state. If they stay in the high power state longer, you'd end up using more battery rather than less. Using all of the cores allows the system to get to the idle/low power state faster.

Also i believe with all 4 cores running continuously, sharing the work load, it produces less heat as opposed to having only 2 cores running mostly at a higher state which would keep the phone warm most of the time.

Well I was just curious. It was a video review of pure nexus and he briefly mentioned that he had the dual core kernel flashed but he didn't elaborate, so I figured I'd ask.

[Q] which to choose 1500 mAh / 1750 mAh battery for Ace??

I have Samsung Galaxy ace overall this phone is really good ..but it lacks only in Battery backup .For watching movies ,listening to Music the default 1350 mAh battery works fine but as soon as i start using internet with 3g connection battery lasts only for 4-5 hrs ..so i wanted to know does 1500 mAh /1750 mAh battery works properly in Ace without any problems and how much battery backup i will get with it??

K bt wat abt the backup ... for how many hrs ur battery lasts if u watch- 2 youtube videos ,surf net for 1 hr in a day,and download 2apps from market with 3g connection???
And tell me whether Li-on
1500 mAh battery functions properly in
samsung galaxy ace S5830..
I mean are there any problems reported
like cell not functioning properly,or cell
phone getting overheated...if any plzzz let me know!!
Alphatime like they are not the same. You really can't fit i5800 battery into galaxy ace. Why would you claim such a thing?
Now for some useful information. The phone can be optimized to last long in standby mode, simply by turning off the data connection when not using it, and switching to 2G. You can let jucedefender do that for you, or APN access point to manualy turn connection on and off.
But what good is a smart phone in a standby mode? The moment you start using it for something like say playing games, you got 2 hours gaming on a full charge. Now that’s pathetic.
Here are some things you can do to keep CPU less busy.
Use bsplayer lite to watch movies. It uses hardware acceleration to decode videos. It will keep CPU consuming less than 150mW. Unlike other players that use software decoding and constantly hit cpu usage as high as 400mW. So you can get 5+ hours (depending on brightness settings) watching movies using bsplayer.
Generally browsers will remain under 150mW if you let them sit still, but the moment you start scrolling (CPU) or opening links (radio) the power consumption will peak. Now Opera mini seems to take least CPU power. Obviously turning on wifi and 3G will drain much faster. The best battery time can be achieved using the 2G network data connection together with opera mini. Opera mobile seems to have hardware acceleration but I yet have to test the power consumption.
Test the applications you frequently use. You can use the power tutor program to monitor power consumption and test your application.
I've found that some programs, even the simple book readers will just lock the CPU at 800MHz even if you let them stand still, doing nothing with constant 400mW drain. Uninstall such applications or use them for short periods.
Well games have a high CPU demand and subsequently power consumption, and there is nothing to do about that.
Basically you can get:
2-3 days in standby or,
2 hours of playing games, and using unoptimized applications or,
5+ hours using applications with good coding and or hardware acceleration.
Underclocking the CPU using setCPU has no effect, becouse optimized applications allready scale the cpu to 250mhz or 128mhz. And demanding applications will stutter when underclocked and won't consume much less power.
I've just ordered this 2430mah

hey thnks for info...jst tell me whether Li-on 1500 mAh battery functions properly in samsung galaxy ace S5830..
I mean are there any problems reported like cell not functioning properly,or cell phone getting heated...if any plzzz let me know!!
All the measurements that ive made were done using official 1350 mah battery.
So using oem 1350 battery on a single charge you can get 5 hours of video using bsplayer or 4h using opera mini with wifi. I just dont play games on my samsung or use unoptimized applications and I get good battery life.
Currently there are no >1350mah batteries that can fit inside galaxy ace (S830). All these unofficial batteries that claim more capacity are a hoax (chinese 2400 really?).
If there will ever be a larger capacity battery, they will be sold together with a special back cover so that a much thicker battery can fit inside the samsung galaxy ace.
Cheers

Yes, that's it, same as my experience.
This particular gold 2430 battery, has a faulty or missing temperature sensor. This means it can charge to a somewhat higher capacity, but never actually 2430mah.
The capacity of 2430mah would mean an energy density of 900W/L. Now currently the record breaking panasonic lithium ion battery has a denisty of 650W/L
The good thing about a temperature sensor is that its actually a failsafe mechanism keeping the battery from not exploding.
So try to keep your phone on a cold place while charging and away from flamable stuff.
And even if its made in Japan I somehow suspect that the Chinese have to do something with the faulty temperature senzor.
Cheers.
Well My ace doesn't get very hot anyway so I'm not worried

Nexus 4 throttle

http://www.youtube.com/watch?feature=player_embedded&v=koLJ4BU9tgc
Swedroids test
It throttles at 36 C and shuts down at 59 to 60 C.
They should increase the throttle to 45 C and when 45 C is reached make the throttle more aggressive would be a better solution.
What do you guys think?

If it gets to hot people get the yellowing... I would rather run cooler and not worry about it.
Is this throttling effecting real world usage or just benchmarks? Not being sarcastic, asking a question.

Well i dont know, i dont care about benchmarks, just thought about informing what i found.
And increasing the throttle level and making it more aggressive later on was just my opinion.
I would like to see a comparison with the iPhone 5 and Galaxy S III on what temperatures they shut down.

I think that the video was pretty painful to watch! lol WHO on earth would run a phone to death like that?? Hope they have an extended warranty... For real though, I would like to see them bump up the throttling temp a lil but in the real world most users will NEVER experience something like that because that app is meant to run your phone into the ground! I hate that they even make benchmarking apps cause it makes me competitive but I have found that the N4 is FAST as hell so I don't need anything else to prove that to me... Good vid though for the info but lets all step back into reality...
I'm thinking the S4Pro is rated to a higher temperature, and the thermal shutdown is really more for battery health than processor health... Regardless, 11 minutes at 100% load with no real cooling system...
Does the Galaxy S3 also shut down at the same temperature?
12 minutes with the CPU pegged at 100% on all cores with no cooling is impressive, IMHO. Yes it clocked down to 1150MHz but that's plenty fine.
No real world task will come close to pushing the processor that far. I doubt even gaming will task the cores so much that the phone throttles them back.
A lot of modern laptops won't run 12 minutes of solid prime95 before clocking down. This c2d 2.8GHz laptop I'm typing on now will clock down to 800MHz after 15-20 minutes of prime95...but it doesn't throttle at all when doing real world stuff, even compiling or encoding etc.

In my opinion the throttle should engage at 43-45c because at 36c its idle temperatures when the phone i just on stand by.
Ok I fear that's a real problem. What if I want to play a graphic intensive game for a few hours? Expecially on a hot summer day?

So much for Qualcomm's butter test
In the video description you can find:
"The reason as to why we published this video is because we've never experienced temperatures reaching ~60 degrees C before, nor have we ever experienced a phone shutting itself down after just 12 minutes of continuous full load, nor have we ever experienced such aggressive thermal throttling. It pretty much throttles down instantaneously from 1.5GHz to 1.2 or 1.1GHz during heavy load.
All temperature readings are presented in Celcius.
The Nexus 4 seems to have some issues with heat development. At least if we are to believe our findings. There might of course be a possibility that our unit is faulty. We are however not alone according to the Google Android issue tracker: https://play.google.com/store/apps/details?id=com.into.stability&feature=.... A google search on the matter will also render lots of user reports concerning heat issues.
In comparison the quad core Galaxy S3 (3G) battery sensor reports ~41 degrees after 13 minutes of full load with the screen set to 100% brightness. It does however lower the CPU frequency to 800MHz at times, but mostly run at 1.4GHz. Our IR meter reports about ~34 degrees if we go ahead and measure the hottest spot on the back of the phone (area around the camera lens)."
For me, this is a no-go. I wouldn't buy a phone that shuts down after a few minutes of processor stress testing. Can somebody tell if the same happens with his N4?

Thing is that if you search the web for this problem, you get a lot of hits about people have thermal issues. I hope it just is a defective unit but it seems it is not the case. The S4 pro seems to be generating to much heat and requires too much power. That's why it empty's the 2100 mha battery a bit faster compared to other devices.
Maybe the S4 pro is more suitable for tablets and not phones.

Very few applications will use 4 cores. Hell, most don't even use 2 cores by default. So the chances of you maxing out all 4 cores in routine usage isn't very likely. The extra cores typically benefit smartphones when one process is utilizing a core already, a different process just gets thrown over to a different core so it doesn't have to wait for CPU cycles. Most smartphone use is "burst-y" so this helps end-users out quite a bit.
99.9 % its not the S4 Pro`s fault, just the lame battery from LG. I mean WTF after 15 secs it clocks down !!!!
Yeah, thats weird. But I could live with it, expecially when the phone runs buttersmooth. But if the phone shuts down after a few minutes of processor intensive tasks that's a big problem. I know that barely any app is using 4 cores simultanously, but what happens if you stress-test only one core? Does the phone also shut down?
This doesnt seem that bad, you're stressing it pretty hard which wont ever be done in real word conditions, for example take intel burn test, most people find this stresses the chip to temperatures 15C+ over any possible real word tests/usage.
You say the SGS3 throttles to 800Mhz at some points well thats pretty poor is it not? Clock for clock the s4 pro is superior and so clocking in over 300Mhz faster when throttled its pretty good id say. If you're comparing the S4 vs the S4 pro (US SGS3) then its pretty hard to say the battery sucks when its got more power! Of course it will run hotter haha.
I think they could put back the throttling limits a bit though, I think it maybe a battery issue more than anything though so maybe its a fault... Please test it by stressing a high end game for an hour or so tracking the temps and clock speed, that would be a much better indication.
edit: Seen your reply before me, It wont shut down like that in the real world! If you stress test only one core I can assure you that it will run MUCH cooler, you are essentially testing 2x the amount in the s4 Pro than you are in the dual core varient, in these stress tests it works pretty much 110% each core, in the realworld there will be idle times and switching between cores handling different threads, lots of variences that should mean it would be ALOT cooler all the time even if using all 4.

1 core likely won't generate as much heat, and not to mention the whole point of the cores is to distribute load and operate at max efficiency rather than less cores at max.
I understand that some people have issue with the throttling, but until people report that they can't play x and y after z minutes it is a non issue. It may have to do with the glass, maybe LG battery. It is possible the throttle is there to preserve the higher recharge cycles LG Chem batteries have.
Unless it actually ruins an app experience, on stock rom and kernel, it is not an issue. If someone would rather pay 400 more to boost their bench by 5% that's up to them.

Mhmm, I guess it won't be a problem in real world usage. Nevertheless it's quite weird that the phone heats up that much AND THEN SHUTS DOWN, expecially in comparison to other phones like the SGS3, where this problem doesn't occur.
But yes, I didn't hear any complaints about critical-heat-shutdowns in real world usage, so maybe I'm just overreacting. But at the moment it's winter in USA and Europe, so let's see how the phone performs in summer heat
My old HTC Desire often overheats and shuts down on hot summer days when I'm using GPS or playing games, so I just hope my next phone won't have this problem

Mine has been shutting down due to overheating at least once a day. I've just exchanged it so will see how that is.
Worryingly, I will often be doing nothing other than web browsing or similar which should not stress the CPU

Stability test v2.7 App- Share your result

Hello,
I just got my nex4 few days ago. I would to know how your nexus 4 final stability test result.
Application: Stability test v2.7
Conditions: classic stability test with:
1. Everything enabled, wifi, 3g, etc.
2. Full brightness
3. 18minutes run
Result:
1. Battery temperature
2. Battery % drop.
Here is mine: 30% battery drop, final battery temperature of 52degC. If my result is peculiar, then I shall ask for a replacement. Its very hot, and the battery drained too much.
No worries if you have customized kernel or rom. Mine is everything stock.
That's normal. You ran it for almost 20 mins. If all four cores are running at highest frequency then the phone will get hot, and therefore the battery temp will go high. Unfortunately Nexus 4 is prone to get hot and therefore it throttles down. Use custom kernel to get more out of your phone.

To be more accurate, each user is different. The phones are identical.
Power Saver mode will not save you any remarkable amount of battery unless you are maxing out the CPU or GPU (like playing games). Since what it does under the cover (besides what it advertises in the options) is downclock the CPU, this can actually be a detriment to battery life. It is better for battery life for the CPU to run at max speed for very short periods, and then go to sleep. It uses more power by running slower (and thus staying awake longer).
Again, it'll take a lot to really notice a change in either direction, though.

Correct me if I'm wrong, but the jury's still very much out on race-to-finish style processor governors. Sometimes they do well, sometimes they do badly. Either way, it depends on use case.
I would also hazard that it's very much an oversimplification to say that the phones are "identical." It's hardly unheard of for different production batches to use slightly different components. However, the impact from this is probably negligible compared to variations in user habit (and if it's not, then someone in QC/QA needs to go).

Race-to-finish is pretty much the de-facto standard for every decent mobile device right now. It's even getting pushed onto laptops and their associated CPUs (like Haswell).
And I don't think it's an oversimplification if the differing components are only ones that are using on the order of micro-amps of power. They're not using different spec CPUs or something. That would be insanity.
Thanks Vincent for specifying that for me, I guess it's only roms because I have heard that each phone acts different. But this is new to me the phone uses more battery when it's at low speeds? I usually underclock to save battery while screen on as well as during sleep.

When your phone is asleep, underclocking does nothing, because it's not really even running at all. This mostly applies when the screen is on as well, for any cores not active. 0mhz > any underclock you can manage

Moto G6 v.s Redmi note 5 pro. Which one should I buy for the long run(approx 4 year)?

Hello guys...I am new to the community but I greatly admire the work you guys do
Hope my confusion will be solved.
Neither. If you are really looking for long run you should buy Moto e4 plus (80 odd usd) or Moto e5 plus (180 odd usd). Each charge of battery lasts for 3-4 days in these phones. That means every year you'd be charging the phone approximately 100 times. Phone battery goes down to 50% by 500 chraging cycle. And the battery capacity severely affects cpu performances. Plus these phones would never get any updates and the performances would not change in terms of operating system. As apps evolve and demand more RAM, the phone would feel increasingly slower. But given 3GB ram on E5 plus and expandable storage, and 5G LTE coming soon (full rollout by 2020), you'd feel better to get rid of the 180 usd phone after 2-2.5 years of usage. (I use a Boost Moto G6 play myself for media consumption (80 usd) with an iPhone 6s plus (4 year old now - did a 29 usd battery change) as the daily driver, this is an unbiased "opinion").
I mean this with all due respect and reverence to SB581240. And I write this from a strictly pragmatic and realistic point of view.
I would suspect that battery life plays a factor in most smartphone purchases. I would also guess that probably less than 10% of all smartphone buyers, would rank battery life as the single most important feature. I'm going to assume that the OP is considering the phone's as a whole, and not how often he has to charge it in a given year. So with those ideas mentioned, allow me to introduce the likely facts...
Lets start with the battery idea, just for grins. This is regarding the previous post and the recommendation of the E5 Plus. Anything after that will be strictly dealing with the Redmi vs Moto G6, as thats what the subject of the OP deals with.
The Redmi Note 5 Pro has a 4000ma battery, compared to the e5 plus 5000ma. Yes, the e5 has approximately 25% more 'juice'. While this is true, it doesn't tell the whole story. 1)The Snapdragon 636 in the Redmi is built on a much more modern and extremely more efficient 14nm process. The MUCH Older E5's platform is based upon a Snapdragon 425 and its 28nm process. Remember, this processor was first available in the summer of 2016. The Redmi's 14nm process 636 was introduce just last fall. Physics and real-world testing show that the 14nm process is approximately 35% more efficient. To put that in perspective -- think about it like this. If all things were equal between the two phones, except for the 14/28nm processes.... the Redmi would last approximately 35% longer on a charge. So simply adding a 25% larger battery, would not bridge the difference. The Redmi would still win by around 10% in single charge life expectancy. We must also take into consideration the type of charging that is offered. The Redmi wins out in a landslide... using today's Quick Charge 4.0, while the E5 uses the largely outdated 2.0. The difference in staggering. The 4.0 will give an approx 50% charge (from 0%) in about 5 minutes. The 2.0 will take around 30-45 minutes to do the same. Last thing I'll say about the battery... the Redmi, as I've pointed out, has a 4000mah. The G6 has just a 3000mah. A full 33% more juice with the Redmi.
Now lets get down to the facts that most of us care about between the Note 5 Pro and the G6:
CPU: The snapdragon 636 vs 450. The 636 wins in a landslide. Both are on 14nm dies. But the 636 is on a whole other level. Geekbench single core performance is approximately 90% higher (roughly double). 1385 vs 750. Multi-Core performance is 4700 vs 3800. Both use 8 cores, but the Redmi uses Big/Little styles with 4x cores being A72's compared to the G6 using A53's. This is where the single core performance just blows it away.
RAM: Again, the Redmi is lightyears ahead here. It has 50% MORE RAM than the G6. Further, the G6 uses a slower and somewhat outdated DDR3 ram @ 933mhz, while the Redmi uses the modern DDR4 @ 1333mhz. Recall, Swap, and ZRAM are vastly improved because of this.
I could go line by line highlighting the differences and the advantages of going with the Redmi 5 Pro... There's really no comparison. Today, and definitely 'tomorrow'.. the Redmi is the way to go.
I love my Motorola G6 Play. Its a nice mid-level budget phone. It does everything I want and need it to do. Mine is rooted, and I use kernel auditor, along with L-Speed scripts. I have improved my between charge times from about 30 hours up to a current best of 52 hours. I use a custom conservative governor that I modded the tuneables for unbelievable responsiveness and quick factoring down. I also use an alternative GPU governor. On top of this, L-Speed allows me to use aggressive doze, and several battery related tweaks... and literally puts the phone into "Deep Sleep" seconds after the screen turns off... using next to nothing in power as long as its in this state. 8-9 hours of screen off time at night consumes 1% of the battery. And by using Kernel Auditor, I have 3 profiles saved. 1)the conservative tune for battery life. 2)a multitasking tune for heavier use of resources when doing multiple tasks. 3)a gaming profile for locked in 1401mhz/650mhz cpu/gpu, LMK tweaks, entropy adjustments, and heavy I/O tweaks.
This phone is optimized in every way that is currently available, and for any form of use that I can come up with. So no complaints.
FYI, I'll be starting a thread in the coming days listing the different profiles I've mentioned here so that others may double their battery life, or increase their performance by 10-15% if they so choose.
Thanks for reading!
There is a long response above, which I believe is informative (because I have no clue). Just for a reference, 5G is coming really soon, so strap on your chest belts, your phones with all its 8GB RAM, 1TB ROM, 4-5-6 clusters of cameras are going to be dumpster-ready soon.
Now, just for a quick reference: iPhone X has 3GB RAM, it has the best-in-class AMOLED display which is a drag on RAM but nevertheless 3GB. A11 Bionic is faster than any Snapdragon (including 845). So that's that. Fastest processor, best display, 3GB RAM.
I know we are on XDA and all these RAM processor battery entropy adjustments LMK tweaks are really important and so on. But as I have a limited perspective on these things, if I am buying a phone today, the only feature I'd be interested in is the price. Why? All phones will be dumpster-ready by 2019.
