francisco, i usually look through this thread for your comments. it was easy to spot you with your old picture. with the new picture, i find it is less than easy to spot you now. the new picture looks great but is there any chance you could change back your picture to the old one? i think couple of pages back someone actually found the picture on the internet. sorry if this issue was brought up before.

as always, your kernel is so far the perfect balance between performance n battery life, even i underclock to 1026mhz, undervolt by 150mv across all clocks. i know you've mentioned many times that you are not going to touch the gpu but, if you are considering to create different preset profiles in the future (performance, moderate, battery saver etc.), i really hope you can give an option to underclock the gpu, if that is possible. i tried to underclock the gpu when using faux's kernel but it keep going back to 400mhz. maybe you could do something about it.

I noticed the same about 102 and I posted it few days ago, tried to do that, but in my case sound control is a file, not a folder, so I can't edit headset boost or volume boost... Already did all kinds of wipes, data cleaning, reflashed...

Will changing the color settings (gamma, for instance) in the app while keeping brightness the same be able to affect how much energy the screen is consuming?

Straight chap checking in, but when I saw him on that Google Hangout a while back I thought hello, sailor! California livin', is my guess.

On topic, can I just confirm that even once headphone gain was removed, there's still a little boost by default in later versions of the kernel? It seems to me that the volume is the same a couple of notches down as it was compared to the old versions but I haven't done any A/B testing.
[Nexus 4 Original Android Development] lowrider262:
Im pretty sure it is, in fact I think Franco even said a while back it has something to do with the touch input drivers (or something like that). I'm on stock rooted ROM and I've noticed the issue only on this kernel (ive tried every other kernel on the board) since back when I first started using it, r86 I think. But it seems to be a lot improved, before it would happen probably 1 out of 5 times id try to unlock, which was kinda annoying, but now its more like once out of maybe 10-15, so its really not even a big deal. Just wanted to see if I was the only one still experiencing this little bug or not.

What are the top couple of offenders in your battery stats screen? I make it through an eight-hour workday with maybe 30 minutes of screen time (I don't use my phone much at work, mostly texting and some non-work-related browsing) with 88-90% left. It's reliable enough that when it's less than that, I go hunting for rogue apps.

[Nexus 4 Original Android Development] lowrider262:
Man that's pretty bad, sounds like my old g2x lol. Are you in a good signal area? Bad signal kills battery super fast. Also is your battery that bad on other Roms, like stock ROM perhaps? Could be a bug in CM. Also if u haven't already, I'd suggest download greenify from the market and use it to freeze Facebook & Google maps, and any other app that runs in the background when you're not using it. If none of that works I'd RMA it, might be a defective battery.
[Nexus 4 Original Android Development] squadz:
Facebook wasn't in my list of apps at all. I used it randomly throughout the day, not long times though.

Betterbatterystats will help you pinpoint those pesky wakelocks and rogue apps.

Autostarts & Greenify are your friends.

Facebook is your enemy.

Friendcaster or Fast for Facebook are perfect replacements.

Google location services (Google Now/Maps) can drain battery in an instance. Greenify/Autostarts can help with these issues.

Also, only sync what you need. I find that it's necessary to sync everything. :)

Installed Greenify, added Google Maps & The Score to it. Is there any recommended apps to Greenify?

Backing up the device now, going to install image-occam-jdq39.zip that was in the folder in the above link, then flash Francos Kernel over it.

[Nexus 4 Original Android Development] squadz:

[Nexus 4 Original Android Development] Arstoien:
@squadz

If you don't use Google Now, stop it. If you use it, you can still do something to reduce the battery drain – stop the "reporting from this device" option in Map's settings. In Facebook turn Sync Interval to "never", and it's good to go. I don't see why people are so quick to jump on it. Maps' and Facebook's only downside is that they use some RAM while on background. They don't actually use any cpu cycles nor cause wakelocks if set up properly.

The first step toward figuring out what's draining your battery is to check your wakelocks with BBS or Wakelock detector (as someone suggested – thanks again for that).

May I also suggest to make a new thread about that. After all that's about a page worth of off-topic so far. Even posting a link to it here would be better than keep on posting about non-kernel related stuff (talking about all included in the discussion, not anyone in particular) ;)

kernel 3.9 changes

Franco- just wanted to mention some filesystem performance improvements & fixes coming in 3.9. Might have some good cherry picks in there.

http://www.h-online.com/open/featur...9-part-1-Filesystems-and-storage-1831197.html

Miscellaneous: filesystemsAmong other work, ext filesystem developers have fixed a performance problem in the JBD2 journalling layer used by ext4, which arose in Linux 3.0.

Support for user namespaces has been added to CIFS, NFS and various other filesystems. This change has not, however, permeated through to XFS, meaning that user namespaces can still only be activated in the kernel configuration if XFS is deactivated. As a result, many distributions are likely to continue to omit support for user namespaces in their kernels.

Changes to Fuse include optimisation of scatter-gather direct IO and support for the readdirplus API. The latter has already been used in NFS and can speed up certain file handling operations.

The sysfs filesystem now has a directory (/sys/fs/pstore/) for mounting the pstore filesystem. In the event of a system crash, this can be used to store data useful for analysing the cause of the crash after rebooting.

Miscellaneous: storageThe cgroup controller for regulating disk read and write speeds now correctly supports hierarchical control groups where CFQ is used as the I/O scheduler. This does not yet apply to I/O throttling, however (1, 2 and others).

Changes to the kernel's memory management can reduce latencies produced by "stable pages" (1 and others). Since Linux 3.0, stable pages protect data already delivered to the kernel for writing but not yet written from further modification. This is important for processes such as checksum calculation and filesystem-implemented compression. More detail can be found in this LWN.net article.

Re: [KERNEL][GPL][N4] franco.Kernel - r111 | M1

Can I ask why do you guys all rate rasbean so highly as a ROM? I can see that its a great ROM, but its not that similar to the likes of Minco. I really dislike the blue theme for example. All the other ROMs get bogged down in way too much customisation with things like pie control which I don't want or need. And stock is just a bit too primitive in customisation for me. Ultimately all I want is a clean stock like ROM with basic options like the modified quick settings and % battery options etc, something that will fully take advantage of Franco kernals performance and give the best battery. What would you all recommend with that in mind? You are all posting amazing battery, which I haven't been able to duplicate on any ROMs other than what I got on Minco pre 4.2.2 :confused:

got a kernel panic while updating from cm10.1 0322 to 0329 nightly with FK 111. Had the same problem when i did a simple kernel update from 102 to 111 on the 0322 nightly.

i don't know why, the last_kmsg is incomplete, i attached it to the post.

i took the following steps.

- switched phone to airplane mode

- rebooted to recovery

- flashed cm-10.1-20130329-NIGHTLY-mako.zip

- flashed openpdroid patch for above rom

- flashed FK r111

- wiped cache

- reboot

both times, the same thing happened:

- nexus 4 boots CM10.1 like usual, and starts with "optimizing apps"

- after that, the popup says "starting apps" instead of "optimizing xyz / xyz apps"

- screen goes off

- nexus 4 does a full reboot with bootloader

- optimizing apps again, language and wallpaper are reset to default

- after that, everything works again as usual, android displays a warning "unexpected error loading global preferences. some of your preferences might have been reset"

About my config:

CM10.1 with FK r111, the only adjustments (all with FKU app) i made are:

- mild UV (-50mV on all frequencies, FASTER binning, worked stable with -125, too), set on boot

- recommended colours, set on boot

- max frequency 1188 MHz, interactive governor, set on boot.

Maybe there is something useful in the last_kmsg, but i doubt that...
