All stock here only -50mv accross freq. 34% left. 14h34mins/4h28min screen on. Autobrightness all day. Location on. Google now on but greenified. No hard core gaming. A couple of calls. Texting most of the time. Some youtube and music. Cannot be happier. Also I do not think underclocking will give you significant battery gains...at least judging from my results...

Anyone else have Android System constantly keeping the phone on and not letting it enter deep sleep? Immediately after flashing this kernel I got this issue and it seems to persist. Charging to 100% right now and then will reboot and see if the issue goes away or not.

Will report back if the issue is fixed.

Sucks because Better Battery Stats doesn't work for 4.4 yet so I can't see my partial/kernel wakelocks!
[Nexus 5 Original Android Development] caribouxda:
Deep sleep is app related issue. So find which app keeps it awake.
[Nexus 5 Original Android Development] franciscofranco:
Just pushed!

Did you try increasing suspend frequency until the audio skipping stops? I can't reproduce it on my N5 :(
[Nexus 5 Original Android Development] JNewms:
There is a better battery stats beta that works. It's on XDA
[Nexus 5 Original Android Development] :
It happened literally right after I installed this kernel. Before when I was completely stock I did not have any Android System deep sleep issues. Could it really be an app if the issue occurred minutes after installing this kernel?

Regardless still charging to 100%! Should be there in 30 min or so, will see if the issue still persists after a full charge and a reboot.
[Nexus 5 Original Android Development] JNewms:
It's an app issue. I am getting amazing deep sleep with this kernel. Download the bbs beta and check your wake locks
[Nexus 5 Original Android Development] PDP///M:
Hey Franco, any chance you can add stock governor and settings to kernel as well? Thanks for all your hard work.

Awsome battery life with great deep sleep. Stock settings 0.1% drain overnight

Nope! I owe everything to Franco, even paid him $5 for it ;)

Thanks for making this kernel Franco, it's my first time ever flashing a kernel and yours (including the updater app) was very user friendly indeed.

I've been reading a bit about undervolting throughout this thread and someone mentioned that there was a guide on undervolting posted on Android general forums. I was wondering if anyone can confirm if the following thread is relevant/right about undervolting:

What will ramdisk do for the phone performance wise?
[Nexus 5 Original Android Development] webvictim:
I had a few audio skipping issues with the screen off for the first time today on r13. If it happens more often I'll try increasing the suspend frequency. I'm curious as to why the issue never came up before though, I've had the same use pattern (Spotify over Bluetooth in my car) for a while now and use it for at least an hour every day without any issues. In fact, I was on r13 and using the streaming for 3-4 hours yesterday without a single problem too. Weird.
[Nexus 5 Original Android Development] JNewms:
Stock settings won't be added into it. On the 4 he eventually added ondemand, but it was not with anything stock. I would imagine it would be awhile before he adds ondemand though, his to do list has a few other things that he plans on working on before anything else.

How come my UV - 25 doesn't stick even when set on boot? It returns to 775mV (standard value) after reboot. Other settings set on boot stick though.

I had the same issue with FKU 11.0.3 on my Nexus 4. I long-pressed the voltage option, checked set on boot, then went and selected my voltages. They would never stick after reboot. Eventually, I unchecked it, changed the voltages up and down, went back and then re-checked the box. After that they were able to stick.

I'm pretty sure some FKU bug is involved there, Francisco can you please look into it ? It seems like the order you do some operations has something to do with it.
[Nexus 5 Original Android Development] JNewms:
I thought my voltages weren't sticking after boot. Then I realized it was taking a couple minutes to get all of my supersu toasts after booting up. Wait until you've seen the toasts then check to see if your voltages are how you set them.

If you are able to reproduce exactly what you're doing to make them not stick, let me know and I'll run logs to forward to Franco. He's asleep at the moment, but I'll make sure he gets them tomorrow.

Easiest thing to do is to grab the images right from Google. That way you always have them if you need them. Fastboot flash or something like flashify.
[Nexus 5 Original Android Development] misterviolinguy:
Sorry if this has been mentioned, but I couldn't find a definitive answer with search, so here goes:

Whenever I use this kernel, I get massive battery usage from stuff like wifi, android os, android system, etc. I always thought that it was probably an artifact of repeated dirty flashes, so largely ignored it. However, these past couple days I've found that it's easily reproducible:

1. Flash the 4.4.3 zip from Google. (Results in a completely new system, wipes userdata, etc)

2. Install SuperSU + TWRP.

3. Log into Google, install apps

Now, if I leave it at stock kernel, there is about 3% battery drop overnight (7hrs), but if I flash franco's kernel (and change NOTHING else, same network, same wifi, etc...) there is about a 10% drop in the same time frame. Flashing back to stock kernel returns it to 3% battery/night. I've also tried this with PA, with very similar results.

Am I tripping balls, or is this an acdtual issue?

[Nexus 5 Original Android Development] galakanokis:
Tough to say. I think the reboot itself is doing more than just the swapping of kernels. I have had great and terrible battery life on the same kernel in a 24hr period. Some are speculating that it could be radio related with the 4.4.3 radio giving better signal but causing more battery drain compared to the 4.4.2 radio. I flashed 4.4.2 radio last night at 100% and 11hrs later with 2 hrs of screen time with everything running (location sync etc) I am still at 78% battery, using 2.2% an hour. I would say that is pretty good battery life on test 54. I don't do a lot of gaming but I have about 6 or 7 email account sync with 3 of them being active sync/exchange so there's lots going on.

More time is needed to test on my side but I would try downgrading the radio and sticking with one kernel (Franco's) to see how things play out.
[Nexus 5 Original Android Development] franciscofranco:
ups :)

That is absolutely unrelated to the Kernel...
[Nexus 5 Original Android Development] KTT16:
Thanks Franco. Yeah i didn't think it was.. Just thought it happened because of 4.4.3 update.. You know how Google loves to do that sorta thing.. [emoji13]
[Nexus 5 Original Android Development] dipzb90:
Hi all,

I was one of the people who has been having below par battery life on 4.4.3. Like a few people have mentioned on here, I also think it is related to the radio.

I decided to play around with a few things and I seem to have come across a combination which for me is giving me better batter and faster speeds on 4g. My phone is also losing connection to network a lot less.

Here's what I did

1. Changed the TCP algorithm to cubic

2. Disabled fast dormancy. I did this by adding the following line to the build.prop

ro.ril.fast.dormancy.rule=0

I was consistently getting around 2-3mbps more on speed tests. Usually I travel on the trains to and from work, so I lose signal quite a bit, with this I lost signal a lot less.

By the way I'm on the three network in London ....just sharing because it may help someone else :)

No weak radio here, same readings in my usual testing ground, but despite the same Db levels sometimes the network icon show a bar less than with 4.4.2 ...?

I'm in Canada with Bell (Quebec) and wind/Bell (Ontario GTA).

[Nexus 5 Original Android Development] franciscofranco:
It all depends on the carrier and available signal. Here in San Francisco, with T-Mobile I was seeing the worse signal quality I've ever seen in an Android phone. Reverted to 4.4.2 radio, profit.
[Nexus 5 Original Android Development] Tzfardaya:
Franco's kernels have used the 4.4.3 source since it was released (or so I've been led to believe)

as to comparing franco/stock kernel to see which is better, I find using franco's (and properly taming your apps) is generally an improvement over stock. Unfortunately I don't have the time right now for proper tests to verify which is actually better in certain situations.
[Nexus 5 Original Android Development] blackt5:
I run on t-mo and flashed the new 4.4.3 radio the day the images came out. Also in the same boat with fast drain and so so signal. I flashed back to previous version at work and drain seems better and as Franco noted reception seems better. I'd wait another day or two to come up with a positive choice before I come up with a conclusion though.
[Nexus 5 Original Android Development] Skyrocket2Paradise:
Franco for life! Lol r54 and rastakat pretty much no WiFi all on lte
[Nexus 5 Original Android Development] Zyphur:
Checking in for the first time in a bit.

I've also noticed battery draining harder on since 4.4.3.

I've seen on the last few pages some people are using the 4.4.2 radio with 4.4.3.

Is this to help fix the batt and connection issues?
[Nexus 5 Original Android Development] franciscofranco:
What do you think? :p
[Nexus 5 Original Android Development] galakanokis:
I would say the kernel is just fine! The 4.4.2 radio is running much better then 4.4.3 one for me.
[Nexus 5 Original Android Development] Zyphur:
Ty. Will get flashing.

I don't know what to think after that soccer game this morning. Give me some time to get my heard back together :(

At least the kernal has been nice though :)

Edit: Just noticed there's been new gpu drivers out for months. Holy crap I'm behind. Flashed those in flashify.

Now to flash back the 4.4.2 radio.

[Nexus 5 Original Android Development] Pete182:
I'm on omni ROM with the latest kernel and the phone shut itself down while using the gps in the car. Podcast was playing also. This hasn't happened since the very early releases of Franco kernel. I did change room recently though so could it be the rom acting up?
[Nexus 5 Original Android Development] TSFox0317:
im looking for more like detailed specs, like cpu governor, io scheduler. undervolting? overvolvting? governor adjustments?, scheduler adjustments?
[Nexus 5 Original Android Development] granets:
semi pro tip - don't touch the governor settings. Undervolt is also not recommended, because it doesn't lead to a better battery life, and can cause instability. Try lowering max frequencies. I myself just leave everything stock and use Per app Mode for the apps I use the most, like Youtube. In there I lower the max frequency to around 11000MHz and GPU down to 320MHz. This helps for more screen on time in the long run, as less power goes to the CPU and GPU and I see less battery drain when watching videos. Also if you want you can limit the CPU to using just 2 cores, by setting the hotplug load_threshold to 100. Again this is my per app mode profile I use for Youtube and Facebook. Everything else is stock.

I am having a huge battery drain when listening to music. I'm on latest franco kernel and weekly slim rom. For some reason, when I play music with screen off, phone shows as "awake" in the battery stats and I use huge ammounts of battery. Anyone got any ideas?

Also "Media Server" is always one of the top 3 draining things in battery stats, usually second to "Screen"
[Nexus 5 Original Android Development] Bobtehblob:
Franco, could you look into why apps are being uninstalled when flashing Franco Kernel? I recently updated my build of Mahdi Rom, then re flashed your r54. A bunch of my paid apps had then dissapeared. I'm not alone either, there a number of users posting the same problem in the Mahdi Rom forum.

I should also mention that once reinstalling the apps none of their data is lost. Not sure if that has any effect on figuring out what's causing it.

I don't find it normal for the phone to be awake while I listen to music, and lose 5% for 25 minutes of listening while phone is in my pocket. Thats almost as much as I lose when I watch videos... No such issues with previous versions of this kernel.

[Nexus 5 Original Android Development] yak84:
check what other process running in background while you listening to music.

About the awake time , what do you think decodes the compressed file containing your music ? voodoo magic lol it's the CPU , hence the awake time.
[Nexus 5 Original Android Development] granets:
the snapdragon 800 chipset has a dedicated audio processing chip, and that is supposed to help so that the CPU isn't loaded so much. Come to think of it, it should not be using the CPU at all. That's why google stated on the Nexus 5 specs page, that the phone could in theory playback music for 60h straight with one charge, because the CPU isn't involved with the audio processing.
[Nexus 5 Original Android Development] odavans:
Why after each reboot my max cpu freq changes to anything under 1,5 ghz? FKU beta
[Nexus 5 Original Android Development] yak84:
True but that doesn't mean the phone won't be awake.

To your problem , try to see with system monitor in top app section what other process or app using CPU while you listening to music and KILL IT [emoji2]
[Nexus 5 Original Android Development] granets:
On it. thanks for the input :)

edit. That doesn't help alot as the system monitor shows just the momentary CPU usage. I'll just create another per app profile for audio playback and lower the max CPU frequency and see how that goes.

Hello, in fku how can we set a global custom value for +- voltages? For now only multiples of 25 are permitted..

[Nexus 5 Original Android Development] Tzfardaya:
You're referring to the dsp tunneling subsystem.... Yes, audio decoding does take place off the cpu, but that's only after the cpu passes the audio stream to it.. the act of transferring the data stream through the cpu to the dsp requires the cpu to be awake...

Remember Pam is only active when the app is in the foreground and the screen is on...

And you can have system monitor log the events, to track afterwards...

---------- Post added at 08:55 AM ---------- Previous post was at 08:43 AM ----------

The global value shifts amount is hard coded into the fku, you can manually go and raise/lower the voltage at each step to achieve the same end result, or you can use a terminal editor or script file to edit the kernel file directly.
[Nexus 5 Original Android Development] granets:
I am so retarded :D thanks

Will log some info and see what is causing my phone to stay awake while there is music playing. As I said, this is the first time my phone behaves like that. Usually things don't look like that.

EDIT. The scheduled monitoring is a feature of the paid app. I don't have that :) All I can do is record the CPU load graph, but that just tells me what the CPU frequency is at a given time, it does not show the top apps using the cpu :(

Franco,

Ever since r53 I have been having an issue with dropping my signal. Unfortuantly I do not have a log, however I did have this issue happen with r53 on 4.4.2, r53 on 4.4.3 and r54 on 4.4.3 to rule out the newer radio as a variable.

Has anyone else been experiencing this lately? Thanks
[Nexus 5 Original Android Development] Red5:
Kernel dosent mess with the radio/signal. Could have been a coincidence when you were on 4.4.2 and a network issue. The 4.4.3 radio has been known to have lower signal, drop calls and fall back to 3G more frequently.

Try flashing the 4.4.2 radio and see how it effects you and your current setup.
[Nexus 5 Original Android Development] granets:
Don't know what signal you are refering to, but I've noticed that every morning I get to work, if I don't touch my phone, then go in and unlock it, it is not connected to my work WiFi. It connects a while after i unlock it. Then When I go to eat and come back - the same thing. Wifi doesn't connect, before I unlock the screen. Sometimes It connects, then after a while I unlock my phone to check my e-mail and Wifi is disconnected, but connects as soon as the phone wakes up. I'd say I've had this issue since forever. Don't know what it is, but I bet that's what causes some WiFi related drains seen in most kernels, franco's included. But all and all this could be because of the WiFi router and have nothing to do with the phone.

Back to the point, if you are talking about mobile internet dropping - I've seen it to. Just like the WiFi drops I've wrote about above, just that I unlock my phone while I'm outside and occasionally there is no network connection, the phone thinks about it for 5s after waking up, and connects to the mobile network. Just like WiFi drops.

This has been spoted with all 3 radios I have used (the .17, .23 and the newest radio from 4.4.3)
[Nexus 5 Original Android Development] Clauu:
About latest r54 for me at least battery consumption is higher than on r53.. do not why, everything else stock and no i don't have any problem with the radio
[Nexus 5 Original Android Development] bradm23:
I know the kernel doesn't directly effect the radio, however over the past 5 years modifying my phone, certain tweaks and patches have affected things like signal drops.

More specifically, I am taking about have zero bars and it says emergency calls only. I have noticed this a few times. I left my phone on stock kernel for a few days to test and didn't not see this behavior during this time.
[Nexus 5 Original Android Development] Red5:
So try flashing the 4.4.2 radio and see if it helps.
[Nexus 5 Original Android Development] TR2N:
