You are WRONG about that. It's not a gimmick. You are sorely ignorant about science and believed Master Liar Steve Jobs.

That was a Steve Jobs MARKETING LIE -- that anything over approximately 300 dpi was too fine for the human eye to see. It's been repeated ad nauseum and it's a LIE. Jobs had a smartphone display to sell with a shade ove 300 dpi and so he concocted this story to sell his phone.

All the slobbering tech journalists never questioned it, except for Wired magazine who had the balls to contact an optics research scientist. The optics expert said it's actually 477dpi -- NOT 300 dpi for the "Retina" crap Jobs was describing.

477 dpi -- close to 500 dpi -- are we there yet? Our Nexus 5 @ 445 dpi is a LOT closer than the iPhone's 326 dpi. :D

It's not dumb. I work in HDTV and I appreciate the higher resolution on this Nexus 5 display. Yes, I can see a difference between the 720p of my Galaxy Nexus and the 1080p of this screen. You don't want it, then don't buy it. Go get a crappy Moto X.
[Nexus 5 Original Android Development] Wenzo2:
ok! just for information

for change screen resolution:

su

wm size (for example 768x1366)

wm density (for example 316)

note: after that the screen is deformed. do a reboot and the screen return to normal.

with this settings i've got a increase of performance.

asphalt 8 (768x1366)

avg:35 frs

max:42 frs

min:32 frs

asphat 8 full hd

avg: 30 frs

max: 36 frs

min: 18 frs
[Nexus 5 Original Android Development] Wenzo2:
much more important the quality of the display. maybe the human eye can notice it but I can not find differences. for me both are great resolutions 330 and 445. (for example according to the studies we may note the frs to 60frs but the difference is minimal with 50-55 frs.)

you can see the difference with GNEX because it is poor quality AMOLED (see RGBG PenTile)...

Hi all , I get random time changes , like it's 10 pm a second and 5 am at the next one ! Can that be a kernel related thing ? I'm on r15 + stock ROM
[Nexus 5 Original Android Development] magnamentis:
what has this to do with the kernel ?

just don't get it, was reading for minutes and found only few posts kernel related but a lot of display stuff, did i miss something or is all that totally OT ?
[Nexus 5 Original Android Development] i860:
Hi Franco!

Did 30m dead trigger 2 and 20m beach buggy and no lag what so ever. Just one thing the back of phone is getting quite hot. Will test tomorrow the battery life after a full charge.
[Nexus 5 Original Android Development] ChazzMatt:
Yeah, it's off topic but you can't let the people who claim anything over 300 dpi is useless to continue to spread their misinformation -- repeatedly in this thread. Steve Jobs started it to sell his iPhone and now even Android owners seem to believe it. It's close to 500 dpi, not 300 dpi and I cited proof.

Now we go back to discussing kernel. :)
[Nexus 5 Original Android Development] shaker2k:
This is a kernel thread?

:eek::p
[Nexus 5 Original Android Development] Savant:
On another note latest r15 having no problems with it and no reboots or anything odd. The kernel does exactly what I want balance performance/ battery and Franco knows how to work his magic. Last night I had 1% drain over 8 hours when the screen was off .
[Nexus 5 Original Android Development] mag01:
1% in 8hours? How do you achieve that? I barely reach half of that even with conservative cpu governor setup and approx -50 mV undervolting.
[Nexus 5 Original Android Development] MrGriffdude:
Anyone having issues switching to Art on cataclysm?
[Nexus 5 Original Android Development] magnamentis:
more on battery life

sinde the thread is full of battery life posts i just wanted to mention

that i'm using juice defender on all of my devices and get the following results:

- Nexus 5 _ 2% in 7 hours during the night all sync, location functions and radios on 1 email account to sync, lightflow on and identically set up

- Nexus 4 _ 5% in 7 hours during the night all sync, location functions and radios on 1 email account to sync, lightflow on and identically set up

- N7100 '__ 3% in 7 hours during the night all sync, location functions and radios on 4 email accounts to sync, lightflow on and identically set up

- I9100 ___ 5% in 7 hours during the night all sync, location functions and radios on 1 email account to sync, lightflow on with sound only set up

rom and kernel configuration you find in my signature, all devices with original battery and as far as

the roms allow identically configured, same apps, same settings cross platform as far as possible.

to give an even better idea what these number mean, the Nexus 5 on Cataclysm with stock kernel

was on 3% in 7 hours during night hours ( cataclysm uses 100% stock kernel )
[Nexus 5 Original Android Development] Testraindrop:
You can't have a cool device and huge FPS number all the time, there are physics in play :p

But if its to hot for you you can change the throttling temperature to something lower in FKU, but then you might see lower FPS in games...

Wrong thread. ART has nothing to do with the Kernel.
[Nexus 5 Original Android Development] MrGriffdude:
Not wrong thread.. just checking to see if it affected it.
[Nexus 5 Original Android Development] misterviolinguy:
I'm currently using the latest cataclysm release with ART, franco.Kernel r14. No issues whatsoever, and noticeably faster than Dalvik.
[Nexus 5 Original Android Development] bleuxeon:
There is a common mistake regarding battery consumption measurements : charging it during hours while it allready at 100% then unplug it than go to sleep then report.

What your stats then say is biased because 100% does not realy means it fully charged but it can be fully charged too... so that 's confusing.

If you want to check how many % you have lost during a night then start it @ 90% or 80%, anything but no 100%.

I bet you would have very differents results, and so very different conclusions.
[Nexus 5 Original Android Development] locke84:
Wow.. r15 looks promising, made me want to test it too.. Will flash the boot image today, hope I can contribute something with my test
[Nexus 5 Original Android Development] magnamentis:
not really

the only thing where you are right is that 100% is not equal to 100% as in fully charges, it could as well be 99.5% but:

your conclusion that it's better to start at 90% or 80% is not correct because the same applies, when the indicator

shows 90% it could be 98.5+% or 99.4-% thus the possibility for a different starting point is not 0.5% like with 100% but even1 full percent thus twice a large.

further if someone likes to wait ever day for a certain value and/or remember the last value before going to bed, his problem, i prefer

the easy number 100 as a starting point which, by the way, allows me to disconnect the charger after use being right at it.

last but not least the discharge of batteries is not linear, means the discharge indicator start often slow and accelerates towards

the end of a battery cycle. this means that if you start today at 90% to measure and tomorrow at 80 or 70% you will again not get

accurate and comparable values.

so all this is in vain, the easiest an most reliable way to go is to disconnect at 100% and check the next morning what happend to the accu over night :)
[Nexus 5 Original Android Development] mag01:
[MENTION=4459653]bleuxeon[/MENTION]

Yes I know, that's how I check it myself and that's what I'd like to know from those who report such insanely low discharge rates.

edit [MENTION=5372360]magnamentis[/MENTION]

The problem is that 100% is extremely floating point when compared to for example 90%. Leave it charge to 100%, disconnect it immediately after it reports 100% and you'll see it dropping to 99% quickly. Let the charger connected longer and it will drop slower... The variation is very big.

At lower levels it behaves a little differently when you disconnect the charger.

In any case, it's better to not make any conclusions from measurements which are based on this kind of data (immediately after disconnecting the charger) at all. I always check it throughout various points during the discharge cycle and that way I get some pretty consistent numbers.

But we're getting OT again. Simply I'd like to know how did they reach and measure such numbers. That's all.
[Nexus 5 Original Android Development] magnamentis:
again

again, yes it's correct that 100% is not a precise starting point but neither is 90 or 80% even worse because 90% is between 89.5 and 90.4% thus twice the range than from 99.5 to 100.

however if you want o know the real discharge you have to look up the battery voltage, that is quite precise to start with.

regards

EDIT: Now we came from display discussion to battery measurment discussion and should stop it here, it's too many OT posts now. we can go to PM if this seems

worth to continue :)
[Nexus 5 Original Android Development] i860:
I know is just a benchmark but the performance is amazing on Franco kernel ..
[Nexus 5 Original Android Development] bleuxeon:
I am sorry, but all your posts are sssssssoooooooooooooo long that I never read them anymore but when it's happen all I read is wrong.

This last post is an other sample on how you can disinform people.

[Nexus 5 Original Android Development] dazz87:
I have no issue getting 1% overnight. Best I got was 9 hours with only 1% drain (90-89%). No UC or UV.
[Nexus 5 Original Android Development] STXInnovation:
Thanks Mr. Franco, just bought your application on the Play Store.

Does this kernel, by any chance, alter the ear-speaker quality? I've noticed that voices are crystal clear. Maybe it's just me getting used to a new phone.
[Nexus 5 Original Android Development] aeppacher:
Is it intentionally made to prevent us from setting cores on touch to 1? On my kernel on the gs3 I always had it with 1 core running and the others kick in on demand. This would decrease battery usage when just screen on when you aren't really interacting with the phone mainly reading. Is it possible to do this, or is the usage too demanding to allow this?
[Nexus 5 Original Android Development] gregman26:
Your N5 is OC ?
[Nexus 5 Original Android Development] Chad_Petree:
Guys I flashed r14 and then flashed the stock kernel again using the backup of the kernel I made with Franco kernel updater and now my phone stutters and lags from now on , is anyone else having this issue?
[Nexus 5 Original Android Development] i860:
Hi

No oc i uv -50
[Nexus 5 Original Android Development] locke84:
Use cataclysm, switched to art just fine in r14 and r15.. Running smoothly here
[Nexus 5 Original Android Development] DerItaliener:
Sleeps like a baby

I seriously didn't believe all the ppl who said they got ~1% battery drain over night, so I wanted to try it by myself.

My Setup:

Stock ROM

Franco Kernel 15v6 ( -75mV, rest default )

Location off, WiFi Off (Wife shuts WiFi router off every night), 3G Mobile Data on, LightFlow on, Sync On( 2 GMail Push Accounts)

The only thing I have to say to the Result is "Wow", just wow...
[Nexus 5 Original Android Development] Savant:
Its a good feeling when it happens to another.
[Nexus 5 Original Android Development] Mevordel:
People ask for settings: Omni, No Google services installed, 2 IMAP push, auto brightness, no undervolt, underclock to 1036 about halfway through, readahead set to 128, all other settings stock. WiFi power saving on all but an hour. No "battery defender" junk installed, dark themes where possible. Location set to device only.

I'm on the same cycle (no charge) at 29% now.

[Nexus 5 Original Android Development] BeeDubz:OneX:
Does this work on any ROM cos I'm in droidkang n all I get is boot loop when flashed
[Nexus 5 Original Android Development] DerItaliener:
It works on anything that is not CM-based (which Droidkang unfortunately is).

Sorry Mate :(
[Nexus 5 Original Android Development] BeeDubz:OneX:
Ahh that explains the boot loop then lol
[Nexus 5 Original Android Development] Tomatot-:
I've an amazing battery life with last r15 and great performances, very happy with it.

I could have been until 5 SOT I guess.

4hours of music

videos and web in wifi mostly

That's all
[Nexus 5 Original Android Development] occtec:
That's fantastic, did you leave kernel settings at default or make some changes?
[Nexus 5 Original Android Development] franciscofranco:
No.

There are no miracles, if you want lag-free game performance will be hot. Don't worry though, it throttles inteligently, I did a stability test yesterday and it kept my device in under reasonable temperature during all the test by throttling enough. Let it be hot, my thermal driver will protect your device.

This is not a GS3. Here I've set that two cores are always active. Its more expensive to online/offline cpu1 all the time than leave it enabled during screen on. Its been discussed, tested, experienced, the performance gain is enough to justify it and saving all the expensive routines to turn the core on/off all the time. Don't bother asking I won't change this behavior.
[Nexus 5 Original Android Development] Tomatot-:
Nope I change nothing, I just trust Franco ;)
[Nexus 5 Original Android Development] occtec:
When should we see this released as official?
[Nexus 5 Original Android Development] franciscofranco:
When I decide that its ready.
[Nexus 5 Original Android Development] occtec:
Thanks matey, just waiting on the arrival of my nexus replacement today can't wait to try r15 official. Have used r14 and absolutely loved it BUT I can see you've made some awesome changes to r15. Have also purchased your FKU app as appreciation. Thanks Franco keep up the good work, really appreciate it! ;)
[Nexus 5 Original Android Development] aeppacher:
Thanks, was just wondering. Haven't had any time to put into researching the lastest from Qualcomm.
[Nexus 5 Original Android Development] PresidentMcCain:
Sadly we know Qualcomm is definitely putting this S800 chip into the wrong thermal envelope hence the necessity for thermal-engine (I saw it on all Snapdragon 800 phones' ROM dumps, e.g. LG G2, Samsung Galaxy Note 3).

Did not see thermal-engine on the S4 Pro (1st gen) or S600 phones' ROM dumps.
[Nexus 5 Original Android Development] jdec529:
Franco, got a quick question. After reading about how the cooler display calibration is achieved. Is there any chance adverse effects.
[Nexus 5 Original Android Development] Savant:
Its perfect minus a few things it makes not want to change to a different kernel. <what sorcery is this?>
[Nexus 5 Original Android Development] peikojose:
Everything working fine here, using r14 and waiting for the next version..

Only problem (And I think it's a problem) is a constant reboot using Antutu...

I hope to get color control soon..

Best regards...
[Nexus 5 Original Android Development] occtec:
Or the known SMS bug with nexus 5. Try running this program and see if you are secure https://play.google.com/store/apps/details?id=com.bluebox.labs.onerootscanner ;)
[Nexus 5 Original Android Development] drawde40599:
How is it achieved ? If its the same way as he did on N4 then u have nothing to worry about .
[Nexus 5 Original Android Development] doubleho:
it reboot when i turn on the device wih wifi on,on latest r15

test quite a lot of times,it happens only when the wifi is on

sorry,confirmed it reboots even when wifi is off, non stop reboot until i play with the phone for a while

stick rom,latest r15
[Nexus 5 Original Android Development] J132wray:
From dead battery to full charge in 2.25hrs. With heavy use i get 6hrs screen on time. So awesome!!! Much better battery life than my Nexus 4.
[Nexus 5 Original Android Development] Savant:
Don't have any reboots with WiFi on or off. So, what are you doing to make it reboot? This kernel is stable with stock and other ROMs I've tried.
[Nexus 5 Original Android Development] doubleho:
i did nth,try to reboot it and leave it on the desk for a few minutes

if i open any app after a reboot,then the reboots stop

if not it just keep rebooting

im on stock rom with uv -75, this didnt happen on r14 or any previous version

i usually play with my phone after reboots.so i didnt know the issue until last night i rebooted and left it on the desk
[Nexus 5 Original Android Development] dwang:
Here are my cpu and battery stats with the latest r15 test.

No gaming

Mostly browser, YouTube, videos, tapatalk, reddit, texting.

Location off, Google now enabled, Exchange sync every hour, twitter every hour, beautiful widgets every hour, Google apps syncing

uv -50

lux auto brightness app

The CPU is spending most of its time at 1.2 (due to touch boost) and it seems like its spending less time at 300 than the previous r15 and r14, but battery life has been pretty good.

This is pretty typical SOT of what i'm seeing running franco without gaming (~4:30 using mobile data only, ~5 using mix mobile/wifi, ~5:30 using wifi only)
[Nexus 5 Original Android Development] Savant:
Stop undervolting and see if anything changes..
[Nexus 5 Original Android Development] franciscofranco:
That's exactly what I wanted to see. Reducing the display voltage probably helped in balancing things out which makes me very happy. Thank you.
[Nexus 5 Original Android Development] doubleho:
just tried,still happens......
[Nexus 5 Original Android Development] franciscofranco:
Where are the logs?
[Nexus 5 Original Android Development] doubleho:
sorry can u please teach me how to send the log

i just flashed r14 and see if this still happen,if.yes,hen thatz probably my problem...

confirmed no reboot on r14,after a few test
[Nexus 5 Original Android Development] javacody:
Almost 6 hours SOT time with latest r15. Not as nice as the 7 hours I got yesterday.

Franco, I know you made changes to improve performance, but any chance you would consider some kind of flags to switch back to the battery life of the previous test kernel?

If not, almost 6 hours SOT is not too shabby.
[Nexus 5 Original Android Development] doubleho:

dunno how to show u the log.but.i made a video on how the issue is like with my nexus 7 2013,the qualitiy isnt good
[Nexus 5 Original Android Development] aeppacher:
You guys shouldn't be running custom kernels if you can't pull a kmesg:

"Section 3: last_kmsg

Ok, the last thing is last_kmsg. When android kernels crash, they right to last_kmsg so then you can find out what's going on. This is usually for issues such as random reboots and other various kernel panic symptoms. A kernel panic happens when the kernel tries to do something it can't. It doesn't mean wrong permissions, it could just have errored out on something and died which can cause a few things. Anyway, developers REALLY need this if debugging a kernel because it gives us a viable way to see WHAT it's trying to do instead of trying to guess what it is trying to do

How to get a last_kmsg:

This is super simple and the same on all phones no matter what, what you need is adb up and running (or terminal emulator) and either in adb shell, or terminal emulator just type

cat /proc/last_kmsg > /sdcard/last_kmsg.txt

or you can do

adb shell cat /proc/last_kmsg > kmsg.txt

and that will write it to your current working directory from cmd.

Hopefully, this way we developers can have our lives be a little bit easier and you can learn more about android."

[MENTION=334712]francisco[/MENTION]franco , could you please comment on this? Is this something to worry about with your gamma settings? I don't want to cause any trouble but I'd rather not damage my display (if that is possible). What does [MENTION=4152171]myfluxi[/MENTION] say?

I do like that the yellow tinge is gone though.....Everything else is perfect, games, battery, can't complain.

Thanks

It has already been mentioned a lot. He is thinking of going back to stock colors and letting you set your own values. As for values not sticking in the gamma app he has no clue what is going on since he pushed all the same patches myfluxi posted.

Love the kernel but losing audio fully after using Bluetooth stinks, I have Bluetooth speaker at home and my car is Bluetooth so I use it alotttt. If it made any log I'd tell you what it was but I can't get it to log...
[Nexus 5 Original Android Development] Garrykd:
That was a few test versions ago and the colours are the same. I'm not trying to be ungrateful but better safe than sorry. It is uncharted territory....and yes, I have reverted to stock kernel in the mean time but would much rather run Franco's. :)
[Nexus 5 Original Android Development] nikolkang:
I'm sure that as soon as performance testing is done Franco will have more time for the punch list items.

I'm no expert on the matter but I cannot imagine the color tweaks that come shipped with the kernel are damaging. That being said these are the risks we take on a newly developed device kernel... Kinda comes with the territory. ;)
[Nexus 5 Original Android Development] JNewms:
The colors this kernel ships with will not damage anything.
[Nexus 5 Original Android Development] drawde40599:

Nice battery drain over night, but I have got problems with coverage (I don't know how is this word in English, means that the signal phone it's so low or not exist in the same place where I was signal with my Galaxy Nexus).

[Nexus 5 Original Android Development] franciscofranco:
Hmm it could possibly be a fluke, I didn't notice any drop of battery. Can you test another 24h please?

I have no comments at this point, sorry.

BT stack is stock. Does it happen with stock rom + stock kernel?

Why would you do that?

I don't know what Kernel is that rom shipping with, but if it doesn't ship with my defaults exactly like I set them then its not FK what-so-ever.
[Nexus 5 Original Android Development] casonswag:
Yes fku i tried faux also and said performance when i try to change it rom reboots maybe its a rom issue making it have to be on performance?
