Cpu scales differently on rc1. Seems like cpu usage % is split evenly among all the frequencies, while on r127 it used to stick at 384 most of the time. Rc1 and r127 still give the same sot but the difference is that r127 would last longer because deep sleep was better, while rc1 does not last as long as r127. Same rom same apps same usage.
[Nexus 4 Original Android Development] mgear356:
I dunno if it's me but in rc1, the touch sensitivity is a hit or miss.. I do have more misses when I touch my screen as in its not registering..

Didn't happen in rc0
[Nexus 4 Original Android Development] JNewms:
Think it's just you man. The touch on RC1 has been amazing for me

Dude you better avoid commenting regarding stuff users notice because you are too p***y to tell devs there is some flaw with what they coded. And yes I noticed touchscreen sensitivity was as "precise" as it was in the previous version. The driver maybe updated but does not mean it is better.
[Nexus 4 Original Android Development] JNewms:
Don't know who you think you are talking to me like that. I report what I experience. Just because I'm not having any issues doesn't mean I'm scared to report flaws. Disrespectful punk

Thanks for the response.

Everyday I charge the phone to 100% before sleep (around 11pm) and in the morning (around 6am) I would check the battery used. Battery left would be around 97% or 96%. This is my usual routine, so its done almost everyday since I am on my N4.

But with RC1, the battery left would be around 89% to 88%.

Therefore I thought I should report the observation because to me it is a significant change in the sleep behavior with no other changes to the system except the kernel version.

Placebo? maybe or maybe not?

Regardless, its a super kernel.:good: and thanks:highfive:
[Nexus 4 Original Android Development] Underground_XI:
This is not "reporting what i experience". This is trolling because you reply to users report with something that has nothing to do with what they report. There are 7 people saying battery drains faster and you "report what you experience" saying it is battery reporting flaw while it is crystal clear that cpu scales totally differently. May be if you used nexus 4 instead of nexus 10 you would be able to report better on what you "experience".

But between r127 and rc0 and rc1? Or between rc0 and rc1?
[Nexus 4 Original Android Development] michael_ta315:
Yea =/ well just keep the settings you have now, if it happens again then you might need to wipe. :p
[Nexus 4 Original Android Development] JNewms:
I use both. And I said that because a lot of people had previously reported that they were showing virtually zero drain over night but their battery was " catching up" as soon as they used it. I was attempting to he helpful. You're obviously a punk that gets off by talking tough and picking fights online.

Like I said, I'm offering my experience and as far as the battery, tried to offer an explanation. If it isn't what you wanted to hear, well, too bad. No need to go talking $hit because you disagree or don't like what I said.

How about this? It will surely rile someone up. :)
[Nexus 4 Original Android Development] michael_ta315:
Calm down you guys, you two both have good points. JNewms needs to calm down before pointing fingers saying "it's your fault". Underground_XI you need to calm down before bashing back at him. Me I've not experience much improvement for the touch. I believe it's better than stock but not much better than r127. Maybe it's even placebo for me. :o
[Nexus 4 Original Android Development] Underground_XI:
Between r127 and rc1. (That's what people reported in the last 3 pages, same thing I reported 5 pages before). Not sure which one was rc0, probably missed it...
[Nexus 4 Original Android Development] mammenj:
Yes, between r127 and RC1.
[Nexus 4 Original Android Development] :
I flashed back to r127 and a few hours of deep sleep and I lost 1%, if it was rc1 it would be down 5% , deep sleep just isn't as good, or there's something else, after charge waking up to 88% battery was shocking yesterday

[MENTION=3292224]franciscofranco[/MENTION]

The notification drop down on calls didn't happen again after that post of mine
[Nexus 4 Original Android Development] Skillfulshoe:
I believe he can say whatever he wants. If you don't like it, ignore it. Don't be immature about it and try and tell him what to do.

My touch sensitivity is much better btw. Also I'm currently on 4hr30min screen time with almost 17 hours off charger at 8% left. RC1 so far is the best for me.
[Nexus 4 Original Android Development] franciscofranco:
Nothing happened between r127 and rc1 that can possible affect any type of deep sleep consumption so I don't know.

What version are you running that is not giving you that dropdown after calls? I got lost.
[Nexus 4 Original Android Development] Underground_XI:
If you noticed i did not reply to him anymore so people like you would understand that it was between me and him and there was no reason to continue it;) so be a good boy and follow the advice you gave me in your first sentences, don't be immature:) glad rc1 is the best for you. Enjoy it!
[Nexus 4 Original Android Development] mammenj:
Could it be the scaling logic as mentioned by [MENTION=4519961]Underground_XI[/MENTION]
[Nexus 4 Original Android Development] franciscofranco:
Man, check my github, the last 3 commits were the only thing that changed between r127 and rc1...
[Nexus 4 Original Android Development] albundy2010:
The cpu doesn't scale while in deep sleep. It is in deep sleep.

Scaling only happens when the phone is awake. Screen or a wake lock etc.
[Nexus 4 Original Android Development] Underground_XI:
May be this can help...rc1 interactive all default settings. You can see how it scales. Compared to r127 it spends a lot more time in higher frequencies.
[Nexus 4 Original Android Development] Luigiesin:
Franco, I do notice more drain with rc1... When you drop the first 66,i believe it was 126, battery was actually better...

You mentioned you did change something on the hotplug maybe? Rc1 is as smooth as 666-126 but definitely less battery friendly on idle. My 2 cents ;)

[Nexus 4 Original Android Development] franciscofranco:
Maybe your usage in that day was more aggressive and it needed to scale up more than it did on the day you used r127? Theres no interactive changes between those two versions.

I'm not saying you are wrong, I just trying to establish a base ground for comparison, and what I can see by the reports it seems random stuff. Sometimes I waste 0% during idle for 10h, sometimes I lose 4%, depends on so many things... signal towers etc etc
[Nexus 4 Original Android Development] Underground_XI:
I am pretty sure my usage has been the same...the new touchscreen drivers cannot have any impact on this or you didn't touch them?
[Nexus 4 Original Android Development] :
I was referring to rc1 for the notification drop down after calls

If there's no changes then beats me, I never used rc0 long enough to discern battery life, all I know is that during idle battery is draining more and switching kernels I'm sure its not placebo, I'll go back to stock and observe if behavior is the same with rc1 then report back
[Nexus 4 Original Android Development] franciscofranco:
Its not new touchscreen drivers, I just made a few simple changes. I cant really see how can they affect battery life during idle if during idle the touchscreen is disabled and during screen on thr mechanics are the same.

Im puzzled, I really don't know. Im going to dinner and think.
[Nexus 4 Original Android Development] Ramis:
So i just flashed a new rom and i forgot to save my init.d script for colours.

I got it before from this thread some guy had uploaded a bunch of different colour settings.

Unfortunately i couldn't find it with search.

Does anyone have it bookmarked by any chance?
[Nexus 4 Original Android Development] Underground_XI:
Lol yeah whatever. Bon appetit!
[Nexus 4 Original Android Development] cheapskate88:
Thanks for letting us know. I've been running stock cm10 all day, and I haven't run into any problems. But goddamn, these colors look awful.......
[Nexus 4 Original Android Development] Underground_XI:
Many guys have uploaded in this thread...was it the one with automatic brightness or with brightness set at 50%?
[Nexus 4 Original Android Development] franciscofranco:
Its not whatever. Its a big difference between a new touchscreen driver and a couple line of code difference (around 10-15) in a 3000 lines of code driver. If you are pedantic with battery life then I can also be pedantic on the code I change and the terms we use. Thank you.
[Nexus 4 Original Android Development] Ramis:
I don't remember him mentioning anything about brightness. The script was designed to make the phone screen look more amoled.
[Nexus 4 Original Android Development] Underground_XI:
Idk then...i use this one. If you still haven't, I recommend you purchase franco's app and you can apply the values directly from the app. There is recommended values for colors+all the other color profiles posted by users(there you might find the one you had)

Edit: if it was for amoled like then it was 'obsanity'. Either search here or in general thread there is section about color spreadsheets.
[Nexus 4 Original Android Development] JNewms:
As far as the touch screen goes, it's possible I'm not seeing any of the issues that some are seeing due to the screen protector I use. If you're familiar with the fantom 4 you'll know it's tempered glass. When I put it on my phone I lost sensitivity, enough to where I was getting frustrated with having to make a conscious effort at times to press firmly to get my touches to register. Since franco tweaked the touch drivers my screen is as responsive, maybe even a little more, than it was before applying the fantom 4. Maybe it isn't the most scientific way to test, but it's good enough for me

Idle drain may be 2 or 3 percent more overnight since 127, but I'm still achieving the same overall time without needing a charge. That is why I thought it could have something to do with the way the battery percentage was being reported (read) by our phones. I'm not a dev so all I can offer is my best guess, which I do trying to be helpful. Hopefully something I've said will be of some use to those experiencing issues, that's all I've got.
[Nexus 4 Original Android Development] Haomuch:
It will be so great if you can really solve it! I already know that my suspend backoff is caused by university Wi-Fi wakelock and I usually get more than 1 hour wakelock in 3 hour's screen off.
[Nexus 4 Original Android Development] franciscofranco:
Suspend backoff is not a bug, its a feature, be thankfull that we have it. But I know whats causing it to be bigger than normal. I will release rc2 after dinner.
[Nexus 4 Original Android Development] dark_ente:
[/COLOR]

I always turn on airplane mode at night, and while lost only 2% with r127, I lost 10% with rc1. Signal towers should not be a problem here. I checked BBS and no wakelock, check battery usage and it's still the same. And 2% drain overnight in airplane mode is quite normal, consider that my proximity sensor is always on.

FYI it's not due to battery report wrong because it's consistent. I've had 3 nights with rc1 and as soon as I flash back to r127, battery drain returns to normal.
[Nexus 4 Original Android Development] PunkOz:
The biggest update you could do to your app would be adding some profiles made by you! Like, battery / default / perfomance or Super battery / battery / default / perfomance / super perfomance.

I'm not requesting it, I just think it would be nice and would make more people buy your app maybe! and some preloaded color profiles like PA4, Obsanity, etc. would be amazing for users that are lazy to configure for battery / perfomance.

Question! Will it ever be possible to undervolt the RAM like on PCs? and overclock it? I'm aware you can undervolt GPU too but I don't know why I don't have that option in your app :[

Again, I'm not requesting, I'm just trying to give you some ideas, Ideas that I would do if I knew how to develop for Android :D keep it up!

WAIT LAST QUESTION, WHERE CAN I FIND RC1?! I CAN'T FIND IT ON THE WEBSITE / fKU! :(
[Nexus 4 Original Android Development] Underground_XI:
Rc1? Let me try to give you some ideas, search! Lol couple of pages back there is rc1:)
[Nexus 4 Original Android Development] JNewms:
Do a search for it. It's probably back like 10 or 15 pages. If you search rc1.zip you shouldn't have any issue

I am getting a sns_periodic_wakelock tho but I think that's from my one widget.
[Nexus 4 Original Android Development] franciscofranco:
1 - I will add some presets sometime in the future

2 - Undervolt ram -> maybe possible through the regulator, not sure

3 - Overclock ram -> probably possible, not sure, not aware of that

You don't have any wakelocks that last up to suspend path.

Thanks for the fast reply! Hoping to see profiles and GPU/RAM undervolt near the future, would help in battery and heat! PLUS I haven't seen anyone OCing/UVing RAM, would be an unique feature.

Hey guys, finally got the chance to flash the Franco kernel today - but just want to run a quick sanity check by someone who can hopefully help. I'm running CM10.1 and I'm going to install via zip in recovery mode. I don't need to clear the caches - correct? Also when I install a new nightly from CM10.1 that wont over-write the Franco kernel?

No need to clear caches, just flash away.

You'll need to install Franco's kernel after each nightly as they contain a kernel image (boot.img).

Check your recovery, seems your kernel is not being installed.
[Nexus 4 Original Android Development] mosd:
sorry but what do you mean by check? I used twrp and installed cmrw today and nothing works? Dont seem to install? Installed cwm via the toolkit
[Nexus 4 Original Android Development] zephiK:
This is why you don't use toolkits. Can't even solve a simple problem with recoveries.

1. Download kernel

2. Boot into recovery

3. Flash it.

It can't be any more simple than that. Do you need a toolkit to flash a kernel too? Or just use auto flash within the kernel app -_-

Just to show what R19 version can do :) I will drain the battery all the way and post another screenshot when it is around 5% or so. This is on CM10.1 + Franco kernel (R19)

Pretty sure u can just install it and forget it. I have the app and I don't tweak much in there, just disabled logging and the other thing in there (i forget what it is). What's more important is ensuring no wakelocks.

U don't have to do much except install although i bought the playstore app. Always nice to support the development.

I've already tried that! Booted into recovery and flashed kernel but it won't flash the kernel! Everything looks ok like it's flashed but in settings it says I'm still on 17,what the he'll is wrong?
