Yep. Suddenly I'm getting wakelocks from sns_async_ev_wakelock and sns_periodic_wakelock that I never had before and msm_hsic_wakelock shot up from 7% to 15%. It's so bad that I have 2 hours of on screen time, but my biggest battery hog in battery usage is still Android OS.

I'm going to run it for another day and see if it gets better. Otherwise, I'm going back to r30.
[Nexus 4 Original Android Development] zFayZz:
Same r30 was way better for battery.. Ill try it put for another day

Dont take so personal i was scewing around ;) conclusion is There starting to release 4.2.2 they always release " over seas " first ,my guess is someone will get ahold of it and release a unofficial build pretty quick for everyone .
[Nexus 4 Original Android Development] tma200:
Done quite a bit of testing and found what I believe is a bug in this kernel that hasn't been adequately described by anyone in this thread so far (Although I imagine others have experienced it).

The data connection using WiFi does not appear to persist long after the screen is off and the phone goes to sleep, when WiFi is set to 'Never' stay on. The normal behaviour on Android for this is to disable the WiFi after around 15-20 minutes with this setting enabled, dropping back to using the mobile data connection (Presumably it leaves it on for a while just in case you turn the screen back on, thereby avoiding constant flapping from one connection type to the other). On the stock ROM and kernel, and on my i9000, this is exactly what happens. Notifications and the like continue as normal during the screen off phase before the phone drops back to using 3G data.

On all the Franco kernels I've tried so far (26 through 30) what happens with this setting is that WiFi appears to remain active (the icon is there) but unless an application is running keeping the phone awake, I won't receive any push notifications until the phone picks up 3G data again after the 20 minute WiFi timeout period. Interestingly in better battery stats, it reports periods of "no data connection" which roughly correspond to the period of time between a minute or so after the phone goes to sleep and when it would formally drop the WiFi connection to pick up 2G/3G data instead.

I can repeat this all day, I don't know if it would show up in any log files specifically but I'm more than happy to attach if I know where this would be recorded.

This is using the stock ROM with no mods other than Franco kernel.

My phone been charged for last 4 hours I have one hour screen on time still sitting at 87% battery . ( stock settings Franco kernel ) aokp ROM , brightness 60%

31 has been best build for battery for me so far , and it dose feel faster then 30
[Nexus 4 Original Android Development] zFayZz:
R31 got me 11hrs moderate use

R30 got me 20+hrs heavy use
[Nexus 4 Original Android Development] franciscofranco:
Do a Google search for those wakelocks, several Google Groups posts about that, doesn't matter if you're on stock rom, stock kernel or whatever you run, those will happen. Don't know what triggers them but its not caused by my kernel specifically.

For example: https://groups.google.com/forum/#!topic/tasker/BPWOkf_f4X0

You guys are too fast in pointing your problems to this kernel.

Hi can you please screenshot me your stock settings.. I messed with mine.. Would be great if the updater had a default setting
[Nexus 4 Original Android Development] noneabove:
Hmm.. I just wanted to point out in regards to this but more particularly the person you quoted, msm_hsic_host wakelock has been playing much better than usual for me. In the past 9 hours I've only had 12 minutes of msm lock, and 3 minutes of sns_async_ev_wakelock. Granted I haven't been on 3g much today, but even when I am my numbers aren't very high :S My only kernel wakelock that's high is powermanagerservice and that's because of a game that glitched in the background and held wakelock for 30 minutes! Very good on r31, loving it :)

I do not give much on benchmarks but I just wanted to share it with you: I noticed that the RAM scrore on Antutu is pretty low compared to the ones posted in the benchmarks thread (total score 15.632/ RAM 1329). On stock I had a total score of around 18k but do not remember the RAM score anymore. I am just posting this because I expected a higher result.

Do not get me worng. I do not want to bother you with things like "omg antutu score dropped 3k!!!1 FIX IT!!1". I am just not sure if this is expected behaviour/a regular score. Is it?

I know it is just a stupid benchmark. If this post is not useful at all, please ignore it.

My settings:

Device: Nexus 4

Kernel: 3.4.0-franco.Kernel-nightly#31

Max Frequency: 1512 MHz

Min Frequency: 384 MHz

Governor: interactive

IO Scheduler: row
[Nexus 4 Original Android Development] Testraindrop:
Well I just did an Antutu run, same settings as you.

Got 17054 total and 1859 RAM.

Made another run, got 12341 total and 1996 Ram.

3rd run: 15895 total, 1950 Ram.

Benchmarks are crap :D
[Nexus 4 Original Android Development] benblb:
r31 is great! I've only been using it for 2 hours 20 minutes, but it has been the best two hours of my life. :p

In the past hour, I have sent some texts, took a few photos, and had spotty cell coverage. Despite all that, my phone only dropped from 92% to 91%. I'm very impressed, Franco! No data drops with r31.
[Nexus 4 Original Android Development] MonztA2:
THIS.

First 2 runs resulted in about the same 15k score. Then after your post I ran it again and got 17.359 total and 1933 RAM.

Keep up the good work Franco! :D
[Nexus 4 Original Android Development] noneabove:
Actually it wont, the app keeps your settings between flashes
[Nexus 4 Original Android Development] alienmind:
2nd that, push notifications are heavily impacted on WiFi. I was about to report something similar.

EDIT: Are you using BetterWifi on/off?
[Nexus 4 Original Android Development] Vangelis13:
Probably a bad download; what rom are you on though? Either flash back to what you had before or revert to a backup. Don't wipe cache after the flashing unless a dev recommends you to. Particularly for kernels you don't have to wipe cache.
[Nexus 4 Original Android Development] consolidate42:
That's not quite true.

The benchmark does accurately reflect how the governor behaves when subjected to varying levels of loads. I guarantee that if your phone was cool to start with and you ran the benchmark with the 'performance' governor you'd get a score of ~17000+ That large discrepancy in scores has to be due to either thermal throttling or quirks with Franco's implementation of interactive.

With a heavy UV to stem heat(I'm using motley's b10) I get ~17000-18000 on every single run of Antutu.
[Nexus 4 Original Android Development] ctfrommn:
OK, then clear app data and flash again.

I was on stock rom, rooted and have an unlocked bootloader.

Dont have a custom recovery installed...

Is it possible to flash the stock.img via fastboot and try to boot?

Or what I should do?
[Nexus 4 Original Android Development] tma200:
Nope - nothing about my installation should mess with the WiFi, no battery savers etc. I'd imagine this has to do with changes made to save battery or updates to the wifi drivers that perhaps need to be better tested.

Yes, I realize that which is why I'm testing for longer to see if it's just a fluke. I'm not saying it's the kernel at this point, just reporting what I'm finding so far. I just thought it was odd to have it suddenly come up like when the only thing I've changed was the kernel.
[Nexus 4 Original Android Development] ian577416:
You can always judge the quality of a kernel by how quiet the thread is.:rolleyes:
[Nexus 4 Original Android Development] Globespy:
Is r31 still keeping the phone as hot as a toaster oven?

Shame no UV available.... Faux has this and phone is always cool.

Just seems like a sensible thing to do when the phone clearly has thermal issues, which can't be good for hardware life span when it melts chocolate bars within close proximity. ;)

I'm all for Google pure experience, but surely that should mean they are smart enough to resolve the hear issues?
[Nexus 4 Original Android Development] drawde40599:
Not sure what build your on but there is no heat issue here with Franco kernel , stock kernel is the kernel that gets hot not Franco

Maybe search is not working or something right now, but Franco has expressed his opinions and plans in regards to UV multiple times. He is a slow(not so slow, really), steady, successful kernel dev who doesn't go for gimmicky stuff **cough** sweep2wake **cough** and adds features while maintaining balance and stability. UV isn't here yet per his line of thinking.
[Nexus 4 Original Android Development] Prod1702:
Are you on cm. cm was hot for me until I changed Roms now there is little to no heat at all.
[Nexus 4 Original Android Development] franciscofranco:
This kernel doesn't have any heat problems, it throttles when it reaches 60ºC on the CPU - soon to be 55ºC because I'm finishing some changes on the thermal driver to not lag games when its throttling.
[Nexus 4 Original Android Development] NoLunchBox_:
Idk how everyone's phone is doing but mine is having heat issues like that other guy. Its a lot warmer just doing regular things.

Just letting you know, switching to faux won't do you any justice if you don't know how others are performing with the latest release.

I guess 90% of the people aren't having heat issues, but I can vouch and say I'm one of the few unlucky ones that is having heat issues.

EDIT: For the record, I've been on WiFi all day. No 3G cuz I know that would make it warm.
[Nexus 4 Original Android Development] sucre213:
For me，under 3g the back will be hot after web browsing for somet time

but no hot feelings while under wifi whatsoever

even while playing 3d games it is only a little warm

For those who had hot problems, I suggest check whether there is an app that keep connecting to the internet while it is under 3g
[Nexus 4 Original Android Development] albundy2010:
You want UV?

Get his source.

Change the voltage tables.

Build and flash it.

The end.
[Nexus 4 Original Android Development] drawde40599:
Must be the ROM or time for FULL wipe since 99 % don't have heat issue with build 31 . its what I would do anyway
[Nexus 4 Original Android Development] consolidate42:
^^^

That's how I would want to test my UV values, by rebuilding the source for each tentative adjustment.
[Nexus 4 Original Android Development] Rivermind:
Assuming a sane build environment (which I would expect the Linux kernel to be), making changes and rebuilding would only require recompiling the changed files and dependencies.
[Nexus 4 Original Android Development] consolidate42:
Still not practical to test for stables voltage values for each clock speed.

Nope no issues with the ROM as how I didn't just flash the kernel and started complaining. I was first on MiNCO with R28 and it was fine. Then I flashed R30 and it was a little warm so I figured I wait for the next release.

Then when R31 came out I flashed that too. The phone was still warm after that too. So I flashed Paranoid android and still the phone kept being warm. So then I flashed codefire and I'm currently on here waiting till Franco releases a new one that doesn't make my phone warm.

I'm not going to lie, the battery life has been really good. It just its been warm. Just letting Franco know. I mean not all chips are made equal.
[Nexus 4 Original Android Development] DowntownJeffBrown:
Nope mine got really hot and was losing battery time right around r22 and so I had to go elsewhere and every couple builds would flash Franco again but was getting the same results. Then on r30 the heat went away and on r31 my battery got amazing 5 hours screen on time with all mobile data best battery by far that I've gotten on any ROM. Right now Franco is were its at and he seems to be going in the best direction IMHO.:thumbup:

Then since you want to test various voltages just merge in a control interface instead.

Just saying if you want something either add it in yourself or use something different.
[Nexus 4 Original Android Development] noneabove:
Just titanium backup the app :)
[Nexus 4 Original Android Development] consolidate42:
I personally don't care, I just find your response to a unreasonable request equally unreasonable.

Someone wants UV as a feature and obviously Franco isn't obligated to accommodate him. But it's pretty facetious to tell that person to simply 'code it himself' as if it were a trivial task - because if it were, we'd have it already.

Better advice would simply be to suggest another custom kernel with UV.
[Nexus 4 Original Android Development] formicae:
It's three numbers, if it's going to slow down kernel dev to have him implement a backup function for the colour tunings, I'd rather you just write 'em down or remember them.

[Nexus 4 Original Android Development] Serious_Beans:
Titanium backup to freeze them or get that autostart killer thing. Disables things from starting up when you boot.
[Nexus 4 Original Android Development] STIawdFTW:
Thanks. Neither of those are bad for your phone like task killers (now that I was made aware lol)?
[Nexus 4 Original Android Development] pedxing:
Sorry, all joking aside, there's a really nice app called System Panel which will help you find out what you need. It will simply list all the running apps, services, android os or not and show the amount of CPU utilized by each process. By reviewing that, you can find "misbehaving" apps. The official FB app is actually pretty notorious for misbehaving. It's recommended you use a third party alternative.

What the System Panel app (or others like it show) is the CPU seconds consumed by each process...if it's 0 to 3 seconds over a few hour period, the app is in a normal dormant mode. It is in ram so that it can spring into action in no time at all but it will not consume any battery. Any app that has a sync function will have a background service process as well as the front end UI process. This is normal. If you see a lot of activity, it means your sync schedule is very frequent or the app is misbehaving. I typically set email, weather widgets, etc to sync on an hourly basis. That's plenty. Managing your social media is a bit of an art, of course. Depends on how dialed in you really "need" to be.

But the main thing is find apps with crazy consumption and remove them. Find alternatives. It's like app darwinism...it's the only way those devs will learn. :)

---------- Post added at 04:41 PM ---------- Previous post was at 04:37 PM ----------

This is a good sugestion. And if you have ICS and up you can disable apps without removing them. TiB provides similar functionality. The only time this is really needed is for the background service running apps...other apps that never get used will eventually never get pre-loaded into memory by the mem manager.
[Nexus 4 Original Android Development] GrandMstrBud:
Flashed it just fine. On first boot I went to open system tuner and it did a quick reboot. Not sure if it was a full reboot though but after that it opened everything fine. Can't really tell if it's much faster but hoping the battery life is as good as the GN kernels.
[Nexus 4 Original Android Development] STIawdFTW:
Ya my email is set to never sync. I just hit refresh when I want to check my emails. I just deleted the facebook app it annoys me and I don't really use it anyways. Thanks for all the info I'll look into it.

Is this problem "kernel related" or "ROM related"?
