Great work Franco on 122

After 6 hours of normal usage still on 85% battery. Silky smooth. No crashes

Can't ask for much more
[Nexus 4 Original Android Development] Cantacid:
You might wanna read it again, before sending me to some other thread. I m on M3 already, and would like to be on that. All i am asking is, if i have flashed franco's kernel and then applied the wifi fix to CM 10.1 M3, would it still work.
[Nexus 4 Original Android Development] venkig:
I've been using PA and Franco kernels from 1 Jan 2013 which is when I bought my phone. Now on Franco 122. Do you guys have any issues with phone's touch sensitivity when the phone is plugged into the AC Charger ?

I've had this issue ever since ? How usable is your device when you are charging ? What do you think I am doing wrong ? NO UV, all default, No fast charge.

My swipes stutters and inturn opens up Apps when swiping. It's like it doesn't register the SWIPE MOMENTUM but recognizes that as a TOUCH instead. If I swipe slowly then I have no issues. if I hold the device in my hand while charging the issue is not reproducible however if the phone is on the desk or on the bed and when I try interacting with it I can reproduce ?

Would I be asked to HOLD MY PHONE CORRECTLY ? :D

haven't noticed with n4 but it was definitely a problem on thunderbolt

Sounds like a dodgy charger to me
[Nexus 4 Original Android Development] Cantacid:
Messed up charger is what it is! I had the same issue with a cheap a** charger i tried charging with! Happens with every phone with a touchscreen

I gotas a shutdown during night charge.... So my alarm didnt wake me up so im late to work... Cant attach the log but said something about gpu overflow or something
[Nexus 4 Original Android Development] rhut_tiger:
I had this problem before pa also

If i am not wrong it seems that u you are using a diff charger to charge

Means is not oem charger

Try using that then the problem will not brr there

I had this with my spade Chinese charger
[Nexus 4 Original Android Development] LibiSC:
I using the one that came with the nexus 4 on fast charge with my pc.... Asus motherboard so can supply enough energy

Edit: my battery was almost charged so i suppose the wake up event of the alarm Could have triggered the shutdown... I suppose it was deep sleeping and the bang
[Nexus 4 Original Android Development] CamoGeko:
I highly doubt it mate.

CM team won't help you either if you run into trouble since they don't support any custom kernel discussion.

What motherboard your u have in your laptop wouldn't matter.

I suggest you charge the Nexus 4 from the mains power instead of laptop.

Hello everyone, I bought the nexus yesterday and I have the problem of notifications with wifi and screen off. I flashed this kernel on stock rom thinking to solve but nothing has changed. Is there anything I can do to get the notifications with the screen off with wifi? I am now with stock rom + franco

thanks
[Nexus 4 Original Android Development] Banished Angel:
It's a known issue. Google hasn't released a fix for it yet.
[Nexus 4 Original Android Development] CamoGeko:
Nope, no solution.

Thats a 4.2.2 problem. Wait for Google to fix it.

Push Notification app from play store might help... Requires root to use it

---------- Post added at 02:55 PM ---------- Previous post was at 02:52 PM ----------

Its not really Hard to imagine how they do it... Just keep giving power to usb ports while still plugged in.... My Toshiba laptop has something similar... Pretty cool
[Nexus 4 Original Android Development] el_charlie:
Not a gimmick, with the computer powered off, the USB port delivers more than 1A to charge devices like it is plugged from a wall charger. My Asus laptop does that and I can even charge an iPad.

Cheers!
[Nexus 4 Original Android Development] moe6:
They've been doing this for quite awhile actually. It's entirely true for both laptops and desktop. My Asus laptop will charge my N4 at 1A while it's in sleep too.

<3 Asus.

I use cyandelta and franco's kernel as an additional zip. Still 'sometimes' the Franco's app values does not persist the flash. Is wiping the dalvik-cache during the flash causing this?
[Nexus 4 Original Android Development] PetritH:
Flash latest Paranoid Android and latest franco kernel you won't have any notification issue
[Nexus 4 Original Android Development] SpecRek9:
Hi mates, I've installed r122 kernel yesterday and last night while playing 'wanuganu' my device froze with black screen lit up and after I restarted it just fall into boot loop, so I just turn it off. Today I power it on and it did the same my device is on a boot loop.

Anything I can do to fix it?

Thanks.
[Nexus 4 Original Android Development] Banished Angel:
Boot into the recovery by holding down both the power button and the volume down button. From there try wiping cache/dalvik and fixing permissions and then reboot. If that doesn't work go back into the recovery and try restoring a backup.
[Nexus 4 Original Android Development] drawde40599:
No, do they survive the flash installing manually? I always clear the app before i install rom or kernel updates so i have no clue if thats normal but wipe of those caches isnt y
[Nexus 4 Original Android Development] GerBBAR14_c:
Can someone please point me to a good undervolting tutorial with franco.Kernel?

Thank you :)
[Nexus 4 Original Android Development] LibiSC:
Here is the last kmsg... weird its different from the other time that happened... and it only has info about the battery.
[Nexus 4 Original Android Development] scream4cheese:
-50 to -100mV across the board.

Search the forum.
[Nexus 4 Original Android Development] Arstoien:
There's no tutorial. Start with -50 on all frequencies. Use your phone heavily to stress it. What I do is use Performance governor and underclock the CPU to each of the frequencies for a few minutes and do something intensive. You can test some HDR photos – users report that if you've undervolted too much, you might see artifacts. If all goes well (no restarts), lower with another 25 mV and test again. At some point you'll start seeing either artifacts in the photos or the phone will simply restart on some more heavy tasks. That's when you know you've undervolted too much and roll back 25 or 50 mV.

Most importantly: do not check "set on boot" until you're certain that the values are stable.
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
Everyone loves objective battery tests.

I wasn't happy with my past test because my gf's place's internet is sometimes flaky, and that I used my daily ROM.

In my second test I did the test at my home which I feel has far better internet and is more consistent (subjective observation). I also used a special Nandroid which runs a bare bones copy of CM 10.1 M2. This helps eliminate the ARP fix that people claim kills battery because M2 was built on March 4th???

I ran both tests at night with Battery Test Utility. Somehow I think the brightness sensor is more messed up in M2, but it read 87/255 for the battery test utility app, so expect run times to be worse than my first test. The important part is we can compare the results. I ran CM 10.1 first, and then Franco (last night). I used the browser test which refreshes 10 URLs via wifi at fixed intervals. BTW I used r122 for this test. My last test used r121.

Here are my results:

CM 10.1: 3:14:11

Franco: 3:11:57

If you gave me a Nexus 4 to test with, I'll run these 10 times and do a t-test, but I'm not wasting recharge cycles on my own phone. With that said, I wouldn't say that omg Franco is worse, or CM10.1 is wayy better. I think we need more data. But I think at the end of the day it's not the easiest to spot the differences between the two kernels. Maybe we need more tests to do that, but this is a basic SOT while the CPU is working in the background.

Now flame away.

DISCLAIMER: I love Franco kernel, I do. I'm not here with a goal of proving battery life of one kernel to be better. I'm simply trying to find if there's difference and if so what that difference is.
[Nexus 4 Original Android Development] franciscofranco:
Because those are the default values?

There is no error or panic, it just rebooted because it was instructed to do so. I don't know why though.
[Nexus 4 Original Android Development] michael_ta315:
Hey guys, i wouldn't consider myself as an audiophile, rather as an audio enthusiast, having some knowledges and equipments I was able to produce crisp clear sound and tight, balance bass (not booming, like Beats by Dre) tested on BW P5, C5, Bose QC3 and even on loud speakers :D

-5 gain

5 volume boost

seems to be the best for balance based on my usage. I don't like boomy bass at all :rolleyes:
[Nexus 4 Original Android Development] Bobtehblob:
I'm going to assume you aren't using an equaliser? I've gone with -5 gain and no volume boost, i'm not entirely sure why it's neccesary? For me it's still crazy loud at full volume!

My setup is a pair of klipsch x10s,Nexus louder mod - Unique 2 eq preset. Player is doubletwist.

Also i'm curious as to exactly how you did your testing. By "100% maximized audio sources" do you just mean an array of songs at full volume?
[Nexus 4 Original Android Development] GerBBAR14_c:
Thank you! I shall do this.

Should I use SetCPU?
[Nexus 4 Original Android Development] Banished Angel:
Use Franco's paid app. It lets you adjust every setting you can imagine on his kernel and it's a great way to show your support.
[Nexus 4 Original Android Development] MWBehr:
What interval would you say they're refreshed at? I'm curious what the cores were doing through out this test.
[Nexus 4 Original Android Development] GerBBAR14_c:
Most brilliant! Thank you for letting me know about his app. I bought it.
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
It seems like 2-3 seconds. It loads 10 webpages on a constant loop. More intense webpages like Anandtech and TheVerge kick on 3 cores. but usually 2 cores are running, with at least one at 1ghz. I frequently see 2 cores at 1ghz and 1.5ghz.

If you know a screen recording app that I can use, I can show you what's going on.

I'm in contact with the Battery Test developer and I asked him questions such as caching and he confirmed there is no caching. I also asked him for customizable refresh intervals, and he's working on it.
[Nexus 4 Original Android Development] Underground_XI:
Alright you tell us what you "wouldn't say" = "omg franco is worse, or cm10 is way better". Since your tests are very OBJECTIVE, instead of telling us what you "wouldn't say", can you tell us what you "would say", what is your conclusion? Your tests sound to me more like benchmark scores meaning nobody really gives a **** about those scores because real life experience is what users care about. And yes you are a troll:)

Dalvik cache wiped

Hello there, I need your help please, Someday I downloaded the kernel from your app and decided to auto-flash it, It worked but after, everytimes i reboot, My dalvik cache is automatically wiped and i have "android is upgrading" which is very annoying when i have to reboot twice in a row. Could you help me please.
[Nexus 4 Original Android Development] Hanny:
microstutters

no matter you got it or not, this is literally my experience

explanations:

enter-app-animation-stutter = idle, at homescreen, press on apps that needs some power when opening (whatsapp, chrome, etc), the opening animation is not smooth but noticeably cut into 2 or 3 parts during that 1 second. happens at random intervals, not just the first launch.

notification-press-stutter = pull down notification bar, press on notifications like gmail/whatsapp, initially after pressing, the notification bar pulls up itself and launch the app. however the "automatic pull up" is not smooth, but cut into 2 parts - you see it at the lower third of the screen, then it jumps directly to the top and hide itself. normally it should go from bottom to top smoothly and you see its entire journey. happens at random intervals, not just the first launch.

im making sure my experience is correct by using the kernel for >24 hours before drawing a conclusion.

r120

enter-app-animation-stutter = true

notification-press-stutter = true

r121

enter-app-animation-stutter = false

notification-press-stutter = true

r122

enter-app-animation-stutter = false

notification-press-stutter = false

franco is right, nasty bugs in the hotplug driver are causing those and they can be improved. there is no need of the touch-activate-2nd-core thing which mimics mpdecision.

and yes, thanks for the hotplug controls hooks https://github.com/franciscofranco/mako/commit/f9909f963e89ed28ab744d041351c60fe859c548

its so awesome and user friendly

happy :D
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
How old are you? 5? Grow up. If I reject the alternative that Franco and CM 10.1 are different in battery run time, I accept the null hypothesis which is the status quo that the two kernels give similar run times. I can't prove they are the same. I just can't prove they are significantly different.

No one cares about benchmark scores because the whiners who used to talk about those would talk about getting 8000 on one Franco revision and 8050 on the next revision. The issue is the 50 is an insignificant difference and you're likely to see it with run variance. But if we're repeatedly showing Franco Kernel getting double of stock kernel, wouldn't that be of interest? Of course.

There's no benchmark that really replicates daily use for battery test. But I'm at least providing data. It's 10x more useful than you saying you got 6 hours SOT because that in itself is meaningless unless you compare the data. I'm not saying my data is flawless. There just hasn't been any objective testing. I welcome more test suggestions and other users running tests too. What I do not welcome is idiots like you posting useless comments here about iSheep. Your posts and the ones that got deleted are enough evidence to demonstrate that YOU are the troll, not me.
[Nexus 4 Original Android Development] borito24:
Why can't we all just get along here? I don't get it...
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
I did the test you mentioned in r120 like wiating for the phone to idle with a live wallpaper. I'm not sure if I saw it, but I *think* I saw the microstutter. It's hardly noticeable, but I guess if you're *really* looking for it, it can be there.

Maybe I'm terrible at observing details or something, but thanks for the info.
[Nexus 4 Original Android Development] :
Hey Franco,

Do you think you could move the franco.kernel_updater folder your app creates to /sdcard/data/, and then other folders like kernel_backups in there as well? For consistency. :)

Thanks.
[Nexus 4 Original Android Development] SpecRek9:
Well I wiped cache from recovery and nothing happened, then I wiped dalvik cache and fixed permissions and it passed the logo boot loop but remained stuck on 'starting apps', after that I couldn't access the sdcard to pull the TitaniumBackup folder from adb (like I did before with DCIM folder), I think I shouldn't hit the 'fix permissions' button, so since I had no recent backup I tried reverting to r121 with no luck, so against my will I had to restore back to stock + unroot using WugFresh tool, bummer!
[Nexus 4 Original Android Development] Underground_XI:
I asked you a very simple question, what is the conclusion you got from the tests you did? Why do you have it so difficult to answer?:)
[Nexus 4 Original Android Development] thebryceee:
All I know is my day to day usage is very similar and I get a lot more juice on this kernel than stock.
[Nexus 4 Original Android Development] Underground_XI:
Whaaaat? How dare you?!! You need data, objective testing and proof!! Battery screenshots are not enough!! Even if you claim you are happy with battery life, you still are not allowed to say that!! You need data!! Go to anandtech.com there is Brian there, that guy is the ****!! rofl
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
My scientific conclusion? I think we need more testing to investigate battery life. I also think the battery life is close, and there may not be a big difference between Stock and Franco.

My personal conclusion? I'm more convinced many people are full of crap when talking about battery life. I think there's some other factor giving us bad battery life on the N4, and it's likely to deal with now network operations are carried out. The 3G radio is the biggest hit still.
[Nexus 4 Original Android Development] CamoGeko:
There isn't one at the moment, I suggest you start with -50 on all frequencies and test that for a day. Then if everything goes well, adjust it to -75 and so on. Try not to go below -150mV.

Me and hospital349 are getting together to do an informative kernel thread for new users soon. ;)

Could you guys help me other than fighting each other please ? :crying:
[Nexus 4 Original Android Development] andyli1985:
It's funny to see how one thinks his ways of testing battery life are more useful then others' while they are still subjective. :cool:
[Nexus 4 Original Android Development] Underground_XI:
Did you do a clean install from the beginning? Full wipe then flash rom+kernel and try auto flash again. If that does not help then reflash stock images and reroot. Probably partitions got messed up or try flashing another recovery. Maybe it is recovery's fault.
[Nexus 4 Original Android Development] facile12345:
K thanks, I'll try.
[Nexus 4 Original Android Development] caesium2:
Hello guys, I have a question. I decided to flash to r122 from r116. I did this using auto flash (not the zip method).

After flashing my device rebootet twice and my background was changed. I did not notice any other changes.

I flashed Clockwork Mod some time before, but I realised that it was gone. When I tried to go from bootloader to recovery, it would show the android thing with the red triangle.

Thats why I flashed Clockwork mod again using fastboot: fast flash recovery recovery.img.

After that, some settings where missing. I noticed for example:

my dropbox account was not there anymore, so I had to enter username and password again.

Light Flow was not enabled anymore.

Firefox Sync was still there but it did not show up in settings until I started Firefox again.

Background image was changed.

My question is:

Does flashing a new kernel delete the recovery? Because there was NO recovery I don't think that was the problem.

Will Clockwork Mod stay now? Because I enabled the option that flashing a new ROM would not change the recovery.

Why where some settings missing or changed?

Any help is appreciated!

Thanks!

Franco; you might want to mention the following in your OP:

CAUTION: MY THREAD CAN CAUSE MENTAL DEFICIENCIES.

When I witness all of the quarrelling, flaming and fighting on a daily/weekly basis, it depresses me and causes me to break down and cry. I've been to see a psychiatrist due to all of the negativity that gets injected into these pages. Could I get my money back from the franco.Kernel Updater app I purchased from you? - I need it for more hours with my shrink. :cyclops:
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
Ok, my studies are dissertation worthy, nor are they publication worthy, but it's certainly a more controlled test than ANYONE has done on this board. Stop complaining unless you can offer something better.

I'm sorry I don't have the money to buy 20 phones to test, but review sites do, and they show the Nexus 4 doing worse than the One X and the GS3 in standardized testing.

I'll take numbers and controlled testing over some random dude on this board claiming "OMG best battery ever."

It's a controlled test. Given that no one has done so on this thread so far, it's infinitely better than posts talking about battery life 3 hours after the release of a kernel. We are XDA. I can't believe intelligence on this board has slipped so much since the WinMo days.
[Nexus 4 Original Android Development] yokuyuki:
Users taking screenshots of their SOT after using it during the day and saying it FEELS better = subjective

Running a test in which you hold everything constant but the kernel = objective

Tell me, which is better?
[Nexus 4 Original Android Development] Ok_Kaleidoscope5109:
Man, you should've just enjoyed stock then. If you're not willing to dive into a phone and figure out what's wrong, what makes it better, what to change, etc, then why are yo here? Do you just flash stuff for the sake of flashing? I'm looking at battery life and doing a deep dive and trying to figure out what's going on. What about you?
[Nexus 4 Original Android Development] drmclove69:
How is this in anyway going to figure out whats going on? All your doing is doing tests comparing two different kernels and trying to prove people wrong saying this kernal doesn't significantly improve battery life. You don't know how people use there phone and if they lets say used the phone back when it was completely stock and used it the same way after installing kernel and they get better results. How are you going to sit there and say there lying? It all varies. I use my phone the way it was supposed to be meant to be used and well just enjoy how amazing this phone is coming from a g2x and an evo lte. I honestly cant complain.
[Nexus 4 Original Android Development] kioshi:
I like both:)

But damn, let people post up SOT shots, even Franco has done so in the past...when his gf came for a visit.

Its nice to see SOT with what apps you are running while using the phone, THAT provides somewhat a good feedback to noobs and non tech savy/script reading people like myself.

If you dont like someones test on a kernel, ZIP IT unless you made this kernel, only Franco should have a say in it from now on lol.

Every week fists go flying at each other in this thread, fists should be going in the air for an awesome kernel instead!
[Nexus 4 Original Android Development] tvdang7:
I went back to stock kernel and its back to being snappy. Something about the last few releases make the phone a tad slower.
[Nexus 4 Original Android Development] Underground_XI:
Wow the crappy htc one x got better battery life than nexus 4??? You make such statements and tell me you are not a troll? :D dude go jump off some bridge I feel sorry for you really!
[Nexus 4 Original Android Development] kioshi:
Probably because stock it has all cores on and running min and max CPU around 1.5ghz. I usually feel a bit of extra power when setting phone up after a factory wipe for PA rom..
