What about screen off max value? Screen on min?

Sent from a frequent flasher.
[Samsung Galaxy Nexus] romeyjdogg:
Screen off max: I've tried 384, 537 and not locking the freq's at all, but they all seem to perform about the same

Screen on min: Tried 192, 384 and no locks at all with not much difference

Does the GPU frequency have much effect on battery life with screen time?
[Samsung Galaxy Nexus] bigknowz:
Battery

Also on Shiny 9/2 and working on battery issues at the moment. How much deep sleep are you getting? What apps are draining your battery? My issue is idle drain > 6% per hour while deep sleep is around 90%. Initial testing points to the cellular / voice (whatever you want to call it) radio. Only have the drain at work, idle drain away from work < 2% per hour.

Are you on 4G? Try to disable it.

[Samsung Galaxy Nexus] FutureGamerz:
In all phones, screen/display is always the highest. It's absolutely normal. Only when you keep your phone idle and sleeping all the time (which your screen on is ~0), phone idle or other processes can overtake screen as the largest battery drainer.

Wow! Your VMMC value is so low. I have it at 1200. Same Vaux value.

If you didn't play game a lot, you should set your GPU to 307. With 307, I can still play riptide GP2 so I think it's ok to have it at 307.

Attached the screenshot for my most recent battery cycle. Fully wifi though ;)
[Samsung Galaxy Nexus] masteryx:
When asked why did they choose to underclock the GPU on GNex, Google's developers said something along the lines of "because of better battery life and only minor hit on performance". I doubt this is new information for many of you, but our GPU's are clocked at 307 MHz by the stock kernel while they are physically built to run at 384 MHz. That's why all GPU's perform excellent at 384 and only some have issues at 512 (mine included), a frequency at which they really are overclocked.

I found that the performance gain from running at nominal speed (384) is quite significant while the battery consumption increases negligibly, so user experience may vary. But rest assured, @romeyjdogg, lowering the GPU frequency won't buy you significantly more screen time. Your low battery life is most likely caused by poor radio reception, as others stated.
[Samsung Galaxy Nexus] romeyjdogg:
I'm with you; I think the radio is a lot of the issue

I am on 4G, yes. I will try going all CDMA

---------- Post added at 06:29 PM ---------- Previous post was at 06:26 PM ----------

Yeah, I don't play many games, just email, web surfing, etc. My VMMC seemed to have no effect @ 1000, so I figured why not?

Very nice stats, I'm jealous!

Thank you for the insight, you learn something new everyday!
[Samsung Galaxy Nexus] bigknowz:
Radio

The issue isn't with data (CDMA / 4G), I have that off. It looks like I'm going to build a Tasker rule to intermittently check for SMS / voicemail while at work and have radio off most of the time. Is your issue also location specific?
[Samsung Galaxy Nexus] FutureGamerz:
More info: http://techie-buzz.com/android/why-...exus-clocked-at-308mhz-instead-of-380mhz.html

2. I noticed u have CM updater. Try switching ROM to Cataclysm ROM. Personally from my experience CM ROM has higher idle drain for me.

[Samsung Galaxy Nexus] evilssj4:
[MENTION=2828302]pcphobic[/MENTION] so today it happened again where the battery drained a lot on my drive to school. When I left my home the phone was charged at 98% and about 40 minutes later it was at 80% and I only turned on the screen a couple of times to check if i had messages. (dont mind the map usage I used that after it was under 80% because I kind of got lost and it was only on for 1 1/2 minutes. Here are the screenshots
[Samsung Galaxy Nexus] bigknowz:
Try this

Seems like my radio drain issue is gone, want to make sure it works for a few days before I declare victory. Can you try this on your way home from school: turn off mobile data and note your battery %. Those yellow bars in mobile network from screenshot look like the problem.
[Samsung Galaxy Nexus] arvylas:
Anyone knows which is the the lowest safe value for the vaux3 voltage? I have it at 2500 but I don't want to cause something bad.
[Samsung Galaxy Nexus] evilssj4:
Yeah I saw that too but when I had checked I had 4 bars of 3G so not sure what's going on. Also, im using 4.0.4 (IMM76K)

LTE-FC05 / CDMA-FC04 I was using the latest radios of 4.2.2 but when I am home it says I am roaming (I have a network extender at home) but I already tested out that it just has an R on top of the bars but I am not roaming and VZW didnt charge for roaming so I think I will flash the 4.2.2 radios again.
[Samsung Galaxy Nexus] pcphobic:
I can see that during your drive to school, your cellphone radio reception was bad. This can cause more drain.

Also, can u try a non-CM based ROM please?

---------- Post added at 11:53 PM ---------- Previous post was at 11:51 PM ----------

Try one day with Smartreflex and then another without. This is up to individual.
[Samsung Galaxy Nexus] evilssj4:
Yeah, just not sure which ROM I should try I've tried about 3 different 4.3 roms and same thing happens the battery drain is there

Edit: I just saw purity ROM is in 4.3 now and its aosp based so ill flash that now
[Samsung Galaxy Nexus] pcphobic:
OK. Also try different radio baseband too.
[Samsung Galaxy Nexus] evilssj4:

Hey boype, before r39 i was getting my whatsapp messages right on time, but the releases after that, even with dtim_skip_override is 1, i dont get my messages instantly. With both 3g and wifi. Mostly wifi.

I'm going to try rolling back to 4.1.1 radios. I have been on wifi all day today at work and my screen usage is 40 mins with battery still at 72%. Usually my second and third highest drainers are phone idle and cell standby, but today second is google services.

I'm guessing 4.3 isn't playing nice with the 4.2.2 radios on my phone for some reason. It's worth a shot!

[Samsung Galaxy Nexus] chikimonke:
I could be wrong, but I don't think we get more memory by removing those features, I think those features simply just don't work when the memory is restructured to allow more to be available to our apps and not the system. Could be wrong though.

r41 up (+HUGEMEM)

Hi,

I just pushed r41 to the download servers. The main new feature is HUGEMEM for the ext kernel, which gives you ~73 MB more available RAM. Credits go of course to mpokwsths. Here is the change log:

update to Linux 3.0.95

extended version only: add and enable HUGEMEM (releases ~73 MB of otherwise reserved RAM. Note that 1080p video recording modes are disabled because of this!)

Revert "mm: lazy cache flushing on non-mapped pages" (could cause occasional reboots)

opp4xxx_data.c: fix incorrectly sized MPU IVA VDD dependency table

ondemandplus governor: remove adaptive timer_rate logic (It is unlikely this gives any power savings and only adds some ugly code)

i/o schedulers: cfq, deadline, row tweaks from Franco Dev Team

ARM: assembler.h: use same WRITE_ALIGN_BYTES on omap4 as on armv6 platforms (since Cortex-A9 has the same amount of L1 cache)

defconfig: back to default 3G/1G vmsplit

hardcode vfs_cache_pressure = 65

hardcode read_ahead_kb = 256

harcode nr_requests = 256

RAMdisk: disable 1080p video modes with HUGEMEM-enabled kernels

RAMdisk: don't set content adaptive brightness to 0 on boot

RAMdisk: swappiness = 35

RAMdisk: small block tweaks

RAMdisk: upstream changes from CM10.2

So I really got convinced with the HUGEMEM thingy. It's just great to have ~10% more RAM available! I implemented a patched file that will (temporarily) remove the 1080p recording modes from the system, so that there cannot be any crashes in the first place. I assume that all apps should run fine like this (like barcode scanners, etc.).

Also, I did not try to squeeze every possible kilobyte for more RAM out of the system: There are attempts floating around which disable the RAM console for 2MB more RAM for example. I decided to not pick up on this, because the RAM console is the storage place that can provide the logs after crashes.
[Samsung Galaxy Nexus] in1400:
Great work, thank you very much
[Samsung Galaxy Nexus] Syfer_Fever:
i thought you will release 3 different version (std,ext and ext+hugmem) :p

Answered yes to both and all is well.

Thanks for your great work.

[Samsung Galaxy Nexus] Charmacas:
Why did you remove the adaptive timer rate?

Nobody has tested it extensive. Maybe 20000 was just the wrong value to set!? I think that the algorithm is very logical and it should really save some battery. Maybe you can give a test version again with adaptive timer rate included and then we test various values. And maybe you could also have a look on the code analyse if it's really doing what it should. :)

I've always had to bump the mpu voltage to get 1500 to run. Take a look and start small, too much voltage will crash also ;)
[Samsung Galaxy Nexus] masteryx:
I can confirm that bumping up the voltage solves this. Mine too crashes at 1500, but turning MPU Smart Reflex off and incresing the voltage to 1430 mV does the trick.
[Samsung Galaxy Nexus] -Jesco-:
thats weird , it(1500) works on 1305mv for me , maybe its device specific ?

[Samsung Galaxy Nexus] stevensoaj:
[MENTION=4615478]boype[/MENTION], would it be a good idea to disable SR by default on the higher clock speeds? It may help avoid the instant reboot some get (me included) when changing to those speeds. I noticed lean kernel is set up this way and allows OC to 1.65GHz. Thoughts?

R41 is great BTW. Great job. :thumbup:
[Samsung Galaxy Nexus] MBQ_:
Although I'll be flashing this extremely soon, would someone let me know if recording videos and/or viewing/recording videos on SnapChat works with the extended versions?

The reason why I'm asking is because I know it didn't work with the 'unofficial' builds that were posted here a while back, and I'm thinking there is a possibility it may work now due to Boype (or whomever it was that originally committed it), removing 1080p recording.

Apologizing in advance if I missed something.

I flashed the r41 ext onto r40 bigmem version, and now I have lost root ,

things i tried befor posting, all of these failed to regain root

1 flash superSU from cwm.

2 re flash r41 and without rebooting flashed auperSU.

P.S. 1 i am on latest touch cwm, also after flashing r41 cwm is aking only to disable recovery flash and not about root bin

2 flashed r40 again and then supersu , root is gained

any reason why I am the only one whos having this problem
[Samsung Galaxy Nexus] Astug:
You're not alone mate.

After flashing r41ext over a fresh install of stock 4.3, SuperSU says "There is no SU binary installed, and SuperSU cannot install it."

I reflashed stock (always full wipe) and checked if SuperSU was OK, it was, so flashed the kernel again (wiped cache & dalvik cache) and the same thing happened.

Any ideas?

EDIT: Fixed by flashing latest SuperSU through recovery. Still weird though.

[Samsung Galaxy Nexus] mfdemicco:
Boype, I'd like to make a request for you to update the 4.2 kernel. 4.3 roms have a major bug in that they have data connectivity problems switching between 3g and 4g. Major fail, in my opinion.
[Samsung Galaxy Nexus] xxSAKISxx:
well i use twrp 2.6.1.0 and the 3 last times i flash something at the end it tell me thst maybe i lost root and i must fix permissions. When i swipe to fix permissions i still got root. At least titanium backup say i have.

Hugemem for 4.2.2

Hi everybody! Since Boype said he won't add Hugemem support to the old 4.2.2 kernel, I built my version, which I share for the ones that (like me) want to use this feature with the old version.

For who might have flashed my previous version, please flash again, I found a few errors on the old one.

Flash it using fastboot:

fastboot flash boot [COLOR="Red"]path/to/[/COLOR]boot.img

The path/to/ means the path where you saved the file.

https://www.dropbox.com/s/xzxp14a7y9irr53/boot.img

To remove 1080p recording from options, just modify with root explorer or similar app "etc/media_profiles.xml", deleting what follows:

<EncoderProfile quality="1080p" fileFormat="mp4" duration="30"><Video codec="h264" bitRate="12000000" width="1920" height="1080" frameRate="30"/><Audio codec="aac" bitRate="96000" sampleRate="48000" channels="1"/>

<EncoderProfile quality="timelapse1080p" fileFormat="mp4" duration="30"><Video codec="h264" bitRate="12000000" width="1920" height="1080" frameRate="30"/>

Save, then reboot. Make a backup of the original file, just in case somtehing goes wrong.

Thanks to boype (whose git i explored to know how to remove 1080p option in camera, and obviously for the great kernel), stuffynet and SoftWorld, who helped me a lot!

i knew that this option was removed in ext version (bigmem), but i though that flashing standard version, i would have had again 1080p.

so now, what can i do? i have also cleared data camera, but nothing..
